Technology is alienating people – and it’s not just those who are older

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/carolyn-wilson-nash-1255329">Carolyn Wilson-Nash</a>, <a href="https://theconversation.com/institutions/university-of-stirling-1697">University of Stirling</a> and <a href="https://theconversation.com/profiles/julie-tinson-277507">Julie Tinson</a>, <a href="https://theconversation.com/institutions/university-of-stirling-1697">University of Stirling</a></em></p> <p>We take it for granted that technology brings people closer together and improves our access to essential products and services. If you can’t imagine life without your smartphone, it’s easy to forget that people who can’t or don’t want to engage with the latest technology are being left behind.</p> <p>For example, there have recently been reports that <a href="https://www.express.co.uk/life-style/cars/1618497/parking-poll-results-cashless-car-parks-card-smartphone-app-only-elderly-drivers-spt">cashless payment systems</a> for car parking in the UK are seeing older drivers unfairly hit with fines. This has led to calls for the <a href="https://www.dailymail.co.uk/news/article-10851103/Esther-Rantzen-tells-ministers-pensioners-not-use-apps-pay-parking.html">government to intervene</a>.</p> <p>Age is one of the biggest predictors of <a href="https://ageing-better.org.uk/sites/default/files/2020-08/landscape-covid-19-digital.pdf">digital exclusion</a>. Only 47% of those aged <a href="https://www.ons.gov.uk/businessindustryandtrade/itandinternetindustry/bulletins/internetusers/2019">75 and over</a> use the internet regularly. And out of the 4 million who have never used the internet in the UK, only 300,000 people are <a href="https://ageing-better.org.uk/sites/default/files/2020-08/landscape-covid-19-digital.pdf">under 55</a>.</p> <p>But older people are not the only ones who feel shut out by new technology. For example, research shows vulnerable people, such as those with disabilities, are also disengaging with e-services and being <a href="https://www.tandfonline.com/doi/full/10.1080/0267257X.2012.691526">“locked out” of society</a>.</p> <h2>The digital transition</h2> <p>From train tickets to vaccine passports, there is a growing expectation that consumers should embrace technology to participate in everyday life. This is a global phenomenon. Out in front, Sweden predicts its economy will be <a href="https://sweden.se/life/society/a-cashless-society">fully cashless</a> by March 2023.</p> <p>Shops increasingly use QR codes, virtual reality window displays and self-service checkouts. Many of these systems require a smart device, and momentum is building for QR codes to be integrated into <a href="https://www.thegrocer.co.uk/technology-and-supply-chain/the-time-has-finally-arrived-for-electronic-shelf-labels-heres-why/661068.article">digital price tags</a> as they can give customers extra information such as nutritional content of food. Changing paper labels is a labour intensive process.</p> <p>Technology pervades all aspects of consumer life. Going on holiday, enjoying the cinema or theatre, and joining sport and social clubs all make people feel part of society. But many popular artists now use online queues to sell tickets to their shows. Social groups use WhatsApp and Facebook to keep their members updated.</p> <p>When it comes to booking a holiday, there is a <a href="https://www.statista.com/statistics/919811/number-of-travel-agents-united-kingdom-uk/#:%7E:text=Overall%2C%20there%20were%203%2C710%20retail,as%20TUI%20and%20Hays%20Travel.">decreasing number</a> of in-person travel agents. This limits the social support to make the best choice, which is particularly important for those with specific needs such as people with health issues. And once travelling, aircrew expect flight boarding passes and COVID passports to be available on smartphones.</p> <p>Essential services such as healthcare, which can already <a href="https://www.tandfonline.com/doi/full/10.1080/0267257X.2022.2078861">be difficult</a> for older and other people to navigate, are also moving online. Patients are increasingly expected to use the GP website or email to request to see a doctor. Ordering prescriptions online is encouraged.</p> <h2>Not just older people</h2> <p><a href="https://www.gov.uk/government/publications/digital-lifeline-a-qualitative-evaluation/digital-lifeline-a-qualitative-evaluation">Not everyone can afford</a> an internet connection or smart technology. Some regions, particularly rural ones, struggle for phone signal. The UK phone network’s plans for a <a href="https://www.bbc.co.uk/news/uk-england-shropshire-61377944">digital switchover</a> by 2025, which would render traditional landlines redundant, could cut off people who rely on their landlines.</p> <p>Concerns about privacy can also stop people using technology. Data collection and security breaches impact people’s confidence in organisations. A 2020 survey into <a href="https://www.mckinsey.com/business-functions/risk-and-resilience/our-insights/the-consumer-data-opportunity-and-the-privacy-imperative">consumers’ trust</a> in businesses showed no industry reached a trust rating of 50% for data protection. The majority of respondents (87%) said they would not do business with a company if they had concerns about its security practices.</p> <p>Some people view “forced” digitisation as a symbol of consumer culture and will limit their technology use. Followers of the <a href="https://www.researchgate.net/publication/228310981_The_Voluntary_Simplicity_Movement_Reimagining_the_Good_Life_Beyond_Consumer_Culture">simple living movement</a>, which gained momentum in the 1980s, try to minimise their use of technology. Many people take a “less is more” <a href="https://www.emerald.com/insight/content/doi/10.1108/JCM-04-2020-3749/full/html">approach to technology</a> simply because they feel it offers a more meaningful existence.</p> <p>One of the most common reasons for digital exclusion, however, <a href="https://www.iriss.org.uk/resources/esss-outlines/digital-inclusion-exclusion-and-participation">is poverty</a>. When the <a href="https://www.local.gov.uk/parliament/briefings-and-responses/tackling-digital-divide-house-commons-4-november-2021">pandemic hit in March 2020</a>, 51% of households earning between £6,000 to £10,000 had home internet access, compared with 99% of households with an income over £40,000.</p> <p>Limited access to tablets, smartphones and laptops can result in feelings of isolation. Many older consumers have developed strategies to manage and overcome the <a href="https://www.tandfonline.com/doi/full/10.1080/0267257X.2021.1945662">digital challenges</a> presented by these devices. But those unable to <a href="https://theconversation.com/how-older-people-are-mastering-technology-to-stay-connected-after-lockdown-165562">engage with technology</a> remain excluded if their family and friends don’t live close by.</p> <h2>Smart change</h2> <p>The solution is not simply to give devices to those without smart technology. While there is a need to provide affordable internet access and technology, and offer support in learning new skills, we need to recognise diversity in society.</p> <p>Services should provide non-digital options that embrace equality. For example, cash systems should not be abolished. There might be a demand for services to become digital, but service providers need to be aware of the people who will be isolated by this transition.</p> <p>Retailers, local councils, health providers and businesses in tourism, entertainment and leisure should try to understand more about the diversity of their consumers. They need to develop services that cater for the needs of all people, especially those without access to technology.</p> <p>We live in a diverse world and diverse consumers need choice. After all, access to and inclusion in society is a human right.<!-- Below is The Conversation's page counter tag.

The alarmingly accurate predictions made 100 years ago

<p>A university researcher has uncovered predictions made in 1924 about what the world would look like 100 years in the future, with some of the predictions proving to be scarily accurate. </p> <p>The Canadian professor Paul Fairie shared a selection of headlines and articles made by newspapers in the 1920s on his X account, showing in what ways the world has changed and how it has remained the same.</p> <p>While some predictions made in 1924 hit the nail on the head, others couldn't be further from reality. </p> <p><strong>Accurate predictions </strong></p> <p><span style="text-decoration: underline;"><em>Car speedways</em></span></p> <p>One newspaper clipping claimed that in the future, cars would be travelling on super "speedways" that allowed them to travel faster. </p> <p>While cars first hit the roads in the 1880s, it wasn't until the 1920s that vehicles became more common, with cities quickly trying to build safe roads to accommodate the growth in motor vehicles. </p> <p>“In the city of 2024, this authority predicts there will be three-deck roads; speedways through the heart of town,” the newspaper article predicted.</p> <p>The article also envisaged monorail express services to the suburbs replacing cars and buses and moving sidewalks (similar to airport travelators) that moved people in all directions, “serving all railroad stations and business districts”.</p> <p><span style="text-decoration: underline;"><em>Women getting tattooed and dyeing their hair</em></span></p> <p>In the 1920s, tattoos were exclusively reserved for sailors, criminals and gangland figures until they became more commonplace. </p> <p>But one 1924 article predicted, incredibly accurately, that by 2024 women would be getting tattoos and dyeing their hair “all the colours of the rainbow”.</p> <p>“Debutantes of 1924 are shingle-haired, sleek-looking maidens with delicately rouged cheeks and provocative red lips,” the article stated.</p> <p>“The 1924 debutante successfully conceals her personality under paint and power."</p> <p>“The debutante of 100 years hence may revert to type and frankly copy her ancestors, who dyed their skins with woad; only, with the modern instinct for progress."</p> <p>“She may go still further and dye her complexion and hair all the colours of the rainbow.”</p> <p><span style="text-decoration: underline;"><em>Women becoming stronger</em></span></p> <p>The newspapers of 1924 also predicted that women of the future would be “physically strong, vital and alert.”</p> <p>One article predicted that women would spend more time in the outdoors, participate in sports, and would be “engaging by choice” in activities that were historically restricted to men.</p> <p>Intellectually, women would be “quick at wit and keen of judgment,” while spiritually, she would “radiate love and good will”.</p> <p><span style="text-decoration: underline;"><em>Remote viewing </em></span></p> <p>One of the most accurate predictions from 1924 was the invention of technology that would allow people to view entertainment "remotely". </p> <p>“Many inconveniences which the touring artist now has to suffer will no doubt be eliminated,” one prediction read.</p> <p>“It will not be necessary to travel great distances. The strain of the concert tour will be dispensed with. Artists may not even have to leave their homes (to perform).”</p> <p><strong>Not so accurate predictions</strong></p> <p><span style="text-decoration: underline;"><em>Horses becoming extinct </em></span></p> <p>One prediction from a 1924 newspaper believed that as cars took over as the main form of transportation, there would be no more use for horses and they would soon becoming extinct. </p> <p>“If a house would decrease in the same ratio as in the last ten or twenty years, it might be easy to tell when the last horse would give up his stall to an automobile,” the prediction read.</p> <p><span style="text-decoration: underline;"><em>Self-launching beds</em></span></p> <p>Another not-so accurate prediction claimed that beds would soon come with a feature that would override the use for an alarm clock, but would come with a mechanism to launch you out of bed in the morning. </p> <p>Describing this futuristic scenario, the reporter wrote: “My bed turns over automatically and I am deposited on the floor”.</p> <p>“Eight o’clock and the switch operating above the fiendish substitute for an alarm clock is operated from school, so at the moment, I am in the same predicament as the rest of the 450 scholars.”</p> <p><em>Image credits: Shutterstock </em></p>

