Tourism hotspot in Italy attracts attention for selling strange souvenir

Italy’s picturesque region of Lake Como has started selling a unique souvenir, making many people raise their eyebrows. The north Italian tourist hotspot has long been known for being the backdrop of many Hollywood films, while also hosting countless celebrity weddings, with many famous faces owning houses in the region. For those travelling to the stunning Lake Como and wanting to purchase a souvenir to remind them of their travels, you can now forgo the classic keyring or magnet for a more unique souvenir item. Communications company ItalyComunica says it has bottled the very air of Italy’s picturesque Lake Como and is selling these cans for €9.90 ($16 AUD) apiece. Each can is said to contain 400 millilitres of “100% authentic air” collected from Lake Como, with the website stating buyers can “Open it whenever you need a moment of escape, tranquillity, or simply beauty.” In an attempt to capitalise on the ever-growing visitor numbers, marketing specialist Davide Abagnale originally created the e-commerce site to sell dedicated Lake Como posters, before delving into the world of the unique souvenirs. His latest initiative of selling canned air aims to “create a souvenir that could be easily transported in a suitcase for tourists” and “something original, fun and even provocative.” Abagnale told <a href="https://edition.cnn.com/2024/11/04/travel/lake-como-air-cans-on-sale-intl-scli/index.html">CNN</a>, “It’s not a product, it’s a tangible memory that you carry in your heart,” adding that once tourists are home and have opened the can, they can repurpose it as a souvenir pen holder or plant holder. Not everyone was first onboard with the idea, as Como mayor Alessandro Rapinese said it wouldn’t be his first idea for tourists, and would prefer they take home other souvenirs, like the silk scarves the area is known for. “It’s a novel idea, but not for everyone,” he told CNN. “But as mayor of one of Italy’s most beautiful cities, if someone wants to take some of their air home, that’s fine as long as they also take beautiful memories of this area.” Image credits: ItalyComunica/CNN/Shutterstock

5 items you’re cleaning too much

Cleaning the house is no easy feat. To make life a little easier for you, here are five items you are probably cleaning more than you need to. 1. Clothes worn once For particular items of clothing such as gym gear, shirts and tights it is fine to wash clothes after every wear. However, most other items can be worn up to three times advises Carolyn Forte, the director of the Cleaning Lab at the Good Housekeeping Institute. "Over-washing and over-drying fabrics can cause fading and wear,” she said. Studies have also shown that it is ideal to wash bath towels after three uses. 2. Dinner plates Instead of spending time rinsing your plates before putting them in the dishwasher, just make sure all the food is scrapped off. "Pre-washing dishes is a waste of time and energy,” said Carolyn. "If you aren't running it right away, let the dishwasher rinse them with a 'rinse only' cycle." 3. Light Fixtures It can be tempting to dust your light fixtures every week but Carolyn advises saving your strength from a different household task. She advises that you can get away with cleaning light fixtures once a month. 4. Jackets In the cooler months jackets are worn every day. However, this necessity only needs to be washed every three months. Jackets don’t usually come into contact with skin cells or natural oils, which allows them to go longer between washes than other clothes. 5. Curtains Curtains need to be washed if you get any marks on them but if they are in pristine condition, according to Carolyn they only need to be cleaned once a year. Image credits: Shutterstock

Grave cleaning videos are going viral on TikTok. Are they honouring the dead, or exploiting them?

<a href="https://theconversation.com/profiles/edith-jennifer-hill-1018412">Edith Jennifer Hill</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> and <a href="https://theconversation.com/profiles/marina-deller-947925">Marina Deller</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> Cleaning the graves of strangers is the latest content trend taking over TikTok. But as millions tune in to watch the videos, it’s becoming clear not all of them are created equal. Two grave-cleaning creators in particular seem to reside at opposite ends of the trend. One of the first accounts to gain popularity for grave cleaning was <a href="https://www.tiktok.com/@ladytaphos">@ladytaphos</a>. This account is run by Alicia Williams, a Virginia resident who treats the graves with great dignity. Williams will often share the story of the person residing within, and acts with grace and kindness as she restores beauty to the <a href="https://www.tiktok.com/@ladytaphos/video/7197894295641148714">graves</a>. On the other end of the spectrum is Kaeli Mae McEwen, or <a href="https://www.tiktok.com/@_the_clean_girl">@the_clean_girl</a>, who leans into more clickbait-y tactics. McEwen is known for throwing a pink spiky ball through a graveyard and cleaning the grave it lands on. She also uses her videos to promote her own pink foamy cleaner (which at one point could be purchased via a link in her bio). <h2>Cleaning and death</h2> While Williams’ and McEwen’s videos may seem novel to some, death and cleaning have a long and varied relationship that spans time and cultures. Washing a loved one’s body before burial or cremation isn’t just practical – it’s a significant <a href="https://www.theage.com.au/national/victoria/washing-and-dressing-our-dead-the-movement-challenging-how-we-grieve-20230510-p5d794.html">ritual</a> that provides meaning during a period of grief. In certain cultures and religions it’s also a process of purification, or preparation for the afterlife. Much has been written about cleaning and clearing out the homes of deceased people. Family members often won’t agree on how to approach such a task. In his <a href="https://theconversation.com/friday-essay-grief-and-things-of-stone-wood-and-wool-136721">essay on death and objects</a>, author Tony Birch writes about his mother clearing out his grandmother’s house. “My mother decided that our first task after her death was to empty out her Housing Commission flat and scrub it clean,” Birch writes. He first laments the move, but later recognises the value of cleaning together before sorting – and treasuring – the items his grandmother left behind. Margaretta Magnuson’s 2017 book, <a href="https://www.google.com.au/books/edition/The_Gentle_Art_of_Swedish_Death_Cleaning/uW00DwAAQBAJ?hl=en&gbpv=1&pg=PT7&printsec=frontcover">The Gentle Art of Swedish Death Cleaning</a>, is a humorous and thoughtful introduction to the Swedish movement of döstädning. The book (and subsequent <a href="https://www.sbs.com.au/ondemand/tv-series/the-gentle-art-of-swedish-death-cleaning">reality TV series</a>) has sparked various conversations on death and cleaning, and especially on cleaning before you yourself pass away so you don’t leave a mess for your loved ones. Grave cleaning can be seen as another continuation of caring for the deceased. People who decide to clean the graves of strangers may do so out of <a href="https://www.theguardian.com/society/2022/sep/04/how-gravetok-videos-of-cleaning-headstones-went-viral">respect</a>, or in an attempt to <a href="https://www.buzzfeed.com/alexalisitza/tiktok-woman-cleans-old-gravestones">give them “their name back”</a> (as names on graves become visible following the removal of debris). <h2>Two very different approaches</h2> Williams and McEwen are received quite differently by viewers. Anecdotally, viewers respond more positively to the calmer and more respectful cleaning videos by Williams, who takes time to explain the process while ensuring the correct products are used. Meanwhile, many find McEwen’s videos problematic and criticise her for not adhering to proper graveyard decorum. McEwen makes a spectacle of sites of mourning, such as by pretending to vacuum graves, replacing flowers placed by others and making jokes. Viewers also speculate the products she uses may cause damage to the graves. Perceived intent plays a role in how each creator’s content is received. While Williams focuses on respectfully restoring graves to their former glory, McEwen positions herself as the focus and merely uses the graves for content. <h2>A complex emotional object</h2> Similar to other funerary objects such as coffins and urns, graves are associated with both the person who died and the fact of their death. As such, they are emotionally complex objects that bring both strength and sadness to those left behind. But graves are unique also in that they are private objects of grief exposed in a public context. Anyone visiting the graveyard can view and interact with them. Does that make them “fair game” for content creators? Graves don’t just represent deceased loved ones. They can also act as stand-ins in their absence, becoming stone bodies of sorts. As sociologist Margaret Gibson describes in her book <a href="https://www.mup.com.au/books/objects-of-the-dead-paperback-softback">Objects of the Dead: Mourning and Memory in Everyday Life</a>, “death reconstructs our experience of objects”. “There is the strangeness of realising that things have outlived persons, and, in this regard, the materiality of things is shown to be more permanent than the materiality of the body,” she says. Caring for and cleaning graves can therefore be interpreted as caring for the deceased, by extending their existence through the materiality of their resting place. Psychological researcher <a href="https://www.tandfonline.com/doi/abs/10.1080/1600910X.2018.1521339">Svend Brinkmann asserts</a> artefacts such as graves are “culturally sanctioned”, gaining “significance from a collective system of meaning”. In other words, we as a community create and uphold reverence for such items. This is partly why the desecration of graves is viewed as abhorrent. It is societally understood to be a desecration of the person themselves. It’s also why content creators must tread lightly. <h2>A reason for haunting?</h2> There are ways to interact with gravestones (and even create content) which acknowledge their complexity and connection to their owners. TikTok creator Rosie Grant (<a href="https://www.tiktok.com/@ghostlyarchive?lang=en">@ghostlyarchive</a>) bakes recipes found on headstones and records the process. She has even met with the families of the deceased <a href="https://www.independent.co.uk/life-style/food-and-drink/defining-dishes-ghostly-archive-tiktok-b2414122.html">to make the recipes together</a> and learn more about the people behind the engraving-worthy food. However, randomly cleaning the graves of strangers is fraught territory – and rife with potential privacy issues. It isn’t clear whether McEwen seeks permission from loved ones before cleaning graves, but contextually this seems unlikely. <a href="https://www.youtube.com/watch?v=nKkOS2GjCxk">Recent discussions</a> have also uncovered questionable editing in her videos. Some graves in her before-and-after videos have been edited to appear cleaner and to have their structure altered. McEwen’s pink foaming cleaner also appears to be a blue cleaner edited to appear pink, raising even more questions about intent and responsibility. While McEwen claims to be “honouring” lives by cleaning “final resting places”, the consensus from viewers is her actions are dishonourable. As one host <a href="https://www.youtube.com/watch?v=nKkOS2GjCxk">commented on a in podcast</a> discussing McEwen cleaning a baby’s grave while speaking in a kiddish voice: “F**k you, you’re going to get haunted.”<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/240553/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/edith-jennifer-hill-1018412">Edith Jennifer Hill</a>, Associate Lecturer, Learning & Teaching Innovation, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> and <a href="https://theconversation.com/profiles/marina-deller-947925">Marina Deller</a>, Casual Academic, Creative Writing and English Literature, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Caring

