Bacteria for paratyphoid fever and relapsing fever found in DNA from teeth of troops buried in mass graveWhen Napoleon ordered his army to retreat from Russia in October 1812, disaster ensued. Starving, cold, exhausted and struggling with sickness, an estimated 300,000 soldiers died.Researchers now say they have identified two unexpected diseases among soldiers who died in the retreat - paratyphoid fever and relapsing fever - which provide fresh insights into their plight.

Dating of rock formation in New Mexico casts doubt on theory that species was already in declineDinosaurs would not have become extinct had it not been for a catastrophic asteroid strike, researchers have said, challenging the idea the animals were already in decline.About 66m years ago, during the late Cretaceous period, a huge space rock crashed into Earth, triggering a mass extinction that wiped out all dinosaurs except birds. However, some experts have argued the dinosaurs were already in decline. Continue reading...
Study of the drink beloved by Hollywood reveals chemical difference in beans passed through civets' digestive systemIt is a coffee beloved by Hollywood and influencers - now researchers say they have found an ingredient that could help explain the unique flavour of kopi luwak.Also known as civet coffee, kopi luwak is produced from coffee beans that have passed through the digestive system of the Asian palm civet. The resulting product is not only rare, but very expensive - costing about 130 for 500g. Continue reading...
Humans have been selectively breeding animals for millennia. If we can help species survive by tweaking their DNA in a lab, I say bring it onDo you think we should genetically modify wildlife? What if we could make seabirds resistant to the flu that has been exterminating them en masse, just by tweaking their DNA a smidgen? Or make fish that can shrug off pollution, or coral that can survive warming waters? Engineer in the sorts of change that could occur naturally, given enough time, if only the wildlife would stop dying already.Thanks to newly emerging methods, such as Crispr, these feats are within reach. Recently, conservationists met at the International Union for Conservation of Nature's (IUCN) 2025 World Conservation Congress where they debated GM wildlife and voted on a proposed moratorium that would stymie their release into the wild. Ahead of the meeting, a group of more than 90 NGOs issued a press release urging the IUCN to say no to engineered wild species." But humans have been altering the DNA of other species for millennia.Helen Pilcher is a science writer and the author of Bring Back the King: The New Science of De-Extinction Continue reading...

The NHS warns against using GLP-1s while breastfeeding - for the baby's sake as well as the mother's. But how much does that count when they're so readily available and there's so much pressure to bounce back'?Lydia* first started thinking about weight-loss drugs during pregnancy. Everyone was talking about them and the advertisements were everywhere," she says, as her baby son naps upstairs. I remember thinking: That's how I'll lose weight for my wedding next year.'"When Lydia explains that most of her life before pregnancy was spent in a welter of yo-yo dieting and body dissatisfaction, I say to her that I think most of us can relate. Her pregnancy, however, brought a level of body acceptance and contentment that the 33-year-old from Wales had never had before. Continue reading...

Scientist whose research into transuranic elements revised the understanding of nuclear fissionDarleane Hoffman's research into superheavy radioactive elements at the University of California's Lawrence Berkeley National Laboratory (LBNL) and, prior to that, at Los Alamos National Laboratory in New Mexico, enhanced and extensively revised our knowledge of those elements and, consequently, our understanding of nuclear fission. Her success led, in 2002, to Discover magazine declaring her one of the 50 most important women in science.Hoffman, who has died aged 98, explored the chemical and nuclear properties of transuranic elements - those heavier than uranium. All are radioactively unstable. Most have a short half-life: existing for only a brief period before decaying, sometimes mere milliseconds. This makes them difficult to study, but, during the 1950s, Hoffman realised that characterising their properties could help us better comprehend the emerging science of nuclear fission, which involved splitting the atoms of these heavy elements to release the large amounts of energy necessary to power the first generation of commercial nuclear reactors.

