Boeing Starliner astronauts: what six months stuck in space may do to their perception of time

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/ruth-ogden-1182467">Ruth Ogden</a>, <a href="https://theconversation.com/institutions/liverpool-john-moores-university-1319">Liverpool John Moores University</a> and <a href="https://theconversation.com/profiles/daniel-eduardo-vigo-1631723">Daniel Eduardo Vigo</a>, <a href="https://theconversation.com/institutions/pontificia-universidad-catolica-de-argentina-5531">Pontificia Universidad Católica de Argentina</a> Two astronauts marooned in space may sound like the plot of a Hollywood blockbuster, but for two <a href="https://www.nasa.gov/">Nasa</a> crew members, it is now a reality. Commander Barry Wilmore and pilot Sunita Williams are currently in limbo on the International Space Station (ISS). They arrived in the Boeing Starliner spacecraft – the first test of the spaceship with astronauts. Wilmore and Williams were supposed to stay on the ISS for around eight days and return on the same spacecraft. But there is now debate about the safety of Starliner after it experienced <a href="https://www.bbc.co.uk/news/articles/c6pp29gdwe6o">helium leaks and thruster problems</a> on its way to the ISS. In coming days, Nasa and Boeing may decide to clear Starliner to carry the astronauts back to Earth. This means their stay might not last too much longer. But if officials decide against Starliner, the astronauts face waiting an <a href="https://www.nasa.gov/news-release/update-nasa-boeing-to-stream-flight-test-mission-briefing-on-nasa/">additional six months in orbit</a> before returning. So how do astronauts cope with a potential six-month wait for a lift home? <a href="https://www.sciencedirect.com/science/article/abs/pii/0022249685900203">Waiting for things is difficult</a> at the best of times. Under normal circumstances, it is <a href="https://journals.sagepub.com/doi/full/10.1177/2043808718778982">frustrating, stressful and anxiety-provoking</a>. But in extreme situations, with high stakes, <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/j.1365-2648.2011.05638.x?casa_token=jC_hT4wqbuIAAAAA%3AGTrJPmd496aDTdirdwYi7CvLK8Q1g_oR-Em2E3EpDP0AwRCs2ko13Jpqui15BlkPiAx7MMRqA0MC">waiting can be purgatory</a>. Part of the reason that waiting is difficult is that it distorts our sense of time. Think of last time you were waiting for a delayed train, test results or a text from a potential new partner. Did it fly by or drag? For most people, time spent waiting crawls at a glacial pace. As a result, delays and periods of anticipation often feel much longer than they actually are. Waiting slows our perception of time, because it changes the amount of time that we spend <a href="https://www.jstor.org/stable/23324610?casa_token=KmtJWWmtHwQAAAAA%3AN_CUdtNakK46j4ItZaH_f__QcIGOjMnasX1NeMTRFH5YPpcmYx1JpigTfTb1bPYi5Fcus-IhtzDX0Jsz3xpqZRMDUxg0RWYhSr87V-zXz_pqS0zM&seq=2">thinking about time</a>. During normal daily life we often ignore time; our brains have a limited capacity. If time isn’t important, we simply don’t think about it, and this helps it to pass quickly. When we are waiting, our desire to know when the wait is over increases how much we think about time. This “clock watching” can make the minutes and hours feel like they are <a href="https://doi.org/10.1016/0278-2626(90)90026-K">passing at a snail’s pace</a>. Stress, discomfort and pain exacerbate this effect, meaning that waiting in difficult situations <a href="https://doi.org/10.1002/ejp.2211">can seem even longer</a>. Waiting also slows our perception of time because it what we do and how we feel. Normal life is busy and full of ever-changing activities and interactions. The sudden need to wait halts the flow of life, often leaving us with nothing else to do, thus increasing levels of boredom and frustration. In general, time filled with activity <a href="https://doi.org/10.1016/0278-2626(90)90026-K">passes more quickly</a>. We all got a taste of this during <a href="https://doi.org/10.1371/journal.pone.0235871">COVID lockdowns</a>. When we were stuck inside unable to see friends and engage in normal daily activities, the loss of routine and distractions caused time to drag for many. For the astronauts stuck on the ISS, anxiety about when they will return, limited opportunities for activities and fewer opportunities to contact friends and families combine to make their wait to return home feel significantly longer than six months – if it should come to that. However, as academics who research the effects of time on human psychology and biology, our ongoing work with crew members at research stations in Antarctica aims to shed light on whether waiting in extreme environments is different to waiting during normal daily life. <h2>A year in Antarctica</h2> While being stuck for six months on the ISS may sound like many people’s worst nightmare, it is not uncommon for scientists to spend long periods isolated and confined in extreme environments. Every year, organisations such as the Instituto Antártico Argentino (which uses the Belgrano II Antarctic station), the French Polar Institute and the Italian Antarctic Programme, in cooperation with the European Space Agency (which all use Antarctica’s Concordia station), send crews of people for up to 16 months to conduct research on the frozen continent. During the March to October <a href="https://www.bas.ac.uk/">polar winter</a>, teams spend six months in near darkness – and from May to August, in complete darkness – facing outside temperatures of up to -60C, wind speeds of 160 km/h (100 mph) and storms which prevent almost all outdoor activity. Limited internet coverage can also prevent constant communication with the outside world. For the last year, we have researched how life in Antarctica influences people’s experience of time. Each month, we asked crew members how time felt like it was passing in comparison to before their mission. Trapped on base, with limited contact with the outside world, you might expect time to drag. However, our results suggest the opposite may be true. Analysis of crew members’ experiences indicated that being constantly busy with complex tasks such as scientific research helped time to pass swiftly, according to 80% of crew responses. Only 3% of responses indicated that time actually dragged, and these reports occurred when nights were long and there was little to do. These experiences may provide hope for those stuck on the ISS. Like life on an Antarctic station, these Nasa astronauts have a busy and mentally demanding existence. These factors may help time to pass quickly. However, a key factor of their wait may be their ability to <a href="https://journals.sagepub.com/doi/10.1177/2043808718778982">tolerate the uncertainty</a> of when they will return. Wilmore and Williams will spend their time in a space equivalent to the <a href="https://www.nasa.gov/international-space-station/space-station-facts-and-figures/">inside a Boeing 747</a> plane. But better information about “when” things will happen and “why” delays are being incurred can help people to tolerate waiting and reduce its impact on their wellbeing.<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/236546/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/ruth-ogden-1182467">Ruth Ogden</a>, Professor of the Psychology of Time, <a href="https://theconversation.com/institutions/liverpool-john-moores-university-1319">Liverpool John Moores University</a> and <a href="https://theconversation.com/profiles/daniel-eduardo-vigo-1631723">Daniel Eduardo Vigo</a>, Senior Researcher in Chronobiology, <a href="https://theconversation.com/institutions/pontificia-universidad-catolica-de-argentina-5531">Pontificia Universidad Católica de Argentina</a> Image credits: NASA This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

NASA astronauts stranded in space

Two astronauts are stranded in space after a simple week-long trip to the International Space Station (ISS) has turned into a possible eight-month trip. NASA astronauts Butch Wilmore and Suni Williams encountered technical issues with Boeing’s Starliner spacecraft days after departing for their eight-day trip in June and now may be stuck indefinitely. The trip Mr Wilmore, 61, and Ms Williams, 58, were on was designed to see how the new spacecraft performs before it is used more regularly. However, problems emerged as it made its approach to the ISS, including leaks in its propulsion system and some of its thrusters shutting down. While they made it to the space station safely, they will need an alternative mode of transport to get home if the Starliner is not deemed safe to return to Earth. One potential option being considered to get the astronauts safely home is to attach the two astronauts to a separate mission that is scheduled to launch in September, and return them to earth with that mission in February 2025. That flight to the space station will be made by a SpaceX Crew Dragon craft, and while the initial plan was for four crew members to be aboard, two of the seats could be left empty if needed. That plan would mean the astronauts would spend more than eight months, rather than eight days, aboard the International Space Station. NASA officials said it could take a week or more for a final decision to be made about how to get the stranded astronauts safely home. Thankfully, NASA has used a SpaceX rocket to deliver more food and supplies to the ISS, including extra clothes for the two astronauts, as the pair remain in high spirits. Image credits: NASA

How sustainable is your weekly grocery shop? These small changes can have big benefits

