Matcha is having a moment. What are the health benefits of this green tea drink?

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/evangeline-mantzioris-153250">Evangeline Mantzioris</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>Matcha has experienced a surge in popularity in recent months, leading to reports of <a href="https://www.smh.com.au/goodfood/sydney-eating-out/global-matcha-shortage-hits-australia-as-skyrocketing-popularity-rivals-coffee-20241101-p5kn6v.html">global shortages</a> and price increases.</p> <p>If you haven’t been caught up in the craze, matcha is a powdered version of green tea. On a cafe menu you might see a hot or iced matcha latte, or even a matcha-flavoured cake or pastry. A quick google brings up <a href="https://www.foodandwine.com/tea/matcha-tea/matcha-recipes">countless recipes</a> incorporating matcha, both sweet and savoury.</p> <p>Retailers and cafe owners <a href="https://www.smh.com.au/goodfood/sydney-eating-out/global-matcha-shortage-hits-australia-as-skyrocketing-popularity-rivals-coffee-20241101-p5kn6v.html">have suggested</a> the main reasons for matcha’s popularity include its “instagrammable” looks and its purported health benefits.</p> <p>But what are the health benefits of matcha? Here’s what the evidence says.</p> <h2>First, what is matcha?</h2> <p><a href="https://www.mdpi.com/1420-3049/26/1/85">Matcha</a> is a finely ground powder of green tea leaves, which come from the plant <em>Camellia sinensis</em>. This is the same plant used to make green and black tea. However, the <a href="https://naokimatcha.com/blogs/articles/how-matcha-is-made-in-japan">production process</a> differentiates matcha from green and black tea.</p> <p>For matcha, the tea plant is grown in shade. Once the leaves are harvested, they’re steamed and dried and the stems are removed. Then the leaves are carefully ground at controlled temperatures to form the powder.</p> <p>The <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6571865/">production process</a> for green tea is simpler. The leaves are picked from the unshaded plants, heated and then dried. We then steep the dried leaves in hot water to get tea (whereas with matcha the whole leaf is consumed).</p> <p>With black tea, after the leaves are picked they’re exposed to air, which leads to oxidation. This makes the leaves black and gives the tea a different flavour.</p> <h2>A source of phytonutrients</h2> <p>Phytonutrients are <a href="https://theconversation.com/phytonutrients-can-boost-your-health-here-are-4-and-where-to-find-them-including-in-your-next-cup-of-coffee-132100">chemical compounds found in plants</a> which have a range of benefits for human health. Matcha contains several.</p> <p>Chlorophyll gives plants such as <em>Camellia sinensis</em> their green colour. There’s some evidence chlorophyll may have <a href="https://www.mdpi.com/2223-7747/12/7/1533">health benefits</a> – including anti-inflammatory, anti-cancer and anti-obesity effects – due to its antioxidant properties. Antioxidants neutralise free radicals, which are unstable molecules that harm our cells.</p> <p>Theanine has been shown to <a href="https://www.mdpi.com/2504-3900/91/1/32">improve sleep</a> and <a href="https://link.springer.com/article/10.1007/s11130-019-00771-5?crsi=662497574&amp;cicada_org_src=healthwebmagazine.com&amp;cicada_org_mdm=direct">reduce stress and anxiety</a>. The only <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/theanine">other known</a> dietary source of theanine is mushrooms.</p> <p>Caffeine is a phytonutrient we know well. Aside from increasing alertness, caffeine has also demonstrated <a href="https://www.tandfonline.com/doi/full/10.1080/10408398.2022.2074362?casa_token=ADALIs6M3iAAAAAA%3AXpY35se0zLddAEIbZAaeCcDaNWm94s2WJaDHfXDRvVZgYq_xTxsCFuvtrtNXMXAL9uNIvLlYzO30aA#abstract">antioxidant effects</a> and some protection against a range of chronic and neurodegenerative diseases. However, too much caffeine can have negative side effects.</p> <p>Interestingly, shading the plants while growing appears to <a href="https://scijournals.onlinelibrary.wiley.com/doi/pdfdirect/10.1002/jsfa.9112?casa_token=KxVD9i9p4BsAAAAA:OwGTauXFHAndyJkam8WuXrmGQ2k1kaSRu5pOqJOrhSyRSeWkDwdrI23qaD5WVH1HGqZLFdsjP9ZTvolw">change the nutritional composition</a> of the leaf and may lead to higher levels of these phytonutrients in matcha compared to green tea.</p> <p>Another compound worth mentioning is called catechins, of which there are several different types. Matcha powder similarly has <a href="https://theconversation.com/matcha-tea-what-the-current-evidence-says-about-its-health-benefits-202782">more catechins</a> than green tea. They are strong antioxidants, which <a href="https://link.springer.com/article/10.1186/s41702-020-0057-8">have been shown</a> to have protective effects against bacteria, viruses, allergies, inflammation and cancer. Catechins <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/catechin#:%7E:text=Catechin%20is%20naturally%20present%20in,containing%20many%20catechins%20%5B130%2C131%5D.">are also found</a> in apples, blueberries and strawberries.</p> <h2>What are the actual health benefits?</h2> <p>So we know matcha contains a variety of phytonutrients, but does this translate to noticeable health benefits?</p> <p>A review published in 2023 identified only <a href="https://www.sciencedirect.com/science/article/pii/S2665927122002180">five experimental studies</a> that have given matcha to people. These studies gave participants about 2–4g of matcha per day (equivalent to 1–2 teaspoons of matcha powder), compared to a placebo, as either a capsule, in tea or in foods. Matcha decreased stress and anxiety, and improved memory and cognitive function. There was no effect on mood.</p> <p>A <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0309287">more recent study</a> showed 2g of matcha in older people aged 60 to 85 improved sleep quality. However, in <a href="https://www.mdpi.com/2072-6643/16/17/2907">younger people</a> aged 27 to 64 in another study, matcha had little effect on sleep.</p> <p>A <a href="https://link.springer.com/article/10.1007/s11130-022-00998-9">study in people with obesity</a> found no difference in the weight loss observed between the matcha group and the control group. This study did not randomise participants, and people knew which group they had been placed in.</p> <p>It could be hypothesised that given you consume all of the leaf, and given levels of some phytonutrients may be higher due to the growing conditions, matcha may have more nutritional benefits than green tea. But to my knowledge there has been no direct comparison of health outcomes from green tea compared to matcha.</p> <h2>There’s lots of evidence for green tea</h2> <p>While to date a limited number of studies have looked at matcha, and none compared matcha and green tea, there’s quite a bit of research on the health benefits of drinking green tea.</p> <p>A <a href="https://www.sciencedirect.com/science/article/pii/S0944711317300867?casa_token=dpbAEQQ7Is4AAAAA:U6aggqZM_G0KJ8hkhx0TGSvQywr4utlgKzwUnUj9x5t9eWd-FKENjbTvUv6s4TBTaPYrob-qQkk">systematic review of 21 studies</a> on green tea has shown similar benefits to matcha for improvements in memory, plus evidence for mood improvement.</p> <p>There’s also evidence green tea provides other health benefits. Systematic reviews have shown green tea leads to <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/ptr.6697?casa_token=1eAbmeGillYAAAAA%3ABNGBB6EuRFXIDWHgsa7E798wfC0MQK2r3yOmAlFzR2sxyD9Xt837VoCel0l6Tsh3RRO19t-YUm1GqO7Y">weight loss in people with obesity</a>, lower levels of <a href="https://link.springer.com/article/10.1186/s12937-020-00557-5">certain types of cholesterol</a>, and <a href="https://journals.lww.com/md-journal/fulltext/2020/02070/Effect_of_green_tea_supplementation_on_blood.36.aspx/1000">reduced blood pressure</a>. Green tea may also <a href="https://www.nature.com/articles/s41430-020-00710-7">lower the risk of certain types of cancer</a>.</p> <p>So, if you can’t get your hands on matcha at the moment, drinking green tea may be a good way to get your caffeine hit.</p> <p>Although the evidence on green tea provides us with some hints about the health benefits of matcha, we can’t be certain they would be the same. Nonetheless, if your local coffee shop has a good supply of matcha, there’s nothing to suggest you shouldn’t keep enjoying matcha drinks.</p> <p>However, it may be best to leave the matcha croissant or cronut for special occasions. When matcha is added to foods with high levels of added sugar, salt and saturated fat, any health benefits that could be attributed to the matcha may be negated.<!-- Below is The Conversation's page counter tag.

