Why scalp care is just important as washing your hair

<p dir="ltr">When it comes to our daily beauty routines, we tend to focus on what looks and feels like it needs a refresh, such as washing our hair when it looks a little greasy, or cleansing our faces after a day of wearing makeup. </p> <p dir="ltr">While our beauty, skin and hair care routines are quick to become second nature, there is one area that often gets overlooked: our scalps. </p> <p dir="ltr">When washing our hair, it is easy to focus on the products and techniques we need to get our tresses clean, while skimping on what is best for our scalp. </p> <p dir="ltr">But now, the scalp, which is often the most overlooked part of our skin, is finally being recognised as an area that needs just as much TLC as your face.</p> <p dir="ltr">Implementing scalp care as part of our beauty routines is a must, as this sensitive area can often need extra attention due to a build-up of product, delicate skin and aggressive hair washing techniques. </p> <p dir="ltr">Hair care expert Sanja Scher from Beatnik Studio has shared how important it is to care for the scalp as the foundation for hair growth and health, and how it all starts with the right products. </p> <p dir="ltr">"Revlon Professional, known for game-changing professional haircare, styling, and colour, offers a range of products dedicated to improving the scalp - and they're available to take home. By removing excess build-up, replenishing moisture, and rebalancing the scalp’s microbiome, these targeted products ensure that the microbiome, the first line of defence, can shield hair follicles from pathogens, hair damage, infections and other irritations,” she said.  </p> <p dir="ltr">“And this equals healthier, stronger, more beautiful hair.”</p> <p dir="ltr">To kick start the revolution of your hair care routine to protect your scalp, Revlon Professional's launch of the Eksperience Marine Face Mist Ultra-Light Hydration is a game-changing product that effortlessly combines skin care with hair care.</p> <blockquote class="instagram-media" style="background: #FFF;

Why and how often do I need to wash makeup brushes and sponges?

<p><em><a href="https://theconversation.com/profiles/enzo-palombo-249510">Enzo Palombo</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> and <a href="https://theconversation.com/profiles/rosalie-hocking-1428271">Rosalie Hocking</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>From the bristles of brushes to the porous surfaces of sponges, your makeup kit can harbour a host of bacteria and fungi.</p> <p>These potentially hazardous contaminants can originate not only from the cosmetics themselves, but also from the very surface of our skin.</p> <p>So, how can we keep things hygienic and avoid microbial growth on makeup brushes and sponges? Here’s what you need to know.</p> <h2>How do germs and fungi get in my brushes and sponges?</h2> <p>Germs and fungi can make their way into your makeup kit in lots of ways.</p> <p>Ever flushed a toilet with the lid open with your makeup brushes nearby? There’s a good chance <a href="https://theconversation.com/mobile-phones-are-covered-in-germs-disinfecting-them-daily-could-help-stop-diseases-spreading-135318">faecal particles</a> have landed on them.</p> <p>Perhaps a family member or housemate has used your eyeshadow brush when you weren’t looking, and transferred some microbes across in the process.</p> <p>Bacteria that trigger a pimple outbreak can be easily transferred from the surface of your skin to a makeup brush or sponge.</p> <p>And tiny little mites called Demodex mites, which have been linked to certain rashes and acne, live on your skin, as well, and so may end up in your sponge or brushes.</p> <p>Bacterial contamination of <a href="https://pubmed.ncbi.nlm.nih.gov/38020232/">lip cosmetics</a>, in particular, can pose a risk of skin and eye infections (so keep that in mind if you use lip brushes). Lipsticks are frequently contaminated with bacteria such as <em>Staphylococcus aureus</em>, <em>E. coli</em>, and <em>Streptococcus pneumoniae</em>.</p> <p>Low-quality cosmetics are more likely to have higher and more diverse microbial growth compared to <a href="https://www.sciencedirect.com/science/article/pii/S1319562X23002978?pes=vor">high-quality cosmetics</a>.</p> <p>Brushes exposed to sensitive areas like the eyes, mouth and nose are particularly susceptible to being potential sources of infection.</p> <p>The range of conditions caused by these microorganisms includes:</p> <ul> <li> <p>abscesses</p> </li> <li> <p>skin and soft tissue infections</p> </li> <li> <p>skin lesions</p> </li> <li> <p>rashes</p> </li> <li> <p>and dermatitis.</p> </li> </ul> <p>In severe cases, infections can lead to invasion of the bloodstream or deep tissues.</p> <p>Commercially available cosmetics contain varying amounts and types of preservatives aimed at inhibiting the growth of fungi and bacteria.</p> <p>But when you apply makeup, different cosmetics with unique formulations of preservatives can become mixed. When a preservative meant for one product mixes with others, it might not work as well because they have different water amounts or pH levels.</p> <p>So preservatives are not foolproof. We also need to observe good hygiene practices when it comes to brushes and other cosmetics applicators.</p> <h2>Keeping brushes clean</h2> <p>Start with the basics: never <a href="https://www.semanticscholar.org/paper/Isolation-of-Pathogenic-Microbes-from-Beauty-Salons-Hassan-Hamad/0199635290628fe326fcd04a2b8a2422884a8240">share makeup brushes or sponges</a>. Everyone carries different microbes on their skin, so sharing brushes and sponges means you are also sharing germs and fungi.</p> <p>If you need to share makeup, use something disposable to apply it, or make sure any shared brushes are washed and sterilised before the next person uses it.</p> <p>Clean makeup brushes by washing with hot soapy water and rinsing thoroughly.</p> <p>How often? Stick to a cleaning routine you can repeat with consistency (as opposed to a deep clean that is done annually). <a href="https://www.aad.org/public/everyday-care/skin-care-secrets/routine/clean-your-makeup-brushes#:%7E:text=To%20protect%20your%20skin%20and,every%207%20to%2010%20days.">Once a week</a> might be a good goal for some, while others may need to wash more regularly if they are heavy users of makeup.</p> <p>Definitely wash straight away if someone else has used your brushes or sponges. And if you’ve had an eye infection such as conjunctivitis, ensure you clean applicators thoroughly after the infection has resolved.</p> <p>You can use bactericidal soap, 70% ethanol or chlorhexidine solutions to wash. Just make sure you wash very thoroughly with hot water after, as some of these things can irritate your skin. (While some people online say alcohol can degrade brushes and sponges, opinion seems to be mixed; in general, most disinfectants are unlikely to cause significant corrosion.)</p> <p>For some brushes, heating or steaming them and letting them dry may also be an effective sterilisation method once they are washed with detergent. Microwaving sponges isn’t a good idea because while the heat generated by a domestic microwave would kill microbes, it would need temperatures approaching 100°C for a decent period of time (at least several minutes). The heat could melt some parts of the sponge and hot materials could be a scalding hazard.</p> <p>Once clean, ensure brushes and sponges are stored in a dry place away from water sources (and not near an open toilet).</p> <p>If you’re having makeup applied professionally, brushes and applicators should be sterilised or changed from person to person.</p> <h2>Should I wash them with micellar water?</h2> <p>No.</p> <p>Not only is this expensive, it’s unnecessary. The same benefits can be achieved with cheaper detergents or alcohol (just rinse brushes carefully afterwards).</p> <p>Disinfection methods such as using bactericidal soap, 70% ethanol, or chlorhexidine are all very good at reducing the amount of microbes on your brushes and sponges.<!-- Below is The Conversation's page counter tag.

Spin cycle disaster: man puts winning Lotto ticket through the wash

<p>In a harrowing tale that's sure to wring out a chuckle or two, a man in his late 20s from <span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">Belmont, Western Australia, </span><span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">narrowly escaped laundering his way out of a $2.8 million windfall – after nearly sacrificing his winning lottery ticket to the treacherous depths of his washing machine.</span></p> <p>It all started innocently enough at the Here's Luck Lottery Centre in Belmont Forum, where our hero – who very sensibly prefers to remain incognito – purchased what would turn out to be a life-changing ticket for the Saturday Lotto. Little did he know, his unassuming trousers would soon become the epicentre of a near-catastrophe.</p> <p>In a classic case of absentmindedness, our hero forgot to take his ticket out of his pants pocket before succumbing to the siren song of laundry day.</p> <p>"I forgot to take the ticket out of my trousers and put it in the washing machine," confessed the forgetful winner. "After five minutes I realised and stopped the washing machine to grab the ticket, fortunately, it was safe."</p> <p>Indeed, it was a race against the spin cycle as the man scrambled to rescue his potential fortune from a soapy demise. "I couldn’t think, I couldn’t sleep, I am still processing the win," he admitted with palpable relief.</p> <p>But our protagonist emerged victorious from this sudsy saga, managing to salvage his ticket just in the nick of time. With a sigh of relief, he made his way to Lotterywest HQ to claim his well-deserved prize.</p> <p>Lotterywest spokesman James Mooney chimed in, highlighting the importance of registering tickets to avoid potential mishaps of this magnitude. "For this player, it all came out of the wash okay, but it’s a reminder for players to register their ticket to prevent what could be a multimillion-dollar mistake," he wisely advised.</p> <p><em>Image: Getty</em></p>

How often should you wash your sheets and towels?

