Steve Price slams woman's savvy Airtasker job

Steve Price has launched into a tirade on The Project over a story about a woman's savvy use of Airtasker. The Sydney woman posted a job on the site to pay a stranger $100 if they delivered her a pair of sneakers to the Ivy nightclub, after her high heels began hurting her feet at 1am. Her ingenuity quickly went viral, with The Project panellist Georgie Tunny explaining the situation. "Someone came through (and delivered the shoes), and her followers applauded her, calling it genius hack," Tunny said. <div class="embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border: 0px; font-size: 15px; vertical-align: baseline; outline: currentcolor !important;"><iframe class="embedly-embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border-width: 0px; border-style: none; vertical-align: baseline; width: 591px; outline: currentcolor !important;" title="tiktok embed" src="https://cdn.embedly.com/widgets/media.html?src=https%3A%2F%2Fwww.tiktok.com%2Fembed%2Fv2%2F7476683192787946770&display_name=tiktok&url=https%3A%2F%2Fwww.tiktok.com%2F%40aimee.clairee%2Fvideo%2F7476683192787946770%3Fembed_source%3D121374463%252C121468991%252C121439635%252C121433650%252C121404359%252C121497414%252C73319236%252C121477481%252C121351166%252C121487028%252C73347567%252C121331973%252C120811592%252C120810756%252C121503376%253Bnull%253Bembed_masking%26refer%3Dembed%26referer_url%3Dwww.dailymail.co.uk%252Ftvshowbiz%252Farticle-14454879%252FThe-Project-Steve-Price-sneakers-nightclub-heels.html%26referer_video_id%3D7476683192787946770&image=https%3A%2F%2Fp16-sign-sg.tiktokcdn.com%2Fobj%2Ftos-alisg-p-0037%2Fo4gbklEViYI8Bu8LPiDDiBnRVC8KAIVEAZBDy%3Flk3s%3Db59d6b55%26x-expires%3D1741222800%26x-signature%3Dr1zBofQ2NEGTc0Et0FGfYs3KRQY%253D%26shp%3Db59d6b55%26shcp%3D-&type=text%2Fhtml&schema=tiktok" width="340" height="700" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe></div> Steve Price, however, wasn't impressed by the woman's determination to be comfortable, blasting her "ridiculous" request. Price crinkled his face in disgust at the harmless story and let loose, mincing no words as he shared his opinion. "Don't be stupid. That's the most ridiculous, over-privileged w**ky thing I've heard of" he said. "That woman has too much money. She got secondhand smelly sneakers," Steve added. Georgie defended the woman, saying that in her clubbing days, she would absolutely have paid someone a decent sum in order to be in comfortable shoes and spare her feet. Image credits: The Project

Summer holidays haven’t changed much since ancient Greece and Rome (except maybe the sand wrestling)

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/konstantine-panegyres-1528527">Konstantine Panegyres</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Imagine a summer holiday at a seaside resort, with days spent sunbathing, reading books, exploring nature and chatting with friends. Sounds like it could be anywhere in Australia or New Zealand in January, doesn’t it? This is also how the Roman emperor <a href="https://oxfordre.com/classics/display/10.1093/acrefore/9780199381135.001.0001/acrefore-9780199381135-e-3508?product=orecla">Julian</a> spent his summers in the 4th century CE. Towards the end of 357 CE, Julian wrote a <a href="https://www.loebclassics.com/view/emperor_julian-letters/1923/pb_LCL157.79.xml?rskey=Sa5rUn&result=1&mainRsKey=pqeNrD">letter</a> to his friend Evagrius, telling him how he spent his holidays at his grandmother’s estate as a boy and young man: <blockquote> Very peaceful it is to lie down there and glance into some book, and then, while resting one’s eyes, it is very agreeable to gaze at the ships and the sea. When I was still hardly more than a boy I thought that this was the most delightful summer residence, for it has, moreover, excellent springs and a charming bath and garden and trees. </blockquote> As Julian got older, though, he had less time for summer holidays. Work consumed him. Even when he was on a break, he couldn’t fully relax. This might sound familiar, too. It seems very little has changed from the days of the ancient Greek and Roman empires when it comes to finding time to unwind – and being on holidays, too. <h2>Finding time for a break</h2> Taking time off was important in ancient Greek and Roman times. Even <a href="https://www.tandfonline.com/doi/pdf/10.1080/00397677908590731">Greek and Roman slaves</a> were permitted to take a few holidays each year. Not everyone could enjoy their holidays, however. In 162 CE, <a href="https://oxfordre.com/classics/display/10.1093/acrefore/9780199381135.001.0001/acrefore-9780199381135-e-984">Marcus Aurelius</a>, then emperor of Rome, took four days of holiday at a resort in Alsium, a city on the coast of modern-day Italy. According to his friend <a href="https://oxfordre.com/classics/display/10.1093/acrefore/9780199381135.001.0001/acrefore-9780199381135-e-1846">Marcus Cornelius Fronto</a> (c. 95-166 CE), though, the emperor could not stop working. In a letter, Fronto <a href="https://www.loebclassics.com/view/marcus_cornelius_fronto-correspondence/1919/pb_LCL113.5.xml?mainRsKey=Q5rXrd&result=1&rskey=fAbCGr">criticises</a> Marcus for continuing to work hard rather than sleeping in, exploring the seaside, rowing on the ocean, bathing and feasting on seafood. Fronto amusingly says that Marcus, rather than enjoy his holiday, has instead “declared war on play, relaxation, good living, and pleasure”. <h2>Going to the seaside</h2> Relaxing by the coast was one of the things people in ancient Greece and Rome most enjoyed doing in the summer. The rich built summer residences on the coast, while people of all walks of life flocked to seaside resorts to enjoy the fresh air and cool water. The orator <a href="https://oxfordre.com/classics/display/10.1093/acrefore/9780199381135.001.0001/acrefore-9780199381135-e-3675">Libanius</a> (314-393 CE) <a href="https://www.loebclassics.com/view/libanius-oration_45_emperor_prisoners/1977/pb_LCL452.165.xml?rskey=EVUxsK&result=1&mainRsKey=ISthry">wrote</a> that the people who really enjoy life the most are those who have the freedom to “drive to their estates, visit other towns, buy land, and visit the seaside”. Health tourism was also a popular reason why people came to the seaside. Many ancient doctors recommended sea water and air as cures for all kinds of health problems, especially those related to the skin and respiratory system. For example, the doctor <a href="https://oxfordre.com/classics/display/10.1093/acrefore/9780199381135.001.0001/acrefore-9780199381135-e-705">Aretaeus of Cappadocia</a> (c. 150-200 CE) <a href="https://books.google.com.au/books?id=v4gIAAAAIAAJ&pg=PA463&dq=Aretaeus+sea+water&hl=en&newbks=1&newbks_redir=0&sa=X&ved=2ahUKEwjh-f6OiuCJAxW4dPUHHXQQH5oQ6AF6BAgEEAI#v=onepage&q=Aretaeus%20sea%20water&f=false">recommended</a> bathing in sea water, wrestling on sand and living by the sea as therapies for those who get frequent headaches. <h2>Travelling abroad</h2> Visiting foreign places was another of the things people in ancient Greece and Rome most enjoyed doing on their summer holidays. For the Romans, trips to see Greece – and in particular Athens – were especially popular. The Roman general <a href="https://oxfordre.com/classics/display/10.1093/acrefore/9780199381135.001.0001/acrefore-9780199381135-e-3396?rskey=xWdUMg&result=1">Germanicus</a> (15 BCE–19 CE) went on a tour of Greece in 18 CE, travelling from Athens eastward to Euboea, Lesbos, the coast of Asia Minor and then to Byzantium and Pontus. According to the Roman historian <a href="https://oxfordre.com/classics/display/10.1093/acrefore/9780199381135.001.0001/acrefore-9780199381135-e-6205">Tacitus</a>, Germanicus was motivated by a desire to see famous ancient sites. Like many Romans, he was fascinated by the old stories of the Greek past, so <a href="https://www.loebclassics.com/view/tacitus-annals/1931/pb_LCL249.469.xml">he was</a> “eager to make the acquaintance of those ancient and storied regions”. Another popular destination for ancient Greeks and Romans was Egypt, which had always been regarded as a land of wonder. Roman tourists could catch regular boats from <a href="https://www.romanports.org/en/the-ports/88-puteoli.html">Puteoli</a> to the great Egyptian city <a href="https://www.britannica.com/place/Alexandria-Egypt">Alexandria</a>. The trip took anywhere from one to two weeks, stopping along the way in Sicily and Malta. Once there, the highlights were typically the great Nile River and Pyramids. Tourists marvelled at the immense temples and walls of hieroglyphic writing. When Germanicus visited Egypt in 19 CE, he was so curious about the meaning of the hieroglyphics that he <a href="https://www.loebclassics.com/view/LCL249/1931/volume.xml">asked</a> an old Egyptian priest to translate some for him. In Alexandria, another attraction was the tomb of <a href="https://www.oxfordreference.com/display/10.1093/oi/authority.20110803095401572">Alexander the Great</a> (356-323 BCE). His body was stored in honey in a coffin made of glass. Ordinary tourists were not allowed to visit it, but VIPs like Roman emperors were. Tourists might also have enjoyed the different vibe in Alexandria. According to the Greek orator <a href="https://www.britannica.com/biography/Dio-Chrysostom">Dio of Prusa</a> (c. 40-110/120 CE), the atmosphere in the coastal city was relaxed, with plenty of music, chariot racing and good food. <h2>Lazy summer days</h2> We can probably all relate to what the writer <a href="https://oxfordre.com/classics/display/10.1093/acrefore/9780199381135.001.0001/acrefore-9780199381135-e-5134">Pliny the Younger</a> (61/62-112 BCE) said about his summer break. Writing on a holiday in Tuscany, he <a href="https://www.loebclassics.com/view/pliny_younger-letters/1969/pb_LCL059.95.xml?rskey=Mdlmkl&result=1">said</a> he can only work “in the lazy way to be expected during a summer holiday”. Working any other way was simply not possible. Many of us will be able to relate to that!<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/243367/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/konstantine-panegyres-1528527">Konstantine Panegyres</a>, McKenzie Postdoctoral Fellow, researching Greco-Roman antiquity, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Dad sparks debate over "unfair" job ad

