By writing a book about Korean myths, a writer learned that the old stories ran deep in her familyIn my childhood homes, I grew up with Korean culture all around me. For years we had a woodblock print of a tiger (intended to ward off evil spirits) on top of our bookcase, a print of the 10 symbols of longevity and a shamanic dance mask of a syphilitic monk mounted on our wall, ancient Silla-style and celadon pottery on a bookshelf and carved wooden wedding ducks on a side table. All of these things were like background noise to me - they were just normal.When I was an infant, my father would lift me up and chant the Korean phonemes, Ga, na, da, ra..." to me to ensure I would be able to pronounce all the sounds of the language. As I grew, he would sing me Korean children's songs and say rhymes. I still remember all the words to Mountain Rabbit and Forsythia. Sythia, sythia, forsythia, pluck one, put it in your mouth." Still, I used to have trouble pronouncing the plosive letters, of which there are no equivalent in English, and telling the difference between the short and long o" sounds. Continue reading...

Research at the Francis Crick Institute could lead to new drugs to counter progress of diseases like Alzheimer'sBritish scientists are about to launch a remarkable research project that will demonstrate how the air we breathe can affect our brains. This work will be vital, they say, in understanding a major medical problem: how atmospheric pollution can trigger dementia.In recent years, scientists have discovered that air pollution is one of the most pernicious threats to human health and have shown it is involved in causing cancer, heart disease, diabetes, low birthrates, and many health conditions.

The researcher spent 10 years studying how attitude affects mood and behaviour, and her new book shares ways in which we can learn to value the colder monthsKari Leibowitz holds a PhD in social psychology from Stanford University, where she studied the role of our mindsets on our health and wellbeing. For the past 10 years, Leibowitz has been investigating people's attitudes to winter and the ways they can powerfully affect our mood and behaviour - research that has culminated in her debut book, How to Winter: Harnessing Your Mindset to Thrive in Cold, Dark Or Difficult Times.As a Fulbright scholar, you moved from Atlanta to the University of Tromso in Norway. The polar night there lasts for almost two months. How did that experience inform your views of winter?

Recognized as a religion by the IRS, the group uses the religious right's tactics, and their victories, against themThe devil works hard, but the Republican party works harder. Not a day seems to go by without anti-abortion zealots on the right advancing some cunning new plan to strip women of their bodily autonomy. As well as shutting down abortion clinics, Republican states are trying to essentially outlaw abortion pills: on Friday, Missouri, Kansas and Idaho renewed a legal push to drastically reduce access to mifepristone.

Researchers hope to uncover how people died and how diseases have developed over 1,000 yearsDeep beneath the streets of Paris, thedead are having their last word. They are recounting 1,000 years of death in the city: how many are buried in the labyrinth of tunnels that make up Les Catacombes, what killed them and how the diseases that may have led to their demise have developed over the centuries.In the first ever scientific study of the site, a team of archeologists, anthropologists, biologists and doctors is examining some of the skeletons of an estimated 5-6 million people whose bones were literally dumped down quarry shafts at the end of the 18th century and beginning of the 19th.

From chaotic collisions to depletion of the ozone layer, the thousands of satellites in orbit around Earth have the potential to wreak havoc in coming decades. What are the solutions to a growing menace?Since the start of the space age, we've had a throwaway culture - a bit like plastics in the ocean," says Nick Shave, managing director of Astroscale UK, an in-orbit servicing company headquartered in Japan.Getting a satellite into orbit around the Earth used to be a big deal. From the launch of the first, Sputnik, in 1957, as it became easier and cheaper to put satellites into space, the numbers have boomed. In 2022, there were about 6,000 and by 2030, one estimate suggests there will be nearly 60,000 satellites in orbit around our planet. Continue reading...

Researchers urge caution after Jordan tomb excavation and say new clues about Nabataean culture may lie elsewhereFor one of the most famous ancient sites on the planet, there is a surprising amount about the city of Petra - and the Nabataean people who built it - that we don't know for sure.What exactly were their origins? How did their society operate? And why did they hand-carve such spectacular monuments into the reddish rock of the Jordanian desert? Continue reading...

Deborah Anna Luepnitz and Desmond Hewitt respond to Jacqueline Rose's article on the great psychoanalystI agree with Jacqueline Rose about Freud's continued relevance to our understanding of sexualities (What Sigmund Freud can teach us about the Middle East and #MeToo, 10 October). One could argue that the contemporary movement for marriage equality began with Freud, given his refusal to pathologise homosexuality. Many people assume that the Oedipus complex is meant to produce boys who will grow up loving women, and girls who will love men (I would call that Oedipus simplex").I wish Rose had mentioned what Freud called the complete Oedipus complex", which suggests that every child forms both same-sex and cross-sex attractions. Littleboys can have romantic feelings for Daddy as well as Mommy, as his famous case of Little Hans showed. For whatever reason, it does seem to be true that younger people are giving Freud a second look. In the past five years, 12 universities in the US have made it possible for students to obtain aminor - study a secondary subject - in psychoanalytic studies". At the University of Pennsylvania,whereIhave taught, these courses are attracting a surprising number of students.

