Research busts myth childcare rejuvenates grandparents – but suggests looking after a neighbour’s child mightGrandparents planning hefty amounts of childcare this half-term might want to think again after research claimed to disprove previous findings of a “rejuvenating effect” from looking after grandchildren.Many studies have appeared to show mental and physical health advantages for those who care for their grandchildren. But none involved researchers talking to the same grandparents before and after their caregiving responsibilities began. Continue reading...

To know the story of this dark science is to inoculate ourselves against its being repeated, argues the science writer and broadcasterThis is a short book about a big subject, with a thorny history stretching from the Spartans and Plato’s Republic, all the way to present-day science and policymaking. A glance at the index gives some idea of its scope. Ancient Greece rubs shoulders with Avengers: Infinity War and the “Do Not Resuscitate” notices of the Covid-19 pandemic with the doctors’ trial at Nuremberg.It takes patience to trace the complicated web linking these ideas, and Rutherford does so with much-needed nuance and an absence of alarmism. “For just over a century, we have referred to the deliberate crafting of society specifically by biological design with a word which was for half of its existence regarded as desirable, and for the other half, poisonous,” he writes. As a geneticist and author of books such as How to Argue with a Racist, Rutherford aims to distil a rounded, scientific analysis from the deeply tainted and overheated subject of eugenics.

A few weeks ago, Elon Musk’s company Neuralink posted a job advert recruiting for a ‘clinical trial director’ to run tests of their brain-computer interface technology in humans. Neuralink’s initial aim is to implant chips in the brain that would allow people with severe spinal cord injuries to walk again. But, Musk himself has said that he believes this technology could one day be used to digitally store and replay memories.Madeleine Finlay speaks to Prof Andrew Jackson about how brain-computer interfaces actually work, where the technology is at the moment, and if in the future we could all end up communicating telepathicallyArchive: Today, Fox 35 Orlando, Space X, Wall Street Journal, CNET, Neuralink Continue reading...

Keytruda treatment found to cut risk of aggressive cancer returning after surgery by more than a thirdThousands of lives could be saved with a “promising” immunotherapy drug that can cut the risk of an aggressive form of breast cancer returning by more than a third, according to “exciting” results from a long-term global study.Keytruda, also known as pembrolizumab, uses the patient’s own immune system to fight cancer. The drug works by helping the immune system recognise and attack cancer cells, and is already used to treat lung cancer, skin cancer, bladder cancer and Hodgkin lymphoma. It is administered in a solution via a drip into the patient’s bloodstream, with the number of sessions depending on the type of cancer. Continue reading...
Researchers find Homo sapiens moved into Madrin cave in France one year after Neanderthals abandoned itHomo sapiens ventured into Neanderthal territory in Europe much earlier than previously thought, according to a new archaeological study.Up to now, archaeological discoveries had indicated that Neanderthals disappeared from the European continent about 40,000 years ago, shortly after the arrival of their “cousin” Homo sapiens, barely 5,000 years earlier and there was no evidence of an encounter between these two groups.

Covid has made it clear: the likes of Pfizer, in thrall to shareholders, only really care about their huge profitsPfizer has had an exceptionally good pandemic. Today it announced that its Covid-19 vaccine brought in $37bn billion last year, making it easily the most lucrative medicine in any given year in history.That isn’t all. For a company that was until recently the least trusted company in the least trusted industrial sector in the United States, Covid-19 has been a PR coup. Pfizer has become a household name over the last 12 months. The company was toasted on nights out in Tel Aviv, and there are cocktails named after its vaccine in bars across the world. The US president referred to Pfizer’s chief executive, Albert Bourla, as a “good friend”, and the great man parked his jet next to Boris Johnson’s at last year’s G7 summit in Cornwall.Nick Dearden is director of Global Justice Now Continue reading...

Research suggests electric shocks could be key to growing raindropsAn electric shock might be just the thing to persuade a cloud to produce some rain. New research suggests that supercharging a cloud could increase the attractive forces between droplets and help raindrops to grow. Have we finally found the recipe for making rain?Electric charge is all around us. Thunderclouds literally crackle with it, but even the air we breathe has some charged aerosols and droplets in it. Giles Harrison, a meteorologist at the University of Reading, and colleagues have been investigating the electric charge of drops in non-thunderstorm clouds. Continue reading...

Late in November, the World Health Organization designated the Covid variant B.1.1.529, with its many mutations, as a variant of concern. Dubbed Omicron, within weeks it had rapidly spread across the globe and become the dominant variant. But not far behind has been its even more transmissible cousin, BA.2. Initially taking off in Denmark and India, BA.2 is now making headway in several countries around the world, including the US and UK.Ian Sample speaks to Prof Nick Loman about how worried we should be about BA.2, and what we still need to learn about this new subvariantArchive: DW News, WION Continue reading...