Photos are everywhere. What makes a good one?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/t-j-thomson-503845">T.J. Thomson</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p>We upload some <a href="https://theconversation.com/3-2-billion-images-and-720-000-hours-of-video-are-shared-online-daily-can-you-sort-real-from-fake-148630">3 billion images online each day</a>. We make <a href="https://www.tandfonline.com/doi/full/10.1080/1051144X.2023.2281163">most of these photos on smartphones</a> and use these devices to document everything from gym progress and our loved ones to a memorable meal.</p> <p>But what makes a “quality” photo? Many people, even those who make images for work, struggle to answer. They often say something along the lines of “I know it when I see it”. But knowing some dimensions of a quality photograph can help make your images stand out and make you a <a href="https://medialiteracy.org.au/media-literacy-framework/">more literate</a> media maker and consumer.</p> <p>Quality can be relative, but knowing the various dimensions at play can help you draw on those that are most relevant for your particular audience, context and purpose.</p> <p>I identified <a href="https://doi.org/10.1177/14648849241253136">six dimensions</a> which will impact the quality of photographs. Here’s what I learnt – and what you can apply to your own photographs.</p> <h2>1. Production and presentation</h2> <p>Think of the factors <a href="https://journals.sagepub.com/doi/full/10.1177/1522637918823261">in front of and behind the lens</a>.</p> <p>If you know you’re being recorded, this can affect your behaviour compared to a candid depiction.</p> <p>You might be more or less comfortable posing for a friend or family member than for a stranger. This comfort, or its lack, can lead to more stiff and awkward poses, or ones that look more natural and confident.</p> <p>Presentation circumstances, like the viewing size and context, also matter.</p> <p>A group shot can make a nice statement piece above a fireplace, but it wouldn’t have the same effect as a profile photo. Be aware of how “busy” your image is, and whether the viewing conditions are well-suited for the nature of your photo.</p> <p>Images with lots of elements, fine textures or other details need to be viewed large to be fully appreciated. Images with fewer, larger and simpler elements can usually be appreciated at smaller sizes.</p> <h2>2. Technical aspects</h2> <p>Technical aspects include proper exposure – meaning the image isn’t too dark or too bright – adequate focus, and appropriate camera settings.</p> <p>Some of these camera settings, like shutter speed, affect whether motion is seen as frozen or blurred.</p> <p>If the image is too blurry, too pixelated, or too light or dark, these technical aspects will negatively impact the photograph’s quality. But some motion blur, as distinct from camera shake, can make more dynamic an otherwise static composition.</p> <h2>3. Who or what is shown</h2> <p>Who or what is shown in the photographs we see is affected, in part, by access and novelty. That’s why we often make more photos during our holidays compared to documenting familiar settings.</p> <p>Some people or locations can be <a href="https://journals.sagepub.com/doi/full/10.1177/1329878X221094374">under-represented</a> and photographing them can lead to more visibility, and, depending on the context, a more empowering framing.</p> <p>Consider in your photography if you’re including people who are typically under-represented, such as older individuals, people of colour, people living with disabilities and queer people. Also consider whether you’re representing them in stereotypical or disempowering ways.</p> <p>As examples, <a href="https://www.tandfonline.com/doi/abs/10.1080/22041451.2022.2137237">when photographing older people</a>, consider whether you’re showing them as lonely, isolated, passive, or in need of mobility aids.</p> <h2>4. Composition</h2> <p>Composition includes positioning of elements in the frame, the balance between positive and negative space, and depth, among others.</p> <p>Generally, images that centre the subject of interest aren’t as visually engaging as images that offset the subject of interest. This is what’s known as the <a href="https://www.adobe.com/au/creativecloud/photography/discover/rule-of-thirds.html">rule-of-thirds</a> approach.</p> <p>Likewise, images that have no depth are generally not as interesting as images with a clear foreground, midground and background. “Seeing through things” with your compositions can help increase the visual depth of your photos alongside their visual appeal.</p> <h2>5. The psycho-physiological</h2> <p>The psycho-physiological concerns how the viewer reacts to what is shown.</p> <p>This includes the <a href="https://psycnet.apa.org/record/2011-07236-024">biological reaction</a> we have to seeing certain colours, for example the way the colour red can increase our heart rate. It also can include the feeling we have when seeing a photo of someone we know.</p> <p>The most powerful photos use colour and other elements of visual language strategically for a specific effect. Looking at these images might evoke a specific emotion, such as empathy or fear, and influence how the viewer responds.</p> <h2>6. Narrative</h2> <p>Narrative concerns the storytelling quality of the image.</p> <p>Images can show something in a literal way (think a photograph from a real estate listing) or they can tell a bigger story about the content represented or about the human condition (think about some of the iconic photos that emerged during Australia’s <a href="https://journals.sagepub.com/doi/abs/10.1177/1329878X211008181">black summer bushfire season</a>).</p> <p>Literal photos help us see what something or someone looks like but they might not have as much of an impact as iconic photos. For example, the well-known photo of three-year-old Syrian boy Aylan Kurdi’s lifeless body on a beach in Turkey <a href="https://www.reuters.com/article/idUSKBN14V2MG/">boosted fundraising for refugees</a> 100-fold.</p> <h2>A more thoughtful process</h2> <p>Next time you pull out your smartphone to make an image, don’t just “<a href="https://www.digitalphotomentor.com/do-you-wait-for-the-decisive-moment-or-do-you-spray-and-pray/">spray and pray</a>”. Try to pre-visualise the story you want to tell and wait for the elements to line up into place.</p> <p>Being aware of aesthetic and ethical considerations alongisde technical ones and emotional resonance can all help engage viewers and lead to more standout imagery.</p> <p>To challenge yourself further, consider taking your phone off full-auto mode and play with camera settings to see how they impact the resulting photos.<!-- Below is The Conversation's page counter tag. Please DO NOT REMOVE. --><img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/229011/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /><!-- End of code.

Millions of phones at risk of being cut off from calling triple-0

<p>Over a million Aussies may be unable to contact triple-0 as two major telcos cut their 3G networks. </p> <p>Telstra's network will be closed on June 30 this year followed by Optus, which will shut their 3G network in September.</p> <p>While most late model phones are now serviced by either 4G or 5G networks, there are many devices that still rely on 3G. </p> <p>Approximately 113,000 Telstra customers have not upgraded their 3G handsets, while Optus have not disclosed a figure.</p> <p>The greater concerns lie for older 4G-enabled handsets that may not be able to call triple-0 once the 3G networks are switched off, because of the way those phones are configured.</p> <p>In March, Communications Minister Michelle Rowland was informed that 740,000 Australians were in that category.  </p> <p>A month later, that figure was revised to over a million. </p> <p>"I welcome the industry’s first report to government but am concerned around their disclosure of around one million potentially impacted consumers,” the minister said. </p> <p>“I am considering the detail provided and next steps, and the government will have more to say about the 3G switchover soon.”</p> <p>She also said that they were open to delaying the switchover  "if warranted in the public interest”.</p> <p>“Options exist under law for the government to consider proposals to delay the planned switchover, subject to consultation and procedural processes,” she said.</p> <p>Telstra has informed customers about what to do if they are affected, and how they could check. </p> <p>“If your mobile device doesn’t have Voice over LTE (VoLTE) technology, even if it uses 4G data, it will not be able to make voice calls on our network after 30 June 2024,” they informed their customers. </p> <p>“Not all VoLTE enabled devices support emergency VoLTE calling, meaning they will not be able to make an emergency call to triple-0 once 3G closes." </p> <p>“Without taking the recommended action you won’t be able to connect to a network after 30 June 2024,” they warned. </p> <p>Customers who are worried that they might be impacted, are encouraged to text 3 to the number 3498, so that the telco can inform the customer on their connection status.</p> <p>Optus have also encouraged customers to contact them if they think they may be affected. </p> <p><em>Image: Getty</em></p>

Detection dogs to lead search for Samantha Murphy's body

<p>Detectives have launched a <a href="https://www.oversixty.com.au/finance/legal/new-update-in-search-for-samantha-murphy-s-body" target="_blank" rel="noopener">fresh search</a> for Samantha Murphy's body, but after spending eight hours on Wednesday trying to locate her remains in Buninyong to no avail, they are trying a different approach. </p> <p>Technology detection dogs will assist detectives in their search on Thursday, at a new site that police have not specified, with the intention of trying to track her phone or watch. </p> <p>“We’ll be going to a different location but we will also use assistance from the Australian Federal Police today in technical detection dogs,” Chief Commissioner Shane Patton told <em>ABC Radio</em>. </p> <p>“We don’t have the capacity — we are trying to get that capability — to run a dog that can detect a SIM from a mobile phone and that type of thing.</p> <p>“We still haven’t recovered her phone and her watch. We’ll use all those specialist skills.”</p> <p>He also added that the "intelligence" they received, which sparked this fresh search did not come from interviews with accused murderer, Patrick Orren Stephenson. </p> <p>“We are doing everything we can to try and find Samantha Murphy’s body. We weren’t successful yesterday but we will continue to do everything we can,” Chief Commissioner Patton said. </p> <p>In another statement, Victoria police also said that the search on Thursday is not a "full-scale targeted search". </p> <p>"This is not a full-scale targeted search as took place yesterday in Buninyong with a range of specialist resources," they said. </p> <p>"Detectives from the Missing Persons squad have been based in Ballarat for over a month and regularly undertake a range of enquiries and small scale searches as part of the current investigation." </p> <p>The accused murderer, who is the <a href="https://www.oversixty.com.au/finance/legal/everything-we-know-about-samantha-murphy-s-accused-killer" target="_blank" rel="noopener">son of former AFL player</a> Orren Stephenson, was arrested and charged on March 6, and was refused bail at Ballarat Magistrate’s Court.</p> <p>He will next face court on August 8.</p> <p><em>Images: Nine News</em></p> <p> </p>

Leap of imagination: how February 29 reminds us of our mysterious relationship with time and space

<p><em><a href="https://theconversation.com/profiles/emily-ohara-874665">Emily O'Hara</a>, <a href="https://theconversation.com/institutions/auckland-university-of-technology-1137">Auckland University of Technology</a></em></p> <p>If you find it intriguing that February 28 will be followed this week by February 29, rather than March 1 as it usually is, spare a thought for those alive in 1582. Back then, Thursday October 4 was followed by Friday October 15.</p> <p>Ten whole days were snatched from the present when Pope Gregory XIII issued a papal bull to “restore” the calendar from discrepancies that had crept into the Julian calendar, introduced by Julius Caesar in 45 BCE.</p> <p>The new Gregorian calendar returned the northern hemisphere’s vernal equinox to its “proper” place, around March 21. (The equinox is when the Earth’s axis is tilted neither toward nor away from the sun, and is used to determine the date of Easter.)</p> <p>The Julian calendar had observed a leap year every four years, but this meant time had drifted out of alignment with the dates of celestial events and astronomical seasons.</p> <p>In the Gregorian calendar, leap days were added only to years that were a multiple of four – like 2024 – with an exception for years that were evenly divisible by 100, but not 400 – like 1700.</p> <p>Simply put, leap days exist because it doesn’t take a neat 365 days for Earth to orbit the Sun. It takes 365.2422 days. Tracking the movement of celestial objects through space in an orderly pattern doesn’t quite work, which is why we have February – time’s great mop.</p> <h2>Time and space</h2> <p>This is just part of the history of how February – the shortest month, and originally the last month in the Roman calendar – came to have the job of absorbing those inconsistencies in the temporal calculations of the world’s most commonly used calendar.</p> <p>There is plenty of <a href="https://theconversation.com/leap-day-fixing-the-faults-in-our-stars-54032">science</a>, <a href="https://theconversation.com/explainer-the-science-behind-leap-years-and-how-they-work-54788">maths</a> and <a href="https://theconversation.com/how-a-seasonal-snarl-up-in-the-mid-1500s-gave-us-our-strange-rules-for-leap-years-132659">astrophysics</a> explaining the relationship between time and the planet we live on. But I like to think leap years and days offer something even more interesting to consider: why do we have calendars anyway?</p> <p>And what have they got to do with how we understand the wonder and strangeness of our existence in the universe? Because calendars tell a story, not just about time, but also about space.</p> <p>Our reckoning of time on Earth is through our spatial relationship to the Sun, Moon and stars. Time, and its place in our lives, sits somewhere between the scientific, the celestial and the spiritual.</p> <p>It is <a href="https://shop.whitechapelgallery.org/products/time">notoriously slippery, subjective and experiential</a>. It is also marked, tracked and determined in myriad ways across different cultures, from tropical to solar to <a href="https://www.stuff.co.nz/pou-tiaki/300062097/matariki-and-the-maramataka-the-mori-lunar-calendar">lunar</a> calendars.</p> <p>It is the Sun that measures a day and gives us our first reference point for understanding time. But it is the <a href="https://librarysearch.aut.ac.nz/vufind/Record/1145999?sid=25214690">Moon</a>, as a major celestial body, that extends our perception of time. By stretching a span of one day into something longer, it offers us a chance for philosophical reflection.</p> <p>The Sun (or its effect at least) is either present or not present. The Moon, however, goes through phases of transformation. It appears and disappears, changing shape and hinting that one night is not exactly like the one before or after.</p> <p>The Moon also has a distinct rhythm that can be tracked and understood as a pattern, giving us another sense of duration. Time is just that – overlapping durations: instants, seconds, minutes, hours, days, weeks, months, years, decades, lifetimes, centuries, ages.</p> <h2>The elusive Moon</h2> <p>It is almost impossible to imagine how time might feel in the absence of all the tools and gadgets we use to track, control and corral it. But it’s also hard to know what we might do in the absence of time as a unit of productivity – a measurable, dispensable resource.</p> <p>The closest we might come is simply to imagine what life might feel like in the absence of the Moon. Each day would rise and fall, in a rhythm of its own, but without visible reference to anything else. Just endless shifts from light to dark.</p> <p>Nights would be almost completely dark without the light of the Moon. Only stars at a much further distance would puncture the inky sky. The world around us would change – trees would grow, mammals would age and die, land masses would shift and change – but all would happen in an endless cycle of sunrise to sunset.</p> <p>The light from the Sun takes <a href="https://www.skyatnightmagazine.com/space-science/how-take-light-from-sun-reach-earth">eight minutes</a> to reach Earth, so the sunlight we see is always eight minutes in the past.</p> <p>I remember sitting outside when I first learned this, and wondering what the temporal delay might be between me and other objects: a plum tree, trees at the end of the street, hills in the distance, light on the horizon when looking out over the ocean, stars in the night sky.</p> <p>Moonlight, for reference, takes about <a href="https://www.pbs.org/seeinginthedark/astronomy-topics/light-as-a-cosmic-time-machine.html">1.3 seconds</a> to get to Earth. Light always travels at the same speed, it is entirely constant. The differing duration between how long it takes for sunlight or moonlight to reach the Earth is determined by the space in between.</p> <p>Time on the other hand, is anything but constant. There are countless ways we characterise it. The mere fact we have so many calendars and ways of describing perceptual time hints at our inability to pin it down.</p> <p>Calendars give us the impression we can, and have, made time predictable and understandable. Leap years, days and seconds serve as a periodic reminder that we haven’t.<!-- Below is The Conversation's page counter tag.

