The Big Idea: how do our brains know what’s real?
From seeing things to hearing voices, there's a finer line between hallucination and reality than you might supposeWhen did you last hallucinate? The visionary tendency is much more common among sane people than is generally suspected," wrote the 19th-century psychologist Sir Francis Galton. Setting aside the vivid, often emotive, cinema of our dreams, we are all more vulnerable to seeing things" than we might at first suppose.Around four fifths of people who have recently been bereaved report an encounter with their loved one: most commonly a lively sense of their presence, but some hear, see or speak with them. Up to 60% of people who lose sight in later life see things that aren't there, sometimes extravagant images such as the two young men ... wearing magnificent cloaks ... their hats ... trimmed with silver" who appeared in the first reported case of Charles Bonnet syndrome, as this phenomenon is known, before dissolving" away. A 20-year-old woman blindfolded for 12 hours saw cities, skies, kaleidoscopes, lions and sunsets so bright she could barely look at them'". After losing a limb, most people carry a constant or inconstant phantom of the missing member", as Weir Mitchell, the American neurologist who coined the term phantom limb after studying 90 cases from the American civil war, put it. Pilots on long flights, travellers through snowstorms and deserts, prisoners and hostages held in darkness; their restless brains are all prone to see the things of which they're being deprived.

Starwatch: look out for Venus blazing brightly in inconspicuous Pisces
The evening star will serve as a handy signpost for identifying the often unnoticed constellationHaving reached its highest point in the evening sky last week Venus is beginning to move back towards the sun. But before it disappears from view in March, it will continue to put on a dazzling show.It will blaze brightly on 16 February at a magnitude of -4.2, the brightest of this apparition. It will also still be high enough in the sky to be well visible several hours after the sun has set, when the sky is fully dark. Continue reading...

When my daughter’s pregnancy was on the line, it felt like history was repeating itself…
Joanna Moorhead recalls her daughter's difficult birth as she watches her go through the same thing 32 years laterIt was a routine antenatal appointment with many weeks still to go until the birth. Things aren't quite as we'd hope," said the midwife, a worried look on her face. You need to go straight to hospital."The date was 8 April 1992. But also, it was 1 August 2024. The bump in 1992 was mine; the baby, who would be born the following day, at 29 weeks' gestation (term" is 40 weeks) was my daughter Rosie. The bump in 2024 was hers: 32 years on, history was repeating itself. Continue reading...

Anti-ageing jabs – they can rejuvenate mice, but will they work on humans?
Senescent cells power the body's ageing process, and scientists are developing treatments to annihilate themAt St Jude children's research hospital in Memphis, Tennessee, an unusual clinical trial is under way that, if successful, could have wider ramifications for the vast field of age-related chronic diseases. At first glance, childhood cancer survivors may seem like an unusual population in which to study ageing, but as Greg Armstrong, principal investigator of St Jude's Childhood Cancer Survivorship Study, explains, we now know they represent a group of individuals who are ageing unusually quickly.For while modern chemotherapies and radiotherapies have become increasingly efficient at curing childhood cancers, this comes at a great cost, owing to the corrosive impact of such treatment on these children's bodies, something that becomes more apparent when they reach middle age.

Elon Musk put a chip in this paralysed man’s brain. Now he can move things with his mind. Should we be amazed - or terrified?
An accident left Noland Arbaugh paralysed, but Musk's Neuralink brain implant allows him to control computers with his thoughts. Is it a life-changing innovation that could help millions - or the start of a dystopia where a billionaire can access our thoughts?Noland Arbaugh's life changed in a fraction of a second in June 2016. He was a 22-year-old student, working at a kids' summer camp in upstate New York, when he went swimming in a lake. He can't tell me exactly what happened, but thinks one of his friends must have accidentally struck him very hard in the side of his head as they ran into the water and plunged beneath the surface.When he woke up face down in the water, unable to move or breathe, Noland immediately knew he was paralysed. But he didn't panic. He felt no fear at all, he says. You never know what you're going to do in those high-stress situations. I found out that day that it's hard to shake me. I am very, very calm under pressure." Continue reading...

We need to keep an open mind on cold fusion potential | Letters
Scientists around the world are leading research into cold fusion as an alternative to fossil fuels so it should not be dismissed as pseudo-scientific, say MIT-based researchers. Plus a letter from Huw PriceRecently, the letters pages of the Guardian have featured conflicting accounts of cold fusion, otherwise known as low-energy nuclear reactions (LENR). On the one hand, the Nobel laureate Prof Brian Josephson and his co-authors argue (27 January) that cold fusion's time has come: companies can make these reactions work quite reliably", with the promise of ending reliance on fossil fuels". In response, Dr Philip Thomas, a researcher at the University of Exeter, proclaims (2 February) that cold fusion is a pseudo-scientific fringe theory" in violation of the laws of nature". Which laws, in particular, Dr Thomas does not say.There is, however, a constructive middle ground between Josephson's fervour and Thomas's denigration. LENR advocates often fail to appreciate the evidentiary standard required to demonstrate novel nuclear effects. Overzealous critics are generally not well read on the LENR literature and lack perspective on the emergence of new fields from anomalous effects in science. As a result, they contribute to the palpable stigma that the Cambridge emeritus professor Huw Price calls the reputation trap". Regardless, there is compelling experimental data and strong theoretical motivations to study cold fusion. Continue reading...
Mystery behind Viking-age treasure find in Scotland may finally have been solved
A runic inscription on one of the Galloway hoard's elaborately decorated arm rings has been decipheredWhen the Galloway hoard was discovered in a ploughed field in western Scotland in 2014, it proved to be the richest collection of Viking-age objects ever found in Britain or Ireland. Now the long-standing mystery of who might have owned it when it was buried more than 1,000 years ago may have been solved.The spectacular silver and gold treasure had in fact belonged to everybody - the community" - just as it does today, having been acquired in 2017 by National Museums Scotland (NMS).