An exhibition of vivid photographs and a restored documentary give fresh insight into the Antarctic explorer, who died a century agoOne hundred years ago, the leader of the last great expedition of the heroic age of polar exploration died from a heart attack as his ship, Quest, headed for Antarctica. The announcement of the death of Ernest Shackleton on 30 January 1922 was greeted with an outpouring of national grief.This was the man, after all, who had saved the entire crew of his ship Endurance – which had been crushed and sunk by ice in 1915 – by making a daring trip in a tiny open boat over 750 miles of polar sea to raise the alarm at a whaling station in South Georgia.

Changing minds is more complicated than simply exposing poor argumentsHow do you react when someone politely but firmly tells you that you’re talking nonsense about something that’s important to you? Do you gracefully and immediately give way to their greater expertise? Or do you double down?Most of us are in the latter camp. Voicing our beliefs tends to solidify them. We may like to think of ourselves as rational creatures, constantly assessing the world for new information that might change our minds, but this is not how our brains work. Explaining to someone that their belief is flat-out wrong is not a good way of getting them to drop it. And research shows that the process of “myth-busting” – setting out a common false statement, then explaining why it is wrong – backfires because it counterintuitively reinforces and helps spread the myths.

A successful pregnancy for Elizabeth Ann may help ensure her species avoids extinctionElizabeth Ann is poised to make history. The world’s first cloned black-footed ferret has just celebrated her first birthday and has reached an age when she can start to breed. And, if she is successful and produces healthy kits, the little predator will give a precious boost to attempts to save her seriously endangered species.However, scientists acknowledge that they will have to be extremely careful in screening possible mates for Elizabeth Ann, who is being kept at a conservation centre near Fort Collins, Colorado. In particular, the male they eventually select will have to display one key quality, they say: he will have to be gentle. Continue reading...
The consultant neurologist and BBC radio presenter has a new book exploring the relationship between sensory perception and the reality it createsGuy Leschziner is a consultant neurologist at Guy’s and St Thomas’ hospitals. His areas of expertise are epilepsy and sleep disorders. He has presented two BBC radio series, one on sleep and another on the neurology of our sensory world. His latest book is The Man Who Tasted Words, which explores the relationship between our sensory perception and the reality it constructs.A common phrase in cognitive neuroscience is “perception is nothing more than controlled hallucination”. What exactly does that mean?
Nudged along by scientists and evolution, micro-organisms that digest plastics have the potential to create an efficient method of recyclingBeaches littered with plastic bottles and wrappers. Marine turtles, their stomachs filled with fragments of plastic. Plastic fishing nets dumped at sea where they can throttle unsuspecting animals. And far out in the Pacific Ocean, an expanse of water more than twice the size of France littered with plastic waste weighing at least 79,000 tonnes.The plastic pollution problem is distressingly familiar, but many organisations are working to reduce it. Alongside familiar solutions such as recycling, a surprising ally has emerged: micro-organisms. A handful of microbes have evolved the ability to “eat” certain plastics, breaking them down into their component molecules. These tiny organisms could soon play a key role in reducing plastic waste and building a greener economy. Continue reading...
Megan Nolan always dreamed of having her own lovely home. But now terrifying thoughts keep her awake at night. Here, the author wonders whyI live by myself in a good place, the best sort of place a woman like me could imagine. In fact, it’s all I did imagine for years on end. I rent rather than own it, but that’s no hardship. I’ve never felt any particular angst to own property, which is just as well since I live in London, a place where I could no sooner get a mortgage than a giraffe. Owning a home has always felt more like a burden, like an end to things, to me, than it has felt like comfort. I did always dream, though, of renting somewhere beautiful and living alone there – and now I do.On the days I spend here without anyone else, I wake up at 8.30 and feed my cat. I watch her eat her disgusting, stinky food with satisfaction, glad I’m able to keep another creature beyond myself alive. I make coffee and wander about the flat a bit, wiping surfaces, washing tomato-laden pots. I go for a walk or to the gym, and then I work. I write. I send emails. I complain or speculate about everything I’m doing constantly to my friends. For lunch I blitz the vegetables in the fridge into a soup, or else walk down the road to the pub for a sandwich, and come back and work some more. I gaze adoringly at the cat. It becomes evening and I might drink a glass of wine, sometimes a bottle. I cook dinner and eat it in 13 minutes while watching MasterChef. I read for an hour. I work a bit more. Sometimes I watch a film. This is the life I have designed for myself, the life I never thought I would be so lucky as to have. Then it is time to sleep. Continue reading...
The GSK executive has found her niche at ViiV Healthcare developing HIV drugs, and is optimistic a cure will be foundA lot has changed since the devastating 1980s Aids crisis depicted in the Channel 4 TV show It’s a Sin – but the stigma attached to the illness remains, says Deborah Waterhouse. As chief executive of ViiV Healthcare, a GlaxoSmithKline-controlled joint venture that develops HIV drugs, she leads one of the largest commercial developers of Aids treatments in the world.“I remember in 1987 GSK brought the first medicine out for HIV and at that point the life expectancy for someone living with HIV was 18 months,” she tells the Observer, speaking via video link from her study lined with novels, travel and music books in her home in Richmond, west London.