8 places you should never keep your phone

<p><strong>In your pocket</strong></p> <p>Keeping your phone in your pocket seems logical, but you could be doing more harm than good. According to Dr Lilly Friedman, this is actually the worst place to store your phone. “When phones are on, connected to a wireless network, and placed in a pocket, the radiation is two to seven times higher than if it were placed in a purse or holster,” she says.</p> <p>There is a correlation between radiation from a mobile phone and tumour growth, she adds. Plus, radiation can change the structure of DNA and affect male fertility, according to Dr Friedman. The World Health Organization’s International Agency for Research on Cancer also found that mobile phone radiation is additionally carcinogenic to humans. Merely sitting on your phone could cause health issues such as sciatica or back problems.</p> <p><strong>In your bra</strong></p> <p>Some research and case studies show that keeping your phone in your bra could be linked to breast cancer due to the radiations and vibrations from the phone. That said, there is not enough evidence to establish a definite relationship between the two. Still, keeping your phone in your bra, especially a sports bra, is a bad idea due to the skin-irritating bacteria it could harbour, Muscle &amp; Fitness reports.</p> <p><strong>In your bed or under your pillow</strong></p> <p>Sleeping with your phone is a bad idea for a few reasons. First, keeping your phone under your pillow could build up heat and present a potential fire hazard, especially if your phone is charging or has a defect. It’s also known that the LED light from phone screens can disrupt melatonin production and circadian rhythms, hurting your sleep quality, according to the National Sleep Foundation.</p> <p>And, of course, there’s also radiation to consider. The amounts of radio frequency radiation mobile phones give off are the same ones emitted from microwaves. There is also concern about the safety of mobile phone use with respect to cancer and brain tumours, per the American Cancer Society.</p> <p><strong>Plugged in</strong></p> <p>Keeping your phone plugged in when it has a full battery causes damage to the battery itself, according to pcmag.com. It’s not that your phone ‘overloads’ with power, but heat build-ups from stacking things on top of your phone or keeping it under your pillow, making your phone hotter and damaging your battery.</p> <p><strong>Close to your face</strong></p> <p>Keeping your phone close to your face means bacteria transfers to and from your phone, making your skin and phone dirtier. This combination leads to more acne, skin irritation and even wrinkles, according to Allure. Try using ear pods instead to keep the surface of your phone at a distance from your face.</p> <p><strong>In your glovebox</strong></p> <p>Extreme temperatures are the worst conditions for your phone. So keeping your device in your car’s glovebox during the extremely hot or cold months of the year could lead to problems. According to Time, excess heat can cause everything from data loss or corruption to battery leakage. The cold weather presents just as many issues for your device. In cold temperatures, many smartphones shut off, have display problems, shortened battery life and in rare cases screen shattering.</p> <p><strong>On your beach towel </strong></p> <p>Notice a theme here? The extreme sun and heat at the beach is a recipe for phone disaster. Protect your device after you finish taking beautiful beach pictures. Hot and sunny conditions could, again, cause your phone to overheat – and getting sand in your phone won’t help either.</p> <p><strong>Anywhere in the bathroom</strong></p> <p>Although phones could arguably be the new newspaper, it’s not a good idea to take yours into the bathroom. Even if you keep your device on a counter or away from the toilet, anything within a metre of a flushing toilet could mean bacteria or viruses in the air end up on your phone, according to a study published in Applied and Environmental Microbiology.</p> <p>“The detection of bacteria and viruses falling out onto surfaces in bathrooms after flushing indicated that they remain airborne long enough to settle on surfaces throughout the bathroom,” wrote the study authors.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/healthsmart/8-places-you-should-never-keep-your-phone" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Why do I get so much spam and unwanted email in my inbox? And how can I get rid of it?

<p><em><a href="https://theconversation.com/profiles/kayleen-manwaring-8735">Kayleen Manwaring</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>Spam might not have brought an end to the internet or email, as some dire predictions <a href="https://www.zdnet.com/article/why-spam-could-destroy-the-internet/">in the early 2000s</a> claimed it could – but it’s still a massive pain.</p> <p>Despite all the spam being removed by spam-filtering technologies, most people still receive spam every day. How do these messages end up flooding our inboxes? And are there any legal consequences for the senders?</p> <h2>What is spam?</h2> <p>The Organisation for Economic Co-operation and Development (OECD) noted in 2004 “there does not appear to be a widely agreed and workable definition for spam” across jurisdictions – and this remains true today.</p> <p>That said, “spam” generally <a href="https://www.oecd-ilibrary.org/docserver/232784860063.pdf?expires=1693541947&amp;id=id&amp;accname=ocid177499&amp;checksum=D0C5BDAC49951DF353618B8E38483253">refers to</a> unsolicited electronic messages. These are often sent in bulk and frequently advertise goods or services. It also includes scamming and phishing messages, according to the OECD.</p> <p>Most people think of spam in the form of emails or SMS messages. However, what we now call spam actually predates the internet. In 1854, a spam telegram was sent to British politicians advertising the opening hours of dentists who <a href="https://www.theguardian.com/technology/2013/aug/09/why-spammers-are-winning-junk-mail">sold tooth-whitening powder</a>.</p> <p>The first spam email came more than 100 years later. It was reportedly sent to 600 people on May 3 1978 <a href="https://web.archive.org/web/20080628205216/http://www.latimes.com/technology/la-fi-spam11may11001420,1,5168218,full.story">through ARPAnet</a> – a precursor to the modern internet.</p> <p>As for how much spam is out there, the figures vary, possibly due to the various <a href="https://www.spamhaus.org/consumer/definition/">definitions of “spam”</a>. One source reports the average number of spam emails sent daily in 2022 was about <a href="https://dataprot.net/statistics/spam-statistics/">122.33 billion</a> (which would mean more than half of all emails were spam). As for text messages, another source reports a daily average of 1.6 billion <a href="https://thesmallbusinessblog.net/spam-text-statistics/">spam texts</a>.</p> <h2>Where do spammers get my details?</h2> <p>Each time you enter your email address or phone number into an e-commerce website, you may be handing it to spammers.</p> <p>But sometimes you may even receive spam from entities you don’t recognise. That’s because businesses will often transfer customers’ contact information to related companies, or sell their data to third parties such as data brokers.</p> <p>Australia’s Privacy Act 1988 somewhat limits the transfer of personal information to third parties. However, these laws <a href="https://theconversation.com/accc-says-consumers-need-more-choices-about-what-online-marketplaces-are-doing-with-their-data-182134">are weak</a> – and <a href="http://handle.unsw.edu.au/1959.4/unsworks_75600">weakly enforced</a>.</p> <p>Some entities also use “address-harvesting” software to search the internet for electronic addresses that are captured in a database. The collector then uses these addresses directly, or sells them to others looking to send spam.</p> <p>Many jurisdictions (including <a href="http://www8.austlii.edu.au/cgi-bin/viewdoc/au/legis/cth/consol_act/sa200366/s19.html">Australia</a>) prohibit these harvesting activities, but they are still <a href="https://www.projecthoneypot.org/statistics.php">common</a>.</p> <h2>Is spamming against the law?</h2> <p>Australia has had legislation regulating spam messaging since 2003. But the <a href="https://www.legislation.gov.au/Details/C2016C00614">Spam Act</a> surprisingly does not define the word “spam”. It tackles spam by prohibiting the sending of <a href="http://www8.austlii.edu.au/cgi-bin/viewdoc/au/legis/cth/consol_act/sa200366/s15.html">unsolicited commercial electronic messages</a> containing offers, ads or other promotions of goods, services or land.</p> <p>However, if the receiver <a href="http://www8.austlii.edu.au/cgi-bin/viewdoc/au/legis/cth/consol_act/sa200366/sch2.html">consented</a> to these types of messages, the prohibition does not apply. When you buy goods or services from a company, you will often see a request to click on a “yes” button to receive marketing promotions. Doing so means you have consented.</p> <p>On the other hand, if your phone or inbox are hit by commercial messages you haven’t agreed to receive, that is a breach of the <a href="https://austlii.edu.au/cgi-bin/viewdb/au/legis/cth/consol_act/sa200366/">Spam Act</a> by the sender. If you originally signed up to receive the messages, but then unsubscribed and the messages kept coming after <a href="https://austlii.edu.au/cgi-bin/viewdoc/au/legis/cth/consol_act/sa200366/sch2.html">five business days</a>, that is also illegal. Senders must also include a <a href="https://austlii.edu.au/cgi-bin/viewdoc/au/legis/cth/consol_act/sa200366/s18.html">functioning unsubscribe facility</a> in every commercial message they send.</p> <p>Spammers can be penalised for breaches of the Spam Act. In the past few months alone, <a href="https://www.acma.gov.au/articles/2023-06/commonwealth-bank-penalised-355-million-spam-breaches">Commonwealth Bank</a>, <a href="https://www.acma.gov.au/articles/2023-08/doordash-penalised-2-million-spam-breaches">DoorDash</a> and <a href="https://www.acma.gov.au/articles/2023-06/mycar-tyre-auto-penalised-1m-spam-breaches">mycar Tyre &amp; Auto</a> were fined more than A$6 million in total for breaches.</p> <p>However, most spam comes from outside Australia where the laws aren’t the same. In the United States spam is legal under the <a href="https://www.ftc.gov/business-guidance/resources/can-spam-act-compliance-guide-business">CAN-SPAM Act</a> until you opt out. Unsurprisingly, the US <a href="https://talosintelligence.com/reputation_center/email_rep#spam-country-senders">tops the list</a> of countries where the most spam originates.</p> <p>Although spam sent to Australia from overseas <a href="https://austlii.edu.au/cgi-bin/viewdoc/au/legis/cth/consol_act/sa200366/s16.html">can still breach</a> the Spam Act – and the Australian Communications and Media Authority (ACMA) co-operates with overseas regulators – overseas enforcement actions are difficult and expensive, especially if the spammer has disguised their true identity and location.</p> <p>It’s worth noting that messages from political parties, registered charities and government bodies aren’t prohibited – nor are messages from educational institutions to students and former students. So while you might consider these messages as “spam”, they can legally be <a href="http://www8.austlii.edu.au/cgi-bin/viewdoc/au/legis/cth/consol_act/sa200366/sch1.html">sent freely without consent</a>. Factual messages (without marketing content) from businesses are also legal as long as they include accurate sender details and contact information.</p> <p>Moreover, the Spam Act generally only covers spam sent via email, SMS/MMS or instant messaging services, such as WhatsApp. Voice calls and faxes aren’t covered (although you can use the <a href="https://www.donotcall.gov.au/">Do Not Call Register</a> to block some commercial calls).</p> <h2>Staying safe from spam (and cyberattacks)</h2> <p>Spam isn’t only annoying, it can also be dangerous. Spam messages can contain indecent images, scams and <a href="https://www.cyber.gov.au/learn-basics/explore-basics/watch-out-threats/phishing-emails-and-texts">phishing attempts</a>. Some have <a href="https://www.cyber.gov.au/threats/types-threats/malware">malware</a> (malicious software) designed to break into computer networks and cause harm, such as by stealing data or money, or shutting down systems.</p> <p>The <a href="https://www.cyber.gov.au/protect-yourself/securing-your-email/email-security/protect-yourself-malicious-email">Australian Cyber Security Centre</a> and <a href="https://www.acma.gov.au/dealing-with-spam">ACMA</a> provide useful tips for reducing the spam you get and your risk of being hit by cyberattacks. They suggest to:</p> <ol> <li> <p>use a spam filter and block spammers – email and telecommunications providers often supply useful tools as part of their services</p> </li> <li> <p>unsubscribe from any emails you no longer want to receive – even if you originally agreed to receive them</p> </li> <li> <p>remove as much of your contact details from websites as you can and always restrict the sharing of your personal information (such as name, birth date, email address and mobile number) when you can – beware of pre-ticked boxes asking for your consent to receive marketing emails</p> </li> <li> <p>install cybersecurity updates for your devices and software as you get them</p> </li> <li> <p>always think twice about opening emails or clicking on links, especially for messages promising rewards or asking for personal information – if it looks too good to be true, it probably is</p> </li> <li> <p>use <a href="https://theconversation.com/what-is-multi-factor-authentication-and-how-should-i-be-using-it-191591">multi-factor authentication</a> to access online services so even if a scam compromises your login details, it will still be difficult for hackers to break into your accounts</p> </li> <li> <p>report spam to your email and telecommunications providers, and to <a href="https://www.acma.gov.au/dealing-with-spam#complain-or-forward-spam-to-the-acma">ACMA</a>. <!-- Below is The Conversation's page counter tag.