Study finds that breaking up your exercise is more effective, but Tim Dowling remains to be convincedLet me start by saying that I am not looking for ways to be more tired. I'm tired enough. However, a study suggesting that exercise punctuated by frequent breaks requires more energy than steady-state" exertion has a certain counterintuitive attraction: I can exercise better by resting more.The results of the study, published in Proceedings of the Royal Society B, are striking. Volunteers on treadmills and stair climbers used 20-60% more oxygen when walking in bursts of 10-30 seconds than they did covering the same distance without stopping. This apparently has something to do with the sheer inefficiency of stop-start activity. We found that when starting from rest, a significant amount of oxygen is consumed to start walking," said the study's author, Francesco Luciano. We incur this cost regardless of whether we then walk for 10 or 30 seconds, so it proportionally weighs more for shorter rather than longer bouts." Would this strategy, I wondered, work for me?

Chronic fatigue syndrome is as physiological as a broken leg. For the sake of those who have it, we must learn all we can from this tragic caseHow could this happen in the 21st century? This question could apply to many issues, but this one sends you reeling. A brilliant and lively young woman with a common illness was repeatedly disbelieved, dismissed and given inappropriate treatment, until she starved to death. It is a terrible result of the most remarkable situation I've ever encountered in either medicine or journalism.Last week, the coroner at the inquest into the death of Maeve Boothby O'Neill published her damning report on the prevention of future deaths. Maeve was suffering from myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), a condition afflicting hundreds of thousands in the UK. ME/CFS robs those who have it of energy. Severe cases can shut down every aspect of their lives. Continue reading...

Once thought extinct after the fall of empire, this debunked practice has re-emerged with support from rogue experts and rich backersCivilisation is going to pieces ... if we don't look out the white race will be - will be utterly submerged. It's all scientific stuff; it's been proved." Sentiments like this will be familiar to those who lurk in the less wholesome corners of the internet, where racism and other bigotries flourish. As a geneticist who specialises in racism and eugenics, I lurk so that you don't have to.However, this particular phantom threat comes from Tom Buchanan, Daisy's brutish husband, barking these unsolicited words at supper in the opening pages of The Great Gatsby. F Scott Fitzgerald paints a picture of upper-class ghouls that is fundamentally accurate: eugenics, race and the menace of immigrants were defining campaigning issues in Jazz-era America, as they were in Edwardian Britain.Dr Adam Rutherford is a lecturer in genetics at UCL and the author of How to Argue With a RacistThis article was updated on 18 October 2024 to add details of partners participating in a recent Guardian investigation into a race science" network.

An artful account of a scientific genius and her female disciples leaves Marie Curie's inner life an enigmaTo write a biography of a figure as well known as Marie Curie and still offer something fresh or surprising is no easy undertaking. The double Nobel prizewinner is, as author Dava Sobel acknowledges, the only female scientist most people can name. She has inspired more biopics and biographies than I can count, including those written by her two daughters. Parents of young children will have encountered her story in almost every one of the worthy children's anthologies that adorn school bookshelves: she features in Goodnight Stories for Rebel Girls, She Persisted Around the World and Little People, Big Dreams.To help shed new light on such an iconic figure, Sobel, a bestselling writer of science histories, has interwoven her account of Curie's life and scientific discoveries with those of dozens of female scientists who passed through her lab in Paris.

Researchers say people who sit or stand for long periods should schedule regular movements throughout the dayThey have been billed as the ultimate antidote to sitting in front of a screen all day at the office. But a study suggests standing desks, which have soared in popularity in recent years, do not compensate for being inactive and may even increase the risk of conditions such as swollen veins and blood clots in the legs.Research involving more than 80,000 adults in the UK has also discovered that standing does not reduce the risk of diseases such as stroke and heart failure, despite the widely held belief that it does.

Ordaining women | Zeno's walking paradox | Mating mallards | Billionaires' boats | Google goes nuclear | Not in for a pennyConcerning your editorial (The Guardian view on women in the Catholic church: let down yet again, 13 October), it may be worth pondering that the great defender of Catholicism, Thomas More, included in his Utopia (1516) the following description: Male priests are allowed to marry - for there's nothing to stop a woman from becoming a priest, although women aren't often chosen for the job, and only elderly widows are eligible."