Baggage handler calls out crucial mistake at bag-drop

<p dir="ltr">A ramp agent for a major airline has revealed one crucial mistake that many people make when checking their luggage before they fly. </p> <p dir="ltr">Sharing all the details of the little-known trick on a lengthy Reddit thread, the baggage handler, who has years of experience working with American Airlines, noted an extra step that many people miss to ensure the safe arrival of their bags. </p> <p dir="ltr">"Your bag tag has three 'bingo' stickers with your itinerary on them. Take one off and stick it on your suitcase," the airline worker shared.</p> <p dir="ltr">"This way, even if the bag tag gets torn off at some point, we can still get it to its destination."</p> <p dir="ltr">The stickers look like small barcodes at the very end of the long luggage tag and can simply be pulled off and placed anywhere else on the suitcase.</p> <p dir="ltr">It can also be a good idea to keep one of these small tickets with you, whether on your boarding pass (in an area that doesn’t restrict important information), or simply on an old receipt. </p> <p dir="ltr">That way if your luggage unfortunately goes missing, you have the right barcode and number for your bags to be easily located, wherever they may be. </p> <p dir="ltr">Another thing the baggage handler mentions is the location of the luggage tag. </p> <p dir="ltr">While many signs indicate it should be placed around the side handle (if your case has one), the staff member suggests the top handle is better.</p> <p dir="ltr">"Having the tag on the top handle, which is the one that faces outward on the cart, makes it more likely for mistakes to be caught," he points out.</p> <p dir="ltr"><em>Image credits: Shutterstock</em></p>

What to claim for lost, delayed or damaged bags on overseas flights

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/rebecca-johnston-123333">Rebecca Johnston</a>, <a href="https://theconversation.com/institutions/university-of-notre-dame-australia-852">University of Notre Dame Australia</a> and <a href="https://theconversation.com/profiles/david-hodgkinson-6574">David Hodgkinson</a>, <a href="https://theconversation.com/institutions/the-university-of-western-australia-1067">The University of Western Australia</a></em></p> <p>If you get on a plane and your baggage ends up being delayed, damaged or lost, who’s responsible: you or the airline? And what rules apply when you’re flying between different countries – even if you don’t have travel insurance?</p> <p>Airlines (otherwise known as carriers) generally include baggage requirements in their terms and conditions of carriage, which are set out or referred to on your ticket. These are the rules that apply to the journey that you have booked.</p> <p>But for international flights, a carrier’s liability for damage, loss or delay of baggage is governed by a number of overarching international treaties, which many passengers aren’t aware of.</p> <h2>International agreements</h2> <p>The <a href="http://www.jus.uio.no/lm/air.carriage.warsaw.convention.1929/doc.html">Warsaw Convention</a> of 1929 was the first of these treaties, and the latest is the passenger-friendly 1999 <a href="http://www.jus.uio.no/lm/air.carriage.unification.convention.montreal.1999/">Montreal Convention</a>.</p> <p>In order for one of these treaties to apply to a particular journey, the same treaty must be in place at the point of departure and the passenger’s final destination.</p> <p>For many trips, the agreement that will apply will be the Montreal Convention, which has to date <a href="http://www.icao.int/secretariat/legal/List%20of%20Parties/Mtl99_EN.pdf">108 state parties</a>, covering everywhere from Albania and Australia to Zambia. In time, the Montreal Convention is expected to apply to almost all air travel.</p> <p>The Warsaw Convention (as amended by the <a href="http://www.jus.uio.no/lm/air.carriage.warsaw.convention.hague.protocol.1955/doc.html">Hague Protocol</a> and <a href="http://www.jus.uio.no/lm/air.carriage.warsaw.convention.montreal.protocol.4.1975/doc.html">Montreal Protocol No. 4</a>) will generally apply where the Montreal Convention does not. It is less favourable to passengers.</p> <p>All these treaties have similar provisions to deal with baggage claims – but very different limits to what you might get if you need to make a claim.</p> <h2>What the airline is responsible for</h2> <p>A carrier is liable if your checked baggage is lost, delayed or damaged regardless of fault.</p> <p>This is so unless the damage resulted from the inherent defect or quality of the baggage or, in terms of delay, if it proves that it took all reasonable measures to avoid the damage occasioned by that delay.</p> <p>As for unchecked baggage (that is, carry-on baggage), the carrier is only liable if the damage is due to the fault of the carrier or its agents.</p> <p>Unless otherwise specified, reference to “baggage” includes both checked and unchecked baggage.</p> <h2>Calculating baggage compensation</h2> <p>Under the Warsaw Convention (as amended by the <a href="http://www.jus.uio.no/lm/air.carriage.warsaw.convention.hague.protocol.1955/doc.html">Hague Protocol</a> and <a href="http://www.jus.uio.no/lm/air.carriage.warsaw.convention.montreal.protocol.4.1975/doc.html">Montreal Protocol No. 4</a>) and the Montreal Convention, liability limits are expressed in <a href="http://www.imf.org/external/np/exr/facts/sdr.HTM">special drawing rights</a> (SDRs).</p> <p>An SDR is a type of foreign exchange reserve asset created by the International Monetary Fund. Its value is based on an artificial basket of currencies consisting of the US dollar, the euro, the pound and the Japanese yen. The liability limits are reviewed every five years.</p> <p>As of October 16, 2014, the <a href="http://www.imf.org/external/np/fin/data/param_rms_mth.aspx">value of an SDR</a> is about US$1.49, £0.93 or A$1.70. Current SDR values for other currencies are also listed <a href="http://www.imf.org/external/np/fin/data/param_rms_mth.aspx">here</a>.</p> <h2>So what is your baggage worth?</h2> <p>In terms of baggage liability limits, the Warsaw Convention is of relatively little assistance to passengers.</p> <p>If your international travel is subject to Warsaw (for example, if you flew out of the United States on a one way ticket to Guatemala), liability for delayed, damaged or lost baggage is limited to 17 SDRs (about US$25.33, £15.81 or A$28.90) per kilogram per passenger for checked baggage and 332 SDRs (about US$494.68, £308.76 or A$564.40) per passenger for unchecked baggage.</p> <p>In contrast, a carrier is liable to pay far greater damages if the Montreal Convention applies.</p> <p>For any travel covered by Montreal, the carrier’s liability for baggage is limited to 1131 SDRs per passenger (US$1685.19, £1051.83 or A$1922.70), unless otherwise declared.</p> <p>The carrier is not liable for damages caused by delay if the carrier took all reasonable measures, or if it was impossible for it to take such measures.</p> <h2>Time limits on baggage claims</h2> <p>Time limits are imposed on making a claim for delayed, damaged or lost baggage. Any potential claims should be made to a carrier in writing within these specified limits.</p> <p>Article 26 of Warsaw provides that any complaint as to delay of baggage must be made at the latest within 21 days from the date the baggage was placed at the passenger’s disposal.</p> <figure class="align-right zoomable"></figure> <p>Similarly, under Article 31 of Montreal, a complaint must be made within 21 days of a passenger receiving their baggage.</p> <p>With respect to damaged baggage, under Warsaw, any claim must be made “forthwith” after the discovery of the damage and at most seven days from the date of receipt of the baggage. Montreal also gives passengers seven days from receipt of checked bags to report a damage claim.</p> <p>Neither convention imposes a time limit for reporting lost baggage claims. But it is advisable that you make your complaint as soon as possible.</p> <p>Warsaw does not state when baggage is considered “lost”, leaving it up to carriers to make that ruling. Under Montreal, baggage is only considered lost after 21 days or if the carrier admits that they have lost it.</p> <p>If a passenger fails to make a complaint within the specified times, the carrier will not be liable unless there has been fraud on the carrier’s part.</p> <h2>Insurance alternatives</h2> <p>If you are concerned that the contents of your baggage exceed the liability limits outlined above, you can make a special declaration of the value of your baggage prior to check-in and pay any additional fee (if required).</p> <p>In this case, the carrier will be liable to pay a higher amount, unless it is proved that the declared amount is greater than the actual value of your baggage.</p> <p>Alternatively, prior to travelling, check with your insurance company as to whether your travel insurance covers any excess from delayed, damaged or lost baggage.</p> <p>You might also want to <a href="http://www.icao.int/secretariat/legal/List%20of%20Parties/Mtl99_EN.pdf">check this list</a> to see whether the places you’re departing from and finally arriving at are parties to the Montreal Convention. If not, you might just find yourself out of pocket.<!-- Below is The Conversation's page counter tag.