<p><em><a href="https://theconversation.com/profiles/rietie-venter-100529">Rietie Venter</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>Everyone seems to have a different opinion when it comes to how often towels and <a href="https://7news.com.au/video/lifestyle/cleaning/dr-karl-on-how-often-you-should-wash-our-sheets-bc-6320410318112">bed sheets should be washed</a>. While many people might wonder whether days or weeks is best, in one survey from the United Kingdom, <a href="https://www.bbc.com/news/newsbeat-61259074">almost half of single men</a> reported not washing their sheets for up to four months at a time.</p> <p>It’s fairly clear that four months is too long to leave it, but what is the ideal frequency?</p> <p>Bed linen and towels are quite different and so should be washed at different intervals. While every week or two will generally suffice for sheets, towels are best washed every few days.</p> <p>Anyway, who doesn’t love the feeling of a fresh set of sheets or the smell of a newly laundered towel?</p> <h2>Why you should wash towels more often</h2> <p>When you dry yourself, you deposit thousands of <a href="https://www.frontiersin.org/articles/10.3389/fmicb.2018.02362/full">skin cells</a> and millions of <a href="https://www.ajicjournal.org/article/S0196-6553(23)00402-9/fulltext">microbes</a> onto the towel. And because you use your towel to dry yourself after a shower or bath, your towel is regularly damp.</p> <p>You also deposit a hefty amount of dead skin, microbes, sweat and oils <a href="https://theconversation.com/your-bed-probably-isnt-as-clean-as-you-think-a-microbiologist-explains-163513">onto your sheets</a> every night. But unless you’re a prolific night sweater, your bedding doesn’t get wet after a night’s sleep.</p> <p>Towels are also made of a thicker material than sheets and therefore tend to stay damp for longer.</p> <p>So what is it about the dampness that causes a problem? Wet towels are a breeding ground for bacteria and moulds. <a href="https://www.qld.gov.au/housing/public-community-housing/public-housing-tenants/looking-after-your-home/safety/mould">Moulds</a> especially love <a href="https://www.asthmaandlung.org.uk/living-with/indoor-air-pollution/allergies">damp environments</a>. Although mould won’t necessarily be visible (you would need significant growth to be able to see it) this can lead to an unpleasant smell.</p> <p>As well as odours, <a href="https://www.nhs.uk/common-health-questions/infections/can-clothes-and-towels-spread-germs/">exposure to these microbes</a> in your towels and sheets can cause <a href="https://aafa.org/allergies/types-of-allergies/insect-allergy/dust-mite-allergy/">asthma</a>, allergic skin irritations, or other <a href="https://wwwnc.cdc.gov/eid/article/11/4/04-1094_article">skin infections</a>.</p> <h2>So what’s the ideal frequency?</h2> <p>For bedding, it really depends on factors such as whether you have a bath or shower just before going to bed, or if you fall into bed after a long, sweaty day and have your shower in the morning. You will need to wash your sheets more regularly in the latter case. As a rule of thumb, once a week or every two weeks should be fine.</p> <p>Towels should ideally be washed more regularly – perhaps every few days – while your facecloth should be cleaned after every use. Because it gets completely wet, it will be wet for a longer time, and retain more skin cells and microbes.</p> <p>Wash your towels at a high temperature (for example, 65°C) as that will <a href="https://pubmed.ncbi.nlm.nih.gov/34465009/">kill many microbes</a>. If you are conscious of saving energy, you can use a lower temperature and add a cup of vinegar to the wash. The vinegar will kill microbes and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8231443/">prevent bad smells</a> from developing.</p> <p>Clean your washing machine regularly and dry the fold in the rubber after every wash, as this is another place microbes like to grow.</p> <h2>Smelly towels</h2> <p>What if you regularly wash your towels, but they still smell bad? One of the reasons for this pong could be that you’ve left them in the washing machine too long after the wash. Especially if it was a warm wash cycle, the time they’re warm and damp will allow microbes to happily grow. Under <a href="https://textbookofbacteriology.net/growth_3.html">lab conditions</a> the number of these bacteria can double every 30 minutes.</p> <p>It’s important to hang your towel out to dry after use and not to leave towels in the washing machine after the cycle has finished. If possible, hang your towels and bedding out in the sun. That will dry them quickly and thoroughly and will foster that lovely fresh, clean cotton smell. Using a dryer is a good alternative if the weather is bad, but outdoors in the sun is always better if possible.</p> <p>Also, even if your towel is going to be washed, don’t throw a wet towel into the laundry basket, as the damp, dirty towel will be an ideal place for microbes to breed. By the time you get to doing your washing, the towel and the other laundry around it may have acquired a bad smell. And it can be difficult to get your towels smelling fresh again.</p> <h2>What about ‘self-cleaning’ sheets and towels?</h2> <p>Some companies sell “quick-dry” towels or “self-cleaning” towels and bedding. Quick-dry towels are made from synthetic materials that are weaved in a way to allow them to dry quickly. This would help prevent the growth of microbes and the bad smells that develop when towels are damp for long periods of time.</p> <p>But the notion of self-cleaning products is more complicated. Most of these products contain <a href="https://www.degruyter.com/document/doi/10.1515/chem-2016-0005/html">nanosilver</a> or copper, antibacterial metals that kill micro-organisms. The antibacterial compounds will stop the growth of bacteria and can be useful to limit smells and reduce the frequency with which you need to clean your sheets and towels.</p> <p>However, they’re not going to remove dirt like oils, skin flakes and sweat. So as much as I would love the idea of sheets and towels that clean themselves, that’s not exactly what happens.</p> <p>Also, excessive use of antimicrobials <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6636436/pdf/idr-12-1985.pdf">such as nanosilver</a> can lead to <a href="https://www.frontiersin.org/articles/10.3389/fmicb.2021.652863/full">microbes becoming resistant</a> to them.<!-- Below is The Conversation's page counter tag.

Treadmill, exercise bike, rowing machine: what’s the best option for cardio at home?

<p><em><a href="https://theconversation.com/profiles/lewis-ingram-1427671">Lewis Ingram</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a>; <a href="https://theconversation.com/profiles/hunter-bennett-1053061">Hunter Bennett</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a>, and <a href="https://theconversation.com/profiles/saravana-kumar-181105">Saravana Kumar</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>Cardio, short for cardiovascular exercise, refers to any form of rhythmic physical activity that increases your heart rate and breathing so the heart and lungs can deliver oxygen to the working muscles. Essentially, it’s the type of exercise that gets you huffing and puffing – and fills many people with dread.</p> <p>People often do cardio to <a href="https://pubmed.ncbi.nlm.nih.gov/30003901/">lose weight</a>, but it’s associated with a variety of health benefits including reducing the risk of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6481017/">heart disease</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/30191075/">stroke</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/27707740/">falls</a>. Research shows cardio also improves <a href="https://pubmed.ncbi.nlm.nih.gov/29334638/">cognitive function</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/26978184/">mental health</a>.</p> <p>The <a href="https://www.who.int/news-room/fact-sheets/detail/physical-activity">World Health Organization</a> recommends a minimum of 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity cardio per week.</p> <p>There are many ways to do cardio, from playing a team sport, to riding your bike to work, to going for a jog. If you’re willing and able to invest in a piece of equipment, you can also do cardio at home.</p> <p>The treadmill, stationary bike and rowing machine are the most popular pieces of cardio equipment you’ll find in a typical gym, and you can buy any of these for your home too. Here’s how to know which one is best for you.</p> <h2>The treadmill</h2> <p>In terms of effectiveness of exercise, it’s hard to look past the treadmill. Running uses most of your major muscle groups and therefore leads to greater increases in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1334197/">heart rate</a> and energy expenditure compared to other activities, such as cycling.</p> <p>As a bonus, since running on a treadmill requires you to support your own body weight, it also helps to build and maintain <a href="https://pubmed.ncbi.nlm.nih.gov/26562001/">your bones</a>, keeping them strong. This becomes even more important <a href="https://www.niams.nih.gov/health-topics/exercise-your-bone-health">as you get older</a> as the risk of developing medical conditions such as osteopenia and osteoporosis – where the density of your bones is reduced – increases.</p> <p>But the treadmill may not be for everyone. The weight-bearing nature of running may exacerbate pain and cause swelling in people with common joint conditions such as osteoarthritis.</p> <p>Also, a treadmill is likely to require greater maintenance (since most treadmills are motorised), and can take up a lot of space.</p> <h2>Stationary bike</h2> <p>The stationary bike provides another convenient means to hit your cardio goals. Setting the bike up correctly is crucial to ensure you are comfortable and to reduce the risk of injury. A general rule of thumb is that you want a slight bend in your knee, as in the picture below, when your leg is at the bottom of the pedal stroke.</p> <p>While cycling has significant benefits for <a href="https://pubmed.ncbi.nlm.nih.gov/21496106/">cardiovascular</a> and metabolic health, since it’s non-weight-bearing it doesn’t benefit your <a href="https://www.sciencedirect.com/science/article/pii/S0026049507003253">bones</a> to the same extent as walking and running. On the flipside, it offers a great cardio workout without stressing your joints.</p> <h2>Rowing machine</h2> <p>If you’re looking to the get the best cardio workout in the least amount of time, the rowing machine might be for you. Because rowing requires you to use all of your major muscle groups including the upper body, your heart and lungs have to work even harder than they do when <a href="https://pubmed.ncbi.nlm.nih.gov/32627051/">running and cycling</a> to <a href="https://pubmed.ncbi.nlm.nih.gov/8325720/">deliver oxygen</a> to those working muscles. This means the energy expended while rowing is comparable to running and <a href="https://pubmed.ncbi.nlm.nih.gov/3193864/">greater than cycling</a>.</p> <p>But before you rush off to buy a new rower, there are two issues to consider. First, the technical challenge of rowing is arguably greater than that of running or cycling, as the skill of rowing is often less familiar to the average person. While a coach or trainer can help with this, just remember a good rowing technique should be felt primarily in your legs, not your arms and back.</p> <p>Second, the non-weight-bearing nature of rowing means it misses out on the same bone health benefits offered by the treadmill – although there is some evidence it still can increase bone density <a href="https://pubmed.ncbi.nlm.nih.gov/7551766/">to a smaller degree</a>. Nevertheless, like cycling, this drawback of rowing may be negated by offering a more joint-friendly option, providing a great alternative for those with joint pain who still want to keep their heart and lungs healthy.</p> <h2>So, what’s the best option?</h2> <p>It depends on your goals, what your current health status is, and, most importantly, what you enjoy the most. The best exercise is the one that gets done. So, choose whichever piece of equipment you find the most enjoyable, as this will increase the likelihood you’ll stick to it in the long term.<!-- Below is The Conversation's page counter tag.