Clues in painting suggest Francis Williams successfully managed to compute and witness trajectory of Halley's comet over Jamaica in 1759It was painted to celebrate the groundbreaking achievements of a mathematical genius who was Black and had been born into slavery. But for more than 260 years, that great scientific intellect of Francis Williams went unnoticed.Now, clues exposed by an X-ray and high-resolution scans of the painting have finally revealed the extraordinary secret that 18th-century advocates of slavery sought to keep hidden.

Google's new tool NotebookLM lets you create podcasts at the click of the button. They're way more realistic than you'd think ...Anyone who grew up watching The Terminator or The Matrix knows that AI poses an existential threat to humanity. As the robots become smarter, it was thought, they will inevitably replace us, either by destroying us or mining us for resources. However, the age of AI is now here, and the truth is so much worse than anything from a dystopian sci-fi. You see, AI has decided to give us more podcasts.The world needs more podcasts like it needs to be kicked by a horse. Everyone's got a podcast. Gyles Brandreth has a podcast. Paul Giamatti has a podcast. Your four or five worst friends all have podcasts, blathering endlessly into an environment already cluttered with too much content. Now Google has just created the first AI podcasts, and they're as fascinating as they are superfluous. Continue reading...

CSIRO scientists have mapped the first full genome of the spotted handfish, a step which could aid monitoring, captive breeding and conservation efforts of the critically endangered species. Fewer than 2,000 spotted handfish remain in the wild. Dr Tom Walsh, co-lead of CSIRO's applied genomics initiative, said the genome can provide a better understanding of the species. "What we don't want is for all our endangered species to only exist as genomes," he said. The conservation has to happen on the ground. What the genome can do is provide more information to those people making those decisions." Continue reading...

Forget blue zones, superfoods and hi-tech rejuvenation therapies: study after study suggests our dreams of immortality will never come true. But maybe that's just the kick in the pants humanity needsThe news hasn't been good for people planning to live for ever. First came Dr Saul Newman's investigative work into supercententarians - those aged 110 or older. In a paper titled Supercentenarian and remarkable age records exhibit patterns indicative of clerical errors and pension fraud", Newman reported that high concentrations of supposedly extremely old people occurred, implausibly, in places with the highest rates of poverty- apredictor of the worst health - and with no birth certificates. IntheUS, the number of supercentenarians declined by between 69% and 82%, depending on the state, when birth certificates were introduced.Guttingly for anyone who spends a fortune on jasmine tea and natt by following the Okinawa diet, Newman's research also challenged the notion of blue zones", pointing to high error and fraud rates in those mythic, much-admired areas with high concentrations of centenarians. In 2010, more than 230,000 Japanese centenarians turned out to be missing, imaginary, clerical errors or dead; in Greece, 72% of census-reported centenarians in 2012 were discovered to be dead (or, depending on your perspective, committing pension fraud").

Do certain friends' leave you feeling drained and demotivated every time you meet? You need to have a word with them - and yourselfEllie used to wonder why she always felt drained after spending time with her friends. Then she noticed that they were constantly complaining about their jobs or their partners without ever taking steps to change. Or else they would select an unsuspecting victim and sink their teeth into them. They didn't want to hear about Ellie, 35 - the changes she was making in her life, the new business she had started. And they certainly didn't want to hear that it was going well, she says. You almost felt like you couldn't fit in with them unless you were moaning about something."Maybe you have one of these characters in your life: an old schoolfriend, perhaps, who consistently leaves you feeling worse than before you met up with them. In psychological shorthand, they are known as emotional vampires", for their ability to suck the pleasure from a social interaction - and your energy along with it. But what are the signs that you are in one's clutches, or that you have become one yourself? And how can we best handle suchrelationships? Continue reading...

While healthy eating and regular workouts are certainly good for us, many scientists now believe that genes rather than lifestyle are the determining factor in how long we liveTech entrepreneur Bryan Johnson is talking about 16th-century sailors. Back then, he says, circumnavigating the globe was the height of human achievement. But those sailors, some of whom were coincidentally hoping to find a mythical fountain of youth, left port without knowing what really lay ahead. The same is true for Johnson, 47, who sees himself as a modern-day explorer. Like those sailors, he too is pushing the bounds of what is humanly attainable. Not by circumnavigating the globe, but by circumventing death.Johnson's odyssey involves ingesting 111 pills a day, eating his last (vegan) meal of the day at 11am, staying teetotal, doing an hour of exercise daily and going to bed at 8.30pm. But is it scientifically possible to slow our ageing like this? Or is his plan more likely to end up shipwrecked by reality? Continue reading...
