Elderly woman reduced to tears by irate postie

<p>Australia Post is investigating an incident of extreme road rage, after a postie reduced an elderly woman to tears. </p> <p>The postman was driving a three-wheeled electric delivery vehicle on the Gold Coast on Monday morning, when an elderly woman almost struck him on a roundabout. </p> <p>The mailman then instructed the woman to pull over, and began berating her until she burst into tears.</p> <p>The altercation was filmed by a passerby, who attempted to intervene to assist the older woman, an 80-year-old named Kay.  </p> <p>“You’re supposed to give way at the roundabout,” the man is heard yelling in footage of the incident aired by <em>Nine News</em>. </p> <p><iframe style="border: none; overflow: hidden;" src="https://www.facebook.com/plugins/video.php?height=314&href=https%3A%2F%2Fwww.facebook.com%2F9NewsGoldCoast%2Fvideos%2F1680294369165021%2F&show_text=false&width=560&t=0" width="560" height="314" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe></p> <p>“You’re supposed to stop at the roundabout."</p> <p>“Why were you not seeing me?”</p> <p>Bystander Melissa Burrows ran to the aid of Kay, who was visibly upset by the altercation, with Burrows asking the postie to tone down his tirade. </p> <p>“She’s an older lady,” Ms Burrows is heard telling the postie. “She’s scared. Please stop.”</p> <p>“I didn’t see you,” Kay told the postie.</p> <p>Ms Burrows then threatens to call the police on the postie, who responds with a “go away”.</p> <p>“Leave her alone and let her go,” she said.</p> <p>“Can you just slow down next time, please?” the postie asks the elderly woman.</p> <p>“I’m so sorry I didn’t see you,” Kay reaffirms.</p> <p>Speaking to Melissa after the postie drove away, Kay said, “I didn’t even touch him, but I didn’t see him either. I can’t believe how he’s reacted.”</p> <p>Ms Burrows later told the broadcaster the incident was “absolutely horrifying” and a “tirade of incredible abuse”.</p> <p>Australia Post told <a href="https://www.news.com.au/technology/motoring/on-the-road/tirade-of-incredible-abuse-furious-postie-unleashes-on-elderly-gold-coast-driver/news-story/2c9985732e80970951aa73a6f03e1988" target="_blank" rel="noopener"><em>news.com.au</em></a> an investigation will be conducted reviewing video captured before and after the incident. </p> <p>“Australia Post’s Electric Delivery Vehicles (eDVs) are equipped with on-board telematics which capture video footage and data designed to help keep our people safe on the roads,” a spokesperson said.</p> <p><em>Image credits: Nine News</em></p>

How risky is it to give card details over the phone and how do I reduce the chance of fraud?

<p><em><a href="https://theconversation.com/profiles/paul-haskell-dowland-382903">Paul Haskell-Dowland</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> and <a href="https://theconversation.com/profiles/ismini-vasileiou-1031778">Ismini Vasileiou</a>, <a href="https://theconversation.com/institutions/de-montfort-university-1254">De Montfort University</a></em></p> <p>Paying for things digitally is so common, most of us think nothing of swiping or tapping our card, or using mobile payments. While doing so is second nature, we may be more reluctant to provide card details over the phone.</p> <p>Merchants are allowed to ask us for credit card details over the phone – this is perfectly legal. But there are minimum standards they must comply with and safeguards to protect consumer data.</p> <p>So is giving your card details over the phone any more risky than other transactions and how can you minimise the risks?</p> <h2>How is my card data protected?</h2> <p>For a merchant to process card transactions, they are expected to comply with the <a href="https://docs-prv.pcisecuritystandards.org/PCI%20DSS/Standard/PCI-DSS-v4_0.pdf">Payment Card Industry Data Security Standard</a>. This is a set of security requirements designed to protect cardholder data and the trillions of dollars of transactions each year.</p> <p>Compliance involves various security measures (such as encryption and access controls) together with strong governance and regular security assessments.</p> <p>If the information stored by the merchant is accessed by an unauthorised party, encryption ensures it is not readable. That means stealing the data would not let the criminals use the card details. Meanwhile, access controls ensure only authorised individuals have access to cardholder data.</p> <p>Though all companies processing cards are expected to meet the compliance standards, only those processing large volumes are subject to mandatory regular audits. Should a subsequent data leak or misuse occur that can be attributed to a compliance failure, a <a href="https://www.csoonline.com/article/569591/pci-dss-explained-requirements-fines-and-steps-to-compliance.html">company can be penalised</a> at levels that can escalate into millions of dollars.</p> <p>These requirements apply to all card transactions, whether in person, online or over the phone. Phone transactions are likely to involve a human collecting the card details and either entering them into computer systems, or processing the payment through paper forms. The payment card Security Standards Council has <a href="https://docs-prv.pcisecuritystandards.org/Guidance%20Document/Telephone-Based%20Payments/Protecting_Telephone_Based_Payment_Card_Data_v3-0_nov_2018.pdf">detailed guides for best practice</a>:</p> <blockquote> <p>A policy should be in place to ensure that payment card data is protected against unauthorised viewing, copying, or scanning, in particular on desks.</p> </blockquote> <p>Although these measures can help to protect your card data, there are still risks in case the details are misplaced or the person on the phone aren’t who they say they are.</p> <h2>Basic tips for safe credit card use over the phone</h2> <p>If you provide card details over the phone, there are steps you can take to minimise the chance you’ll become the victim of fraud, or get your details leaked.</p> <p><strong>1. Verify the caller</strong></p> <p>If you didn’t initiate the call, hang up and call the company directly using details you’ve verified yourself. Scammers will often masquerade as a well-known company (for example, an online retailer or a courier) and convince you a payment failed or payment is needed to release a delivery.</p> <p>Before you provide any information, confirm the caller is legitimate and the purpose of the call is genuine.</p> <p><strong>2. Be sceptical</strong></p> <p>If you are being offered a deal that’s too good to be true, have concerns about the person you’re dealing with, or just feel something is not quite right, hang up. You can always call them back later if the caller turns out to be legitimate.</p> <p><strong>3. Use secure payment methods</strong></p> <p>If you’ve previously paid the company with other (more secure) methods, ask to use that same method.</p> <p><strong>4. Keep records</strong></p> <p>Make sure you record details of the company, the representative you are speaking to and the amount being charged. You should also ask for an order or transaction reference. Don’t forget to ask for the receipt to be sent to you.</p> <p>Check the transaction against your card matches the receipt – use your banking app, don’t wait for the statement to come through.</p> <h2>Virtual credit cards</h2> <p>In addition to the safeguards mentioned above, a <a href="https://www.forbes.com/advisor/credit-cards/virtual-credit-card-numbers-guide/">virtual credit card</a> can help reduce the risk of card fraud.</p> <p>You probably already have a form of virtual card if you’ve added a credit card to your phone for mobile payments. Depending on the financial institution, you can create a new credit card number linked to your physical card.</p> <p>Some banks extend this functionality to allow you to generate unique card numbers and/or CVV numbers (the three digits at the back of your card). With this approach you can easily separate transactions and cancel a virtual card/number if you have any concerns.</p> <h2>What to do if you think your card details have been compromised or stolen?</h2> <p>It’s important not to panic, but quick action is essential:</p> <ul> <li> <p>call your bank and get the card blocked so you won’t lose any more money. Depending on your situation, you can also block/cancel the card through your banking app or website</p> </li> <li> <p>report the issue to the police or other relevant body</p> </li> <li> <p>monitor your account(s) for any unusual transactions</p> </li> <li> <p>explore card settings in your banking app or website – many providers allow you to limit transactions based on value, restrict transaction types or enable alerts</p> </li> <li> <p>you may want to consider registering for <a href="https://theconversation.com/your-credit-report-is-a-key-part-of-your-privacy-heres-how-to-find-and-check-it-116999">credit monitoring services</a> and to enable fraud alerts.</p> </li> </ul> <h2>So, should I give my card details over the phone?</h2> <p>If you want to minimise risk, it’s best to avoid giving card details over the phone if you can. Providing your card details via a website still has risks, but at least it removes the human element.</p> <p>The best solution currently available is to use virtual cards – if anything goes wrong you can cancel just that unique card identity, rather than your entire card.<!-- Below is The Conversation's page counter tag.

"32 years of safe landings": Pilot's surprise speech reduces passengers to tears

<p>A pilot has brought his passengers to tears with an emotional speech on his final flight after 32 years in the skies. </p> <p>Jeff Fell, an American Airlines pilot, took off from Chicago on his retirement flight as he stood in front of his passengers and delivered a heartfelt message. </p> <p>At first, his message seemed routine, informing travellers of the weather and and flight time, before acknowledging it was strange for him to deliver the address from outside the cockpit. </p> <p>“I normally don’t stand up in front of everybody like this, I usually just stay in the cockpit and talk on the PA. If I get a little emotional please forgive me for that,” he said in the speech, which was captured on video by a passenger. </p> <p>With passengers still unaware of what was to come, he pointed out a group of “very important people” to him sitting at the back of the plane.</p> <p>“They’re the majority of my family who have come along with me on my retirement flight,” Mr Fell said.</p> <p>The plane was filled with applause as the pilot's voice wavered with emotion.</p> <p>“They’re on-board with me on my retirement flight after 32 years with American,” he said.</p> <p>He continued, fighting back tears, “Thank you all for coming along with me tonight and celebrating this very memorable time in my life. I love all of you."</p> <p>With another round of applause from his passengers, Mr Fell added:, “I didn’t want to get emotional but goodness gracious.”</p> <p>“Finally, for my wonderful wife Julie who has been at my side for the majority of my 32 years at American. She has been the rock, the solid rock in the foundation in our lives and our marriage. Her faith in the Lord, wisdom, strength and love has guided our marriage and family throughout these years. I love you and look forward to the next chapter in our lives. And welcome aboard everybody.”</p> <p>The video was uploaded to TikTok and has since gone viral, raking up millions of views, and you can watch the full video <a href="https://www.tiktok.com/@realjharrison/video/7299484162648509738" target="_blank" rel="noopener">here</a>. </p> <p>Thousands of social media users left comments of support, with many confessing the clip had brought them to tears.</p> <p>“As soon as he said retirement flight my tears came,” one person wrote, while another added, "32 years of safe landings also. God bless him and all pilots.”</p> <p>“To think of the amount of families, people, and cultures he has single-handedly connected throughout the world. Thank you!” penned a third person.</p> <p>“32 years of bringing people closer together. I’m crying!” agreed another.</p> <p><em>Image credits: TikTok</em></p>

How do stimulants actually work to reduce ADHD symptoms?