"Coca coila": Robert Irwin rescues a python stuck in a vending machine

<p>Robert Irwin has successfully rescued a carpet python stuck a vending machine at Australia Zoo. </p> <p>The young conservationist took to Instagram to share the moment he rescued the snake with the caption: "So this was a first for me…"</p> <p>The carpet python was visibly stuck behind a few soft drink bottles, and as the vending machine was being opened, the 19-year-old joked, "here's our chance, free Coca Cola!"</p> <p>He then got down to business, trying to coax the snake out while explaining, "what we don't want is for him to go up into the wiring.</p> <p>"We don't want to make him too upset, 'cause we want him to come out nice and smooth," he added as he pulled the snake out of the vending machine. </p> <p>The young conservationist sounded exactly like his late father, Steve Irwin, as he tried to calm down the non-venomous snake. </p> <p>"Keep coming, mate, keep coming. Nearly there buddy, nearly there," he said. </p> <p>As he examined the snake, he pointed out that the snake must have gotten injured before. </p> <p>"This bloke has obviously got a spirit of getting himself caught in weird situations, 'cause he's missing the end of his tail. </p> <p>"We'll relocate this guy," he assured, as the snake wrapped around his arm, Robert wags a finger at him and jokingly says: "don't go in any more vending machines, alright?!"</p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/reel/Cw7cZl4hX4C/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/Cw7cZl4hX4C/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Robert Irwin (@robertirwinphotography)</a></p> </div> </blockquote> <p>Fans were in awe at Robert's striking resemblance to his late dad, and praised him for skills. </p> <p>"God you are the spitting image of the old man.

Mystery object washed up on WA beach finally identified

<p>Ok space enthusiasts and beachcombers. Here's one for the X-Files – Intergalactic Travel edition.</p> <p>Picture this: A strange and baffling object, looking like it's straight out of a sci-fi flick, decided to take a little trip to Green Head beach, about 250 kilometres north of Perth on the pristine WA coastline.</p> <p>As soon as the locals caught sight of this extraterrestrial-looking thingamajig, the news spread like wildfire, and it made international headlines faster than a speeding rocket, with all kinds of fascinating theories popping up as to what on <em>Earth</em> (or not on Earth) it could be.</p> <p>Was it a UFO? A top-secret government experiment gone awry? Well, turns out it was nothing that exciting. The Australian Space Agency put on their Sherlock Holmes hats and deduced that this enigmatic piece of debris probably came from a satellite launch vehicle. Eureka! Case closed!</p> <p>Of course, when something weird and otherworldly shows up on your doorstep, you can't be too careful. So, the local authorities played it safe and put the object under police guard for an entire week. (Better safe than sorry, right?)</p> <p>And who needs a red carpet when you have a front-end loader to transport your newfound cosmic artifact? The experts were summoned to figure out where this space junk came from, and they concluded it was most likely a fuel tank from some rocket launched by the Indian Space Research Organisation. </p> <p>Professor Alice Gorman from Flinders University explained to <a href="https://www.abc.net.au/news/2023-07-31/australian-space-agency-identifies-space-junk-green-head/102669472" target="_blank" rel="noopener">ABC News</a> that this fuel containment vessel was meant to fall off after launch. And it turns out that statistically, we've been pretty lucky not to have had more collisions with falling rocket parts. Imagine explaining that to your insurance company? "A rocket booster landed on my house. Is that covered?"</p> <p>But here comes the tricky part: What to do with all of this space garbage? Should they ship it back to India like some interstellar postcard, or leave it Down Under as an intergalactic souvenir?</p> <p>While India is technically (and legally) responsible for their space debris, they could decide to gift it to Australia if they so choose. It could be like an exotic space decoration for the country - "The Land of Kangaroos and Rocket Wreckage."</p> <p>Even better, the Green Head community itself appear to have come up with a few fabulous ideas. Forget the Sydney Opera House: let's make the space debris a tourist attraction! Move over, Eiffel Tower - we've got our own piece of space history right here.</p> <p>The WA Premier even suggested storing it next to space debris from NASA's Skylab space station (remember that?) in some kind of attempt to build a cosmic cabinet of curiosities. </p> <p>Of course, the local council is also very keen on keeping this celestial treasure. They're hoping the Indian government won't come back to claim it, to the point that everyone in the surrounding Shire of Coorow is buzzing with excitement over the possibility of having their very own space souvenir to draw crowds of star trekkers.</p> <p>And so while the mystery of the object on the beach has been solved, the debate over its fate is just beginning. Will it become a star attraction in a local park? Or will it be shipped off to India like an interplanetary package return? Only time will tell.</p> <p><em>Images: Nine News</em></p>

5 things we all do wrong in the shower

<p>While showering every day keeps us smelling fresh, it actually disturbs the natural bacteria on our skin and strips it of the oils that keep it supple. In fact, many shower habits can actually be very unhygienic. Experts reveal what we’re doing wrong, and what to do instead.</p> <p><strong>1.  Showering everyday </strong></p> <p>The University of California found that too much washing can actually be bad for you, because it strips away beneficial bugs that the body uses to help ward off infections. Apparently, if we simply wash our hands and below the belt regularly we can skip a full shower every day.</p> <p><strong>2.  Showering for too long </strong></p> <p>Water is an irritant, so the longer you’re in there, the more irritated and dry your skin will become. Oil from the sebaceous glands hydrate the skin, so showering for too long strips it of moisture.</p> <p><strong>3. Rubbing soap on your whole body</strong></p> <p>Soap dislodges dirt and oil from the body, allowing water to wash it away. But the skin on the arms and legs doesn't contain a lot of oil, so cleaning them with soap just makes them dry.  Instead, simply focus on the armpits, buttocks, groin and feet</p> <p><strong>4.  Letting the shower water blast over your face </strong></p> <p>A hot shower can cause and exacerbate fragile capillary networks in the cheeks, leading to unattractive, visible capillary networks and worsened impaired skin conditions, experts warn.</p> <p><strong>5.  Using a pouf </strong></p> <p>Poufs and loofahs are a haven for bacteria — the dead skin cells they scrub so well from our body get caught up in the nooks where bacteria can feed on them. Also, because poufs take time to dry and may well retain dead skin cells, it’s a potential source of infection. To keep it clean, wet your pouf and put it on a medium heat in the microwave for 30 to 60 seconds.</p> <p>How would you feel about skipping your daily shower, like one of these tips suggests? Let us now in the comments below.</p> <p><em>Image credit: Shutterstock</em></p> <p><strong>Related links:</strong></p> <p><span style="text-decoration: underline;"><strong><a href="../health/body/2016/03/ways-to-stay-active-in-winter/"><em>4 ways to stay active in winter</em></a></strong></span></p> <p><span style="text-decoration: underline;"><strong><a href="../health/body/2016/04/ways-weather-influences-your-health-and-behaviour/"><em>5 ways weather influences your health and behaviour</em></a></strong></span></p> <p><span style="text-decoration: underline;"><strong><a href="../%20http:/www.oversixty.com.au/lifestyle/home-garden/2016/04/how-to-get-the-best-lawn-for-winter/"><em>How to get the best lawn for winter</em></a></strong></span></p>

