‘Girl math’ may not be smart financial advice, but it could help women feel more empowered with money

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/ylva-baeckstrom-1463175">Ylva Baeckstrom</a>, <a href="https://theconversation.com/institutions/kings-college-london-1196">King's College London</a> If you’ve ever calculated cost per wear to justify the price of an expensive dress, or felt like you’ve made a profit after returning an ill-fitting pair of jeans, you might be an expert in <a href="https://www.standard.co.uk/news/world/girl-maths-tiktok-trend-its-basically-free-b1100504.html">“girl math”</a>. With videos about the topic going viral on social media, girl math might seem like a silly (<a href="https://www.glamourmagazine.co.uk/article/girl-math-womens-spending-taken-seriously">or even sexist</a>) trend, but it actually tells us a lot about the relationship between gender, money and emotions. Girl math introduces a spend classification system: purchases below a certain value, or made in cash, don’t “count”. Psychologically, this makes low-value spending feel safe and emphasises the importance of the long-term value derived from more expensive items. For example, girl math tells us that buying an expensive dress is only “worth it” if you can wear it to multiple events. This approach has similarities to <a href="https://www.investopedia.com/terms/m/modernportfoliotheory.asp">portfolio theory</a> – a method of choosing investments to maximise expected returns and minimise risk. By evaluating how each purchase contributes to the shopping portfolio, girl math shoppers essentially become shopping portfolio managers. <h2>Money and emotions</h2> People of all genders, rich or poor, feel anxious when dealing with their personal finances. Many people in the UK do not understand pensions or saving enough to <a href="https://www.ons.gov.uk/employmentandlabourmarket/peopleinwork/workplacepensions/articles/pensionparticipationatrecordhighbutcontributionsclusteratminimumlevels/2018-05-04">afford their retirement</a>. Without motivation to learn, people avoid dealing with money altogether. One way to find this motivation, as girl math shows, is by having an emotional and tangible connection to our finances. On the surface, it may seem that women are being ridiculed and encouraged to overspend by using girl math. From a different perspective, it hints at something critical: for a person to really care about something as seemingly abstract as personal finance, they need to feel that they can relate to it. Thinking about money in terms of the value of purchases can help create an <a href="https://www.thetimes.co.uk/article/every-time-i-use-my-card-my-phone-buzzes-and-that-stops-me-shopping-ps0fjx6nj">emotional relationship</a> to finance, making it something people want to look after. <figure><iframe src="https://www.youtube.com/embed/GPzA7B6dcxc?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>The girl math we need</h2> Women are a consumer force to be reckoned with, controlling <a href="https://www.forbes.com/sites/bridgetbrennan/2015/01/21/top-10-things-everyone-should-know-about-women-consumers/#7679f9d6a8b4">up to 80%</a> of consumer spending globally. The girl math trend is a demonstration of women’s mastery at applying portfolio theory to their shopping, making them investment powerhouses whose potential is overlooked by the financial services industry. <a href="https://www.theguardian.com/world/2019/oct/28/women-paid-less-than-men-over-careers-gender-pay-gap-report">Women are disadvantaged</a> when it comes to money and finance. Women in the UK earn on average £260,000 less than men during their careers and the retirement income of men is twice as high as women’s. As I’ve found in <a href="https://www.routledge.com/Gender-and-Finance-Addressing-Inequality-in-the-Financial-Services-Industry/Baeckstrom/p/book/9781032055572">my research</a> on gender and finance, women have lower financial self-efficacy (belief in their own abilities) compared to men. This is not helped by women feeling patronised when seeking financial advice. Because the world of finance was created by men for men, its language and culture are <a href="https://www.routledge.com/Gender-and-Finance-Addressing-Inequality-in-the-Financial-Services-Industry/Baeckstrom/p/book/9781032055572">intrinsically male</a>. Only in the mid-1970s did women in the UK gain the legal right to open a bank account without a male signature and it was not until 1980 that they could apply for credit independently. With the law now more (<a href="https://www.worldbank.org/en/news/press-release/2023/03/02/pace-of-reform-toward-equal-rights-for-women-falls-to-20-year-low">but not fully</a>) gender equal, the financial services industry has failed to connect with women. Studies show that 49% of women are <a href="https://www.ellevest.com/magazine/disrupt-money/ellevest-financial-wellness-survey">anxious about their finances</a>. However they have not bought into patronising offers and <a href="https://www.fa-mag.com/news/gender-roles-block-female-financial-experience--ubs-says-73531.html">mansplaining by financial advisers</a>. This outdated approach suggests that it is women, rather than the malfunctioning financial system, <a href="https://www.theguardian.com/commentisfree/2020/sep/16/women-are-not-financially-illiterate-they-need-more-than-condescending-advice">who need fixing</a>. Women continue to feel that they do not belong to or are able to trust the world of finance. And why would women trust an industry with a <a href="https://www.ons.gov.uk/employmentandlabourmarket/peopleinwork/earningsandworkinghours/bulletins/genderpaygapintheuk/2019">gender pay gap</a> of up to 59% and a severe lack of women in senior positions? Girl math on its own isn’t necessarily good financial advice, but if it helps even a handful of women feel more empowered to manage and understand their finances, it should not be dismissed.  <a href="https://theconversation.com/profiles/ylva-baeckstrom-1463175">Ylva Baeckstrom</a>, Senior Lecturer in Finance, <a href="https://theconversation.com/institutions/kings-college-london-1196">King's College London</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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

