Third series of TV drama spiked interest in anti-anxiety drug amid warnings over illicit production of benzos'In the third series of the hit TV show The White Lotus, the entitled North Carolina housewife Victoria Ratliff is often shown reaching for her lorazepam. Now researchers say internet searches for the anti-anxiety drug surged after the show's release.Lorazepam, also known by its brand name Ativan, is a type of drug known as a benzodiazepine, or benzo". It is thought to work by boosting the effect of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain. Continue reading...

Was the wartime chant about his solitary testicle correct? Did he have Jewish ancestry? New documentary Hitler's DNA is trying to answer these, and more contentious, questions - but should it have gone there at all?If a TV programme sets about sequencing the genome of Adolf Hitler - the person in modern history who comes closest to a universally agreed-upon personification of evil - there are at the very least two questions you want the producers to ask themselves. First: is it possible? And second, the Jurassic Park question: just because scientists can, should they?Channel 4's two-part documentary Hitler's DNA: Blueprint of a Dictator is not the first time the self-consciously edgy British broadcaster has gone there. In 2014's Dead Famous DNA, it inadvertently answered both these questions in the negative. Having first cast aside ethical integrity by paying Holocaust denier David Irving 3,000 for a lock of hair purporting to belong to Adolf Hitler, the programme's makers then discovered it not to be Hitler's and thus useless for DNA sequencing.

Blue Origin says it is aiming for another attempt as soon as Wednesday as competition with Musk's SpaceX intensifiesBlue Origin, the space company owned by billionaire Jeff Bezos, was forced on Sunday to postpone the anticipated launch of its New Glenn rocket due to unfavorable weather conditions in Cape Canaveral, Florida.Rain and a ground system issue caused delays that were followed by cumulus cloud cover as the 88-minute launch window closed, leaving managers with the only option of pushing back the rocket's planned second mission. Competition between Blue Origin and Elon Musk's SpaceX has been intensifying in recent months. Continue reading...

Tearing up, sweating and other bodily functions are all signs that the body is trying to expel spicy foods as quickly as possible. But there is a simple reason why some people enjoy those sensationsThe first thing to understand about eating spicy food is that it really isn't a matter of taste. Capsaicin, the active chemical in capsicum plants that are a key ingredient in anything you'd think of as spicy", evolved as an irritant to stop mammals from chewing and destroying plant seeds. It acts on the nervous system directly through receptors in the tongue, throat and skin - no taste buds required - and, in theory, tells our bodies that the thing we've just ingested is something to get rid of as soon as possible. The obvious question, then, is: why do some of us like the sensation so much?To start to understand that, it's helpful to know a bit more about what's going on in the body. Think of an engineering brief where we have to detect irritants in a system and clear them rapidly," says Liam Browne, an associate professor at UCL who specialises in the neuroscience of sensory perception and pain. Capsaicin binds to a receptor in the body called TRPV1, which is found in a specialised class of neurons called nociceptors that usually detect things that are potentially damaging to the body." When that happens, it's like a little fire alarm goes off and activates parts of the autonomic nervous system, which regulates various involuntary bodily functions without conscious control. That's what leads to all these physiological effects like tearing up, sweating, or your nose running," says Browne. It's your body trying to get rid of the irritant." Continue reading...

Fascination of investors such as Elon Musk with uploading their brains to computers is hindering progress in curing disease, say scientistsIt has been an excellent year for neurotech, if you ignore the people funding it. In August, a tiny brain implant successfully decoded the inner speech of paralysis patients. In October, an eye implant restored sight to patients who had lost their vision.It would just be better, say experts, if the most famous investors in the space - tech magnates such as Elon Musk and OpenAI's Sam Altman - were less interested in uploading their brains to computers or merging with AI.

Nobel prize-winning biologist whose discovery, with Francis Crick, of the structure of DNA solved the mystery of genetic inheritanceJames Watson, who has died aged 97, had an extraordinary gift for science, combined with ruthless ambition and an arrogant disregard for most of his peers. These combined qualities earned him a key role in one of the 20th century's most profound scientific revolutions, a share in a Nobel prize, a bestselling memoir, a place in science history and the anger of many of his colleagues.With Francis Crick, at Cambridge University in 1953, Watson discovered the structure of the giant molecule DNA - deoxyribonucleic acid, found in almost every living cell - and demonstrated that all inheritance, and even life itself, could be explained by chemistry and physics. The discovery revealed new horizons in evolutionary, biological, medical, archaeological, conservation and criminal sciences, and launched an industrial revolution, all within the working lifetime of the discoverers.