Yes, you do need to clean your tongue. Here’s how and why

<a href="https://theconversation.com/profiles/dileep-sharma-1562149">Dileep Sharma</a>, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a> Has your doctor asked you to stick out your tongue and say “aaah”? While the GP assesses your throat, they’re also checking out your tongue, which can reveal a lot about your health. The doctor will look for any changes in the tongue’s surface or how it moves. This can indicate issues in the mouth itself, as well as the state of your overall health and immunity. But there’s no need to wait for a trip to the doctor. Cleaning your tongue <a href="https://pubmed.ncbi.nlm.nih.gov/21797979/">twice a day</a> can help you check how your tongue looks and feels – and improve your breath. <h2>What does a healthy tongue look like?</h2> Our tongue plays a crucial role in eating, talking and other vital functions. It is not a single muscle but rather a muscular organ, made up of eight muscle pairs that help it move. The surface of the tongue is covered by tiny bumps that can be seen and felt, called papillae, giving it a rough surface. These are sometimes mistaken for taste buds – they’re not. Of your 200,000-300,000 papillae, only a small fraction contain taste buds. Adults have up to 10,000 taste buds and they are invisible to the naked eye, concentrated mainly on the tip, sides and back of the tongue. <figure><iframe src="https://www.youtube.com/embed/uYvpUl7li9Y?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> A healthy tongue is pink although the shade may vary from person to person, ranging from dark to light <a href="https://my.clevelandclinic.org/health/symptoms/24600-tongue-color">pink</a>. A small amount of white coating can be normal. But significant changes or discolouration may indicate a disease or <a href="https://www.healthline.com/health/tongue-problems-2">other issues</a>. <h2>How should I clean my tongue?</h2> Cleaning your tongue only takes around 10-15 seconds, but it’s is a good way to check in with your health and can easily be incorporated into your teeth brushing routine. You can clean your tongue by gently scrubbing it with a regular toothbrush. This dislodges any food debris and helps prevent microbes building up on its rough textured surface. Or you can use a special <a href="https://pubmed.ncbi.nlm.nih.gov/26865433/">tongue scraper</a>. These curved instruments are made of metal or plastic, and can be used alone or accompanied by scrubbing with your toothbrush. Your co-workers will thank you as well – cleaning your tongue can help combat <a href="https://pubmed.ncbi.nlm.nih.gov/24165218/">stinky breath</a>. Tongue scrapers are particularly <a href="https://pubmed.ncbi.nlm.nih.gov/15341360/">effective</a> at removing the bacteria that commonly causes bad breath, hidden in the tongue’s surface. <h2>What’s that stuff on my tongue?</h2> So, you’re checking your tongue during your twice-daily clean, and you notice something different. Noting these signs is the first step. If you observe any changes and they worry you, you should talk to your GP. Here’s what your tongue might be telling you. White coating Developing a white coating on the tongue’s surface is one of the <a href="https://pubmed.ncbi.nlm.nih.gov/31309703/">most common changes</a> in healthy people. This can happen if you stop brushing or scraping the tongue, even for a few days. In this case, food debris and microbes have accumulated and caused plaque. Gentle scrubbing or scraping will remove this coating. Removing microbes reduces the risk of chronic infections, which can be transferred to other organs and cause <a href="https://www.nature.com/articles/s41368-022-00163-7">serious illnesses</a>. Yellow coating This may indicate oral thrush, a <a href="https://www.nidirect.gov.uk/conditions/oral-thrush-adults">fungal infection</a> that leaves a raw surface when scrubbed. Oral thrush is <a href="https://www.aafp.org/pubs/afp/issues/2008/1001/p845.html">common</a> in elderly people who take multiple medications or have diabetes. It can also affect children and young adults after an illness, due to the temporary <a href="https://pubmed.ncbi.nlm.nih.gov/7636666/">suppression of the immune system</a> or <a href="https://www.stanfordchildrens.org/en/topic/default?id=candidiasis-in-children-90-P01888">antibiotic</a> use. If you have oral thrush, a doctor will usually prescribe a course of anti-fungal medication for at least a month. Black coating Smoking or consuming a lot of strong-coloured food and drink – such as tea and coffee, or dishes with tumeric – can cause a furry appearance. This is known as a <a href="https://my.clevelandclinic.org/health/diseases/17918-black-hairy-tongue">black hairy tongue</a>. It’s not hair, but an overgrowth of bacteria which may indicate poor oral hygiene. Pink patches Pink patches surrounded by a white border can make your tongue look like a map – this is called “<a href="https://www.mayoclinic.org/diseases-conditions/geographic-tongue/symptoms-causes/syc-20354396">geographic tongue</a>”. It’s <a href="https://www.mayoclinic.org/diseases-conditions/geographic-tongue/diagnosis-treatment/drc-20354401">not known</a> what causes this condition, which usually doesn’t require treatment. Pain and inflammation A red, sore tongue can indicate a <a href="https://medlineplus.gov/ency/article/003047.htm">range of issues</a>, including: <ul> <li>nutritional deficiencies such as folic acid or vitamin B12</li> <li>diseases including <a href="https://my.clevelandclinic.org/health/diseases/22377-pernicious-anemia">pernicious</a> anaemia, <a href="https://www.rch.org.au/kidsinfo/fact_sheets/kawasaki_disease/">Kawasaki disease</a> and <a href="https://www.childrens.health.qld.gov.au/health-a-to-z/scarlet-fever">scarlet fever</a></li> <li>inflammation known as <a href="https://www.ncbi.nlm.nih.gov/books/NBK560627/">glossitis</a></li> <li>injury from hot beverages or food</li> <li>ulcers, including cold sores and canker sores</li> <li><a href="https://www.nidcr.nih.gov/health-info/burning-mouth">burning mouth syndrome</a>.</li> </ul> Dryness Many medications can cause dry mouth, also called xerostomia. These include antidepressants, anti-psychotics, muscle relaxants, pain killers, antihistamines and diuretics. If your mouth is very dry, it may hurt. <h2>What about cancer?</h2> White or red patches on the tongue that can’t be scraped off, are long-standing or growing need to checked out by a dental professional as soon as possible, as do painless ulcers. These are at a <a href="https://oralcancerfoundation.org/cdc/premalignant-lesions/">higher risk</a> of turning into cancer, compared to other parts of the mouth. <a href="https://pubmed.ncbi.nlm.nih.gov/36852511/">Oral cancers</a> have low survival rates due to delayed detection – and they are on the rise. So <a href="https://youtu.be/Y6QkKhEjS5M">checking your tongue</a> for changes in colour, texture, sore spots or ulcers is <a href="https://www.dhsv.org.au/oral-health-programs/oral-cancer-screening-and-prevention">critical</a>.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/237130/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/dileep-sharma-1562149">Dileep Sharma</a>, Professor and Head of Discipline - Oral Health, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Drunk couple forces emergency landing after mid-air meltdown

A Ryanair flight to Ibiza had to be diverted after a drunk couple allegedly assaulted cabin crew and other passengers. 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. 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. As they tried to restrain him, the intoxicated man assaulted another passenger and spat at a woman, hurling verbal abuse at her. “He was kicking off with everyone, he was out of control,” the witness said. 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***.” The altercation lasted for about 40 minutes until Flight FR2626 had to land in Toulouse, and 12 police officers took him away in custody. 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. After he left the plane, his partner started harassing another traveller, hitting him and calling him a "paedo". In another video, police were filmed physically restraining the woman, before removing her from the plane. The flight spent just over an hour and a half on the tarmac at the Toulouse-Blagnac Airport before continuing its journey to Ibiza. 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. “We don’t want to begrudge people having a drink," he said. “But we don’t allow people to drink-drive, yet we keep putting them up in aircraft at 33,000ft. “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. “It’s the mix. You get much more aggressive behaviour that becomes very difficult to manage.” 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. 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." “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. “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.” Image: news.com.au

Flight cancelled after crew member loses it at passenger

An Air Canada flight heading from Morocco to Montreal was cancelled on Friday after a flight attendant lost it at a passenger who reportedly requested a blanket. Viral footage of the incident showed a female flight attendant yelling: “You will behave or we will get off!” at a female passenger. “I’ll tell the captain right away. Yes or no?” When a passenger asked the flight attendant to call the captain, she refused and said: “I don’t want no bullying against my crew”. She then stormed up the aisle before she turned around and yelled: “Everyone behave! Be quiet … or you’re getting off.” <blockquote class="twitter-tweet"> Stress levels are quite high in the sky these days : An Air Canada flight from Casablanca (CMN) to Montreal (YUL) was canceled due to the inappropriate behavior of a flight attendant on July 26, 2024.