Over a million Aussies may be unable to contact triple-0 as two major telcos cut their 3G networks. Telstra's network will be closed on June 30 this year followed by Optus, which will shut their 3G network in September. While most late model phones are now serviced by either 4G or 5G networks, there are many devices that still rely on 3G. Approximately 113,000 Telstra customers have not upgraded their 3G handsets, while Optus have not disclosed a figure. 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. In March, Communications Minister Michelle Rowland was informed that 740,000 Australians were in that category. A month later, that figure was revised to over a million. "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. “I am considering the detail provided and next steps, and the government will have more to say about the 3G switchover soon.” She also said that they were open to delaying the switchover "if warranted in the public interest”. “Options exist under law for the government to consider proposals to delay the planned switchover, subject to consultation and procedural processes,” she said. Telstra has informed customers about what to do if they are affected, and how they could check. “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. “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." “Without taking the recommended action you won’t be able to connect to a network after 30 June 2024,” they warned. 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. Optus have also encouraged customers to contact them if they think they may be affected. Image: Getty

Detection dogs to lead search for Samantha Murphy's body

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. 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. “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 ABC Radio. “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. “We still haven’t recovered her phone and her watch. We’ll use all those specialist skills.” He also added that the "intelligence" they received, which sparked this fresh search did not come from interviews with accused murderer, Patrick Orren Stephenson. “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. In another statement, Victoria police also said that the search on Thursday is not a "full-scale targeted search". "This is not a full-scale targeted search as took place yesterday in Buninyong with a range of specialist resources," they said. "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." 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. He will next face court on August 8. Images: Nine News

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

<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> 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. 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. 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.) 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. 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. 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. <h2>Time and space</h2> 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. 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? 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. 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. 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. 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. 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. 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. <h2>The elusive Moon</h2> 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. 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. 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. 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. 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. 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. 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. 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.<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/224503/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/emily-ohara-874665">Emily O'Hara</a>, Senior Lecturer, Spatial Design + Temporary Practices, <a href="https://theconversation.com/institutions/auckland-university-of-technology-1137">Auckland University of Technology</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

8 places you should never keep your phone

In your pocket 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. 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. In your bra 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 & Fitness reports. In your bed or under your pillow 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. 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. Plugged in 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. Close to your face 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. In your glovebox 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. On your beach towel 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. Anywhere in the bathroom 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. “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.

Disabled customer "crushed" by Coles' new smart gate

A customer using a wheelchair has been crushed by Coles' new controversial smart gates, just months after it was rolled out in Aussie stores. The smart gates were added to self-serve check-outs across the country late last year as a security measure against thieves. The gates were installed with a range of other security measures in response to rising theft rates, including "CCTV, electronic article surveillance (EAS), and in some stores new smart gate technology that automatically opens as customers make payment for their products," according to a Coles spokesperson. But on Tuesday a customer, who chose to remain anonymous, said that one of the smart gates “slammed shut” on them and their wheelchair, while they were on their routine shopping trip with their son. After buying a few things the customer said that they were heading to the "wide open" gate, and their son passed through safely. But, when they tried to follow, the gate abruptly closed “hitting” their arms and “crushing” their wheelchair. The gate began to beep and only reopened when the customer pushed their way through. Fortunately, the customer was not injured but wanted to raise awareness on the issue. “I’ll be calling every day until SOMEONE tells me how to avoid being crushed next time,” they said. A few other annoyed customers slammed the "invasive" and "annoying" technology. “One literally snapped shut on our pram as we were pushing our kiddo through,” one person wrote on social media. “I’d walked out the store first, pram and husband following behind. Especially cause they make them too small for you to go side-by-side! “It’s insane, and I refuse to look at any self check out or check out with that in the path.” Another added: “Not long until an elderly person is knocked over by them and breaks their hip or similar." "It’s turning into a jail rather than a supermarket,” a third wrote. Image: Getty