<p><em><a href="https://theconversation.com/profiles/mary-bushell-919262">Mary Bushell</a>, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a></em></p> <p>Stimulants are <a href="https://adhdguideline.aadpa.com.au/">first-line drugs</a> for children and adults diagnosed with attention-deficit hyperactivity disorder (ADHD). But how do they actually work?</p> <h2>First, let’s look at the brain</h2> <p>ADHD is a neurodevelopmental condition, which means it affects how the brain functions.</p> <p>Medical imaging indicates people with ADHD may have slight differences in their brain’s <a href="https://jamanetwork.com/journals/jama/article-abstract/195386">structure</a>, the way their brain regions work together to perform tasks, and how their brain’s chemical messengers, called neurotransmitters, pass on information.</p> <p>These brain differences are associated with the symptoms of ADHD, including inattention, impulse control and problems with memory.</p> <h2>What stimulants are prescribed in Australia?</h2> <p>The three main stimulants prescribed for ADHD in Australia are dexamfetamine, methylphenidate (sold under the brand names Ritalin and Concerta) and lisdexamfetamine (sold as Vyvanse).</p> <p>Dexamfetamine and methylphenidate have been around <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3666194/">since</a> the 1930s and 1940s respectively. Lisdexamfetamine is a newer stimulant that has been around <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2873712/">since</a> the late 2000s.</p> <p>Dexamfetamine and lisdexamfetamine are amphetamines. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2873712/">Lisdexamfetamine</a> is inactive when it’s taken and actually changes into active dexamfetamine in the red blood cells. This is what’s known as a “prodrug”.</p> <h2>So how do they work for ADHD?</h2> <p>Stimulant drugs are thought to alter the activity of key neuotransmitters, dopamine and noradrenaline, in the brain. These neurotransmitters help with attention and focus, among other things.</p> <p>Stimulants increase the amount of dopamine and noradrenaline in the tiny gaps between neurons, known as synapses. They do this by predominantly blocking a transporter that then prevents their re-uptake back into the neuron that released them.</p> <p>This means more dopamine and noradrenaline can bind to their respective receptors. This <a href="https://www.tga.gov.au/sites/default/files/auspar-lisdexamfetamine-dimesilate-180515-pi.pdf">helps</a> connected neurons in the brain talk to one another.</p> <p>Amphetamines also increase the amount of dopamine the neuron releases into the synapse (the tiny gaps between neurons). And it stops the enzymes that break down dopamine. This results in an increase of dopamine in the synapse.</p> <h2>What effect do they have on ADHD symptoms?</h2> <p>We still don’t fully understand the underlying brain mechanisms that change behaviour in people with ADHD.</p> <p>But <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6109107/">research shows</a> stimulants that modulate noradrenaline and dopamine can improve brain processes such as:</p> <ul> <li>attention</li> <li>memory</li> <li>decision-making</li> <li>task completion</li> <li>hyperactivity.</li> </ul> <p>They can also improve general behaviour, such as self-control, not talking over the top of others, and concentration. These behaviours are important for social interactions.</p> <p>Stimulants <a href="https://pubmed.ncbi.nlm.nih.gov/15737659/">reduce ADHD symptoms</a> in about 70% to 80% of children and adults who take them.</p> <p>Some people will notice their symptoms improve right away. Other times, these improvements will be more noticeable to parents, carers, teachers, colleagues and partners.</p> <h2>Not everyone gets the same dose</h2> <p>The optimal stimulant dose varies between individuals, with multiple dosage options available.</p> <p>This enables a “start low, go slow” approach, where the stimulant can be gradually increased to the most effective dose for the individual.</p> <p>There are also different delivery options.</p> <p>Dexamfetamine and methylphenidate are available in immediate-release preparations. As these have short half-lives (meaning they act quickly and wear off rapidly), they are often taken multiple times a day – usually in the morning, lunch and afternoon.</p> <p>Methylphenidate is also <a href="https://www.ebs.tga.gov.au/ebs/picmi/picmirepository.nsf/pdf?OpenAgent&amp;id=CP-2010-PI-03175-3&amp;d=20231023172310101">available</a> in long-acting tablets (Concerta) and capsules (Ritalin LA). They are released into the body over the day.</p> <p>Lisdexamfetamine is a long-acting drug and is not available in a short-acting formulation.</p> <p>The long-acting stimulants are generally taken once in the morning. This avoids the need to take tablets during school or work hours (and the need to store a “controlled drug”, which has the potential for abuse, outside the home).</p> <h2>What are the side effects?</h2> <p>The most common side effects are sleep problems and decreased appetite. A <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD012069.pub2/full">recent study</a> showed children and young people taking methylphenidate for ADHD were around 2.6 times more likely to have sleep problems and 15 times more likely to have a decreased appetite than those not taking methylphenidate.</p> <p>Headache and abdominal pain are also relatively common.</p> <h2>Can someone without ADHD take a stimulant to improve productivity?</h2> <p>Stimulants are tightly controlled because of their potential for abuse. In Australia, only paediatricians, psychiatrists or neurologists (and GPs in special circumstances) can prescribe them. This follows a long assessment process.</p> <p>As stimulants increase dopamine, they can cause euphoria and a heightened sense of wellbeing. They can also cause <a href="https://www.ncbi.nlm.nih.gov/books/NBK576548/#:%7E:text=The%20immediate%20psychological%20effects%20of,and%20may%20result%20in%20insomnia.">weight loss</a>.</p> <p>A common myth about stimulant medicines is they can improve the concentration and productivity of people without ADHD. A <a href="https://www.science.org/doi/full/10.1126/sciadv.add4165">recent study shows</a> the opposite is true.</p> <p>This study gave a group of 40 people online arithmetic tasks to complete across four sessions. At each of the sessions, participants were given either a placebo or a stimulant before completing the task.</p> <p>The results showed that while stimulants did not impact getting the correct answer, it increased the number of moves and time to solve the problems compared to a placebo. This indicates a reduction in productivity.</p> <p>However, the myth that stimulants improve study prevails. It’s likely that users feel different – after all, they are taking a medicine that speeds up messages between the brain and body. It may make them “feel” more alert and productive, even if they’re not.<!-- Below is The Conversation's page counter tag.

How 22 minutes of exercise a day could reduce the health risks from sitting too long