A recent job ad on Airtasker has highlighted just how far some parents are willing to go to reserve a public spot in the park. The job ad offered $50 for someone to sit at a picnic table in Alison Park in Randwick, Sydney for two hours on behalf of a family looking to host a birthday party. “Planning a kids’ birthday party at Alison Park. We need someone to mind the only picnic table in the park, so essentially, we need someone to sit at the table and reserve the spot for two hours from 7am to 9am,” the user wrote online, with detailed instructions of where to go. The post was shared in a parenting group on Facebook, where it received mixed reactions. “First come, first served,” one person commented. “It’s unfair, you can’t reserve public spaces,” added another. A few others thought $50 was too "cheap", but despite some backlash, most people were surprisingly supportive of the act. “Genius! An easy way to earn cash!” said one parent. “I don’t see any issue with this. It’s a great idea, and the guy is paying for it,” another mum wrote. Others pointed out that it was a good solution, with one writing: “I also don’t see an issue with this. It’s common practice for people to arrive early to reserve spots and tables at the park for parties. "Maybe this person doesn’t have any help, so it’s completely fine to pay someone to help them. Of course, it would be nicer if the council had a booking system, but they don’t." “I don’t think it’s a terrible idea. I actually prefer it when councils have a booking system for tables. It saves people from having to reserve a table all day for a 1pm party and holds them responsible for tidying up afterwards,” another added. The debate on reserving public spots is not new, with one family even resorting to using<a href="https://www.oversixty.com.au/travel/travel-trouble/council-cracks-down-on-odd-beach-trend" target="_blank" rel="noopener"> cling-wrap</a> to secure a gazebo at the beach.

"Un-Australian": Aussies called out over "selfish" summer habit

Australians have been called out for taking part in a "selfish" summer trend that has left many people fuming. The trend began as many erupted over the increase use of beach cabanas and "reserving" spaces on the sand, which then led to similar behaviour at campsites and carparks. Eager Aussies would set up a cabana or rope off a campsite and leave their belongings behind, only to return a matter of hours later and still have their spot reserved. One of Australia's leading etiquette experts, Jo Hayes, spoke to <a href="https://au.news.yahoo.com/aussies-called-out-over-selfish-summer-trend-taking-over-car-parks-and-campsites-un-australian-055035070.html" target="_blank" rel="noopener">Yahoo News</a> on the matter, and said the "poor" trend is "reflective of a general societal decline". She argued such acts are "bad form" and even branded them "un-Australian". It turns out the "reservations" aren't exclusive to beaches or campsites, as one woman was recently photographed standing in the middle of a car park at Balmoral Beach in Sydney, in a bid to deter others from seizing the spot, arguing her "husband was coming soon". Hayes said the "only people who have the right to do such reserving" are the local council/regulators in charge of that area, adding, "It's not fair." "There are ways that one can reserve the best, desired spots, that align with common decency and proper etiquette," Hayes said. "This is the way things were done in previous generations. Get to the venue early, claim your spot and set up your gear, then stay there — you must have at least one person staying with the claimed spot." "If you've taken the time to get there ahead of others — all power to you. Well done. But you don't have the right to lay down a blanket, or cordon off an area with your own self-made sign, and then choof off." Hayes said that when in doubt, apply the golden rule of thumb: Do unto others as you would have them do unto you. "The average Joe doesn't have the right to 'reserve' a spot and leave," she reiterated. "If a group wants to have an event at a council park, they can contact local council to officially reserve the spot. Council puts up a sign stating that the area is reserved for an event. One can't just put up their own sign." Image credits: Facebook

Despite decades of beach safety ads, at least 55 people have drowned in Australia this summer. It’s time to change tack

