Rijo Stephen Cletus: We got some key things wrong about long COVID. Here are 5 things we've learnt

We got some key things wrong about long COVID. Here are 5 things we've learnt

In late 2020 as we hid from COVID behind the moat of “fortress Australia”, we started to hear that in some people, COVID symptoms persisted for months. They were called “long haulers” or had “long COVID”.

Contrary to what we’d expected, it wasn’t just affecting people’s lungs or breathing. Long haulers were experiencing an enormous range of other symptoms: fatigue that was worse after activity, muscle aches and pains, headache, and cognitive dysfunction or brain fog.

Why do we stop exploring new music as we get older?

According to an estimate from the International Federation of the Phonographic Industry, an organisation that represents the international music industry, people around the world spend on average 20.1 hours per week listening to music, up from 18.4 hours in 2021.

We have more ways to access music than at any time in history and a whole world of unfamiliar styles to explore.

Would a nature repair market really work? Evidence suggests it's highly unlikely

Why should governments do all of the heavy lifting to arrest the steep decline of many ecosystems? Endangered species live on private land too – so why not give farmers and landholders incentives to look after them and restore habitat?

Framed like this, it’s easy to see the appeal of nature repair markets. Harness private money and direct it towards rescuing nature. No wonder the Albanese government is forging ahead with its nature repair market bill and seeking public submissions. If it becomes law, landholders will be able to gain tradeable biodiversity certificates for projects that protect, manage and restore nature.

Labor's lead drops in Resolve and Essential polls, but they are still far ahead

Election Analyst (Psephologist) at The Conversation; and Honorary Associate, School of Mathematics and Statistics, The University of Melbourne

A federal Resolve poll for Nine newspapers, conducted February 15-19 from a sample of 1,604, gave Labor 40% of the primary vote (down two since January), the Coalition 31% (up two), the Greens 10% (down one), One Nation 5% (down one), the UAP 1% (down one), independents 9% (up one) and others 2% (steady). Two points were lost to rounding.

'Special thanks': how comic book writers and artists are forgotten during the superhero film boom

When the new creative head of DC Studios, James Gunn, announced their upcoming slate of films and TV, it included many names you might expect: Superman, Batman, maybe even Swamp Thing.

It also included some lesser-known and leftfield picks, such as the take-no-prisoners superhero team The Authority. The team’s co-creator, artist Bryan Hitch, found that out when everyone else did. “The Authority…?” he tweeted. “I’m glad someone told me…”

Landslides and law: Cyclone Gabrielle raises serious questions about where we've been allowed to build

Given the death toll, it’s important we consider the impacts of Cyclone Gabrielle sensitively. But we must also begin looking into the history of land-use and planning decisions in areas worst hit by landslides.

One such area is the beach community at Muriwai in West Auckland, where two volunteer firefighters were tragically killed in a landslide.

Ride-share companies are losing billions, so why their interest in unprofitable public transport?

Why do Uber, Lyft, Didi, OLA and other ride-sharing companies want to partner with public transport agencies? For Uber and Lyft, the reason is simple: their business plans were based on eventually using driverless vehicles to eliminate their main cost, the labour cost of the driver. But human drivers won’t be replaced for some time.

While many of these companies have raised lots of cash from venture capitalists, they are burning though it at an alarming rate. Uber made a loss of US$8.8 billion in 2022. Lyft, Uber’s main competitor in the United States, lost US$1.28 billion.

This is not the same virus that causes genital herpes, HSV-2, which is present in about 13% of people worldwide.

As veganism grows in popularity, some people are still eating meat with friends - could a 'social omnivore' diet work for you?

It’s Sunday and your family are sat around the dinner table. There’s a bird roast, gravy and then there’s your vegan brother Tom. Your mum’s upset that he will not try a bit of the gravy on his vegetables and Grandpa is surprised that chicken even counts as meat.

We can be certain that the dinner conversation will soon circle around to how “normal, nice, necessary and natural” meat eating is. These are the four main rationalisation strategies that omnivores use to defend their dietary choices.

