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...

British scientists have developed simple ways for those in danger areas to make complex medical equipment quicklyTwo shattering events played a critical role in British scientists' efforts to develop technology that could transform the treatment of people who suffer traumatic injuries in wars or disasters.The first was the blast that devastated Beirut on 4 August 2020, when a vast store of ammonium nitrate exploded in the city, killing more than 200 people and injuring 7,000. The second was Russia's invasion of Ukraine, which has left hundreds of thousands of casualties have been inflicted since war erupted there in February 2022. Continue reading...

The US scientist on being the first Black woman to descend to Earth's deepest point, ignoring career advice - and what really happened to the Titan submersibleThe American oceanographer Dawn Wright is the first Black person and only the 27th human to have been to the deepest spot on the planet. Challenger Deep, at the southern end of the Mariana Trench in the western Pacific Ocean, is 10.9km (6.8 miles) below sea level - deeper than Mount Everest (8.8km [5.5 miles]) is tall. Wright's summer 2022 descent is documented in a new book, Mapping the Deep, written with her input. The dive was undertaken in a two-person submersible called Limiting Factor owned (since sold) by Caladan Oceanic, an ocean expedition company founded by investor turned deep sea explorer Victor Vescovo, who was also the craft's pilot. Wright, 63, who also goes by the moniker Deepsea Dawn", is the chief scientist of Esri, a multinational that makes geographic information system (GIS) software for mapping and spatial analytics.Sending people to the deep ocean can be dangerous because of the extreme underwater pressure. Last year, OceanGate's Titan submersible imploded on a journey to view the wreck of the Titanic, killing all five passengers on board. Why not just leave it to robots?