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/samuel-cornell-1418374">Samuel Cornell</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Australia is considered a nation of beach lovers. But with all this water surrounding us, drownings remain tragically common. At least <a href="https://www.royallifesaving.com.au/research-and-policy/drowning-research/summer-drowning-toll">55 people have drowned</a> in waterways in Australia so far this summer, most of whom drowned at the beach. And the season’s not over. Every drowning is a tragedy, and Australia is nowhere near the federal-government supported <a href="https://www.watersafety.com.au/australian-water-safety-strategy/">goal of zero drownings</a>. Public health agencies are <a href="https://www.news.com.au/breaking-news/australia-in-the-grip-of-a-disturbing-rise-in-summer-drownings/news-story/bf2b1595f36bb4b458b371b9fab4f7ed">concerned</a> about the drowning numbers. So how do we fix it? An important factor to consider is how beach safety messages are communicated. <h2>Another season, another campaign</h2> The peak water safety bodies in Australia, <a href="https://sls.com.au/">Surf Life Saving Australia</a> and <a href="https://www.royallifesaving.com.au/">Royal Life Saving Society – Australia</a>, work to reduce drownings in all Australian aquatic locations, from swimming pools to rivers to beaches. Their public safety campaigns aim to raise awareness of drowning and risks around the water. Australians are undoubtedly safer because of the work and advocacy of these organisations – but drowning numbers remain stubbornly high. Surf Life Saving Australia is running a new campaign this summer – <a href="https://sls.com.au/surf-life-saving-calls-in-hollywood-actor-angus-sampson-to-help-reach-men-at-high-risk-of-drowning/">Stop, Look, Stay Alive</a> – featuring Australian-born actor and filmmaker Angus Sampson. This campaign is one of many in recent years urging Australians to stay safe near the water. Others include: <ul> <li>the “swim between the flags” message</li> <li>the “<a href="https://sls.com.au/surf-life-saving-australia-launches-new-summer-safety-campaign-give-an-f-about-the-flags/">give an F about the flags</a>” campaign</li> <li>the <a href="https://sls.com.au/slsa-draws-the-line-on-rips/">“think line”</a> campaign, which urges people to “stop, look and have a plan”</li> <li>the <a href="https://www.floattosurvive.au/">“float to survive”</a> campaign, which urges people to <a href="https://static1.squarespace.com/static/5f7cf9fd8c3f251339c3dfa8/t/65ea851cbcbf287ede28cdc3/1709868332878/Float+to+Survive+Report.pdf">float if they’re in trouble in the water or stuck in a rip</a></li> <li>the <a href="https://www.royallifesaving.com.au/about/campaigns-and-programs/respect-the-river">“respect the river”</a> campaign.</li> </ul> But the tragic number of drownings, particularly during summer, suggests not everyone is heeding the message. In fact, <a href="https://www.sciencedirect.com/science/article/abs/pii/S0278434322000760#:%7E:text=However%2C%20there%20is%20no%20evidence,and%20hazards%20to%20the%20public.">Australian researchers in 2022 found</a> no evidence to suggest beach drowning deaths in Australia have reduced over the long term. This, the researchers said: <blockquote> rais[es] questions regarding the effectiveness of existing strategies designed to communicate messages and information about beach safety and hazards to the public. </blockquote> <h2>Changing how we communicate</h2> <a href="https://sls.com.au/surf-life-saving-calls-in-hollywood-actor-angus-sampson-to-help-reach-men-at-high-risk-of-drowning/">According to Surf Life Saving Australia</a> the current Angus Sampson campaign aims to be: <blockquote> appealing to more Aussies, in particular men who continue to swim at unpatrolled locations and take unnecessary risks. </blockquote> As the <a href="https://sls.com.au/surf-life-saving-calls-in-hollywood-actor-angus-sampson-to-help-reach-men-at-high-risk-of-drowning/">organisation notes</a>, 86% of all drowning deaths on Australia’s coast last year were men. The campaign involves ads on television and online, as well as outdoor advertising. The decision to use a mix of platforms is wise. But the use of a TV and movie celebrity may not be effective. A <a href="https://archive.acrs.org.au/files/arsrpe/RS030057.pdf?utm">review looking at road safety campaigns</a>, for example, found limited evidence of celebrity effectiveness in improving safety outcomes. Could it be more effective to, for example, <a href="https://academic.oup.com/heapro/article/38/2/daad034/7143327">use a TikTok star</a> who is hugely popular among young males? Research suggests using the <a href="https://www.tandfonline.com/doi/full/10.1080/28355245.2024.2350155">right platform</a> and “<a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7501494">voices that matter</a>” offer benefits when delivering safety messages. This is in part due to the <a href="https://www.tandfonline.com/doi/full/10.1080/17524032.2023.2237693">emotional connection</a> people form with these social media stars, which can result in behaviour change. When asked for evidence to show the current public messaging campaigns are working, Surf Life Saving Australia (SLSA) told The Conversation: <blockquote> SLSA is committed to preventing drowning through holistic, evidence-based approaches, combining awareness programs like Stop Look Stay Alive with lifesaving services, in-person programs, and education. This summer alone, lifesavers have performed over <a href="https://sls.com.au/coastal-safety/sls-research/national-summer-coastal-drowning-data/">2,500 rescues and 700,000 preventative actions</a>. Despite population growth, <a href="https://www.sciencedirect.com/science/article/pii/S1326020023000961">coastal drowning has remained stable</a>. This summer, 32 coastal drownings have been reported, fewer than the <a href="https://sls.com.au/coastal-safety/sls-research/national-summer-coastal-drowning-data/">same period last year</a>. SLSA focuses on behaviour change through initiatives like beachpassport.org.au (with 21,000+ “passports” issued already!), and on-beach programs that have provided active community learning <a href="https://www.sciencedirect.com/science/article/pii/S2212420924007040">opportunities</a>. It’s too early to comment on the broader effectiveness of Stop Look Stay Alive, however preliminary campaign results show positive impact and an evaluation will be conducted by <a href="https://www.beachsafetyresearch.com/">UNSW Beach Safety Research Group</a> later this year. </blockquote> <h2>Rethinking ‘swim between the flags’</h2> Many current beach messaging approaches, <a href="https://sls.com.au/1281-reasons-swim-flags/">including “swim between the flags”</a>, compel people to fit into what the system wants. But many beaches <a href="https://theconversation.com/australian-beachgoers-are-told-to-always-swim-between-the-flags-but-what-if-there-arent-any-220043">don’t have flags</a>. And not everyone stops or looks for flags, signs, or even the conditions before they go into the water. And studies show while most domestic beachgoers know to swim between the flags, <a href="https://www.sciencedirect.com/science/article/abs/pii/S0278434322000760#:%7E:text=However%2C%20there%20is%20no%20evidence,and%20hazards%20to%20the%20public">many choose not to</a> because, for example, people are located closer to beaches without flags or lifeguard patrols. What’s more, research suggests overseas visitors to Australia do not always understand <a href="https://www.sciencedirect.com/science/article/abs/pii/S0925753522003058">what “swim between the flags” means</a> or terms often used on common beach safety <a href="https://www.sciencedirect.com/science/article/pii/S0925753523003089">signage</a> such as “shore dump” and “shore break”. One 2021 <a href="https://www.sciencedirect.com/science/article/pii/S0925753523003089">study</a> found 21% of international students perceived “always swim between the flags” to mean that beachgoers who don’t or can’t swim need to stay outside the flags. This shows that current strategies aren’t resonating with all beach users, and there’s a need to reassess beach safety messaging. <h2>Changing tack</h2> Other forms of public safety messaging should also be considered when trying to reduce drowning numbers in Australia. For example, <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/hpja.785">people who have been caught in rip</a> might be encouraged to tell their stories publicly. Research into other areas of <a href="https://journals.sagepub.com/doi/full/10.1177/10732748241237328">public health communication</a>, such as vaccines, suggest this can form the basis of an effective campaign. <a href="https://www.sciencedirect.com/science/article/abs/pii/S0278434322000760#:%7E:text=However%2C%20there%20is%20no%20evidence,and%20hazards%20to%20the%20public.">Research also suggests</a> teaching beachgoers about coastal science can improve beach safety behaviour. For example, people can be taught about how rip currents work, using images of dye released into the water. Crucially, consensus is needed on which <a href="https://www.jsams.org/article/S1440-2440(06)00231-3/abstract">key messages to prioritise</a>. Too much differing messaging <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8807320/?utm_source">may lead to message fatigue or confusion</a> about which message is most important to follow. Messaging on beach safety to date has surely prevented drowning. But the stubborn drowning toll highlights the need to evaluate what is not working.

Do natural fabrics really keep us cooler in summer? Here’s the science

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/nisa-salim-1442233">Nisa Salim</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> The Bureau of Meteorology has warned Australia is facing one of the <a href="https://www.abc.net.au/news/2024-10-12/australia-facing-one-of-hottest-summers-on-record-bom/104464014">hottest summers on record</a>. As the weather warms, many of us reach for light-coloured clothes in natural fabrics, such as cotton and linen. But why are natural fabrics like these so much better at keeping us cool when the weather is hot? Here’s what the science says. <h2>Natural fabrics and sweat: a match made in heaven</h2> In hot weather, we sweat. As sweat evaporates, it carries heat away, which helps cool the body down. In hot weather, then, we want clothes that help take moisture away from the body as efficiently as possible. Natural fabrics are made using fibres extracted from plant- or animal-based sources such as cotton, linen, hemp, wool and silk. The primary component of all plant-based fibres is cellulose. Animal-based fibres are made up of proteins such as keratin and silk fibroin. Cellulose molecules are rich in compounds called hydroxyl groups that attract water and moisture. In scientific terms, they are hydrophilic – they love water. So, clothing made of cotton and linen is highly hydrophilic. It tends to absorb moisture and disperse it across the fabric, allowing it to evaporate more easily. This takes the sweat away quickly, making it more comfortable and breathable and allowing us to stay cool in sweltering temperatures. One downside of the natural fabrics is they wrinkle quickly (some people, of course, like that look). And on a really hot, sweaty day, natural fabrics can get heavy and wet. Animal fibres are basically proteins, and their properties vary depending on the source. Wool has been bio-engineered over millions of years to be comfortable to wear. Wool fibres are hydrophilic on the inside and hydrophobic on the outside, meaning they’re both water resistant and good at wicking moisture away. On the other hand, silk fabrics are very good at helping regulate temperature; they keep us cool in hot weather and warm in cold weather. <h2>Synthetic fabrics: less wrinkly, more sweaty</h2> Synthetic fabrics, on the other hand, are lighter and tend to wrinkle less. Common synthetic fabrics (such as polyester, nylon and acrylic) are all made from petroleum-based chemicals. Most synthetic fibres are made of long chains of hydrogen and carbon atoms and do not contain the hydroxyl groups we discussed earlier. Such fibres are therefore hydrophobic – they hate water. This means the water can’t spread evenly across the fabric and evaporate easily. They trap sweat against the skin, making the clothes less breathable and comfortable when the weather is warm and humid. However, some synthetic fabrics used in certain types of active wear can wick sweat away from body. And some semi-synthetic fabrics such as rayon or tencel (which are made from wood pulp or cotton with synthetic fibres) are more breathable than other synthetic fabrics such as polyester or nylon. <h2>Fabric weave makes a difference, too</h2> The colour of the clothing is also a contributing factor to keep you cool during summer. Light colours reflect sunlight away from you and help to keep the body cooler. There is some evidence dark colours absorb the <a href="https://www.sciencedirect.com/science/article/pii/S2214157X23012054">sunlight and associated heat</a>, making the surface of the skin warmer than normal. Another factor affecting breathability and comfort of clothing is the way the fabrics are woven. Fabrics that are loosely woven (sometimes known as “open weave”) with thinner materials naturally have more airflow, which helps you keep cool. For a quick, non-scientific test, hold a fabric up and see how much light passes through it. The more light you can see, the more breathable it likely is. The way the fabric is treated can play a role, too; such as for softening and wrinkle resistance. Using a fabric softener when you do a load of laundry usually doesn’t affect fabric breathability; softeners modify the surface of the fabric but don’t change the internal structure or porous nature of the fabrics. Wrinkle resistance is the ability of the fabric to stay smooth and polished even after washing. Synthetic fabrics are inherently wrinkle resistant. Natural fibres are more prone to wrinkles but can be chemically treated on the fabric surface during manufacturing to make them wrinkle resistant. Such treatments, however, may form layers on top of the fabric blocking the airflow, leading them to be less breathable.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/240909/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/nisa-salim-1442233">Nisa Salim</a>, Senior Lecturer at the School of Engineering, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Ash Barty loses high-profile Optus job

