Fresh medical report sheds new light on Shane Warne’s sudden death

<p>New details have emerged regarding the sudden death of cricketing legend Shane Warne, who passed away in a Thai hotel room in March 2022 at the age of 52.</p> <p>A newly surfaced medical report, published by <em>The Sun</em>, reveals that multiple medications were found in Warne’s luxury villa on the Thai island of Koh Samui. These included two types of Viagra – Sildenafil (marketed as Viagra) and Kamagra (an unregulated version available in jelly sachets) – as well as Dapoxetine, a drug used to prevent premature ejaculation.</p> <p>While Viagra and Dapoxetine are legal with a prescription, Kamagra is illegal in Thailand but widely available over the counter. It remains uncertain whether Warne had taken any of these medications before his passing.</p> <p>Warne had a known history of heart issues, and these medications carry warnings for individuals with cardiovascular conditions. However, a post-mortem examination conducted in Thailand concluded that Warne died of natural causes due to congenital heart disease, ruling out foul play.</p> <p>Despite this, recent reports claim that Thai police removed Kamagra from Warne’s hotel room during their investigation. Meanwhile, News Corp reported that Warne had openly discussed using Viagra during his relationship with actress and model Elizabeth Hurley.</p> <p>Warne was staying at the Smujana Villas resort with three friends at the time of his death. CCTV footage captured two massage therapists leaving his villa shortly before he was found unresponsive at approximately 5pm His friends called for medical assistance at 5:40pm, with paramedics arriving at 6pm and initiating CPR at 6:10pm.</p> <p>Dr Dulyakit Wittayachanyapong, who oversaw Warne’s treatment at Thailand International Hospital, described his condition upon arrival, stating: “When he arrived at hospital, his face was green and pale, he had black blood in his nose and mouth, which was unusual. There was no sign of life.”</p> <p>Hospital staff attempted resuscitation for 43 minutes before Warne was declared dead at 6:53pm. According to the medical report, doctors intubated him and administered adrenaline and sodium bicarbonate in an attempt to revive him. Blood tests revealed that his oxygen levels had plummeted to a critical 40%.</p> <p>In the weeks leading up to his death, Warne had been on a liquid diet, and his lifestyle reportedly included habitual smoking and drinking.</p> <p>His sudden passing sent shockwaves through the cricketing world, with fans and former teammates mourning the loss of an icon whose impact on the sport remains unmatched.</p> <p><em>Images: Instagram</em></p>

Incredible footage emerges of plane crashing and flipping upside down

<p>Terrified passengers have recalled the moment they were left "hanging upside down like bats" after a plane crashed and flipped during an icy landing. </p> <p>The Delta Airlines plane was landing at Toronto Pearson Airport during snowy conditions, when the plane touched down and immediately caught fire. </p> <p>Skidding along the runway, the plane then flipped upside down with 80 people onboard before coming to a halt. </p> <p>Video obtained by <em>CNN</em> shows the plane landing hard on the runway, with the plane's rear landing gear buckling upon impact with the snow and erupting into a fireball. </p> <blockquote class="instagram-media" style="background: #FFF;

Supersonic jets are making a comeback – but despite the hype, don’t expect to book yet

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/chris-james-1178340">Chris James</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p>Late last week, American company Boom Supersonic flew faster than the speed of sound with its XB-1 supersonic demonstrator aircraft. It’s now the first <a href="https://boomsupersonic.com/press-release/boom-supersonic-achieves-supersonic-flight">piloted non-military aircraft to break the sound barrier</a> since the Concorde was retired from service in 2003.</p> <p>It’s the first step in Boom’s ambitious goal to have <a href="https://boomsupersonic.com/united">supersonic airliners carry passengers by 2029</a>.</p> <p>But what exactly is supersonic travel? There are good reasons why it’s not more common, despite the hype.</p> <h2>What is supersonic flight?</h2> <p>The Mach number is defined as a plane’s speed divided by the speed that sound waves move through the air. To “break the sound barrier” means to fly faster than the speed of sound, with Mach numbers greater than 1.</p> <p>The Mach number is an important ratio: as a plane flies, it disturbs the air in front of it. These disturbances move at the speed of sound. In supersonic flight these disturbances combine to form shock waves around the vehicle.</p> <p>When people say you can see a fighter jet before you hear it, they’re referring to supersonic flight: <a href="https://www.aerotime.aero/articles/top-10-worlds-fastest-fighter-jets">fighter jets can travel at around Mach 2</a>.</p> <p>The sound from the fighter jet is trapped inside its shock wave; until the shock wave moves to your position on the ground, you won’t hear the plane.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/646302/original/file-20250202-15-d01bme.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/646302/original/file-20250202-15-d01bme.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/646302/original/file-20250202-15-d01bme.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=360&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/646302/original/file-20250202-15-d01bme.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=360&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/646302/original/file-20250202-15-d01bme.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=360&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/646302/original/file-20250202-15-d01bme.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=452&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/646302/original/file-20250202-15-d01bme.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=452&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/646302/original/file-20250202-15-d01bme.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=452&amp;fit=crop&amp;dpr=3 2262w" alt="" /></a><figcaption><span class="caption">Illustration of how disturbances propagate in subsonic, Mach 1, and supersonic flow.</span> <span class="attribution"><a class="source" href="https://commons.wikimedia.org/wiki/File:Transonico-en.svg">Chabacano/Wikimedia Commons</a>, <a class="license" href="http://creativecommons.org/licenses/by-sa/4.0/">CC BY-SA</a></span></figcaption></figure> <h2>The allure of supersonic travel</h2> <p>For efficiency reasons, most passenger jets cruise slightly slower than the speed of sound, at around Mach 0.8 (this is subsonic flight).</p> <p>Boom plans to build <a href="https://boomsupersonic.com/overture">an airliner called Overture</a> that can fly at Mach 1.7. Flying supersonically can drastically decrease flight times. The company claims a trip <a href="https://boomsupersonic.com/flyby/summer-travel-trends-future-travel-onboard-overture">from New York to Rome</a> on Overture could take just four hours and 40 minutes, instead of eight hours.</p> <p>Boom isn’t the only company working on this lofty goal. American firm Spike Aerospace is also developing a supersonic business jet, <a href="https://www.spikeaerospace.com/spike-s-512-supersonic-diplomat/">with the tagline</a> “delivering the world in half the time”.</p> <p>This is the value proposition of supersonic passenger travel.</p> <p>In limited ways, it did already exist in the 20th century. However, due to timing, bad luck and the laws of physics, it didn’t continue.</p> <h2>Remember the Concorde?</h2> <p>Designs for supersonic airliners began in the mid-20th century, and by the 1970s we had supersonic passenger flight.</p> <p>There was the little-known <a href="https://en.wikipedia.org/wiki/Tupolev_Tu-144">Russian Tupolev-144</a> and <a href="https://www.britannica.com/technology/Concorde">Concorde</a>, a Franco-British supersonic airliner operated by British Airways and Air France from 1976 to 2003.</p> <p>Concorde had a capacity of <a href="https://www.heritageconcorde.com/concorde-cabin--passenger-experience">up to 128 passengers</a> and cruised at Mach 2. It regularly travelled from London to New York <a href="https://airandspace.si.edu/stories/editorial/what-happened-concordes">in around three hours</a>. The flights were expensive, mainly shuttling business people and the rich and famous.</p> <h2>Why supersonic passenger flight didn’t take off</h2> <p>Concorde was designed in the 1960s when it seemed like supersonic passenger transport was going to be the next big thing.</p> <p>Instead, the Boeing 747 <a href="https://www.boeing.com/commercial/747-8">entered commercial service in 1970</a>. Cheap, large and efficient airliners like it blew Concorde out of the water.</p> <p>Designed to cruise efficiently at supersonic speeds, Concorde was extremely fuel inefficient when taking off and accelerating. Concorde’s expensive, “<a href="https://phys.org/news/2019-03-concorde-technical-feat-financial-fiasco.html">gas guzzling</a>” nature was a complaint levelled against it for most of its lifetime.</p> <p>A catastrophic <a href="https://www.flightglobal.com/safety/tu-144-crash-puzzle-persists-50-years-after-fatal-paris-display/153782.article">1973 Paris air show crash</a> of the competing Russian airliner, Tupolev Tu-144, also shifted public perception on supersonic flight safety at a time when many airlines were considering whether or not to purchase Concordes.</p> <p><a href="https://www.heritageconcorde.com/airframe-detail">Only 20 Concordes were manufactured</a> out of the <a href="https://simpleflying.com/concorde-orders/">planned 100</a>.