These 10 smart grocery swaps can help reverse diabetes

Diagnosis diabetes It can feel daunting to be faced with the need to make a major lifestyle change. You enjoy food, and you should. At Reader’s Digest, we like to think nature designed nutrition to taste delicious so it can be a source of pleasure in your day that’s fun to look forward to. If you’ve been diagnosed with diabetes or pre-diabetes, this diagnosis doesn’t have to take over your whole identity and all the things that bring you joy. There are ways to adapt some of your favourite foods so you can still have them! Registered dietitian Jackie Newgent lists interesting meal swaps you can make so that classic dishes can be healthier, while still plenty pleasurable. With some wisdom and dedication, it can be possible to turn your condition around and feel great for good. Pair starchy with non-starchy veggies Instead of: one kilo potatoes Buy: 500g kilo potatoes plus 500g cauliflower This mashed potato hack keeps your total carbs in check without forgoing flavour. Whip equal parts boiled potatoes together with roasted or boiled cauliflower. The results of this dynamic duo may help you better manage your blood glucose, since they’re carb-friendlier than a huge bowl of mashed potatoes alone: 100 grams of cooked potatoes without skin provides 22 grams of total carbohydrates, versus 13 grams total carbohydrate in the 100 gram combination of cooked potatoes and cauliflower. Pick fruit you can chew <div> Instead of: one litre apple juice Buy: one bag of apples Enjoy whole fruit rather than just the juice whenever possible to get all the fibre of the naturally sweet fruit with its edible peel…plus chewing satisfaction. One medium apple contains 4.4 grams of fibre while a 200ml glass or juice box of 100-percent apple juice has 0.4 grams of fibre. The soluble fibre in apples can help slow down absorption of sugars. Polyphenols in apples may have powerful antioxidant properties. Grill a better burger Instead of: 500g 85% lean ground beef patties Buy: 500g ground chicken breast Gram for gram, chicken breast has significantly less saturated fat than the marbly beef of classic burgers. Specifically, an 85g cooked 85% lean ground beef patty has five grams of saturated fat compared to 0.6 grams of saturated fat for a cooked patty made from 85g of chicken breast meat. Keeping saturated fat intake low is especially important when you have diabetes to help keep your heart healthy. Pro-tip: make chicken burgers juicier and tastier by combining ground chicken breast with a little plain yogurt, rolled oats, and herbs and spices before cooking. Look for live cultures in the dairy section Instead of: one container regular cottage cheese Buy: one container plain low-fat Greek yogurt or cultured cottage cheese Probiotics are “good” bacteria that help keep your gut healthy. For people with type 2 diabetes, research published in Advances in Nutrition suggested that probiotics may also have glucose-lowering potential. So, pop products with live active cultures (probiotics) into your cart while strolling by the dairy aisle. Choose plain low-fat Greek yogurt or cultured cottage cheese. Be sure to read the nutrition labels, since probiotics aren’t in all dairy foods. And, for the lower-sodium pick, stick with yogurt. Choose healthier-sized grain portions Instead of: 1/2 dozen bakery-style plain bagels Buy: one package of wholegrain English muffins Swapping wholegrain in place of refined grain products helps kick up fibre and other plant nutrients. Studies suggests this is linked to lower risk of type 2 diabetes. Also, opting for healthier-sized varieties, such as wholegrain English muffins rather than big bakery-style plain bagels helps cut kilojoules (and carbs) – not enjoyment – while promoting a healthier weight. In fact, you’ll slash over 1000 kilojoules by enjoying a whole-wheat English muffin instead of that oversized 140g bagel. Get your munchies with benefits Instead of: one bag of potato chips Buy: one jar or bulk-bin container of roasted peanuts It’s a no-brainer: a small handful of nuts is a better bet than potato chips. Peanuts, for instance, offer a triple whammy of dietary fibre, plant protein and healthy fat, which can boost satiety. Greater satisfaction means a greater chance you’ll keep mealtime portions right-sized. When peanuts or other nuts are eaten along with carb-rich foods, they can help slow down the blood sugar response. Plus, a Mediterranean study found that higher nut consumption may be associated with better metabolic status. Dress a salad smartly Instead of: one bottle of fat-free salad dressing Buy: one small bottle olive oil plus one small bottle balsamic or red wine vinegar Some bottled salad dressings can trick you. For instance, “fat-free” salad dressing may be loaded with added sugars. (For reference: four grams of sugar is equal to one teaspoon.) So, read salad dressing labels carefully for sneaky ingredients, especially excess salt (over 250 milligrams of sodium per two-tablespoon serving) or added sugars (more than five grams added sugars per two-tablespoon serving). Better yet, keep it simple and make your own vinaigrette using 2-3 parts oil to 1 part vinegar. Select less salty soup Instead of: one can/carton of vegetable- or bean-based soup Buy: one can/carton of low-sodium vegetable- or bean-based soup When compared to people without diabetes, sodium levels were higher in patients with type 2 diabetes, based on a meta-analysis published in European Journal of Nutrition. Curbing sodium intake is beneficial for people with diabetes since too much may increase your risk for high blood pressure. So, slurp up soup that’s low in sodium. And kick up flavour with a splash of cider vinegar, grated citrus zest, herbs, spices, or a dash of hot sauce. Go for "naked" fish Instead of: Breaded fish sticks Buy: Frozen salmon fillets Cut salmon into large cubes, season, and grill on skewers. Or make fish sticks by simply cutting into skinny fillets, season and roast. Why? Research published in Diabetes Care finds that eating oily fish may be associated with a lower risk of type 2 diabetes. Non-oily fish, like the whitefish in fish sticks, didn’t show this link. Salmon is an oily fish and a major source of omega-3 fatty acids, a heart-friendly fat. Plus: when you make your own salmon skewers or sticks, you won’t have extra carbs from breading. Do dip with a punch of protein Instead of: one container of sour cream & onion dip Buy: one container of pulse-based dip, like hummus Wise snacking can be helpful for managing blood glucose. It can also be delicious. Dunk veggies or wholegrain pita wedges into pulse-based dip, like hummus, black bean dip, or lentil dip. Check this out: one-quarter cup (that’s 60 grams) of onion dip has 870 kiljoules, five grams of saturated fat, 1.2 grams of protein, and 0.1 grams of fibre, while one-quarter cup hummus has 590 kilojoules, 1.5 grams of saturated fat, 4.7 grams of protein, and 3.3 grams of fibre. Hummus clearly wins!

