The secrets of highly persuasive people, from a hostage negotiator to a TV producerSome people are just charmers. They can sweet-talk an otherwise immovable doorman, cajole asmall child into picking uptheir toys without protest, and smile their way to a freebie. But being ablagger isn't the preserve of aselect few loudmouths and self-aggrandising entrepreneurs; highly persuasive people walk among us. Iknow, Imarried one.Lost the receipt? No matter; my nice, softly spokenhusband somehow gets the item returned. Acomplimentary upgrade to business class? It has been known. He's particularly astute atgetting let off the hook - having a missed appointment fee waived, say. There was even the incident where he smashed a bus window (an accident, he maintains) and the bus company sent him a letter to apologise. Continue reading...

Taylor Swift is just one of countless victims of deepfake videos. Firms feeding off this abuse should pay for the harm they causeImagine finding that someone has taken a picture of you from the internet and superimposed it on a sexually explicit image available online. Or that a video appears showing you having sex with someone you have never met.Imagine worrying that your children, partner, parents or colleagues might see this and believe it is really you. And that your frantic attempts to take it off social media keep failing, and the fake you" keeps reappearing and multiplying. Imagine realising that these images could remain online for ever and discovering that no laws exist to prosecute the people who created it. Continue reading...

Writer and dementia campaigner who believed that people should have the right to choose their own deathThe writer-activist Wendy Mitchell, who has died aged 68, won hearts and minds by advocating for living positively with dementia. She was determined to remind people that those living with the disease are not sufferers" and that there is a beginning, a middle and an end to the disease - with so much life to be lived in between". She held strong beliefs that people should have the right to choose their own death, and campaigned for assisted dying laws in Britain - one of the subjects of her final book.Wendy wrote three bestsellers, Somebody I Used to Know (2018), What I Wish People Knew About Dementia (2022) and One Last Thing: How to Live with the End in Mind (2023) - I was fortunate enough to be her ghostwriter on all of them.

People with aphantasia can't mentally visualize things. Mental imagery is a spectrum, and we lie outside it, in the darkI discovered I had aphantasia by accident. When you live your entire life without a mind's eye", it seems completely normal to visualize nothing when remembering people and places, or imagining the future.Two years ago, I wrote an article about pupillometry, or the measurement of a person's pupils to infer their cognitive state. Joel Pearson, a psychologist and neuroscientist at the University of New South Wales, was trying to use pupils as a biomarker to assess aphantasia, a condition thought to affect about 3.9% of people.

Blue giant in Virgo constellation pumps out almost 21,000 times the light of the sunOnce again the moon is our guide this week, passing within about 1.5 of Spica, the brightest star in Virgo, the virgin. The full circle of the moon presents an angular diameter of about 0.5, so it will approach Spica to about six lunar widths.The chart shows the view looking south-east from London at 23.00 GMT on 28 February, shortly after the pair have risen. Having passed full moon, the waning moon will now rise later and later, with less and less of its visible surface illuminated. On 28 February, 83% of its Earth-facing hemisphere will be illuminated. By next week, it will be a thin crescent rising in the morning sky before the sun. Continue reading...

The spectre of the mob' has long been summoned to limit freedom. There's just one problem: protests almost never lead to violenceA spectre is haunting Westminster - the spectre of collective violence against MPs. Large crowds chant noisily outside parliament during debates on Palestine; protesters surround Tobias Ellwood's house; Jo Stevens' constituency office is vandalised - and all this against the backdrop of the murders of David Amess and Jo Cox. The parties are united in seeking to exorcise this spectre. It has already led to parliamentary procedure being changed in a way that made a mockery of the debate over violence in Gaza. It has also led to calls for new police powers to curb protests outside parliament. But is collective violence the problem here, and is the introduction of yet more curbs on protest the answer?Certainly, acts of vandalism and of violence against MPs cast a chill over our democracy and have no justification. But over the past months, a few individual acts have become conflated with the collective protests - and in turn, protest has been equated with violence, or the threat of it.Stephen Reicher is a professor of psychology at the University of St Andrews and a fellow of the Royal Society of Edinburgh and the British AcademyDo you have an opinion on the issues raised in this article?