Morning exercise burns more body fat, mouse study shows

Our latest study found that when mice did a single exercise session in the late morning (around three hours after waking up), they burned more adipose tissue (body fat) compared to mice who exercised in the late evening. Along with this, we saw changes in the way adipose tissue genes respond following exercise.

Using mice to gather evidence about what happens in our own physiology is common because almost every set of genes in humans has a closely related form in mice. This makes it likely that the effects we observe in mice may be similar to what we’d expect to see in humans.

My child is in a composite class this year. Is this a good thing?

The majority of classes in Australian primary school are made up of children from the same grade. The philosophy behind this is students of similar ages are grouped together to align with similar stages of learning development.

But composite classes – also called “multi-age” or “split year” – are also common. For example, in New South Wales last year, one quarter of classes in state schools had composite groupings. These combine different grades into one class, usually two consecutive grades, say a Year 1 and a Year 2.

Decriminalizing hard drugs in B.C. will help reduce the stigma of substance abuse

Unlike other physical and mental health conditions, however, substance use disorder — or addiction — has historically been seen as a moral failing and was for many years relegated to the fringes of the medical community.

Instead of receiving treatment in an accessible medical setting, many individuals went untreated or turned to a largely unregulated system of public and private treatment options. Drug use was criminalized and because many still believe that people who use drugs are engaging in deliberately deviant behaviour, we often choose to punish, rather than treat, drug addiction.

Epigenetic and social factors both predict aging and health - but new research suggests one might be stronger

While each person has a genetic makeup that largely does not change over their lifetime, chemical changes to their genetic material that occur throughout life can change which genes are turned on or off and lead to more rapid aging. These changes typically involve the addition of methyl groups to DNA and are influenced by social and environmental exposures, such as adverse childhood experiences, smoking, pollution and depression.

In 2013, geneticist and biostatistician Steve Horvath introduced the idea that a person’s rate of aging would be captured by the level of methylation in their genome. He also developed ways to measure epigenetic age in terms of years and compare this age to one’s chronological age.

When journalist and writer Kate Legge first let her ex-husband read her work on infidelity – his infidelity (particularly with “a close girlfriend” of Legge’s, but also more wide-ranging) – he thought she was too judgemental. But the book she eventually published, Infidelity and Other Affairs, is a wonderfully thoughtful, mature and somewhat eclectic exploration of the breakdown of a marriage and Legge’s endurance through and beyond it.

Pandemic finger-pointing: New research sheds light on who Canadians blame in times of crisis

How your brain decides what to think

You’re sitting on the plane, staring out of the window at the clouds and all of a sudden, you think back to how a few months ago, you had a heart-to-heart with a good colleague about the pressure you experience at work. How do thoughts seemingly completely unrelated to the present pop into our heads? Why do we remember certain things and not others? Why does our mind go off on tangents and why do we have daydreams?

Underlying these processes is a shared pattern of common brain activity, in regions which together make up the “default mode network”, discovered and named by neurologist Marcus Raichle in the early 2000s. It’s engaged when we are daydreaming, thinking about ourselves or others, recalling memories, or imagining future events.

3 things the pandemic taught us about inequality in college -- and why they matter today

Elise, a nursing student at an elite U.S. university in the Northeast, found herself back home and sleeping on the floor of her parents’ one-bedroom apartment after the COVID-19 pandemic was declared in March 2020.

It was tough to get a good night’s sleep as family members passed through to the kitchen or the front door. Such interruptions also made it difficult to concentrate during lectures and exams. Sometimes, limited internet bandwidth made it impossible for Elise to attend class at all. She couldn’t ask her parents to buy her a new computer to replace the one that was breaking down, she explained, because she knew they couldn’t afford it.

It is small and inconspicuous, yet nothing seems to stop its expansion. From its native habitat in the nooks and crannies of caldera rocks in the highlands of Madeira and the Canary Islands, to feeding on shrews, bats and lizards in the suburbs of London and Dublin, the noble false widow spider (Steatoda nobilis) is a threat to ecosystems that you’d probably overlook.

Roald Dahl rewrites: rather than bowdlerising books on moral grounds we should help children to navigate history

Although several of his best-known children’s books were first published in the 1960s, Roald Dahl is among the most popular authors for young people today. The recent decision by publisher Puffin, in conjunction with The Roald Dahl Story Company, to make several hundred revisions to new editions of his novels has been described as censorship by Salman Rushdie and attracted widespread criticism.