Ash Barty has lost her job as Optus' Chief of inspiration. The Grand Slam tennis champion signed on with the telecommunications company as one of their ambassadors in September 2022, just months after announcing her retirement from tennis. “The decision was taken as we looked to rebuild customer trust and focus on the fundamentals that we know are important to them – a resilient network, great value products and services, and simple, efficient customer service,” an Optus spokesperson told the Australian Financial Review. The telecommunications giant quietly made the move this year, and also parted ways with ex-F1 star Daniel Ricciardo, who was their Chief of Optimism. The role included fronting several campaigns for the brand and featuring in viral stunts. Both stars have updated their LinkedIn accounts to reflect their departure from the jobs. Barty had the role for two years, while Ricciardo was appointed as the Chief of Optimism in September 2020. The Australian Financial Review’s Myriam Robin described Optus’ move as a “one-two kick in the guts for Daniel”, who was cut by Red Bull’s junior team VCARB earlier this year. Optus' move away from Barty and Ricciardo comes after the company's former chief executive Kelly Bayer Rosmarin was replaced by Stephen Rue in September. While Barty lost her job at the telecommunications company, she is still listed as the Women's Tennis Association's National Indigenous Tennis Ambassador on LinkedIn. Since her retirement from tennis at the peak of her career, she has worked as a commentator for Stan during the Paris Olympics, released a series of children's books as part of her Little Ash series, and a tennis-themed book for kids called Tennis Camp Diaries.

Booking a summer holiday deal? Beware ‘drip pricing’ and other tactics to make you pay more than you planned

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/jeannie-marie-paterson-6367">Jeannie Marie Paterson</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Have you ever spotted what looked like a great deal on a website, added it to your “basket” and proceeded to checkout – only to find extra fees added on at the last minute? It’s frustratingly common when making airline, hotel and many other kinds of bookings to see an advertised price get ratcheted up at checkout with additional fees – perhaps “shipping insurance”, “resort fees” or just “taxes”. The practice is known as “<a href="https://www.accc.gov.au/consumers/pricing/price-displays">drip pricing</a>” and it can <a href="https://www.whitehouse.gov/wp-content/uploads/2023/03/WH-Junk-Fees-Guide-for-States.pdf">distort</a> consumer decision-making and affect competition. Nonetheless, there is no specific ban on this conduct in Australia. Some companies have, however, effectively been prosecuted for it under the Australian Consumer Law, which contains some strict rules about misleading consumers through advertising. Many of us have already begun booking flights, hotels and more as we head into the summer holiday season. Here’s what the law says about companies changing prices in the lead-up to checkout, and how you can protect yourself as a consumer. <h2>What’s wrong with drip pricing?</h2> The tactic that underpins drip pricing is to draw a customer in with an attractive “headline” price but then add in other fees as the customer approaches the checkout. It’s reasonable to ask whether there’s anything wrong with this practice: after all, the customer still sees the final price at checkout. Why might that be seen as misleading conduct under Australian Consumer Law? The reasons lie in views about consumer buying behaviour and the nature of the statutory prohibition. Typically, the closer a consumer gets to a sale, the less likely they are to pull out or even fully notice any additional fees. They may then end up paying more than they intended and also have lost the opportunity to deal with other suppliers of the same product at a better price. In the relevant section of Australian Consumer Law, there’s no requirement of an intention to mislead. It’s also not necessarily relevant that the true pricing situation is eventually revealed to the consumer or that it’s in the “fine print”. Thus, in the eyes of the law, it can be enough that consumers were enticed by an attractive headline price. <h2>Price surprises</h2> This legal position is well illustrated by a <a href="https://www8.austlii.edu.au/cgi-bin/viewdoc/au/cases/cth/HCA/2013/54.html">case</a> settled by the High Court in 2013, after the Australian Competition and Consumer Commission (ACCC) took on telecom provider TPG Internet in <a href="https://www.mondaq.com/australia/advertising-marketing-branding/282802/advertising-and-the-acl-fine-print-couldnt-save-tpg-internet-in-the-high-court">2010</a>, alleging misleading conduct. In this case, TPG had been advertising broadband internet services for $29.99 per month. But on reading the fine print, you’d have discovered this deal was only available with a landline service costing an additional $30 per month. The case moved up through Australia’s court system, but ultimately, the High Court majority held that the telco had engaged in misleading conduct. The High Court recognised that the very point of advertising is to draw consumers into “the marketing web”. It is therefore not enough to disclose the true (higher) price only at the point the transaction is concluded. TPG was fined $2 million in this case. Since then, the maximum penalties have increased, now the higher of: <ul> <li>$50 million</li> <li>three times the value obtained from the contravention, or (if the benefit can not be determined)</li> <li>30% of the business’s adjusted turnover during the breach period.</li> </ul> <h2>Dynamic pricing</h2> Other pricing complaints have been in the news recently, including concerns about point-of-sale dynamic pricing. Basically, this means using an algorithm that adjusts ticket prices in response to demand, as consumers wait in a virtual purchasing queue. Recent media reporting has centred on <a href="https://www.abc.net.au/news/2024-10-14/ticketmaster-live-nation-dynamic-pricing-tickets-class-action/104469646">concerns</a> about the use of point-of-sale dynamic pricing in the events ticketing industry. A form of dynamic pricing is used by hotels and airlines. They increase prices seasonally and according to demand. But these “dynamic” prices are clearly visible to consumers as they start looking for a deal. Some bodies even publish helpful tables of likely prices at different times. The kind of dynamic pricing that happens at the very point consumers are waiting to buy is very different and arguably creates an “unfair surprise”. Whether these kinds of practices also fall within the category of misleading conduct remains to be seen. But it is arguable that consumers could reasonably expect the real-time movement of prices to be disclosed upfront. Earlier this year, the government announced <a href="https://theconversation.com/albanese-government-promises-to-ban-dodgy-trading-practices-234142">plans</a> to address both drip pricing and dynamic pricing as part of a broader ban on unfair trading practices. <h2>What can consumers do?</h2> While all this law reform and litigation is playing out, here are some things you can do to avoid pricing shock. 1. Slow down. One of the strategies that online markets often rely on is “<a href="https://www.theguardian.com/australia-news/2024/oct/12/accc-suing-coles-woolworths-pricing-strategies-allegations">scarcity signalling</a>” – those clocks or numbers you see counting down as you move through a website. The very purpose of these is to make a consumer rush – which can mean failing to notice those additional fees that may make the buy not a good deal. 2. Take screen shots as you progress. Remember what it is you thought you were getting. Doing this also provides a basis for lodging a complaint if the headline and actual price don’t match up. 3. Check. Take a close look at the final bill before pressing pay. 4. Report. Tell your local Fair Trading Office or the ACCC if the advertised deal and the final price don’t meet up. A recent action taken by the ACCC against <a href="https://www.theguardian.com/australia-news/2024/sep/23/accc-suing-coles-woolworths-discounts-misleading">Woolworths and Coles</a> alleging “illusory” discounts was launched because of consumer tip-offs.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/244825/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/jeannie-marie-paterson-6367">Jeannie Marie Paterson</a>, Professor of Law, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Ant stings can be painful. Here’s how to avoid getting stung this summer (and what to do if you do)