Scientists crack what they say is the perfect way to boil an egg
Linda Geddes tests new approach developed in Italian lab that involves alternating egg between different temperaturesDelia Smith demands one minute of simmering plus six of standing with the pan lid on. Heston Blumenthal brings his to the boil from cold. Now scientists have weighed in on the perfect way to boil an egg, and the results are egg-stremely tasty.From a materials perspective, cooking an egg within its shell is more complicated than it might at first seem. Chefs are challenged by the fact that an egg's components: yolk and white, are made of different proteins that denature and thicken at different temperatures: 85C (185F) for the white and 65C (149F) for the yolk.

It came from outer space: the meterorite that landed in a Cotswolds cul-de-sac
Meteorite falls are extremely rare and offer a glimpse of the processes that formed our world billions of years ago. When a space rock came to an English market town in 2021, scientists raced to find as much out as they couldAt 21.54 on 28 February 2021, 16 cameras belonging to amateur sky-watching network UKMON picked up a bright shape headed towards Earth. Pictures show a long white line, which was visible for eight seconds, a glowing globule of light against the dark sky. For me it's like fishing," said Richard Kacerek, one of the founders of UKMON. You cast your line and then you wait. There are days when you catch nothing but there are days when you catch a really, really big fish and it's so exciting." The fireball of February 2021 was such a fish: a lump of flaming extraterrestrial rock travelling at a speed of about 8.4 miles a second - 15 times the speed of a rifle bullet - and headed for the Cotswolds market town of Winchcombe.Meteorites are rocks from space that have entered our atmosphere. Most were once part of asteroids - the rocky, airless remnants left over from the formation of our solar system 4.6bn years ago. Almost all of them are what collectors call finds", meaning that the stone has been discovered by searching the ground, having fallen earlier - in most cases several thousand years earlier. A fall", a meteorite that is seen in flight and then recovered, is very, very rare. Worldwide, typically only about 10 such rocks are picked up each year. Before 2021, the last reported UK fall was a rock the size of a cricket ball that landed in a hedge in Glatton in Cambridgeshire in May 1991. Continue reading...

Cold fusion claims that don’t bear scrutiny | Letters
Dr Philip Thomas responds to a letter claiming that cold fusion could be a viable alternative to fossil fuelsI was disappointed to see a letter promoting a pseudo-scientific fringe theory (Cold fusion may be a viable energy alternative to end reliance on fossil fuels, Letters, 28 January). Many scientists have tried and failed to reproduce Martin Fleischmann and Stanley Pons's initial report of cold fusion. After years of intense scrutiny, the mainstream scientific community overwhelmingly concluded by the early 1990s that cold fusion was not a credible idea supported by experimental evidence - a conclusion that stands after three decades of research.The authors of the letter to the Guardian suggest that cold fusion research is now being suppressed from publication. In reality, credible, rigorous studies continue to be published in reputable journals (such as a 2019 study in Nature), but none of them has successfully observed cold fusion. The letter claims that companies have been able to make these reactions work quite reliably", but do not provide any evidence to support this. Continue reading...

‘Female narcissism is often misdiagnosed’: how science is finding women can have a dark streak too
Research into dark personality traits' has always focused on men. But some experts believe standard testing misses the ways an antisocial personality manifests itself in womenPicture a psychopath. Who do you see in your mind's eye? Chances are it's a man. And chances are your answer would be similar if you were asked to picture a narcissist. From Charles Manson and Ted Bundy to Joseph Stalin, Adolf Hitler and Donald Trump, most famous people we consider psychopathic or narcissistic are male. That's even the case for fiction - think Hannibal Lecter, Patrick Bateman or Norman Bates.Scientists long assumed that women were simply too wonderful to be significantly psychopathic or narcissistic, and didn't bother to study the possibility much, according to Ava Green from City St George's, University of London. But research over the past few decades is increasingly challenging this stereotype, suggesting women can have a dark streak, too. Much like in autism or ADHD, such traits just express themselves slightly differently in women - making them harder to spot with diagnostic tests that were essentially developed for men.

UK scientist wins prize for invention that could help avert ‘phosphogeddon’
Phosphate, key to food production, is choking waterways, but a new sponge-like material returns it to the soil for cropsIt is one of the least appreciated substances on the planet and its misuse is now threatening to unleash environmental mayhem. Phosphorus is a key component of fertilisers that have become vital in providing food for the world. But at the same time, the spread of these phosphorus compounds - known as phosphates - into rivers, lakes and streams is spreading algal blooms that are killing fish stocks and marine life on a huge scale.It is a striking mismatch that is now being tackled by a project of remarkable simplicity. The company Rookwood Operations, based in Wells, Somerset, has launched a product that enables phosphates to be extracted from problem areas and then reused on farmland. Continue reading...