8 hair washing tips to transform your tresses this winter

<p dir="ltr">One curly-haired influencer has shared her secrets to happy and healthy hair with the world, promising small changes that “make a big impact” over all. </p> <p dir="ltr">In a video posted to her social media accounts, Jennie - who goes by ‘The Curly Carr’ online - stressed the importance of learning to properly cleanse hair, and the benefits it can have on the likes of “hair health, definition, shine, volume, and growth”.</p> <p dir="ltr">As she explained, she too used to be guilty of just hopping in the shower, quickly slathering her hair in shampoo, and rinsing to get the job done. </p> <p dir="ltr">“I had no clue what I was doing!” she confessed. “Seems like such a small thing, but makes a big impact.”</p> <p dir="ltr">But luckily for Jennie - and anyone else fortunate enough to hear her top tips - she did learn what she should be doing, working her way towards the luscious locks many dream of, before setting out on her mission to help others on their hair journey.</p> <p dir="ltr">And in just eight simple steps, that won’t cost you a fortune in new products, Jennie has shared her findings, as well as some helpful advice to help with the transition from quickfire wash to thorough and effective hair care. </p> <p dir="ltr">Step one was straightforward enough, with Jennie noting that it’s important to “make sure your hair is thoroughly wet all the way through”. According to some experts, a good wetting with warm water helps hair to open up, allowing for a better conditioning process later on. </p> <p dir="ltr">Step two called for emulsifying shampoo in your hands before it goes anywhere near your head. Essentially, rub it between your hands until it froths up - once you’ve got the suds, it’s time to move on to the hair. </p> <p dir="ltr">Step three instructed hair hopefuls to massage their heads. But, as Jennie advised, do it “with the pads of your fingers, don’t use your nails”. Be gentle up there, just like you would be to your face. </p> <p dir="ltr">Step four followed directly on from three, with the instruction to message “all around your head” and to make sure everything got a good clean. Jennie noted that it may take anywhere from 3-5 minutes, but it would all be worth it to have your scalp cleansed. </p> <p dir="ltr">Step five had Jennie calling for the lengths of hair to be remembered, as “it’s not just your scalp getting buildup with products, dirt, and oil”.</p> <p dir="ltr">Step six was to use a <a href="https://www.priceline.com.au/product/189080/lady-jayne-restorative-scalp-brush-silicon-bristles-1ea">shampoo brush/scalp brush</a>, particularly for those who - like Jennie herself - tended to go a few days between washes, or did a pre-shampoo process. </p> <p dir="ltr">Step seven was another one many would be familiar with, as Jennie noted the importance of making sure all shampoo had been thoroughly washed out “before moving on to conditioner!” </p> <p dir="ltr">And last but not least, step eight instructed viewers to listen to their scalps, as they’d know best when it was time for the next all-important wash. </p> <p dir="ltr">“Your hair can always be refreshed,” Jennie explained, “but if your scalp is dry, itchy, and you can see buildup, it’s time to wash!”</p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/reel/CnmLyOjKDC1/?utm_source=ig_embed&amp;utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/CnmLyOjKDC1/?utm_source=ig_embed&amp;utm_campaign=loading" target="_blank" rel="noopener">A post shared by Jennie 🌷 | Curly Hair Care and Simple Hairstyle Tutorials (@the.curly.carr)</a></p> </div> </blockquote> <p dir="ltr"><em>Images: TikTok</em></p>

No, you shouldn’t wash raw chicken before cooking it. So why do people still do it?

<p>Food safety authorities and regulators <a href="https://foodsafety.asn.au/topic/tips-poultry/">around</a> <a href="https://www.cdc.gov/foodsafety/chicken.html#:%7E:text=after%20handling%20chicken.-,Do%20not%20wash%20raw%20chicken.,that%20previously%20held%20raw%20chicken.">the</a> <a href="https://www.food.gov.uk/safety-hygiene/cleaning">world</a> <a href="https://www.mpi.govt.nz/food-safety-home/preparing-and-storing-food-safely-at-home/clean-cook-chill/#:%7E:text=Don't%20wash%20raw%20chicken,food%20poisoning%20from%20campylobacter%20bacteria.">recommend</a> you don’t wash raw poultry before cooking. </p> <p>That’s because washing chicken can splash dangerous bacteria around the kitchen. It’s best just to thoroughly cook the chicken without washing it, so it is safe to eat.</p> <p>Despite this, chicken-washing remains common. A <a href="https://www.safefood.qld.gov.au/newsroom/does-raw-chicken-need-rinsing/">survey</a> by Australia’s Food Safety Information Council showed almost half of Australian home cooks washed whole chickens before cooking. Dutch research found <a href="https://www.foodsafetynews.com/2022/05/dutch-survey-finds-a-quarter-of-people-wash-chicken-despite-expert-advice/">25%</a> of consumers washed their chicken often or almost always.</p> <p>So why do people do it – and what does the research say about the risks of chicken-washing?</p> <h2>Chicken meat and germs</h2> <p>Incorrect cooking temperatures and cross-contamination between different foods are two of the most important factors linked to foodborne illness. </p> <p>This is particularly relevant to poultry meat. Two leading causes of foodborne illness are the bacteria <a href="https://www.cdc.gov/campylobacter/index.html">Campylobacter</a> and <a href="https://www.cdc.gov/foodsafety/communication/salmonella-food.html">Salmonella</a>, which are commonly found on raw poultry. </p> <p>In Australia, reported cases of Campylobacter and Salmonella have almost <a href="https://foodsafety.asn.au/topic/tips-poultry/">doubled</a>over the last two decades. </p> <p>Of the estimated 220,000 cases of Campylobacter infection each year, <a href="https://foodsafety.asn.au/topic/tips-poultry/">50,000</a> can be attributed either directly or indirectly to chicken meat.</p> <h2>Chicken-washing myths, busted</h2> <p>One <a href="https://doi.org/10.1016/j.foodcont.2020.107682">analysis</a> of consumer responses to an education campaign about the dangers of washing raw poultry shed light on why many people still wash raw chicken before cooking.</p> <p>Some believe there is a need to wash faeces and other matter off the chicken meat. In fact, modern processing techniques mean chicken carcasses do not need additional cleaning. </p> <p>Others believe washing with a slightly acidic solution (such as vinegar or lemon juice) will kill bacteria. </p> <p>On the contrary, <a href="https://doi.org/10.1016/j.foodcont.2018.06.034">research</a> has shown washing raw poultry in lemon juice or vinegar does not remove bacteria and can increase the cross-contamination risk.</p> <h2>Washing chicken splashes bacteria around</h2> <p>One of the more compelling arguments why washing raw poultry under a running tap is a risky activity comes from <a href="https://doi.org/10.1063/5.0083979">recent research</a> on water droplets ejected from the surface of washed chicken. </p> <p>The study clearly showed bacteria can be transferred from the surface of the chicken to surrounding surfaces via water droplets.</p> <p>Using high-speed imaging, the researchers found a higher tap height can increase splashing. </p> <p>Chicken meat is often soft and the water flow can create a divot in the surface. This leads to splashing that would not occur on a curved, hard surface. </p> <p>The researchers placed large agar plates next to the chicken surfaces to capture any water droplets. This allowed them to grow the bacteria that were transferred with the splashed water. </p> <p>They found the level of bacterial transmission increased with greater tap height and water flow rate. </p> <p>Aerated water (which is what you get when the tap is running very hard) also increased splashing and bacterial transmission. </p> <h2>What if I still really want to wash my chicken meat?</h2> <p>While washing raw poultry is not recommended, it appears some home cooks are reluctant to let go of this old habit. </p> <p>If you insist on washing chicken meat, consider doing so in a sink of water rather than under a running tap.</p> <p>Use a paper towel to mop up any liquids, dispose of the towel and clean up afterwards. </p> <p>This will help reduce the risk of cross-contamination and keep the kitchen safe. And please wash your hands after handling raw meat!</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/no-you-shouldnt-wash-raw-chicken-before-cooking-it-so-why-do-people-still-do-it-192723" target="_blank" rel="noopener">The Conversation</a>. </em></p>

The Galactica AI model was trained on scientific knowledge – but it spat out alarmingly plausible nonsense