How do we save ageing Australians from the heat? Greening our cities is a good start

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/claudia-baldwin-248780">Claudia Baldwin</a>, <a href="https://theconversation.com/institutions/university-of-the-sunshine-coast-1068">University of the Sunshine Coast</a>; <a href="https://theconversation.com/profiles/jason-byrne-6066">Jason Byrne</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a>, and <a href="https://theconversation.com/profiles/tony-matthews-234160">Tony Matthews</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a></em></p> <p>Heatwaves have killed more Australians than <a href="https://ama.com.au/ausmed/heatwave-health-warning">road accidents</a>, fires, floods and <a href="https://www.sciencedirect.com/science/article/pii/S1462901114000999">all other natural disasters combined</a>.

The <a href="https://theconversation.com/the-stubborn-high-pressure-system-behind-australias-record-heatwaves-110442">record heatwaves</a> have highlighted the damaging effects of heat stress. Understandably, it’s becoming a major <a href="https://ama.com.au/ausmed/heatwaves-nation%E2%80%99s-deadliest-natural-disaster-0">public health challenge</a>.</p> <p>The risk of extreme heat events and the adverse impacts on older people has been extensively <a href="https://jech.bmj.com/content/64/9/753.short">discussed in research</a>. Remarkably, very little attention has been paid to the role of urban greenery in reducing heat stress for seniors.</p> <p>Older people are particularly at risk of heat stress. Pre-existing medical conditions and limited mobility increase their vulnerability. <a href="http://www.cmaj.ca/content/182/10/1053.short">Deaths of older people increase</a> during extreme heat events.</p> <p>The physical features of urban areas shape the capacity of older adults to engage in many activities when it’s hot. These include vegetation volume and coverage, <a href="https://theconversation.com/building-cool-cities-for-a-hot-future-57489">thermal design</a>, and the extent of shading in public areas and walkways. Increasing urban greenery may offer a way to improve older people’s comfort and social experience.</p> <h2>Ageing adds urgency to greening</h2> <p>It is expected <a href="http://www.un.org/en/sections/issues-depth/ageing/">20% of the global population</a> will be older than 60 by 2050. The figure for Australia <a href="http://www.abs.gov.au/ausstats/abs@.nsf/mediareleasesbyTopic/2CA2134677EF9D03CA257C2E0017283B?OpenDocument">is even higher</a>, at 23%. This means that by 2050 around one in four Australians will be more vulnerable to extreme heat.</p> <figure class="align-right zoomable"></figure> <p>Climate change may make the problem worse by <a href="https://www.sciencedirect.com/science/article/pii/S0749379708006867">fuelling even more extreme heat</a> events.</p> <p>Planning our urban centres to meet the needs of a <a href="https://www.aihw.gov.au/reports/older-people/older-australia-at-a-glance/contents/demographics-of-older-australians">rapidly ageing population</a> is a matter of urgency. Urban greening to reduce their vulnerability to heat stress should be central to this agenda. It can also improve people’s quality of life, reduce <a href="https://www.sciencedirect.com/science/article/abs/pii/S1353829208001172">social isolation and loneliness</a>, and ease the burden on health systems.</p> <p>An important task is matching the design of communities with the needs of an ageing population. Where older adults live and the quality of their local areas strongly influence their lived experiences. Yet <a href="https://journals.sagepub.com/doi/abs/10.1177/0885412217704649">recent research</a> found the experiences of seniors were often not accounted for in research on neighbourhood design.</p> <h2>What about aged care?</h2> <p>People face choices about where they live as they age. The common choices are to “<a href="https://theconversation.com/for-australians-to-have-the-choice-of-growing-old-at-home-here-is-what-needs-to-change-91488">age in place</a>” or to move into aged care.</p> <p>Ageing in place includes living in one’s own home or <a href="https://theconversation.com/co-housing-works-well-for-older-people-once-they-get-past-the-image-problem-79907">co-habiting with relatives or friends</a>. Around 90% of Australian seniors <a href="https://www.pc.gov.au/research/completed/housing-decisions-older-australians/housing-decisions-older-australians.pdf">choose this option</a>, with the remainder opting for aged-care facilities.</p> <p>If one in ten Australian seniors live in aged-care facilities, it is clear these should be designed to minimise heat stress. This isn’t just good for residents; it may also benefit operators by lowering health-care and electricity costs.</p> <p>While these facilities are purpose-built for older people, many in Australia were built well over a decade ago, when heat stress was not such a large concern. Many more facilities are being built now and will be into the future. Yet it is uncertain whether they are being actively designed to reduce the impacts of heat.</p> <h2>What has our research found?</h2> <p>We recently conducted a focus group to investigate this issue. Participants were senior managers from four large corporate providers of aged care in Australia. We investigated if and how providers try to minimise heat stress through design. We also sought to understand the rationales used to support these design approaches.</p> <p>Several participants reported on refurbishments that they expect will have cooling effects. Cited design approaches included green roofs and walls, as well as sensory gardens. Other expected benefits included reducing anxiety and improving the mental health of residents.</p> <p>The fact that single design interventions could produce multiple benefits improved the potential for corporate buy-in. Participants expected that increasing green space and green cover would give their facilities a competitive advantage by attracting more clients and providing a better working environment for staff.</p> <p>Participants also reported on challenges of including greening in their projects. For example, the benefits of trees were weighed against concerns about roots disrupting footpaths and becoming trip hazards. Species selection was another concern, with fears that inappropriate plants could die and undermine support for greening programs.</p> <p>Our research suggests that more can be done to make cities hospitable for older people, especially during extreme heat. Urban greening is a start. Encouraging aged-care providers to adopt green infrastructure will have benefits. But we should also consider reforms to planning systems and urban design to better protect older people who choose to age in place.<!-- Below is The Conversation's page counter tag.