Why you need to stop charging your phone overnight

<p><strong>You charge your phone all night </strong></p> <p>Waking up to a fully charged phone may seem like a great way to start the day, but leaving your device plugged in overnight is a bad idea. When a phone has reached 100 per cent charge, it will continue to get trickle charges to keep it topped up at 100 percent.</p> <p>These extra charges keep the battery working non-stop. In fact, it’s better not to fully charge lithium-ion batteries because high voltage stresses the battery and wears it out over time, according to technology company Cadex.</p> <p><strong>You use vibrations for notifications</strong></p> <p>Your phone, like any other tool or device, ages and loses effectiveness the more you use it, says David Steele, the Director of Business Development for EverydayPhone. So little extras, like vibrating notifications, are habits that make your phone’s job harder. </p> <p>“The issue with these habits essentially boils down to having your phone constantly running at full capacity when it’s unnecessary,” Steele says. “Just like us, a phone needs a break to avoid burning out.”</p> <p><strong>You keep apps open that you're not using</strong></p> <p>Unused apps can eat up the battery life of smartphones, according to Andrew Moore-Crispin, the Director of Content at Ting Mobile. “If you open an app once and never use it again, the app might still run in the background,” he says.</p> <p>Swiping out of apps you aren’t using or no longer need is an easy solution. Moore-Crispin says doing so extends the battery life of your phone while also freeing up valuable storage space, too.</p> <p><strong>You allow unnecessary permissions</strong></p> <p>Ride-sharing apps need your location to pick you up, but other apps might not need this permission. Moore-Crispin suggests you be picky about which apps you grant such permissions to and take away permissions you deem unnecessary.</p> <p><strong>You have one of these apps</strong></p> <p>The apps that drain your battery the most are Snapchat, Google Maps, Netflix, Amazon, and Facebook, according to AdWeek. The Guardian found that uninstalling the Facebook mobile app from Android phones saves people up to 20 percent of their battery life.</p> <p>If you also get rid of the FB Messenger app, other app load times could speed up by 15 per cent, per the Guardian. The reason Facebook particularly kills battery life is because it keeps running in the background – even when you’re not using it, Business Insider reports.</p> <p><strong>Your screen is always extremely bright </strong></p> <p>Gone are the days of tiny phone screens, but before you give the thumbs up emoji, understand how the bigger screens of today can be a phone battery’s worst enemy, according to Moore-Crispin. Make sure you turn on adaptive brightness in the display menu.</p> <p>This change means your phone will automatically adjust the screen brightness to match your environment. As a bonus, set the brightness level to the lowest possible and lower your screen’s timeout, which is what determines how long it stays lit before fading when it goes idle.</p> <p><strong>You keep your phone out at the beach</strong></p> <p>Extreme heat or extreme cold temperatures and other weather conditions can shorten the life of your phone. According to Time, excess heat can cause everything from data loss or corruption to battery leakage. Cold weather presents just as many issues. In cold temperatures, some smartphones shut off, have display problems, or run out of battery; in rare cases screens may shatter.</p> <p><strong>You keep your phone in your bed or under your pillow </strong></p> <p>Tucking your phone under your pillow when you sleep is another way to shorten its life, thanks to heat build-up.</p> <p><strong>You don't keep your software up to date</strong></p> <p>utting off device updates does more harm than good for your phone. iPhone and Android makers push updates to make your user experience better and so that your phone functions properly. These updates come with extra benefits, too. In fact, if your device has a weak battery or other issues, these software updates could remedy them, Popular Science reports. Make sure to keep up with app-specific updates as well.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/home-tipsscience-technology/why-you-need-to-stop-charging-your-phone-overnight" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Return and Earn is a great way to recycle

<p>When you recycle your eligible bottles and cans through Return and Earn, the material that is used to make the bottles and cans stay in use for as long as possible and are turned into new products, rather than ending up in landfill or polluting waterways.</p> <p>The scheme has already more than halved the number of drink containers littering our parks, waterways, or ending up in landfill compared to before the scheme was launched in December 2017.</p> <p><strong>What happens to containers returned through Return and Earn?</strong></p> <p>Have you ever wondered what happens to the containers once they are returned through the scheme?</p> <p>All containers returned through Return and Earn are recycled. The containers are picked up from the return points and trucked to a sorting facility where the containers are processed depending on the material type. Cans are crushed and baled into a giant cube, glass bottles are crushed into small particles called cullet; and plastic bottles are sorted by type and colour and shredded into smaller flakes before being turned into pellets.</p> <p><img class="alignnone size-full wp-image-68727" src="https://www.readersdigest.com.au/wp-content/uploads/2023/08/crushed-cans-770.jpg" alt="" width="770" height="500" /></p> <p>The giant cubes of Aluminium cans are melted, rolled into sheets, and sent to manufacturers to be turned into new cans or other products – some even go to make up aeroplane parts!</p> <p>Glass cullet is melted and mixed with raw materials before being blown into a new glass bottle and sent to drink companies.</p> <p>The plastic pellets are melted down, moulded and blown into new plastic bottles, ready to be bought be retailers.</p> <p>The new bottles and cans made from the recycled materials are filled by the beverage companies, labelled, capped, and ready to be consumed.</p> <p>By using the recycled material from Return and Earn, we save water, energy, and landfill, as well as reducing the carbon emissions that would be used if new raw materials were used instead. This conservation contributes to a more sustainable and efficient economy.</p> <p><strong>Keeping materials in Australia</strong></p> <p>The purity and quality of the material from Return and Earn plays a crucial role in establishing local recycling facilities so most of the key materials stay in Australia.  A key milestone was the opening of the Circular Plastics Australia plant in Albury, NSW, in March 2022. This state-of-the-art PET plastic recycling facility is a joint venture between waste industry and beverage industry partners and is the largest of its kind in Australia.</p> <p>The facility reprocesses 100% of the PET (one of the materials that make up plastic containers) collected through the Return and Earn network of over 600 return points and uses the materials to remake new bottles and other food-grade plastic packaging.</p> <p>All glass collected through the Return and Earn network is also being reprocessed in Australia and contributes to the growing demand of locally sourced glass to use in making new bottles and other products.</p> <p>Having facilities in Australia means that the cycle of making a new container from the recycled material is fast. Plastic bottles can be back on the shelf in as little as six weeks and glass bottles in four weeks. Now that’s recycling at its best.</p> <p><img class="alignnone size-full wp-image-68725" src="https://www.readersdigest.com.au/wp-content/uploads/2023/08/what-happens-when-you-return-and-earn-journey-image_770.jpg" alt="" width="770" height="846" /></p> <p><strong>Do you recycle?</strong></p> <p>It’s easier than ever to recycle your empty containers through Return and Earn.

Done with Barbie? How to reuse or recycle old dolls

<p>Bright pink clothing has been a hot item at a number of Brotherhood of St Laurence (BSL) op shops as movie-goers doll up to see Greta Gerwig’s <em>Barbie</em>.</p> <div class="copy"> <p>Kelly McMurray, an area store manager for BSL, says “a lot of 18 – 35 year old women have been coming in to get outfits for premier parties. </p> <p>“It’s been really fun helping people to find their outfits!”  </p> <p>The movie has set off a global Barbiecore mania, pinkifying everything and <a href="https://au.news.yahoo.com/barbie-movies-potential-500-million-haul-could-have-huge-implications-for-mattel-123756476.html" target="_blank" rel="noreferrer noopener">driving demand</a> for more plastic dolls and toy company merchandise.</p> <p>Even before the movie, the global population of Barbies was growing by <a href="https://cosmosmagazine.com/people/barbie-science/" target="_blank" rel="noreferrer noopener">around 100 new dolls every minute</a>. </p> <p>Which begs the question: what to do with all those dolls once the gloss of the movie ultimately wears off?</p> <p>For toys still in good condition, reusing them by donating to friends or op shops is an obvious first choice.</p> <p>“Our stores do receive a lot of toys every year,” McMurray says.</p> <p>“The peak of our toy donations would be in the New Year and the second week of every school holidays – when people have either been gifted new toys (after Christmas) and when they have had time to do a clean out – hence the second week of school holidays.” </p> <p>For those seeking a more sustainable supply of Barbie dolls, accessories or merchandise, McMurray suggests visiting one of the bigger BSL stores, as those tend to receive the bulk of toy donations.</p> <p>In Melbourne, the Deer Park op shop has two large sections dedicated to kids toys and clothes, while the Belmont store has been receiving – and selling – a lot of Barbie DVDs.</p> <p>When donating Barbies, or any kind of doll or toy, McMurray says people need to really consider if the toy is in a suitable condition, and isn’t missing any body parts. </p> <p>“A little wear and tear is ok. But if people have any doubts about it – best not to include it in their donations.”</p> <p>For those ‘weird Barbies’ past the point of no return, recycling is the next best option. </p> <p>Research by retailer Flora &amp; Fauna suggests Australians send <a href="https://giftguideonline.com.au/flora-fauna-launches-upcycled-toys-christmas-initiative/" target="_blank" rel="noreferrer noopener">26.8 million toys</a> to landfill every year.</p> <p>Plastic toys are considered harder to recycle than many regular household items, and can not be put in kerbside recycling bins.</p> <p><iframe title="Think Pink: The Science of Barbie" src="https://omny.fm/shows/huh-science-explained/think-pink-the-science-of-barbie/embed?in_playlist=podcast&amp;style=Cover" width="100%" height="180" frameborder="0"></iframe></p> <p>Global recycling company TerraCycle offers a toy recycling program for worn out and broken toys in partnership with department store Big W. It’s called ‘Toys for Joy’.</p> <p>Marina Antoniozzi, TerraCycle’s head of operations, says the initiative saw over 18 tonnes of old toys collected in the first year of trial operations in 2021. </p> <p>The program has now collected well over 160 tonnes of toys, she says.</p> <p>“The majority of toys are not kerbside recyclable due to the complex nature of their composition. Toys are frequently made up of several materials including different types of plastics and metals, which means they need to be manually sorted and separated,” Antoniozzi says.</p> <p>The recycling company partners with toy brands and retailers because the cost to collect and process the material is usually more than the value of raw material produced through the recycling process.</p> <p>In Barbie’s case, the doll is made up of a <a href="https://cosmosmagazine.com/people/culture/plastic-artefact-what-is-barbie-even-made-of/" target="_blank" rel="noreferrer noopener">complex mix of different types of plastics</a>. </p> <p>According to a <a href="https://www.mdpi.com/2073-4360/14/20/4287" target="_blank" rel="noreferrer noopener">study by Italian researchers</a> early dolls made between 1959 and 1976 comprised a complex mix of different <a href="https://cosmosmagazine.com/science/explainer-what-is-a-polymer/" target="_blank" rel="noreferrer noopener">polymers</a>: polyvinyl chloride faces and legs; hair from polyvinylidene dichloride; and torsos made from low-density polyethylene. </p> <p>More <a href="http://www.designlife-cycle.com/barbie-dolls" target="_blank" rel="noreferrer noopener">modern dolls</a> have arms of ethylene-vinyl acetate (also used in thongs, and frozen food packaging), torsos of acrylonitrile-butadiene-styrene (also found in Lego), legs from polypropylene, and heads made of hard vinyl (like the kind used in vinyl records). </p> <p>Once collected, the toys sent to TerraCycle for recycling are checked in at TerraCycle’s Materials Recovery Facility where they are manually sorted, separated into individual material streams and prepared for processing.</p> <p>Antoniozzi says that in Australia, TerraCycle processes Barbie dolls and accessories along with other hard plastic toys. These are sent to recycling facilities to be shredded and cleaned. </p> <p>Residual metals are removed using magnets in a process called eddy current separation. </p> <p>The plastics are then sorted into different types using technologies like near infrared, a spectroscopy technique used for analysing and differentiating between polymers.</p> <p>Afterwards, the separated, shredded plastics go through a melting and extrusion process producing recycled plastic pellets, used by manufacturers to make a variety of products.</p> <p>So, when Barbie goes to the recycling plant, she will ultimately be sorted, shredded, melted and turned into plastic pellets.</p> <p>Antoniozzi says donating toys is a good first option. </p> <p>“But if your Barbie is genuinely beyond repair, then you can take her, Ken, Sandy, as well as all her horses, buses, apartments and accessories along to your local BIG W store and give her a second life through the Toys for Joy recycling program,” she says.</p> <p>“Who knows… she may come back to you as a flower pot.” </p> <p><em>Image credits: Shutterstock</em></p> <p><em><!-- Start of tracking content syndication.