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/michalis-hadjikakou-129930">Michalis Hadjikakou</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/carla-archibald-283811">Carla Archibald</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/ozge-geyik-1402545">Özge Geyik</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>, and <a href="https://theconversation.com/profiles/pankti-shah-1547393">Pankti Shah</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> You might think eating more sustainably requires drastic changes, such as shifting to a <a href="https://theconversation.com/vegan-diet-has-just-30-of-the-environmental-impact-of-a-high-meat-diet-major-study-finds-210152">vegan diet</a>. While a plant-based diet is <a href="https://www.nature.com/articles/s43016-023-00795-w">undeniably</a> good for the Earth, our <a href="https://www.sciencedirect.com/science/article/pii/S2352550924001945#f0025">new research</a> shows modest changes to your eating habits can also have significant environmental benefits. We assessed how food products on Australian supermarket shelves stack up against key environmental indicators, such as carbon emissions and water use. We found swapping the most environmentally harmful foods for more sustainable options within the same food group, such as switching from beef burgers to chicken burgers, can significantly reduce carbon emissions – by up to 96% in some instances. The last thing we want to do is take the pleasure away from eating. Instead, we want to help consumers make realistic dietary changes that also help ensure a sustainable future. So read on to find out which simple food swaps can best achieve this. <h2>Informing sustainable diets</h2> The environmental impact of foods can be estimated using an approach known as a <a href="https://www.cell.com/one-earth/fulltext/S2590-3322(19)30128-9#:%7E:text=In%20this%20Primer%2C%20we%20introduce,cycle%20of%20a%20product%20system.">life-cycle assessment</a>. This involves identifying the “inputs” required along the food supply chain, such as fertiliser, energy, water and land, and tracking them from farm to fork. From this we can calculate a product’s “footprint” – or environmental impact per kilogram of product – and compare it to other foods. Most studies of environmental footprints focus on the raw ingredients that make up food products (such as beef, wheat or rice) rather than the packaged products people see on shelves (such as beef sausages, pasta or rice crackers). Of the studies that do focus on packaged foods, most only consider a fraction of the products available to consumers. What’s more, a lot of research considers only the carbon emissions of food products, excluding other important measures such as water use. And some studies use global average environmental footprints, which <a href="https://www.science.org/doi/10.1126/science.aaq0216">vary significantly</a> between countries. Our research set out to overcome these limitations. We aligned environmental footprints with the products people find on supermarket shelves, and covered a huge range of food and beverage products available in Australia. We also included many environmental indicators, to allow a <a href="https://www.pnas.org/doi/full/10.1073/pnas.2120584119">more complete picture</a> of the sustainability of different foods. <h2>What we did</h2> Key to our research was the <a href="https://www.georgeinstitute.org.au/projects/foodswitch">FoodSwitch database</a>, which compiles food labelling and ingredient data from images of packaged food and beverages. It covers more than 90% of the Australian packaged food market. We combined the database with a <a href="https://www.sciencedirect.com/science/article/pii/S0959652623029748">mathematical method</a> that sums the environmental impact of ingredients, to quantify the footprint of the product as a whole. From this, we estimated the environmental footprint of 63,926 food products available in Australian supermarkets. We then simulated the potential benefits of making “realistic” switches between products – that is, switches within the same food category. <h2>Our findings</h2> The results show how making a small dietary change can have big environmental consequences. For a shopping basket composed of items from eight food groups, we simulate the benefits of swapping from high-impact towards medium- or low-impact food products. Our analysis assumes a starting point from the most environmentally harmful products in each food group – for example, sweet biscuits, cheese and beef burger patties. A shift to the medium-impact foods for all eight items – such as a muffin, yoghurt and sliced meat – can lead to at least a 62% reduction in environmental impact. Shifts towards the most sustainable choice for all items – bread, soy milk or raw poultry – can achieve a minimum 77% reduction. This analysis ends at the supermarket shelves and does not include additional food processing by the consumer. For example, raw meat will usually be cooked before human consumption, which will expand its environmental footprint to varying degrees, <a href="https://www.nature.com/articles/s43016-020-00200-w">depending on the method used</a>. See the below info-graphic for more detail. The full results are available in <a href="https://www.sciencedirect.com/science/article/pii/S2352550924001945">our study</a>. <hr /> <iframe id="sR5yB" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/sR5yB/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> <h2>What next?</h2> Many people are looking for ways to live more sustainably. Insufficient or complex information can fuel confusion and anxiety in consumers, <a href="https://theconversation.com/reducing-eco-anxiety-is-a-critical-step-in-achieving-any-climate-action-210327">leading to inaction or paralysis</a>. Consumers need more information and support to choose more sustainable foods. Supermarkets and retailers also have an important role to play – for example, by giving sustainable products <a href="https://journals.sagepub.com/doi/10.1177/07439156211008898">prominent shelf placement</a>. Attractive pricing is also crucial – particularly in the midst of a <a href="https://theconversation.com/au/topics/cost-of-living-crisis-115238">cost-of-living crisis</a> when it can be difficult to prioritise sustainability over cost. Government interventions, such as information campaigns and <a href="https://journals.sagepub.com/doi/10.1177/07439156211008898">taxing high-impact products</a>, can also help. Food labelling is also important. The European Union <a href="https://environment.ec.europa.eu/topics/circular-economy/eu-ecolabel/product-groups-and-criteria_en">is leading the way</a> with measures such as the <a href="https://docs.score-environnemental.com/v/en">eco-score</a>, which integrates 14 environmental indicators into a single score from A to E. Apps such as <a href="https://www.georgeinstitute.org/projects/ecoswitch">ecoSwitch</a> can also <a href="https://www.sciencedirect.com/science/article/pii/S1326020024000268?via%3Dihub">empower consumers</a>. The diets of people in developed nations such as Australia <a href="https://theconversation.com/sustainable-shopping-want-to-eat-healthy-try-an-eco-friendly-diet-89086">exert a high toll on our planet</a>. More sustainable food choices are vital to achieving a <a href="https://www.thelancet.com/commissions/EAT">sustainable future for humanity</a>. We hope our research helps kick-start positive change.<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/234367/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/michalis-hadjikakou-129930">Michalis Hadjikakou</a>, Senior Lecturer in Environmental Sustainability, School of Life and Environmental Sciences, Faculty of Science, Engineering & Built Environment, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/carla-archibald-283811">Carla Archibald</a>, Research Fellow, Conservation Science, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/ozge-geyik-1402545">Özge Geyik</a>, Visitor, School of Life and Environmental Sciences, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>, and <a href="https://theconversation.com/profiles/pankti-shah-1547393">Pankti Shah</a>, PhD student, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Leap of imagination: how February 29 reminds us of our mysterious relationship with time and space