In a statement to the publication, Air Canada said the flight had been rescheduled for Saturday with a different crew. “We are taking this incident very seriously. It is under review, and we will take appropriate action,” the statement read. “It is under review, and we will take appropriate action. We apologise to our customers and deeply regret that their experience today fell far short of what they have come to expect when flying with Air Canada.” The airline has also offered compensation to all passengers affected by the delay.

For a century, it’s been illegal to swim in the Seine. Will Paris’s clean-up make the river safe for Olympic swimmers?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/ian-a-wright-5162">Ian A. Wright</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a> Five eagerly anticipated events in the Paris Olympics will be the mens and womens 10 kilometre marathon swimming races, as well as the 1,500 metre swimming section of three triathlon events. Why? Because all will be held in the Seine River in the centre of Paris. The swimmers – including <a href="https://www.swimmingworldmagazine.com/news/trio-complete-an-historic-australian-olympic-marathon-swim-team-for-paris-2024">four Australians</a> – will pass famous landmarks such as the Musee d'Orsay as they swim through the historic heart of the city. This will have enormous scenic appeal for spectators. But will it be safe for swimmers? Rivers running through large cities are <a href="https://www.nature.com/articles/s42949-021-00026-w">often polluted</a>, whether from stormwater, chemical pollution or wastewater spills. As the marathon swimmers pass the <a href="https://musee-egouts.paris.fr/en/">Paris Sewer Museum</a>, they may well wonder if they’re in clean water. For more than 100 years, swimming in the Seine has actually been illegal, due to concerns over what the water could do to human health. Authorities <a href="https://www.theguardian.com/sport/article/2024/may/24/olympic-games-clean-up-aims-to-leave-parisians-swimming-in-the-seine">have been working</a> to clean up the water, spending A$2.2 billion (€1.3 billion) on improving water quality. The goal: cut bacterial contamination by 75% before the first swimmer touches the water. These measures are having an impact – but recent heavy rains have seen bacteria levels spike. While officials have put on brave faces, there’s now a <a href="https://www.reuters.com/sports/olympics/paris-2024-sets-up-reserve-site-marathon-swimming-if-seine-unsuitable-2024-07-05/">contingency plan</a> in case the Seine isn’t safe. <h2>Why swim in the Seine at all?</h2> Urban rivers have a questionable reputation. But this isn’t the first time the Seine River has been used for Olympic swimming. In the 1900 Paris Olympics, <a href="https://olympics.com/en/olympic-games/paris-1900/results/swimming">seven swimming events</a> were all held in the river. These games were the first modern Olympics where <a href="https://olympics.com/ioc/faq/history-and-origin-of-the-games/when-did-women-first-compete-in-the-olympic-games">women could compete</a> in some sports, but swimming was not one of those permitted. The Australian swimmer who competed, Frederick Lane, had to swim under the United Kingdom’s flag as Australia did not have a flag until Federation the following year. He won two gold medals. One was for the 200 metre freestyle race, and the other for a bizarre race never held again: the 200m <a href="https://www.olympedia.org/results/4433">swimming obstacle race</a>, where swimmers had to climb over poles and boats. These Olympics also saw the first and last underwater swimming race, which was also in the Seine. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/606823/original/file-20240715-17-kajph6.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/606823/original/file-20240715-17-kajph6.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/606823/original/file-20240715-17-kajph6.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=378&fit=crop&dpr=1 600w, https://images.theconversation.com/files/606823/original/file-20240715-17-kajph6.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=378&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/606823/original/file-20240715-17-kajph6.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=378&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/606823/original/file-20240715-17-kajph6.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=475&fit=crop&dpr=1 754w, https://images.theconversation.com/files/606823/original/file-20240715-17-kajph6.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=475&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/606823/original/file-20240715-17-kajph6.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=475&fit=crop&dpr=3 2262w" alt="historic photo swimming seine river paris" /></a><figcaption>Swimmers took to the Seine’s waters at the 1900 Paris Olympics, when the river ran cleaner. <a class="source" href="https://commons.wikimedia.org/wiki/File:Swimming_1900.jpg">Wikimedia Commons</a>, <a class="license" href="http://creativecommons.org/licenses/by/4.0/">CC BY</a></figcaption></figure> Back then, the waters of the Seine were cleaner. That’s because there was a great demand for human waste on farms – and cities were the main source. Back then, “night soil” (human waste) had a <a href="https://hess.copernicus.org/articles/11/1757/2007/hess-11-1757-2007.pdf">real market value</a>. No one would think of dumping it in rivers. But as time went on, sewerage systems developed and other fertilisers such as guano and mineral fertilisers arrived. By the early 20th century, most of the city’s wastewater went into the Seine. In 1923, the swimming ban came into effect. A year later, Paris hosted the Olympics for its second time – and swimmers competed in 50 metre pools. In recent years, many cities around the world have worked to clean up their urban waterways. River swimming is <a href="https://www.timeout.com/news/the-european-cities-cleaning-up-rivers-for-wild-swimmers-101821">now common</a> in cities such as Copenhagen, Berlin and Vienna, where river health has improved dramatically. <h2>How can you clean a river like the Seine?</h2> Cleaning the Seine is a challenge. Paris is home to 11 million people, with plenty of industry. Urban rivers are almost inevitably polluted by waste from the <a href="https://www.nature.com/articles/s42949-021-00026-w%5D">surrounding city</a>. Leaking and overflowing sewage systems are a major source of pollution. In places like the UK, <a href="https://www.bbc.com/news/explainers-62631320">sewage spills</a> into waterways have become a major political issue. When wastewater spills into rivers, it carries pollutants and dangerous loads of <a href="https://www.cdc.gov/mmwr/volumes/67/wr/mm6725a1.htm">disease-causing microorganisms</a>, such as Escherichia coli (commonly known as E. coli). Untreated water can have viruses, bacteria and disease-causing protozoa. In the lead-up to the Paris games, authorities have been working to improve water quality enough to bring some Olympic swimming back to the Seine. Stormwater – often contaminated by dog poo or sewage overflows – is <a href="https://www.theguardian.com/environment/2023/oct/08/can-paris-clean-seine-for-next-year-2024-olympics">being cleaned</a> before it is released into the river. Despite the money and effort, there are still real questions over whether it will be enough to guarantee swimmer safety. Bacterial levels hit risky levels <a href="https://edition.cnn.com/2024/07/11/sport/paris-olympics-seine-triathlon-bacteria-spiking-intl/index.html">most days in June</a> due to unseasonally heavy rains, but the water has <a href="https://www.france24.com/en/france/20240712-seine-clean-enough-to-swim-for-most-of-past-12-days-paris-says-ahead-of-olympics">improved in July</a>. This week, French sports minister Amélie Oudéa-Castéra <a href="https://www.nbclosangeles.com/paris-2024-summer-olympics/french-sports-minister-takes-dip-in-seine-river-2024-paris-olympics/3458469/">swam a few metres</a> in the Seine in an effort to douse concerns. By contrast, the other Olympic swimming events will take place in a recently constructed 50 metre pool, which will have very good water quality. The pool water is filtered and treated with a disinfectant such as chlorine or bromine. It will be regularly tested to ensure optimal water quality. At the Tokyo 2020 Olympics, triathletes had to swim in polluted Tokyo Bay. But similar concerns over sickness proved unfounded. The real challenge was the <a href="https://www.theguardian.com/environment/2021/aug/05/olympic-athletes-and-volunteers-in-tokyo-tortured-by-heat">oppressive heat</a>. <h2>What’s at risk?</h2> The most likely outcome if races are held when bacterial levels are unsafe would be getting a gastrointestinal bug. Officials have some control over this. Contamination is worst after heavy rain. Races could be delayed if need be. Many swimmers – especially those who compete in open-water competitions – are familiar with swimming in water with some level of pollution. Some see it as worth the risk. Italian double world champion swimmer Gregorio Paltrinieri <a href="https://www.france24.com/en/live-news/20240226-paris-holds-its-breath-for-olympic-swimming-events-in-murky-seine">said in January</a>: <blockquote> Even if the water is dirty, I would rather swim in an electric atmosphere in the centre of Paris than in an anonymous stretch of water. </blockquote> Paris 2024 organisers previously warned there was no plan B for the 10 km marathon races in the Seine if water quality testing is unsuitable. But this has now changed. If the river isn’t clean enough, open water swimming <a href="https://www.reuters.com/sports/olympics/paris-2024-sets-up-reserve-site-marathon-swimming-if-seine-unsuitable-2024-07-05/">will be moved</a> to the rowing venue. The Olympic triathlon is planned around a swimming leg in the Seine. But triathletes <a href="https://www.espn.com.au/olympics/story/_/id/39912675/triathlon-leg-cancelled-seine-quality-paris-2024-chief">have been told</a> the swim leg could be skipped if the water is unsafe, which would turn the race into a running and cycling duathlon. As the world’s attention turns to Paris, there will be many anxious officials behind the scenes hoping their hard work on making the Seine swimmable pays off.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/231705/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/ian-a-wright-5162">Ian A.