The $500 million ATO fraud highlights flaws in the myGov ID system. Here’s how to keep your data safe

<p><em><a href="https://theconversation.com/profiles/rob-nicholls-91073">Rob Nicholls</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>The Australian Tax Office (ATO) paid out more than half a billion dollars to cyber criminals between July 2021 and February 2023, according to an <a href="https://www.abc.net.au/news/2023-07-26/ato-reveals-cost-of-mygov-tax-identity-crime-fraud/102632572">ABC report</a>.</p> <p>Most of the payments were for small amounts (less than A$5,000) and were not flagged by the ATO’s own monitoring systems.</p> <p>The fraudsters exploited a weakness in the identification system used by the myGov online portal to redirect other people’s tax refunds to their own bank accounts.</p> <p>The good news is there’s plenty the federal government can do to crack down on this kind of fraud – and that you can do to keep your own payments secure.</p> <h2>How these scams work</h2> <p>Setting up a myGov account or a myGov ID requires proof of identity in the form of “<a href="https://www.afp.gov.au/sites/default/files/PDF/NPC-100PointChecklist-18042019.pdf">100 points of ID</a>”. It usually means either a passport and a driver’s licence or a driver’s licence, a Medicare card, and a bank statement.</p> <p>Once a myGov account is created, linking it to your tax records requires two of the following: an ATO assessment, bank account details, a payslip, a Centrelink payment, or a super account.</p> <p>These documents were precisely the ones targeted in three large data breaches in the past year: at <a href="https://theconversation.com/what-does-the-optus-data-breach-mean-for-you-and-how-can-you-protect-yourself-a-step-by-step-guide-191332">Optus</a>, at <a href="https://theconversation.com/medibank-hackers-are-now-releasing-stolen-data-on-the-dark-web-if-youre-affected-heres-what-you-need-to-know-194340">Medibank</a>, and at <a href="https://asic.gov.au/about-asic/news-centre/news-items/guidance-for-consumers-impacted-by-the-latitude-financial-services-data-breach/">Latitude Financial</a>.</p> <p>In this scam, the cyber criminal creates a fake myGov account using the stolen documents. If they can also get enough information to link to the ATO or your Tax File Number, they can then change bank account details to have your tax rebate paid to their account.</p> <p>It is a sadly simple scam.</p> <h2>How government can improve</h2> <p>One of the issues here is quite astounding. The ATO knows where salaries are paid, via the “<a href="https://www.ato.gov.au/business/single-touch-payroll/what-is-stp-/">single touch</a>” payroll system. This ensures salaries, tax and superannuation contributions are all paid at once.</p> <p>Most people who have received a tax refund will have provided bank account details where that payment can be made. Indeed, many people use precisely those bank account details to identify themselves to myGov.</p> <p>At present, those bank details can be changed within myGov without any further ado. If the ATO simply checked with the individual via another channel when bank account details are changed, this fraud could be prevented. It might be sensible to check with the individual’s employer as well.</p> <p>Part of the problem is the ATO has not been very transparent about the risks. If these risks were clearly set out, then calls for changes to ATO procedures would have been loud and clear from the cyber security community.</p> <p>The ATO is usually good at identifying when a cyber security incident may lead to fraud. For example, when the recruitment software company <a href="https://www.abc.net.au/news/2018-06-06/australian-data-may-be-compromised-in-pageup-security-breach/9840048?itm_campaign=newsapp">PageUp was hacked in 2018</a>, the ATO required people who may have been affected to reconfirm their identities. This was done without public commentary and represents sound practice.</p> <p>Sadly, the millions of records stolen in the Optus, Medibank and Latitude Financial breaches have not led to a similar level of vigilance.</p> <p>Another action the ATO could take would be to check when a single set of bank account details is associated with more than one myGov account.</p> <p>A national digital identity would also help. However, this system has been in development for years, is not universally popular, and may well be <a href="https://www.themandarin.com.au/226280-gallagher-warns-community-support-for-digital-identity-not-ubiquitous/">delayed</a> until after the federal election due in 2024.</p> <h2>Protecting yourself</h2> <p>The most important thing to do is make sure the ATO does not use a bank account number other than yours. As long as the ATO only has your bank account number to transfer your tax rebate, this scam does not work.</p> <p>It also helps to protect your Tax File Number. There are only four groups that ever need this number.</p> <p>The first is the ATO itself. The second is your employer. However, remember you do not need to give your TFN to a prospective employer, and your employer only needs your TFN <em>after</em> you have started work.</p> <p>Your super fund and your bank may ask for your TFN. However, providing your TFN to your super fund or bank is optional – it just makes things easier, as otherwise they will withhold tax which you will need to claim back later.</p> <p>Of course, all the usual data safety issues still apply. Don’t share your driver’s licence details without good reason. Take similar care with your passport. Your Medicare card is for health services and does not need to be shared widely.</p> <p>Don’t open emails from people you do not know. Never click links in messages unless you are sure they are safe. Most importantly, know your bank will not send you emails containing links, nor will the ATO.<!-- Below is The Conversation's page counter tag.

Why am I online? Research shows it’s often about managing emotions

<p><em><a href="https://theconversation.com/profiles/wally-smith-1450210">Wally Smith</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> and <a href="https://theconversation.com/profiles/greg-wadley-203663">Greg Wadley</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p>Most of us <a href="https://wearesocial.com/au/blog/2022/02/digital-2022-australia-online-like-never-before/">go online</a> multiple times a day. About half of 18–29 year olds surveyed in a 2021 <a href="https://www.pewresearch.org/short-reads/2021/03/26/about-three-in-ten-u-s-adults-say-they-are-almost-constantly-online/">Pew Research Study</a> said they are “almost constantly” connected.</p> <p>How are we to make sense of this significant digital dimension of modern life?</p> <p>Many questions have rightly been asked about its broader consequences for society and the economy. But there remains a simpler question about what motivates people across a range of ages, occupations and cultures to be so absorbed in digital connection.</p> <p>And we can turn this question on ourselves: <em>why am I online?</em></p> <h2>What are we doing when we go online?</h2> <p>As the American sociologist Erving Goffman <a href="https://www.nytimes.com/1975/02/16/archives/frame-analysis.html">pointed out</a>, asking “What is it that’s going on here?” about human behaviour can yield answers framed at different levels. These range from our superficial motives to a deeper understanding of what we are “really” doing.</p> <p>Sometimes we might be content to explain our online behaviour in purely practical terms, like checking traffic routes or paying a bill. Other times we might struggle to articulate our reasons for going or remaining online.</p> <p>Why are we continually looking at our phones or computers, when we could be getting on with physical tasks, or exercising, or meditating, or engaging more fully with the people who are physically around us?</p> <h2>The ever-present need to manage our emotions</h2> <p>As researchers of human-computer interaction, we are exploring answers in terms of the ever-present need to manage our emotions. Psychologists refer to this activity as <a href="https://www.guilford.com/books/Handbook-of-Emotion-Regulation/James-Gross/9781462520732">emotion regulation</a>.</p> <p>Theories of the nature and function of emotions are complex and contested. However, it is safe to say they are expressions of felt needs and motivations that arise in us through some fusion of physiology and culture.</p> <p>During a typical day, we often feel a need to <a href="https://journals.sagepub.com/doi/abs/10.1037/1089-2680.2.3.271">alter our emotional state</a>. We may wish to feel more serious about a competitive task or more sad at a funeral. Perhaps we would like to be less sad about events of the past, less angry when meeting an errant family member, or more angry about something we know in our heart is wrong.</p> <figure><iframe src="https://www.youtube.com/embed/PQkNb4CLjJ8?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Digital emotion regulation is becoming increasingly common in our everyday lives.</span></figcaption></figure> <p>One way to understand our frequent immersions into online experience is to see them as acts within a broader scheme of managing such daily emotional demands. Indeed, in <a href="https://www.sciencedirect.com/science/article/abs/pii/S1071581922001732">earlier research</a> we found up to half of all smartphone use may be for the purpose of emotional regulation.</p> <h2>Digital technologies are becoming key tools of emotion regulation</h2> <p>Over the pandemic lockdowns of 2020–21 in Melbourne, Australia, we investigated how digital technologies are becoming <a href="https://dl.acm.org/doi/10.1145/3491102.3517573">key tools of emotion regulation</a>. We were surprised to find that people readily talked of their technology use in these emotion-managing terms.</p> <p>Occasionally, this involved specially designed apps, for mindfulness and so on. But more often people relied on mundane tools, such as using social media alongside Zoom to combat feelings of boredom or isolation, browsing for “retail therapy”, playing phone games to de-stress, and searching online to alleviate anxiety about world events.</p> <p>To some extent, these uses of digital technology can be seen as re-packaging <a href="https://www.tandfonline.com/doi/abs/10.1080/026999399379285">traditional methods</a> of emotion management, such as listening to music, strengthening social connections, or enjoying the company of adorable animals. Indeed, people in our study used digital technologies to enact familiar strategies, such as immersion in selected situations, seeking distractions, and reappraising what a situation means.</p> <p>However, we also found indications that digital tools are changing the intensity and nature of how we regulate emotions. They provide emotional resources that are <a href="https://en.wikipedia.org/wiki/Ubiquitous_computing">nearly always available</a>, and virtual situations can be accessed, juxtaposed and navigated more deftly than their physical counterparts.</p> <p>Some participants in our study described how they built what we called “emotional toolkits”. These are collections of digital resources ready to be deployed when needed, each for a particular emotional effect.</p> <h2>A new kind of digital emotional intelligence</h2> <p>None of this is to say emotion regulation is automatically and always a good thing. It can be a means of avoiding important and meaningful endeavours and it can itself become dysfunctional.</p> <p>In our study of a small sample of Melburnians, we found that although digital applications appeared to be generally effective in this role, they are volatile and can lead to <a href="https://www.theguardian.com/commentisfree/2020/sep/27/social-dilemma-media-facebook-twitter-society">unpredictable emotional outcomes</a>. A search for energising music or reassuring social contact, for example, can produce random or unwanted results.</p> <p>A new kind of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10187756/">digital emotional intelligence</a> might be needed to effectively navigate digital emotional landscapes.</p> <h2>An historic shift in everyday life</h2> <p>Returning to the question: <em>what am I doing online?</em> Emotion regulation may well be the part of the answer.</p> <p>You may be online for valid instrumental reasons. But equally, you are likely to be enacting your own strategies of <a href="https://cis.unimelb.edu.au/hci/projects/digitalemotionregulation">emotion regulation through digital means</a>.</p> <p>It is part of an historic shift playing out in how people negotiate the demands of everyday life. <!-- Below is The Conversation's page counter tag.