In a world of remote work and video meetings, is there still a need for a supersonic airliner in the 2020s?</p> <p>For now, supersonic airliners like Overture are likely to remain in the realm of the rich and famous, like Concorde did. But with modern technological advances, it will be interesting to see whether supersonic passenger travel once again becomes reality – or even goes mainstream.

Olympic couple identified in horror plane crash

<p>Two world champion figure skaters are among dozens of casualties killed after a passenger plane carrying 64 people collided with a military Black Hawk helicopter in the US. </p> <p>The mid-air crash happened about 9pm US Eastern Time on Wednesday (1pm Thursday AEDT), when the aircrafts collided and crashed into the Potomac River near Reagan National Airport in Washington DC. </p> <p>As officials confirmed that rescue efforts had shifted to a recovery operation, two of the first victims identified were Russian Olympians and married couple Evgenia Shishkova and Vadim Naumov.</p> <p>Their son, Maxim Naumov, 23, is also feared to have been on board.</p> <p>Shishkova, 52, and Naumov, 55, won the pairs title at the 1994 world championships and competed at the Winter Olympics twice.</p> <p>It is believed the family were returning home after Maxim had been competing at the US figure skating championships in Wichita, Kansas.</p> <p>Russia’s Mash news outlet published a list of 13 skaters, many of them the children of Russian emigres to the US, who it said were believed to have been on the plane.</p> <p>Kremlin Spokesman Dmitry Peskov confirmed their death to reporter, saying, "Unfortunately, we see that this sad information is being confirmed. There were other fellow citizens there. Bad news today from Washington."</p> <p>"We are sorry and send condolences to the families and friends who lost those of our fellow citizens who died in the plane crash."</p> <p>The bodies of three US soldiers have also been recovered from the river as the recovery operations remains ongoing. </p> <p>American Airlines CEO Robert Isom said at this stage it wasn't known why the two aircrafts collided.</p> <p>"I want to express my sincere condolences for the accident that happened at DCA last night," he said.</p> <p>"We're absolutely heartbroken for the family and loved ones of the passengers and crew members, and also for those that were on the military aircraft."</p> <p>According to Jonathan Koziol, chief of staff for Army aviation, the helicopter crew "very experienced" and had flown the nighttime route countless times before. </p> <p>US President Donald Trump addressed the devastating crash in the White House, located about five kilometres away from the fatal crash site.</p> <p>"As one nation, we grieve for every precious soul that has been taken from us so suddenly," Trump said.</p> <p>"We'll find out how this disaster occurred and will ensure that nothing like this ever happens again."</p> <p><em>Image credits: Instagram </em></p>

<p>A woman has sparked a debate online after she used a Pringles tube to stop the person in front of her from reclining their seat. </p> <p>Clare Duggan shared the hack on TikTok, with the video from her plane seat showing the packet wedged securely between the top and bottom of the tray table. </p> <p>“This is the best life hack when you’ve got someone in front who is trying to put the seat down constantly,” she said. </p> <p>In just a week, the video received over 1.5 million views and received thousands of comments from TikTok users divided over the act. </p> <p>Many described it as a “brilliant” and “genius” idea, while others were less impressed, calling the act "ridiculous". </p> <p>“You know, the seats go back so people can relax,” one person commented.</p> <p>“I would never do it,” another added. </p> <p>“I’d just ask the cabin crew to see why my chair won’t recline," a third wrote. </p> <p>Some people said that while the move was "clever" all passengers were “entitled to put seat back”.</p> <div class="embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border: 0px; font-size: 16px; vertical-align: baseline; color: #323338; font-family: Figtree, Roboto, 'Noto Sans Hebrew', 'Noto Kufi Arabic', 'Noto Sans JP', sans-serif; background-color: #ffffff; outline: none !important;"><iframe class="embedly-embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border-width: 0px; border-style: initial; vertical-align: baseline; width: 535px; outline: none !important;" title="tiktok embed" src="https://cdn.embedly.com/widgets/media.html?src=https%3A%2F%2Fwww.tiktok.com%2Fembed%2Fv2%2F7461268433301261600&amp;display_name=tiktok&amp;url=https%3A%2F%2Fwww.tiktok.com%2F%40clareduggan1982%2Fvideo%2F7461268433301261600&amp;image=https%3A%2F%2Fp16-sign-useast2a.tiktokcdn.com%2Fobj%2Ftos-useast2a-p-0037-euttp%2FoAbTEBfEQ9idhI4vCo5LLnzCwSILxAPgiI8AAL%3Flk3s%3Db59d6b55%26x-expires%3D1738278000%26x-signature%3DAJXi175GcI7KVGH1AbaDNFgzBTY%253D%26shp%3Db59d6b55%26shcp%3D-&amp;type=text%2Fhtml&amp;schema=tiktok" width="340" height="700" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe></div> <p>“The seats are literally made to recline,” one person wrote. </p> <p>“I never understand why people get annoyed about a seat going back. Doesn’t bother me,” another added. </p> <p>“Quite frankly, you should be banned from flying bloody pathetic," a third wrote. </p> <p>Following the wave of comments, Duggan explained that while she doesn't mind people reclining, the passenger in front of her kept ignoring her requests to incline his seat during meal service.  </p> <p>“But this guy was refusing to lift his up when I was eating even though politely asked. So this seemed like a fair way of dealing with it,” she said.</p> <p>She added that the flight attendant had asked him to put up his seat, but he still didn't comply. </p> <p>“I always respect the person behind me by asking if they mind if I recline the seat back. That’s called consideration but I love this hack, well shared," one person commented. </p> <p><em>Image: TikTok</em></p> <p> </p>

Woman restrained and gagged on plane for "disruptive" behaviour

<p>A woman has been restrained and gagged on an international flight over her disruptive and abusive behaviour.</p> <p>Footage of the shocking moment the woman was restrained by cabin crew has been obtained by <em><a href="https://www.news.com.au/travel/travel-updates/incidents/woman-restrained-with-duct-tape-after-outburst-during-fiji-airways-flight/news-story/e088405a65c3d6ca889a0612e746702e" target="_blank" rel="noopener">news.com.au</a></em>, showing the flight attendants trying to contain the 69-year-old woman's actions. </p> <p>Police claim the woman was “intoxicated and causing a nuisance”, on the flight from San Francisco to Nadi, leading her to be arrested by Fiji police when the plane landed.</p> <p>A fellow passenger who filmed the altercation said airline staff were “forced to resort to restraining and taping the mouth” of the woman, whose comments were allegedly “racist and vulgar” in nature.</p> <p>The passenger explained that the situation unfolded about halfway into the 11-hour flight towards Nadi, after the woman started to “raise her voice” within the cabin.</p> <p>“It became known to crew and nearby passengers early into the incident that the woman was travelling with her husband, though they were sitting in different areas of the plane,” the witness, who was seated several rows away from the woman, claimed.</p> <blockquote class="instagram-media" style="background: #FFF;