<a href="https://theconversation.com/profiles/emily-ohara-874665">Emily O'Hara</a>, <a href="https://theconversation.com/institutions/auckland-university-of-technology-1137">Auckland University of Technology</a> If you find it intriguing that February 28 will be followed this week by February 29, rather than March 1 as it usually is, spare a thought for those alive in 1582. Back then, Thursday October 4 was followed by Friday October 15. Ten whole days were snatched from the present when Pope Gregory XIII issued a papal bull to “restore” the calendar from discrepancies that had crept into the Julian calendar, introduced by Julius Caesar in 45 BCE. The new Gregorian calendar returned the northern hemisphere’s vernal equinox to its “proper” place, around March 21. (The equinox is when the Earth’s axis is tilted neither toward nor away from the sun, and is used to determine the date of Easter.) The Julian calendar had observed a leap year every four years, but this meant time had drifted out of alignment with the dates of celestial events and astronomical seasons. In the Gregorian calendar, leap days were added only to years that were a multiple of four – like 2024 – with an exception for years that were evenly divisible by 100, but not 400 – like 1700. Simply put, leap days exist because it doesn’t take a neat 365 days for Earth to orbit the Sun. It takes 365.2422 days. Tracking the movement of celestial objects through space in an orderly pattern doesn’t quite work, which is why we have February – time’s great mop. <h2>Time and space</h2> This is just part of the history of how February – the shortest month, and originally the last month in the Roman calendar – came to have the job of absorbing those inconsistencies in the temporal calculations of the world’s most commonly used calendar. There is plenty of <a href="https://theconversation.com/leap-day-fixing-the-faults-in-our-stars-54032">science</a>, <a href="https://theconversation.com/explainer-the-science-behind-leap-years-and-how-they-work-54788">maths</a> and <a href="https://theconversation.com/how-a-seasonal-snarl-up-in-the-mid-1500s-gave-us-our-strange-rules-for-leap-years-132659">astrophysics</a> explaining the relationship between time and the planet we live on. But I like to think leap years and days offer something even more interesting to consider: why do we have calendars anyway? And what have they got to do with how we understand the wonder and strangeness of our existence in the universe? Because calendars tell a story, not just about time, but also about space. Our reckoning of time on Earth is through our spatial relationship to the Sun, Moon and stars. Time, and its place in our lives, sits somewhere between the scientific, the celestial and the spiritual. It is <a href="https://shop.whitechapelgallery.org/products/time">notoriously slippery, subjective and experiential</a>. It is also marked, tracked and determined in myriad ways across different cultures, from tropical to solar to <a href="https://www.stuff.co.nz/pou-tiaki/300062097/matariki-and-the-maramataka-the-mori-lunar-calendar">lunar</a> calendars. It is the Sun that measures a day and gives us our first reference point for understanding time. But it is the <a href="https://librarysearch.aut.ac.nz/vufind/Record/1145999?sid=25214690">Moon</a>, as a major celestial body, that extends our perception of time. By stretching a span of one day into something longer, it offers us a chance for philosophical reflection. The Sun (or its effect at least) is either present or not present. The Moon, however, goes through phases of transformation. It appears and disappears, changing shape and hinting that one night is not exactly like the one before or after. The Moon also has a distinct rhythm that can be tracked and understood as a pattern, giving us another sense of duration. Time is just that – overlapping durations: instants, seconds, minutes, hours, days, weeks, months, years, decades, lifetimes, centuries, ages. <h2>The elusive Moon</h2> It is almost impossible to imagine how time might feel in the absence of all the tools and gadgets we use to track, control and corral it. But it’s also hard to know what we might do in the absence of time as a unit of productivity – a measurable, dispensable resource. The closest we might come is simply to imagine what life might feel like in the absence of the Moon. Each day would rise and fall, in a rhythm of its own, but without visible reference to anything else. Just endless shifts from light to dark. Nights would be almost completely dark without the light of the Moon. Only stars at a much further distance would puncture the inky sky. The world around us would change – trees would grow, mammals would age and die, land masses would shift and change – but all would happen in an endless cycle of sunrise to sunset. The light from the Sun takes <a href="https://www.skyatnightmagazine.com/space-science/how-take-light-from-sun-reach-earth">eight minutes</a> to reach Earth, so the sunlight we see is always eight minutes in the past. I remember sitting outside when I first learned this, and wondering what the temporal delay might be between me and other objects: a plum tree, trees at the end of the street, hills in the distance, light on the horizon when looking out over the ocean, stars in the night sky. Moonlight, for reference, takes about <a href="https://www.pbs.org/seeinginthedark/astronomy-topics/light-as-a-cosmic-time-machine.html">1.3 seconds</a> to get to Earth. Light always travels at the same speed, it is entirely constant. The differing duration between how long it takes for sunlight or moonlight to reach the Earth is determined by the space in between. Time on the other hand, is anything but constant. There are countless ways we characterise it. The mere fact we have so many calendars and ways of describing perceptual time hints at our inability to pin it down. Calendars give us the impression we can, and have, made time predictable and understandable. Leap years, days and seconds serve as a periodic reminder that we haven’t.<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/224503/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/emily-ohara-874665">Emily O'Hara</a>, Senior Lecturer, Spatial Design + Temporary Practices, <a href="https://theconversation.com/institutions/auckland-university-of-technology-1137">Auckland University of Technology</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

“Bloody ripper of a meteor” lights up Perth skies

A few lucky Western Australians have witnessed the moment a bright green meteor flashed brightly across the state's South West. The meteor was the size of a cricket ball and had a 200-kilometre-long tail, which was first spotted at around 8.50pm on Wednesday after entering the atmosphere over Pemberton. The rare spectacle, which only happens around three times a year, lasted about five seconds and travelled at a speed of 30 km/h before the mix of iron, rock and ice dissolved over the Southern Ocean. “Iron meteors give off that beautiful green glow,” Perth Observatory spokesperson Matt Woods told 7NEWS. Experts also said that this was triggered by the outer layer of the meteor melting because of intense friction. The observatory said that the meteor had set off a flood of messages, emails and calls from the people that witnessed the natural phenomenon. “That was a bloody ripper of a meteor tonight,” they posted on their Facebook page. One witness said that you had to see it with your own eyes to fully appreciate its beauty. “I will say it was way better in person. It looked almost rainbow-coloured. Just spectacular,” commented one person. “Did anyone just see a bright streak of light shooting from the sky? It was too bright to be a shooting star,” another person shared on social media. “It was massive and extremely bright.” Image: 7NEWS

"It was beautiful": Rare rainbow cloud stuns small farming town

The locals of a small farming town in Western Australia have been delighted with the sighting of a rare rainbow cloud. The colourful weather phenomenon appeared above the town of Goomalling, about 130km northwest of Perth in Western Australia, on Tuesday morning. Jenni Shaw was at her family-owned business when she got a text from a friend instructing her to look up at the sky. "We all went out the front and had a look and there was some bright, rainbow-type clouds in the sky that we hadn't seen before," she told <a href="https://www.abc.net.au/news/2023-10-24/rainbow-cloud-iridescence-irisation-delights-wheatbelt-community/103016928" target="_blank" rel="noopener">ABC</a>. “It was beautiful,” she said. “But we were a bit like ‘why is that like that?

"It's quite a rare phenomenon to catch in person," she said. "It's the perfect storm of conditions: the sun's at the right angle, the clouds are not too thin and not too thick that they're being blocked out, and the sunlight has just created this spectacle of coloured light." <div data-component="EmphasisedText"> "It's an absolutely stunning photo." </div> Lucky local residents said it wasn’t the first time they’d seen the special clouds in the area. “I have seen clouds like this a few times in my travels, mostly in the Wheatbelt,” Jill Lefroy wrote on Facebook. “Pretty awesome seeing a rainbow with no rain!” Image credits: Facebook

Is it okay to kiss your pet? The risk of animal-borne diseases is small, but real