<p><em><a href="https://theconversation.com/profiles/matthew-ahmadi-1241767">Matthew Ahmadi</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/emmanuel-stamatakis-161783">Emmanuel Stamatakis</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>People in developed countries spend an average of <a href="https://doi.org/10.1136/bjsports-2022-106568">nine to ten hours</a> a day sitting. Whether it’s spending time in front of a computer, stuck in traffic, or unwinding in front of the TV, our lives have become increasingly sedentary.</p> <p>This is concerning because prolonged time spent sitting is <a href="https://bjsm.bmj.com/content/54/24/1451?s=09&amp;int_source=trendmd&amp;int_medium=cpc&amp;int_campaign=usage-042019">linked to a number of health issues</a> including obesity, heart disease, and certain types of cancers. These health issues can contribute to earlier death.</p> <p>But a <a href="https://doi.org/10.1136/bjsports-2022-106568">new study</a> suggests that for people over 50, getting just 22 minutes of exercise a day can lower the increased risk of premature death from a highly sedentary lifestyle.</p> <h2>What the researchers did</h2> <p>The team combined data from two studies from Norway, one from Sweden and one from the United States. The studies included about 12,000 people aged 50 or older who wore wearable devices to track how active and sedentary they were during their daily routines.</p> <p>Participants were followed up for at least two years (the median was 5.2 years) during the study period, which spanned 2003-2020.</p> <p>Analyses took several lifestyle and health factors into account, such as education, alcohol intake, smoking status, and previous history of heart disease, cancer and diabetes. All this data was linked to national death registries.</p> <h2>A 22 minute threshold</h2> <p>A total of 805 participants died during follow up. The researchers found people who were sedentary for more than 12 hours a day had the highest risk of death (a 38% higher risk than people who were sedentary for eight hours).</p> <p>However, this was only observed in those who did less than 22 minutes of moderate to vigorous physical activity daily. So for people who did more than 22 minutes of exercise, there was no longer a significantly heightened risk – that is, the risk became generally similar to those who were sedentary for eight hours.</p> <p>Higher daily duration of physical activity was consistently associated with lower risk of death, regardless of total sedentary time. For example, the team reported an additional ten minutes of moderate to vigorous physical activity each day could lower mortality risk by up to 15% for people who were sedentary less than 10.5 hours a day. For those considered highly sedentary (10.5 hours a day or more), an additional ten minutes lowered mortality risk by up to 35%.</p> <h2>The study had some limitations</h2> <p>The team couldn’t assess how changes in physical activity or sedentary time over several months or years may affect risk of death. And the study included only participants aged 50 and above, making results less applicable to younger age groups.</p> <p>Further, cultural and lifestyle differences between countries may have influenced how data between studies was measured and analysed.</p> <p>Ultimately, because this study was observational, we can’t draw conclusions on cause and effect with certainty. But the results of this research align with a growing body of evidence exploring the relationship between physical activity, sedentary time, and death.</p> <h2>It’s positive news</h2> <p>Research has previously suggested <a href="https://bjsm.bmj.com/content/54/24/1499">physical activity may offset</a> health risks associated with <a href="https://www.jacc.org/doi/abs/10.1016/j.jacc.2019.02.031">high sedentary time</a>.</p> <p>The good news is, even short bouts of exercise can have these positive effects. In this study, the 22 minutes wasn’t necessarily done all at once. It was a total of the physical activity someone did in a day, and would have included incidental exercise (activity that’s part of a daily routine, such as climbing the stairs).</p> <p>Several studies using wearable devices have found short bursts of high-intensity everyday activities such as stair climbing or energetic outdoor home maintenance activities such as mowing the lawn or cleaning the windows can lower <a href="https://www.nature.com/articles/s41591-022-02100-x">mortality</a>, <a href="https://academic.oup.com/eurheartj/article/43/46/4801/6771381">heart disease</a> and <a href="https://jamanetwork.com/journals/jamaoncology/fullarticle/2807734">cancer</a> risk.</p> <p>A recent study using wearable devices found moderate to vigorous bouts of activity <a href="https://www.thelancet.com/journals/lanpub/article/PIIS2468-2667(23)00183-4/fulltext">lasting three to five minutes</a> provide similar benefits to bouts longer than ten minutes when it comes to stroke and heart attack risk.</p> <p>Several other studies have found <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2596007">being active just on the weekend</a> provides similar health benefits as <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2794038">being active throughout the week</a>.</p> <p>Research has also shown the benefits of <a href="https://jamanetwork.com/journals/jamaneurology/fullarticle/2795819">physical activity</a> and <a href="https://jamanetwork.com/journals/jama/article-abstract/2809418">reducing sedentary time</a> extend to cognitive health.</p> <p>Routines such as desk jobs can foster a sedentary lifestyle that may be difficult to shift. But mixing short bursts of activity into our day can make a significant difference towards improving our health and longevity.</p> <p>Whether it’s a brisk walk during lunch, taking the stairs, or even a short at-home workout, this study is yet another to suggest that every minute counts.<!-- Below is The Conversation's page counter tag.

We found 3 types of food wasters, which one are you?

<p><em><a href="https://theconversation.com/profiles/trang-nguyen-1454838">Trang Nguyen</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> and <a href="https://theconversation.com/profiles/patrick-oconnor-109973">Patrick O'Connor</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a></em></p> <p>Each year, Australian households discard about <a href="https://workdrive.zohopublic.com.au/external/06152b9ff5971843391f39fc4d32a847e56fb907c167a4a645887b0a4bc43000">2.5 million tonnes of food</a>. Most (73%) of this food waste <a href="https://www.sciencedirect.com/science/article/pii/S0959652622042081">ends up in landfill</a>.</p> <p>This is costly and contributes to <a href="https://pubmed.ncbi.nlm.nih.gov/37118273/">escalating greenhouse gas emissions</a>, because food waste rotting in landfill produces methane. So reducing household food waste and diverting it from landfill saves money, improves food security and benefits the environment.</p> <p>To address the problem, we need to understand how people generate and dispose of food waste. In <a href="https://doi.org/10.1016/j.foodqual.2023.105000">our new study</a>, we found households fell into three categories – based on the amount of food wasted, how much of that waste was avoidable and how it was sorted. These insights into consumer behaviour point to where the most worthwhile improvements can be made.</p> <figure><iframe src="https://www.youtube.com/embed/JvAFaD5f1Lo?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption></figcaption></figure> <h2>Three types of households</h2> <p>We conducted an online survey of 939 households in metropolitan Adelaide between April and May 2021.</p> <p>The sample closely matched the national Australian population in terms of gender, age and income.</p> <p>We asked about the types of food waste produced, the amount of food waste typically discarded in a week and motivations towards reducing and sorting food waste.</p> <p>We identified three distinct types of households:</p> <p><strong>Warriors</strong> are typically older and highly motivated to reduce and sort food waste. They generate minimal waste (9.6 litres per week), such as bones and vegetable peels, that is mostly unavoidable. This group comprised 39.6% of the sample.</p> <p><strong>Strugglers</strong> mainly consist of families with children who produce the largest amount of food waste (33.1 litres per week). They produce the highest proportion of avoidable food waste, such as uneaten fruits and vegetables, bread and cereals. They are moderately motivated to reduce and sort food waste, but more than half of their food waste still ends up in landfill. This group made up 19.6% of the sample.</p> <p><strong>Slackers</strong> are generally younger. They show little concern about reducing or sorting food waste. Slackers produce the smallest amount of food waste overall (9 litres a week), but the proportion of avoidable food waste (such as mixed leftovers) is significantly higher (38.9%) compared to warriors (24.5%). They are more than twice as likely to live in units, with 17.2% doing so, compared to just 7.8% of warriors. This group was 40.8% of the sample.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=361&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=361&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=361&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=454&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=454&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=454&amp;fit=crop&amp;dpr=3 2262w" alt="Graphic explainer showing the three types of households with their typical characteristics and food waste behaviours." /></a><figcaption><span class="caption">The three types of households with their typical characteristics and food waste behaviours.</span> <span class="attribution"><a class="source" href="https://doi.org/10.1016/j.foodqual.2023.105000">Trang Nguyen using Canva.com</a>, <a class="license" href="http://creativecommons.org/licenses/by-nc-nd/4.0/">CC BY-NC-ND</a></span></figcaption></figure> <h2>What can households do about their food waste?</h2> <p>Reducing household food waste involves changing behaviours in both food management (“upstream”) and waste management (“downstream”).</p> <p>Upstream measures aim to prevent food waste in the first place. For example, households can avoid buying or cooking too much food. Supporting households to plan and buy just the right amount of food is a great starting point.</p> <p>Once food waste has been produced, downstream measures come into play. The focus shifts to how we handle and dispose of this waste.</p> <p>When households engage in food waste recycling they <a href="https://doi.org/10.3390/su131911099">start thinking more</a> about their behaviour including purchasing and cooking.</p> <p>In Australia, food waste management is mainly the responsibility of local councils.</p> <p>There are three ways to target household food waste management and drive behavioural change:</p> <ul> <li> <p>providing kerbside collection of food organics and garden organics, also known as “FOGO”</p> </li> <li> <p>changing social norms around food waste</p> </li> <li> <p>offering economic incentives and disincentives.</p> </li> </ul> <h2>1. Providing a FOGO system</h2> <p>Councils should provide this option at a minimum. This ensures sufficient infrastructure is available to support motivated households to sort food waste.</p> <p>Unfortunately <a href="https://experience.arcgis.com/experience/e6b5c78e1dac47f88e7e475ffacfc49b">fewer than half of Australian councils</a> provide a garden organics system and only a quarter of councils provide a FOGO system.</p> <p>You can explore <a href="https://experience.arcgis.com/experience/e6b5c78e1dac47f88e7e475ffacfc49b">the FOGO interactive map</a> to see how your area stacks up.</p> <p><a href="https://www.greenindustries.sa.gov.au/resources/adelaide-metro-kerbside-waste-performance-report-2021-22">Most councils in metropolitan Adelaide</a> provide access to food waste recycling through the FOGO bin. But <a href="https://doi.org/10.1016/j.jclepro.2022.134636">our research</a> indicates more than half of household food waste still ends up in landfill. So we need additional programs to promote more sustainable behaviours.</p> <h2>2. Changing social norms</h2> <p>Social norms, the unspoken rules about what behaviours are deemed appropriate, can drive behavioural change.</p> <p>Examples of promoting social norms around food waste reduction include a <a href="https://www.stopfoodwaste.com.au/stop-food-waste-nationwide-consumer-campaign-summit-communique/">nationwide consumer campaign</a> on stopping food waste and the <a href="https://www.cityofadelaide.com.au/resident/recycling-waste/kitchen-caddies/">kitchen caddy</a> for benches to increase convenience for collecting food waste.</p> <p>But our research suggests some groups, like slackers, remain unmotivated without additional incentives. Economic incentives might motivate this group to engage in more sustainable behaviours.</p> <h2>3. Economic incentives</h2> <p>Currently, Australians pay for waste management through their council rates. This is a “pay-as-you-own” system.</p> <p>The cost is determined by the property’s value, regardless of the amount of waste generated. Renters indirectly contribute to this cost by paying rent.</p> <p>Neither owner-occupiers nor renters have any incentive to reduce waste generation when the cost is levied on property value rather than the amount of waste.</p> <p>An alternative approach gaining momentum in other parts of the world is the “pay-as-you-throw” approach, such as <a href="https://www.collectors2020.eu/wcs-ppw/stockholm-se/">Stockholm</a> and <a href="https://pocacito.eu/sites/default/files/WasteCharging_Taipei.pdf">Taipei</a>. This system charges households based on the weight of their waste, usually the general waste that needs to be discarded in landfill, while the collection of food waste and other recyclables remains free to encourage waste sorting.</p> <p>Recent <a href="https://doi.org/10.1016/j.jclepro.2023.137363">research</a> in Italy shows pay-as-you-throw schemes result in significant reductions in both the quantity of waste and costs associated with waste disposal in many Italian municipalities.</p> <p>The reduced costs flow on to savings for councils that could potentially reduce waste management fees passed on to homeowners and renters through council rates. Giving households incentives to reduce waste and find alternatives to disposal encourages residents to place a higher value on food that may otherwise be sent to landfill.</p> <h2>Reducing food waste is a win-win</h2> <p>Tackling food waste is a win-win for people and the planet. It’s worth using various approaches to encourage people to change their behaviour.</p> <p>Our findings can help inform the design of interventions aimed at reducing and sorting food waste in specific segments of the Australian population.<!-- Below is The Conversation's page counter tag.