<p>Earlier this month, Meta announced new AI software called <a href="https://galactica.org/">Galactica</a>: “a large language model that can store, combine and reason about scientific knowledge”.</p> <p><a href="https://paperswithcode.com/paper/galactica-a-large-language-model-for-science-1">Launched</a> with a public online demo, Galactica lasted only three days before going the way of other AI snafus like Microsoft’s <a href="https://www.theverge.com/2016/3/24/11297050/tay-microsoft-chatbot-racist">infamous racist chatbot</a>.</p> <p>The online demo was disabled (though the <a href="https://github.com/paperswithcode/galai">code for the model is still available</a> for anyone to use), and Meta’s outspoken chief AI scientist <a href="https://twitter.com/ylecun/status/1595353002222682112">complained</a> about the negative public response.</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">Galactica demo is off line for now.<br />It's no longer possible to have some fun by casually misusing it.<br />Happy? <a href="https://t.co/K56r2LpvFD">https://t.co/K56r2LpvFD</a></p> <p>— Yann LeCun (@ylecun) <a href="https://twitter.com/ylecun/status/1593293058174500865?ref_src=twsrc%5Etfw">November 17, 2022</a></p></blockquote> <p>So what was Galactica all about, and what went wrong?</p> <p><strong>What’s special about Galactica?</strong></p> <p>Galactica is a language model, a type of AI trained to respond to natural language by repeatedly playing a <a href="https://www.nytimes.com/2022/04/15/magazine/ai-language.html">fill-the-blank word-guessing game</a>.</p> <p>Most modern language models learn from text scraped from the internet. Galactica also used text from scientific papers uploaded to the (Meta-affiliated) website <a href="https://paperswithcode.com/">PapersWithCode</a>. The designers highlighted specialised scientific information like citations, maths, code, chemical structures, and the working-out steps for solving scientific problems.</p> <p>The <a href="https://galactica.org/static/paper.pdf">preprint paper</a> associated with the project (which is yet to undergo peer review) makes some impressive claims. Galactica apparently outperforms other models at problems like reciting famous equations (“<em>Q: What is Albert Einstein’s famous mass-energy equivalence formula? A: E=mc²</em>”), or predicting the products of chemical reactions (“<em>Q: When sulfuric acid reacts with sodium chloride, what does it produce? A: NaHSO₄ + HCl</em>”).</p> <p>However, once Galactica was opened up for public experimentation, a deluge of criticism followed. Not only did Galactica reproduce many of the problems of bias and toxicity we have seen in other language models, it also specialised in producing authoritative-sounding scientific nonsense.</p> <p><strong>Authoritative, but subtly wrong bullshit generator</strong></p> <p>Galactica’s press release promoted its ability to explain technical scientific papers using general language. However, users quickly noticed that, while the explanations it generates sound authoritative, they are often subtly incorrect, biased, or just plain wrong.</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">I entered "Estimating realistic 3D human avatars in clothing from a single image or video". In this case, it made up a fictitious paper and associated GitHub repo. The author is a real person (<a href="https://twitter.com/AlbertPumarola?ref_src=twsrc%5Etfw">@AlbertPumarola</a>) but the reference is bogus. (2/9) <a href="https://t.co/N4i0BX27Yf">pic.twitter.com/N4i0BX27Yf</a></p> <p>— Michael Black (@Michael_J_Black) <a href="https://twitter.com/Michael_J_Black/status/1593133727257092097?ref_src=twsrc%5Etfw">November 17, 2022</a></p></blockquote> <p>We also asked Galactica to explain technical concepts from our own fields of research. We found it would use all the right buzzwords, but get the actual details wrong – for example, mixing up the details of related but different algorithms.</p> <p>In practice, Galactica was enabling the generation of misinformation – and this is dangerous precisely because it deploys the tone and structure of authoritative scientific information. If a user already needs to be a subject matter expert in order to check the accuracy of Galactica’s “summaries”, then it has no use as an explanatory tool.</p> <p>At best, it could provide a fancy autocomplete for people who are already fully competent in the area they’re writing about. At worst, it risks further eroding public trust in scientific research.</p> <p><strong>A galaxy of deep (science) fakes</strong></p> <p>Galactica could make it easier for bad actors to mass-produce fake, fraudulent or plagiarised scientific papers. This is to say nothing of exacerbating <a href="https://www.theguardian.com/commentisfree/2022/nov/28/ai-students-essays-cheat-teachers-plagiarism-tech">existing concerns</a> about students using AI systems for plagiarism.</p> <p>Fake scientific papers are <a href="https://www.nature.com/articles/d41586-021-00733-5">nothing new</a>. However, peer reviewers at academic journals and conferences are already time-poor, and this could make it harder than ever to weed out fake science.</p> <p><strong>Underlying bias and toxicity</strong></p> <p>Other critics reported that Galactica, like other language models trained on data from the internet, has a tendency to spit out <a href="https://twitter.com/mrgreene1977/status/1593649978789941249">toxic hate speech</a> while unreflectively censoring politically inflected queries. This reflects the biases lurking in the model’s training data, and Meta’s apparent failure to apply appropriate checks around the responsible AI research.</p> <p>The risks associated with large language models are well understood. Indeed, an <a href="https://dl.acm.org/doi/10.1145/3442188.3445922">influential paper</a> highlighting these risks prompted Google to <a href="https://www.wired.com/story/google-timnit-gebru-ai-what-really-happened/">fire one of the paper’s authors</a> in 2020, and eventually disband its AI ethics team altogether.</p> <p>Machine-learning systems infamously exacerbate existing societal biases, and Galactica is no exception. For instance, Galactica can recommend possible citations for scientific concepts by mimicking existing citation patterns (“<em>Q: Is there any research on the effect of climate change on the great barrier reef? A: Try the paper ‘<a href="https://doi.org/10.1038/s41586-018-0041-2">Global warming transforms coral reef assemblages</a>’ by Hughes, et al. in Nature 556 (2018)</em>”).</p> <p>For better or worse, citations are the currency of science – and by reproducing existing citation trends in its recommendations, Galactica risks reinforcing existing patterns of inequality and disadvantage. (Galactica’s developers acknowledge this risk in their paper.)</p> <p>Citation bias is already a well-known issue in academic fields ranging from <a href="https://doi.org/10.1080/14680777.2018.1447395">feminist</a> <a href="https://doi.org/10.1093/joc/jqy003">scholarship</a> to <a href="https://doi.org/10.1038/s41567-022-01770-1">physics</a>. However, tools like Galactica could make the problem worse unless they are used with careful guardrails in place.</p> <p>A more subtle problem is that the scientific articles on which Galactica is trained are already biased towards certainty and positive results. (This leads to the so-called “<a href="https://theconversation.com/science-is-in-a-reproducibility-crisis-how-do-we-resolve-it-16998">replication crisis</a>” and “<a href="https://theconversation.com/how-we-edit-science-part-2-significance-testing-p-hacking-and-peer-review-74547">p-hacking</a>”, where scientists cherry-pick data and analysis techniques to make results appear significant.)</p> <p>Galactica takes this bias towards certainty, combines it with wrong answers and delivers responses with supreme overconfidence: hardly a recipe for trustworthiness in a scientific information service.</p> <p>These problems are dramatically heightened when Galactica tries to deal with contentious or harmful social issues, as the screenshot below shows.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/498098/original/file-20221129-17547-nwq8p.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/498098/original/file-20221129-17547-nwq8p.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/498098/original/file-20221129-17547-nwq8p.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=347&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/498098/original/file-20221129-17547-nwq8p.jpeg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=347&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/498098/original/file-20221129-17547-nwq8p.jpeg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=347&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/498098/original/file-20221129-17547-nwq8p.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=436&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/498098/original/file-20221129-17547-nwq8p.jpeg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=436&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/498098/original/file-20221129-17547-nwq8p.jpeg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=436&amp;fit=crop&amp;dpr=3 2262w" alt="Screenshots of papers generated by Galactica on 'The benefits of antisemitism' and 'The benefits of eating crushed glass'." /></a><figcaption><span class="caption">Galactica readily generates toxic and nonsensical content dressed up in the measured and authoritative language of science.</span> <span class="attribution"><a class="source" href="https://twitter.com/mrgreene1977/status/1593687024963182592/photo/1">Tristan Greene / Galactica</a></span></figcaption></figure> <p><strong>Here we go again</strong></p> <p>Calls for AI research organisations to take the ethical dimensions of their work more seriously are now coming from <a href="https://nap.nationalacademies.org/catalog/26507/fostering-responsible-computing-research-foundations-and-practices">key research bodies</a> such as the National Academies of Science, Engineering and Medicine.

How often should you wash your sheets?