"Green cordial" water in Sydney harbour baffles residents

<p>A bay in Sydney Harbour has turned neon green, with authorities currently investigating the cause. </p> <p>Locals were baffled when they saw the bay along Hipwood Street in Kirribilli, near Milsons Park, turn bright green at about 3pm on Wednesday, with many calling the incident "unusual". </p> <p>Firefighters said they were  "alerted to a large spill of fluorescent green material flowing into the harbour".</p> <p>One local described the water as "green cordial" and said it resembled "radioactive stuff you see in superhero movies".</p> <p>NSW Fire and Rescue then conducted several tests and said the water is not toxic and is currently not harming the environment. </p> <p>The Fire and Rescue team are now trying to flush out the green substance, and said that the incoming rain should help turn the water colour back to normal. </p> <p>Another resident told 9News that they had seen green water in a stormwater drain at Anderson Park, along Clark Road, on Tuesday, before the green colour spread to the bay on Wednesday.</p> <p>Later in the afternoon, a North Sydney Council spokeswoman confirmed that were no major pollutants in the green water: “At this stage our engineers believe the substance is likely to be fluorescein, which is used as a dye for plumbing works. Fluorescein is a non-toxic substance and breaks down with UV light. The green colour is a feature that makes it easy to trace.” </p> <p>Green water was also spotted in Neutral Bay on Wednesday according to another local. </p> <p><em>Image: Nine</em></p>

“Hypocrite”: Hughesy's on-air clash with Greens leader

<p>Dave “Hughesy” Hughes had a fiery debate with Australian Greens Leader Adam Bandt about veganism on-air on<em> </em>The Fox’s <em>Fifi, Fev &amp; Nick</em>. </p> <p>Before Bandt appeared on the show, a clip played of Hughesy, who is a vegan, calling for the leader to "quit the party" after learning the Greens leader wasn't a vegan. </p> <p>He questioned how Bandt could advocate for climate action without adopting a plant-based lifestyle, and the Greens leader was brought onto the show to explain his stance. </p> <p>“So you are not a vegan?” Hughesy asked the politician. </p> <p>“I’m not….” replied Bandt. “I applaud those who are, I applaud those who have made the shift. I’ve been thinking about it …”</p> <p>Hughesy then loudly interjected “ … URGH, THINKING ABOUT IT?”</p> <p>The Greens leader replied: “I don’t have a good drop-dead reason, but I’ve been thinking about it, and I can probably give you three justifications for it.</p> <p>"Firstly, we’ve made big changes at home and basically only eat meat for special occasions, the rest of the time we’re vegan or vegetarian at home.”</p> <p>“…. THERE’S ONE WAY, ADAM, THERE’S ONE WAY …” the presenter yelled in response. </p> <p>Hughesy's co-star Fev then tried to make light of the situation and asked him:  “What are you doing Dave?"</p> <p>"Adam is doing the version of Leonardo DiCaprio and his private jet flying around the world while banging on about climate change, but you flew to Brisbane on the weekend,” he continued suggesting that Hughesy too was being a hypocrite by getting on a flight recently. </p> <p>“But I don’t bang on about it,” exclaimed Hughesy.</p> <p>“Adam is the leader of the Greens … it’s hypocritical! C’mon, you can do it, Adam, you can become a vegan! Be the change you want to see in the world, buddy!”</p> <p>Hughesy adopted the vegan lifestyle for his own health, but he has previously revealed that it comes with its challenges and his family were also not that enthusiastic about the change. </p> <p><em>Image: news.com.au/ Fifi, Fev &amp; Nick</em></p>

Aussie cancer survivor bags Olympic medal

<p><sub>Australian cyclist Matthew Glaetzer has won his first ever medal at his fourth and final Olympic games. </sub></p> <p><sub>After overcoming injury, heartbreak and even thyroid cancer, the 31-year-old, dubbed by many as cycling's unluckiest man, has finally won a bronze medal. </sub></p> <p><sub>Two years before the Tokyo Olympics, the athlete received a thyroid cancer diagnosis, surgery and treatment. </sub></p> <p><sub>He was then hit by a series of injuries including a torn calf, oblique complaint and bulging disc in his back, but that didn't stop him from competing in Tokyo. </sub></p> <p><sub>While he didn't win any medals, he refused to let a career of near-misses define him and finally achieved bronze in the team sprint alongside Leigh Hoffman and Matt Richardson this year. </sub></p> <p><sub>“It was elation — I was so pumped when I saw that ‘three’ ... on the scoreboard,” Glaetzer said after the race.</sub></p> <p><sub>“It’s very special to finally win an Olympic medal.

Do red bags get loaded onto a plane first? Travel hack goes viral

<p>One TikTok user has racked up over 75 million views for their hack which warns travellers against buying red suitcases.</p> <p>The reason behind it? He claims that red suitcases are always loaded onto a plane first - meaning that they will be the last ones to come out at the baggage carousel. </p> <p>The <a href="https://www.tiktok.com/@airportlife_/video/7359248989134327072" target="_blank" rel="noopener">viral video</a> showed a plane's cargo being loaded, with all the red bags being loaded first. </p> <p>Many commenters have shared their theories on why this might be the case. </p> <p>"If the red are at the back then they are less likely to get left behind when unloading," one wrote. </p> <p>"So that it's easier to check if there is any bag left at end corner of loading area and prevent missing out black bags at dark corners, maybe," another added. </p> <p>However, a spokesperson for KLM Royal Dutch Airlines has debunked this theory and claimed that the video is "nonsense" and "was made purposefully to mislead or provide false information".</p> <p>They also said that there was simply not enough time for their baggage handlers to sort suitcases out by colour. </p> <p>The question of "Do red bags get loaded onto a plane first?" also made its way to Reddit, after the video went viral, and one user who claimed to be a ramp worker denied the theory. </p> <p>"If we had taken the time and brain power to load bags based on colour I'd still be loading flights from 2015." </p> <p><em>Image: TikTok</em></p>

Why do airlines charge so much for checked bags? This obscure rule helps explain why