Pioneering TV presenter reveals terminal diagnosis live on air

Popular New Zealand TV presenter Joanna Paul-Robie has revealed she is dying of cancer. The pioneering presenter, known for her work on TV3, shared the heartbreaking news during an interview with Radio New Zealand on Friday morning. Paul-Robie, who has been a beloved figure in the broadcasting world, made the announcement while accepting the Icon Award for her contributions to the creative industries. “I was so touched because this award means so much to me, coming from Tauranga Moana,” she said. “But more importantly, because I am, unfortunately, dying – I have terminal cancer – and really to have this award before one posthumously gets it is an even better break. I can’t tell you the lightness, the brightness, the feeling of aroha inside me last night.” Reflecting on her career, Paul-Robie recounted her experiences as one of the few Māori individuals on New Zealand's television screens. “The newsroom was really … it was being run by mostly a pair of middle-class, middle-aged white men who had the audacity and the balls to say ‘If it bleeds, it leads’ but these guys you know they had never been in a Māori world,” she remarked. Starting her career at Radio New Zealand, Paul-Robie later became a newsreader for TV3 and played a significant role in establishing Māori Television in 2004, serving as a program and production manager. During a 2011 interview with NZOnScreen, she spoke about the challenges and triumphs of setting up the network. “There’s been a handful of people in the world who have built a television station and taken it to air,” she said. “There are only a handful of people in the world who can do that and even though it nearly broke me in half on the day that we launched, I thought ‘hell we did that’. I think it is difficult for someone like me with an A-type personality to think now you have done your big thing maybe you should take it easy now.” Paul-Robie's courage and dedication have left an indelible mark on New Zealand's broadcasting landscape. Her announcement has been met with an outpouring of support and love from colleagues, fans and the wider community, who admire her strength and resilience in the face of such a personal battle.

5 ways to fake a clean bathroom

Got a friend popping around for a catch up, and, your bathroom is less than sparkling? Don’t stress. Follow our foolproof tips to fake it so no one knows you didn’t have time to do a proper clean. 1. Scrub the loo The toilet is often a telltale sign that your bathroom is in need of a clean. If you haven’t already invested in a leave-in cleaner for your bowl, simply get in there with some toilet cleaner and give a good squirt under the rim. Leave it to do its job while you get on with the rest of the bathroom. Then when it’s had a few minutes to soak, give it a once over with the toilet brush. Grab some toilet paper (or an antibacterial wipe) and give the rim and the top of the toilet a once over to remove any dust. 2. Eliminate any obvious mould and grime Find yourself some good-quality mould spray that you can apply and then leave to work its magic while you move on to other areas of the bathroom. After 10 minutes (check your packet for the optimal time) you should be able to spray it with warm water from the shower and then wipe it clean. 3. Do a quick dust bust Grab yourself a clean cloth or antibacterial wipe and go over the shelves and basin to get rid of any dust or dirt you can see. 4.Change your bathmat and hand towel There’s nothing like a fresh and clean bathmat to trick your guests into thinking that you’ve just finished scrubbing the bathroom. Add a clean hand towel to complete the look. 5.Add a sweet scent Give your bathroom a look of freshness by popping a small vase of flowers in there. You can also try a scented candle on top of the toilet to give off a nice scent and hide any odours. Image credits: Shutterstock

Are some routes more prone to air turbulence? Will climate change make it worse? Your questions answered

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/doug-drury-1277871">Doug Drury</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a> A little bit of turbulence is a common experience for air travellers. Severe incidents are rare – but when they occur they can be deadly. The recent Singapore Airlines flight SQ321 from London to Singapore shows the danger. An <a href="https://apnews.com/article/singapore-airlines-flight-turbulence-5a9a268e1a6a6fb9ece7e58b5ea9231b">encounter with extreme turbulence</a> during normal flight left one person dead from a presumed heart attack and several others badly injured. The flight diverted to land in Bangkok so the severely injured passengers could receive hospital treatment. Air turbulence can happen anywhere, but is far more common on some routes than on others. Climate change is expected to boost the chances of air turbulence, and make it more intense. In fact, <a href="https://www.nature.com/articles/s41586-019-1465-z">some research</a> indicates turbulence <a href="https://theconversation.com/aviation-turbulence-soared-by-up-to-55-as-the-world-warmed-new-research-207574">has already worsened</a> over the past few decades. <h2>Where does turbulence happen?</h2> Nearly every flight experiences turbulence in one form or another. If an aircraft is taking off or landing behind another aircraft, the wind generated by the engine and <a href="https://www.faa.gov/air_traffic/publications/atpubs/aim_html/chap7_section_4.html">wingtips</a> of the lead aircraft can cause “wake turbulence” for the one behind. Close to ground level, there may be turbulence due to strong winds associated with weather patterns moving through the area near an airport. At higher altitudes, there may be wake turbulence again (if flying close to another aircraft), or turbulence due to updraughts or downdraughts from a thunderstorm. Another kind of turbulence that occurs at higher altitudes is harder to predict or avoid. So-called “<a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023gl103814">clear-air turbulence</a>” is invisible, as the name suggests. It is often caused by warmer air rising into cooler air, and is generally expected to get worse due to climate change. At the most basic level turbulence is the result of two or more wind events colliding and creating eddies, or swirls of <a href="https://www.nationalgeographic.com/travel/article/what-is-turbulence-explained">disrupted airflow</a>. It often occurs near mountain ranges, as wind flowing over the terrain accelerates upward. Turbulence also often occurs at the edges of the <a href="https://www.nationalgeographic.com/travel/article/what-is-turbulence-explained">jet streams</a>. These are narrow bands of strong, high-altitude winds circling the globe. Aircraft often travel in the jet streams to get a speed boost – but when entering or leaving the jet stream, there may be some turbulence as it crosses the boundary with the slower winds outside. <h2>What are the most turbulent routes?</h2> It is possible to <a href="https://turbli.com/maps/world-turbulence-map/">map turbulence patterns</a> over the whole world. Airlines use these maps to plan in advance for alternate airports or other essential contingencies. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=430&fit=crop&dpr=1 600w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=430&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=430&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=541&fit=crop&dpr=1 754w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=541&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=541&fit=crop&dpr=3 2262w" alt="Map showing air turbulence." /></a><figcaption>A map of estimated clear-air turbulence around the world, current as of 3:00PM AEST (0500 UTC) on May 22 2024. <a class="source" href="https://turbli.com/maps/world-turbulence-map/">Turbli</a></figcaption></figure> While turbulence changes with weather conditions, some regions and routes are more prone to it than others.

Weather radar imagery shows the pilots where the most intense turbulence can be expected, and they work with air traffic control to avoid those areas. When turbulence is encountered unexpectedly, the pilots immediately turn on the “fasten seatbelt” sign and reduce engine thrust to slow down the plane. They will also be in touch with air traffic control to find better conditions either by climbing or descending to smoother air. Ground-based meteorological centres can see weather patterns developing with the assistance of satellites. They provide this information to flight crews in real time, so the crew knows the weather to expect throughout their flight. This can also include areas of expected turbulence if storms develop along the intended flight route. It seems we are heading into more turbulent times. Airlines will do all they can to reduce the impact on planes and passengers.

Travel Trouble

Air travel exposes you to radiation – how much health risk comes with it?