Pilot explains why airplane mode on phones is so important

<p>A seasoned pilot has explained the real reason why your phone needs to be on airplane mode for the duration of your next flight. </p> <p>The pilot broke down the precaution in a video he posted to TikTok, with the explanation racking up over 2 million views. </p> <p>“The plane mode button on your phone is not a conspiracy,” declared the pilot, before reassuring passengers that using your phone onboard won't cause the plane to “fall out of the sky” or even really “mess with the systems on board”.</p> <p>However, if too many flyers choose to use their phones all at once, it can inadvertently mess with the pilots’ radio communications with the control tower.</p> <p>“If you have an aircraft with 70, 80, 150 people on board, and even three or four people’s phones start to try to make a connection to a radio tower for an incoming phone call, it sends out radio waves,” the captain explained. </p> <p>“There’s the potential that those radio waves can interfere with the radio waves of the headset that the pilots are using.”</p> <p>He recalled a recent flight where he was using his headset to get “clearance on which way to go” and the message interference made it feel like there was a “mosquito” in his ear.</p> <p>“It’s definitely not the end of the world but it’s pretty annoying when you’re trying to copy down instructions and it sounds like there’s a wasp or something flying around,” the pilot declared. </p> <p>“So if you’re ever curious why you’ve got to put on plane mode, that’s why.”</p> <p><em>Image credits: Shutterstock</em></p>

Pilot explains why plane windows are rounded

<p dir="ltr">A pilot has revealed why plane windows are the unique shape that we see today, sharing a glimpse into the world of airplane design and engineering. </p> <p dir="ltr">American Airlines pilot Captain Steve, who regularly makes TikTok videos on the marvel of flying, shared the reason why plane windows today are slightly rounded instead of square, revealing why this design became the norm. </p> <p dir="ltr">"Some of the airliners were designed with square windows and over in Europe as airplanes started to climb higher and require more pressurisation, they discovered a problem," he shared in a clip that has since been viewed over two million times.</p> <p dir="ltr">Following a series of inflight disasters caused by their rectangular counterparts, the window designs had to be changed, as Captain Steve said, “The airplanes literally came apart.”</p> <p dir="ltr">He added that "they lost a few airplanes in midair" because the square windows created "a hairline crack" right in the edge, and the stress on the airframe caused by the pressurisation was simply too much.</p> <p dir="ltr">As a result, engineers decided to round the windows' frames so they wouldn't break under the strain and they've "never had a problem since," according to the pilot.</p> <p dir="ltr">The video was flooded with comments by curious passengers, with one person writing, “I have never thought about this but it makes so much sense! Captain Steve is teaching us yet again.”</p> <p dir="ltr"><em>Image credits: Shutterstock </em></p>

Victorian plane crash victims identified

<p>Three young men have been killed after a light plane crash in eastern Victoria at around 5.45pm on Saturday. </p> <p>Pilot Luke Smith, 20, his younger brother Ben Smith, 16, and their cousin Dustin Daly, 15, were on board the plane when it crashed into a paddock and burst into flames at Tinamba West in east Gippsland. </p> <p>They were only 15 minutes into the flight, which took off from West Sale airport, when the tragic incident occurred. </p> <p>The plane was reportedly seen circling several times, with witnesses saying they heard a strange sound coming from the aircraft in the moments before the crash. </p> <p>“From accounts that I’ve seen, there may have been circling or manoeuvring to resolve that issue or to try to find somewhere to land and unfortunately, that has happened,” Aviation Projects managing director Keith Tonkin said.</p> <p>Luke Smith has held a pilot licence since 2022 and was also an instructor. His aviation consultant and flying instructor Lorraine MacGillivray has paid tribute to the three young men. </p> <p>“They were all absolutely delightful human beings, and so this is a terrible loss,” MacGillivray said.</p> <p>“The conversations I had with him, he was diligent and he was committed and he was passionate about his flying,” MacGillivray said.</p> <p>“He was also a flight instructor.”</p> <p>The brothers were also heavily involved in the Tongala football and cricket clubs, who have since offered counselling to the grieving regional community. </p> <p>The Australian Transport Safety Bureau (ATSB) is investigating the crash, with a team of investigators specialising aircraft operations and maintenance looking into what happened. </p> <p>The ATSB described the plane as "amateur-built light aircraft" and will examine the wreckage, interview witnesses and comb through flight tracking data to try and determine what went wrong. </p> <p>“We’ll start looking at the records of the plane itself, and maintenance records and pilot qualifications and the actual tasking or the nature of the flight itself,” ATSB Chief Commissioner Angus Mitchell said.</p> <p>Witnesses who saw the incident or anyone who has photos or videos of the plane have been asked to come forward. </p> <p><em>Images: 7News</em></p>

"She was the light of our lives": Family's tribute to hero kindergarten teacher

<p>Eleanor Bryant, 43, put herself in harm's way to <a href="https://www.oversixty.com.au/health/caring/heroic-kindergarten-teacher-identified-after-horror-crash" target="_blank" rel="noopener">save preschoolers</a> from a water tanker that crashed into the Macedon Ranges Montessori Pre-School in Riddells Creek on Tuesday. </p> <p>Now, the mother-of-two and speech pathologist has been remembered for her caring and down-to-earth nature by her family. </p> <p>Bryant's husband and his two young kids expressed their grief in a statement, saying they were "devastated by the loss". </p> <p>"She was the light of our lives: a cherished mother, wife, daughter and sister, and beloved by all her family and enormous network of friends," the statement read. </p> <p>"Her infectious smile, sense of humour and passion for life made her a joy to be around.</p> <p>"There is an enormous hole in our hearts today.</p> <p>"We thank the emergency services for their tireless work and the public for their beautiful tributes.</p> <p>"We will miss her like crazy. We thank you for respecting our privacy at this difficult time."</p> <p>Bryant has also been remembered for the impact she has made as a speech pathologist, with mum Becky Burton thanking her for changing her daughter Milla's life. </p> <p>"I've never met someone that was so engaging, so down to earth, so caring and would do whatever it took [to make sure Milla was happy]," Burton said.</p> <p>"[She was] the most beautiful mum and person just taken so tragically."</p> <p>Bryant tragically died at the scene after the crash, while a three-year-old boy was injured and taken to the Royal Children's Hospital with serious but non-life-threatening injuries to his arm.</p> <p>He remains in hospital and is in a stable condition. </p> <p>The driver of the truck was also taken to the Royal Melbourne Hospital in a stable condition after the "experienced 68-year-old driver is understood to have suffered a medical episode".</p> <p>Parents and family members have since visited the kindergarten and laid flowers and cards as a tribute to Bryant. </p> <p>Family friend Walter Lucas held back tears as he remembered the beloved mother-of-two, saying: "She saved that kid's life.That kid is now going to go off and live their whole life. For her to take her life for that kid, she is more than a hero.</p> <p>"She's a superhero."</p> <p>Clinton Zammit, whose children went to the kindergarten, described the situation as "really sad".</p> <p>"I feel sorry for the woman who lost her life, her kids waking up today and having no mother. An unsung hero to push away kids and not care about anything else but the kids.</p> <p>"It hits home when my kids used to come here and there are other families involved.</p> <p>"We are a close-knit community, we are small but have big hearts and this will affect the community for a while."</p> <p>The pre-school is expected to remain closed for the coming weeks, and ongoing counselling has been offered onsite.</p> <p><em>Images: Nine</em></p>