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/sam-robinson-2237268">Sam Robinson</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> With the start of summer just days away, many of us will be looking forward to long sunny days spent at the beach, by the pool, out camping or picnicking in the park. Insects also love summer. This is when most of them <a href="https://www.australiangeographic.com.au/topics/science-environment/2016/12/experts-predict-increased-insect-activity-this-summer/">breed and feed</a>. But this shared appreciation of the season can sometimes lead to conflict. Insects have long been prey to many species, including birds, mammals, amphibians and other insects. As such, they’ve evolved a diverse range of defences – perhaps none more familiar to humans than the sting. Many ants have a sting at their rear end which they use to deliver venom. It’s not the sting itself that causes pain, but rather <a href="https://www.nature.com/articles/s41467-023-38839-1">the venom</a>. Ant venom contains a cocktail of different chemicals, some of which have evolved specifically to manipulate nerve endings in our skin to cause pain. Let’s look at some of the different ant stings you might experience this summer in Australia, and how to respond. <h2>Bull ants</h2> Bull ants (also known as bulldog ants, jumper ants, or jack jumpers) are large, for an ant. Some species can reach a length of <a href="https://en.wikipedia.org/wiki/Myrmecia_(ant)#:%7E:text=Each%20of%20their%20eyes%20contains,mm%20(1.5%20in)%3B%20M.">4 centimetres</a>. They are easily recognisable with their large eyes, long mandibles (jaws) and aggressive nature. Their sting is immediate, hot, sharp, and unmistakable, not dissimilar to that of a honeybee. The intense pain will last only a few minutes, before it’s replaced by some redness and swelling around the sting site. <h2>Green-head ants</h2> Green-head ants are also called green ants (but not to be confused with the <a href="https://en.wikipedia.org/wiki/Oecophylla_smaragdina">green tree ants</a> of northern Australia which do not sting). Green-head ants are common, and love our grass lawns. At around <a href="https://en.wikipedia.org/wiki/Green-head_ant">6 millimetres long</a>, they are significantly smaller than bull ants. They can be recognised by their shiny green and purple exoskeleton. Green-head ants tend to be less aggressive than bull ants, but they can still deliver a meaningful sting. The pain of a green-head ant’s sting can build more gradually, and create an intense, sticky ache. <h2>Fire ants</h2> Fire ants (or red imported fire ants) are originally from South America. They were first detected <a href="https://www.fireants.org.au/stop/how-fire-ants-arrived-in-australia">in Brisbane in 2001</a>, thought to have hitched a ride in shipping containers, and have since spread across south-east Queensland. Fire ants are reddish-brown and black and range in size from <a href="https://www.fireants.org.au/look/appearance">2–6 millimetres long</a>. You’re most likely to encounter fire ants at their nests, which look like a pile of powdery soil. A fire ant nest doesn’t have an obvious entry, which is a good way to distinguish them from other similar ant nests. Disturbing a fire ant nest will awaken an angry mass of hundreds of ants and put you at risk of being stung. The initial pain from an individual sting is like an intense, hot itch, though manageable. But fire ant stings rarely occur in single digits. One ant can sting multiple times, and multiple ants can sting one person, which can lead to <a href="https://theconversation.com/fire-ants-are-on-the-march-heres-what-happens-when-they-sting-218908">hundreds of stings</a>. Fire ant stings can lead to pus-filled ulcers and scarring in the days afterwards. If you live in an area where there are fire ants, it’s worth taking a few minutes to educate yourself on how to <a href="https://www.fireants.org.au/look">recognise and report</a> them. <h2>Electric ants</h2> <a href="https://www.antwiki.org/wiki/Wasmannia_auropunctata">Electric ants</a> are another nasty accidental import, originally from Central and South America. Currently restricted to <a href="https://www.outbreak.gov.au/current-outbreaks/electric-ants">Cairns and surrounds</a>, these are tiny (1.5 millimetres long) yellow ants. Like fire ants, these ants will typically defend en masse, so many will sting at once. Their sting is more painful than you’d expect from such a tiny creature. I liken it to being showered in red hot sparks. If you think you see electric ants, you should report this to <a href="https://www.business.qld.gov.au/industries/farms-fishing-forestry/agriculture/biosecurity/animals/invasive/restricted/electric-ant">Biosecurity Queensland</a>. <h2>Aussie ants aren’t the worst</h2> You might be surprised to hear Australian ants don’t even make the podium for the most painful ant stings. Among the prize winners are <a href="https://www.press.jhu.edu/books/title/10878/sting-wild">harvester ants</a> (North and South America) which cause an extreme, sticky ache, likened to a drill slowly turning in your muscle – for as long as 12 hours. The gold medal goes to the sting of the bullet ant of South and Central America, which <a href="https://www.press.jhu.edu/books/title/10878/sting-wild">has been described</a> as: <blockquote> Pure, intense, brilliant pain. Like walking over flaming charcoal with a 3-inch nail embedded in your heel. </blockquote> <h2>How to avoid getting stung (and what to do if you do)</h2> Fortunately, the solution is usually very simple. Look before you sit on the ground or lay out your picnic blanket, avoiding areas where you see ant nests or lots of foraging ants. Choice of footwear can also be important. In my experience, perhaps unsurprisingly, most stings occur on thong-wearing feet. If you do get stung, in most cases it’s going to get better on its own. Pain will usually subside after a few minutes (sometimes a little longer for a green-head ant sting). The redness, swelling and itch that typically follow can last for a few days. In the meantime, if needed, <a href="https://www.healthdirect.gov.au/insect-bites-and-stings">an ice pack</a> will help with the pain. If it’s particularly bad, a local anaesthetic cream containing lidocaine may offer some temporary relief. You can get this over the counter at the pharmacy. A small proportion of people may have an allergic reaction to ant stings. In very severe cases this might involve <a href="https://www.healthdirect.gov.au/insect-bites-and-stings#anaphylaxis">trouble breathing</a> or swallowing. If you or someone you’re with experiences these symptoms after an ant sting, seek urgent medical attention.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/241582/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/sam-robinson-2237268">Sam Robinson</a>, Senior Research Fellow, Institute for Molecular Bioscience, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What causes the itch in mozzie bites? And why do some people get such a bad reaction?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/cameron-webb-6736">Cameron Webb</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Are you one of these people who loathes spending time outdoors at dusk as the weather warms and mosquitoes start biting? Female mosquitoes <a href="https://www.annualreviews.org/content/journals/10.1146/annurev-ento-120811-153618">need blood</a> to develop their eggs. Even though they take a tiny amount of our blood, they can leave us with itchy red lumps that can last days. And sometimes something worse. So why does our body react and itch after being bitten by a mosquito? And why are some people more affected than others? <h2>What happens when a mosquito bites?</h2> Mosquitoes are attracted to warm blooded animals, including us. They’re attracted to the <a href="https://www.cambridge.org/core/journals/bulletin-of-entomological-research/article/abs/role-of-carbon-dioxide-in-hostfinding-by-mosquitoes-diptera-culicidae-a-review/2506B86EF63852B2D02EC3FCEE1E3B8B">carbon dioxide</a> we exhale, our body temperatures and, most importantly, <a href="https://www.abc.net.au/news/2024-11-08/mosquitoes-climate-change-skin/104548122">the smell of our skin</a>. The <a href="https://www.cell.com/trends/parasitology/abstract/S1471-4922(21)00237-3">chemical cocktail</a> of odours from bacteria and sweat on our skin <a href="https://www.cell.com/current-biology/fulltext/S0960-9822(23)00532-8">sends out a signal</a> to hungry mosquitoes. <a href="https://www.sciencedirect.com/science/article/pii/S2667114X21000522">Some people’s</a> skin smells more appealing to mosquitoes, and they’re more likely to be bitten than others. Once the mosquito has made its way to your skin, things get a little gross. The mosquito pierces your skin with their “proboscis”, their feeding mouth part. But the proboscis isn’t a single, straight, needle-like tube. There are multiple tubes, <a href="https://www.npr.org/sections/health-shots/2016/06/07/480653821/watch-mosquitoes-use-6-needles-to-suck-your-blood">some designed</a> for sucking and some for spitting. Once their mouth parts have been inserted into your skin, the mosquito will inject some saliva. This contains a mix of chemicals that gets the blood flowing better. There has even been a suggestion that future medicines could be inspired by the <a href="https://www.sydney.edu.au/news-opinion/news/2018/03/29/mosquito-saliva-vital-to-the-discovery-of-future-drugs.html">anti-blood clotting properties</a> of mosquito saliva. It’s not the stabbing of our skin by the mosquito’s mouth parts that hurts, it’s the mozzie spit our bodies don’t like. <h2>Are some people allergic to mosquito spit?</h2> Once a mosquito has injected their saliva into our skin, a variety of reactions can follow. For the lucky few, nothing much happens at all. For most people, and irrespective of the type of mosquito biting, <a href="https://www.frontiersin.org/journals/immunology/articles/10.3389/fimmu.2022.1024559/full">there is some kind of reaction</a>. Typically there is <a href="https://www.sciencedirect.com/science/article/abs/pii/S0161589023002304?via%3Dihub">redness and swelling of the skin</a> that appears within a few hours, but often more quickly, after just a few minutes. Occasionally, the reaction can cause pain or discomfort. Then comes the <a href="https://www.abc.net.au/news/health/2023-01-20/mosquito-bites-itchy-calamine-heat-ice-antihistamine-toothpaste/101652608">itchiness</a>. Some people do suffer severe reactions to mosquito bites. It’s a condition often referred to as “<a href="https://www.webmd.com/allergies/what-is-skeeter-syndrome">skeeter syndrome</a>” and is an allergic reaction caused by the protein in the mosquito’s saliva. This can cause large areas of swelling, blistering and fever. The chemistry of mosquito spit hasn’t really been well studied. But it has been shown that, for those who do suffer allergic reactions to their bites, the <a href="https://www.sciencedirect.com/science/article/abs/pii/S0091674904022183">reactions may differ</a> depending on the type of mosquito biting. We all probably get more tolerant of mosquito bites as we get older. Young children are certainly more likely to suffer more following mosquito bites. But as we get older, the reactions are less severe and may pass quickly without too much notice. <h2>How best to treat the bites?</h2> Research into treating bites <a href="https://linkinghub.elsevier.com/retrieve/pii/S0161589023002304">has yet to provide</a> a single easy solution. There are many <a href="https://www.healthline.com/health/outdoor-health/home-remedies-for-mosquito-bites">myths and home remedies</a> about what works. But there is little scientific evidence supporting their use. The best way to treat mosquito bites is by applying a cold pack to reduce swelling and to keep the skin clean to avoid any secondary infections. Antiseptic creams and lotions may also help. There is some evidence that <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10309056/">heat may alleviate</a> some of the discomfort. It’s particularly tough to keep young children from scratching at the bite and breaking the skin. This can form a nasty scab that may end up being worse than the bite itself. Applying an anti-itch cream may help. If the reactions are severe, <a href="https://www.healthdirect.gov.au/insect-bites-and-stings">antihistamine medications</a> may be required. <h2>To save the scratching, stop the bites</h2> Of course, it’s better not to be bitten by mosquitoes in the first place. Topical <a href="https://theconversation.com/insect-repellents-work-but-there-are-other-ways-to-beat-mosquitoes-without-getting-sticky-171805">insect repellents</a> are a safe, effective and affordable way to reduce mosquito bites. Covering up with loose fitted long sleeved shirts, long pants and covered shoes also provides a physical barrier. <a href="https://theconversation.com/are-mosquito-coils-good-or-bad-for-our-health-88548">Mosquito coils and other devices</a> can also assist, but should not be entirely relied on to stop bites. There’s another important reason to avoid mosquito bites: millions of people around the world suffer from mosquito-borne diseases. More than <a href="https://www.who.int/news-room/fact-sheets/detail/malaria">half a million people die</a> from malaria each year. In Australia, <a href="https://journals.plos.org/plospathogens/article?id=10.1371/journal.ppat.1005070">Ross River virus</a> infects more than 5,000 people every year. And in recent years, there have been cases of serious illnesses caused by <a href="https://www.science.org/content/article/how-rains-pigs-and-waterbirds-fueled-shocking-disease-outbreak-australia">Japanese encephalitis</a> and <a href="https://www.frontiersin.org/journals/public-health/articles/10.3389/fpubh.2023.1256149/full">Murray Valley encephalitis</a> viruses. <a href="https://theconversation.com/profiles/cameron-webb-6736">Cameron Webb</a>, Clinical Associate Professor and Principal Hospital Scientist, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Don’t like drinking plain water? 10 healthy ideas for staying hydrated this summer