Do blue-light glasses really work? Can they reduce eye strain or help me sleep?

<p><em><a href="https://theconversation.com/profiles/laura-downie-1469379">Laura Downie</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p>Blue-light glasses are said to <a href="https://www.baxterblue.com.au/collections/blue-light-glasses">reduce eye strain</a> when using <a href="https://www.blockbluelight.com.au/collections/computer-glasses">computers</a>, improve your <a href="https://www.ocushield.com/products/anti-blue-light-glasses">sleep</a> and protect your eye health. You can buy them yourself or your optometrist can prescribe them.</p> <p>But <a href="https://mivision.com.au/2019/03/debate-continues-over-blue-blocking-lenses/">do they work</a>? Or could they do you harm?</p> <p>We <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013244.pub2/full">reviewed</a> the evidence. Here’s what we found.</p> <h2>What are they?</h2> <p>Blue-light glasses, blue light-filtering lenses or blue-blocking lenses are different terms used to describe lenses that reduce the amount of short-wavelength visible (blue) light reaching the eyes.</p> <p>Most of these lenses prescribed by an optometrist decrease blue light transmission by <a href="https://onlinelibrary.wiley.com/doi/10.1111/opo.12615">10-25%</a>. Standard (clear) lenses do not filter blue light.</p> <p>A wide variety of lens products are available. A filter can be added to prescription or non-prescription lenses. They are widely marketed and are becoming <a href="https://onlinelibrary.wiley.com/doi/10.1111/opo.12615">increasingly popular</a>.</p> <p>There’s often an added cost, which depends on the specific product. So, is the extra expense worth it?</p> <h2>Blue light is all around us</h2> <p>Outdoors, sunlight is the main source of blue light. Indoors, light sources – such as light-emitting diodes (LEDs) and the screens of digital devices – emit varying degrees of blue light.</p> <p>The amount of blue light emitted from artificial light sources is much lower than from the Sun. Nevertheless, artificial light sources are all around us, at home and at work, and we can spend a lot of our time inside.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=3 2262w" alt="Blue light-filtering lenses block some blue light from screens from reaching the eye" /></a><figcaption><span class="caption">Screens emit blue light.

So we conducted a <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013244.pub2/full">systematic review</a> to bring together and evaluate all the relevant studies.</p> <p>We included all randomised controlled trials (clinical studies designed to test the effects of interventions) that evaluated blue light-filtering lenses in adults. We identified 17 eligible trials from six countries, involving a total of 619 adults.</p> <h2>Do they reduce eye strain?</h2> <p>We found no benefit of using blue light-filtering lenses, over standard (clear) lenses, to reduce eye strain with computer use.</p> <p>This conclusion was based on consistent findings from three studies that evaluated effects on eye strain over time periods ranging from two hours to five days.</p> <h2>Do they help you sleep?</h2> <p>Possible effects on sleep were uncertain. Six studies evaluated whether wearing blue-light filtering lenses before bedtime could improve sleep quality, and the findings were mixed.</p> <p>These studies involved people with a diverse range of medical conditions, including insomnia and bipolar disorder. Healthy adults were not included in the studies. So we do not yet know whether these lenses affect sleep quality in the general population.</p> <h2>Do they boost your eye health?</h2> <p>We did not find any clinical evidence to support using blue-light filtering lenses to protect the macula (the region of the retina that controls high-detailed, central vision).</p> <p>None of the studies evaluated this.</p> <h2>Could they do harm? How about causing headaches?</h2> <p>We could not draw clear conclusions on whether there might be harms from wearing blue light-filtering lenses, compared with standard (non blue-light filtering) lenses.</p> <p>Some studies described how study participants had headaches, lowered mood and discomfort from wearing the glasses. However, people using glasses with standard lenses reported similar effects.</p> <h2>What about other benefits or harms?</h2> <p>There are some important general considerations when interpreting our findings.</p> <p>First, most of the studies were for a relatively short period of time, which limited our ability to consider longer-term effects on vision, sleep quality and eye health.</p> <p>Second, the review evaluated effects in adults. We don’t yet know if the effects are different for children.</p> <p>Finally, we could not draw conclusions about the possible effects of blue light-filtering lenses on many vision and eye health measures, including colour vision, as the studies did not evaluate these.</p> <h2>In a nutshell</h2> <p>Overall, based on relatively limited published clinical data, our review does not support using blue-light filtering lenses to reduce eye strain with digital device use. It is unclear whether these lenses affect vision quality or sleep, and no conclusions can be drawn about any potential effects on the health of the retina.</p> <p>High-quality research is needed to answer these questions, as well as whether the effectiveness and safety of these lenses varies in people of different ages and health status.</p> <p>If you have eye strain, or other eye or vision concerns, discuss this with your optometrist. They can perform a thorough examination of your eye health and vision, and discuss any relevant treatment options.<!-- Below is The Conversation's page counter tag.

<p><em><a href="https://theconversation.com/profiles/peter-osullivan-48973">Peter O'Sullivan</a>, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a>; <a href="https://theconversation.com/profiles/jp-caneiro-1463060">JP Caneiro</a>, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a>; <a href="https://theconversation.com/profiles/mark-hancock-1463059">Mark Hancock</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a>, and <a href="https://theconversation.com/profiles/peter-kent-1433302">Peter Kent</a>, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a></em></p> <p>If you haven’t had lower back pain, it’s likely you know someone who has. It affects <a href="https://pubmed.ncbi.nlm.nih.gov/22231424/">around 40% of adults</a> in any year, ranging from adolescents to those in later life. While most people recover, <a href="https://pubmed.ncbi.nlm.nih.gov/29112007/">around 20%</a> go on to develop chronic low back pain (lasting more than three months).</p> <p>There is a <a href="https://bjsm.bmj.com/content/54/12/698">common view</a> that chronic low back pain is caused by permanent tissue damage including “wear and tear”, disc degeneration, disc bulges and arthritis of the spine. This “damage” is often described as resulting from injury and loading of the spine (such as bending and lifting), ageing, poor posture and weak “core” muscles.</p> <p>We’re often told to “protect” our back by sitting tall, bracing the core, keeping a straight back when bending and lifting, and avoiding movement and activities that are painful. Health practitioners often <a href="https://theconversation.com/having-good-posture-doesnt-prevent-back-pain-and-bad-posture-doesnt-cause-it-183732">promote and reinforce these messages</a>.</p> <p>But this is <a href="https://bjsm.bmj.com/content/54/12/698">not based on evidence</a>. An emerging treatment known as <a href="https://pubmed.ncbi.nlm.nih.gov/29669082/">cognitive functional therapy</a> aims to help patients undo some of these unhelpful and restrictive practices, and learn to trust and move their body again.</p> <h2>People are often given the wrong advice</h2> <p>People with chronic back pain are often referred for imaging scans to detect things like disc degeneration, disc bulges and arthritis.</p> <p>But these findings are very common in people <em>without</em> low back pain and research shows they <a href="https://pubmed.ncbi.nlm.nih.gov/24276945/">don’t accurately predict</a> a person’s current or future experience of pain.</p> <p>Once serious causes of back pain have been ruled out (such as cancer, infection, fracture and nerve compression), there is <a href="https://pubmed.ncbi.nlm.nih.gov/27745712/">little evidence</a> scan findings help guide or improve the care for people with chronic low back pain.</p> <p>In fact, scanning people and telling them they have arthritis and disc degeneration can <a href="https://pubmed.ncbi.nlm.nih.gov/33748882/">frighten them</a>, resulting in them avoiding activity, worsening their pain and distress.</p> <p>It can also lead to potentially harmful treatments such as <a href="https://pubmed.ncbi.nlm.nih.gov/27213267/">opioid</a> pain medications, and invasive treatments such as spine <a href="https://pubmed.ncbi.nlm.nih.gov/19127161/">injections</a>, spine <a href="https://pubmed.ncbi.nlm.nih.gov/12709856/">surgery</a> and battery-powered electrical stimulation of spinal nerves.</p> <h2>So how should low back pain be treated?</h2> <p>A complex range of factors <a href="https://pubmed.ncbi.nlm.nih.gov/29112007/">typically contribute</a> to a person developing chronic low back pain. This includes over-protecting the back by avoiding movement and activity, the belief that pain is related to damage, and negative emotions such as pain-related fear and anxiety.</p> <p>Addressing these factors in an individualised way is <a href="https://pubmed.ncbi.nlm.nih.gov/29573871/">now considered</a> best practice.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/15936976/">Best practice care</a> also needs to be person-centred. People suffering from chronic low back pain want to be heard and validated. They <a href="https://pubmed.ncbi.nlm.nih.gov/35384928/">want</a> to understand why they have pain in simple language.</p> <p>They want care that considers their preferences and gives a safe and affordable pathway to pain relief, restoring function and getting back to their usual physical, social and work-related activities.</p> <p>An example of this type of care is cognitive functional therapy.</p> <h2>What is cognitive functional therapy?</h2> <p><a href="https://pubmed.ncbi.nlm.nih.gov/29669082/">Cognitive functional therapy</a> is about putting the person in the drivers’ seat of their back care, while the clinician takes the time to guide them to develop the skills needed to do this. It’s led by physiotherapists and can be used once serious causes of back pain have been ruled out.</p> <p>The therapy helps the person understand the unique contributing factors related to their condition, and that pain is usually not an accurate sign of damage. It guides patients to relearn how to move and build confidence in their back, without over-protecting it.</p> <p>It also addresses other factors such as sleep, relaxation, work restrictions and engaging in physical activity based on the <a href="https://www.restorebackpain.com/patient-journey">person’s preferences</a>.</p> <p>Cognitive functional therapy usually involves longer physiotherapy sessions than usual (60 minutes initially and 30-45 minute follow-ups) with up to seven to eight sessions over three months and booster sessions when required.</p> <h2>What’s the evidence for this type of therapy?</h2> <p>Our recent clinical trial of cognitive functional therapy, published in <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(23)00441-5/fulltext">The Lancet</a>, included 492 people with chronic low back pain. The participants had pain for an average of four years and had tried many other treatments.</p> <p>We first trained 18 physiotherapists to competently deliver cognitive functional therapy across Perth and Sydney over six months. We compared the therapy to the patient’s “usual care”.</p> <p>We found large and sustained improvements in function and reductions in pain intensity levels for people who underwent the therapy, compared with those receiving usual care.</p> <p>The effects remained at 12 months, which is unusual in low back pain trials. The effects of most recommended interventions such as exercise or psychological therapies are <a href="https://pubmed.ncbi.nlm.nih.gov/34580864/">modest in size</a> and tend to be of <a href="https://pubmed.ncbi.nlm.nih.gov/32794606/">short duration</a>.</p> <p>People who underwent cognitive functional therapy were also more confident, less fearful and had a more positive mindset about their back pain at 12 months. They also liked it, with 80% of participants satisfied or highly satisfied with the treatment, compared with 19% in the usual care group.</p> <p>The treatment was as safe as usual care and was also cost-effective. It saved more than A$5,000 per person over a year, largely due to increased participation at work.</p> <h2>What does this mean for you?</h2> <p>This trial shows there are safe, relatively cheap and effective treatments options for people living with chronic pain, even if you’ve tried other treatments without success.</p> <p><a href="https://www.restorebackpain.com/cft-clinicians">Access to clinicians</a> trained in cognitive functional therapy is currently limited but will expand as training is scaled up.</p> <p>The costs depend on how many sessions you have. Our studies show some people improve a lot within two to three sessions, but most people had seven to eight sessions, which would cost around A$1,000 (aside from any Medicare or private health insurance rebates). <!-- Below is The Conversation's page counter tag.