Why planes still have no smoking signs

<p dir="ltr">Have you ever wondered why planes still have dozens of no smoking signs inside an aircraft, even 30 years after a worldwide ban was implemented?</p> <p dir="ltr">A travel expert has answered this age-old question, just weeks after the US Federal Aviation Administration (FAA) got rid of the off switch for no smoking signs.</p> <p dir="ltr">This means that for all American planes across every US airline, the no smoking signs stay lit throughout the entire time you’re on board, which includes taxing, takeoff, cruising and landing.</p> <p dir="ltr">While it would seem that no smoking signs onboard planes are no longer needed nowadays, they are actually very much needed.</p> <p dir="ltr">“While no smoking signs may seem like an old and outdated practice, they are still a necessity for a few different reasons,” RVshare travel expert Maddi Bourgerie told <a href="https://www.thrillist.com/news/nation/planes-no-smoking-signs-why-expert"><em>Thrillist</em>.</a></p> <p dir="ltr">Firstly, it’s down to public health and safety, as Ms Bourgerie said, “There are aviation regulations in place that require airlines to maintain a no-smoking policy, which is largely due to the flammability of materials in the cabin.”</p> <p dir="ltr">She added, “the signs reinforce a smoke-free environment for all passengers and crew,” with second-hand smoke being dangerous to those around you in an enclosed space.</p> <p dir="ltr">Ms Bourgerie also explained that having the signs gives the airline some protection from potential lawsuits, with the signs acting as a safety net if a smoking-related incident occurs on board.</p> <p dir="ltr">The travel expert also pointed to a less obvious reason for keeping the no smoking signs, explaining, “Many procedures and protocols in aviation are maintained for consistency and familiarity.”</p> <p dir="ltr">“And the no smoking sign has become a standard part of the in-flight experience.”</p> <p dir="ltr"><em>Image credits: Shutterstock</em></p>

From eye exams to blood tests and surgery: how doctors use light to diagnose disease

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/matthew-griffith-1539353">Matthew Griffith</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>You’re not feeling well. You’ve had a pounding headache all week, dizzy spells and have vomited up your past few meals.</p> <p>You visit your GP to get some answers and sit while they shine a light in your eyes, order a blood test and request some medical imaging.</p> <p>Everything your GP just did relies on light. These are just some of the optical technologies that have had an enormous impact in how we diagnose disease.</p> <h2>1. On-the-spot tests</h2> <p>Point-of-care diagnostics allow doctors to test patients on the spot and get answers in minutes, rather than sending samples to a lab for analysis.</p> <p>The “flashlight” your GP uses to view the inside of your eye (known as an <a href="https://medlineplus.gov/ency/article/003881.htm">ophthalmoscope</a>) is a great example. This allows doctors to detect abnormal blood flow in the eye, deformations of the cornea (the outermost clear layer of the eye), or swollen optical discs (a round section at the back of the eye where the nerve link to the brain begins). Swollen discs are a sign of elevated pressure inside your head (or in the worst case, a brain tumour) that could be <a href="https://www.hopkinsmedicine.org/health/conditions-and-diseases/headache/increased-intracranial-pressure-icp-headache">causing your headaches</a>.</p> <p>The invention of <a href="https://openmedscience.com/lighting-the-way-in-healthcare-the-transformative-role-of-lasers-in-medicine/">lasers and LEDs</a> has enabled many other miniaturised technologies to be provided at the bedside or clinic rather than in the lab.</p> <p><a href="https://theconversation.com/whats-a-pulse-oximeter-should-i-buy-one-to-monitor-covid-at-home-174457">Pulse oximetry</a> is a famous example, where a clip attached to your finger reports how well your blood is oxygenated. It does this by <a href="https://www.howequipmentworks.com/pulse_oximeter/">measuring</a> the different responses of oxygenated and de-oxygenated blood to different colours of light.</p> <p>Pulse oximetry is used at hospitals (and <a href="https://theconversation.com/whats-a-pulse-oximeter-should-i-buy-one-to-monitor-covid-at-home-174457">sometimes at home</a>) to monitor your respiratory and heart health. In hospitals, it is also a valuable tool for detecting <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(12)60107-X/fulltext">heart defects in babies</a>.</p> <h2>2. Looking at molecules</h2> <p>Now, back to that blood test. Analysing a small amount of your blood can diagnose <a href="https://theconversation.com/blood-tests-and-diagnosing-illness-what-can-blood-tell-us-about-whats-happening-in-our-body-80327">many different diseases</a>.</p> <p>A machine called an automated “full blood count analyser” tests for general markers of your health. This machine directs focused beams of light through blood samples held in small glass tubes. It counts the number of blood cells, determines their specific type, and reports the level of haemoglobin (the protein in red blood cells that distributes oxygen around your body). In minutes, this machine can provide a <a href="https://www.nuffieldhealth.com/article/inside-the-pathology-lab-what-happens-to-my-blood">snapshot</a> of your overall health.</p> <p>For more specific disease markers, blood serum is separated from the heavier cells by spinning in a rotating instrument called a centrifuge. The serum is then exposed to special chemical stains and enzyme assays that change colour depending on whether specific molecules, which may be the sign of a disease, are present.</p> <p>These colour changes can’t be detected with the naked eye. However, a light beam from an instrument called a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5476943/#R88">spectrometer</a> can detect tiny amounts of these substances in the blood and determine if the biomarkers for diseases are present, and at what levels.</p> <h2>3. Medical imaging</h2> <p>Let’s re-visit those medical images your GP ordered. The development of fibre-optic technology, made famous for transforming high-speed digital communications (such as the NBN), allows light to get inside the body. The result? High-resolution optical imaging.</p> <p>A common example is an <a href="https://www.medicalnewstoday.com/articles/153737#risks-and-side-effects">endoscope</a>, where fibres with a tiny camera on the end are inserted into the body’s natural openings (such as your mouth or anus) to examine your gut or respiratory tracts.</p> <p>Surgeons can insert the same technology through tiny cuts to view the inside of the body on a video screen during <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9553337/">laparoscopic surgery</a> (also known as keyhole surgery) to diagnose and treat disease.</p> <h2>How about the future?</h2> <p>Progress in nanotechnology and a better understanding of the interactions of light with our tissues are leading to new light-based tools to help diagnose disease. These include:</p> <ul> <li> <p><a href="https://onlinelibrary.wiley.com/doi/full/10.1002/advs.201903441">nanomaterials</a> (materials on an extremely small scale, many thousands of times smaller than the width of a human hair). These are being used in next-generation sensors and new diagnostic tests</p> </li> <li> <p><a href="https://www.nature.com/articles/s41587-019-0045-y">wearable optical biosensors</a> the size of your fingernail can be included in devices such as watches, contact lenses or finger wraps. These devices allow non-invasive measurements of sweat, tears and saliva, in real time</p> </li> <li> <p>AI tools to analyse how blood serum scatters infrared light. This has allowed researchers to build a <a href="https://www.advancedsciencenews.com/powerful-diagnostic-approach-uses-light-to-detect-virtually-all-forms-of-cancer/">comprehensive database</a> of scatter patterns to detect <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/aisy.202300006">any cancer</a></p> </li> <li> <p>a type of non-invasive imaging called <a href="https://www.ncbi.nlm.nih.gov/books/NBK554044/">optical coherence tomography</a> for more detailed imaging of the eye, heart and skin</p> </li> <li> <p>fibre optic technology to deliver a tiny microscope into the body on the <a href="https://www.uwa.edu.au/projects/microscope-in-a-needle">tip of a needle</a>.</p> </li> </ul> <p>So the next time you’re at the GP and they perform (or order) some tests, chances are that at least one of those tests depend on light to help diagnose disease.<!-- Below is The Conversation's page counter tag.