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Have you heard the saying “water is life?” Well, it’s true. Water is an <a href="https://www.hsph.harvard.edu/nutritionsource/water/">essential nutrient</a>. Our body cannot produce sufficient water to live, so we need to consume water through food and fluids to survive. Maintaining hydration is one of the most fundamental components of good health. But lots of people don’t like drinking plain water much. The good news is there are many other healthy ways to help you stay hydrated. <h2>Why hydration is important</h2> Water is vital for many aspects of body functioning. About half our blood is “blood plasma”, which is over 90% water. Blood plasma is essential for carrying energy, nutrients and oxygen to the cells in the body that need it most. Water helps to remove waste products via the kidneys. It also helps keep joints lubricated, the digestive system functioning, the body’s temperature controlled and skin plump and strong. If you don’t consume enough water, you may experience symptoms of dehydration such as headaches, dizziness, tiredness, low concentration, constipation and a dry mouth. Being severely dehydrated increases the risk of <a href="https://www.kidney.org/atoz/content/kidneystones">kidney stones</a> and <a href="https://www.healthdirect.gov.au/urinary-tract-infection-uti">urinary tract infections</a>. If you feel thirsty, it means your body is already <a href="https://my.clevelandclinic.org/health/treatments/9013-dehydration#:%7E:text=If%20you're%20thirsty%2C%20you,life%2Dthreatening%20illnesses%20like%20heatstroke.">mildly dehydrated</a>, so make sure you pay attention to what your body is telling you. <h2>How much fluid do you need?</h2> The amount of fluid we need changes as we age. Relative to our body weight, our needs decrease. So, a newborn baby has higher fluid needs (per kilogram body weight) than their parent, and older adults have lower fluid needs than younger adults. Fluid requirements are related to metabolic needs and vary from person-to-person. The normal turnover of water in adults is approximately 4% of total body weight per day. So, for example, if you weigh 70 kilograms, you’ll lose about 2.5 to 3 litres of water a day (not including sweating). This means you will need to consume that amount of water from food and drinks to maintain your hydration. Eight cups (or two litres) a day is often <a href="https://www.npr.org/2022/09/21/1124371309/busting-common-hydration-water-myths?utm_source=npr_newsletter&utm_medium=email&utm_content=20221016&utm_term=7386723&utm_campaign=health&utm_id=31926817&orgid=&utm_att1=">mentioned</a> as the amount of water we should aim for and a nice way to track your intake. But it doesn’t account for individual variation based on age, gender, body size and activity levels. Alcohol is a diuretic, which means it dehydrates the body by promoting water loss through urine. This fluid loss is a key factor that contributes to the severity of a hangover. Always have a glass of water in between alcoholic drinks to help stay hydrated. Caffeinated drinks (like tea and coffee) only have a mild diuretic effect. For most healthy adults, it’s okay to consume up to 400 mg of caffeine a day – that’s about four cups of coffee or eight cups of tea. If you drink more than this, it may impact your hydration levels. To check your specific requirements, check out the Australian <a href="https://www.nrv.gov.au/nutrients/water">guidelines</a> for fluid intake. <h2>People who should take extra care</h2> Some people are at greater risk of the harmful health effects from dehydration and need to pay special attention to their fluid intake. The highest priority groups are babies, young kids, pregnant women, and older adults. These groups are at greater risk for many reasons, including relatively higher water needs per kilo of body weight, reduced ability to detect and respond to symptoms of dehydration, and barriers to consuming fluids regularly. Family and friends can play an important role in <a href="https://www.agedcareguide.com.au/information/hydration-for-elderly-people-and-the-dangers-of-dehydration">supporting loved ones</a> to maintain hydration, especially during warm weather. <h2>Ten ideas for keeping fluids up this summer</h2> <ol> <li> Download a water reminder app on your phone This will help keep you on track during the day and give you digital “high fives” when you hit your water goals. </li> <li> Add sugar-free flavouring Try a sugar-free fruit infusion in your water to make it more appealing. Prepare a jug in the refrigerator and infuse it overnight so it’s chilled for you the next day. Fill it up and take it everywhere with you! </li> <li> Add some fresh fruit Add some slices of lime, lemon, berries, pineapple or orange to your water bottle for some natural flavouring. If the bottle is kept in a fridge, the fruit will stay fresh for about three days. </li> <li> Make a jug of iced tea (not the bottled stuff) There are many great sugar-free recipes online. Tea contributes to fluid intake too. For green and black teas, brew in boiling water then cool overnight on the bench before refrigerating. Fruit teas can be made using cold water immediately. </li> <li> Add a dash of cordial to your water A small amount of cordial in your water is a healthier alternative to drinking a sugar-sweetened soft drink or fruit juice. Diet cordials have less added sugar again. </li> <li> Make a fruit ‘slushie’ Combine fresh fruit, ice and water at home in the morning and sip to increase your fluid intake for the day. </li> <li> Buy a soda maker for your home Some people find plain water tastes better with bubbles. Sparkling mineral water is great too, as long as there is no added sugar or sweeteners. </li> <li> Before you eat anything, have a glass of water Make it a rule with yourself to have a glass of water before every snack or meal. </li> <li> Eat water-rich fruits and vegetables Many fruits and vegetables have a high water content. Some of the best include berries, oranges, grapes, carrots, lettuce, cabbage, spinach and melons. Keep a container full of cut-up fruit to snack on in your fridge. </li> <li> Use a water bottle Take it with you during the day and keep it by your bed overnight. </li> </ol> <h2>A tip on water bottles</h2> Water bottles are everywhere and sometimes seem to offer <a href="https://www.refinery29.com/en-au/emotional-support-water-bottle-girlies-tiktok-trend">emotional support</a> as well as hydration. Having a water bottle you enjoy using can go a long way in helping you keep up your fluids during the day. Pay attention to the material of the water bottle and use one that helps you form good habits. Some people prefer metal water bottles as they can keep water cooler for longer (others feel like they are camping). Some prefer glass bottles because the water isn’t affected by any flavours from the container (others fear breaking the glass). Consider the practical aspects, too: Will it fit in your bag? Will it be light enough to carry with you? Can you “chug” on it when you’re exceptionally thirsty? Does the lid require screwing? How durable is it in preventing leaks? Do some <a href="https://www.marthastewart.com/7842071/best-water-bottles-hydration">homework</a> on your water bottle, an essential accessory! <a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, Professor of Community Health and Wellbeing, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, Dietitian and Researcher, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How to buy a good pair of sunglasses