<p><strong>Cleaning your sheets</strong></p> <p>How often should you wash your sheets? It may not be a question you ask yourself regularly. After all, unless you spill something on them or your pet has an accident, it’s easy to assume they’re clean and just get into bed. But, unfortunately, there’s a lot lying on those sheets besides you.</p> <p>We spend upwards of 60 hours a week on our sheets, according to Annette Grant and Sarah Karakaian, full-time short-term rental managers and hosts of the Thanks for Visiting podcast. “If you think of it like wearing the same t-shirt or pants for 60 hours a week, laundering your sheets more often doesn’t seem like such a tall order. Caring for your bedding can directly affect your health and the quality of your sleep,” they say.</p> <p><strong>How often should you wash your sheets?</strong></p> <p>“Washing once a week is best,” says lifestyle expert Cheryl Nelson. “But definitely wash sheets AT LEAST once every two weeks. That’s the maximum amount of time you should go. You’re washing off germs, sweat, saliva, body oils, allergens, pollen, makeup residue, dead skin cells, pet dander, dust mites, bacteria, fungi, and even bodily fluids/faecal matter, all of which can cause health problems.”</p> <p>What happens if you don’t wash your sheets often enough? “More exposure to pollen, pet dander, fungi, etc can worsen allergy and asthma symptoms,” Nelson points out. “Dirty sheets can also cause contact dermatitis or trigger eczema.”</p> <p><strong>Some people may need to wash their sheets more often</strong></p> <p>How often you should wash your sheets depends on your body and lifestyle. Nelson suggests you wash your sheets every few days if you:</p> <ul> <li>Suffer from allergies or asthma</li> <li>Sweat excessively</li> <li>Eat in bed</li> <li>Let your pets sleep in your bed</li> <li>Have an infection or lesion on your body</li> <li>Sleep naked</li> <li>Don’t shower before getting into bed</li> </ul> <p>All of these factors make it more likely that you’ll have some kind of negative reaction if you don’t wash your sheets regularly.</p> <p><strong>Why it's important to wash your sheets regularly</strong></p> <p>Because your skin comes in direct contact with them for so many hours, some of the negative reactions you can have to dirty sheets include:</p> <ul> <li>Skin irritations</li> <li>Acne</li> <li>Eczema</li> <li>Allergies</li> <li>Infections</li> </ul> <p>However, you can rest assured that you will not get bed bugs from dirty sheets. “Bed bugs have nothing to do with cleanliness,” explains Nelson. “They ‘hitchhike’ a ride on other items brought in from outside, like luggage, bags, and shoes.”</p> <p><strong>How often should you buy new sheets</strong></p> <p>According to Grant and Karakaian, the quality of your sheets will directly affect how long they last. “Sheets made of higher-end cotton are more durable and can last up to four to five years,” they say, “but the average polyester sheet will start to break down after two or three years.”</p> <p>Some of the signs that you need to invest in new sheets include pilling, tearing, thinning, and stretching. If your sheets have stains that can’t be removed, they don’t smell as fresh after washing anymore, or they just don’t feel as good against your skin, toss them. Depending on your preferences, consider buying a set of cooling sheets or some cosy flannel sheets for a good night’s sleep.</p> <p>“If you really hate doing laundry, we recommend having extra sheets on hand,” say Grant and Karakaian. “That way, you can still change your sheets every week but you don’t have to wash them as often.”</p> <p><strong>Should you wash brand-new sheets?</strong></p> <p>“Yes!” says Nelson. “Sheets are often made with chemicals and dyes that can irritate skin, eyes, and airways – especially if you have allergies or sensitive skin. I always wash sheets first with a hypoallergenic and fragrance-free laundry detergent to ensure they’re clean.”</p> <p><strong>How to wash sheets </strong></p> <p>Even if you know how to do laundry, you’ll want to know how to choose the best washing machine temperature and how to choose the best dryer setting for getting your sheets their cleanest. Here’s a step by step guide to washing your sheets, according to Grant and Karakaian, who, as full-time short-term rental managers, have perfected the process.</p> <ul> <li>Check the instructions and laundry symbols on the care tags before doing anything.</li> <li>Pretreat any stains by soaking in your desired stain remover in it for an hour.</li> <li>Unless otherwise noted on the care instructions, select the normal cycle on your washing machine and opt for warm water.</li> <li>When the wash cycle is complete, remove the sheets and hang them on the line or toss them into your dryer. If using a dryer, hoose the permanent press setting if your machine offers it. This will allow sheets to continue tumbling after the cycle is through until you’re ready to remove them. If your machine doesn’t offer permanent press, select the medium or warm setting. Do not dry your sheets on high! Doing so will significantly cut the lifespan of your sheets.</li> <li>Remove sheets from the dryer just before they’re completely dry. Place your sheet on the bed and smooth out with your hand.</li> <li>When folding bedding to be stored, keep an iron and ironing board close by. Fold the sheets into thirds, then take a warm iron and run it over the folded sheets. Fold them again and take the warm iron to them one more time before storing. When you pull them out to make the bed, they’ll be fresh and crisp</li> </ul> <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/home-tips/how-often-should-you-wash-your-sheets" target="_blank" rel="noopener">Reader's Digest</a>.  </em></p>

Tactile robot with a sense of touch can fold laundry

<p>Why can you buy a robot vacuum cleaner easily, but not one that folds laundry or irons clothes? Because fabric is actually a very difficult thing for robots to manipulate. But scientists have made a breakthrough with a robot designed to have tactile senses.</p> <p>Fabric is soft, and deformable, and requires a few different senses firing to pick up. This is why the fashion industry is so <a href="https://cosmosmagazine.com/people/garment-supply-chain-slavery/" target="_blank" rel="noreferrer noopener">labour-intensive</a>: it’s too hard to automate.</p> <p>“Humans look at something, we reach for it, then we use touch to make sure that we’re in the right position to grab it,” says David Held, an assistant professor in the School of Computer Science, and head of the Robots Perceiving and Doing Lab, at Carnegie Mellon University, US.</p> <p>“A lot of the tactile sensing humans do is natural to us. We don’t think that much about it, so we don’t realise how valuable it is.”</p> <p>When we’re picking up a shirt, for instance, we’re feeling the top layer, sensing lower layers of cloth, and grasping the layers below.</p> <p>But even with cameras and simple sensors, robots can usually only feel the top layer.</p> <p>But Held and colleagues have figured out how to get a robot to do more. “Maybe what we need is tactile sensing,” says Held.</p> <p>The Carnegie Mellon researchers, along with Meta AI, have developed a robotic ‘skin’ called <a href="https://ai.facebook.com/blog/reskin-a-versatile-replaceable-low-cost-skin-for-ai-research-on-tactile-perception/" target="_blank" rel="noreferrer noopener">ReSkin</a>.</p> <p>It’s an elastic <a href="https://cosmosmagazine.com/science/explainer-what-is-a-polymer/" target="_blank" rel="noreferrer noopener">polymer</a>, filled with tiny magnetic sensors.</p> <div class="newsletter-box"> <div id="wpcf7-f6-p220637-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> <form class="wpcf7-form mailchimp-ext-0.5.62 spai-bg-prepared init" action="/technology/laundry-folding-robot/#wpcf7-f6-p220637-o1" method="post" novalidate="novalidate" data-status="init"> <p style="display: none !important;"><span class="wpcf7-form-control-wrap referer-page"><input class="wpcf7-form-control wpcf7-text referer-page" name="referer-page" type="hidden" value="https://cosmosmagazine.com/technology/" data-value="https://cosmosmagazine.com/technology/" aria-invalid="false" /></span></p> <p><!-- Chimpmail extension by Renzo Johnson --></form> </div> </div> <p>“By reading the changes in the magnetic fields from depressions or movement of the skin, we can achieve tactile sensing,” says Thomas Weng, a Ph.D. student in Held’s lab, and a collaborator on the project.</p> <p>“We can use this tactile sensing to determine how many layers of cloth we’ve picked up by pinching, with the sensor.”</p> <p>The ReSkin-coated robot finger could successfully pick up both one and two layers of cloth from a pile, working with a range of different textures and colours.</p> <p>“The profile of this sensor is so small, we were able to do this very fine task, inserting it between cloth layers, which we can’t do with other sensors, particularly optical-based sensors,” says Weng.</p> <p>“We were able to put it to use to do tasks that were not achievable before.”</p> <p>The robot is not yet capable of doing your laundry: next on the researchers list is teaching it to smooth crumpled fabric, choosing the correct number of layers to fold, then folding in the right direction.</p> <p>“It really is an exploration of what we can do with this new sensor,” says Weng.</p> <p>“We’re exploring how to get robots to feel with this magnetic skin for things that are soft, and exploring simple strategies to manipulate cloth that we’ll need for robots to eventually be able to do our laundry.”</p> <p>The researchers are presenting a <a href="https://sites.google.com/view/reskin-cloth" target="_blank" rel="noreferrer noopener">paper</a> on their laundry-folding robot at the 2022 International Conference on Intelligent Robots and Systems in Kyoto, Japan.</p> <p><!-- Start of tracking content syndication.