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

<a href="https://theconversation.com/profiles/kayleen-manwaring-8735">Kayleen Manwaring</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> 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. 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? <h2>What is spam?</h2> 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. That said, “spam” generally <a href="https://www.oecd-ilibrary.org/docserver/232784860063.pdf?expires=1693541947&id=id&accname=ocid177499&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. 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>. 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. 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>. <h2>Where do spammers get my details?</h2> Each time you enter your email address or phone number into an e-commerce website, you may be handing it to spammers. 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. 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>. 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. 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>. <h2>Is spamming against the law?</h2> 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. 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. 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. 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 & Auto</a> were fined more than A$6 million in total for breaches. 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. 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. 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. 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). <h2>Staying safe from spam (and cyberattacks)</h2> 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. 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: <ol> <li> use a spam filter and block spammers – email and telecommunications providers often supply useful tools as part of their services </li> <li> unsubscribe from any emails you no longer want to receive – even if you originally agreed to receive them </li> <li> 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 </li> <li> install cybersecurity updates for your devices and software as you get them </li> <li> 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 </li> <li> 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 </li> <li> 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>. <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/208665/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> </li> </ol> <a href="https://theconversation.com/profiles/kayleen-manwaring-8735">Kayleen Manwaring</a>, Senior Research Fellow, UNSW Allens Hub for Technology, Law & Innovation and Senior Lecturer, School of Private & Commercial Law, UNSW Law & Justice, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why you need to stop charging your phone overnight

You charge your phone all night 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. 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. You use vibrations for notifications 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. “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.” You keep apps open that you're not using 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. 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. You allow unnecessary permissions 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. You have one of these apps 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. 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. Your screen is always extremely bright 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. 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. You keep your phone out at the beach 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. You keep your phone in your bed or under your pillow Tucking your phone under your pillow when you sleep is another way to shorten its life, thanks to heat build-up. You don't keep your software up to date 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.

"I can't wake Mummy up": Olympian dies at 43

A former Olympic swimmer has passed away suddenly at the age of 43 while on a trip with her family. Helen Smart, a British swimming champion who competed at the 2000 Sydney Olympics, was found unresponsive by her four-year-old daughter Heidi when she tried to climb into bed with her parents. Heidi then woke up her father Craig Smart, saying, "Daddy, I can't wake Mummy up," before Craig discovered his wife lying next to him dead. Smart's mother confirmed the news of her passing, telling the <a href="https://www.dailymail.co.uk/news/article-12413199/Ex-Olympic-swimmer-turned-headteacher-Helen-Smart-dead-four-year-old-daughter-heartbreaking-video-shows-mother-paddleboarding-hours-sudden-death-aged-42.html" target="_blank" rel="noopener">MailOnline</a>, "Heidi had woken up in the night and tried to get into bed with her. She said to her daddy, 'Mummy won't wake up''. He said, 'Oh, she must be very tired Heidi - you go back to bed'." "He put the torch on and he said later that when he looked he could tell." Linda continued, "We're distraught. They don't know what it is but they think it must have happened shortly after she went to bed. She just died in her sleep." Just hours before her sudden passing, Helen and her family had been paddle boarding in the north of England, while on a trip for her brother Robert's 40th birthday. Helen had not been suffering with any illnesses her family knew of. Linda said, "At midnight, she went to bed telling me: 'I'll go to bed now mum as I know I'll be woken at 6am by Heidi. I just want to get some sleep in as I've had a long day.'" Linda was then woken by Robert at 4am who said, "Mum, dad, you need to keep up - we think Helen's died." Smart's father John said he and his wife "can't comprehend how she could simply go to sleep and not wake up." Helen became a school principal after her retirement from swimming and was enjoying her new life. Craig Smart took to her school's Facebook page to say his wife "loved the school, staff, children and parents so much." "She was so proud to reach her goal of being Head Teacher," he continued. "She used to say to me all the time she could never see herself at another school. She was Worsley Mesnes through and through! I remember only last week she said her goal was to get the school to outstanding and that she had the right staff to achieve this!" "I hope you all keep learning like champions. Please learn from this and live your best life, no regrets, take lots of photos, make memories and keep smiling just like Helen always did!" he added. Image credits: Twitter / Getty Images