Facebook Messenger scams are on the rise – here’s how to protect yourself

<p><strong>Facebook Messenger scams prey on our vulnerabilities</strong></p> <p>Scams through Facebook’s Messenger platform are being reported at higher rates than ever before, according to AARP, citing its own data as well as that of the government. Since Facebook’s early days, cybercriminals have been mining Facebook’s direct-messaging capabilities to scam unsuspecting victims out of money. One of the earliest Facebook Messenger scams involved a message, purportedly from a friend, claiming they were stuck in a foreign country and in desperate need of immediate financial assistance to get out. It wasn’t really the friend, however, but rather a scammer who had hacked into the friend’s account. </p> <p>Imposter scams such as “the friend in a foreign country” have evolved and proliferated over the years. The common thread is the scammer either creates an account impersonating an actual Facebook account or hacks into an existing Facebook account. In either case, the scammer then uses the fake/hacked account to send private messages to the account holder’s friends that elicit either money or personal information. The messages vary, but all are designed to prey on our human vulnerabilities, including:</p> <ul> <li>the desire to be a “hero”</li> <li>the desire to appear “generous”</li> <li>the desire to win “free money”</li> <li>the desire to be loved and admired</li> <li>the desire to avoid shame or punishment</li> </ul> <p>If a scammer tries to message you, report them, Facebook advises, but that begs the larger question of how does one recognise a Facebook Messenger scam?</p> <p><strong>Current Messenger Facebook scams</strong></p> <p>According to Facebook and our cybersecurity experts, here are the most common Facebook Messenger scams today:</p> <p><span style="text-decoration: underline;"><em>Romance scams</em></span>. Preying on our desire to be loved and admired, romance scammers appear as attractive strangers with sad stories and a desire to love and be loved. The most effective romance scammers will friend a number of mutual friends before reaching out to any of them, in an attempt to make themselves seem less like strangers and more like people in the same social network. Many use photos they’ve stolen off the Internet and many pose as members of the military or as doctors, in an attempt to inspire trust, admiration, and even authority. What they all have in common is they can’t meet you just yet because they’re somewhere far away, and although it may take a bit of time, even as much as several weeks, they will eventually ask you to send money so that they can come to see you.</p> <p><span style="text-decoration: underline;"><em>Lottery scams</em></span>. Preying on our desire for “free money,” lottery scammers appear as friends or organisations who are thrilled to tell you you’ve won money in some lottery or contest. The common thread? It’s a contest you have no recollection of having entered and to get the prize, you’ll have to either pay a fee or “refundable” advance or provide personal information.</p> <p><span style="text-decoration: underline;"><em>Inheritance scams</em></span>. Also preying on our desire for free money, inheritance scammers claim to be lawyers or others who represent someone who has died and supposedly left you their estate or some portion of it – but first, you’ll have to fork over some money or personal information.</p> <p><span style="text-decoration: underline;"><em>Loan scams</em></span>. Another variation on the “free money” theme is the loan scam, whereby the scammer promises low-interest loans with no money down – except for a “refundable” application fee. Facebook points out that loan scammers may send messages via Messenger and also leave posts and comments on Pages and in Groups to legitimise themselves. However, legitimate lenders wouldn’t offer loans via Facebook Messenger, nor would they ask you for money to proceed with a loan application.</p> <p><span style="text-decoration: underline;"><em>Donation scams</em></span>. Facebook specifically warns users to watch out for “famous people” or people claiming to represent a charity hitting them up for a donation. Donation scams, which are easy money for a scammer because they are a direct request for payment, prey on our desire to be perceived, or to perceive ourselves, as generous.</p> <p><span style="text-decoration: underline;"><em>“Hey, is this you?” scams</em></span>. Consumer Affairs warns of this “phishing scam” that uses the threat of shame to goad you into giving up personal information. The scammer hacks into one of your Facebook friend’s Messenger accounts and sends you a video, asking if it’s really you in the video, and implying there’s something in the video that could embarrass you. If you ever get a message like this, Consumer Affairs urges you to ignore and delete it to avoid giving away personal information or introducing a virus onto your computer.</p> <p><strong>Red flags to watch out for</strong></p> <p>Unfortunately, Facebook Messenger scams evolve rapidly (as soon as we suss them out, there are several more to replace them). So, it’s a good idea to be aware of these warning signs that we culled from our experts:</p> <p><span style="text-decoration: underline;"><em>Someone is asking you for money</em></span>. While Facebook warns specifically against strangers asking for money, Rachel Wilson, investigative coordinator for The Smith Investigation Agency, points out to Reader’s Digest that any time anyone asks you for money over Messenger, it’s immediately suspect. “If friends or family ask you to help them in an emergency, always call to speak with them personally to confirm that the message originated with them.”</p> <p><span style="text-decoration: underline;"><em>Someone is getting a little too personal</em></span>. When someone sends you a message requesting personal information, especially financial information, it should be considered suspicious, advises Sean Messier, credit industry analyst for Credit Card Insider. Messier suggests not revealing any such information until you’re certain the message-sender is who they claim to be, but it’s probably also a good idea to never reveal any such information over Messenger at all.</p> <p><span style="text-decoration: underline;"><em>Someone is offering something for free</em></span>. You know how they say there’s no such thing as a free lunch? Well, there’s no such thing as free money on Facebook, points out Robert Siciliano, security expert. This is true for any kind of “free money” Messenger message, including those involving lotteries, loans, contest winnings, inheritances, lost bank accounts, and reimbursements of money owed.</p> <p><span style="text-decoration: underline;"><em>Someone who wants to take the conversation off Facebook (to text or email, etc)</em></span>. Facebook warns against taking conversations off Facebook unless you’re absolutely certain, beyond a shadow of a doubt, the message sender is who they say they are.</p> <p><span style="text-decoration: underline;"><em>Messages that seem out of character for the sender</em></span>. If a message seems “out of the norm” for the sender, trust your instincts and ignore it. This is doubly true if the message includes an attachment. Be very wary of opening attachments in general, and particularly if something seems “off” about the message or the sender.</p> <p><span style="text-decoration: underline;"><em>Messages rife with spelling and grammatical errors</em></span>. Facebook points out that when a message is filled with typos and grammatical errors, you should have your guard up. A single typo is one thing, but things like the misspelling of names and places are a big red flag.</p> <p><span style="text-decoration: underline;"><em>Messages from new accounts with few friends</em></span>. Roger Thompson, CEO of Thompson Cybersecurity Labs, points out that new accounts with few friends should always be considered suspicious until confirmed otherwise. Friend requests from such accounts and from duplicate friend accounts should be considered suspect as well.</p> <p>To avoid getting hacked (and used by a cybercriminal in an imposter scam), Wilson recommends updating your social media passwords regularly and always use two-factor authentication. She also notes that with Facebook use increasing among seniors, it would be a good deed to speak to older family members about Messenger scams and how to avoid them.</p> <p><em>Image credits: Getty Images </em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/true-stories-lifestyle/science-technology/facebook-messenger-scams-are-on-the-rise-heres-how-to-protect-yourself" target="_blank" rel="noopener">Reader's Digest</a>.</em></p>

How scammers use psychology to create some of the most convincing internet cons – and what to watch out for

<p><a href="https://theconversation.com/profiles/stacey-wood-473147"><em>Stacey Wood</em></a><em>, <a href="https://theconversation.com/institutions/scripps-college-2153">Scripps College</a> and <a href="https://theconversation.com/profiles/yaniv-hanoch-1341108">Yaniv Hanoch</a>, <a href="https://theconversation.com/institutions/university-of-southampton-1093">University of Southampton</a></em></p> <p><a href="https://www.experian.co.uk/blogs/latest-thinking/fraud-prevention/cybercrime-fraud-most-common-crime-uk/">Online fraud is today’s most common crime</a>. Victims are often told they are foolish for falling for it, but fraudsters use psychological mechanisms to infiltrate the defences of their targets, regardless of how intelligent they are.</p> <p>So it’s important to keep up with the latest scams and understand how they work.</p> <p>Recently, consumer protection magazine Which? <a href="https://www.which.co.uk/news/article/the-4-most-convincing-scams-weve-seen-in-2023-so-far-a7bRP9s0KJvG">identified some of the most convincing scams of 2023</a>. These scams all have one thing in common – they insidiously take advantage of people’s cognitive biases and psychological blind spots.</p> <p>They included “pig butchering” a way of fattening up victims with affection, the missing person scam which involves posting fake content on social media pages, the traditional PayPal scam, and a new scam called the “fake app alert” in which malware is hidden on apps that look legitimate.</p> <h2>Pig butchering</h2> <p>In our work as fraud psychology researchers we have noticed a trend towards hybrid scams, which combine different types of fraud. Hybrid scams often involve crypto investments and <a href="https://www.psychologytoday.com/us/blog/the-fraud-crisis/202210/new-scams-committed-forced-trafficked-labor">sometimes use trafficked labour</a> In the US alone, <a href="https://www.fbi.gov/contact-us/field-offices/springfield/news/internet-crime-complaint-center-releases-2022-statistics">the FBI recently reported</a> that people lost US $3.3 billion (£2.6 billion) in 2023 to investment fraud.</p> <p>Pig butchering is a long-term deception. <a href="https://www.cnbc.com/2023/05/02/pig-butchering-scammers-make-billions-convincing-victims-of-love.html">This type of scam</a> combines elements of <a href="https://www.actionfraud.police.uk/a-z-of-fraud/romance-scams">romance scams</a> with an investment con. The name comes from the strategy of <a href="https://www.theguardian.com/money/2023/may/22/dating-cons-and-dodgy-apps-among-most-common-scams-says-uk-watchdog">“fattening up” a victim with affection before slaughter</a>.</p> <p>It will usually begin with <a href="https://www.which.co.uk/policy-and-insight/article/pig-butchering-among-most-convincing-scams-of-2023-so-far-which-warns-aDRtr4I1UT1R">standard scam approach like a text</a>, social media message, or an introduction at a job board site.</p> <p>Victims may have their guard up at first. However, these scams can unfold over months, with the scammer slowly gaining the victims’ trust and initiating a romantic relationship all the while learning about their vulnerabilities.</p> <p>For example, details of their financial situation, job stresses, and dreams about the life they want. Romance scammers often saturate their targets with affection and almost constant contact. Pig butchering sometimes involves several trafficked people working as a team to create a single persona.</p> <p>Once the victim depends on the scammer for their emotional connection, the scammer introduces the idea of making an investment and uses fake crypto platforms to demonstrate returns. The scammers may use legitimate sounding cryptocoins and platforms. Victims can invest and “see” strong returns online. In reality, their money is going directly to the scammer.</p> <p>Once a victim transfers a substantial amount of money to the con artist, they are less likely to pull out. This phenomenon is known as the <a href="https://www.sciencedirect.com/science/article/abs/pii/0749597885900494">“sunk cost fallacy”</a>. Research has shown people are likely to carry on investing money, time and effort in activities they have already invested in and ignore signs the endeavour isn’t in their best interests.</p> <p>When the victim runs out of money or tries to withdraw funds, they are blocked.</p> <p>The victim is left with not only financial devastation, but also the loss of what they may imagine to be their most intimate partnership. They are often <a href="https://cloud-platform-e218f50a4812967ba1215eaecede923f.s3.amazonaws.com/uploads/sites/6/2021/12/VC-Who-Suffers-Fraud-Report-1.pdf">too embarrassed to discuss the experience</a> with friends and family or to report to the police.</p> <h2>PayPal scams</h2> <p>Fake payment requests are a common attack that works by volume rather than playing the long game. Payment requests appear to come from a genuine PayPal address. Fraudulent messages typically begin with a generic greeting, an urgent request and a fake link.</p> <p>For example, Dear User: You’ve received a payment, or you have paid too much. Please click link below for details. Users are directed to a spoofed website with a legitimate sounding name such as www.paypal.com/SpecialOffers and asked to enter their account information and password.</p> <p>Both of us have received these scam requests – and even we found them difficult to discern from legitimate PayPal request emails. These scams work through mimicry and play on the human tendency to trust authority. Legitimate PayPal correspondence is usually automatic bot language, so it is not difficult to imitate.</p> <p>But remember, genuine messages from PayPal <a href="https://www.paypal.com/ca/for-you/account/security/fraud-dangers#:%7E:text=Any%20email%20from%20PayPal%20will,bank%20account%2C%20or%20credit%20card.">will use your first and last name</a>.</p> <h2>The missing person scam</h2> <p>This seems to be a new scam that exploits a person’s kindness. In the past, charity scams involved posing as charitable organisation responding to a <a href="https://www.aarp.org/money/scams-fraud/info-2019/charity.html">recent, real calamity</a>.</p> <p>The new missing person scam is more sophisticated. The initial plea is a <a href="https://www.thesun.co.uk/tech/20875699/facebook-fake-missing-child-scam-warning/">fake missing person post</a> that generates likes and shares, increasing its credibility and exposure. Then the fraudster edits the content to create an investment scheme which now has the veneer of legitimacy.</p> <p>This scam may work because the initial consumers are unaware that the content is fraudulent, and there is no obvious request. In psychology, this type of persuasion is known as “<a href="https://thedecisionlab.com/reference-guide/psychology/social-proof">social proof</a>” – the tendency of individuals to follow and copy behaviour of others.</p> <h2>Fake app alerts</h2> <p>People post mobile apps, designed to steal users’ personal information, on the Google Play or Apple app store.</p> <p>The app often has a <a href="https://www.edinburghnews.scotsman.com/news/crime/another-person-comes-forward-after-banking-app-scam-3584340">legitimate function</a>, which gives it a cover. Consumers unknowingly jeopardise their private information by downloading these apps which use malware to access additional information.</p> <p>Although there has been <a href="https://tech.co/news/fake-android-apps-delete">media coverage of Android security issues</a>, many users assume malware <a href="https://www.ben-evans.com/benedictevans/2020/8/18/app-stores">cannot bypass app store screening</a>. Again, this scam plays on people’s <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2F0021-9010.92.3.639">trust in authority figures</a> to keep tjem safe.</p> <p>Discuss any investment opportunities with friends, family members or professionals. It’s much easier said than done, but exercising caution one of the best strategies to reduce the chance of becoming a fraud victim.</p> <p>Scammers count on people paying little to no attention to their emails or messages before clicking on them or providing valuable information. When it comes to scams, the devil is in the missing details.<!-- Below is The Conversation's page counter tag.