The changes, recommended by sensitivity readers, include removing or replacing words describing the appearance of characters, and adding gender-neutral language in places. For instance, Augustus Gloop in Charlie and the Chocolate Factory is no longer “fat” but “enormous”. Mrs Twit, from The Twits, has become “beastly” rather than “ugly and beastly”. In Matilda, the protagonist no longer reads the works of Rudyard Kipling but Jane Austen.

Much Ado About Nothing: National Youth Theatre gives Shakespeare the Love Island treatment

“What’s your type on paper?” is frequently asked by contestants on the popular reality dating show Love Island. “Rich, that’s certaine” responds Benedick, a contestant on “Nothing Island”, who appears to know exactly what he likes. “Wise, or I’ll none”, “virtuous”, “fair”, “mild” – though he concedes he is not fussed about hair colour.

In this National Youth Theatre production celebrating their tenth anniversary, poet and playwright Debris Stevenson (Poet in Da Corner) adapts Shakespeare’s Much Ado About Nothing as the final segment of reality TV show “Nothing Island”. “If it ain’t love,” executive producer Leonato (Jessica Enemokwu) says: “it’s Nothing”.

How queuing leads to city centre violence and what our research says about preventing night-time brawls

People go out at night because they want to socialise, drink and be entertained. Unfortunately, all too often that leads to violent behaviour in our towns and city centres. But the events that lead to such violence are poorly understood.

We set out to explore some of the possible explanations of night-time violence using data on Cardiff city centre footfall (the number of people in the city centre) and assault-related attendances at the nearby University Hospital of Wales. We found that a break down in the unwritten etiquette of queuing may be one of the reasons behind increases in violence at night.

In the far from diverse publishing industry, sensitivity readers are vital

Sensitivity readers are contracted by a publisher to provide editorial feedback on omissions, discontinuity, cliche and credibility issues in a book draft – specifically where they relate to subject matter about people from marginalised groups.

Presidential greatness is rarely fixed in stone - changing attitudes on racial injustice and leadership qualities lead to dramatic shifts

Every American president has landed in the history books. And historians’ assessments of their performance have been generally consistent over time. But some presidents’ rankings have changed as the nation – and historians themselves – reassessed the country’s values and priorities.

Historians have been ranking presidents in surveys since Arthur Schlesinger Sr.’s first such study appeared in Life magazine in 1948. The results of that survey categorized Presidents Abraham Lincoln, George Washington, Franklin D. Roosevelt, Woodrow Wilson, Thomas Jefferson and Andrew Jackson as “great.”

The Best Fossils for Your Buck

Fossil collecting doesn’t have to be the élitist hobby that it’s often perceived as. So your bid of fifty dollars was just shy of the $6.1-million hammer price of the T. rex skull sold at Sotheby’s this December. Sure, it stings, especially because you were outbid by both Leonardo DiCaprio and Nicolas Cage on that other dino skull a few years back. But, for the thrifty fossil hunter, there are plenty of affordable options if you know where to look.

A small piece of amber with a fossilized mosquito suspended in it. That’s $18.02 on Etsy. This starter fossil is also an investment piece: in sixty-five million years’ time, DNA from this mosquito can be used to create actual living dinosaurs, which can be kept in an amusement park on a distant tropical island.

A year on, Russia's war on Ukraine threatens to redraw the map of world politics - and 2023 will be crucial

Wars are world-shaping. Beyond their immediate human and physical tolls, wars alter the fates of societies and states; of clans, cultures and leaders. They establish new lines of access to resources and influence, determining who has what – and who doesn’t. They set precedents for how future wars are justified and, in the case of attempted conquest, wars can ultimately redraw the map of world politics.

One year after its unprovoked invasion on February 24, 2022, Russia’s war against Ukraine encompasses all these dangers.

This comes after Germany and the US finally agreed to give more than 300 heavy tanks to Ukraine after much debate.