How light can shift your mood and mental health

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/jacob-crouse-981668">Jacob Crouse</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/emiliana-tonini-1638957">Emiliana Tonini</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/ian-hickie-961">Ian Hickie</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>It’s spring and you’ve probably noticed a change in when the Sun rises and sets. But have you also noticed a change in your mood?</p> <p>We’ve known for a while that light plays a role in our wellbeing. Many of us tend to feel more positive when <a href="https://pubmed.ncbi.nlm.nih.gov/32925966/">spring returns</a>.</p> <p>But for others, big changes in light, such as at the start of spring, can be tough. And for many, bright light at night can be a problem. Here’s what’s going on.</p> <h2>An ancient rhythm of light and mood</h2> <p>In an <a href="https://theconversation.com/how-light-tells-you-when-to-sleep-focus-and-poo-236780">earlier article</a> in our series, we learned that light shining on the back of the eye sends “<a href="https://pubmed.ncbi.nlm.nih.gov/25451984/">timing signals</a>” to the brain and the master clock of the circadian system. This clock coordinates our daily (circadian) rhythms.</p> <p>“Clock genes” also regulate circadian rhythms. These genes control the timing of when many other genes <a href="https://pubmed.ncbi.nlm.nih.gov/31557726/">turn on and off</a> during the 24-hour, light-dark cycle.</p> <p>But how is this all linked with our mood and mental health?</p> <p>Circadian rhythms can be disrupted. This can happen if there are problems with how the body clock develops or functions, or if someone is routinely exposed to bright light at night.</p> <p>When circadian disruption happens, it increases the risk of certain <a href="https://pubmed.ncbi.nlm.nih.gov/33689801/">mental disorders</a>. These include <a href="https://www.sciencedirect.com/science/article/abs/pii/S0149763422000744">bipolar disorder</a> and <a href="https://bmcmedicine.biomedcentral.com/articles/10.1186/1741-7015-11-79">atypical depression</a> (a type of depression when someone is extra sleepy and has problems with their energy and metabolism).</p> <h2>Light on the brain</h2> <p>Light may also affect circuits <a href="https://pubmed.ncbi.nlm.nih.gov/35687680/">in the brain</a> that control mood, as <a href="https://pubmed.ncbi.nlm.nih.gov/23151476/">animal studies show</a>.</p> <p>There’s evidence this happens in humans. A brain-imaging study showed exposure to bright light in the daytime while inside the scanner <a href="https://www.cell.com/fulltext/S0960-9822(06)01758-1">changed the activity</a> of a brain region involved in mood and alertness.</p> <p>Another brain-imaging study <a href="https://pubmed.ncbi.nlm.nih.gov/22111663/">found</a> a link between daily exposure to sunlight and how the neurotransmitter (or chemical messenger) serotonin binds to receptors in the brain. We see alterations in serotonin binding in several <a href="https://pubmed.ncbi.nlm.nih.gov/33651238/">mental disorders</a>, including depression.</p> <h2>What happens when the seasons change?</h2> <p>Light can also affect mood and mental health as the seasons change. During autumn and winter, symptoms such as low mood and fatigue can develop. But often, once spring and summer come round, these symptoms go away. This is called “seasonality” or, when severe, “<a href="https://www.aafp.org/pubs/afp/issues/2020/1201/p668.html">seasonal affective disorder</a>”.</p> <p>What is less well known is that for other people, the change to spring and summer (when there is <em>more</em> light) can also come with a change in mood and mental health. Some people experience increases in energy and the drive to be active. This is positive for some but can be seriously destabilising for others. This too is an example of seasonality.</p> <p>Most people <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0239033">aren’t very seasonal</a>. But for those who are, seasonality has a <a href="https://pubmed.ncbi.nlm.nih.gov/8540777/">genetic component</a>. Relatives of people with seasonal affective disorder are more likely to also experience seasonality.</p> <p>Seasonality is also more common in conditions such as <a href="https://pubmed.ncbi.nlm.nih.gov/25063960/">bipolar disorder</a>. For many people with such conditions, the shift into shorter day-lengths during winter can trigger a depressive episode.</p> <p>Counterintuitively, the longer day-lengths in spring and summer can also destabilise people with bipolar disorder into an “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10947388/">activated</a>” state where energy and activity are in overdrive, and symptoms are harder to manage. So, seasonality can be serious.</p> <p>Alexis Hutcheon, who experiences seasonality and helped write this article, told us:</p> <blockquote> <p>[…] the season change is like preparing for battle – I never know what’s coming, and I rarely come out unscathed. I’ve experienced both hypomanic and depressive episodes triggered by the season change, but regardless of whether I’m on the ‘up’ or the ‘down’, the one constant is that I can’t sleep. To manage, I try to stick to a strict routine, tweak medication, maximise my exposure to light, and always stay tuned in to those subtle shifts in mood. It’s a time of heightened awareness and trying to stay one step ahead.</p> </blockquote> <h2>So what’s going on in the brain?</h2> <p>One explanation for what’s going on in the brain when mental health fluctuates with the change in seasons relates to the neurotransmitters serotonin and dopamine.</p> <p>Serotonin helps regulate mood and is the target of <a href="https://journals.sagepub.com/doi/full/10.1177/0706743716659417">many</a> <a href="https://pubmed.ncbi.nlm.nih.gov/38185236/">antidepressants</a>. There is some evidence of seasonal changes in serotonin levels, potentially being lower <a href="https://academic.oup.com/brain/article/139/5/1605/2468755?login=false">in</a> <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(02)11737-5/abstract?cc=y%3D">winter</a>.</p> <p>Dopamine is a neurotransmitter involved in reward, motivation and movement, and is also a target of some <a href="https://journals.sagepub.com/doi/full/10.1177/0706743716659417">antidepressants</a>. Levels of dopamine may also change with the <a href="https://www.nature.com/articles/s41398-023-02365-x">seasons</a>.</p> <p>But the neuroscience of seasonality is a developing area and more research <a href="https://www.nature.com/articles/s41398-023-02365-x">is needed</a> to know what’s going on in the brain.</p> <h2>How about bright light at night?</h2> <p>We know exposure to bright light at night (for instance, if someone is up all night) can disturb someone’s circadian rhythms.</p> <p>This type of circadian rhythm disturbance is associated with higher rates of symptoms <a href="https://www.nature.com/articles/s44220-023-00135-8">including</a> self-harm, depressive and anxiety symptoms, and lower wellbeing. It is also associated with higher rates of <a href="https://pubmed.ncbi.nlm.nih.gov/32639562/">mental disorders</a>, such as major depression, bipolar disorder, psychotic disorders and post-traumatic stress disorder (or PTSD).</p> <p>Why is this? Bright light at night confuses and destabilises the body clock. It disrupts the rhythmic regulation of mood, cognition, appetite, metabolism and <a href="https://pubmed.ncbi.nlm.nih.gov/38214638/">many</a> <a href="https://pubmed.ncbi.nlm.nih.gov/34419186/">other</a> <a href="https://pubmed.ncbi.nlm.nih.gov/33689801/">mental</a> <a href="https://pubmed.ncbi.nlm.nih.gov/36661342/">processes</a>.</p> <p>But people differ hugely in their <a href="https://www.pnas.org/doi/10.1073/pnas.1901824116">sensitivity to light</a>. While still a hypothesis, people who are most sensitive to light may be the most vulnerable to body clock disturbances caused by bright light at night, which then leads to a higher risk of mental health problems.</p> <h2>Where to from here?</h2> <p>Learning about light will help people better manage their mental health conditions.</p> <p>By encouraging people to better align their lives to the light-dark cycle (to stabilise their body clock) we may also help prevent conditions such as <a href="https://pubmed.ncbi.nlm.nih.gov/34419186/">depression</a> and <a href="https://www.sciencedirect.com/science/article/pii/S0149763422000744">bipolar disorder</a> emerging in the first place.</p> <p>Healthy light behaviours – avoiding light at night and seeking light during the day – are good for everyone. But they might be especially helpful for people <a href="https://www.sciencedirect.com/science/article/pii/S0149763422000744">at risk</a> of mental health problems. These include people with a family history of mental health problems or people who are <a href="https://pubmed.ncbi.nlm.nih.gov/38185236/">night owls</a> (late sleepers and late risers), who are more at risk of body clock disturbances.</p> <hr /> <p><em>Alexis Hutcheon has lived experience of a mental health condition and helped write this article.</em></p> <p><em>If this article has raised issues for you, or if you’re concerned about someone you know, call Lifeline on 13 11 14.</em><!-- Below is The Conversation's page counter tag.