<a href="https://theconversation.com/profiles/timothy-j-jorgensen-239253">Timothy J. Jorgensen</a>, <a href="https://theconversation.com/institutions/georgetown-university-1239">Georgetown University</a> In 2017, <a href="http://www.independent.ie/business/world/18-million-miles-and-counting-the-globes-top-business-traveller-35666790.html">business traveler Tom Stuker</a> was hailed as the world’s most frequent flyer, logging 18,000,000 miles of air travel on United Airlines over 14 years. That’s a lot of time up in the air. If Stuker’s traveling behaviors are typical of other business flyers, he may have eaten 6,500 <a href="http://www.airliners.net/forum/viewtopic.php?t=689041">inflight meals</a>, drunk 5,250 <a href="https://doi.org/10.1111/j.1708-8305.2009.00339.x">alcoholic beverages</a>, watched thousands of <a href="http://www.iata.org/publications/store/Pages/global-passenger-survey.aspx">inflight movies</a> and made around 10,000 visits to <a href="http://blog.thetravelinsider.info/2012/11/how-many-restrooms-are-enough-on-a-plane.html">airplane toilets</a>. He would also have accumulated a radiation dose equivalent to about 1,000 <a href="https://www.radiologyinfo.org/en/info.cfm?pg=safety-xray">chest x-rays</a>. But what kind of health risk does all that radiation actually pose? <h2>Cosmic rays coming at you</h2> You might guess that a frequent flyer’s radiation dose is coming from the airport security checkpoints, with their whole-body scanners and baggage x-ray machines, but you’d be wrong. The <a href="http://www.aapm.org/publicgeneral/AirportScannersPressRelease.asp">radiation doses to passengers from these security procedures</a> are trivial. The major source of radiation exposure from air travel comes from the flight itself. This is because at high altitude the <a href="http://www.altitude.org/why_less_oxygen.php">air gets thinner</a>. The farther you go from the Earth’s surface, the fewer molecules of gas there are per volume of space. Thinner air thus means fewer molecules to deflect incoming <a href="http://www.space.com/32644-cosmic-rays.html">cosmic rays</a> – radiation from outer space. With less <a href="http://www.bbc.co.uk/science/earth/atmosphere_and_climate/atmosphere">atmospheric shielding</a>, there is more exposure to radiation. The most extreme situation is for astronauts who travel entirely outside of the Earth’s atmosphere and enjoy none of its protective shielding. Consequently, they receive high radiation doses. In fact, it is the accumulation of radiation dose that is the limiting factor for the maximum length of manned space flights. Too long in space and <a href="https://www.nasa.gov/hrp/bodyinspace">astronauts risk cataracts, cancer and potential heart ailments</a> when they get back home. Indeed, it’s the radiation dose problem that is a major spoiler for <a href="http://www.space.com/34210-elon-musk-unveils-spacex-mars-colony-ship.html">Elon Musk’s goal of inhabiting Mars</a>. An extended stay on Mars, with its <a href="http://www.space.com/16903-mars-atmosphere-climate-weather.html">extremely thin atmosphere</a>, would be lethal due to the high radiation doses, notwithstanding Matt Damon’s successful Mars colonization in the movie <a href="https://www.youtube.com/watch?v=ej3ioOneTy8">“The Martian</a>.” <h2>Radiation risks of ultra frequent flying</h2> What would be Stuker’s cumulative radiation dose and what are his health risks? It depends entirely on how much time he has spent in the air. Assuming an <a href="http://hypertextbook.com/facts/2002/JobyJosekutty.shtml">average flight speed</a> (550 mph), Stuker’s 18,000,000 miles would translate into 32,727 hours (3.7 years) of flight time. The radiation dose rate at typical <a href="http://www.telegraph.co.uk/travel/travel-truths/why-do-planes-fly-so-high-feet/">commercial airline flight altitude</a> (35,000 feet) is about <a href="https://hps.org/publicinformation/ate/faqs/commercialflights.html">0.003 millisieverts per hour</a>. (As I explain in my book <a href="http://press.princeton.edu/titles/10691.html">“Strange Glow: The Story of Radiation</a>,” a millisievert or mSv is a unit of radiation dose that can be used to estimate cancer risk.) By multiplying the dose rate by the hours of flight time, we can see that Stuker has earned himself about 100 mSv of radiation dose, in addition to a lot of free airline tickets. But what does that mean for his health? The primary health threat at this dose level is an increased risk of some type of cancer later in life. Studies of atomic bomb victims, nuclear workers and medical radiation patients have <a href="https://doi.org/10.17226/11340">allowed scientists to estimate the cancer risk</a> for any particular radiation dose. All else being equal and assuming that low doses have risk levels proportionate to high doses, then an overall cancer risk rate of <a href="http://www.imagewisely.org/imaging-modalities/computed-tomography/medical-physicists/articles/how-to-understand-and-communicate-radiation-risk">0.005 percent per mSv</a> is a reasonable and commonly used estimate. Thus, Stuker’s 100-mSv dose would increase his lifetime risk of contracting a potentially fatal cancer by about 0.5 percent. <h2>Contextualizing the risk</h2> The question then becomes whether that’s a high level of risk. Your own feeling might depend on how you see your background cancer risk. Most people <a href="http://www.who.int/whr/2002/chapter3/en/index4.html">underestimate their personal risk of dying from cancer</a>. Although the exact number is debatable, it’s fair to say that <a href="https://www.cancer.org/cancer/cancer-basics/lifetime-probability-of-developing-or-dying-from-cancer.html">about 25 percent of men ultimately contract a potentially fatal cancer</a>. Stuker’s 0.5 percent cancer risk from radiation should be added to his baseline risk – so it would go from 25 percent to 25.5 percent. A cancer risk increase of that size is too small to actually measure in any scientific way, so it must remain a theoretical increase in risk. A 0.5 percent increase in risk is the same as one chance in 200 of getting cancer. In other words, if 200 male travelers logged 18,000,000 miles of air travel, like Stuker did, we might expect just one of them to contract a cancer thanks to his flight time. The other 199 travelers would suffer no health effects. So the chances that Stuker is the specific 18-million-mile traveler who would be so unlucky is quite small. Stuker was logging more air hours per year (greater than 2,000) than most pilots typically log (<a href="http://work.chron.com/duty-limitations-faa-pilot-17646.html">under 1,000</a>). So these airline workers would have risk levels proportionately lower than Stuker’s. But what about you? If you want to know your personal cancer risk from flying, estimate all of your commercial airline miles over the years. Assuming that the values and parameters for speed, radiation dose and risk stated above for Stuker are also true for you, dividing your total miles by 3,700,000,000 will give your approximate odds of getting cancer from your flying time. For example, let’s pretend that you have a mathematically convenient 370,000 total flying miles. That would mean 370,000 miles divided by 3,700,000,000, which comes out to be 1/10,000 odds of contracting cancer (or a 0.01 percent increase in risk). Most people do not fly 370,000 miles (equal to 150 flights from Los Angeles to New York) within their lifetimes. So for the average flyer, the increased risk is far less than 0.01 percent. To make your exercise complete, make a list of all the benefits that you’ve derived from your air travel over your lifetime (job opportunities, vacation travel, family visits and so on) and go back and look at your increased cancer risk again. If you think your benefits have been meager compared to your elevated cancer risk, maybe its time to rethink flying. But for many people today, flying is a necessity of life, and the small elevated cancer risk is worth the price.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/78790/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/timothy-j-jorgensen-239253">Timothy J.

Love is in the air! Pilot proposes to flight attendant girlfriend before take off

A pilot has proposed to his flight attendant girlfriend just minutes before take off in a heart-warming display of love. Polish pilot Konrad Hanc was captured emerging from the cockpit before embarking on a flight to Kraków to make a surprising announcement over the PA system. Hanc introduced himself to the passengers before explaining the real reason for his message. “On today’s flight there is a very special person," he began. “Ladies and gentlemen, about one and a half years ago in this job I met the most wonderful person that completely changed my life." “You are most precious to me. You are my greatest dream come true. This is why I have to ask you a favour, honey." <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-permalink="https://www.instagram.com/reel/C6EHHyQskLc/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/C6EHHyQskLc/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by LOT Polish Airlines (@flylot)</a> </div> </blockquote> “Will you marry me?” he asked while getting down on one knee, as another flight attendant handed him a bouquet of flowers.

“Love is so sweet": Man's sweet mid-air proposal goes viral

Love is in the air! A smitten passenger took his love to the skies and proposed to his girlfriend while on board an Air Peace flight, with the romantic moment captured on camera. A social media user took to TikTok to share the sweet proposal, with the caption: “POV: My friend was proposed to in a plane.” The minute-long video showed a man getting out of his seat on board the packed plane to use the aircraft’s PA system so that he could ask for his girlfriend’s hand in marriage. “She’s so precious and her name is Precious,” the man said before popping the question. “Please, my Precious, I want to ask, will you marry me?” “If you will, just come out and say ‘yes’ to me, my precious,” he added before walking down the aisle of the aircraft. Other passengers cheered for the couple, and in a second video, the man is seen greeting Precious, then getting down on one knee to offer her the ring. Precious was overjoyed at the proposal and said yes, hugging her new fiance. While it is unclear where the plane was travelling, Air Peace is a Nigerian carrier that operates flights to destinations in West Africa and the Middle East, according to the NY Post. TikTok users were also touched by the romantic act, with many of them congratulating the couple. “This is beautiful,” one wrote. “Love is so sweet for real,” another swooned. Images: TikTok

Vinegar and baking soda: a cleaning hack or just a bunch of fizz?