<p><em><a href="https://theconversation.com/profiles/jay-l-zagorsky-152952">Jay L. Zagorsky</a>, <a href="https://theconversation.com/institutions/boston-university-898">Boston University</a></em></p> <p>Five out of the six <a href="https://www.oag.com/blog/biggest-airlines-in-the-us">biggest U.S. airlines</a> have <a href="https://www.cnbc.com/2024/03/05/delta-is-the-latest-airline-to-raise-its-checked-bag-fee.html">raised their checked bag fees</a> since January 2024.</p> <p>Take American Airlines. In 2023, it cost US$30 to check a standard bag in with the airline; <a href="https://www.usatoday.com/story/travel/airline-news/2024/02/20/american-airlines-bag-fees-mileage-earning/72669245007/">today, as of March 2024, it costs $40</a> at a U.S. airport – a whopping 33% increase.</p> <p>As a <a href="https://www.bu.edu/questrom/">business school</a> <a href="https://www.bu.edu/questrom/profile/jay-zagorsky/">professor who studies travel</a>, I’m often asked why airlines alienate their customers with baggage fees instead of bundling all charges together. <a href="https://www.vox.com/2015/4/16/8431465/airlines-carry-on-bags">There are</a> <a href="https://www.usatoday.com/story/travel/columnist/2023/06/21/bag-fees-will-stay-a-while-cruising-altitude/70338849007/">many reasons</a>, but an important, often overlooked cause is buried in the U.S. tax code.</p> <h2>A tax-law loophole</h2> <p>Airlines pay the federal government <a href="https://www.ecfr.gov/current/title-26/chapter-I/subchapter-D/part-49/subpart-D">7.5% of the ticket price</a> when <a href="https://www.pwc.com/us/en/services/tax/library/aircraft-club-nov-2023-air-transport-excise-tax-rates-for-2024.html">flying people domestically, alongside other fees</a>. The airlines dislike these charges, with their <a href="https://www.airlines.org/dataset/government-imposed-taxes-on-air-transportation/">trade association arguing</a> that they boost the cost to the consumer of a typical air ticket by around one-fifth.</p> <p>However, the U.S. Code of Federal Regulations <a href="https://www.ecfr.gov/current/title-26/chapter-I/subchapter-D/part-49/subpart-D/section-49.4261-8">specifically excludes baggage</a> from the 7.5% transportation tax as long as “the charge is separable from the payment for the transportation of a person and is shown in the exact amount.”</p> <p>This means if an airline charges a combined $300 to fly you and a bag round-trip within the U.S., it owes $22.50 in tax. If the airline charges $220 to fly you plus separately charges $40 each way for the bag, then your total cost is the same — but the airline only owes the government $16.50 in taxes. Splitting out baggage charges saves the airline $6.</p> <p>Now $6 might not seem like much, but it can add up. Last year, passengers took <a href="https://www.transtats.bts.gov/Data_Elements.aspx?Data=1">more than 800 million trips on major airlines</a>. Even if only a fraction of them check their bags, that means large savings for the industry.</p> <p>How large? The government has <a href="https://www.bts.dot.gov/topics/airlines-and-airports/baggage-fees-airline-2023">tracked revenue from bag fees</a> for decades. In 2002, airlines charged passengers a total of $180 million to check bags, which worked out to around 33 cents per passenger.</p> <p>Today, as any flyer can attest, bag fees are a lot higher. Airlines collected over 40 times more money in bag fees last year than they did in 2002.</p> <p>When the full data is in for 2023, <a href="https://www.bts.dot.gov/baggage-fees">total bag fees</a> will likely top $7 billion, which is about $9 for the average domestic passenger. <a href="https://viewfromthewing.com/the-real-reason-airlines-charge-checked-bag-fees-and-its-not-what-you-think">By splitting out the cost of bags</a>, airlines avoided paying about half a billion dollars in taxes just last year.</p> <p>In the two decades since 2002, flyers paid a total of about $70 billion in bag fees. This means separately charging for bags saved airlines about $5 billion in taxes.</p> <p><iframe id="88MYD" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/88MYD/2/" width="100%" height="400px" frameborder="0"></iframe></p> <p>It seems clear to me that tax savings are one driver of the unbundling of baggage fees because of a quirk in the law.</p> <p>The U.S. government doesn’t apply the 7.5% tax to <a href="https://www.ecfr.gov/current/title-26/chapter-I/subchapter-D/part-49/subpart-D/section-49.4261-3">international flights that go more than 225 miles</a> beyond the nation’s borders. Instead, there are fixed <a href="https://www.airlines.org/dataset/government-imposed-taxes-on-air-transportation">international departure and arrival taxes</a>. This is why major airlines charge $35 to $40 <a href="https://www.aa.com/i18n/travel-info/baggage/checked-baggage-policy.jsp">for bags if you’re flying domestically</a>, but don’t charge a bag fee when you’re flying to Europe or Asia.</p> <h2>Do travelers get anything for that money?</h2> <p>This system raises an interesting question: Do baggage fees force airlines to be more careful with bags, since customers who pay more expect better service? To find out, I checked with the Bureau of Transportation Statistics, which has been <a href="https://www.bts.gov/content/mishandled-baggage-reports-filed-passengers-largest-us-air-carriersa">tracking lost luggage for decades</a>.</p> <p>For many years, it calculated the number of mishandled-baggage reports per thousand airline passengers. The government’s data showed mishandled bags peaked in 2007 with about seven reports of lost or damaged luggage for every thousand passengers. That means you could expect your luggage to go on a different trip than the one you are taking about once every 140 or so flights. By 2018, that estimate had fallen to once every 350 flights.</p> <p>In 2019, the government <a href="https://www.bts.gov/topics/airlines-and-airports/number-30a-technical-directive-mishandled-baggage-amended-effective-jan">changed how it tracks</a> mishandled bags, calculating figures based on the total number of bags checked, rather than the total number of passengers. The new data show about six bags per thousand checked get lost or damaged, which is less than 1% of checked bags. Unfortunately, the data doesn’t show improvement since 2019.</p> <p>Is there anything that you can do about higher bag fees? Complaining to politicians probably won’t help. In 2010, two senators <a href="https://www.nj.com/business/2010/04/us_senators_present_bill_to_ba.html">tried to ban bag fees</a>, and their bill went nowhere.</p> <p>Given that congressional action failed, there’s a simple way to avoid higher bag fees: <a href="https://www.cnn.com/travel/article/packing-expert-travel-world-handbag/index.html">travel light</a> and <a href="https://www.nytimes.com/2023/07/08/opinion/carry-on-packing-airlines-lost-luggage.html">don’t check any luggage</a>. It may sound tough not to have all your belongings when traveling, but it might be the best option as bag fees take off.<!-- Below is The Conversation's page counter tag.

Eating leafy greens could be better for oral health than using mouthwash

Aussie grandma and former Greens candidate jailed in Japan claims she was scammed

<p>Donna Nelson, a 57-year-old Perth grandmother, has found herself entangled in a nightmarish situation in a Japanese prison, accused of a crime she vehemently denies.</p> <p>Nelson, an Aboriginal health advocate and former Greens candidate, has been incarcerated for nearly a year without a trial date set, facing allegations of attempting to smuggle two kilograms of meth into Japan. However, her plight is not as straightforward as it may seem, and her family and legal team are tirelessly fighting to clear her name.</p> <p>The ordeal began on January 4, when Nelson was arrested at Narita Airport in Tokyo. Authorities claimed to have discovered drugs concealed within a false compartment in her luggage. According to the prosecution, a customs officer suspected her of acting suspiciously. But the narrative has taken a complex turn as Nelson's defence team unveiled a shocking revelation: she alleges she was deceived and manipulated by a Nigerian scammer who had groomed her for two years.</p> <p>Since her arrest, Nelson has been confined to Chibu prison, located an hour outside Tokyo. Her living conditions are appalling; she spends 23 hours a day isolated in her cell, showers are allowed only every three days, and communication with other inmates and visitors is strictly prohibited. This form of treatment is a reflection of Japan's infamous "hostage justice" strategy, aimed at coercing confessions from detainees.</p> <p>The only individuals granted access to Nelson are her lawyers, Australian embassy representatives, and a pastor. Legal representatives have identified a significant issue with translation throughout the case, and it could very well hinge on an inaccurate translation by the customs officer at the time of her arrest.</p> <p>Rie Nishida from Shinjuku International Law Firm, one of Nelson's lawyers, explained, "The main evidence from the prosecution is mainly a customs officer who said she acted suspiciously. There's a lot of mistranslation that's also the difficulty in this case."</p> <p>This mistranslation issue is not trivial; it extends to the messages exchanged between Nelson and the man she believed she had a romantic connection with, who ultimately turned out to be a scammer.</p> <p>Matthew Owens, another member of the legal team and a translator for the case, noted, "Some of them were completely wrongly translated, so we had to re-translate those messages and submit them back to the prosecutor."</p> <p>Nelson remains steadfast in her conviction that she is innocent of the accusations against her. Her lawyer,  Owens, relayed her message, saying, "Donna wants to say that she is going to be able to prove her innocence, she's 100 per cent confident of that, and she wants everyone in Australia and the world to know she is innocent."</p> <p>If found guilty, Nelson could face a harrowing 20-year sentence in a Japanese prison, a terrifying prospect for both her and her family. Her five daughters and grandchildren are distraught, but they are not giving up the fight to prove her innocence. They believe they have evidence to substantiate the claim that she was scammed and unjustly accused.</p> <p><em>Image: Australian Greens</em></p>

Why does my hair turn green from the swimming pool?