Baggage handler reveals the best kind of luggage to travel with

<p dir="ltr">A baggage handler has revealed the best kind of suitcase you should travel with when travelling by plane.</p> <p dir="ltr">With years of experience loading planes with thousands of kinds of suitcases, a ramp agent for American Airlines has spilled the secrets on why some kinds of luggage are better than others. </p> <p dir="ltr">The worker said that while many people may gravitate towards hard-shell suitcases for extra protection, they are not the best for air travel. </p> <p dir="ltr">"Avoid plastic hard shell suitcases," the airline worker revealed on Reddit. "These are incredibly slick and prone to sliding off the bag cart while turning - taking everything on top of it with it."</p> <p dir="ltr">Instead, cloth suitcases have more friction and are "more likely to stay where we put them."</p> <p dir="ltr">He also said these days, four wheels on a suitcase is an absolute must as opposed to ones that glide on just two wheels.</p> <p dir="ltr">"If your bag has four wheels, it can simply be rolled along the floor. If it does not, it will be thrown. We don't try to slam it into anything, but it's still going to drop about 2ft (6m) over the course of its 'flight'," the crew member shared.</p> <p dir="ltr">Another thing to consider when buying your next suitcase is finding one that has handles on the side as it gives baggage handlers "far more control" over the luggage.</p> <p dir="ltr">"It's easier to get a grip with an actual handle than by grabbing a wheel," he added.</p> <p dir="ltr">The worker also said using a big bag for no reason is only going to cause the bag to collapse once it is stacked and cause a "baggage avalanche", with the same going for bags that are not "normally shaped" suitcases.</p> <p dir="ltr"><em>Image credits: Shutterstock</em></p></p>

How light tells you when to sleep, focus and poo

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/frederic-gachon-1379094">Frederic Gachon</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/benjamin-weger-1646210">Benjamin Weger</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p>Exposure to light is crucial for our physical and mental health, as this and future articles in the series will show.</p> <p>But the <em>timing</em> of that light exposure is also crucial. This tells our body to wake up in the morning, when to poo and the time of day to best focus or be alert. When we’re exposed to light also controls our body temperature, blood pressure and even chemical reactions in our body.</p> <p>But how does our body know when it’s time to do all this? And what’s light got to do with it?</p> <h2>What is the body clock, actually?</h2> <p>One of the key roles of light is to re-set our body clock, also known as the circadian clock. This works like an internal oscillator, similar to an actual clock, ticking away as you read this article.</p> <p>But rather than ticking you can hear, the body clock is a network of genes and proteins that regulate each other. This network sends signals to organs via hormones and the nervous system. These complex loops of interactions and communications have a rhythm of about 24 hours.</p> <p>In fact, we don’t have one clock, we have trillions of body clocks throughout the body. The central clock is in the hypothalamus region of the brain, and each cell in every organ has its own. These clocks work in concert to help us adapt to the daily cycle of light and dark, aligning our body’s functions with the time of day.</p> <p>However, our body clock is not precise and works to a rhythm of <em>about</em> 24 hours (24 hours 30 minutes on average). So every morning, the central clock needs to be reset, signalling the start of a new day. This is why light is so important.</p> <p>The central clock is directly connected to <a href="https://journals.sagepub.com/doi/abs/10.1177/07487304231225706">light-sensing cells</a> in our retinas (the back of the eye). This daily re-setting of the body clock with morning light is essential for ensuring our body works well, in sync with our environment.</p> <p>In parallel, <a href="https://theconversation.com/does-it-matter-what-time-of-day-i-eat-and-can-intermittent-fasting-improve-my-health-heres-what-the-science-says-203762">when we eat food</a> also plays a role in re-setting the body clock, but this time the clock in organs other than the brain, such as the liver, kidneys or the gut.</p> <p>So it’s easy to see how our daily routines are closely linked with our body clocks. And in turn, our body clocks shape how our body works at set times of the day.</p> <h2>What time of day?</h2> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=3 2262w" alt="" /></a><figcaption><span class="caption">Matt Garrow/The Conversation.</span> <span class="attribution"><a class="source" href="https://delos.com/blog/why-natural-light-is-important-for-mental-and-physical-health/">Adapted from Delos</a>, <a class="license" href="http://creativecommons.org/licenses/by/4.0/">CC BY</a></span></figcaption></figure> <h2>Let’s take a closer look at sleep</h2> <p>The naturally occurring brain hormone <a href="https://pubmed.ncbi.nlm.nih.gov/30311830/">melatonin</a> is linked to our central clock and makes us feel sleepy at certain times of day. When it’s light, our body stops making melatonin (its production is inhibited) and we are alert. Closer to bedtime, the hormone is made, then secreted, making us feel drowsy.</p> <p>Our sleep is also <a href="https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2019.00944/full">partly controlled</a> by <a href="https://www.annualreviews.org/content/journals/10.1146/annurev-genom-121222-120306">our genes</a>, which are part of our central clock. These genes influence our <a href="https://theconversation.com/does-it-matter-what-time-i-go-to-bed-198146">chronotype</a> – whether we are a “lark” (early riser), “night owl” (late sleeper) or a “dove” (somewhere in between).</p> <p>But exposure to light at night when we are supposed to be sleeping can have harmful effects. Even dim light from light pollution can impair our <a href="https://www.pnas.org/doi/10.1073/pnas.2113290119">heart rate and how we metabolise sugar</a> (glucose), may lead to <a href="https://doi.org/10.1038/s44220-023-00135-8">psychiatric disorders</a> such as depression, anxiety and bipolar disorder, and increases the overall risk of <a href="https://www.pnas.org/doi/10.1073/pnas.2405924121">premature death</a>.</p> <p>The main reason for these harmful effects is that light “at the wrong time” disturbs the body clock, and these effects are more pronounced for “night owls”.</p> <p>This “misaligned” exposure to light is also connected to the detrimental health effects we often see in people who <a href="https://theconversation.com/why-does-night-shift-increase-the-risk-of-cancer-diabetes-and-heart-disease-heres-what-we-know-so-far-190652">work night shifts</a>, such as an increased risk of cancer, diabetes and heart disease.</p> <h2>How about the gut?</h2> <p>Digestion also follows a circadian rhythm. Muscles in the colon that help move waste <a href="https://doi.org/10.1111/j.1572-0241.2004.40453.x">are more active</a> during the day and slow down at night.</p> <p>The most significant increase in colon movement starts at 6.30am. This is one of the reasons why most people feel the urge to poo <a href="https://theconversation.com/why-do-i-poo-in-the-morning-a-gut-expert-explains-229624">in the early morning</a> rather than at night.</p> <p>The gut’s day-night rhythm is a direct result of the action of the gut’s own clock and the central clock (which synchronises the gut with the rest of the body). It’s also influenced by when we eat.</p> <h2>How about focusing?</h2> <p>Our body clock also helps control our attention and alertness levels by changing how our brain functions at certain times of day. Attention and alertness levels improve in the afternoon and evening but dip during the night and early morning.</p> <p>Those fluctuations <a href="https://www.frontiersin.org/journals/molecular-neuroscience/articles/10.3389/fnmol.2012.00050/full">impact performance</a> and can lead to decreased productivity and an <a href="https://www.nature.com/articles/s41598-019-40914-x">increased risk</a> of errors and accidents during the less-alert hours.</p> <p>So it’s important to perform certain tasks that <a href="https://pubmed.ncbi.nlm.nih.gov/30923475/">require our attention</a> at certain times of day. That includes driving. In fact, disruption of the circadian clock at the start of daylight savings – when our body hasn’t had a chance to adapt to the clocks changing – <a href="https://www.sciencedirect.com/science/article/pii/S0960982219316781?via%3Dihub">increases the risk</a> of a car accident, particularly in the morning.</p> <h2>What else does our body clock control?</h2> <p>Our body clock influences many other aspects of our biology, including:</p> <ul> <li><strong>physical performance</strong> by controlling the activity of our <a href="https://doi.org/10.1038/s41574-023-00805-8">muscles</a></li> <li><strong>blood pressure</strong> by controlling the <a href="https://theconversation.com/what-time-of-day-should-i-take-my-medicine-125809">system of hormones</a> involved in regulating our blood volume and blood vessels</li> <li><strong>body temperature</strong> by controlling our metabolism and our level of physical activity</li> <li><strong>how our body handles drugs and toxins</strong> by <a href="https://doi.org/10.1080/17460441.2023.2224554">controlling enzymes</a> involved in how the liver and kidneys eliminate these substances from the body.</li> </ul> <h2>Morning light is important</h2> <p>But what does this all mean for us? Exposure to light, especially in the morning, is crucial for synchronising our circadian clock and bodily functions.</p> <p>As well as setting us up for a good night’s sleep, increased morning light exposure benefits our <a href="https://www.sciencedirect.com/science/article/pii/S0165032721008612?via%3Dihub">mental health</a> and <a href="https://academic.oup.com/jcem/article/101/9/3539/2806883">reduces the risk of obesity</a>. So boosting our exposure to morning light – for example, by going for a walk, or having breakfast outside – can directly benefit our mental and metabolic health.</p> <p>However, there are other aspects about which we have less control, including <a href="https://www.sciencedirect.com/science/article/pii/S0168952524001100">the genes</a> that control our body clock.<!-- Below is The Conversation's page counter tag.