<a href="https://theconversation.com/profiles/sarah-mclean-1351935">Sarah McLean</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> and <a href="https://theconversation.com/profiles/enzo-palombo-249510">Enzo Palombo</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> Our relationship with pets has changed drastically in recent decades. Pet ownership is at an all-time high, with <a href="https://animalmedicinesaustralia.org.au/media-release/more-than-two-thirds-of-australian-households-now-own-a-pet/">a recent survey</a> finding 69% of Australian households have at least one pet. We spend an estimated A$33 billion every year on caring for our fur babies. While owning a pet is linked to numerous <a href="https://www.onehealth.org/blog/10-mental-physical-health-benefits-of-having-pets">mental and physical health benefits</a>, our pets can also harbour infectious diseases that can sometimes be passed on to us. For most people, the risk is low. But some, such as pregnant people and those with weakened immune systems, are at <a href="https://www.cdc.gov/healthypets/specific-groups/high-risk/index.html">greater risk</a> of getting sick from animals. So, it’s important to know the risks and take necessary precautions to prevent infections. <h2>What diseases can pets carry?</h2> Infectious diseases that move from animals to humans are called zoonotic diseases or <a href="https://www.cdc.gov/onehealth/basics/zoonotic-diseases.html">zoonoses</a>. More than <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3668296/#B18">70 pathogens</a> of companion animals are known to be transmissible to people. Sometimes, a pet that has a zoonotic pathogen may look sick. But often there may be no visible symptoms, making it easier for you to catch it, because you don’t suspect your pet of harbouring germs. Zoonoses can be transmitted directly from pets to humans, such as through contact with saliva, bodily fluids and faeces, or indirectly, such as through contact with contaminated bedding, soil, food or water. Studies suggest <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4500695/">the prevalence of pet-associated zoonoses is low</a>. However, the true number of infections is likely <a href="https://www.mdpi.com/1660-4601/17/11/3789">underestimated</a> since many zoonoses are not “<a href="https://www.healthdirect.gov.au/notification-of-illness-and-disease">notifiable</a>”, or may have multiple exposure pathways or generic symptoms. Dogs and cats are major reservoirs of zoonotic infections (meaning the pathogens naturally live in their population) caused by viruses, bacteria, fungi and parasites. <a href="https://www.who.int/data/gho/data/themes/topics/rabies">In endemic regions in Africa and Asia</a>, dogs are the main source of rabies which is transmitted through saliva. Dogs also commonly carry Capnocytophaga bacteria <a href="https://www.cdc.gov/capnocytophaga/index.html">in their mouths and saliva</a>, which can be transmitted to people through close contact or bites. The vast majority of people won’t get sick, but these bacteria can occasionally cause infections in people with weakened immune systems, <a href="https://www.cdc.gov/capnocytophaga/signs-symptoms/index.html">resulting</a> in severe illness and sometimes death. Just last week, such a death <a href="https://thewest.com.au/news/wa/tracy-ridout-perth-mum-dies-11-days-after-rare-bacterial-infection-from-minor-dog-bite-c-11748887">was reported in Western Australia</a>. Cat-associated zoonoses include a number of illnesses spread by the faecal-oral route, such as giardiasis, campylobacteriosis, salmonellosis and toxoplasmosis. This means it’s especially important to wash your hands or use gloves whenever handling your cat’s litter tray. Cats can also sometimes transmit infections through bites and scratches, including the aptly named <a href="https://www.cdc.gov/healthypets/diseases/cat-scratch.html#:%7E:text=Cat%20scratch%20disease%20(CSD)%20is,the%20surface%20of%20the%20skin.">cat scratch disease</a>, which is caused by the bacterium Bartonella henselae. Both dogs and cats are also reservoirs for <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10122942/">methicillin-resistant bacterium Staphylococcus aureus</a> (MRSA), with close contact with pets identified as an important risk factor for zoonotic transmission. <h2>Birds, turtles and fish can also transmit disease</h2> But it’s not just dogs and cats that can spread diseases to humans. Pet birds can occasionally transmit <a href="https://www.cdc.gov/pneumonia/atypical/psittacosis/">psittacosis</a>, a bacterial infection which causes pneumonia. Contact with <a href="https://www.fda.gov/animal-veterinary/animal-health-literacy/pet-turtles-source-germs">pet turtles</a> has been linked to Salmonella infections in humans, particularly in young children. Even pet fish have been linked to a <a href="https://www.cdc.gov/healthypets/pets/fish.html">range of bacterial infections</a> in humans, including vibriosis, mycobacteriosis and salmonellosis. Close contact with animals – and some behaviours in particular – increase the risk of zoonotic transmission. <a href="https://pubmed.ncbi.nlm.nih.gov/19398275/">A study from the Netherlands</a> found half of owners allowed pets to lick their faces, and 18% allowed dogs to share their bed. (Sharing a bed increases the duration of exposure to pathogens carried by pets.) The same study found 45% of cat owners allowed their cat to jump onto the kitchen sink. Kissing pets has also been linked to occasional zoonotic infections in pet owners. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3298380/">In one case</a>, a woman in Japan developed meningitis due to Pasteurella multicoda infection, after regularly kissing her dog’s face. These bacteria are often found in the oral cavities of dogs and cats. Young children are also more likely to engage in behaviours which increase their risk of <a href="https://www.cdc.gov/healthypets/specific-groups/high-risk/children.html?CDC_AA_refVal=https%3A%2F%2Fwww.cdc.gov%2Fhealthypets%2Fspecific-groups%2Fchildren.html">getting sick</a> from animal-borne diseases – such as putting their hands in their mouth after touching pets. Children are also less likely to wash their hands properly after handling pets. Although anybody who comes into contact with a zoonotic pathogen via their pet can become sick, certain people are more likely to suffer from serious illness. These people include the young, old, pregnant and immunosuppressed. For example, while most people infected with the toxoplasmosis parasite will experience only mild illness, it can be life-threatening or <a href="https://www.nhs.uk/common-health-questions/pregnancy/what-are-the-risks-of-toxoplasmosis-during-pregnancy/">cause birth defects in foetuses</a>. <h2>What should I do if I’m worried about catching a disease from my pet?</h2> There are a number of good hygiene and pet husbandry practices that can reduce your risk of becoming sick. These include: <ul> <li>washing your hands after playing with your pet and after handling their bedding, toys, or cleaning up faeces</li> <li>not allowing your pets to lick your face or open wounds</li> <li>supervising young children when they are playing with pets and when washing their hands after playing with pets</li> <li>wearing gloves when changing litter trays or cleaning aquariums</li> <li>wetting bird cage surfaces when cleaning to minimise aerosols</li> <li>keeping pets out of the kitchen (especially cats who can jump onto food preparation surfaces)</li> <li>keeping up to date with preventative veterinary care, including vaccinations and worm and tick treatments</li> <li>seeking veterinary care if you think your pet is unwell.</li> </ul> It is especially important for those who are at a higher risk of illness to take precautions to reduce their exposure to zoonotic pathogens. And if you’re thinking about getting a pet, ask your vet which type of animal would best suit your personal circumstances.<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/210898/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/sarah-mclean-1351935">Sarah McLean</a>, Lecturer in environmental health, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> and <a href="https://theconversation.com/profiles/enzo-palombo-249510">Enzo Palombo</a>, Professor of Microbiology, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Almost half of Moon missions fail. Why is space still so hard?

<a href="https://theconversation.com/profiles/gail-iles-761554">Gail Iles</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> In 2019, India attempted to land a spacecraft on the Moon – and ended up painting a kilometres-long streak of debris on its barren surface. Now the Indian Space Research Organisation has returned in triumph, with the Chandrayaan-3 lander <a href="https://www.reuters.com/world/india/india-counts-down-crucial-moon-landing-2023-08-23/">successfully touching down</a> near the south pole of Earth’s rocky neighbour. India’s success came just days after a <a href="https://www.nature.com/articles/d41586-023-02659-6">spectacular Russian failure</a>, when the Luna 25 mission tried to land nearby and “ceased to exist as a result of a collision with the lunar surface”. These twin missions remind us that, close to 60 years after the first successful “soft landing” on the Moon, spaceflight is still difficult and dangerous. Moon missions in particular are still a coin flip, and we have seen several high-profile failures in recent years. Why were these missions unsuccessful and why did they fail? Is there a secret to the success of countries and agencies who have achieved a space mission triumph? <h2>An exclusive club</h2> The Moon is the only celestial location humans have visited (so far). It makes sense to go there first: it’s the closest planetary body to us, at a distance of around 400,000 kilometres. Yet only four countries have achieved successful “soft landings” – landings which the spacecraft survives – on the lunar surface. The USSR was the first. The <a href="https://en.wikipedia.org/wiki/Luna_9">Luna 9</a> mission safely touched down on the Moon almost 60 years ago, in February 1966. The United States followed suit a few months later, in June 1966, with the <a href="https://www.smithsonianmag.com/air-space-magazine/1966-the-real-first-moon-landing-118785850/">Surveyor 1</a> mission. China was the next country to join the club, with the <a href="https://en.wikipedia.org/wiki/Chang%27e_3">Chang'e 3</a> mission in 2013. And now India too has arrived, with <a href="https://amp.theguardian.com/science/2023/aug/23/india-chandrayaan-3-moon-landing-mission">Chandrayaan-3</a>. Missions from Japan, the United Arab Emirates, Israel, Russia, the European Space Agency, Luxembourg, South Korea and Italy have also had <a href="https://en.wikipedia.org/wiki/List_of_missions_to_the_Moon">some measure of lunar success</a> with fly-bys, orbiters and impacts (whether intentional or not). <h2>Crashes are not uncommon</h2> On August 19 2023, the Russian space agency Roscosmos announced that “communication with the <a href="https://www.nature.com/articles/d41586-023-02659-6">Luna 25 spacecraft</a> was interrupted”, after an impulse command was sent to the spacecraft to lower its orbit around the Moon. Attempts to contact the spacecraft on August 20 were unsuccessful, leading Roscosmos to determine Luna 25 had crashed. Despite more than 60 years of spaceflight experience extending from the USSR to modern Russia, this mission failed. We don’t know exactly what happened – but the current situation in Russia, where resources are stretched thin and tensions are high due to the ongoing war in Ukraine, may well have been a factor. The Luna 25 failure recalled two high-profile lunar crashes in 2019. In April that year, the Israeli <a href="https://en.wikipedia.org/wiki/Beresheet">Beresheet lander</a> crash-landed after a gyroscope failed during the braking procedure, and the ground control crew was unable to reset the component due to a loss of communications. It was later reported a capsule containing microscopic creatures called tardigrades, in a dormant “cryptobiotic” state, may have survived the crash. And in September, India sent its own Vikram lander down to the surface of the Moon – but it did not survive the landing. NASA later <a href="https://www.theguardian.com/science/2019/dec/03/indias-crashed-vikram-moon-lander-spotted-on-lunar-surface">released an image</a> taken by its Lunar Reconnaissance Orbiter showing the site of the Vikram lander’s impact. Debris was scattered over almost two dozen locations spanning several kilometres. <h2>Space is still risky</h2> Space missions are a risky business. Just over <a href="https://www.businessinsider.in/science/space/news/success-rate-of-lunar-missions-is-a-little-over-50-as-per-nasa-database/articleshow/101774227.cms">50% of lunar missions succeed</a>. Even <a href="https://ntrs.nasa.gov/api/citations/20190002705/downloads/20190002705.pdf">small satellite missions</a> to Earth’s orbit don’t have a perfect track record, with a success rate somewhere between 40% and 70%. We could compare uncrewed with crewed missions: around <a href="https://www.bbc.com/future/article/20230518-what-are-the-odds-of-a-successful-space-launch">98% of the latter are successful</a>, because people are more invested in people. Ground staff working to support a crewed mission will be more focused, management will invest more resources, and delays will be accepted to prioritise the safety of the crew. We could talk about the details of why so many uncrewed missions fail. We could talk about technological difficulties, lack of experience, and even the political landscapes of individual countries. But perhaps it’s better to step back from the details of individual missions and look at averages, to see the overall picture more clearly. <h2>The big picture</h2> Rocket launches and space launches are not very common in the scheme of things. There are <a href="https://www.pd.com.au/blogs/how-many-cars-in-the-world/">around 1.5 billion cars</a> in the world, and perhaps <a href="https://www.travelweek.ca/news/exactly-many-planes-world-today/">40,000 aeroplanes</a>. By contrast, there have been fewer than <a href="https://planet4589.org/space/gcat/data/derived/launchlog.html">20,000 space launches</a> in all of history. Plenty of things still go wrong with cars, and problems occur even in the better-regulated world of planes, from loose rivets to computers overriding pilot inputs. And we have more than a century of experience with these vehicles, in every country on the planet. So perhaps it’s unrealistic to expect spaceflight – whether it’s the launch stage of rockets, or the even rarer stage of trying to land on an alien world – to have ironed out all its problems. We are still very much in the early, pioneering days of space exploration. <h2>Monumental challenges remain</h2> If humanity is ever to create a fully fledged space-faring civilisation, we must <a href="https://www.wired.com/2016/02/space-is-cold-vast-and-deadly-humans-will-explore-it-anyway/">overcome monumental challenges</a>. To make long-duration, long-distance space travel possible, there are a huge number of problems to be solved. Some of them seem within the realm of the possible, such as better radiation shielding, self-sustaining ecosystems, autonomous robots, extracting air and water from raw resources, and zero-gravity manufacturing. Others are still speculative hopes, such as faster-than-light travel, instantaneous communication, and artificial gravity. Progress will be little by little, small step by slightly larger step. Engineers and space enthusiasts will keep putting their brainpower, time and energy into space missions, and they will gradually become more reliable. And maybe one day we’ll see a time when going for a ride in your spacecraft is as safe as getting in your car. <hr /> Correction: a typing error in the original version of this article put the Surveyor 1 mission in 1996, rather than its actual year of 1966.<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/211914/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/gail-iles-761554">Gail Iles</a>, Senior Lecturer in Physics, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