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/jacobo-garcia-queiruga-1496353">Jacobo García Queiruga</a>, <a href="https://theconversation.com/institutions/universidade-de-santiago-de-compostela-2533">Universidade de Santiago de Compostela</a> and <a href="https://theconversation.com/profiles/veronica-noya-padin-1529488">Verónica Noya Padín</a>, <a href="https://theconversation.com/institutions/universidade-de-santiago-de-compostela-2533">Universidade de Santiago de Compostela</a> Nowadays you can buy a cheap pair of sunglasses just about anywhere – from supermarkets and petrol stations to corner shops and online fashion retailers, but such ubiquity may prompt doubts as to the protection they can offer. While their lenses usually meet certain minimum UV protection requirements, their quality in other respects, such as visual clarity, is dismal. Opticians, however, are governed by national health regulations, meaning that they have to meet higher standards such as the <a href="https://single-market-economy.ec.europa.eu/single-market/ce-marking_en">CE</a> and <a href="https://www.gov.uk/guidance/using-the-ukca-marking">UKCA</a> marks. Professional opticians are therefore much better equipped to help customers find sunglasses that not only meet their practical demands, but which are also comfortable and well suited to their facial features. <h2>Rules for protection</h2> <a href="https://www.iso.org/obp/ui/en/#iso:std:iso:12312:-1:ed-2:v1:en">European law</a> classifies sunglass lenses as “personal protective equipment”, outlining five levels of protection. Category 0 lenses allow 80-100% of light through, while those in category 4 only let 3-8% through, meaning they are not suitable for driving. Category 3 is the most commonly used, as they are appropriate for most situations, including driving. So, do darker lenses protect you better? The short answer is: not necessarily. The degree of light absorption depends on how and where they will be used: category 4 lenses are designed for extremely bright areas like high mountains or deserts, but may actually reduce your visibility in other situations. However, all sunglasses that meet the established standards will protect your eyes from UV radiation. <h2>Quality of vision</h2> Wearing sunglasses can give the feeling that your vision is impeded. This is because a tinted lens selectively filters light: it lets in one type of radiation and limits another. Three concepts can help us understand how this works, and why it matters. First up is visual acuity. This is the term used to measure how “sharply” we see, and it is tested by asking patients to read increasingly small letters that appear on a screen or wall chart, with an ideal result around 100%. However, this test is performed with black letters on a well lit white background, so it does not take into account how visual quality may vary in other lighting conditions. Contrast sensitivity is defined as the ability to differentiate objects from the surrounding background. It is, for instance, more difficult to distinguish black letters on grey backgrounds than on white backgrounds. Lastly, we have refractive errors, which affect both visual acuity and contrast sensitivity. These are what cause astigmatisms and make us long or short sighted. Wearing non-prescription sunglasses when suffering from any of these conditions can make vision even worse than it would be without them. <h2>Colour matters</h2> With all this in mind, we should also address the common question of lens colour. While colour does not affect protection, <a href="https://www.researchgate.net/publication/11320153_Effect_of_variable_tinted_spectacle_lenses_on_visual_performance_in_control_subjects">it can affect contrast and the feeling of brightness</a>, because each colour filters out a different wavelength of light. <a href="https://www.researchgate.net/publication/11320153_Effect_of_variable_tinted_spectacle_lenses_on_visual_performance_in_control_subjects">Grey lenses filter out all wavelengths of light</a>, while tints such as brown or green have a different effect on light absorption. This means that <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10699545/">visual perception</a> tends to be brighter through a brown lens, very dark through grey ones, and more natural through green ones. <h2>Plastic or glass lenses?</h2> Colour isn’t the only thing that affects quality of vision: we also have to pay attention to what the lenses are made of. While they are most commonly made of specialised plastics – known as organic lenses – you can also find glass ones, known as mineral lenses. These two materials are not the same. Organic lenses are lighter and stronger, while mineral lenses are more scratch resistant and are less prone to colour distortion. This means that mineral lenses offer greater quality of vision. <h2>What about polarised lenses?</h2> Polarised lenses block light that reaches the eye at a certain angle after reflecting off a surface such as a road or water, thus reducing glare. They are particularly suited to driving or spending time around water. However, they can be unsuitable in certain situations. For example, they block light from screens, making them appear darker or even completely black, meaning devices often have to be rotated to improve visibility. They are also not ideal for certain winter sports: by eliminating glare they make it very easy to miss icy patches on the ground. <h2>Other features</h2> Lastly, there are certain design features that we cannot overlook when choosing a pair of sunglasses. Gradient lenses are darker at the top, and graduate down to a lighter tint at the bottom – they usually absorb around 85% of light in their darkest area, and 10% in the lightest. These lenses are stylish, but that does not affect their protection against UV rays. That said, they might be better suited to cloudy conditions, and on a bright summer day they may not be the best option. Reflective lenses have a layer on their outer surface that reflects light and enhances protection. Unfortunately, this treatment is easily damaged or scratched. Lenses with anti reflective coating on the inside of the lens provide greater clarity of vision by eliminating light reflected from behind the wearer. This treatment is usually applied to large sunglasses, or glasses with optically very high quality lenses. In the event of any doubt, the best possible advice is to speak to your optician or optometrist to find the sunglasses that best meet your needs.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/229953/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/jacobo-garcia-queiruga-1496353">Jacobo García Queiruga</a>, Profesor Interino en el Área de Optometría (OD, MSc, PhD), <a href="https://theconversation.com/institutions/universidade-de-santiago-de-compostela-2533">Universidade de Santiago de Compostela</a> and <a href="https://theconversation.com/profiles/veronica-noya-padin-1529488">Verónica Noya Padín</a>, Investigadora predoctoral - Área de Optometría, <a href="https://theconversation.com/institutions/universidade-de-santiago-de-compostela-2533">Universidade de Santiago de Compostela</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Daylight savings is about to start. But why do the days get longer?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/laura-nicole-driessen-892965">Laura Nicole Driessen</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> The days are getting longer and in Australia, the switch to daylight saving time is almost upon us (for about 70% of the population, anyway). But why do we have longer days in summer and shorter days in winter? <h2>It’s all about the tilt</h2> Earth goes around the Sun in an almost circular orbit. But not everything is lined up perfectly. Earth’s axis is tilted by 23.44 degrees relative to its orbit around the Sun. Imagine Earth’s orbit as a flat frisbee with the Sun in the middle and Earth as a ball on a stick going around the edge. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/623235/original/file-20241003-16-xourdg.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/623235/original/file-20241003-16-xourdg.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/623235/original/file-20241003-16-xourdg.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=400&fit=crop&dpr=1 600w, https://images.theconversation.com/files/623235/original/file-20241003-16-xourdg.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=400&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/623235/original/file-20241003-16-xourdg.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=400&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/623235/original/file-20241003-16-xourdg.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=503&fit=crop&dpr=1 754w, https://images.theconversation.com/files/623235/original/file-20241003-16-xourdg.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=503&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/623235/original/file-20241003-16-xourdg.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=503&fit=crop&dpr=3 2262w" alt="Diagram of Earth's rotation around the sun." /></a><figcaption>Earth goes around the Sun in an almost circular orbit. <a class="source" href="https://www.shutterstock.com/image-vector/earths-orbit-earth-rotation-around-sun-2441275921">Angela Cini/Shutterstock</a></figcaption></figure> If Earth’s axis wasn’t tilted (if its tilt was zero degrees) the stick would be exactly perpendicular to the frisbee. If you grab that perpendicular stick and tip it 23.44 degrees sideways, that’s what Earth’s tilt looks like now. As Earth orbits the Sun, the tilt of the stick does not rotate relative to the Sun. If you were in outer space looking at the Sun and you watched from the exact same position for a whole year, you would see Earth go around the Sun while the stick stayed tilted the same direction. In other words, if the top of the stick was pointing to the right when you started watching Earth go around the Sun, it would stay pointing to the right the whole way around. This tilt gives us longer days in summer and shorter days in winter. Let’s set up the scenario so the Northern Hemisphere is the top of the planet and the Southern Hemisphere is the bottom of the planet. When Earth is on one side of the Sun, the top of the stick is pointed towards the Sun. This is summer in the Northern Hemisphere and winter in the Southern Hemisphere. Six months later, when Earth is on the other side of the Sun, the bottom of the stick is pointed towards the Sun – and the seasons are reversed. <h2>Solstices and equinoxes</h2> Those two points, when the top of the stick is pointing directly towards the Sun or directly away from the Sun, are the solstices. They are the longest and shortest days of the year, depending on your hemisphere. The shortest day of 2024 in Australia was June 21. Looking forward to sunnier times, the longest day of the year in 2024 will be December 21. In between the summer and winter solstice, we have the equinoxes – when days and nights are almost exactly the same length. Those are the days when the stick through Earth is “side-on” to the Sun. The equinox is also the day when the Sun passes directly over Earth’s equator. In 2024 this happened on March 20 at 2:06pm AEDT and September 22 at 10:43pm AEST. That means that since September 22, days have been getting longer than nights in the Southern Hemisphere. <h2>What does daylight savings do?</h2> Earth’s tilt means the Sun both rises earlier and sets later as we head towards summer. When the clocks (in some states) switch to daylight saving time, people in these states all get one hour less of sleep. However, the total length of the day doesn’t change just because we changed our clocks. For me, daylight savings means I need an extra cup of coffee in the morning for about a week before I adjust to the daylight savings-lag (like jet lag, but without the fun of travel). What it really gives us is more daylight in the evening, instead of more daylight in the morning. If you’re already a morning person, this isn’t the way to go. But if you prefer to have a long dinner in the summer sun it’s ideal. <h2>Has it always been this way?</h2> Earth’s axis hasn’t always been tilted at 23.44 degrees. It cycles from a minimum 22.1 degree tilt to a maximum 24.5 degree tilt and back again once every approximately 41,000 years. Earth’s axis also “precesses”, where the stick through it draws a circle once every approximately 26,000 years. You can see this in the animation below. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/622704/original/file-20241001-16-lh8pl9.gif?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/622704/original/file-20241001-16-lh8pl9.gif?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/622704/original/file-20241001-16-lh8pl9.gif?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=600&fit=crop&dpr=1 600w, https://images.theconversation.com/files/622704/original/file-20241001-16-lh8pl9.gif?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=600&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/622704/original/file-20241001-16-lh8pl9.gif?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=600&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/622704/original/file-20241001-16-lh8pl9.gif?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=754&fit=crop&dpr=1 754w, https://images.theconversation.com/files/622704/original/file-20241001-16-lh8pl9.gif?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=754&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/622704/original/file-20241001-16-lh8pl9.gif?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=754&fit=crop&dpr=3 2262w" alt="A gif of the Earth wobbling in a circle on its axis." /></a><figcaption>Demonstration of the precession of Earth’s axis. <a class="source" href="https://science.nasa.gov/resource/axial-precession-wobble/">NASA/JPL-Caltech</a></figcaption></figure> The length of a day on Earth hasn’t always been the same, either. At the moment, the length of a day is nearly exactly 24 hours. But it’s shifting all the time by tiny amounts. This is tracked very closely by a system of telescopes and satellites. These systems measure “<a href="https://ggos.org/item/earth-orientation-parameter/#:%7E:text=Accordingly%2C%20the%20EOP%20describe%20the,as%20tides%20and%20continental%20drift">Earth orientation parameters</a>” that describe Earth’s exact orientation compared to the position of stars in the sky. These are important to astronomers because the exact location of our telescopes is important for creating accurate maps of the sky. On top of all of this, the gravitational drag from the Moon causes days to become longer by around 2.3 milliseconds every 100 years. A few billion years ago, Earth’s day was a lot shorter – <a href="https://www.earthscope.org/news/a-day-is-not-always-24-hours-how-earths-shifting-systems-cause-day-length-variation/#:%7E:text=Billions%20of%20years%20ago%2C%20the,to%20the%20day%20every%20century">only 19 hours long</a>.