"Heartbreaking" issue set to engulf Bali

<p>A viral video has shown the devastating side of tourism in Bali, with mountains of garbage taking over the popular holiday destination. </p> <p>Gary Bencheghib, a French filmmaker living in Indonesia, captured a heartbreaking video of a massive “open rubbish dump” 50 metres high covered in trash.</p> <p>He said it is one of many open dumps around Bali, which are overflowing with waste. </p> <p>“I’ve just made it here, right at the foot of this giant open landfill.

More than a game: Crosswords and puzzles may reduce dementia risk

<p>Playing games, doing crosswords, writing letters or learning something new are all associated with reduced dementia risk in older adults, according to a large, long-term study.</p> <p>A team of Melbourne and US-based researchers study tracked 10,318 older Australians over a period of ten years (2010 to 2020), collecting detailed information on the types of leisure activities they engaged in, along with regular health checks and cognitive assessments.</p> <p>The study is <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2807256" target="_blank" rel="noreferrer noopener">published</a> in <em>JAMA Network Open.</em></p> <p>Paper co-author Dr Joanne Ryan from Monash University says “the findings show that engaging in mentally stimulating activities can help preserve cognitive function and may help delay the onset of dementia.”</p> <p>“We know the importance of physical activity. We need to think about helping to keep our mind stimulated as well.”</p> <p><iframe title="Why do Women Live Longer than Men?

Ryan says this was a “little bit unexpected”. But she says it’s possible one of the reasons is those who volunteered to participate in the study were broadly already socially engaged. </p> <p>The median age of those participating in the study was 73.8 years. Around 2% of the cohort participating in the study developed dementia, Ryan says. </p> <p>Dementia risk varies depending on age and health status of individuals, she says.</p> <p>For instance, “we know that the risk of dementia actually increases exponentially as you get then over 80 years and over 90 years,” she says.</p> <p><em>Image credits: Getty Images </em></p> <div id="contributors"> <p><em><a href="https://cosmosmagazine.com/health/body-and-mind/more-than-a-game-crosswords-and-puzzles-may-reduce-dementia-risk/">This article</a> was originally published on <a href="https://cosmosmagazine.com">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/petra-stock">Petra Stock</a>. </em></p> </div>

15 great kitchen hacks to extend the life of food and save on waste

<p>If you’re sick of throwing food in the bin (and wasting money), try these simple tips to reduce your wastage in the kitchen.         </p> <p><strong>1. Use food scraps to grow vegetables</strong></p> <p>Save the odds and ends from veggies such as potatoes, sweet potatoes, leeks, spring onions, celery, bok choy, garlic and even onions. These can all be replanted in some soil and will grow back. Just don’t forget to water them.</p> <p><strong>2. Reheat leftover slices of pizza in a frying pan</strong></p> <p>If you aren’t a fan of floppy microwaved pizza, just pop your pizza into a hot fry pan instead. Your crusts will stay crispy and it will heat through much faster than it would in the oven.</p> <p><strong>3. Bring stale potato chips back to life in the microwave</strong></p> <p>If you left the bag open overnight, fear not. Pop your stale chips in the microwave on high for 10 seconds or until crisp.</p> <p><strong>4. Use leftover herbs to make herb butter</strong></p> <p>If your herbs are on the turn, just chop them up and mix with some melted butter. Pop it into some ice cube trays and freeze. Then you can enjoy the perfect portion of herb butter to use on your steak or to make homemade garlic bread.</p> <p><strong>5. Keep bananas fresher by wrapping the tips</strong></p> <p>If you want your bananas to last longer in the fruit bowl, just wrap their tips with some cling film. They should keep for around three to five days longer.</p> <p><strong>6. Keep greens fresher in foil</strong></p> <p>Celery, broccoli, and lettuce all last much longer in the fridge if you wrap them in foil first.</p> <p><strong>7. Keep pineapples sweet by storing upside down</strong></p> <p>The sugars in this fruit can all end up on the bottom after the time spent in transit. So keep your pineapple upside down when you get home and the sweetness will be redistributed evenly.</p> <p><strong>8. Use a glass to peel a mango</strong></p> <p>You can use a glass to slide the skin off your mango. This will avoid wasting any fruit that you’d normally toss after peeling with a knife.</p> <p><strong>9. Make a two-ingredient Nutella milkshake</strong></p> <p>When you need a sweet treat but you’re nearly out of Nutella, just add warm milk to the jar and shake well.</p> <p><strong>10. Avoid sprouting potatoes by storing them with apples</strong></p> <p>The ethylene gas in the apples helps to stop your potatoes from sprouting.</p> <p><strong>11. Keep leftover avocado fresh by storing it with a sliced onion</strong></p> <p>There is sulfur in the onion and this keeps the avocado from going brown.</p> <p><strong>12. Keep cake fresh by covering with sliced bread</strong></p> <p>Cover the exposed cake with some bread held in place with toothpicks and it will stay soft.</p> <p><strong>13. Extend the life of your eggs with vegetable oil</strong></p> <p>By rubbing the eggshells with vegetable oil it will keep them fresher in the fridge for three to four weeks.</p> <p><strong>14. Keep lettuce fresh by storing in a brown paper bag</strong></p> <p>No more sad and limp leaves! Keep your lettuce wrapped in a brown paper bag in the fridge. Plus, keeping the outer layers in place even if they have gone brown will keep the inside fresher for longer.</p> <p><strong>15. Reuse coffee grounds in the garden</strong></p> <p>Plants such as roses, hydrangeas, blueberries, raspberries, strawberries and tomatoes will all appreciate a liberal sprinkling of your used coffee grounds.</p> <p><em>Image credit: Shutterstock</em></p>

How ‘ugly’ fruit and vegetables could tackle food waste and solve supermarket supply shortages