International Travel

Try these tricks the next time small talk becomes unbearable

Real talk Bonnie Todd runs 250 food tours a year – a job that puts her in contact with hundreds of new people every week. Food-lovers come to her for an introduction to local tastes and flavours. And a large part of what keeps her guests satisfied, and willing to recommend her business to others, is the personal connection she makes with them. “I try to get past the small talk and general recommendations pretty quickly,” says the 42-year-old. “It’s all about finding common ground within the group, and trying to make it a unique experience. So I’m always asking questions. And when I find that spark of commonality, I dig into it.” The practice is key to Todd’s approach because, unlike many tours, hers require people to sit together sharing food and drinks. When groups don’t gel, or never get past the “Where are you from?” stage, what should be a stimulating experience can turn into an awkward and draining couple of hours. We’ve all been there: trapped in a superficial exchange that bounces aimlessly from one meaningless topic to the next. It can make you never want to step foot into another party again. But don’t despair: there are some tactics that can help you turn boring small talk into an energising conversation. Put yourself out there Improv performer Natalie Metcalfe’s job is to keep a scene going – to create an exchange that’s compelling for both the people involved and for a live audience. “In improv, it’s all about offers,” she says, referring to the act of bringing new information into the dialogue. Through these back-and-forths, the relationship between the characters is established and that kicks things off. “It’s the same thing in a regular conversation. You’re constantly making offers to see if you and the person you’re talking to can connect.” An offer in real life can be as simple as complimenting someone on what they’re wearing, and asking them about it. You can try sharing something you recently learned, or an interest you’ve just developed, creating an opening for the other person to ask you a question. Or, you can describe a relatable problem you’re having – a noisy neighbour, a plant that’s not thriving, a question of etiquette – as a prompt for advice, or some cooperative troubleshooting. One of Todd’s go-to approaches is to share a personal story of her own that relates to the other person’s experience. “If I find out someone has been to a place I’ve travelled, I’ll tell them an anecdote about what I did there, and ask them to share their own story.” Of course, putting yourself out there can sometimes feel scary, even when you’re not on stage. But Misha Glouberman, who runs a course called How to Talk to People About Things, says taking that leap pays off. “A lot of the time in conversations, there’s something we’re interested in, but there’s a part of us that doesn’t want to take the risk of revealing it because we think it might be boring or inappropriate.” But the result of following those internal cues of fascination has the opposite effect, he says. “People like learning about other people’s interests. So be more open about yours, and a little more curious about theirs as well.” Be inquisitive and listen Radio interviewer Terry Gross once said, that the only icebreaker you’ll ever need is, “Tell me about yourself.” Instead of asking a pointed question like “What do you do?”, this type of open question gives someone a chance to offer up a topic they might be more excited to discuss. “Talking about yourself is really pleasurable. It activates the exact same hormone in your brain as sex,” says Celeste Headlee, the author of We Need to Talk: How to Have Conversations That Matter. “Another tip you can take from neuroscience is that if you start a conversation by allowing someone to feel good about themselves, then they’ll be more open to new ideas and new thoughts for the rest of the conversation.” Of course, upping your curiosity quotient needs to be paired with actually paying attention to the answer. “Listening is hard for homo sapiens. It’s not something our species does easily,” says Headlee. Indeed, people often start crafting their response before the person they’re talking to has finished speaking. Or they’ll get distracted, thinking about an email they forgot to answer. Since a great conversation is by definition a two-way street, these habits have the effect of ending one before it can even begin. Intentional listening, on the other hand, is a key to an empathetic, engaging dialogue. Use disagreement wisely According to Headlee, one of the other things that gets in the way of a meaningful conversation is the all-too-human need to be right. “A really common mistake is the ‘well, actually’ response,” she says, referring to that deflating moment when a person lets their need to correct you about a small detail you’ve just mentioned get in the way of continuing a story. “Google has made this worse,” she adds. “You’ll say, I went to the hotel with the largest patio in the entire world, and while you’re still talking, the person is already on their phone looking to see if that’s actually true.” But while trivial arguments can be an obstacle to a good conversation, Glouberman points out that differences of opinion can also help propel a chat into richer territory. “We assume that the world is just as we see it, that we see it directly,” he says. “But of course all of psychology and neuroscience tells us that’s not the case.” A respectful disagreement, if the other party is open to it, is a great opportunity to enrich your view of the world by understanding someone else’s.

Coles praised for helping small town through cost of living crisis

Coles has been praised for the innovative way they are helping a small Aussie town to combat the ongoing cost of living crisis. The supermarket giant has started contributing to a community pantry in the coastal town of Ulladulla, 200km south of Sydney, which gives struggling locals basic grocery staples. The Little Free Food Pantry in Ulladulla was set up by local woman Coralie Smith and her mother Melissa, who were on a mission to reduce food waste, while also give back to their community as the cost of living continues to take hold. The motto "take what you need, give what you can" is plastered along the top of the pantry, set up outside the local scout hall, designed for people to help themselves to food to feed their families. Most of the food in the community cupboard has been donated by the local Coles supermarket, which provides a range of baked items, meats and fresh produce daily. Woolworths has also contributed items to the pantry every week, while also being topped up by generous locals. One local woman named Michelle has been using the service for almost three months. Before the pantry was established, Michelle was only able to afford to eat just one meal a day. "I'm working three jobs because of the high interest rates and the cost of living," she told Yahoo News Australia. "When I collected my first hamper all I could do is cry". The first time she was offered food she felt extremely "overwhelmed" but "now I'm definitely eating more, and am able to keep up with my mortgage and bills". Image credits: Facebook / Shutterstock