<p><em><a href="https://theconversation.com/profiles/magdalena-wajrak-1432339">Magdalena Wajrak</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a></em></p> <p>If you are a blonde like me and enjoy laps in a swimming pool, you may have noticed your hair acquires a green tint after frequent swims in chlorinated water.</p> <p>This happens to both bleached and natural blondes. In fact, the green tinge happens to everyone, but it’s less visible on dark hair and those whose hair isn’t damaged by chemical treatments such as bleaching.</p> <p>But what exactly causes this green discoloration, and what can we do about it? Most of us blame the chlorine in the pool water. However, although chlorine does play a part, it is not the main culprit.</p> <h2>Which chemicals in the pool turn the hair green?</h2> <p>The element to blame for the green staining of hair is copper.</p> <p>The main source of copper is copper sulfate (CuSO₄), a compound added to swimming pools to prevent the growth of algae. <a href="https://www.sciencedirect.com/science/article/pii/S1568988320301803?via%3Dihub">Contact with algae</a> can cause skin irritation and respiratory issues, and ingesting water with algae can lead to serious gastrointestinal problems. Only a small amount (around 0.5mg per litre or 0.5 parts per million) of copper sulfate is needed to prevent algal growth.</p> <p>However, copper can also enter swimming pools through the corrosion of water pipes, so concentrations may be higher in some pools.</p> <p>Copper sulfate crystals are greenish-blue in colour. So, when hair comes into contact with copper ions – a positively charged variant of a copper atom with extra electrons – those ions get absorbed by the hair and cause the greenish hue.</p> <p>Scientists were fascinated by the green “pool hair” phenomenon as far back as the 1970s, so we actually have research data on copper being the cause.</p> <p>One very <a href="https://jamanetwork.com/journals/jamadermatology/article-abstract/538197">interesting study in 1978</a> performed experiments by immersing hair samples into water containing different concentrations of copper ions, chlorine and various pH values (neutral and basic). Their results showed hair exposed to free copper ions does turn green.</p> <p>Furthermore, when hair is oxidised (meaning electrons are removed from the hair proteins) by chlorine, it actually damages the hair, enhancing the absorption of copper ions. Hair submerged in water with chlorine but without copper ions did not turn green. Meanwhile, hair exposed to water with only copper ions and no chlorine still formed a green colour.</p> <p>Hence, chlorine by itself does not play a role in causing the green hue we see in “pool hair”, but it does exacerbate it.</p> <h2>So, how does copper get into the hair?</h2> <p><a href="https://doi.org/10.1007/978-1-4684-0943-7_24">Other research teams</a> have conducted <a href="https://doi.org/10.1071/ch9682437">more extensive studies</a>, using sophisticated instruments, such as scanning electron microscopy, to examine how exactly copper ions attach to the hair.</p> <p>Our hair is predominantly composed of protein called keratin. Keratin is classified as a “structural fibrous protein”, meaning it has an elongated, sheet-like structure.</p> <p>The keratin structure is composed of various <a href="https://chem.libretexts.org/Courses/University_of_Kentucky/UK%3A_CHE_103_-_Chemistry_for_Allied_Health_(Soult)/Chapters/Chapter_4%3A_Structure_and_Function/4.4%3A_Functional_Groups">chemical groups</a> (types of atom groupings with similar properties), such as carboxyl groups, amino groups and disulfide groups. Copper ions have the ability to form bonds with these groups, forming a copper-keratin complex. This complex remains in the hair, causing it to appear green.</p> <p>Interestingly, the most recent study <a href="https://doi.org/10.32657/10356/142466">conducted in 2020</a>, showed copper ions mainly bind to the disulfide groups. This study also found other metal ions such as zinc, lead, chromium and mercury also bind to hair in the same way. This is very useful in <a href="https://theconversation.com/forensic-breakthrough-study-suggests-humans-can-be-identified-by-the-proteins-in-their-hair-65051">forensic analysis</a>, for example, because forensic scientists can analyse hair samples to determine if a person has been exposed to a particular metal.</p> <p>Light-coloured hair already has the most visible green discoloration, but research has shown that damaged hair, caused by bleaching, straightening, or exposure to sun, is the <a href="https://pubmed.ncbi.nlm.nih.gov/19586601/">most susceptible</a> to the binding of copper ions. This is because in damaged hair the disulfide groups have “broken bonds” (the link that holds the elements within these groups together is broken), making it easier for the copper ions to bind to the hair.</p> <h2>Can I prevent the green colour or get rid of it?</h2> <p>To prevent your hair from turning green in a swimming pool, you have two basic options. The first is a physical barrier – just wear a swim cap.</p> <p>The second option is chemical – you can pre-treat your hair with an alkaline shampoo. <a href="https://www.sciencedirect.com/science/article/abs/pii/S0891584918310050">Studies have shown</a> under alkaline pH conditions, the copper ions won’t attach to the hair. To treat your hair before going to the pool, you can either use a shampoo with a pH higher than 7, or you can even try mixing some baking soda into your regular shampoo.</p> <p>But what can you do if your hair has already turned greenish? Well, you can try washing your hair with a shampoo designed to achieve this, typically marketed as a “chlorine removal” shampoo. These products contain a chemical called EDTA – it can bind to metal ions (such as copper) and thus will remove copper from the hair.</p> <p>You may have heard tomato sauce or ketchup is a good way to get the green out of your pool hair – potentially because the red pigments are supposed to “cancel out” the green ones. However, I’m not aware of any scientific evidence this would work.</p> <p><em>Correction: This article has been amended to clarify that alkaline shampoos have a pH higher than 7, not lower.</em><!-- Below is The Conversation's page counter tag.

My Royal Melbourne Seniors Classic Adventure: A day on the greens (and in the bunkers!)

<p dir="ltr">G'day to all past, present, and emerging golf enthusiasts!</p> <p dir="ltr">If you're a senior golfer like me, hunting for inspiration, adventure, and authentic golf yarns — this is for you.</p> <p dir="ltr">Picture this: a crisp August morning, and sixty-two senior golfers gathered on Royal Melbourne's West Course for the Vic Seniors Classic 2023. Here's the story of how it all went down...</p> <p dir="ltr">Before anything else, I mustered the guts to jump in. Ever heard of "imposter syndrome"? Trust me, I was its best mate. But the requirements were clear: age 55+ (I'm a proud 65-year-old), GA Handicap under 24.5 (18.5), and a $225 entry fee. Wait, $225? Given that Royal Melbourne's green fees dance around $1000, caddy fee included, it was a no-brainer.</p> <p dir="ltr">Fueled by the temptation of playing a top-notch course for a quarter of the fee, I submitted my application without hesitation. Before I knew it, my name adorned the list of players.</p> <p dir="ltr">As the day approached, I was geared up to tackle the Royal Melbourne challenge.</p> <p dir="ltr">The 8 am shotgun start meant groups teed off from various holes. I found myself at the 11th tee, flanked by two fierce competitors: Peter (Daily Handicap 1) and Damian (12). Yours truly? A modest 20.</p> <p dir="ltr">Standing over the ball, knees a tad wobbly, I swung that driver. The ball sailed gracefully, landing centre fairway, while their shots had taken a wilder route into the rough. The lesson? 'How near,' not 'how far'.</p> <p dir="ltr">Now, let's talk about those Royal Melbourne greens. Rumour had it, they were "super fast". Super fast? Imagine sliding a ball across your kitchen's polished tiles — yep, that rapid.</p> <p dir="ltr">Around the course, bunkers became my stern mentors — big, deep, and oh-so unforgiving.</p> <p dir="ltr">Post 18 holes, scorecards were in, followed by the triumphant crowning of winners over lunch.</p> <p dir="ltr">Rodney Ware (75 gross) and Kevin Naismith (81 gross) led in men's gross, while Wayne Moon (72 net) and Craig Lonsdale (73 net) dominated the net division. Melinda Crawford (16, scratch stableford) and Louise Yuen (29 handicap points) shone in the women's.</p> <p dir="ltr">Kudos to winners, fellow players, Royal Melbourne and Golf Australia for the unforgettable day.</p> <p dir="ltr">By the way, can you see yourself on those hallowed Royal Melbourne greens? If your inner golfer nods, I'm your cheerleader. Consider joining me for the 2024 Royal Melbourne Seniors Classic.</p> <p dir="ltr">And as I wrap up, let me leave you with the timeless words of the legendary Peter Thomson: "Golf is a game of how near, not how far".</p> <p dir="ltr">Until next time, keep those swings buttery, putts steadfast, and steer clear of those tricky bunkers.</p> <p dir="ltr">PS: My result? T43rd (net) among the 48 male players. Next time I'll be swinging even better.</p> <p dir="ltr"><strong><em>About the Writer: Mike Searles is a Melbourne retiree who's living the golfing dream.</em></strong></p> <p><em>Image credits: Getty Images</em></p>

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>

Why do I have to take my laptop out of the bag at airport security?