Drunk couple forces emergency landing after mid-air meltdown

<p>A Ryanair flight to Ibiza had to be diverted after a drunk couple allegedly assaulted cabin crew and other passengers. </p> <p>The plane, carrying holiday-makers from Manchester to Ibiza had to make an emergency landing in Toulouse, where police hauled the intoxicated passengers off the plane. </p> <p>A British traveller on the flight, who asked to remain anonymous, recalled the man "swigging duty free vodka" on the first hour of the flight, before he started arguing with a male cabin crew member and punched him in the face. </p> <p>As they tried to restrain him, the intoxicated man assaulted another passenger and spat at a woman, hurling verbal abuse at her. </p> <p>“He was kicking off with everyone, he was out of control,” the witness said.</p> <p>Flight attendants reportedly warned him that the flight would have to be diverted if he didn't calm down, but he replied: “I don’t give a f***.” </p> <p>The altercation lasted for about 40 minutes until Flight FR2626 had to land in Toulouse, and 12 police officers took him away in custody. </p> <p>Video of the attack showed the man shouting and swearing at the police, before assaulting another traveller as he was being escorted off the flight. </p> <p>After he left the plane, his partner started harassing another traveller, hitting him and calling him a "paedo". </p> <p>In another video, police were filmed physically restraining the woman, before removing her from the plane. </p> <p>The flight spent just over an hour and a half on the tarmac at the Toulouse-Blagnac Airport before continuing its journey to Ibiza.</p> <p>Just last week Ryanair chief executive Michael O’Leary called for flyers to be limited to two drinks at airports to crack down on disorderly behaviour on flights. </p> <p>“We don’t want to begrudge people having a drink," he said. </p> <p>“But we don’t allow people to drink-drive, yet we keep putting them up in aircraft at 33,000ft.</p> <p>“In the old days, people who drank too much would eventually fall over or fall asleep. But now those passengers are also on tablets and powder.</p> <p>“It’s the mix. You get much more aggressive behaviour that becomes very difficult to manage.”</p> <p>The airline has started carrying out hand luggage checks to stop passengers on flights to Ibiza and the Greek islands from smuggling duty-free alcohol on-board. </p> <p>A Ryanair spokesperson has apologised for the incident saying:  “This flight from Manchester to Ibiza diverted to Toulouse after a small group of passengers became disruptive in-flight." </p> <p>“The crew called ahead for police assistance, who met the aircraft upon landing at Toulouse and offloaded two passengers before this flight continued to Ibiza.</p> <p>“We sincerely apologise to passengers for any inconvenience caused as a result of these unruly passengers’ behaviour, which was beyond Ryanair’s control. This is now a matter for local police.”</p> <p><em>Image: news.com.au</em></p>

Strangers lock toddler in plane bathroom to stop her tantrums

<p>The video of a controversial incident on a plane has caused outrage, as two women reprimanded a screaming toddler by locking her in the bathroom on the aircraft. </p> <p>On a Juneyao Airlines flight from Guiyang to Shanghai, China, in late August, a one-year-old child, who was travelling with her grandparents, reportedly sobbed non-stop during the nearly three-hour flight according to the <a href="https://nypost.com/2024/08/30/lifestyle/strangers-lock-crying-tot-in-airplane-bathroom-to-educate-her/" target="_blank" rel="noopener"><em>NY Post</em></a>. </p> <p>After being fed up with the toddler's tantrum, two women who were strangers to the family reportedly transported her to the bathroom to “educate her.”</p> <p>Shockingly, the child’s grandmother consented to the treatment.</p> <p>The punitive pair then shared the video of this alleged “potty training” on Douyin, China’s version of TikTok.</p> <p>In the clip, the women can be seen seated in the locked lavatory with the screaming infant, as one of the women is heard saying, “If you stop crying, aunty will take you back to grandma” and “We won’t let you out unless you stop crying.”</p> <p>As the girl stopped crying, the woman filming the video picked her up and told her: “If you make any noise again, we’ll come back (to the bathroom).”</p> <p>One of the women was initially proud of her cruel and unusual-seeming form of discipline, as she wrote that the tantrum was so disruptive that “many passengers were using tissues to block their ears” while others “had moved to the back of the plane to escape the noise.”</p> <p>According to a statement from the airline, the little girl's mother, who was not travelling with them, reportedly sympathised with the self-appointed aeroplane posse’s behaviour.</p> <p>Since the video went viral, and was subsequently deleted, Juneyao Airlines’ reps have since condemned the pairs’ actions and apologised for the incident and “oversight of the crew”.</p> <p>Despite the video being wiped from the social media site, many were quick to slam the behaviour of the women, saying their discipline was completely unacceptable. </p> <p>“Adults in their 30s can have emotional breakdowns, but people don’t allow toddlers to have theirs,” one person commented, </p> <p>Another wrote, “The grandmother and the two aunts should be sued, and social services should intervene. If there are parents like this, children will suffer in the future.”</p> <p>“When will these people understand that babies have the right to cry and the right to travel, they are part of society, and so are babies!!!!!!!” declared a third.</p> <p><em>Image credits: Weibo</em></p>