Mystery object washed up on WA beach finally identified

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

2001: A Space Odyssey still leaves an indelible mark on our culture 55 years on

<a href="https://theconversation.com/profiles/nathan-abrams-122305">Nathan Abrams</a>, <a href="https://theconversation.com/institutions/bangor-university-1221">Bangor University</a> 2001: A Space Odyssey is a landmark film in the history of cinema. It is a work of extraordinary imagination that has transcended film history to become something of a cultural marker. And since 1968, it has penetrated the psyche of not only other filmmakers but society in general. It is not an exaggeration to say that 2001 single-handedly reinvented the science fiction genre. The visuals, music and themes of 2001 left an inedible mark on subsequent science fiction that is still evident today. When <a href="https://www.simonandschuster.com/books/Kubrick/Robert-P-Kolker/9781639366248">Stanley Kubrick</a> began work on 2001 in the mid-1960s, he was told by studio executive Lew Wasserman: “Kid, you don’t spend over a million dollars on science fiction movies. You just don’t do that.” By that point, the golden age of science fiction film had run its course. During its heyday, there was a considerable variety of content within the overarching genre. There had been serious attempts to foretell space travel. Destination Moon, directed by Irving Pichel and produced by George Pal in 1950, and, in mid-century, Byron Haskin’s Conquest of Space both fantasised space travel and, in Haskin’s film, a space station, which Kubrick would elaborate on in 2001. <figure><iframe src="https://www.youtube.com/embed/oR_e9y-bka0?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>The trailer for 2001: A Space Odyssey.</figcaption></figure> Most 1950s science fiction films, though, were cheap B-movie fare and looked it. They involved alien invasions with an ideological and allegorical subtext. They were cultural, cinematic imaginations of the danger of communism, which in the overheated political atmosphere of the time was seen as an imminent threat to the American way of life. The aliens in most science fiction films were out simply to destroy or take over humanity; they were expressions, to use the title of a Susan Sontag essay, of “<a href="https://americanfuturesiup.files.wordpress.com/2013/01/sontag-the-imagination-of-disaster.pdf">the imagination of disaster</a>”. There were some exceptions, including Byron Haskin’s film version of The War of the Worlds and Robert Wise’s The Day the Earth Stood Still. By 1968, then, as the lights went down, very few people knew what was about to transpire and they certainly were not prepared for what did. The film opened in near darkness as the strains of Thus Spake Zarathustra by Richard Strauss were heard. The cinema was dazzled into light, as if Kubrick had <a href="https://www.rutgersuniversitypress.org/stanley-kubrick/9780813587110">remade Genesis</a>. The subsequent 160 or so minutes (the length of his original cut before he edited 19 minutes out of it) took the viewer on what was marketed as “the ultimate trip”. Kubrick had excised almost every element of explanation leaving an elusive, ambiguous and thoroughly unclear film. His decisions contributed to long silent scenes, offered without elucidation. It contributed to the film’s almost immediate critical failure but its ultimate success. It was practically a silent movie. 2001 was an experiment in film form and content. It exploded the conventional narrative form, restructuring the conventions of the three-act drama. The narrative was linear, but radically, spanning aeons and ending in a timeless realm, all without a conventional movie score. Kubrick used 19th-century and modernist music, such as Strauss, György Ligeti and Aram Khachaturian. <h2>Vietnam</h2> The movie was made during a tumultuous period of American history, which it seemingly ignored. The war in Vietnam was already a highly divisive issue and was spiralling into a crisis. The <a href="https://www.britannica.com/topic/Tet-Offensive">Tet offensive</a>, which began on January 31 1968, had claimed tens of thousands of lives. As US involvement in Vietnam escalated, domestic unrest and violence at home intensified. Increasingly, young Americans expected their artists to address the chaos that roared around them. But in exploring the origins of humanity’s propensity for violence and its future destiny, 2001 dealt with the big questions and ones that were burning at the time of its release. They fuelled what Variety magazine called the “coffee cup debate” over “what the film means”, which is still ongoing today. The design of the film has touched many other films. Silent Running by Douglas Trumbull (who worked on 2001’s special effects) owes the most obvious debt but Star Wars would be also unthinkable without it. Popular culture is full of imagery from the film. The <a href="https://faroutmagazine.co.uk/stanley-kubrick-2001-a-space-odyssey-music/">music</a> Kubrick used in the film, especially Strauss’s The Blue Danube, is now considered <a href="https://theweek.com/articles/702734/planetarium-brief-history-space-music">“space music”</a>. Images from the movie have appeared <a href="https://www.youtube.com/watch?v=kfK9pEQZyy0">in iPhone adverts</a>, in The Simpsons and even the trailer for the new <a href="https://metro.co.uk/2022/12/16/trailer-for-greta-gerwigs-barbie-spoofs-classic-film-in-best-way-17951854/">Barbie movie</a>. <figure><iframe src="https://www.youtube.com/embed/8zIf0XvoL9Y?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>2001: A Space Odyssey’s influence on this Barbie movie trailer couldn’t be more obvious.</figcaption></figure> The warnings of the danger of technology embodied in the film’s murderous supercomputer HAL-9000 can be felt in the “tech noir” films of the late 1970s and 1980s, such as Westworld, <a href="https://theconversation.com/how-alien-mutated-from-a-sci-fi-horror-film-into-a-multimedia-universe-204567">Alien</a>, Blade Runner and Terminator. HAL’s single red eye can be seen in the children’s series, Q Pootle 5, and Pixar’s animated feature, Wall-E. HAL has become shorthand for the untrammelled march of artificial intelligence (AI). In the age of ChatGPT and other AI, the metaphor of Kubrick’s computer is <a href="https://www.nytimes.com/2023/02/22/movies/ai-movies-microsoft-bing-robots.html">frequently evoked</a>. But why when there have been so many other images such as Frankenstein, Prometheus, terminators and other murderous cyborgs? Because there is something so uncanny and human about HAL who was deliberately designed to be more <a href="https://www.tandfonline.com/doi/abs/10.1080/01439685.2017.1342328?journalCode=chjf20">empathic and human than the people in the film</a>. In making 2001, Stanley Kubrick created a cultural phenomenon that continues to speak to us eloquently today.<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/209152/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/nathan-abrams-122305">Nathan Abrams</a>, Professor of Film Studies, <a href="https://theconversation.com/institutions/bangor-university-1221">Bangor University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Virgin Galactic’s use of the ‘Overview Effect’ to promote space tourism is a terrible irony