Lab-grown meat could become a mainstay in restaurants if products win regulatory approval. Biologists and chefs share menu ideasWhether roasted, grilled, fried or stewed, the combination of fat, umami and texture in a premium cut of meat is difficult to recreate. With sales of plant-based meat stagnating, the hunt for cruelty-free, sustainable and meaty-tasting alternatives continues. Enter lab-grown meat. Fermented in tanks, using cells from long-dead donors, it promises a more climate- and animal-friendly form of meat for the carnivore with a conscience.Last week, researchers announced that they had created beef-cultured rice", which, while not exactly replicating the taste of a pan-fried steak, offers a pleasant and novel flavour experience" that could improve emergency food supplies or provide rations for astronauts and the military. At the opposite end of the spectrum, gourmet restaurants in the US and Singapore are already serving up cultured chicken to adventurous diners, while regulators in Singapore, Switzerland and Israel are considering whether to approve further products.

Studies suggest the BCG jab discovered a century ago could provide a cheap and effective way of boosting the immune system to protect people from developing the conditionScientific discoveries can emerge from the strangest places. In early 1900s France, the doctor Albert Calmette and the veterinarian Camille Guerin aimed to discover how bovine tuberculosis was transmitted. To do so, they first had to find a way of cultivating the bacteria. Sliced potatoes - cooked with ox bile and glycerine - proved to be the perfect medium.As the bacteria grew, however, Calmette and Guerin were surprised to find that each generation lost some of its virulence. Animals infected with the microbe (grown through many generations of their culture) no longer became sick but were protected from wild TB. In 1921, the pair tested this potential vaccine on their first human patient - a baby whose mother had just died of the disease. It worked, and the result was the Bacille Calmette-Guerin (BCG) vaccine that has saved millions of lives. Continue reading...

Some projects to save species just don't work. Now, a Cambridge University team is amassing hard scientific evidence of best practiceIt seemed like a good idea at the time: build metal bridges over busy roads and bats would confuse them with trees, it was argued. They would then try to soar over the pylons and, having been tricked into flying higher than normal, would avoid being struck by lorries and buses travelling on the road below. A widespread wildlife problem for the UK would be solved at a stroke.It was a persuasive vision, and to realise it, a total of 2m was spent on building 15 bat bridges across Britain, from Cumbria to Cornwall. However, there was one problem," said Professor William Sutherland of the Conservation Science Group at Cambridge University. The bridges didn't work." Continue reading...

The footage put together by Sora looks swish, but closer examination reveals its doesn't understand physical realityFirst text, then images, now OpenAI has a model for generating videos," screamed Mashable the other day. The makers of ChatGPT and Dall-E had just announced Sora, a text-to-video diffusion model. Cue excited commentary all over the web about what will doubtless become known as T2V, covering the usual spectrum - from Does this mark the end of [insert threatened activity here]?" to meh" and everything in between.Sora (the name is Japanese for sky") is not the first T2V tool, but it looks more sophisticated than earlier efforts like Meta's Make-a-Video AI. It can turn a brief text description into a detailed, high-definition film clip up to a minute long. For example, the prompt A cat waking up its sleeping owner, demanding breakfast. The owner tries to ignore the cat, but the cat tries new tactics, and finally, the owner pulls out his secret stash of treats from underneath the pillow to hold off the cat a little longer," produces a slick video clip that would go viral on any social network.

Proposal focuses on technique that fills atmosphere with particles, reflecting part of sun's heat and light back into spaceSwitzerland has initiated a global debate on whether the risks, benefits and uncertainties" of dimming the sun should be studied by a United Nations expert group.It is proposing that the world body should gather information about ongoing research into solar geoengineering, and set up an advisory panel that could suggest future options for the untested and controversial approach to reduce global heating, which would have implications for food supply, biodiversity, global inequality and security.This article was corrected on 22 February 2024. A previous version stated that 400 scientists had signed the appeal for a solar geoengineering non-use agreement, and also said that opponents of SRM had contributed to the One Atmosphere report. A further correction on 23 February 2024 clarified details around the research funding. Continue reading...

Arguments about sex differences in the brain have raged for centuries. As intriguing as they are, surely there are more urgent questionsThere seems to be an insatiable public appetite for information about sex differences in the human brain, eagerly harnessed by the media in many forms. A paper out this week from a research group at Stanford University made headlines for its innovative contribution to this form: using an AI neural network model to look at brain scans to see if it could reliably" and robustly" tell female and male brains apart. In other - more neutral - words, could the algorithm tell whether the brain patterns being looked at were from women or men?The answer was yes", though rather more guarded in the paper itself than in the reports about it. What was interesting about the study was that it seemed to have moved beyond the stereotypical size matters" agenda - asking whether male or female brains are bigger or smaller in different areas - instead measuring differences in the working brain using a method that looked at differences in blood flow to various brain regions.Prof Gina Rippon is emeritus professor of cognitive neuroimaging at the Aston Brain Centre, Aston University, and the author of The Gendered BrainDo you have an opinion on the issues raised in this article?