<a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> Vinegar and baking soda are staples in the kitchen. Many of us have combined them in childhood scientific experiments: think fizzy volcanoes and geysers. But people also frequently mix vinegar and baking soda to produce a reportedly effective household cleaner. Unfortunately, the chemistry behind the bubbly reaction doesn’t support the cleaning hype. The fizzy action is essentially <a href="https://theconversation.com/six-surprising-things-about-placebos-everyone-should-know-220829">a visual “placebo</a>”, formed by the combination of an acid and a base. So, how does it work, and is it worth using these chemicals for cleaning? To understand all this, it helps to know a little more about chemistry. <h2>What’s an acid?</h2> Foods with a sour taste typically contain acids. These include citric acid in lemon juice, malic acid in apples, lactic acid in yoghurt and <a href="https://theconversation.com/kitchen-science-everything-you-eat-is-made-of-chemicals-56583">phosphoric acids in soft drinks</a>. Most vinegars contain around 4–10% acetic acid, the rest is water and small amounts of flavour chemicals. There are other naturally occurring acids, such as formic acid in ant bites and hydrochloric acid in our stomachs. Industrially, sulfuric acid is used in mineral processing, nitric acid for <a href="https://theconversation.com/what-is-ammonium-nitrate-the-chemical-that-exploded-in-beirut-143979">fertiliser manufacturing</a> and the highly potent hydrofluoric acid is used to etch glass. All of these acids share similar properties. They can all release hydrogen ions (positively charged atoms) into water. Depending on their potency, acids can also dissolve minerals and metals through various chemical reactions. This is why vinegar is an excellent cleaner for showers or kettles – it can react with and dissolve mineral deposits like limescale. Other common acidic cleaning ingredients are oxalic acid, used for revitalising timber decks, hydrochloric acid in concrete and masonry cleaners, and sulfamic acid in potent toilet cleaners. <h2>What’s a base?</h2> In chemistry, bases – the opposite of acids in many ways – can bind, rather than release hydrogen ions. This can help lift and dissolve insoluble grime into water. Bases can also break apart fat molecules. Baking soda (also known as sodium hydrogen carbonate, sodium bicarbonate, or bicarb) is a relatively weak base. Stronger common bases include sodium carbonate (washing soda), sodium hydroxide (lye) and ammonia. <a href="https://theconversation.com/spill-at-a-nuclear-facility-shows-potential-burn-risks-from-a-household-chemical-112763">Sodium hydroxide</a> is a potent drain cleaner – its strong base properties can dissolve fats and hair. This allows blockages to be broken down and easily flushed away. <h2>Mixing a base and an acid</h2> Mixing vinegar and baking soda causes an immediate chemical reaction. This reaction forms water, sodium acetate (a salt) and carbon dioxide – the fizzy part. The amount of carbon dioxide gas that is produced from baking soda is remarkable – one tablespoon (around 18 grams) can release over <a href="https://www.chemedx.org/JCESoft/jcesoftSubscriber/CCA/CCA8/MAIN/8/06/2/4/movie.html">five litres of gas</a>! But only if you add enough acid. Reactions in chemistry often use equal quantities of chemical reagents. A perfect balance of acetic acid and baking soda would give you just water, carbon dioxide and sodium acetate. But the majority of vinegar and bicarb cleaner recipes use a large excess of one or the other components. An example from TikTok for a DIY oven cleaner calls for one and a half cups of baking soda and one quarter cup of vinegar. Crunching the numbers behind the chemical reaction shows that after the fizz subsides, over 99% of the added baking soda remains. So the active cleaning agent here is actually the baking soda (and the “elbow grease” of scrubbing). Ovens can be cleaned much more rigorously with stronger, sodium hydroxide based cleaners (although these are also more caustic). Many modern ovens also have a self-cleaning feature, so read your product manual before reaching for a chemical cleaner of any sort. <h2>What about the sodium acetate?</h2> Devotees of vinegar and baking soda mixtures might be wondering if the product of the fizzy reaction, sodium acetate, is the undercover cleaning agent. Unfortunately, sodium acetate is an even weaker base than baking soda, so it doesn’t do much to clean the surface you’re trying to scrub. Sodium acetate is used in <a href="https://www.youtube.com/watch?v=vABpel-11Nc">crystallisation-based heating packs</a> and as a concrete sealant, but not typically as a cleaner. Fun fact: sodium acetate can be combined with acetic acid to make a crystalline <a href="https://theconversation.com/busting-the-myth-that-all-food-additives-are-bad-a-quick-guide-for-label-readers-82883">food additive</a> called sodium diacetate. These crystals give the vinegar flavour to <a href="https://www.youtube.com/watch?v=N0hEutu_goY">salt and vinegar chips</a> without making them soggy. <h2>Sorry to burst your bubbles</h2> There are a few rare cases where mixing vinegar and baking soda may be useful for cleaning. This is where the bubbling has a mechanical effect, such as in a blocked drain. But in most cases you’ll want to use either vinegar or baking soda by itself, depending on what you’re trying to clean. It will be less <a href="https://theconversation.com/visually-striking-science-experiments-at-school-can-be-fun-inspiring-and-safe-banning-is-not-the-answer-195362">visually exciting</a>, but it should get the job done. Lastly, remember that mixing cleaning chemicals at home can be risky. Always carefully read the product label and directions before engaging in DIY concoctions. And, to be extra sure, you can find out more safety information by reading the product’s <a href="https://theconversation.com/a-new-tiktok-trend-has-people-drinking-toxic-borax-an-expert-explains-the-risks-and-how-to-read-product-labels-210278">safety data sheet</a>.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/225177/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, Senior Lecturer in Chemistry, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Longing for the ‘golden age’ of air travel? Be careful what you wish for

<a href="https://theconversation.com/profiles/janet-bednarek-144872">Janet Bednarek</a>, <a href="https://theconversation.com/institutions/university-of-dayton-1726">University of Dayton</a> Long lines at security checkpoints, tiny plastic cups of soda, small bags of pretzels, planes filled to capacity, fees attached to every amenity – all reflect the realities of 21st century commercial air travel. It’s no wonder that many travelers have become nostalgic for the so-called “golden age” of air travel in the United States. During the 1950s, airlines promoted commercial air travel as glamorous: stewardesses served full meals on real china, airline seats were large (and frequently empty) with ample leg-room, and passengers always dressed well. After jets were introduced in the late 1950s, passengers could travel to even the most distant locations at speeds unimaginable a mere decade before. An airline trip from New York to London that could take up to 15 hours in the early 1950s could be made in less than seven hours by the early 1960s. But airline nostalgia can be tricky, and “golden ages” are seldom as idyllic as they seem. Until the introduction of jets in 1958, most of the nation’s commercial planes were propeller-driven aircraft, like the DC-4. Most of these planes were unpressurized, and with a maximum cruising altitude of 10,000 to 12,000 feet, they were unable to fly over bad weather. Delays were frequent, turbulence common, and air sickness bags often needed. Some planes were spacious and pressurized: the <a href="http://everythingnice.org/wp-content/uploads/2009/07/PanAm-cutawayS.jpg">Boeing Stratocruiser</a>, for example, could seat 50 first class passengers or 81 coach passengers compared to the DC-3’s 21 passengers. It could cruise at 32,000 feet, which allowed Stratocruiser to fly above most bad weather it encountered. But only 56 of these planes were ever in service. While the later DC-6 and DC-7 were pressurized, they still flew much lower than the soon-to-appear jets – 20,000 feet compared to 30,000 feet – and often encountered turbulence. The piston engines were bulky, complex and difficult to maintain, which contributed to frequent delays. For much of this period, the old saying “Time to spare, go by air” still rang true. Through the 1930s and into the 1940s, almost everyone flew first class. Airlines did encourage more people to fly in the 1950s and 1960s by introducing coach or tourist fares, but the savings were relative: less expensive than first class, but still pricey. In 1955, for example, so-called “bargain fares” from New York to Paris were the equivalent of just over $2,600 in 2014 dollars. Although the advent of jets did result in lower fares, the cost was still out of reach of most Americans. The most likely frequent flier was a white, male businessman traveling on his company’s expense account, and in the 1960s, airlines – with young attractive stewardesses in short skirts – clearly catered to their most frequent flyers. The demographics of travelers did begin to shift during this period. More women, more young people, and retirees began to fly; still, airline travel remained financially out-of-reach for most. If it was a golden age, it only was for the very few. <figure><iframe src="https://www.youtube.com/embed/bKqQgNZylLw?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Jet planes were introduced in the late 1950s, resulting in shorter flight times. But their ticket prices out of reach for the average traveler.</figcaption></figure> People also forget that well into the 1960s, air travel was far more dangerous than it is today. In the 1950s and 1960s US airlines experienced at least a half dozen crashes per year – most leading to fatalities of all on board. People today may bemoan the crowded airplanes and lack of on-board amenities, but the number of fatalities per million miles flown has dropped dramatically since since the late 1970s, especially compared to the 1960s. Through at least the 1970s, airports even prominently featured kiosks selling flight insurance. And we can’t forget hijackings. By the mid-1960s so many airplanes had been hijacked that <a href="http://www.latinamericanstudies.org/hijackers/flying-high.htm">“Take me to Cuba”</a> became a punch line for stand-up comics. In 1971 <a href="http://nymag.com/news/features/39593/index2.html">D.B. Cooper</a> – a hijacker who parachuted from a Boeing 727 after extorting $200,000 – might have been able to achieve folk hero status. But one reason US airline passengers today (generally) tolerate security checkpoints is that they want some kind of assurance that their aircraft will remain safe. And if the previous examples don’t dull the sheen of air travel’s “golden age,” remember: in-flight smoking was both permitted and encouraged.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/34177/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/janet-bednarek-144872">Janet Bednarek</a>, Professor of History, <a href="https://theconversation.com/institutions/university-of-dayton-1726">University of Dayton</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