<a href="https://theconversation.com/profiles/ariane-moore-1060920">Ariane Moore</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> Virgin Galactic, the space tourism company founded in 2004 by Richard Branson, <a href="https://www.virgingalactic.com/">promotes its flights</a> as offering: <blockquote> A Brand New Perspective: Deepen your connection to Earth and to humanity with the transformational experience known as the Overview Effect. </blockquote> First discussed in 1987 by space philosopher Frank White, the Overview Effect is a result of viewing Earth from space. Expressions of the effect range broadly. Astronauts might experience profound awe and wonder at the perception of Earth as a fragile living being. Some suffer crushing grief when considering the harm humans inflict on nature. While Virgin Galactic promotes access to the Overview Effect as a major drawcard, it is a terrible irony that space tourism is <a href="https://www.thespacereview.com/article/4527/1">enormously damaging</a> for the environment. <figure><iframe src="https://www.youtube.com/embed/Z6d7hyW5FDw?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>On May 25, Virgin Galactic completed a final test flight before it starts taking paying customers.</figcaption></figure> <h2>The Overview Effect</h2> The Overview Effect is not limited to astronauts from the West. Their Chinese and Russian counterparts have described the same profound connection to Earth when witnessing the planet from space. As Soviet Russian cosmonaut Yuri Artyushkin <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2Fcns0000086">reported</a>: <blockquote> The feeling of unity is not simply an observation. With it comes a strong sense of compassion and concern for the state of our planet and the effect humans are having on it. It isn’t important in which sea or lake you observe a slick of pollution, or in the forests of which country a fire breaks out, or on which continent a hurricane arises. You are standing guard over the whole of our Earth. </blockquote> Until recently, researching the Overview Effect has required interviews with professional astronauts. Today, commercial space tourism is increasing awareness of the phenomenon, particularly when experienced by celebrities with large platforms. In 2021, Star Trek actor William Shatner completed a suborbital flight with Jeff Bezos’ space tourism company <a href="https://www.blueorigin.com/">Blue Origin</a>. Shatner had anticipated emotions of celebration and joy when viewing “<a href="https://www.nytimes.com/2021/10/13/science/bezos-shatner-star-trek.html">mother and Earth and comfort</a>” from space. Instead, he <a href="https://variety.com/2022/tv/news/william-shatner-space-boldly-go-excerpt-1235395113/">later wrote</a>, he struggled with “the strongest feelings of grief I have ever encountered”. Shatner attributed his experience to the Overview Effect. <h2>Space flight has a huge environmental impact</h2> Virgin Galactic promotes the Overview Effect on its <a href="https://www.virgingalactic.com/">homepage</a> as an experience exclusive to space flight. However, access is extremely costly. While an eager space tourist consents to parting with US$450,000 to experience a profound connection with Earth, the planet itself has no say in receiving the massive pollution a single trip produces. Rocket emissions impact Earth’s atmosphere, temperatures and the ozone layer at an unprecedented level. A <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2021EF002612">2022 study</a> found space tourism produces black carbon particles that are almost 500 times more efficient at warming the atmosphere than all surface and airline sources of soot combined. After being released into the upper atmosphere, the black carbon particles circulate for <a href="https://www.cnbc.com/2021/08/27/how-blue-origin-spacex-virgin-galactic-space-race-could-impact-the-atmosphere.html#:%7E:text=Experiencing%20a%20few%20minutes%20of,plane%20continuously%20for%20about%20three">four to five years</a> in a fine layer. This acts as a thin black umbrella <a href="https://www.cnbc.com/2021/08/27/how-blue-origin-spacex-virgin-galactic-space-race-could-impact-the-atmosphere.html#:%7E:text=Experiencing%20a%20few%20minutes%20of,plane%20continuously%20for%20about%20three">absorbing solar radiation while blocking it from reaching Earth’s surface</a>. A 1.5-hour Virgin Galactic flight generates emissions <a href="https://www.nsr.com/space-com-the-rise-of-space-tourism-could-affect-earths-climate-in-unforeseen-ways-scientists-worry/">equivalent to a ten-hour trans-Atlantic commercial air flight</a>. However, the latter carries hundreds of passengers. With a passenger limit of six, a Virgin Galactic launch <a href="https://theconversation.com/tourisme-spatial-quand-les-plaisirs-de-quelques-uns-polluent-la-planete-de-tous-146552">emits 4.5 tonnes of carbon per person</a>. That’s more than twice the Paris Agreement’s recommended annual individual carbon budget. Space tourism rocket launches don’t currently compare to commercial airline flights in number. But the suborbital transportation and space tourism market is expected to be worth <a href="https://www.prnewswire.com/news-releases/outlook-on-the-sub-orbital-transportation-and-space-tourism-global-market-to-2031---featuring-blue-origin-spacex-and-virgin-galactic-among-others-301333701.html">US$2.58 billion by 2031</a>. It’s growing at an annual rate of 17.15%. Virgin Galactic is aiming to launch <a href="https://www.cnbc.com/2020/11/06/virgin-galactic-each-spaceport-is-1-billion-annual-revenue-opportunity.html">400 space tourism flights every year</a>. <figure><iframe src="https://www.youtube.com/embed/1SJ1ENmfgmE?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>In this video on its website, Virgin Galactic uses the Overview Effect to promote its space tourism business.</figcaption></figure> <h2>Caring for Earth doesn’t depend on space flight</h2> The desirability of the Overview Effect is not the overwhelming emotions experienced when witnessing Earth from space. As was evident in Shatner’s feelings of immense grief, these emotions are not always pleasant. Instead, researchers, astronauts and space philosophers are interested in the spontaneous and powerful awareness that occurs. Astronauts’ accounts of the moment vary, but a consistent theme emerges: a connection to planet Earth that inspires environmental care. Importantly, such clarity can be achieved without a suborbital space flight. <a href="https://www.google.com.au/books/edition/The_Overview_Effect/3a2rz-s3JJsC?hl=en">Frank White argues</a> that, while viewing Earth from space produces the “ultimate” Overview Effect, it might also be had while looking at landscapes from a great height – such as a mountain range. Commercial pilots flying at high altitudes have experienced similar phenomena. And for those considering a Virgin Galactic flight, there are no guarantees. Many astronauts with long careers <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2Fcns0000086">report</a> never experiencing the Overview Effect. <figure class="align-center "><img src="https://images.theconversation.com/files/530799/original/file-20230608-27-brv39q.jpg?ixlib=rb-1.1.0&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/530799/original/file-20230608-27-brv39q.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=600&fit=crop&dpr=1 600w, https://images.theconversation.com/files/530799/original/file-20230608-27-brv39q.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=600&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/530799/original/file-20230608-27-brv39q.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=600&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/530799/original/file-20230608-27-brv39q.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=755&fit=crop&dpr=1 754w, https://images.theconversation.com/files/530799/original/file-20230608-27-brv39q.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=755&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/530799/original/file-20230608-27-brv39q.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=755&fit=crop&dpr=3 2262w" alt="View of whole Earth photographed by the orbiting Apollo 17 mission and dubbed 'Blue Marble'" /><figcaption>Being able to see the whole Earth from space was regarded as a transformative moment, but people can have environmental epiphanies without flying into space. <a class="source" href="https://www.nasa.gov/content/blue-marble-image-of-the-earth-from-apollo-17">NASA/Apollo 17</a></figcaption></figure> <h2>Environmental epiphanies happen on Earth</h2> Spontaneous clarity about the importance of nature can occur while standing on solid ground. “<a href="https://www.jstor.org/stable/26506666#:%7E:text=The%20working%20definition%20of%20Environmental,shifts%20in%20a%20meaningful%20manner.">Environmental epiphanies</a>” are well documented and have no connection to specific religious or cultural beliefs. Involving profound emotions and sudden awareness similar to the Overview Effect, environmental epiphanies can be accessed for free in mundane locations – such as reading a book at home. And, like the Overview Effect, environmental epiphanies can lead to lasting change. As space tourism continues to “take off”, misaligned marketing tactics like Virgin Galactic’s promotion of the Overview Effect must be scrutinised. Being launched into space – and the massive pollution the process creates – isn’t necessary for us to want to sustain our Earth.<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/206868/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/ariane-moore-1060920">Ariane Moore</a>, PhD Candidate in Philosophy, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

6 household items to complete your space

Forget perfect furnishings and decorations and focus on the household items that are easy to forget. 1. A comfy seat As basic as it sounds, it is definitely a necessity. We all do a lot of sitting at home so make sure you invest in a nice, comfy chair or fold-out sofa that won’t hurt your back. 2. A lamp Power outages can and do happen, so make sure you’re prepared with a torch or solar-powered lamp. You’ll thank yourself during an emergency! 3. A shower curtain Buy a fresh shower curtain and experiment with different colours. You could also match the colour of your shower curtain, towels and floor mat to really bring the room together. 4. A good mattress This one is so obvious, but have you bought the right size? Is it good quality? You spend around a third of your life asleep, so make sure you get a good one. A mattress should be more of an investment than a simple purchase. 5. Kitchen utensils Prepare yourself to cook! Make sure you have a wooden spoon, a spatula and basic cutlery. Invest in a fry pan and some saucepans too. 6. Potted plants Your home is going to feel fresh and healthy with a few indoor plants around. They will help clean the air and add a little style to your room as well. Image credit: Shutterstock

Humans are still hunting for aliens. Here’s how astronomers are looking for life beyond Earth