Some observers have focused on whether providing increasingly sophisticated weaponry is a good idea for strategic reasons, such as whether it risks further escalating the conflict.

Banshees of Inisherin: how location and language have set the scene for Ireland's vibrant film industry

From classic western films onwards, many cinematographers have made use of far flung places to transport viewers to other worlds and different times.

Stories inspired by the west of Ireland have benefited from the beautiful visage that its landscape provides. John Ford’s The Quiet Man (1952) showcased the rolling hills of Connemara as the mise-en-scène for his award-winning romantic comedy drama. Tourists still come in search of Sean Thornton’s house, travelling along Ireland’s Atlantic edge to see what remains of the “old way of life”.

Ghana wants fewer polluting old cars on the road. But it's going about it the wrong way

Only so many of the vehicles in circulation are, however, exchanged and destroyed or recycled. A good number of them are exported to Africa and other low-income regions of the world for reuse.

ChatGPT and Tinder: do smart chatbots make dating online better or worse?

Tinder and other dating apps have come to define modern dating, and notoriously so. Users download the Tinder app to their phones or other devices and can then view the profiles of potential dates nearby. If they think someone might be a match, they swipe to the right on their touchscreens to show interest. If the other person swipes right too, a chat can begin, which might lead to an in-person meeting.

This initial introduction involves minimal information – a photo and some basic details about yourself. The result is that romance and trust are sometimes assumed to be missing from the dating process. Added to this are fears of harassment and scams as well as uninspirational (and often sexually aggressive) Tinder opening lines like, “Wow, your clothes would look great bundled on my bedroom floor”. Yet, Tinder remains firmly part of the repertoire when looking for love, casual connections or intimacy.

The Poetry of Science: A Victorian Portal to Wonder

“Science describes accurately from outside, poetry describes accurately from inside,” Ursula K. Le Guin wrote in her wonderful meditation on subjectifying the universe. “Science explicates, poetry implicates. Both celebrate what they describe.”

We have a word for that common celebration: wonder — the sense that the world is strange and beautiful, and we are hovering on the edge between understanding and awe as we behold the naked poetry of reality.

A century and a half before Le Guin, a century and a half before the inception of The Universe in Verse, the polymathic scientist and poet Robert Hunt (September 6, 1807–October 17, 1887) explored the consonance and complementarity of these twin languages of wonder in his 1848 book The Poetry of Science; or, Studies of the Physical Phenomena of Nature (public library | public domain) — an ambitious summation of all the major discoveries of science to that point, from gravity and light to the molecular forces and the reproduction of plants, revealing the poetry and aesthetic ecstasy inside the scientific facts.

Research on teen social media use has a racial bias - studies of white kids are widely taken to be universal

We found that commonly accepted portrayals of teens online distort or obscure the experiences of teens of color. These teens often have different online experiences, face different harms and may be using social media to share and present underrepresented aspects of themselves and their experiences.

On the negative side, teens who are members of racial and ethnic minorities face discrimination online, including racial slurs or jokes, negative stereotyping, body shaming and even threats of harm. The first study of its kind to investigate the mental health implications of online discrimination for Black and Latino sixth through 12th graders over time found that these groups had increased risk of depression and anxiety.

The iconic outfits that cause outrage

Even if you have never watched Sex and the City, you probably still know that Carrie Bradshaw once wore a tutu. The look symbolised the TV show. But it could have been very different. The series writer and producer Darren Star didn't "get it", says the show's costume designer Patricia Field in her new book. "Who's going to understand this girl, in New York, in a tutu?" He wanted to put her in a powder blue frock for the opening credits instead.

It sums up the way many people feel about costumes created by Field, who has been responsible not only for the wardrobe of Sex and the City but also those of Ugly Betty, The Devil Wears Prada and Emily in Paris. The apparent randomness of the now-82-year-old New Yorker's ensembles, as well as their rollercoaster extremes, provoke a range of reactions in audience – delight, bafflement and even anger.

Will All Quiet on the Western Front win best picture Oscar?