Robert Beattie, 82, has found specimens of a 151m-year-old midge that challenge what we know about how the insects evolved

Last weekend's Cambridgeshire train attack brought up a question that we often ask ourselves. But the answer isn't simple

Modern research shows the public work together selflessly in an emergency, motivated by a strong impulse to helpIt was early morning on 1 January last year when Colin McGarva dived into a flooding river in Worcester to rescue an unconscious woman. McGarva said he didn't think twice about the risk to himself, or the devastating loss his newborn son would suffer had he too been swept away by the fast-flowing icy waters.I didn't stop to think because the instinct - the instant reaction - is to help someone in need," he said. Someone's life is an important thing. Helping is just something you have to do." Continue reading...

Nobel prize winner shaped medicine, crimefighting and genealogy, but later years marred by racist remarksJames Dewey Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped light the long fuse on a revolution in medicine, crimefighting, genealogy and ethics, has died, according to his former research lab. He was 97.The breakthrough - made when the brash, Chicago-born Watson was just 24 - turned him into a hallowed figure in the world of science for decades. But near the end of his life, he faced condemnation and professional censure for offensive remarks, including saying Black people were less intelligent than white people. Continue reading...

History tells us that polite incrementalism and political kowtowing will prevail at Cop30 - even as catastrophe unfolds around usAs world leaders gather in Brazil this year for Cop30 - the first Amazonian Cop - it's worth doing a quick reality check on how we are collectively tracking to reduce global greenhouse gas emissions.Despite 30 years of UN climate summits, about half of the carbon dioxide accumulated in the atmosphere since the Industrial Revolution has been emitted since 1990. Incidentally, 1990 was the year the Intergovernmental Panel on Climate Change - the global authority on climate change science - released its First Assessment Report confirming the threat of human-caused global warming. As scientists all over the world prepare the IPCC's Seventh Assessment Report, we do so knowing that our work is still being overshadowed by politics. Despite all the well-intentioned half-measures, the truth is that the world is still disastrously off track to limit dangerous climate change.Dr Joelle Gergis is an award-winning climate scientist and writer from the University of Melbourne. She served as a lead author on the United Nations' Intergovernmental Panel on the Climate Change's Sixth Assessment Report Continue reading...

This hit debut from Finland is intensely readable, but could have delved more deeply into the links between human progress and environmental destructionIn November 1741 Georg Wilhelm Steller, theologian, naturalist, and curious man", was shipwrecked on an island between Alaska and Russia. There he found, floating in the shallow waters, a vast sirenian, Hydrodamalis gigas, nine feet long and soon to be known as Steller's sea cow. Having made it through the winter, largely byeating the sea cows, the following August Steller and the remaining survivors of the Great Northern Expedition left the island. Within 30years, Steller's sea cow was huntedto extinction.Having described these events, Finnish author Iida Turpeinen's debut novel goes on to describe the lives of other historical figures, each of whom are touched in some way by the sea cow, now reduced to bones. There is Hampus Furuhjelm, governor of Alaska, in search of a complete skeleton, and his sister Constance, who finds peace and intellectual autonomy among her taxidermy collection. Later, there's Hilda Olson, a scientific illustrator, andJohn Gronvall, specialist in the reconstruction of birds' eggs, who is tasked with preparing a sea cow's relicsfor exhibition.

Astronomers cast doubt on Nobel prize-winning theory and suggest universe could end in big crunch'Astronomers have cast doubt on a Nobel prize-winning theory that the expansion of the universe is accelerating, suggesting that instead it may be slowing down.If confirmed, this would have profound implications for the fate of the universe, raising the possibility that rather than expanding for ever, the universe could ultimately enter a reverse big bang scenario known as the big crunch. The astronomers behind the work say their observations also imply that dark energy - the mysterious force thought to be propelling the expansion of the universe - is weakening over time.

On 5 November, the moon will be just under 357,000km from Earth, making it appear bigger and brighterThis week brings the largest supermoon of the year. Supermoons occur because the moon's orbit is not perfectly circular around the Earth. Instead, it is an ellipse, meaning that sometimes the moon will be closer to the Earth than at other times.When a full moon coincides with the moon being within 10% of its closest point to Earth, we call it a supermoon. Its proximity makes it appear subtly bigger and brighter than other full moons. Continue reading...