<p><em><a href="https://theconversation.com/profiles/doug-drury-1277871">Doug Drury</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a></em></p> <p>Anyone who has travelled by air in the past ten years will know how stressful airports can be.</p> <p>You didn’t leave home as early as you should have. In the mad rush to get to your gate, the security screening seems to slow everything down. And to add insult to injury, you’re met with the finicky request: “laptops out of bags, please”.</p> <p>But what does your laptop have to do with security?</p> <h2>The day that changed air travel forever</h2> <p>Airport security changed dramatically after the terrorist attacks in the US on September 11 2001. Before 9/11, you could pass through security with a carry-on bag full of everything you might need for your holiday, <a href="https://www.npr.org/2021/09/10/1035131619/911-travel-timeline-tsa">including a knife</a> with a four-inch blade. Indeed, that’s how the 9/11 attackers brought their <a href="https://www.npr.org/2021/09/10/1035131619/911-travel-timeline-tsa">weapons on board</a>.</p> <p>After 9/11, screening processes around the world changed overnight. In the US, private security contractors being paid a minimum wage were swapped out for a federalised program with highly trained security personnel. Anything that could be <a href="https://www.frontiersin.org/articles/10.3389/fnhum.2013.00654/full">considered a weapon</a> was confiscated.</p> <p>Around the world, travellers were suddenly required to <a href="https://books.google.com.au/books?hl=en&amp;lr=&amp;id=6hBnJ-1hRp0C&amp;oi=fnd&amp;pg=PA86&amp;dq=why+do+I+have+to+take+my+shoes+off+at+airport+security&amp;ots=o6JIFHJzF1&amp;sig=B6azb6xqN2uxM9CP-VZdfyt3Ag0#v=onepage&amp;q=why%20do%20I%20have%20to%20take%20my%20shoes%20off%20at%20airport%20security&amp;f=false">remove their shoes</a>, belts and outerwear, and take out their phones, laptops, liquids and anything else that could be used as part of an improvised explosive device.</p> <p>This lasted for several years. Eventually, <a href="https://www.sciencedirect.com/science/article/pii/S2212478013000944">more advanced</a> screening methods were developed to effectively identify certain threats. Today, some countries don’t require you to remove your shoes when passing through security.</p> <p>So why must you still take your laptop out?</p> <h2>Airport scanners have come a long way</h2> <p>The machine your bags and devices pass through is an X-ray machine.</p> <p>The main reason you have to remove your laptop from your bag is because its <a href="https://www.smh.com.au/traveller/reviews-and-advice/why-do-i-have-to-remove-my-laptop-from-my-bag-at-the-airport-xray-machine-20170320-gv1vqs.html">battery</a> and other mechanical components are too dense for X-rays to penetrate effectively – especially if the scanning system is old. The same goes for power cords and other devices such as tablets and cameras.</p> <p>With these items in your bag, security officials can’t use the screened image to determine whether a risk is present. They’ll have to flag the bag for a physical search, which slows everything down. It’s easier if all devices are removed in the first place.</p> <p>A laptop inside a bag can also shield other items from view that may be dangerous. Scanning it separately reveals its internal components on the screen. In some cases you might be asked to turn it on to prove it’s an actual working computer.</p> <p>With newer multi-view scanning technology, security officials can view the bag from multiple angles to discern whether something is being covered up, or made to look like something else. For instance, people have tried to <a href="https://www.sciencedirect.com/science/article/pii/S2212478013000944">mix gun parts</a> with other components in an effort to pass checked baggage screening.</p> <p>Some airports have upgraded <a href="https://www.smh.com.au/traveller/inspiration/no-more-removing-liquids-and-gels-laptops-at-melbourne-airport-as-new-scanners-installed-20191002-h1ijdf.html">3D scanning</a> that allows travellers to pass their bags through security without having to remove their laptops. If you’re not asked to take out your laptop, it’s probably because one of these more expensive systems is being used.</p> <p>Nonetheless, amping up the technology won’t remove the lag caused by airport screenings. Ultimately, the reason these are a major choke point is because of the speed at which staff scan the imagery (which dictates the <a href="https://www.sciencedirect.com/science/article/pii/S2212478013000944">speed of the conveyor belt</a>).</p> <p>Unless we find a way to automate the entire process and run it with minimal human supervision, you can expect delays.</p> <h2>What about body scanners?</h2> <p>But your bags aren’t the only thing getting scanned at airport security. You are too!</p> <p>The tall frame you walk through is a <a href="https://science.howstuffworks.com/transport/flight/modern/airport-security3.htm">metal detector</a>. Its purpose is to uncover any weapons or other illegal objects that may be concealed under your clothes. Airport metal detectors use non-ionising radiation, which means they don’t emit X-rays.</p> <p>The larger body scanners, on the other hand, are a type of X-ray machine. These can be <a href="https://www.sciencedirect.com/science/article/pii/S2212478013000944">active or passive</a>, or a combination of both.</p> <p>Passive scanners simply detect the natural radiation emitted by your body and any objects that might be concealed. Active scanners emit low-energy radiation to create a scan of your body, which can then be analysed.</p> <p>The kind of machine you walk through will depend on where in the world you are. For instance, one type of active body scanner that emits X-rays in what’s called “backscatter technology” was once <a title="https://electronics.howstuffworks.com/gadgets/high-tech-gadgets/backscatter-x-ray.htm" href="https://electronics.howstuffworks.com/gadgets/high-tech-gadgets/backscatter-x-ray.htm" target="_blank" rel="noopener">used widely</a> in the US, but is no longer used. It’s also banned in <a title="https://www.homeaffairs.gov.au/about-us/what-we-do/travelsecure/passenger-screening" href="https://www.homeaffairs.gov.au/about-us/what-we-do/travelsecure/passenger-screening" target="_blank" rel="noopener">Australia</a> and <a title="https://www.forbes.com/sites/daviddisalvo/2011/11/15/europe-bans-airport-body-scanners-over-health-and-safety-concerns/" href="https://www.forbes.com/sites/daviddisalvo/2011/11/15/europe-bans-airport-body-scanners-over-health-and-safety-concerns/" target="_blank" rel="noopener">the European Union</a>, where only non-ionising technology can be used.</p> <p>Another type of scanner emits lower-energy <a href="https://science.howstuffworks.com/backscatter-machines-vs-millimeter-wave-scanners.htm">millimetre waves</a>, instead of X-rays, to image the passenger. Millimetre wave frequencies are considered to be non-ionising radiation.</p> <h2>AI in our airports</h2> <p>AI seems to be all around us lately, and our airports are no exception. Advancements in AI systems stand to transform the future of airport security.</p> <p>For now, human reviewers are required to identify potential threats in scanned images. However, what if an advanced <a href="https://thinkspace.csu.edu.au/artiificialintelligenceinsecuritycheck/article/">AI was trained</a> to do this using a database of images? It would do so in a fraction of the time.</p> <p>Some airports are already using advanced <a href="https://www.in-security.eu/index.php/editorial/the-future-of-airport-security-faster-smarter-safer">computed tomography</a> (CT) <a href="https://www.theguardian.com/australia-news/2022/jun/21/3d-body-scanners-at-australian-airports-what-are-they-and-how-do-they-work">scanners</a> to produce high-definition 3D imagery. In the future, this technology could be further enhanced by AI to detect threats at a much faster rate.</p> <p>Hypothetically, CT scans could also be used for both humans and their baggage. Could this allow travellers to walk through a body scanner while carrying their bags? Possibly.</p> <p>Until then, you should probably try your best to leave the house on time.<!-- Below is The Conversation's page counter tag.