<p>The world is facing a significant food waste problem, with <a href="https://www.fao.org/3/i4068e/i4068e.pdf">up to half of all fruit and vegetables</a> lost somewhere along the agricultural food chain. Globally, around <a href="https://www.fao.org/3/ca6030en/ca6030en.pdf">14% of food produced</a> is lost after harvesting but before it reaches shops and supermarkets.</p> <p>Alongside food prices (66%), food waste is a concern for 60% of people that participated in a <a href="https://www.food.gov.uk/research/food-and-you-2/food-and-you-2-wave-5">recent survey</a> published by the UK Food Standards Agency. <a href="https://publications.parliament.uk/pa/cm201617/cmselect/cmenvfru/429/429.pdf">Other research</a> suggests that as much as 25% of apples, 20% of onions and 13% of potatoes grown in the UK are destroyed because they don’t look right. This means that producers’ efforts to meet stringent specifications from buyers can lead to <a href="https://publications.parliament.uk/pa/cm201617/cmselect/cmenvfru/429/429.pdf">perfectly edible produce being discarded</a> before it even leaves the farm – simply because of how it looks.</p> <p>Aside from the ongoing environmental implications of this food waste, UK shoppers currently face <a href="https://www.theguardian.com/environment/2023/mar/04/food-tsar-blames-shortages-on-uks-weird-supermarket-culture">produce rationing in some supermarkets</a> due to <a href="https://www.cnbc.com/2023/02/28/british-supermarkets-are-rationing-fruit-and-vegetables-amid-shortages.html">shortages of items like tomatoes, cucumbers and raspberries</a>. Any solutions that increase locally grown produce on shop shelves could improve the availability of fresh food, particularly in urban areas.</p> <p>When imperfect fruit and vegetables don’t make it to supermarket shelves, it can be due to <a href="https://cases.open.ubc.ca/insistence-on-cosmetically-perfect-fruits-vegetables/">cosmetic standards</a>. Supermarkets and consumers often prefer produce of a fairly standard size that’s free of blemishes, scars and other imperfections. This means fruit and vegetables that are misshapen, discoloured, or even too small or too large, are rejected before they make it to supermarket shelves.</p> <p>In recent years there has been a growing trend of selling such “ugly” fruit and vegetables, both by <a href="https://my.morrisons.com/wonky-fruit-veg/">major</a> <a href="https://www.waitrose.com/ecom/content/sustainability/food-waste">supermarket</a> <a href="https://www.tescoplc.com/news/2021/wonky-veg-5th-anniversary/">chains</a>, as well as <a href="https://wonkyvegboxes.co.uk/">speciality</a> <a href="https://www.misfitsmarket.com/?exp=plans_rollback">retailers</a> that sell <a href="https://www.oddbox.co.uk/">boxes</a> of <a href="https://etepetete-bio.de/">wonky produce</a>. And research has shown that 87% of people say they would <a href="https://www.thegrocer.co.uk/fruit-and-veg/nearly-90-of-consumers-would-eat-wonky-fruit-and-veg-according-to-new-survey/670155.article">eat wonky fruit and vegetables if they were available</a>. But other research indicates consumers can still be picky and difficult to predict. One study <a href="https://www.sciencedirect.com/science/article/pii/S0950329316302002?via%3Dihub">showed</a> consumers are likely to throw away an apple with a spot, but would eat a bent cucumber.</p> <h2>Getting ugly produce into baskets</h2> <p>So how can producers and retailers boost the amount of non-standard fruit and veg that not only reaches our shelves, but also our plates? <a href="https://www.sciencedirect.com/science/article/pii/S0377221723000668">Our recent research</a> suggests a separate channel for selling ugly produce would increase profits for growers, lower prices for consumers and boost overall demand for produce.</p> <p>For growers, a dedicated channel – either independent or set up by a supermarket – to supply wonky fruit and veg creates a new line of business. For retailers, this provides an opportunity for further revenue over and above current sales of standard produce to shops. When selling both types of product to a single retailer, the ugly items might be undervalued compared with the standard-looking products. Our research also shows that selling the ugly produce through a dedicated channel is likely to increase total demand for fruit and vegetables, while also decreasing on-farm loss.</p> <p>Having two parallel channels for selling produce (the main one and the dedicated “ugly” channel) would increase competition. This benefits shoppers by lowering prices for regular and ugly produce, versus selling both types of products alongside each other in one shop.</p> <p>On the other hand, the growing market for ugly fruit and vegetables could be an economic threat to traditional retailers. It encourages new entrants into the market and could also limit the availability of “regular” produce because growers could become less stringent about ensuring produce meets traditional cosmetic standards.</p> <p>But there is a way for traditional retailers to add ugly produce into their product offerings alongside other produce without affecting their profits. By building on existing consumer awareness of the environmental benefits of ugly food, they could also compete in this growing segment. This would benefit their bottom lines and help consumer acceptance of misshapen fruit and vegetables, possibly leading to less food waste and shortages like those UK shoppers are experiencing right now.</p> <p>Boosting demand for imperfect fruit and vegetables across the supply chain will require all participants to get involved – from grower to seller. Here are some steps the various parties could take:</p> <h2>1. Educating consumers</h2> <p>Education about the environmental and economic impact of food waste could happen through marketing campaigns, in-store displays and even social media.</p> <h2>2. Reducing cosmetic standards</h2> <p>Supermarkets and other major food retailers could revise their cosmetic standards to accept a wider range of produce, including imperfect fruit and vegetables. This would help reduce food waste by making sure more produce is able to be sold.</p> <h2>3. Direct sales</h2> <p>Farmers and growers could sell non-standard produce directly to consumers through farmers’ markets or subscription services. This allows consumers to purchase fresh, locally grown produce that might not meet cosmetic standards for supermarkets but that is just as nutritionally beneficial.</p> <h2>4. Food donations</h2> <p>Supermarkets and growers could donate produce rejected for how it looks to food banks, shelters and other organisations that serve those in need. This would help reduce food waste while also providing healthy food to those who might not otherwise have access to it.</p> <h2>5. Value-added products</h2> <p>Produce that doesn’t meet cosmetic standards could also be used to create other products such as soups, sauces and juices. In addition to reducing food waste, this would create new revenue streams for growers and retailers.</p> <h2>6. Food composting</h2> <p>Anything that cannot be sold or otherwise used should be composted. This would help reduce food waste while also creating nutrient-rich soil for future crops.</p> <p>By implementing these solutions, the supply chain can reduce the amount of ugly or imperfect fruit and vegetables that are wasted, while also providing consumers with healthy, affordable produce, even in times of supply chain shortages.</p> <p><em>This article originally appeared on <a href="https://theconversation.com/how-ugly-fruit-and-vegetables-could-tackle-food-waste-and-solve-supermarket-supply-shortages-201216" target="_blank" rel="noopener">The Conversation</a>.</em></p> <p><em>Images: Getty</em></p>

10 things that are always a waste to pack

<p>All travellers know the hardships of packing the necessities for the trip ahead. And everyone knows how many things you haven’t actually used by the time you get home again – what a waste of precious space in your luggage.</p> <p>Here is a list of 10 things to not bother packing in your suitcase.</p> <p><strong>1. Shampoo and conditioner</strong></p> <p>You can purchase these items at the places you travel. If the locals have easy access to hair products then so will you. Hotels should provide little travel-sized minis which will last a few days. Travelling with liquids can also lead to delays at security check points.</p> <p><strong>2. Shoes</strong></p> <p>Don’t pack more than two pairs of shoes – they take up unnecessary weight and space. Ensure you have a comfortable pair of walking shoes and some shoes that are nice enough to go out in at restaurants and other events.</p> <p><strong>3. Jewellery</strong></p> <p>Don’t bring your favourite expensive jewellery, you are only human and can accidentally leave items behind in hotels or apartments. You could also increase your risk of becoming a target for pickpockets. Try swapping out your diamond earrings for some cheaper substitute studs while you’re away.</p> <p><strong>4. Laptop</strong></p> <p>Don’t bring your laptop. Unless you’re travelling for work, you probably don’t need to bring a computer on your holiday. You could also become a target for thieves while travelling if they notice you have an expensive technological device with you.</p> <p><strong>5. Swimming costume</strong></p> <p>Don’t bring more than two swimming costumes. They are easy to wash and having two on hand always ensures you have a dry one to wear for the next day. Just put the swimmers in the sink filled with cool water and add some mild detergent before rinsing and wringing out to dry.</p> <p><strong>6. Hair dryer </strong></p> <p>Hair dryers are heavy and bulky, so they aren’t the easiest thing to try and squeeze into your suitcase. Hairdryers are usually provided by hotels and although yours may be nicer, they both do the same job in the end.</p> <p><strong>7. Out of season clothing </strong></p> <p>Avoid packing out of season clothing – if you’re going on a summer holiday in Europe, you probably don’t need that heavy winter coat. The excuse for packing these unnecessary items is always “just in case,” but if the situation does arise where there is an uncharacteristic change in weather, you can always buy what you need to face the day.</p> <p><strong>8. Books </strong></p> <p>Turn to paperback books or electronic tablets instead of hardcover novels. The electronic tablets are most helpful as they can contain a whole library of book options without adding the weight of a library in your suitcase. Paperback books are good when you don’t have an electronic tablet, but maybe avoid packing seven books!</p> <p><strong>9. Traveller’s checks </strong></p> <p>Traveller’s checks aren’t used anymore. Although they were once the safeguard of money while on holidays, the traveller’s checks have gone out of style. It’s unlikely you will come across a place that will accept the checks, as these have been replaced by the use of ATMs for cash and the ability to use your debit and credit cards that don’t charge an international transaction fee.</p> <p><strong>10. Double-ups </strong></p> <p>Finally, don’t bring anything your travel partner is also packing. For instance, don’t pack more than one thing that can be shared. You don’t need two tubes of toothpaste, for instance!</p> <p><em>Images: Getty</em></p>