Missing Titanic sub: what are submersibles, how do they communicate, and what may have gone wrong?

<p><a href="https://theconversation.com/profiles/stefan-b-williams-1448728">Stefan B. Williams</a>, <em><a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>An extensive <a href="https://www.bbc.com/news/world-us-canada-65953872">search and rescue operation</a> is underway to locate a commercial submersible that went missing during a dive to the Titanic shipwreck.</p> <p>According to the US Coast Guard, contact with the submersible was lost about one hour and 45 minutes into the dive, with five people onboard. The vessel was <a href="https://www.9news.com.au/world/titanic-submersible-search-oceangate-expeditions-vessel-missing-as-us-coast-guard-launches-search/9d7352d8-6a6d-4dc1-afac-ce07dc63cea3">reported overdue</a> at 9.13pm local time on Sunday (12.13pm AEST, Monday).</p> <p>The expedition was being run by US company OceanGate as part of an eight-day trip with guests paying US$250,000 per head to visit the wreck site. As of <a href="https://edition.cnn.com/americas/live-news/titanic-submersible-missing-search-06-19-23/h_c2b5400daf8538d8717f50c619d762ac">Monday afternoon</a> (Tuesday morning in Australia), US Coast Guard Rear Admiral John Mauger said the watercraft likely had somewhere between 70 and the full 96 hours of oxygen available to the passengers.</p> <p>The Titanic’s wreck sits some 3,800 metres deep in the Atlantic, about 700km south of St John’s, Newfoundland. Finding an underwater vehicle the size of a small bus in this vast and remote expanse of ocean will be no small feat. Here’s what the search and rescue teams are up against.</p> <h2>OceanGate’s Titan submersible goes missing</h2> <p>Submersibles are manned watercraft that move in a similar fashion to submarines, but within a much more limited range. They’re often used for research and exploration purposes, including to search for shipwrecks and to document underwater environments. Unlike submarines, they usually have a viewport to allow passengers look outside, and outside cameras that provide a broader view around the submersible.</p> <p>The missing submersible in question is an OceanGate <a href="https://oceangate.com/our-subs/titan-submersible.html">Titan</a> watercraft, which can take five people to depths of up to 4,000m. The Titan is about 22 feet (6.7m) in length, with speeds of about 3 knots (or 5.5km per hour). Although submersibles are often connected to a surface vessel by a tether, video and photos suggest the Titan was likely operating independently of the surface ship.</p> <p>According to OceanGate’s website, the Titan is used “for site survey and inspection, research and data collection, film and media production, and deep-sea testing of hardware and software”.</p> <p>It also has a “real-time hull health monitoring (RTM) system”. This would likely include strain gauges to monitor the health of the Titan’s carbon fibre hull. A strain gauge is a kind of sensor that can measure applied force and small deformations in material resulting from changes in pressure, tension and weight.</p> <p>The Titan’s carbon fibre hull connects two domes made of composite titanium – a material that can withstand deep-sea pressures. At 3,800m below sea level (the depth of the Titanic) you can expect pressures about 380 times greater than the atmospheric pressure we’re used to on the surface of the earth.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/532840/original/file-20230620-23-c6k9lo.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/532840/original/file-20230620-23-c6k9lo.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/532840/original/file-20230620-23-c6k9lo.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=413&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/532840/original/file-20230620-23-c6k9lo.jpeg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=413&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/532840/original/file-20230620-23-c6k9lo.jpeg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=413&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/532840/original/file-20230620-23-c6k9lo.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=518&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/532840/original/file-20230620-23-c6k9lo.jpeg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=518&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/532840/original/file-20230620-23-c6k9lo.jpeg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=518&amp;fit=crop&amp;dpr=3 2262w" alt="Several tube like shapes on a rectangular concrete platform underwater" /></a><figcaption><span class="caption">Titan on the launch platform underwater, awaiting a signal to commence the dive.</span> <span class="attribution"><a class="source" href="https://oceangate.com/gallery/gallery-titan.html#nanogallery/titangallery/0/4">OceanGate</a></span></figcaption></figure> <h2>Communication and rescue efforts</h2> <p>The Titan would have had an acoustic link with its surface vessel, set up through a transponder (a device for receiving a sonar signal) on its end, and a transceiver (a device that can both transmit and receive communications) on the surface vessel.</p> <p>This link allows for underwater acoustic positioning, as well as for short text messages to be sent back and forth to the surface vessel – but the amount of data that can be shared is limited and usually includes basic telemetry and status information.</p> <p>The Titan is a battery-operated watercraft. Given it has lost all contact with its surface vessel, it may have suffered a power failure. Ideally, there would be an emergency backup power source (such as an independent battery) to maintain emergency and life support equipment – but it’s unclear if the missing vessel had any power backup on hand.</p> <p>According to reports, at least two aircraft, a submarine and sonar buoys were being used to search for the vessel. The sonar buoys will be listening for underwater noise, including any emergency distress beacons that may have gone off.</p> <p>One of the major challenges in the rescue effort will be contending with weather conditions, which will further shrink an already narrow search window.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/532842/original/file-20230620-49349-cnzdk6.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/532842/original/file-20230620-49349-cnzdk6.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/532842/original/file-20230620-49349-cnzdk6.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=413&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/532842/original/file-20230620-49349-cnzdk6.jpeg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=413&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/532842/original/file-20230620-49349-cnzdk6.jpeg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=413&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/532842/original/file-20230620-49349-cnzdk6.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=518&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/532842/original/file-20230620-49349-cnzdk6.jpeg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=518&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/532842/original/file-20230620-49349-cnzdk6.jpeg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=518&amp;fit=crop&amp;dpr=3 2262w" alt="A dark blue image with a tube like shape floating in the lower third" /></a><figcaption><span class="caption">Titan commencing a dive to 4,000m underwater.</span> <span class="attribution"><a class="source" href="https://oceangate.com/gallery/gallery-titan.html#nanogallery/titangallery/0/1">OceanGate</a></span></figcaption></figure> <h2>What might have happened?</h2> <p>In a best case scenario, the Titan may have lost power and will have an inbuilt safety system that will help it return to the surface. For instance, it may be equipped with additional weights that can be dropped to instantly increase its buoyancy and bring it back to the surface.</p> <p>Alternatively, the vessel may have lost power and ended up at the bottom of the ocean. This would be a more problematic outcome.</p> <p>The worst case scenario is that it has suffered a catastrophic failure to its pressure housing. Although the Titan’s composite hull is built to withstand intense deep-sea pressures, any defect in its shape or build could compromise its integrity – in which case there’s a risk of implosion.</p> <p>Another possibility is that there may have been a fire onboard, such as from an electrical short circuit. This could compromise the vehicle’s electronic systems which are used for navigation and control of the vessel. Fires are a disastrous event in enclosed underwater environments, and can potentially incapacitate the crew and passengers.</p> <p>Time is of the essence. The search and rescue teams will need to find the vessel before its <a href="https://web.archive.org/web/20230331121053/https://oceangateexpeditions.com/tour/titanic-expedition/">limited supplies</a> of oxygen and water run out.</p> <p>There’s an ongoing debate in scientific circles regarding the relative merit of manned submersibles, wherein each deployment incurs a safety risk – and the safety of the crew and passengers is paramount.</p> <p>Currently, most underwater research and offshore industrial work is conducted using unmanned and robotic vehicles. A loss to one of these vehicles might compromise the work being done, but at least lives aren’t at stake. In light of these events, there will likely be intense discussion about the risks associated with using these systems to support deep-sea tourism.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/208100/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/stefan-b-williams-1448728">Stefan B.

It’s an easy win-win to fundraise through Return and Earn, and it makes donating to a local charity or community group very easy.</p> <p>Return and Earn is the incredibly successful container deposit scheme in NSW, where 10 cents is refunded for every eligible drink container returned for recycling through the network of 600+ return points across the state.</p> <p>Since launching over five years ago, <a href="https://returnandearn.org.au" target="_blank" rel="noopener">Return and Earn</a> has become an important and well used channel for charities and community groups fundraising to support a range of local and broader causes. Groups such as Rotary and Lions Clubs, animal rescue organisations, and fire and rescue services are just a few of the many different cohorts that have partnered with Return and Earn and relied on the generosity of NSW citizens to help them do vital work in their communities.</p> <p>“We’ve seen many groups really embrace the scheme, showing a humbling passion for giving back to the community – whether it’s to help fund an event for a local club, or to donate to a charity,” said Danielle Smalley, CEO of scheme coordinator, Exchange for Change.</p> <p>“Some of these groups have raised a lot of money from recycling drink containers through Return and Earn. Often local residents and businesses are handing over their containers or donating their refunds to support the cause, proving there is enormous goodwill in the community.”</p> <p>The Gerringong Lions Club recently celebrated one million containers collected, raising $100,000 that was donated to a variety of causes including medical research, local sporting facilities, as well as helping both Australian and oversees Lions Clubs provide relief during catastrophes.</p> <p><img class="alignnone size-full wp-image-67811" src="https://www.readersdigest.com.au/wp-content/uploads/2023/06/Gerringong-Lions-Club-image-2-for-article-2_RD.jpg" alt="" width="770" height="500" /></p> <p><em>The Gerringong Lions Club are now raising around $20,000 each year.</em></p> <p>The COVID shutdowns and restrictions put a halt to the activities that would normally bring funds to the club. Return and Earn was the only means for the club to generate an income to help the community during this time.</p> <p>As routine users of the scheme, the Gerringong Lions Club are now raising around $20,000 each year, all the while making positive impacts to the environment.</p> <p>Bruce Ray is a past president and active member of the club, and says he gets a sense of satisfaction knowing they are helping the community while also looking out for the environment.</p> <p>“We have the bins at the hotel, the bowling club, and campgrounds. The club also provides the container collection bins for events such as weddings and uses them at local New Years’ Eve events,” said Mr Ray.</p> <p>In Cobar, the local Rotary Club is also using Return and Earn to support the work in their community. They partnered with the local Girl Guides who help the club sort through any drink containers collected. They’ve now raised more than $25,000 since they began in early 2020.</p> <p>Club Secretary Gordon Hill said that one of the benefits for the Girl Guides is the real-world experience in seeing how much locally created waste can be recycled.</p> <p>“It also provides a healthy opportunity for a challenge to see which girls can pack the most containers during a 1.5 to 2 hour session. The record currently stands at 3,080, but the challenge continues,” Gordon added.</p> <p><img class="alignnone size-full wp-image-67813" src="https://www.readersdigest.com.au/wp-content/uploads/2023/06/Cobar-Rotary-Club-image-for-article-2_RD.jpg" alt="" width="770" height="500" /></p> <p><em>In Cobar, the local Rotary Club has partnered with the Girl Guides to help with sorting!</em></p> <p>Since Return and Earn launched in December 2017, over $42 million has been raised through donations and return point hosting fees. The funds have made a significant difference to individuals and groups who have received the support.</p> <p>“There are a lot more collection drives in the community that we don’t track, so the total fundraising amount is in fact even higher,” Ms Smalley said.</p> <p>“We encourage all our Return and Earn users to consider donating containers to a local charity or community group either at the nearest Return and Earn machine or using the Return and Earn app.</p> <p>“And if you’re a member of a group looking for an easy and effective way to fundraise, consider Return and Earn where you can double the benefit by raising funds while also helping the environment.”</p> <p>Every Return and Earn machine features a local donation partner, to whom users can donate part or all of their refunds to. The charity listed changes every six months to give as many groups as possible the opportunity.</p> <p>Charities and groups can also elect to be listed on the Return and Earn app, allowing anyone using the app at a machine or automated depot to donate direct to their favourite charity. There are currently over 170 charities featured on the app.</p> <p>When using a Return and Earn machine, select donate, then select which of the charities listed you want the funds to go. If you’re using the Return and Earn app, simply select donation as your payout option and then select the charity or group you would like to donate your refund to.</p> <p>“Contributions don’t need to be big to make a difference. It can be as easy as collecting a few eligible drink containers and donating them to a charity, helping local communities thrive while looking after the environment.” said Ms Smalley.</p> <p>For more information on donating through Return and Earn visit <a href="https://returnandearn.org.au/donate/" target="_blank" rel="noopener">returnandearn.org.au/donate/</a></p> <p><em>Images: Supplied</em></p> <p><em>This is a sponsored article produced in partnership with Return and Earn.</em></p>