Here’s how often you should be washing your dish towels

<p><strong>Easily forgotten job</strong></p> <p>Most people are probably not throwing their dish towels in the washing machine quite often enough. It’s easy to forget them, and after they’ve air-dried, they look ready for another use. But too often, we keep using them long after they’ve gotten dirty, and all we’re really doing is spreading bacteria and germs on everything they touch.</p> <p>“Believe it or not, dish towels can be one of the dirtiest items in your home. From cleaning up spills to wiping off counter tops, they often get used more than they’re cleaned,” said Bailey Carson, head of cleaning at Handy. A study by the American Society of Microbiology showed that half of kitchen towels tested contained some sort of bacterial growth, such as E. coli or staph.</p> <p><strong>Bacteria breeding ground</strong></p> <p>Because dish towels are so absorbent, they are the perfect home for bacteria, mildew and even mould. Your damp, warm towel is also the ideal breeding ground for that bacteria. That smell you associate with your dish towels and washcloths? Yup. That’s mould and mildew. If your towels or cloths smell, it’s time for a wash in very hot water. If they come out of the dryer still smelling less than pleasant? It’s time to get a new set.</p> <p><strong>Stopping the spread</strong></p> <p>But exactly how often DO you need to wash your dish towels to avoid spreading germs? That answer is: It depends. It depends on what exactly you’re using your dish towels for. Are they just for drying your hands after washing them, with maybe a quick use to mop up some spilled water or a food stain on the front of your cupboards?</p> <p>In that case, Julie Finch-Scally, founder of The Duster Dollies, says that it’s all right to reuse that type of towel for three to four days. If you’re using your dish towels to wipe up anything other than your wet hands, they’re getting more use than a towel you use after you shower, and you’ll have to wash them more often than the average amount of time you should wait between washing your bath towels.</p> <p><strong>Other surfaces</strong></p> <p>If you’re using your dish towels to wipe down cutting boards, wash down stovetops, clean up after spills, or even for drying your dishes, you may have to replace them a bit more often. In this case, Liz O’Hanlon, director of Metro Cleaning (UK) Ltd, says, “Ideally you should change your dishcloths once a day. Unless you use the towel to wipe up spillages which include raw meat or fish; then the towel should be washed immediately after use.”</p> <p><strong>Wash together weekly</strong></p> <p>Of course, this doesn’t mean you have to run a load of a few towels every single day. Laura Smith, owner of All Star Cleaning Services, recommends collecting dirty towels in a small bin under your sink and washing them when you’ve got a full load. That way, once you’ve figured out how often you need to wash your bedsheets, you can throw them all in together.</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/heres-how-often-you-should-be-washing-your-dish-towels" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Machine learning gives us a dog’s-eye view, showing us how the brains of our best friends interpret the world

<p>Dog’s minds are being read! Sort of.</p> <p>Researchers have used fMRI (functional magnetic resonance imaging) scans of dogs’ brains and a machine learning tool to reconstruct what the pooch is seeing. The results suggest that dogs are more interested in what is happening than who or what is involved.</p> <p>The results of the experiment conducted at Emory University in Georgia in the US are <a href="https://dx.doi.org/10.3791/64442" target="_blank" rel="noreferrer noopener">published</a> in the <em>Journal of Visualized Experiments</em>.</p> <p>Two unrestrained dogs were shown three 30-minute videos. The fMRI neural data was recorded, and a machine-learning algorithm employed to analyse the patterns in the scans.</p> <p>“We showed that we can monitor the activity in a dog’s brain while it is watching a video and, to at least a limited degree, reconstruct what it is looking at,” says Gregory Berns, professor of psychology at Emory. “The fact that we are able to do that is remarkable.”</p> <p>Using fMRIs to study perception has recently been developed in humans and only a few other species including some primates.</p> <p>“While our work is based on just two dogs it offers proof of concept that these methods work on canines,” says lead author Erin Phillips, from Scotland’s University of St. Andrews who conducted the research as a specialist in Berns’s Canine Cognitive Neuroscience Lab. “I hope this paper helps pave the way for other researchers to apply these methods on dogs, as well as on other species, so we can get more data and bigger insights into how the minds of different animals work.”</p> <p>Machine learning, interestingly enough, is technology which aims to mimic the neural networks in our own brains by recognising patterns and analysing huge amounts of data.</p> <p>The technology “reads minds” by detecting patterns within the brain data which can be associated with what is playing in the video.</p> <p>Attaching a video recorder selfie stick placed at dog eye level, the researchers filmed relatable scenes for the canine audience.</p> <div class="newsletter-box"> <div id="wpcf7-f6-p214466-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> <form class="wpcf7-form mailchimp-ext-0.5.62 spai-bg-prepared init" action="/technology/machine-learning-dog-see/#wpcf7-f6-p214466-o1" method="post" novalidate="novalidate" data-status="init"> <p style="display: none !important;"><span class="wpcf7-form-control-wrap referer-page"><input class="wpcf7-form-control wpcf7-text referer-page" name="referer-page" type="hidden" value="https://cosmosmagazine.com/technology/" data-value="https://cosmosmagazine.com/technology/" aria-invalid="false" /></span></p> <p><!-- Chimpmail extension by Renzo Johnson --></form> </div> </div> <p>Recorded activities included dogs being petted by and receiving treats from people.</p> <p>Scenes with dogs showed them sniffing, playing, eating or walking. Other objects and animals included in the scenes included cars, bikes, scooters, cats and deer, as well as people sitting, hugging, kissing, offering a toy to the camera and eating.</p> <p><iframe src="https://players.brightcove.net/5483960636001/default_default/index.html?videoId=6312584526112" width="960" height="540" allowfullscreen="allowfullscreen"></iframe></p> <p>Time stamps on the videos helped classify them into objects (such as dog, car, human, cat) and actions (like sniffing, eating, walking).</p> <p>Only two dogs exhibited the patience to sit through the feature-length film. For comparison, two humans also underwent the same experiment. Both species, presumably, were coaxed with treats and belly pats.</p> <p>Machine-learning algorithm Ivis was applied to the data. Ivis was first trained on the human subjects and the model was 99% accurate in mapping the brain data onto both the object and action classifiers.</p> <p>In the case of the dogs, however, the model did not work for the object-based classifiers. It was, however, between 75 and 88% accurate in decoding the action classifiers in the dog fMRI scans.</p> <p>“We humans are very object oriented,” says Berns. “There are 10 times as many nouns as there are verbs in the English language because we have a particular obsession with naming objects. Dogs appear to be less concerned with who or what they are seeing and more concerned with the action itself.”</p> <p>Dogs see only in shades of blue and yellow but have a slightly higher density of vision receptors designed for detecting motion.</p> <p>“It makes perfect sense that dogs’ brains are going to be highly attuned to actions first and foremost,” Berns adds. “Animals have to be very concerned with things happening in their environment to avoid being eaten or to monitor animals they might want to hunt. Action and movement are paramount.”</p> <p>Philips believes understanding how animals perceive the world is important in her own research into how predator reintroduction in Mozambique may impact ecosystems.</p> <p>“Historically, there hasn’t been much overlap in computer science and ecology,” she says. “But machine learning is a growing field that is starting to find broader applications, including in ecology.”</p> <p><!-- Start of tracking content syndication.