9 tricky ways to clean your house while you sleep

1. Soak a showerhead Mineral deposits can clog a showerhead and affect its pressure over time. To clean, fill a plastic bag with vinegar. Place the bag around the showerhead, submerging it in the liquid. Secure the bag to the neck of the showerhead with a twist tie and leave overnight. The vinegar will break down the buildup by morning. 2. Remove stains on pots and pans If a batch of cookies left your baking sheet gunky, let a dryer sheet clean it overnight. Place the sheet on the pan and fill with warm water. Cleaning agents in the dryer sheet will help loosen stuck-on grime and stains. In the morning, easily wipe off with a sponge. 3. Polish stove grates Cleaning greasy, food-splattered stove burners can be a tiresome chore. Before you go to bed, seal each burner in a large plastic bag with ¼ cup of ammonia. The overnight soak will make it easy to wipe off the surface with a sponge the following day. 4. Banish rust on tools If your rusty tools have seen better days, fill a tray with Coca-Cola. Submerge the tools, allow to soak overnight, and scrub clean with a stiff brush in the morning. The soda’s phosphoric acid will help loosen the gunk. 5. Eliminate wet messes If your sofa or carpet became the victim of an icky, wet mess (say, vomit or urine), mix a paste of baking soda and water to soak it up. Use a spoon to spread the paste over the soiled area. Allow to dry overnight, then vacuum in the morning. 6. Descale a kettle Limescale can build up from calcium carbonate deposits in water, leading to an off-white, chalky deposit in your kettle. To clean, cut a lemon into large slices, place in the kettle, and add water. Bring to a boil, then take the kettle off the heat and leave overnight. The lemon’s citric acid will loosen the limescale. Toss the fruit and water mixture in the morning and rinse before using your newly cleaned kettle. 7. Clean bath toys To make grubby rubber duckies, boats, and other bath toys new again, mix one gallon warm water with ¾ cup vinegar. Soak the toys overnight. Rinse thoroughly and allow to air dry. 8. Make diamonds sparkle Quickly polish a diamond ring by filling a bottle cap with Windex. Soak the ring overnight and dry with a soft cloth in the morning to remove grime and add shine. 9. Remove red wine stains If red wine marked up your favorite garment, sprinkle the stain with salt and cover with club soda. The salt absorbs the stain while the club soda’s carbonation and sodium helps lift it. Leave overnight before laundering.

Air travel is in a rut – is there any hope of recapturing the romance of flying?

<a href="https://theconversation.com/profiles/christopher-schaberg-1451119">Christopher Schaberg</a>, <a href="https://theconversation.com/institutions/arts-and-sciences-at-washington-university-in-st-louis-5659">Arts & Sciences at Washington University in St. Louis</a> Amelia Earhart broke a transcontinental speed record 90 years ago, in July 1933, by flying <a href="https://airandspace.si.edu/multimedia-gallery/web11183-2009640jpg">her signature red Lockheed Vega</a> from Los Angeles to New Jersey in just 17 hours, seven and a half minutes. Earlier that year, Earhart had flown as an observer on a Northwest Airways winter flight across the U.S., testing the possibilities of a “Northern Transcontinental” route. Because those early airplanes couldn’t reach high altitudes, they weaved through dangerous peaks and the erratic weather patterns that mountain ranges helped create. One co-pilot <a href="https://www.deltamuseum.org/about-us/blog/from-the-hangars/2019/07/24/delta-stories-amelia-earhart">remembers the journey</a> as “seat-of-the-pants flying across the Dakota and Montana plains and through, over and around the Western mountain ranges.” How does air travel today compare? I’ve studied <a href="https://www.theatlantic.com/technology/archive/2018/02/engine-failure/552959/">airplane technology</a>, <a href="https://www.theatlantic.com/technology/archive/2013/09/a-forgettable-passage-to-flight/279346/">airport design</a> and <a href="https://www.upress.umn.edu/book-division/books/grounded">cultural attitudes</a> toward air travel, and I’ve noticed how aspects of flying seem to have calcified over time. Long-distance flight <a href="https://theconversation.com/longing-for-the-golden-age-of-air-travel-be-careful-what-you-wish-for-34177">advanced rapidly between the 1930s and the early 1960s</a>, shaving off the number of hours in the sky by half. But over the past 60 years, the duration of such flights has remained roughly the same. Meanwhile, the ecosystem of air travel has grown more elaborate, often leaving passengers squirming in their seats on the tarmac before or after flight. Coast-to-coast air travel is in a rut – but there are still efforts to improve this mode of transit. <h2>Just another ordinary miracle</h2> Transcontinental air journeys are clearly different 90 years after Earhart’s record-breaking exploratory flights: Travelers now take such trips for granted, and often find them to be pure drudgery. In 2018, <a href="https://thepointsguy.com/reviews/united-757-200-first-class-ewr-sea/">travel blogger Ravi Ghelani reviewed in minute detail</a> a United Airlines flight from Newark, New Jersey, to Seattle – roughly the same northern route that Earhart explored in 1933. But for Ghelani, seated in first class, it wasn’t the terrain or frigid temperatures that were the most cumbersome part of his adventure. It was a cheap complimentary blanket, which “barely qualified as one – it was very thin, very scratchy.” The dreaded blanket reappears in Ghelani’s summary of his trip: “My main qualm with this flight was the lack of a decent blanket – the tiny, scratchy blanket that was provided wasn’t cutting it for the six-hour flight.” I can imagine Earhart rolling in <a href="https://airandspace.si.edu/stories/editorial/legend-amelia-earharts-disappearance">her watery grave</a>: “You zip across the continent in six hours and you complain about a scratchy blanket?” Yet Ghelani’s account of a mundane cross-country flight reveals a truth: Commercial air travel just isn’t the adventure it was back in Earhart’s time. As one captain of a major U.S. airline who regularly flies long routes told me, “Today jetliners fly across the country from Los Angeles to New York, or Boston to Seattle, full of passengers oblivious to the commonplace practice it has become.” This pilot compared coast-to-coast flights to “iPhones, microwaves or automobiles” – just one more ordinary miracle of modern life. <h2>Little indignities multiply</h2> The high-risk adventure of air travel has been subdued, yet long flights today can paradoxically feel torturous. As philosopher Michael Marder puts it in his 2022 book “<a href="https://mitpress.mit.edu/9780262543712/philosophy-for-passengers/">Philosophy for Passengers</a>”: “When crew members wish passengers a ‘pleasant journey,’ I hear a dash of cruel irony in their words. How pleasant can the passenger experience be when you are crammed in your seat, with little fresh air, too hot or miserably cold, and sleep deprived?” I asked my colleague and <a href="http://airplanereading.org/story/55/frequent-flight">frequent flier</a> Ian Bogost about his experience of coast-to-coast trips, and his reply was illuminating: “The same trip seems to get longer every year, and less comfortable. There are reasons – consolidation, reduced routes, pilot and air-traffic labor shortages, decaying technical infrastructure – but it still feels like moving backwards.” In spite of widespread attempts to update aircraft and modernize terminals, the vast system of air travel can seem cumbersome and outdated. Recently at The Atlantic, reporter <a href="https://www.theatlantic.com/technology/archive/2023/07/clear-airport-security-lines-tsa-infrastructure/674809/">Amanda Mull wrote about</a> the biometric screening company Clear, describing this firm’s high-tech service to skip the ubiquitous toil of identity checks before flight, at the cost of surrendering some privacy and personal information. Mull concludes the reason more travelers will likely enroll in this service is that “traversing American airport security is simply that grim.” For Mull, the adventure of contemporary air travel isn’t the destination, or even the journey itself – it’s what you must do to get through the airport. Still, it’s worth noting that the majority of the human population has never boarded an airplane; flying cross-country remains <a href="https://www.smithsonianmag.com/air-space-magazine/how-much-worlds-population-has-flown-airplane-180957719/">a relatively exclusive experience</a>. For most people, the closest they’ll get to a coast-to-coast flight is seeing a small white scratch across the sky, as another airliner makes its arc at 35,000 feet. <h2>2 futures of cross-country flight</h2> Coast-to-coast travel is no longer about breakneck speed or defying elemental odds, and Earhart’s quests to push the limits of aviation couldn’t be further from the bland routines of contemporary air travel. Nor does it involve people dressing to the hilt to step aboard a jetliner for the first time, with passengers stowing their fancy hats in spacious overhead bins. Where are the new frontiers for transcontinental flight today? One area of innovation is in a greener form of flight. Solar Impulse, a completely solar-powered plane, took two months to fly coast-to-coast in 2013. It averages a plodding 45 mph at cruising altitude. As <a href="https://apnews.com/ded34ccc19f24aeea67ba3da130a2be0">The Associated Press reported</a>: “Solar Impulse’s creators view themselves as green pioneers – promoting lighter materials, solar-powered batteries, and conservation as sexy and adventurous. Theirs is the high-flying equivalent of the Tesla electric sports car.” Solar Impulse was more recently <a href="https://aviationweek.com/aerospace/aircraft-propulsion/solar-powered-skydweller-completes-first-autonomous-flights?check_logged_in=1">reconfigured as a remotely piloted aircraft</a>, with new experiments in long-distance solar flight underway. The comparison of Solar Impulse to a Tesla is handy because a different extreme can be found in Elon Musk’s company SpaceX. As part of the relentless development of its biggest vehicle, “Starship,” SpaceX has advertised the possibility of “<a href="https://www.spacex.com/human-spaceflight/earth/">point-to-point</a>” travel on Earth: for example, flying on a commercial rocket from Los Angeles to New York in 25 minutes. Never mind the physical tolls of a normal <a href="https://theconversation.com/why-would-anyone-want-to-sit-on-a-plane-for-over-18-hours-an-economist-takes-the-worlds-longest-flight-122433">19-hour flight</a>; it’s hard to imagine what such a brief yet fast trip would feel like, not to mention what sort of class divisions and bleak industrial launch sites such jaunts would rely on. Get there as fast as possible, using as much fuel as necessary; or glide lazily along, powered by the sun, saving the planet. These are two starkly different visions of coast-to-coast flight, one a dystopian nightmare and the other a utopian dream. In the middle, there’s what most flying mortals do: wait in lines, board unceremoniously and be relieved if you get to your destination without too much discomfort or delay.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/210778/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/christopher-schaberg-1451119">Christopher Schaberg</a>, Director of Public Scholarship, <a href="https://theconversation.com/institutions/arts-and-sciences-at-washington-university-in-st-louis-5659">Arts & Sciences at Washington University in St. Louis</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Outrage after renters confronted with cleaning “scoring system”