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

<a href="https://theconversation.com/profiles/rob-nicholls-91073">Rob Nicholls</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> 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>. Most of the payments were for small amounts (less than A$5,000) and were not flagged by the ATO’s own monitoring systems. 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. 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. <h2>How these scams work</h2> 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. 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. 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>. 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. It is a sadly simple scam. <h2>How government can improve</h2> 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. 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. 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. 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. 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. Sadly, the millions of records stolen in the Optus, Medibank and Latitude Financial breaches have not led to a similar level of vigilance. 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. 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. <h2>Protecting yourself</h2> 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. It also helps to protect your Tax File Number. There are only four groups that ever need this number. 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 after you have started work. 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. 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. 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.<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/210459/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/rob-nicholls-91073">Rob Nicholls</a>, Associate professor of regulation and governance, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Jeanie Houston - The joy of getting a letter from loved ones overseas. Tina Karanastasis - Having pen pals (a fad in my younger years), writing and receiving handwritten letters, building relationships through shared moments and time spent together face to face. Deirdre Hudson - Being able to go anywhere without someone calling you Lois Parkes - Going to a library to research the answer Gini Glenn - Nothing! I love the internet and mobile phones. You can always leave your phone at home or turn it off. Lovely to have choices. Teresa Hamilton Gross - Having a conversation with someone who is not looking at their cell phone. Jan Gundersen - Being out at a restaurant & talking to each other! Don Gregor - Getting lost while driving/traveling. Met the most interesting people and had the most memorable times. Ann Hazlewood - Sitting around talking to family Ellen Clarke - Sitting around the kitchen table & everyone talking at once, miss it! Christine Armstrong - Letters! I miss getting letters from friends and family in the mail box Beverley Collison - Listening to stories of the older generation when I was younger. And telephone conversations. Did we miss anything? Let us know if there are other things that you miss from the pre-internet times!

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

<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> 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. How are we to make sense of this significant digital dimension of modern life? 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. And we can turn this question on ourselves: why am I online? <h2>What are we doing when we go online?</h2> 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. 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. 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? <h2>The ever-present need to manage our emotions</h2> 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>. 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. 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. <figure><iframe src="https://www.youtube.com/embed/PQkNb4CLjJ8?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Digital emotion regulation is becoming increasingly common in our everyday lives.</figcaption></figure> 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. <h2>Digital technologies are becoming key tools of emotion regulation</h2> 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. 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. 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. 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. Some participants in our study described how they built what we called “emotional toolkits”.

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

Facebook Messenger scams prey on our vulnerabilities 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. 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: <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> 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? Current Messenger Facebook scams According to Facebook and our cybersecurity experts, here are the most common Facebook Messenger scams today: Romance scams. 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. Lottery scams. 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. Inheritance scams. 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. Loan scams. 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. Donation scams. 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. “Hey, is this you?” scams. 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. Red flags to watch out for 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: Someone is asking you for money. 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.” Someone is getting a little too personal. 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. Someone is offering something for free. 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. Someone who wants to take the conversation off Facebook (to text or email, etc). 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. Messages that seem out of character for the sender. 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. Messages rife with spelling and grammatical errors. 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. Messages from new accounts with few friends. 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. 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.

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

<a href="https://theconversation.com/profiles/stacey-wood-473147">Stacey Wood</a>, <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> <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. So it’s important to keep up with the latest scams and understand how they work. 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. 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. <h2>Pig butchering</h2> 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. 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>. 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. 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. 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. 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. 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. When the victim runs out of money or tries to withdraw funds, they are blocked. 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. <h2>PayPal scams</h2> 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. 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. 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. 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>. <h2>The missing person scam</h2> 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>. 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. 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. <h2>Fake app alerts</h2> People post mobile apps, designed to steal users’ personal information, on the Google Play or Apple app store. 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. 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. 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. 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.<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/207759/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/stacey-wood-473147">Stacey Wood</a>, Professor of Psychology, <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>, Professor in Decision Science, <a href="https://theconversation.com/institutions/university-of-southampton-1093">University of Southampton</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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

<a href="https://theconversation.com/profiles/stefan-b-williams-1448728">Stefan B. Williams</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> 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. 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). 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. 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. <h2>OceanGate’s Titan submersible goes missing</h2> 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. 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. 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”. 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. 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. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/532840/original/file-20230620-23-c6k9lo.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/532840/original/file-20230620-23-c6k9lo.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&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&q=45&auto=format&w=600&h=413&fit=crop&dpr=1 600w, https://images.theconversation.com/files/532840/original/file-20230620-23-c6k9lo.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=413&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/532840/original/file-20230620-23-c6k9lo.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=413&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/532840/original/file-20230620-23-c6k9lo.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=518&fit=crop&dpr=1 754w, https://images.theconversation.com/files/532840/original/file-20230620-23-c6k9lo.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=518&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/532840/original/file-20230620-23-c6k9lo.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=518&fit=crop&dpr=3 2262w" alt="Several tube like shapes on a rectangular concrete platform underwater" /></a><figcaption>Titan on the launch platform underwater, awaiting a signal to commence the dive. <a class="source" href="https://oceangate.com/gallery/gallery-titan.html#nanogallery/titangallery/0/4">OceanGate</a></figcaption></figure> <h2>Communication and rescue efforts</h2> 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. 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. 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. 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. One of the major challenges in the rescue effort will be contending with weather conditions, which will further shrink an already narrow search window. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/532842/original/file-20230620-49349-cnzdk6.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/532842/original/file-20230620-49349-cnzdk6.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&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&q=45&auto=format&w=600&h=413&fit=crop&dpr=1 600w, https://images.theconversation.com/files/532842/original/file-20230620-49349-cnzdk6.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=413&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/532842/original/file-20230620-49349-cnzdk6.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=413&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/532842/original/file-20230620-49349-cnzdk6.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=518&fit=crop&dpr=1 754w, https://images.theconversation.com/files/532842/original/file-20230620-49349-cnzdk6.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=518&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/532842/original/file-20230620-49349-cnzdk6.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=518&fit=crop&dpr=3 2262w" alt="A dark blue image with a tube like shape floating in the lower third" /></a><figcaption>Titan commencing a dive to 4,000m underwater. <a class="source" href="https://oceangate.com/gallery/gallery-titan.html#nanogallery/titangallery/0/1">OceanGate</a></figcaption></figure> <h2>What might have happened?</h2> 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. Alternatively, the vessel may have lost power and ended up at the bottom of the ocean. This would be a more problematic outcome. 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. 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. 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. 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. 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" /> <a href="https://theconversation.com/profiles/stefan-b-williams-1448728">Stefan B.