We have long been fascinated with the idea of alien life. The earliest written record presenting the idea of “aliens” is seen in the satiric work of Assyrian writer <a href="https://blogs.scientificamerican.com/life-unbounded/the-first-alien/">Lucian of Samosata</a> dated to 200 AD. In one novel, Lucian <a href="https://www.yorku.ca/inpar/lucian_true_tale.pdf">writes of a journey to the Moon</a> and the bizarre life he imagines living there – everything from three-headed vultures to fleas the size of elephants. Now, 2,000 years later, we still write stories of epic adventures beyond Earth to meet otherworldly beings (<a href="https://www.britannica.com/topic/The-Hitchhikers-Guide-to-the-Galaxy-novel-by-Adams">Hitchhiker’s Guide</a>, anyone?). Stories like these entertain and inspire, and we are forever trying to find out if science fiction will become science fact. <h2>Not all alien life is the same</h2> When looking for life beyond Earth, we are faced with two possibilities. We might find basic microbial life hiding somewhere in our Solar System; or we will identify signals from intelligent life somewhere far away. <div data-id="17"> </div> Unlike in <a href="https://www.britannica.com/topic/Star-Wars-film-series">Star Wars</a>, we’re not talking far, far away in another galaxy, but rather around other nearby stars. It is this second possibility which really excites me, and should excite you too. A detection of intelligent life would fundamentally change how we see ourselves in the Universe. In the last 80 years, programs dedicated to the search for extraterrestrial intelligence (SETI) have worked tirelessly searching for cosmic “hellos” in the form of radio signals. The reason we think any intelligent life would communicate via radio waves is due to the waves’ ability to travel vast distances through space, rarely interacting with the dust and gas in between stars. If anything out there is trying to communicate, it’s a pretty fair bet they would do it through radio waves. <h2>Listening to the stars</h2> One of the most exciting searches to date is <a href="https://breakthroughinitiatives.org/initiative/1">Breakthrough Listen</a>, the largest scientific research program dedicated to looking for evidence of intelligent life beyond Earth. This is one of many projects funded by US-based Israeli entrepreneurs Julia and Yuri Milner, with some serious dollars attached. Over a ten-year period a total amount of <a href="https://breakthroughinitiatives.org/initiative/1">US$100 million</a> will be invested in this effort, and they have a mighty big task at hand. Breakthrough Listen is currently targeting the closest one million stars in the hope of identifying any unnatural, alien-made radio signals. Using telescopes around the globe, from the 64-metre Murriyang Dish (Parkes) here in Australia, to the 64-antenna MeerKAT array in South Africa, the search is one of epic proportions. But it isn’t the only one. Hiding away in the Cascade Mountains north of San Francisco sits the <a href="https://www.seti.org/ata">Allen Telescope Array</a>, the first radio telescope built from the ground up specifically for SETI use. This unique facility is another exciting project, able to search for signals every day of the year. This project is currently upgrading the hardware and software on the original dish, including the ability to target several stars at once. This is a part of the non-profit research organisation, the SETI Institute. <h2>Space lasers!</h2> The SETI Institute is also looking for signals that would be best explained as “space lasers”. Some astronomers hypothesise that intelligent beings might use massive lasers to communicate or even to propel spacecraft. This is because even here on Earth we’re investigating <a href="https://www.nasa.gov/feature/goddard/2022/the-future-of-laser-communications/">laser communication</a> and laser-propelled <a href="https://www.insidescience.org/news/new-light-sail-design-would-use-laser-beam-ride-space">light sails</a>. To search for these mysterious flashes in the night sky, we need speciality instruments in locations around the globe, which are currently being developed and deployed. This is a research area I’m excited to watch progress and eagerly await results. As of writing this article, sadly no alien laser signals have been found yet. <h2>Out there, somewhere</h2> It’s always interesting to ponder who or what might be living out in the Universe, but there is one problem we must overcome to meet or communicate with aliens. It’s the speed of light. Everything we rely on to communicate via space requires light, and it can only travel so fast. This is where my optimism for finding intelligent life begins to fade. The Universe is big – really big. To put it in perspective, humans started using radio waves to communicate across large distances in 1901. That <a href="https://ethw.org/Milestones:Reception_of_Transatlantic_Radio_Signals,_1901">first transatlantic signal</a> has only travelled 122 light years, reaching just 0.0000015% of the stars in our Milky Way. Did your optimism just fade too? That is okay, because here is the wonderful thing… we don’t have to find life to know it is out there, somewhere. When we consider the <a href="https://theconversation.com/how-many-stars-are-there-in-space-165370">trillions of galaxies</a>, septillion of stars, and likely many more planets just in the observable Universe, it feels near impossible that we are alone. We can’t fully constrain the parameters we need to estimate how many other lifeforms might be out there, as famously proposed by Frank Drake, but using our best estimates and <a href="https://www.cambridge.org/core/journals/international-journal-of-astrobiology/article/numerical-testbed-for-hypotheses-of-extraterrestrial-life-and-intelligence/0C97E7803EEB69323C3728F02BA31AFA">simulations</a> the current best answer to this is tens of thousands of possible civilisations out there. The Universe <a href="https://theconversation.com/is-space-infinite-we-asked-5-experts-165742">might even be infinite</a>, but that is too much for my brain to comprehend on a weekday. <h2>Don’t forget the tiny aliens</h2> So, despite keenly listening for signals, we might not find intelligent life in our lifetimes. But there is hope for aliens yet. The ones hiding in plain sight, on the planetary bodies of our Solar System. In the coming decades we’ll explore the moons of Jupiter and Saturn like never before, with missions hunting to find traces of basic life. Mars will continue to be explored – eventually by humans – which could allow us to uncover and retrieve samples from new and unexplored regions. Even if our future aliens are only tiny microbes, it would still be nice to know we have company in this Universe.

Australia’s top towns revealed

A study has compared 752 small Australian towns and crowned the 36 at the top of the pack. The study was <a href="https://www.theaustralian.com.au/inquirer/australias-best-towns-kiama-margaret-river-shoalhaven-among-the-top-places-to-live/news-story/695405e2e1787d67e64a93495a6cb8e6">published by The Australian</a>, and saw demographer Bernard Salt consider criteria such as unemployment, diversity, median income, technical skill, and education across the 752 towns in his mission to declare the best of the best in each Australian state and territory. More specifically, Salt looked at towns that: <ul> <li dir="ltr" aria-level="1"> Earn more than $1,282 per a week household median income </li> <li dir="ltr" aria-level="1"> Less than 5.1 per cent unemployment </li> <li dir="ltr" aria-level="1"> More than 15 per cent attained university education </li> <li dir="ltr" aria-level="1"> More than 36 per cent with technical (trade) skill </li> <li dir="ltr" aria-level="1"> More than 12 per cent workforce owner/manager </li> <li dir="ltr" aria-level="1"> No less than 14 per cent born overseas </li> <li dir="ltr" aria-level="1"> At least 17 per cent volunteer </li> <li dir="ltr" aria-level="1"> At least 14 per cent provide unpaid care e.g., for example to a relative </li> <li dir="ltr" aria-level="1"> More than 59 per cent have no long-term health condition </li> <li dir="ltr" aria-level="1"> More than 6.5 hours per a week in unpaid domestic housework </li> </ul> Salt’s findings revealed a town in each state and territory that was “drawn from a list of 36 finalists that survive most of the filters”, and ultimately declared to be a step above the rest. For Queensland, Tamborine Mountain came out on top. For the Northern Territory, it was Nhulunbuy. For South Australia, Mount Barker. Western Australia, Dunsborough. Victoria, Bright. Tasmania, Legana. And last but not least, Kiama took the trophy for New South Wales, as well as bragging rights as “the standout overall.” “In the modern era, say the 2020s and beyond, I think that small-town Australia, as well as big-city Australia, needs skills, training, entrepreneurial energy and a measure of diversity to deliver opportunity to residents,” said the founder of The Demographics Group. “What this exercise shows is that across the continent Australians want more or less the same thing when it comes to living in a small town,” Salt went on, “proximity to a capital or major regional city; a tree-change or a sea-change environment; or, better still, all three criteria jammed within a single location offering views and amenity.” “The Australian people have spoken through their collective responses to the census,” he concluded. “Sea-change, tree-change, big-city access and a place of their own within which they can potter about and steadily make improvements, while also volunteering, caring, and making a contribution to the local community. That is the essence of small-town Australia. “And of course if you disagree with the metrics and the logic of how the top towns were selected, then you are free to <a href="https://www.theaustralian.com.au/inquirer/top-towns">jump on to the website</a>, access the model, switch around the metrics and come up with your own version of Australia’s top towns. Hours of fun for the demographically inclined.” Images: Getty

Melissa Caddick's luxury items auctioned off for a small fortune

Luxurious jewellery dripping with diamonds, prized art and designer handbags all once owned by Melissa Caddick have recently been sold for a fraction of what Caddick was believed to have swindled. The items were sold off piece by piece and the proceeds have been used to repay some of the $23 million that Caddick was accused of stealing from investors in an elaborate Ponzi scheme before her disappearance in November 2020. The final hammer fell on the catalogue of "luxury goods", according "strong interest" from the public driving the total amount raised to $860,000 over three auctions. "The sale of these items represents completion of significant personal assets of the Receivership and our aim was to get this completed before the end of 2022," Principal at Jones Partners, Bruce Gleeson, said. "In particular, the overall prices achieved for the designer clothing and luxury goods and jewellery reflect the strong interest in the various items, specifically the Canturi jewellery collection." From the Canturi collection, Caddick's famous black sapphire and diamond "Stella" necklace with matching earrings, originally valued by auctioneers between $80,000 and $120,000, sold for $130,000.

5 ways to save space at home

Although many of us enjoy a good de-cluttering, a more pressing problem can be finding somewhere to put the items that you decide to keep. Many homes lack the space for things that use to come standard such as linen cupboards and storage cupboards. In a lot of homes, built in wardrobes are seen as an optional extra rather than a must-have. Which means a lot of your treasure doesn’t have a permanent place to reside. Try some of our space saving ideas today, which can help you tidy away the bits and pieces that need a home. Utilise space under the bed Instead of letting dust set up house under there, invest in some plastic tubs that fit under your bed. Fill them with anything from sheets and blankets to shoes and hats. Install a low bookshelf underneath windows The area under a window is often wasted space. A small bookshelf there can hold books, games, photo albums, or even a stereo. Visit a home hardware store and look for DIY shelves. Make your bathroom mirror into a cupboard If you just have a standard mirror fitted, you could be missing out on a great spot to store your toiletries. A bathroom cabinet is not too expensive and means your basin is free of clutter. Use space saver bags to store off-season clothes These nifty little bags shrink clothes right down simply by using a vacuum cleaner to remove the air that takes up valuable space. Available from most discount stores, you can also use them for things like doonas and blankets that can take up lots of room in your linen cupboard. Add a shelf above doorways Another underutilised spot, the area above doors (especially hallways) is perfect for storing things like books or CDs. Check first that the wall is able to support a shelf before you start drilling. Image: Getty Images