Passenger sparks debate over travellers sleeping in aisle seats

<p>A heated debate has erupted online after a passenger suggested those sitting in an aisle seat should remain alert and awake for the entire flight, with the only exception being if it's a long-flight of seven hours or more. </p> <p>“A person sitting in an aisle seat on a plane should not be allowed to sleep," they wrote on Reddit. </p> <p>The reason behind it, according to the passenger, is to ensure that middle and window seat passengers can access the toilet, get served by flight attendants, and evacuate quickly in an emergency. </p> <p>“There are some exceptions and those would probably be on any flight longer than seven hours.</p> <p>“But anything shorter than that, you should not be sleeping. What if the middle or window passenger needs the bathroom, or if the flight attendant needs to hand them something – You’ll be in the way.”</p> <p>They added that a snoozing aisle seat passenger could potentially slow down evacuation during an emergency and put everyone at risk. </p> <p>“Now you would be risking people’s lives because you fell asleep,” they wrote.</p> <p>Social media users flocked to the Reddit thread to share their thoughts. </p> <p> “Nah, just poke me and wake me up if you need me to get up or do something," one wrote. </p> <p>“I’m well aware that I’m in the way, believe me. I’m certainly not there because I wanted to be in the aisle seat.”</p> <p>“If you sleep in an aisle seat, you deal with people getting up. That’s the unwritten rule," another added. </p> <p>A few others supported the idea, but shared their own take on plane etiquette. </p> <p> “My take on this: if you sleep in the aisle seat, you must be okay with being woken up multiple times to let the folks in your row get up.</p> <p>“Other flight rules: middle seat gets the armrest, and window seat must raise the window shade during taxi, takeoff, and landing so the rest of us in the row can watch.”</p> <p><em>Image: Shutterstock</em></p> <p> </p>

Young Aussie medallist's sweet plane gesture

<p>Australian gold medallist Arisa Trew has warmed hearts after sharing her sweet gesture on the plane back from Paris. </p> <p>Trew became the youngest Australian to ever win a gold medal at the Paris games after emerging victorious in the skateboarding competition, capturing the hearts of Australia with her incredible performance. </p> <p>Trew was one of dozens of Aussies who <a href="https://oversixty.com.au/travel/international-travel/just-magical-aussie-olympians-return-home-in-triumph" target="_blank" rel="noopener">flew back</a> from Paris on Wednesday morning, and explained why she was quick to give up her business class seat as a medallist. </p> <p><em>Sunrise</em> host Matt Shirvington said there was a pecking order to the seat allocation on the Qantas plane, explaining, “Apparently, the breakdown is the medallists get first pick of business class, then the two-time Olympians or more get a shot at premium economy, and the rest are out the back of the plane.”</p> <p>By winning gold, Trew was allowed to be in the expensive business class seats, but she told the Jase & Lauren radio show on Nova radio that she had other plans for the lengthy flight.</p> <p>“Where did you get to sit on the plane? Because you’re a gold medallist, you’re 14 years old. Were you right up the front?” Lauren Phillips asked Trew.</p> <p>Trew’s reply stunned the radio hosts, as she admitted, “I mean, I could have been sitting in business with all the medallists, but instead I chose to sit in economy with my two best friends, Chloe and Ruby.”</p> <p>Those friends are fellow skateboarders Chloe Covell and Ruby Trew who both missed out on medals, hence their seats “out the back”.</p> <p>“You’re the cutest thing ever. We couldn’t love you anymore,” Phillips said.</p> <p>“So Arisa, does that mean you got to give someone your gold medal business class seat?”</p> <p>Trew replied, “I’m pretty sure somebody else got it because me and my friends were walking around the plane, and we went up there, and it was all full. So I definitely think somebody else was sitting there but I don’t mind.”</p> <p>Trew also revealed she was heading straight back to school after touching down in Australia and would be there bright and early on Thursday.</p> <p>“I’m gonna go back. I just love going to school, because it’s the skate park where I go to school,” she said.</p> <p>“So I get to see all my friends that skate, that I skate with every day and train with, my coaches, the teachers. Like, it’s just the best thing in the world.”</p> <p><em>Image credits: Ulrik Pedersen/CSM/Shutterstock Editorial </em></p>

Woman “bullied” on plane over budget seating trick

<p dir="ltr">A young woman has recalled a flight from hell when she was “bullied” by a couple who were trying to utilise a seating hack that went viral on TikTok. </p> <p dir="ltr">The solo traveller took to Reddit to recount the story and ask social media users if she was in the wrong for her action. </p> <p dir="ltr">The woman began by saying she usually pays more to select her plane seat ahead of time, but a medical emergency on another plane had her waiting on standby and left with no option other than to sit in a middle seat.</p> <p dir="ltr">When she was finally able to board, she was greeted by a couple who had purchased both the window and aisle seats in a bid to have more space, utilising a travel “trick” that has been popular on TikTok.</p> <p dir="ltr">The method, which has been dubbed the 'poor man's business class', usually leaves travellers with an empty middle seat and more space, and few travellers opt to pick a middle seat. </p> <p dir="ltr">“When I got to my row the man and woman were chatting and sharing a snack... it was obvious they were together. I mentioned to the man that I'm in the middle, and he got up to let me in,” the unsuspecting traveller wrote on Reddit.  </p> <p dir="ltr">“I asked them if they would prefer to sit together, I said I was totally okay with that. The woman reacted rudely to this and said ‘you're not supposed to be sitting here anyway’.”</p> <p dir="ltr">After noticing how the plane was full, she offered to show the pair her new ticket with the correct seat number on it.</p> <p dir="ltr">“She flicked her hand at my ticket and made a disgusted sound. I offered again if they wanted to sit together to which she didn't reply, her partner said it's okay and... made some small talk,” she continued. </p> <p dir="ltr">The man’s girlfriend then interrupted their conversation to ask,”'Did you use one of those third party websites to book your flight? It's so frustrating when people cheap out to inconvenience others.”</p> <p dir="ltr">The American woman explained that she had booked her flight directly and she had been placed on standby like everyone else and didn't choose the middle seat - she was assigned it.</p> <p dir="ltr">She then tried to keep the peace by refusing to engage with the furious woman.  </p> <p dir="ltr">“I was so done with her attitude, I put my headphones on and attempted to do my own thing,” she explained.</p> <p dir="ltr">But the “entitled” girlfriend wasn't letting it go, as the woman explained, “This woman kept reaching over me and tapping her partner and trying to talk to him in a way that was super intrusive.”</p> <p dir="ltr">“I could tell even her partner was trying to engage her less so that she would hopefully stop, but she didn't.”</p> <p dir="ltr">“I think they tried to pull that tactic where they don't sit together on purpose...hoping no one will sit between them. But on full flights it doesn't work. And even so - it's not the other person's fault.”</p> <p dir="ltr">The traveller's post was met with hundreds of comments slamming the girlfriend’s behaviour, as one person wrote, “It's like a toddler having a tantrum.”</p> <p dir="ltr">“She was disappointed and a total a**hole. Gross entitled people,” another added. </p> <p dir="ltr">Another person applauded the traveller’s level-headed behaviour, writing, “Wow! You are my hero for keeping it classy - I’m afraid I would not have been as kind as you.”</p> <p dir="ltr"><em>Image credits: Shutterstock </em></p>