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

<a href="https://theconversation.com/profiles/dylan-mcconnell-1602">Dylan McConnell</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> and <a href="https://theconversation.com/profiles/iain-macgill-576">Iain MacGill</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> 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. <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. 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. 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. <h2>How does hot weather affect energy supplies?</h2> 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. <figure class="align-center "><img src="https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&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&q=45&auto=format&w=600&h=208&fit=crop&dpr=1 600w, https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=208&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=208&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=262&fit=crop&dpr=1 754w, https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=262&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=262&fit=crop&dpr=3 2262w" alt="Scatterplot of New South Wales demand and temperature, example based on 2017 calendar year" /><figcaption>Scatterplot of New South Wales demand and temperature, example based on 2017 calendar year. AEMO</figcaption></figure> 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. 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. 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. 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. <h2>Other headwinds are blowing</h2> Aside from facing a likely El Niño, the electricity sector faces other headaches. 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. 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. 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. 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. But the operator also said delays to the Kurri Kurri project posed risks to reliability in NSW this summer. 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. Combine all this with a likely El Niño, and the electricity sector may be facing a challenging summer. <h2>El Niño years are not normal</h2> 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. On first blush, that sounds like good news. However, the way the assessment is derived may mask the real risk during El Niño periods. 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. 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. This won’t be properly reflected in the assessment. So the grid may be deemed reliable even though electricity supplies are under immense pressure. <figure class="align-center "><img src="https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&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&q=45&auto=format&w=600&h=450&fit=crop&dpr=1 600w, https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=450&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=450&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=566&fit=crop&dpr=1 754w, https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=566&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=566&fit=crop&dpr=3 2262w" alt="repair person climbs power pole" /><figcaption>The grid may be deemed reliable even though it’s under pressure. Shutterstock</figcaption></figure> <h2>What can be done?</h2> You might find all this news worrying. But there are measures and technologies in place to help reduce the risks. <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. 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. 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. 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. 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. 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.<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/207210/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/dylan-mcconnell-1602">Dylan McConnell</a>, Senior Research Associate, Renewable Energy & Energy Systems Analyst, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> and <a href="https://theconversation.com/profiles/iain-macgill-576">Iain MacGill</a>, Joint director, Collaboration on Energy and Environmental Markets, and Professor, School of Electrical Engineering and Telecommunications, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Social media snaps map the sweep of Japan’s cherry blossom season in unprecedented detail

In a <a href="https://www.sciencedirect.com/science/article/abs/pii/S0367253023001019#sec0024a">new study published in Flora</a>, we show how social media can be used for “incidental citizen science”. From photos posted to a social site, we mapped countrywide patterns in nature over a decade in relatively fine detail. Our case study was the annual spread of cherry blossom flowering across Japan, where millions of people view the blooming each year in a cultural event called “hanami”. The flowering spreads across Japan in a wave (“<a href="https://en.wikipedia.org/wiki/Cherry_blossom_front">sakura zensen</a>” or 桜前線) following the warmth of the arriving spring season. <figure class="align-center "><img src="https://images.theconversation.com/files/529000/original/file-20230530-15-mix84k.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/529000/original/file-20230530-15-mix84k.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=399&fit=crop&dpr=1 600w, https://images.theconversation.com/files/529000/original/file-20230530-15-mix84k.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=399&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/529000/original/file-20230530-15-mix84k.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=399&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/529000/original/file-20230530-15-mix84k.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=501&fit=crop&dpr=1 754w, https://images.theconversation.com/files/529000/original/file-20230530-15-mix84k.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=501&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/529000/original/file-20230530-15-mix84k.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=501&fit=crop&dpr=3 2262w" alt="ALT TEXT" /><figcaption>Celebrating the cherry blossom is a centuries-old tradition in Japan. Shutterstock</figcaption></figure> The <a href="https://en.wikipedia.org/wiki/Hanami">hanami festival</a> has been documented for centuries, and research shows climate change is making <a href="https://iopscience.iop.org/article/10.1088/1748-9326/ac6bb4">early blossoming more likely</a>. The advent of mobile phones – and social network sites that allow people to <a href="https://www.sciencedirect.com/science/article/abs/pii/S1574954116302321">upload photos tagged with time and location data</a> – presents a new opportunity to study how Japan’s flowering events are affected by seasonal climate. <h2>Why are flowers useful to understand how nature is being altered by climate change?</h2> Many flowering plants, including the cherry blossoms of Japan (Prunus subgenus Cerasus), require insect pollination. To reproduce, plant flowers bloom at optimal times to receive visits from insects like bees. Temperature is <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0200549">an important mechanism</a> for plants to trigger this flowering. <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1111/j.1461-0248.2008.01269.x">Previous research</a> has highlighted how climate change may create mismatches in space or time between the blooming of plants and the emergence of pollinating insects. <iframe id="rtiQ0" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/rtiQ0/2/" width="100%" height="400px" frameborder="0"></iframe> It has been difficult for researchers to map the extent of this problem in detail, as its study requires simultaneous data collection over large areas. The use of citizen science images deliberately, or incidentally, uploaded to social network sites enables <a href="https://en.wikipedia.org/wiki/Big_data">big data</a> solutions. <h2>How did we conduct our study?</h2> We collected images from Japan uploaded to <a href="https://www.flickr.com/">Flickr</a> between 2008 and 2018 that were tagged by users as “cherry blossoms”. We used computer vision techniques to analyse these images, and to provide sets of keywords describing their image content. Next, we automatically filtered out images appearing to contain content that the computer vision algorithms determined didn’t match our targeted cherry blossoms. For instance, many contained images of autumn leaves, another popular ecological event to view in Japan. 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. <h2>Checking the data</h2> 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? <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>Blossom dates calculated from social media images compare well with official data.