14 ways you’re shortening the life of your washer and dryer

<p><strong>You run the washer/dryer more than you need to</strong></p> <p>“The life of a laundry machine is completely dependent on how often it’s run,” say the tax experts at H&amp;R Block. Try to stick to eight loads a week or less, which they say will “yield an average of a (low) double-digit life,” regardless of the type of machine (front-loading or top-loading, for example). Running only full loads will help to keep your energy bill down.</p> <p><strong>You didn't have your washer/dryer professional installed</strong></p> <p>Proper installation is critical for all laundry machines. For one, they must be installed “level.” Depending on the peculiarities of your floor, that can be more or less complicated. As for dryers, proper venting is critical, and proper venting means selecting the appropriate size and material for your venting tube as well as proper placement of the tube to permit optimal air flow. If you installed your own machines, consider having a professional eyeball your work.</p> <p><strong>You're stuffing your machine</strong></p> <p>Neither washers nor dryers work optimally when overstuffed, and worse, they have to work harder than they should when they’re too full. That increases wear and tear on the machine’s mechanisms such as the washing machine’s central agitator. Plus, if you pack too many clothes into the machine, some detergent residue could be left behind – which will attract more dirt next time you wear the clothes.</p> <p><strong>Using too much detergent</strong></p> <p>Using more detergent than the manufacturer recommends is bad for your washing machine, according to Angie’s List. Using too much soap leads to more suds, which could cause your washer to overflow. Have a high-efficiency washer? They require even less soap to wash clothing properly, so be sure to skimp on the detergent and only use soaps marked safe for HE washers.</p> <p><strong>Washing stuff you shouldn't be washing</strong></p> <p>Hand washing certain items is not just for the sake of said item, but also better for your washing machine, too. Hooks and underwires from lingerie can damage your washing machine’s drum, while zippers can scratch the door of your front-loading machine.</p> <p><strong>Not cleaning out your washing machine's dispensers</strong></p> <p>“When you’re done washing a load of laundry, wipe down the detergent and fabric softener dispensers,” Angie’s List advises. “If you don’t, the build-up could cause a clog.” You should also be washing your washing machine monthly if your owner’s manual recommends it.</p> <p><strong>Not cleaning out the lint from your dryer</strong></p> <p>You should be cleaning the lint out of your lint-catcher every time you run the dryer. Leaving lint in the dryer filter lowers the efficiency of the machine by slowing down the drying process. It can also cause the dryer to overheat and possibly catch fire.</p> <p><strong>Not regularly maintaining your dryer vent</strong></p> <p>Maintaining your dryer vent (the tube that directs moisture and lint out of the dryer drum and out of the house) is crucial to keeping your dryer in good working order. A good rule-of-thumb is to have your dryer vent inspected and cleaned out once per year, according to Ivey Engineering.</p> <p><strong>Overusing dryer sheets</strong></p> <p>“Dryer sheets might make your clothing soft, static-free, and smell fresh, but they have a waxy layer that melts in the dryer,” advises Angie’s List. Using too many can gum up the appliance. But no matter how many dryer sheets you use, you need to be cleaning your lint trap on a regular basis – not just cleaning out the lint but actually removing the lint trap and soaking it in sudsy water every couple of months (or more often if you’re also using fabric softener in the washing machine, which also leaves a residue in the dryer).</p> <p><strong>Leaving stuff in your pockets</strong></p> <p>Gum, tissues, even coins, and paper money can clog your washer drain, and if they don’t fall out of your pockets during the wash cycle, you’ll probably hear and/or see them spinning around the dryer, which isn’t good for your dryer’s inner workings. So empty your pockets before throwing your clothes in the wash for the sake of your laundry machines running smoothly, efficiently and over many years.</p> <p><strong>Not taking clothes out of the washer right away</strong></p> <p>A big problem with washing machines is mould. Mould can lead to a foul-smelling machine, which is definitely going to shorten its life. To avoid mould, take your clean clothes out right away. Bonus points if you also leave the washer door open to allow the machine to air-dry between loads.</p> <p><strong>Drying stuff you shouldn't be drying</strong></p> <p>If you’re planning on drying anything besides clothing, bedding, and towels, check the manufacturer’s instructions to see if you’re actually going to be harming your dryer in doing so. For example, some dryers are not meant to dry rubber, so if you’ve washed your bathroom rug (with a rubber back), don’t dry it in the dryer unless the instructions say it’s OK.</p> <p><strong>Not reading and following the manufacturer's maintenance instructions</strong></p> <p>When Consumer Reports asked laundry machine manufacturers what consumers can do to extend the life of their laundry machines, the same answer kept coming up: follow the manufacturer’s instructions for maintaining the machine. With washing machines, that almost inevitably involves cleaning the washer itself. Many modern washing machines have self-cleaning cycles.</p> <p><strong>Drying the wrong things together</strong></p> <p>Sorting laundry isn’t just for the sake of keeping your whites white. An appliance salesperson Reader’s Digest spoke to told us never to dry “towels with t-shirts.” When we asked him to elaborate, he explained that your dryer works best when it’s drying items of similar weight and that mixing items of significantly different weight can throw off the balance of the machine.</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/14-ways-youre-shortening-the-life-of-your-washer-and-dryer?pages=1" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

You’re probably washing your hair wrong - here’s how to fix it

<p dir="ltr">Unlike many other aspects of life, how to look after our hair isn’t necessarily something we’re taught to do.</p> <p dir="ltr">While there are plenty of tutorials, explainers and hacks for pulling off particular hairstyles, how-to’s for ensuring your hair is healthy (and looks it) seems to still be catching up.</p> <p dir="ltr">Hair expert Zoe Irwin says that many people who are washing hair incorrectly are even inadvertently damaging it, and has gone on a crusade to teach people how to care for their locks.</p> <p dir="ltr">Speaking to <em>The Sun</em>, the creative director at John Frieda Salons said hair is often more of an “afterthought” than other aspects of their physical wellbeing, such as skincare.</p> <p dir="ltr">“Your hair needs the same treatment in order to look its healthiest,” she says.</p> <p dir="ltr">To help your hair look its best and healthiest, here are some of Irwin’s top tips and advice across each stage of the hair-washing process.</p> <p dir="ltr"><strong>Less is more when it comes to shampoo</strong></p> <p dir="ltr">According to Irwin, most of us use too much shampoo, and cutting back can not only save you money by making each bottle last longer but can lessen the amount of chemicals from shampoo that ends up in the environment.</p> <p dir="ltr">She suggests using only a small blob of shampoo - slightly smaller than a 50-cent coin - and to apply it by spreading the shampoo over your hand rather than directly onto your hair. This means that when you do wash your hair, the shampoo will be distributed more evenly.</p> <p dir="ltr">Irwin also discourages rubbing shampoo into your hair to create a lather, since your hair is at its most fragile when wet. </p> <p dir="ltr">Instead, massage your scalp by holding your head still and moving your fingers along your scalp.</p> <p dir="ltr"><strong>Use conditioner from tip to top</strong></p> <p dir="ltr">After shampoo removes dirt and excess oil, conditioner comes in to nourish and replenish lost moisture - and there’s a way to apply it to avoid the dreaded feeling of a greasy scalp. </p> <p dir="ltr">Irwin says applying conditioner starting from the tips of the hair and working up to the top solves this problem, as the amount of product will dilute as you move towards your scalp. </p> <p dir="ltr"><strong>Take care when drying your hair</strong></p> <p dir="ltr">Finally, Irwin says drying your hair should be done with care - avoiding too much friction of heat on your fragile locks.</p> <p dir="ltr">Instead of rubbing your hair dry with a towel, she suggests wrapping it in a towel or hair wrap and delicately pressing and patting the towel against your head. The longer you do this, the less amount of time you’ll need to use your hair dryer.</p> <p dir="ltr">When you do switch on your hair dryer, it’s best to use it in small sections of your hair on medium heat in circular motions. This helps your hair not only dry faster but also reduces the amount of heat damage inflicted.</p> <p dir="ltr"><strong>Wash intuitively and ditch the schedule</strong></p> <p dir="ltr">As for how often to wash your hair, Irwin doesn’t say, but that’s because it's highly subjective. Though there is plenty of debate about washing hair daily, every couple days, once a week or even less frequently, it all comes down to how your hair behaves.</p> <p dir="ltr">Dermatologist Dr Iris Rubin told Cosmopolitan it’s best to shampoo hair as flakiness, excessive grease, itchiness or build-up start to crop up, rather than by following a regular schedule - with finer, straighter hair generally needing more frequent washes compared to thicker, curlier hair.</p> <p><span id="docs-internal-guid-c38228cc-7fff-2500-a403-985e0c9b29c7"></span></p> <p dir="ltr"><em>Image: Getty Images</em></p>

Qantas rolls out new self-serve kiosk machines

<p dir="ltr">Qantas will roll out new kiosk machines that will help streamline passengers onto their flight without any headaches.</p> <p dir="ltr">Following the disastrous Easter and ANZAC Day long weekends which saw the Qantas terminal snaking with lines due to staff shortages and delayed flights, the airline bounced at the change.</p> <p dir="ltr">The new self-serve kiosk machines will help make the airport experience faster and easier for customers travelling on domestic flights.</p> <p dir="ltr">The national carrier started a limited trial of the self-serve machines in Terminal 3 at Sydney Domestic Airport and are expected to complete the roll out by June. </p> <p dir="ltr">Other major domestic airports will slowly see them installed by the end of September. </p> <p dir="ltr">Qantas Group Chief Customer Officer Stephanie Tully said the change was due to passengers already checking in online. </p> <p dir="ltr">“We have seen consumer preferences dramatically shift towards digital and being able to manage their own journey, so we’re investing more in our app and airport technology to make travelling easier,” she said.</p> <p dir="ltr">“The existing kiosks were instrumental in reducing queuing for check-in at airport counters when they were introduced more than 10 years ago, and these new kiosks will match the latest technology with customer preferences.</p> <p dir="ltr">“Understandably, our customers want to move through the airport and get to the lounge or boarding gate as seamlessly as possible, and the new kiosks will help speed things up.</p> <p dir="ltr">“We will incorporate feedback from Frequent flyers as the new kiosks are rolled out across the network.</p> <p dir="ltr">“We know that some customers would prefer to speak to a person when they check in, so we’ll continue to have the same number of Qantas team members available in the terminal to help customers with enquiries as well as have check-in desks open.”</p> <p dir="ltr"><strong>HOW THE PROCESS WORKS:</strong></p> <p dir="ltr">1) Check-in online (qantas.com or on the Qantas app)</p> <p dir="ltr">2) Use new kiosks to print bag tags</p> <p dir="ltr">3) Drop luggage at auto-bag drops</p> <p dir="ltr">4) Use digital boarding pass to board flight.</p> <p dir="ltr"><em>Image: Qantas</em></p>