An Australian real estate agent has come under fire for their “demoralising” scoring system for tenants during routine inspections. One fired up renter said they were shocked to receive a scorecard from the agent after they complied with an inspection, and shared their feedback on Reddit. The scorecard rated the tenant’s efforts cleaning the property in 17 different rooms and areas, marking them on cleanliness, and if the areas were damaged or required maintenance. The renter was then also given an overall rating out of five stars, based on the upkeep of their rental home. The Reddit user showed that they received just three and half stars, despite being marked down in only one area due to a light globe not working. In their post, the tenant said they had made every effort to clean the home, adding that the rating was “demoralising”. “I’ve been renting a long time, and my deep cleaning routine is based around inspections,” they explained. “I go all out - every room in my little 3x2 villa is given a spring clean, every surface is washed including walls, doors, lights, windows, carpets etc.” “Had my latest inspection a few weeks ago and just received the report. Despite the agent commenting once again that she never sees houses as clean as mine, and taking 112 (!) photos of every single thing that shows how great the condition of the house is - having one light globe not working is so terrible that I’m scored three and a half out of five.” The renter went on to say that they had only recently discovered that the broken light globe was the real estate’s responsibility to replace, and does not warrant such a severe marking down in their “score”. “The globe in question is a downlight fitting. We have so many downlights that I don’t even use this particular one,” they continued. “I can’t replace the globe itself, I need to get into the roof to replace the whole unit. Thanks to people here I’ve learned this isn’t even my responsibility to fix!” The renter’s post sparked a huge outrage online, with many up in arms over the current state of the rental market and unrealistic expectations of estate agents. One person said, “I fully believe that the average renter keeps a home to a higher standard than an owner, and it seems deliberately demoralising that someone could be marked down for having a light out.” Another added, “This is ridiculously petty, and more importantly, totally irrelevant to the purpose of a periodic inspection. Which is to identify whether any maintenance is needed.” A third person took their anger out on the entire system, summing it up by writing, “I sort of wonder what little lightbulb clicks in your mind and you wake up one day and ask yourself, ‘How can I be a massive c*** who offers no value to society? I know! I will get into real estate.’” Image credits: Getty Images / Reddit

Doctor debunks air fryer myth

Air fryers have become somewhat of a commodity in many kitchens worldwide, with them rising in popularity over the past few years, so news that they could be damaging to our health may cause quite a stir. However, similar to how uncredited information seems to circle the internet, a doctor has told viewers not to take the latest warnings over “toxic” air fryers too seriously. One online user posted a TikTok claiming they had found out "air fryers were toxic because of the material used”, so UK doctor Karan Raj decided to weigh in on the matter. "The biggest worry from fear mongers centres around the non-stick materials used, also known as forever chemicals,” he said in a clip that’s since raked in over a million views. "Forever chemicals” earned the name because they don’t break down in the environment or in our bodies. Also known as PFAS, they are resistant to water, grease, and heat and are found in a number of everyday products such as food packaging, cosmetics, clothing and toilet paper. "Fun fact, every time you sit down to eat microplastics fall from the air and land in your food, or are already part of your food," he explained. The issue of “toxic” chemicals leeching into your food from cooking in an air fryer "is only really an issue if the air fryer is damaged,” Dr Raj added. It is recommended to minimise how much damage and scratching there is to the non-stick coating of the fryer so the chemicals don’t get into your food. "Clean it safely, avoid using abrasive scrubbing tools, use wood or silicone utensils and use liners," he said. "And if you're really worried about the non-stick coating, you can use a ceramic or stainless steel air fryer.” People in the comments thanked him for the explanation. " Some people will trust anyone EXCEPT actual Doctors,” one user teased. Dr Raj went on to ask his followers what their favourite meal to cook in an air fryer was, adding, "Air fried chips just taste special". Image credit: TikTok

How to clean these bathroom items that get overlooked

Cleaning the bathroom will not only make your house feel nicer for but it is important for your hygiene as so many bathroom items are used on a daily basis. Even if your bathtub, shower, tiles and sink is clean, these bathroom items deserve your frequent attention. 1. Toothbrush and toothbrush holder For obvious reasons keeping your toothbrush and toothbrush holder clean is vital to your mouth health. To keep your toothbrush clean, make sure you rinse it well after each use to avoid a build-up of toothpaste. Frequently you should do a deep clean of your toothbrush and this can be done by leaving it in a cup of vinegar for 30 minutes. The vinegar will remove the build of bacteria on your toothbrush. Remember to replace your toothbrush every 3-4 months and then you can use your old one for cleaning. A toothbrush holder can be cleaned thoroughly by putting it in the dishwasher or you can rinse it out in hot water and dish soap to remove the build-up of gunk. 2. Loofah Loofahs do a great of cleaning bodies but it is important to remember to clean them as well. Your loofah can be cleaned by submerging in a 50/50 mixture of hot water and vinegar for an hour. Then leave it to dry. This method can also be used on sponges or wash cloths. 3. Razors It is important to clean your razor as a wet razor can become rusty and a moist blade can cause ingrown hairs and irritation when shaving. To keep your razor in top condition, put some rubbing alcohol on a cotton pad and swipe across your razor. Dry your razor with a towel once you are done and store your razor in a dry place in your bathroom. 4. Toilet brush To give your toilet brush a thorough clean, rest the brush between the toilet bowl and seat after cleaning the toilet. Spray the brush with a disinfectant and then let it sit as it drips for ten minutes or so. Then rinse the brush in very hot water and allow it to drip dry again. The brush holder should also be cleaned with disinfectant and then leaving it for ten minutes and rinsing with hot water. 5. Plunger After each use of the plunger, spray it with a disinfectant and leave for ten minutes and then let it air dry. It is helpful to store your plunger with a plastic bag so that way, after you use it you can put in the bag and then take it somewhere to clean to avoid any dripping. Don’t re-use the plastic bag.