Ways you’re wasting money without knowing it

<p><strong>Airline fees</strong></p> <p>You’re paying extra for almost everything when you fly these days, from your bags to your seat. So be sure to compare not only the prices of flights but what they’re charging in extra fees. You may also want to weigh your bag before you go to avoid any additional charges.</p> <p><strong>Bank fees</strong></p> <p>Not keeping enough money in your bank account could cost you some serious cash. How much? ATM and other maintenance fees can also add up to $1,000 over ten years. To avoid them, look for banks with free ATMs that don’t charge monthly maintenance fees.</p> <p><strong>Buying things new</strong></p> <p>Sure, a shiny new car is tempting. But as soon as you drive it off the lot, the car loses 11 percent of its value. A better option? Opt for a reliable used car and a short-term loan you can pay off quickly. The same goes for electronics and other items.</p> <p><strong>Convenience foods</strong></p> <p>Pre-cut fruit and vegetables can save time, but they can also dent your wallet. Instead, buy food as close to its natural form as possible, and divide it up into portion sizes yourself.</p> <p>The same concept applies for all those fancy lattes. Even if you buy just three $5 drinks each week, that’s $780 per year. Over a decade, it’s $7,800.</p> <p><strong>Credit card interest</strong></p> <p>It’s not uncommon to be charged 20 percent annually, although some people face even steeper rates. If you carry $25,000 in debt, paying 20 percent on it will cost you a whopping $5,000 annually – just in interest. To avoid paying extra money for old debts, try the snowball method. Pay off the card with the lowest balance first, then move on to the next one.</p> <p><strong>Dry cleaning</strong></p> <p>A typical trip to the cleaners for your pants and shirts can cost you more than $10. With a weekly visit, that could add up to more than $500 per year. To save that money, clean your shirts in the delicate cycle in your washer or hand wash them.</p> <p><strong>Eating out</strong></p> <p>Going out to dinner with the family can be a nice treat, but doing it regularly really adds up. Instead of buying your lunch every day, save money by packing it. And before you go out, look for specials like coupons or happy hours or get entrees instead of full meals.</p> <p><strong>Extended warranties </strong></p> <p>Getting an extended warranty on that refrigerator or car you bought sounds like a good idea. But most extended warranties aren’t worth the money. Why? The fine print may not include likely problems, or you may be buying duplicate coverage. A better plan? Open a savings account and sock away money for any repairs that might come up.</p> <p><strong>Impulse buys</strong></p> <p>Spur-of-the-moment buys can cost you more in the long term, because you may not really need them, or you haven’t shopped around for better deals. Really want something? Take a 24-hour breather and see if you still do.</p> <p><strong>Name brands</strong></p> <p>Brand names can be tempting when it comes to consumer products like cereals and soaps. But the generic versions work just as well. And when it comes to medications, generic versions can cost between 30 and 80 percent less than brand-name drugs. Ask your doctor to specify on the prescription that generic medications should be substituted for name brands.</p> <p><strong>Phantom electricity</strong></p> <p>Everyone wants to make sure their electronic devices are charged. But keeping your laptop and phone plugged in once they’re at full power is costing you – especially with high energy prices. To save money, make sure to power down your devices when you’re not using them and use a power strip to easily turn off several electronics at once.</p> <p><strong>Procrastinating</strong></p> <p>You might think it’s a good idea to wait for last-minute deals, but procrastinating can cost you in the long run. Plane tickets and hotel rooms can get more expensive the closer to the date. And procrastinating on saving money will mean less down the road.</p> <p><strong>Speeding</strong></p> <p>Rushing to get somewhere may be tempting, but it can also add up. On the highway, speeding can decrease your fuel mileage by up to 30 percent. That’s not counting what it will cost you if you get stopped for your leadfoot or hit another vehicle. So slow down and save.</p> <p><strong>Subscription boxes</strong></p> <p>The average subscription box costs between $10 and $40 per month, which means you could be spending well over $100 a year – on just one service. Think about whether you’re really using (and enjoying) the majority of the items in the box on a regular basis. If not, it might be time to cancel your subscription.</p> <p><strong>Unused memberships</strong></p> <p>You signed up for that gym membership with the best of intentions, but if you’re part of the 67 percent of people with a membership who never set foot in the gym, you could be wasting more than $700 a year. And if you’re a member of one of the fancier gyms, you’re wasting even more.</p> <p><strong>Tax deductions you're missing </strong></p> <p>Earned income tax credits were designed to help keep money in people’s pockets. But 20 percent of people who qualify for the deductions don’t take advantage of them. To make sure you get the deductions you’re entitled to, use an online tax program or hire a professional.</p> <p><strong>Wasted food</strong></p> <p>A trip to the grocery store may cost you money in more ways than one. Because of lack of planning, impulse buying, and cooking too much food, an average of one in five bags of groceries goes to waste. To save, make a plan before you go shopping, don’t go to the store hungry, and eat/freeze your leftovers.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/food-home-garden/money/ways-youre-wasting-money-without-knowing-it?pages=1" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Yes, masks reduce the risk of spreading COVID, despite a review saying they don’t