Upon further searching, we discovered that this “unexpected” seasonal bloom had also been noted in <a href="https://www.bbc.com/news/world-asia-45898333">mainstream media</a> in recent years. We thus confirmed that this is a real event, not an artefact of our study. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/528832/original/file-20230529-25-wonef0.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/528832/original/file-20230529-25-wonef0.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/528832/original/file-20230529-25-wonef0.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=450&fit=crop&dpr=1 600w, https://images.theconversation.com/files/528832/original/file-20230529-25-wonef0.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=450&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/528832/original/file-20230529-25-wonef0.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=450&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/528832/original/file-20230529-25-wonef0.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=566&fit=crop&dpr=1 754w, https://images.theconversation.com/files/528832/original/file-20230529-25-wonef0.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=566&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/528832/original/file-20230529-25-wonef0.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=566&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>Cherry blossom photographs from Flickr taken within Japan from 2008 to 2018 show an April peak as well as an unexpected smaller peak in November.

What are the long-term effects of quitting social media? Almost nobody can log off long enough to find out

<a href="https://theconversation.com/profiles/john-malouff-313652">John Malouff</a>, <a href="https://theconversation.com/institutions/university-of-new-england-919">University of New England</a> Being on social media has become synonymous with living in the 21st century. Year after year, we see new platforms and smarter algorithms roping us into highly addictive online worlds. Now, a growing number of people have noticed this trend and are actively making an effort to resist it. Anecdotally, a case can be made for quitting social media, and there are myriad reasons why someone might want to. But is there evidence that doing so is good for you in the long term? <h2>Drivers for quitting</h2> Although there are too many social media platforms to name, most people tend to think of the “big five”: Facebook, Twitter, Instagram, YouTube and TikTok. Research has found people have various reasons for quitting one or more of these apps. Many quit over concerns about negative impacts on their mental and physical health. For example, studies have shown adolescent girls in particular can experience negative body image as a result of viewing manipulated <a href="https://theconversation.com/we-have-all-heard-social-media-can-impact-womens-body-image-but-it-isnt-all-bad-205214">selfies on Instagram</a>. People also <a href="https://www.qscience.com/content/journals/10.5339/connect.2023.spt.3?crawler=true">choose to quit</a> due to disliking ads, feeling like they’re wasting time, or if they’re worried about their privacy. The question then is: does quitting social media resolve these concerns? <h2>Mixed research outcomes</h2> It’s difficult to determine whether there are clear and lasting benefits to quitting social media – and a look at the research explains why. <a href="https://www.tandfonline.com/doi/full/10.1080/17459435.2020.1817140">One 2020 study</a> found people who had quit social media saw improvements in their close relationships, and were pleased to be free of comparison with others. But some also said they <a href="https://www.tandfonline.com/doi/full/10.1080/17459435.2020.1817140">missed</a> the informational and entertainment aspects of it. In a <a href="https://www.researchgate.net/publication/328838624_No_More_FOMO_Limiting_Social_Media_Decreases_Loneliness_and_Depression">2018 study</a>, researchers assessed the psychological state of 143 American undergraduates before randomly assigning one group a daily ten-minute limit for Facebook, Instagram and Snapchat, per platform. Three weeks later, those who limited their social media use showed significantly lower levels of loneliness and depression. However, there was no significant effect on anxiety, self-esteem or wellbeing. And in <a href="https://journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0217743&fbclid=IwAR1oLvPyeJDwMhD4WlODKU1A360ttIcaV_tManJs1_qEr-VAVZPsD0xQjq0">one 2019 study</a> with 78 participants, half were asked to take a one-week break from Facebook and Instagram. To the researchers’ surprise, the users in this group who were generally active on social media experienced less positive psychological effects than those in the control group. With research findings painting several different pictures, it’s safe to say our relationship with social media – and how it affects us – is very complex. <h2>Research constraints</h2> There appear to be no published studies that have assessed the long-term impacts of permanently quitting social media. This is probably because it’s difficult to find participants who will agree to be randomly assigned the task of dropping social media forever. One important consideration is that a percentage of individuals who quit social media will eventually <a href="https://cyberleninka.org/article/n/992039/viewer">go back</a>. Reasons for returning include feeling left out, fearing loss of connections, wanting to regain access to interesting or useful information, feeling social pressure to rejoin, or simply feeling that quitting wasn’t the right choice. Even if researchers do find a large enough group of people willing to quit social media for good, conducting long-term follow-ups would be highly resource-intensive. Beyond that, it would be difficult to figure out how much of a participant’s increase (or decrease) in life satisfaction is due to quitting social media, and not other factors. As such, there’s currently no evidence that quitting social media comes with concrete long-term benefits. And in the short term, results are mixed. <h2>To quit, or not to quit?</h2> However, that doesn’t mean quitting (for a short or long period) wouldn’t be beneficial for some people. It’s likely that any potential benefits will depend on the individual doing the quitting, and why they’re doing it. For instance, consensus that does emerge from the research is that <a href="https://theconversation.com/does-social-media-make-us-more-or-less-lonely-depends-on-how-you-use-it-128468">the way you use</a> social media plays a significant role in how negative or positive your experience is. By <a href="https://journals.sagepub.com/doi/pdf/10.1177/2056305120919105">using social media mindfully</a>, users can minimise potential harms while retaining the benefits. For some, it may only be one platform causing unease. If you strongly dislike Instagram’s tendency to be hyper-focused on people’s private lives, then you could simply stop using Instagram. Another technique is to curate your social media feeds by engaging only with content you find useful and positive. For instance, many young women take steps to avoid seeing <a href="https://theconversation.com/we-have-all-heard-social-media-can-impact-womens-body-image-but-it-isnt-all-bad-205214?fbclid=IwAR3cX7l116GAj0nnKDAk16x6GP6iRCxH_VutjIbxOiCij1yCqWmeOK0s0f0">perfect bodies all day</a> on their social media. If you’re still wondering whether quitting might be good for you, the simplest way to find out is to <a href="https://hbr.org/2018/10/i-ran-4-experiments-to-break-my-social-media-addiction-heres-what-worked">experiment</a> and do it. Take a break from one or more types of social media. After some time ask yourself whether the benefits seem worth it to you. If the answer is “yes”, make the break permanent. <a href="https://theconversation.com/profiles/john-malouff-313652">John Malouff</a>, Associate Professor, School of Behavioural, Cognitive and Social Sciences, <a href="https://theconversation.com/institutions/university-of-new-england-919">University of New England</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