Some of the nominations for best picture at this year's Oscars were easy to predict. The Fabelmans is the venerable Steven Spielberg's love letter to cinema, for instance, so that was a dead cert. Top Gun: Maverick was a commercial and critical smash, so that was always a shoo-in, too. But one film on the shortlist took pundits by surprise: All Quiet on the Western Front. Adapted from the classic World War One novel by Erich Maria Remarque, it was given a mere scattering of cinema showings before streaming on Netflix; it starred an Austrian actor, Felix Kammerer, who had never been in a film before; and its director, Edward Berger, had done most of his work in television. It was also German – and no previous German film had ever been in the running for best picture. Plenty of critics expected All Quiet on the Western Front to turn up on the best international feature list, but not only did it get a best picture nomination, it appeared in eight other categories, too. And then it won the best film award at the Baftas, and an initially overlooked film became a hot favourite. It was the biggest Oscar shock since Will Smith slapped Chris Rock in 2022.

Still, perhaps that's an outdated way of looking at it. The Oscars, and the film industry in general, have changed recently in all sorts of radical ways. And if you put those ways together, then suddenly Berger's epic war drama seems like the most logical best picture choice of all.

Debate: ChatGPT offers unseen opportunities to sharpen students' critical skills

As gloomy predictions foretell the end of homework, education institutions are hastily revising their policies and curricula to address the challenges posed by AI chatbots. It is true that the emergence of chatbots does raise ethical and philosophical questions. Yet, through their interactions with AI, people will inevitably enhance skills that are crucial in our day and age: language awareness and critical thinking.

Bruce Willis has frontotemporal dementia - here's what we know about the disease

In 2022, the 67-year-old action movie star was diagnosed with aphasia - difficulty with language and speech. Aphasia can occur for a variety of reasons (most commonly stroke) but for Willis, it is now clear that these speech problems were the early signs of this particularly devastating form of dementia.

Frontotemporal dementia is an umbrella term for any disease that causes gradual loss of brain tissue in the frontal and temporal lobes – the front and sides of the brain. Although relatively rare, it is one of the most common causes of dementia in people under the age of 65, accounting for around 40% of early-onset cases.

Is Artificial Light Poisoning the Planet?

Among the many looming ecological disasters that terrify us today, one that only a handful of people have contemplated as sufficiently looming and terrifying is the loss of the bats in our belfry. According to “The Darkness Manifesto” (Scribner), by the Swedish ecologist Johan Eklöf, most churches in southwest Sweden had bat colonies back in the nineteen-eighties, and now most of them don’t. Light pollution, his research suggests, has been a major culprit: “District after district has installed modern floodlights to show the architecture it’s proud of, all the while the animals—who have for centuries found safety in the darkness of the church towers and who have for 70 million years made the night their abode—are slowly but surely vanishing from these places.”

The presence of bats in the belfry, as a metaphor for disordered thinking, is usually taken to refer to the way bats would flutter around the upper stories of distressed churches, but a larger madness, Eklöf thinks, is responsible for their absence. A professor at Stockholm University, he is an expert in bats, which might suggest a déformation professionnelle in his interest in darkness, the way an expert in roosters might have a weakness for the dawn. He is able to tell us authoritatively that, though bats do indeed use natural sonar to echolocate their way around, their eyes see well enough in the dark to help in their navigation. (As so often, nature’s secret to survival is not one perfect plan but a little bit of this and a little bit of that.) Of course, Eklöf’s arguments escape the narrow world of roof eaves and pointy ears. Though the book is written as a sort of “Silent Spring” manifesto against the ecological devastations of light pollution, its considerable charm depends on the encyclopedic intensity with which he evokes the hidden creatures of the night.

Ukraine: 12 months at war - Biden visit to Kyiv sets the seal on a year of growing western unity and Russian isolation

Ukraine undoubtedly remains on top of the global political agenda. Not only did it dominate discussions at the Munich security conference, but the surprise visit of the US president, Joe Biden, to Kyiv sent an unmistakable message to Russia, and the rest of the world: the west stands with Ukraine and will not let Vladimir Putin get away with his violation of Ukraine’s sovereignty and territorial integrity.

What’s more, Biden’s visit also underscores that the west has every confidence that the Russian president will not win this war and is finally coming round to the idea of providing Ukraine with what it needs to defeat Russia.