<p>A mysterious liquid has turned a popular public rock pool at Cronulla beach fluorescent green.</p> <p>The liquid, believed to be a natural fluorescent dye, fluorescein, was seen pouring into the usually clear waters of the pool on Friday.</p> <p>The dye is often used to help experts track the flow of water to identify any leaks and has low toxicity, which means it is harmless despite the daunting colour.</p> <p>“We believe the discolouration is likely to be fluorescein dye, which is commonly used in plumbing/drain testing and dissipates quickly once diluted,” a spokesperson for the New South Wales Environmental Protection Authority said.</p> <p>According to Australian dye manufacturer, Tintex, the dye is also used to “locate leaks in plumbing, tracing pipe locations, detect drain damage and water pathways,” and is odourless and non-toxic to the environment.</p> <p>However, in a safety data sheet, Tintex has also warned about the potential health effects which include eye irritation, skin irritation, irritation of the digestive tract and respiratory tract irritation.</p> <p>Many locals are cautious despite the claim that the dye is mostly harmless.</p> <p>One user wrote on a Facebook page for Cronulla locals that dye was “legal to use in a stormwater drain”.</p> <p>“Doesn’t look good whatever it is,” another responded, while other cautious residents replied that they wouldn’t swim in the area until the dye fully dissipates.</p> <p><em>Images: Facebook</em></p>

How to make your next holiday better for the environment

<p><a href="https://theconversation.com/profiles/brendan-canavan-228682">Brendan Canavan</a>, <em><a href="https://theconversation.com/institutions/university-of-nottingham-1192">University of Nottingham</a></em></p> <p>Being an environmentally friendly tourist can be challenging. Tourism is an industry that brings many <a href="https://www.unwto.org/EU-guidebook-on-sustainable-tourism-for-development">negative environmental impacts</a> – our pleasure often comes at the expense of local habitats or wildlife.</p> <p>Maya Bay on Thailand’s uninhabited Phi Phi Leh island became famous as the location of the 2000 Hollywood movie The Beach. But this led to rapid growth in visitors to the bay – as many as 8,000 a day at its peak – and put enormous strain on the bay’s natural habitats.</p> <p>In 2018, the bay was <a href="https://edition.cnn.com/travel/article/maya-bay-thailand-recovery-c2e-spc-intl/index.html">closed to tourists</a> for four years to let its coral reefs and wildlife recover.</p> <p>But tourism can also be an inspiring way to connect with oneself, with others and with new places. As tourists, we can learn, share and contribute to positive environmental practices.</p> <p>As a tourist, you also have influence. The money you spend, the social interactions you have and the resources you consume all <a href="https://www.sciencedirect.com/science/article/abs/pii/S0261517715300224?casa_token=TaXMOLW6Sp4AAAAA:PEnSG1AaAZ-MiuTNZ1wJfLRrzaNVIbaBsk1cKsP8M-_6KjruLO9tp09BqqzGnJTIZbN8_CoP4Q">help to shape an area</a>.</p> <p>So here are four pieces of advice for making your next holiday better for the environment.</p> <h2>Spend locally</h2> <p>We’ve all heard variations on the mantra “<a href="https://cleanisland.org/history-of-the-leave-only-footprints-initiative/#:%7E:text=%E2%80%9CTake%20only%20memories%2C%20leave%20only,the%20Leave%20Only%20Footprints%20program.">take only memories, leave only footprints</a>”. This message of less consumption and lower impact is a good ethos for environmentally sensitive tourism. The first thing to do is think about how you can leave more positive footprints behind.</p> <p>An excellent way to make the most of your economic footprint is to stay and shop in <a href="https://www.tandfonline.com/doi/full/10.1080/09669580802359293?casa_token=eNeLWWRPHxIAAAAA:9bT4S5-0O5b2JQWrYKgmjtDxrZzlv0P-H-9T2SoWT1fX6tFRkoVenNNcfmJbHV9ebhF2kP7XIEgz">independent businesses</a>. These businesses tend to pay local taxes and are owned by and employ local people. More of the money you spend stays in the immediate area as a result.</p> <p>Where tourist money directly benefits local people and businesses, their support for conservation is <a href="https://www.jstor.org/stable/pdf/26069456.pdf?casa_token=rdKkHk5QviUAAAAA:2ZCqsGG1f-2wFTIdmptbrJDVo8iPjYnam7QPdHXviRy_e0wA7YMY7fc0Qm1smIII4cg6_WriJ1OQwPvxMibmeHQxnO81NPd9jwoeVRudUS2TVv2TNeg">often encouraged</a>. Tourists <a href="https://www.sciencedirect.com/science/article/pii/S0261517709000120#sec5">visiting rhino sanctuaries</a> in Botswana, for example, bring income and support jobs.

Treading carefully will minimise the environmental impact you have on your holiday destination.</p> <p>A simple way to lower your environmental footprint is to use fewer resources at every stage of your holiday. A single tourist uses <a href="https://www.e-unwto.org/doi/pdf/10.18111/9789284414529">300 litres</a> of water in their holiday accommodation on average each night. Reusing towels, flushing the toilet less and shortening your shower time can all help to reduce demand for water resources.</p> <p>Thinking about the footprints you leave as a tourist is a useful mindset. You may even become more aware of the positive legacy you can leave behind.</p> <p>Learn about the local area and the environmental issues that matter there. If habitat loss is a problem, contribute to local organisations that support conservation. Organisations like the <a href="https://www.nationaltrust.org.uk/holidays">National Trust</a> even offer holidays in the UK that help to fund their work.</p> <h2>Place matters</h2> <p>Tourism shifts you away from the familiar and gives you <a href="https://www.sciencedirect.com/science/article/abs/pii/S0160738312001211?casa_token=zHTCleS_F3kAAAAA:jWMOOtEJzH8OXySUqafP5Z7koLFOtNSJ2Ik4ncoA9wPCHTW-1MRNJJwRvYtoopoSqCwTRm_TeA">space for self-reflection</a>. Research has found that people have been <a href="https://www.tandfonline.com/doi/abs/10.1080/02508281.2017.1342349?role=button&amp;needAccess=true&amp;journalCode=rtrr20">inspired by travel to make life changes</a> such as relocating or shifting career.</p> <p>Many keen rock climbers, for instance, adopt a <a href="https://www.tandfonline.com/doi/pdf/10.1080/17450101.2014.977667?casa_token=gCsYfe0mSDkAAAAA:q8f6HbQ9rlwXS5_DGl3De1XUnHXX6U0EC3QUNz65pFivUgPo7RDH0-zGXvspjrTrv73FKkouDPM-">minimalist and mobile lifestyle</a>. <a href="https://www.tandfonline.com/doi/full/10.1080/14616688.2012.762691?needAccess=true">One study</a> on climbers’ lifestyles in the US showed that the challenges of life on the road, gatherings at campgrounds and the considerable amount of time spent in nature can be enriching.</p> <p>Rock climbers’ lifestyles are inspired by and connected to natural settings. And many alternative types of tourism are too. These tourists can become powerful advocates for the protection of the places they care deeply about. Surf tourists, for example, have driven <a href="https://www.sas.org.uk/">various campaigns</a> against the discharge of sewage into UK bathing waters.</p> <p>You and those you travel with can be similar cheerleaders for the places you care about. Join organisations fighting for their conservation, contribute to their sustainable development and share your appreciation of these places with others.</p> <h2>Stay curious</h2> <p>A final thing you can do as a tourist is to keep exploring. It can be tempting to stay in a <a href="https://www.jstor.org/stable/pdf/40970087.pdf?casa_token=zGlcyUgr_JcAAAAA:TzIuU8wrbvXyjAxawpea1Nw35y-5DSZX-MShnpndR4iEwzOQqCul3Hn61SFdotC4dO3hMZ6ddpOI-O0v45K7Jwo6TY9I4FVbUaE8QMuGo7qsBFbvbXE">tourist bubble</a> and not leave the confines of your resort or stick with familiar travel groups and activities.</p> <p>Cruises are a classic example of bubble tourism.