Air traffic controller found asleep on the job

An air traffic controller has been found asleep on the job, with the incident prompting calls for better fatigue management, according to Australia's transport watchdog. The report by the Australian Transport Safety Bureau (ATSB) dates back to December 2022, when the Airservices Australia controller was found lying across two chairs with a blanket covering them at 5am. The controller had worked multiple night shifts with reduced extended rest periods, "which likely reduced their ability to obtain restorative sleep", the report claimed. ATSB chief commissioner Angus Mitchell said the controller had increased their chances of falling asleep "by lying across two chairs, not moving, and not undertaking activities to maintain mental alertness". When a colleague discovered the snoozing worker, there was no traffic in the Cairns airspace they were responsible for managing, which was usual for that time of day, and there were no scheduled flights until after their shift. However, the report highlighted the possible problems the incident pay have caused, saying if the traffic controller was woken up by a radio broadcast, they may have experienced "sleep inertia", with the risk of delayed communications, or incorrect instructions or actions. "There were no negative consequences from this occurrence, but it does highlight areas for improvement in work scheduling and fatigue risk management," said Mitchell . Since the incident, Airservices Australia has increased its overall number of air traffic controllers, and has also drawn up new guidelines and training about fatigue risk assessment. "Fatigue remains one of the most relevant ongoing concerns for safe transport, despite increased awareness across the transport sector," said Mitchell. Image credits: Shutterstock

“Song of the summer”: Karl Stefanovic appears in wild 50th birthday music video

Karl Stefanovic has confused and delighted fans in equal measure with the release of a bizarre music video to celebrate his 50th birthday. The Today Show host teamed up with singer Keli Holiday, also known as one half of music duo Peking Duk, to star in a cover of Dolly Parton and Kenny Rogers’ 1983 classic Islands In The Stream. The newly formed duo performed the song with their silk shirts blowing in the wind in full 1980s music video style, showing off their chests. Holiday took to his Instagram on Wednesday to tease the musical team up, sharing screenshots from private messages in which Stefanovic reached out to say, "I'm prepared to do a duet with you". <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-permalink="https://www.instagram.com/reel/C_bqOAGhfTP/?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/C_bqOAGhfTP/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by keli holiday (@keliholiday)</a> </div> </blockquote> “I shared this sentiment online to see if the people shared that same yearning for a Keli-Karl duet and the response was an overwhelming ‘yes’.

The response to the video has been mostly positive, while some people couldn't contain their confusion. “This is so Australian, it should be used as a tourism advertisement,” reads one top-rated comment read. “Just dropped to my knees in Aldi,” commented one fellow Aussie musician, while another called it the "Song of the year." Another person commented, "What is going on?? I feel like I’ve just woken up from a bender at 3am with Rage playing hilariously bad 80’s videos…", while Karl's wife Jasmine added, "You need to wear eyeliner all the time now. Suits you!"

Tasmania to cover travel costs in exchange for these "odd jobs"

Tasmania has just opened applications for 10 "odd jobs" that you could do in exchange for a free trip to the state. As part of Tourism Tasmania's latest campaign to entice winter visitors, they are offering to cover travel and accommodation costs in exchange for a few odd jobs. While the work is unpaid and only lasts a day or two, the chosen Aussies will also get a hire car and a hamper worth up to $500 of local Tasmania produce and memorabilia. One of the jobs on offer is a wombat walker at East Coast Natureworld in Bicheno. The wildlife park is looking for an animal and nature lover, who loves going out for walks to lead the furry animals on their morning waddles as part of their rehabilitation program. Another job on offer is a “paranormal investigator” who will help Tasmania’s Most Haunted in New Norfolk capture and document any disturbances, spectral figures or unexplained phenomena at Willow Court Asylum. They are looking for someone who is “attuned into interactions with the otherworldly” and respects the controversial history of Willow Court. Other jobs include a “truffle snuffler” at The Truffledore, which involves truffle hunting with a canine companion, a “wine whisperer” at Clover Hill, a “puffer nut” at West Coast Wilderness Railway and “soaksmith” at Little Things Farm. They are also looking for an “oyster organiser”, a “star seeker” and “sauna stoker”. Anyone interested in taking these odd jobs must explain in 50 words or less why they want to swap their day job for the odd job in Tasmania. Applications are open from now until July 8 this year. The total value of the prize pool is up to $25,000. “More and more, we’re all looking for remedies through experience that make life feel simpler and less stressful," Tourism Tasmania chief marketing officer Lindene Cleary said. “Watching ‘cottagecore’ videos of people gardening and building cabins in the woods. Hobbies like cooking and reading are even trumping digital hobbies like gaming. "So, we extend a warm invite to Australians to apply for an odd job in Tasmania and wake up from their cool weather coma.” Images: Tourism Tasmania

Telstra announces thousands of job losses

Telstra is set to axe 2,800 jobs, or 9 percent of their total workforce, by the end of 2024 in a bid to save a whopping $350 million. The telco giant announced that the job cuts would "begin immediately" as a result of the impending business "reset" strategy. Chief executive officer Vicki Brady announced the cuts on Tuesday, and said the job cuts were "difficult" but "necessary" as parts of Telstra were not performing to the required levels. <div> <div>"We need to be a more efficient and sustainable business to ensure we can keep investing at the levels required to meet the ever-increasing demand for our connectivity and services for our customers right across the country," she said.</div> </div> Ms Brady also assured Telstra customers that the job losses would not affect customer service teams. “We have invested significantly in our customer service over recent years. That includes on-shoring our call centres for consumer and small business customers, it includes buying back our stores to deliver consistently good experience,” she said. “None of these changes impact those commitments." “As we work through the further changes still to come that I expect to be able to share with our employees in mid-July, customer service and experience will continue to be a key priority in that.” Despite Ms Brady's claims, Communication Workers Union (CWU) National Assistant Secretary, James Perkins, who represents Telstra workers said there was no way the substantial job cuts would not affect services. “While the detail of where exactly these jobs are being cut from is still unclear, one thing is certain – it will have a devastating impact on services,” Mr Perkins said. “You can’t slash thousands of jobs without seriously impacting the delivery of services across the country. Telstra has to answer to this.” The job cuts come as Telstra continues to scale up AI adoption, after the company announced in February it was expanding two in-house developed generative AI solutions following “promising pilots with frontline team members, enabling faster and more successful interactions with customers”.