<p>The question of whether and to what extent face masks work to prevent respiratory infections such as COVID and influenza has split the scientific community for <a href="https://www.baltimoresun.com/news/bs-xpm-2007-03-06-0703060040-story.html">decades</a>.</p> <p>Although there is strong evidence face masks <a href="https://www.sciencedirect.com/science/article/pii/S0020748920301139?via%3Dihub">significantly reduce transmission of such infections</a> both in health-care settings and in the community, some experts do not agree.</p> <p>An updated <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD006207.pub6/full">Cochrane Review</a> published last week is the latest to suggest face masks don’t work in the community.</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">"Wearing masks in the community probably makes little or no difference to the outcome of laboratory‐confirmed influenza/SARS‐CoV‐2 compared to not wearing masks"<a href="https://twitter.com/CochraneLibrary?ref_src=twsrc%5Etfw">@CochraneLibrary</a> Review.<br />Published: 30 January 2023 <a href="https://t.co/zODu6QEF1M">https://t.co/zODu6QEF1M</a> <a href="https://t.co/c26yHPaSCD">pic.twitter.com/c26yHPaSCD</a></p> <p>— Robin Monotti (@robinmonotti) <a href="https://twitter.com/robinmonotti/status/1620311528523304960?ref_src=twsrc%5Etfw">January 31, 2023</a></p></blockquote> <p>However there are problems with the review’s methodology and its underpinning assumptions about transmission.</p> <p>The Cochrane Review combined randomised controlled trials (RCTs) using <a href="https://ebn.bmj.com/content/16/1/3">meta-analysis</a>. RTCs test an intervention in one group and compare it with a “control” group that doesn’t receive the intervention or receives a different intervention. A meta-analysis pools the results of multiple studies.</p> <p>This approach assumes (a) RCTs are the “best” evidence and (b) combining results from multiple RCTs will give you an average “effect size”.</p> <p>But RCTs are only the undisputed gold standard for certain kinds of questions. For other questions, a mix of study designs is better. And RCTs should be combined in a meta-analysis only if they are all addressing the same research question in the same way.</p> <p>Here are some reasons why the conclusions of this Cochrane Review are misleading.</p> <h2>It didn’t consider how COVID spreads and how masks work</h2> <p>COVID, along with influenza and many other respiratory diseases, is transmitted primarily <a href="https://theconversation.com/covid-how-the-disease-moves-through-the-air-173490">through the air</a>.</p> <p>Respirators (such as N95s) are designed and regulated to prevent airborne infections by fitting <a href="https://theconversation.com/high-filtration-masks-only-work-when-they-fit-so-we-created-a-new-way-to-test-if-they-do-155987">closely to the face</a> to prevent air leakage and by filtering out 95% or more of potential infectious particles.</p> <p>In contrast, surgical masks are designed to prevent splatter of fluid on the face and are loose-fitting, causing unfiltered air to leak in through the gaps around the mask. The filtration of a surgical mask is not regulated.</p> <p>In other words, respirators are designed for respiratory protection and cloth and surgical masks are not.</p> <p>The review starts with an assumption that masks provide respiratory protection, which is flawed. An understanding of these differences should inform both studies and reviews of those studies.</p> <h2>The studies addressed quite different questions</h2> <p>A common mistake in meta-analysis is to combine apples and oranges. If apples work but oranges don’t, combining all studies in a single average figure may lead to the conclusion that apples do not work.</p> <p>This Cochrane Review combined RCTs where face masks or respirators were worn part of the time (for example, when caring for patients with known COVID or influenza: “occasional” or “targeted” use) with RCTs where they were worn at all times (“continuous use”).</p> <p>Because both SARS-CoV-2 and influenza viruses are airborne, an unmasked person could be infected anywhere in the building and even after an infectious patient has left the room, especially since some people have <a href="https://www.pnas.org/doi/10.1073/pnas.2109229118">no symptoms</a> while contagious.</p> <p>Most RCTs of masks and N95s included in the review have not had a <a href="https://jamanetwork.com/journals/jama/fullarticle/184819">control arm</a> – therefore finding no difference could indicate equal efficacy or equal inefficacy.</p> <p><a href="https://jamanetwork.com/journals/jama/fullarticle/2749214">Studies</a> examining wearing a surgical mask or respirator (such as an N95) only when in contact with sick people or when doing a high-risk procedure (occasional use) have generally shown that, when worn in this way, there is no difference.</p> <p>An RCT comparing occasional versus continuous use of respirators in health care workers <a href="https://www.atsjournals.org/doi/10.1164/rccm.201207-1164OC?url_ver=Z39.88-2003&amp;rfr_id=ori:rid:crossref.org&amp;rfr_dat=cr_pub%20%200pubme">showed</a> N95 respirators and surgical masks were equally ineffective when only worn occasionally by hospital workers. They had to wear them all the time at work to be protected.</p> <p>We also combined only apples and apples in a <a href="https://onlinelibrary.wiley.com/doi/10.1111/irv.12474">meta-analysis</a> of two RCTs conducted in exactly the same way and measuring the same interventions and outcomes. We found N95 respirators provide significant protection against respiratory infections when surgical masks did not, even against infections assumed to be “droplet spread”.</p> <h2>Most trials addressed only half the question</h2> <p>Face masks and respirators work in two ways: they protect the wearer from becoming infected and they prevent an infected wearer from spreading their germs to other people.</p> <p>Most RCTs in this Cochrane Review looked only at the former scenario, not the latter. In other words, the researchers had asked people to wear masks and then tested to see if those people became infected.</p> <p>A previous <a href="https://pubmed.ncbi.nlm.nih.gov/20092668/">systematic review</a> found face masks worn by sick people during an influenza epidemic reduced the risk of them transmitting the infection to family members or other carers. Preventing an infection in one person also prevents onward transmission to others within a closed setting, which means such RCTs should use a special method called “cluster randomisation” to account for this.</p> <p>Data from a RCT of N95 respirator use by <a href="https://journals.sagepub.com/doi/full/10.1177/0300060516665491?rfr_dat=cr_pub++0pubmed&amp;url_ver=Z39.88-2003&amp;rfr_id=ori%3Arid%3Acrossref.org">health workers</a> showed even their unmasked colleagues were protected. Yet some of the trials included in the review did not use cluster randomisation.</p> <h2>The new paper combined health and community settings</h2> <p>This is another apples-plus-oranges issue. Different settings have widely differing risks of transmission, since airborne particles build up when sick patients are exhaling the virus in <a href="https://theconversation.com/heres-where-and-how-you-are-most-likely-to-catch-covid-new-study-174473">underventilated, crowded settings</a> especially if many infected people are present (such as in a hospital).</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">Here’s where (and how) you are most likely to catch COVID – new study <a href="https://t.co/Ro88Shc897">https://t.co/Ro88Shc897</a> <a href="https://t.co/TlFA9EQskF">pic.twitter.com/TlFA9EQskF</a></p> <p>— Jeffrey J Davis (@JeffreyJDavis) <a href="https://twitter.com/JeffreyJDavis/status/1484210379093954564?ref_src=twsrc%5Etfw">January 20, 2022</a></p></blockquote> <p>A genuine protective effect of masks or respirators shown in a RCT in a high-risk setting will be obscured if that trial is combined in a meta-analysis with several other RCTs that were conducted in low-risk settings.</p> <p>A large <a href="https://www.science.org/doi/10.1126/science.abi9069">RCT in the community in Bangladesh</a> found face masks reduced the risk of infection by 11% overall and 35% in people over 60 years. In contrast, in <a href="https://onlinelibrary.wiley.com/doi/10.1111/irv.12474">hospitals</a>, N95 reduce risk by 67% against bacterial infections and 54% against viral infections.</p> <p>Viruses like influenza also vary substantially from year to year – some years there is very little influenza, and if a RCT is conducted during such a year, it will not find enough infections to show a difference. The review failed to account for such seasonal effects.</p> <h2>But did they actually wear the mask?</h2> <p>The authors of the Cochrane Review acknowledged compliance with masking advice was poor in most studies. In the real world, we can’t force people to follow medical advice, so RCTs should be analysed on an “intention to treat” basis.</p> <p>For example, people who are prescribed the active drug but who choose not to take it should not be shifted to the placebo group for the analysis. But if in a study of masking, most people don’t actually wear them, you can’t conclude that masks don’t work when the study shows no difference between the groups. You can only conclude that the mask advice didn’t work in this study.</p> <p>There is a great deal of <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0246317">psychological evidence</a> on why people do or don’t choose to comply with advice to mask and how to improve uptake. The science of masking needs to separate the impact of the mask itself from the impact of the advice to mask.</p> <p>Mask-wearing <a href="https://www.ijidonline.com/article/S1201-9712(21)00274-5/fulltext">goes up</a> substantially to over 70% if there is an actual mandate in place.</p> <h2>It didn’t include other types of research</h2> <p>A comprehensive review of the evidence would also include other types of study besides RCTs. For example, a <a href="https://www.sciencedirect.com/science/article/pii/S0140673620311429">large systematic review</a> of 172 various study designs, which included 25,697 patients with SARS-CoV-2, SARS, or MERS, concluded masks were effective in preventing transmission of respiratory viruses.</p> <p>Well-designed <a href="https://www.cdc.gov/mmwr/volumes/71/wr/mm7106e1.htm?s_cid=mm7106e1_w">real-world studies</a> during the pandemic showed any mask reduces the risk of COVID transmission by 50–80%, with the highest protection offered by N95 respirators.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/20095070/">Many lab-based studies</a> have shown respirators are superior to masks at preventing airborne respiratory infections and the <a href="https://thorax.bmj.com/content/75/11/1024.long">incremental superiority</a> from a single to two layered cloth mask to a three-layered surgical mask in blocking respiratory aerosols.</p> <h2>Yes, masks reduce the spread of COVID</h2> <p>There is strong and consistent evidence for the effectiveness of masks and (even more so) respirators in protecting against respiratory infections. Masks are an important protection against serious infections.</p> <p>Current COVID vaccines protect against death and hospitalisation, but do <a href="https://fortune.com/well/2023/01/06/kraken-xbb15-omicron-covid-variant-most-transmissible-yet-could-spawn-more-immune-evasive-variants-study-china-vaccine-monoclonal-antibodies-breakthrough-infection/">not prevent infection</a> well due to waning vaccine immunity and substantial immune escape from new variants.</p> <p>A systematic review is only as good as the rigour it employs in combining similar studies of similar interventions, with similar measurement of outcomes. When very different studies of different interventions are combined, the results are not informative.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/yes-masks-reduce-the-risk-of-spreading-covid-despite-a-review-saying-they-dont-198992" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Toxic pollutants can build up inside our homes. Here are 8 ways to reduce the risks

<p>We know everything in our homes gathers dust. What you probably don’t know is whether there are toxic contaminants in your house dust, and where these might come from. </p> <p>Our <a href="https://doi.org/10.1016/j.envres.2022.115173">newly published research</a> found most of the dust inside homes came from outside and contains potentially toxic trace metals such as lead, arsenic and chromium. </p> <p>Worryingly, we found some contaminants can accumulate at higher concentrations inside homes than outside. This happened in homes with certain characteristics: older properties, metal construction materials enriched in zinc, recent renovations and deteriorating paint. </p> <p>Fortunately, you can take some simple steps to reduce your exposure, which we explain later.</p> <h2>What’s in house dust?</h2> <p>Our study explored the connected sources, pathways and potentially harmful exposures to trace metals at homes across Sydney. We collected and analysed 383 samples from nearby road dust (51 samples) and garden soil (166), as well as indoor dust (166).</p> <p>We found the dust in homes comes from a range of sources including outdoor environments and soil, skin, cleaning products, pet hair and cooking particles.<br />Nearly 60% of dust particles inside the homes originated from their immediate outdoor environment – it was <a href="https://theconversation.com/wearing-shoes-in-the-house-is-just-plain-gross-the-verdict-from-scientists-who-study-indoor-contaminants-177542">dirt from outside</a>! Wind, your shoes or your pets can carry in <a href="https://www.sciencedirect.com/science/article/pii/S0160412021002075?via%3Dihub">soil</a> and <a href="https://pubs.acs.org/doi/10.1021/acs.est.1c04494">dust</a>-related contaminants.</p> <p>The remaining 40% of home dust came from indoor sources. These included <a href="https://theconversation.com/microplastics-are-common-in-homes-across-29-countries-new-research-shows-whos-most-at-risk-189051">fibres from clothes, carpets and furnishings</a>, cleaning products, skin and hair.</p> <p>Some dust sources can carry a cocktail of potentially harmful contaminants including:</p> <ul> <li> <p><a href="https://doi.org/10.1016/j.envpol.2021.117064">microplastics</a></p> </li> <li> <p><a href="https://doi.org/10.1016/j.envres.2014.10.009">persistent organic pollutants</a></p> </li> <li> <p><a href="https://doi.org/10.1016/j.scitotenv.2019.05.463">perfluorinated chemicals</a> (PFAS)</p> </li> <li> <p><a href="https://doi.org/10.1016/j.envpol.2021.117593">trace metals</a></p> </li> <li> <p><a href="https://doi.org/10.3389/fenvs.2021.754657">bacterial communities</a></p> </li> <li> <p><a href="https://doi.org/10.1016/j.envint.2021.106501">antimicrobial resistance genes</a>. </p> </li> </ul> <p>The nature of the risk is related to how much of the contaminant you’re exposed to and for how long. The risks are greatest in children under the age of five. This is because they are small, closer to the floor and have frequent hand-mouth contact, which increases ingestion of contaminants.</p> <h2>How do contaminants build up in homes?</h2> <p>Industrial activity has left a marked legacy of contaminants in many city neighbourhoods. We analysed road dust, garden soil and vacuum dust samples from 166 homes in Sydney to see how this risk translated to inside homes. We used high-magnification microscopy and <a href="https://www.climate-policy-watcher.org/earth-sciences/lead-isotopes-as-tools-for-source-identification.html">lead isotopic ratios</a> to understand trace metal composition in the samples. </p> <p>On average, concentrations of trace metals arsenic, chromium, copper, manganese, lead and zinc were all higher inside homes than outside. This means homes are not only “accumulators” of trace metal contaminants but also important sources of a significant proportion of harmful contaminants that we can be exposed to. </p> <p>The lead isotopic ratios, or the lead “fingerprints”, of each home and its garden soil matched.