An El Niño looms over Australia’s stressed electricity system – and we must plan for the worst

<p><a href="https://theconversation.com/profiles/dylan-mcconnell-1602">Dylan McConnell</a>, <em><a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em> and <a href="https://theconversation.com/profiles/iain-macgill-576">Iain MacGill</a>, <em><a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>The Bureau of Meteorology this week declared a 70% chance of an <a href="https://media.bom.gov.au/releases/1170/the-bureau-of-meteorology-issues-an-el-nino-alert/">El Niño</a> developing this year. It’s bad timing for the electricity sector, and means Australians may face supply disruptions and volatile prices.</p> <p><a href="http://www.bom.gov.au/climate/updates/articles/a008-el-nino-and-australia.shtml">El Niño events</a> are <a href="https://theconversation.com/from-floods-to-fire-a-climate-scientist-on-the-chances-el-nino-will-hit-australia-this-year-197408">associated with</a> increased temperatures and heatwaves. These conditions drive demand for electricity, especially in summer.</p> <p>These same conditions can also mean some generators don’t produce at full capacity. And unfortunately, the likely El Niño comes as the electricity sector grapples with other significant headwinds.</p> <p>Australia’s electricity grid may be fine this summer. But given what’s on the horizon, it would be prudent to plan for the worst.</p> <h2>How does hot weather affect energy supplies?</h2> <p>Increased air conditioning use in summer can cause <a href="https://aemo.com.au/-/media/files/electricity/nem/planning_and_forecasting/nem_esoo/2022/forecasting-approach-electricity-demand-forecasting-methodology.pdf">demand to peak</a>, particularly during heatwaves, as the below graph shows.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=208&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=208&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=208&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=262&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=262&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=262&amp;fit=crop&amp;dpr=3 2262w" alt="Scatterplot of New South Wales demand and temperature, example based on 2017 calendar year" /><figcaption><span class="caption">Scatterplot of New South Wales demand and temperature, example based on 2017 calendar year.</span> <span class="attribution"><span class="source">AEMO</span></span></figcaption></figure> <p>At the same time, electricity generators – including coal, gas, <a href="https://www.climatechangeinaustralia.gov.au/en/projects/esci/esci-case-studies/case-study-heat/">solar and wind</a> – can become less efficient in hot temperatures, and so provide less energy to the system. And the hotter transmission lines get, the less electrical current they can safely carry. This lowers their capacity to transport energy.</p> <p>When the electricity grid is under stress, this can lead to “load shedding” or blackouts – when power companies deliberately switch off the power supply to groups of customers to prevent the overall system from becoming dangerously unstable.</p> <p>This happened in Victoria in early 2019, when more than <a href="https://www.abc.net.au/news/2019-01-26/victorian-blackouts-what-caused-them-and-is-this-the-new-normal/10751412">200,000 customers</a> lost power during a period of extreme heat.</p> <p>El Niño events are also associated with reduced rainfall. Among other effects on the electricity grid, this can reduce output from hydroelectricity generators (which produce electricity by pumping water through turbines). This <a href="https://theconversation.com/praying-for-rain-50085">occurred</a> in Tasmania in 2016, and contributed to an energy crisis in that state.</p> <h2>Other headwinds are blowing</h2> <p>Aside from facing a likely El Niño, the electricity sector faces other headaches.</p> <p>Earlier this year, the Australian Energy Market Operator <a href="https://aemo.com.au/newsroom/media-release/aemo-issues-nem-reliability-update">warned</a> electricity demand “may exceed supply” at times over the next decade due to factors such as weather conditions or generator outages.</p> <p>The market operator pointed to delays to the Snowy 2.0 hydro project and the gas-fired <a href="https://www.afr.com/companies/energy/new-snowy-ceo-can-t-rule-out-further-delays-at-projects-20230213-p5cjzr">Kurri Kurri Power Station</a>, both in New South Wales.</p> <p>The Kurri Kurri project has been delayed for a year. It was scheduled to begin operating in December this year – in time for the first summer since the Liddell coal-fired power station closed.</p> <p>The Australian Energy Market Operator said the electricity system was expected to meet the “reliability standard” in all regions for the next five years. The <a href="https://www.aemc.gov.au/energy-system/electricity/electricity-system/reliability#:%7E:text=What%20is%20the%20Reliability%20Standard,to%20be%20met%20each%20year.">standard requires</a> at least 99.998% of forecast demand be met each year. Unmet demand can lead to interrupted supply, or blackouts.</p> <p>But the operator also said delays to the Kurri Kurri project posed risks to reliability in NSW this summer.</p> <p>Adding to the pressures on the system, Queensland’s Callide C coal-fired power station is still not back to capacity more than two years after an explosion at the site. The station’s owners last week <a href="https://www.afr.com/companies/energy/energy-grid-fears-as-callide-c-return-delayed-until-mid-2024-20230529-p5dc90">announced</a> the plant would not be fully operational until mid-2024.</p> <p>Combine all this with a likely El Niño, and the electricity sector may be facing a challenging summer.</p> <h2>El Niño years are not normal</h2> <p>In August, the Australian Energy Market Operator is due to publish a new <a href="https://aemo.com.au/-/media/files/electricity/nem/planning_and_forecasting/nem_esoo/2022/esoo-and-reliability-forecast-methodology-document-2022.pdf">assessment</a> of the grid’s expected reliability over the next decade. It may well show reliability standards will be achieved.</p> <p>On first blush, that sounds like good news. However, the way the assessment is derived may mask the real risk during El Niño periods.</p> <p>The assessment combines a number of scenarios, which are based on different <a href="https://aemo.com.au/en/energy-systems/electricity/national-electricity-market-nem/nem-forecasting-and-planning/forecasting-and-reliability/projected-assessment-of-system-adequacy">forecasts</a> of electricity demand. The scenarios based on average weather conditions are given the most weight.</p> <p>But if an El Niño arrives, this summer will not be average. We’re likely to experience very hot and dry conditions. This may lead to higher demands on the energy system, and a greater likelihood of blackouts.</p> <p>This won’t be properly reflected in the assessment. So the grid may be deemed reliable even though electricity supplies are under immense pressure.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=3 2262w" alt="repair person climbs power pole" /><figcaption><span class="caption">The grid may be deemed reliable even though it’s under pressure.</span> <span class="attribution"><span class="source">Shutterstock</span></span></figcaption></figure> <h2>What can be done?</h2> <p>You might find all this news worrying. But there are measures and technologies in place to help reduce the risks.</p> <p><a href="https://aemo.com.au/en/energy-systems/electricity/emergency-management/reliability-and-emergency-reserve-trader-rert">A mechanism</a> exists that allows the market operator to secure emergency energy reserves. It could mean, for example, calling on a large industrial plant to pause operations to reduce its electricity use, or starting up a standby diesel generator. The operator can start procuring this months ahead of time, and will no doubt be monitoring the situation closely.</p> <p>In the medium term, the uptake of so-called “consumer energy resources” such as rooftop solar farms and small-scale battery storage shows promise. These technologies are located at homes and businesses. They can reduce demand on the grid at peak times and can potentially be built faster than big projects.</p> <p>Longer term, we need to build more “stuff”. This includes renewable energy and other “dispatchable” resources – which can provide energy when it’s needed – as well as more transmission infrastructure.</p> <p>Several federal funding measures – the <a href="https://www.energy.gov.au/government-priorities/energy-supply/capacity-investment-scheme">Capacity Investment Scheme</a> and <a href="https://www.energy.gov.au/news-media/news/rewiring-nation-supports-its-first-two-transmission-projects">Rewiring the Nation</a> – might help realise these projects.</p> <p>The reality is that ageing coal plants are closing – and while they remain open, they’re contributing to reliability challenges in the energy system. Unchecked climate change will also add considerable strain, through natural disasters and more extreme weather.</p> <p>Unfortunately, investment in renewable and other low-emission technology has been <a href="https://www.cleanenergycouncil.org.au/news/clean-energy-construction-peaks-as-investment-pipeline-battles-headwinds">slower than necessary</a>. This has slowed Australia’s emissions reduction efforts and cast questions over the reliability of our energy supplies as an El Niño looms.<!-- Below is The Conversation's page counter tag.

For instance, many contained images of autumn leaves, another popular ecological event to view in Japan.</p> <p>The locations and timestamps of the remaining cherry blossom images were then used to generate marks on a map of Japan showing the seasonal wave of sakura blossoms, and to estimate peak bloom times each year in different cities.</p> <h2>Checking the data</h2> <p>An important component of any scientific investigation is validation – how well does a proposed solution or data set represent the real-world phenomenon under study?</p> <figure class="align-right zoomable"><a href="https://images.theconversation.com/files/528702/original/file-20230528-21-4fxpkv.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/528702/original/file-20230528-21-4fxpkv.png?ixlib=rb-1.1.0&q=45&auto=format&w=237&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/528702/original/file-20230528-21-4fxpkv.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=591&fit=crop&dpr=1 600w, https://images.theconversation.com/files/528702/original/file-20230528-21-4fxpkv.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=591&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/528702/original/file-20230528-21-4fxpkv.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=591&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/528702/original/file-20230528-21-4fxpkv.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=743&fit=crop&dpr=1 754w, https://images.theconversation.com/files/528702/original/file-20230528-21-4fxpkv.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=743&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/528702/original/file-20230528-21-4fxpkv.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=743&fit=crop&dpr=3 2262w" alt="" /></a><figcaption><span class="caption">Blossom dates calculated from social media images compare well with official data.</span> <span class="attribution"><span class="source">ElQadi et al.</span>, <span class="license">Author provided</span></span></figcaption></figure> <p>Our study using social network site images was validated against the detailed information published by the <a href="https://www.japan.travel/en/see-and-do/cherry-blossom-forecast-2023/">Japan National Tourism Organization</a>.</p> <p>We also manually examined a subset of images to confirm the presence of cherry flowers.</p> <p>Plum flowers (<em>Prunus mume</em>) look very similar to cherry blossoms, especially to tourists, and they are frequently mistaken and mislabelled as cherry blossoms.