6 amazing things you didn’t know your phone could do

Nobody ever bought a shiny brand new smartphone and then studiously read the manual! Maybe it’s just us but unfortunately it means we’ve missed out on the secret but amazing things your smartphone can do. You don't even need to download any apps to do these nifty tricks. Here are some of our favourite ones that we’re sure will impress next time you need them. Taking a screenshot A great trick if you want to share a hilarious text, picture or Facebook post with friends or family. iPhones – SImultaneously press (but not hold) the Home button and the Sleep/Wake button (top right of phone). You should hear a shutter click as well as see a white flash. The screenshot will be located on your Camera Roll in photos. Androids - Hold down the Power button and Volume -down button at the same time for a couple of seconds. Or hold down power button and home icon at the same time. If this doesn’t work, you can hold down the power button until the option to take a screen shot appears. Taking multiple photos at once A life-saver if you are taking pictures of wriggling kids or people who blink exactly when you take the picture (there’s always someone in the group isn’t there?). This little trick lets you take multiple pictures with a single click. iPhones – In the camera app, rather than tapping capture button to take photos, hold it down. Your camera will automatically take multiple picture (around 10 pictures a second) until you release the button. Androids - In the camera app, tap the gear icon and turn on “Burst Shot” settings. Return to your camera app and hold onto the capture button. Or go to camera, select mode, auto and click on burst shots. Change text size If the tiny text on the smartphone is giving you a headache, there’s an easily solution. You can change the settings so all text on your phone is large. iPhones - Go to Settings > General > Accessibility and turn on “Larger Text.” Androids - Go to Settings > Accessibility > Vision and tap font size and set it to Large. Read to you It really seems like technology can do anything, including programming your smartphone to read to you. iPhones - Go to Settings > General > Accessibility and turn on “Speak Selection.” You can even customise the voice that speaks to you choosing from a wide range of accent including Australian. To get your phone to speak to you, highlight text (double-tapping or tapping and holding on to it) and then tap Speak button in the pop-up menu. Turn off music automatically If you are one to listen to music or audiobooks as you drift off to sleep, you can use a timer to turn it off so it doesn’t drain your battery life. iPhones - Go to the Clock app and tap on "Timer," then "When Timer Ends." From here, scroll all the way down to the bottom of the screen and select "Stop Playing." Androids - Open the music player and go to Settings. Look for "Music auto off" and set it to however long you want the music to play. Search text messages Searching for messages is handy if you are looking for a specific text containing details like addresses, emails or dates. iPhones – When you open your Message app, scroll up and a search bar should pop up at the top of all your messages. Type in the phrase you are looking for. Androids – Open the Message app and then tap on the Menu. A few options will appear and click search. Image: Shutterstock