In writing about my mother, Jenny Cox, I mentioned that she was refused permission to do her botany PhD research on the island of South Georgia purely because she was a woman. Though she saw this as an injustice for the rest of her life, she never revealed any details of what happened.The efficient archive service at the British Antarctic Survey have now made available a letter from Sir Vivian Fuchs dated 7 October 1959. He still wanted my mother to do UK-based lab work on existing specimens. However, he refused her or any other women access to the island, citing accommodation and severe conditions in the field.

SpaceX owner said Sean Duffy was trying to kill Nasa' after acting head said agency would reopen contracts for Artemis missionElon Musk attacked Sean Duffy, the US secretary of transportation, on Tuesday in a series of posts on X, accusing him of trying to kill NASA", suggesting he should be fired and calling him Sean Dummy". The posts intensified a long-running feud between Duffy, who is also the acting head of Nasa, and Musk, whose company SpaceX is central to the US space program.Musk's tirade against Duffy followed a statement from the transportation secretary on Tuesday that Nasa would reopen contracts for the agency's Artemis mission to land humans on the moon, which SpaceX had previously secured. Duffy said that SpaceX had fallen behind on its timelines. Duffy suggested the contract might go to another billionaire's rocket company, Jeff Bezos's Blue Origin. Continue reading...
Theoretical physicist who won the Nobel prize for his work on the forces acting on fundamental subatomic particlesChen-Ning Yang, the Chinese American theoretical physicist, who has died aged 103, won the Nobel prize in physics in 1957.It was during a period at the Institute for Advanced Study at Princeton, New Jersey, in 1950 that Yang (also known as CN Yang, or Frank Yang) befriended another young Chinese emigre, Tsung-Dao Lee. They shared the Nobel prize for work that overthrew the widely accepted parity laws" - that the forces acting on fundamental subatomic particles are symmetric between left and right. In the popular description, they overthrew the concept of mirror symmetry". Although the Nobel was for this work, performed in 1956, the most far-reaching of Yang's many contributions to theoretical physics had come earlier. Continue reading...
Iida Turpeinen's novel has been a sensation in her native Finland. On the eve of its UK publication, she talks about her compulsion to tell of the sociable giant's plightIida Turpeinen is the author of Beasts of the Sea, a Finnish novel tracing the fate of a now-extinct species: the sea cow. Similar to dugongs and manatees, the sea cow was only discovered in 1741 by the shipwrecked German-born naturalist Georg Wilhelm Steller but by 1768 it had already become the first marine species to be eradicated by humans.Translated into 28 languages and shortlisted for the country's most prestigious literary award, the Finlandia Prize, Beasts of the Sea was described by the Helsinki Literacy Agency as the most internationally successful Finnish debut novel ever. Turpeinen, 38, a PhD student of comparative literature, is now a resident novelist at Finland's Natural History Museum. Her book will be published in the UK on 23 October. Continue reading...

Why are the online far right so successful in shaping our political language? With Dr Robert TopinkaAt a press conference in September, Reform UK announced a seismic policy proposal - the end of indefinite leave to remain for immigrants. This change, which would drastically transform the UK immigration system, was justified by a supposed need to tackle the Boriswave".At first glance, the Boriswave portmanteau might be understood as merely a description of the post-Brexit pattern of heightened migration but, as the reactionary digital politics expert Dr Robert Topinka explains to Helen Pidd, the term was generated by the extremely online far right" and originally used as a racial epithet.

ITVX's perpetual real-time broadcast from the International Space Station is awe-inspiring ... until it gets boring. But even though it's hard to watch for long, it's a humbling reminder of who we areI realise that, at this point, there are already far too many shows. Every channel, every streaming service is teeming with content demanding your attention, and there are simply too few hours in the day to watch them all. However, with that in mind, may I recommend a new show called Space Live? There's only one episode. The only potential downside is that the episode literally lasts for ever.Actually, that's inaccurate. Space Live isn't a show, it's a channel. It launched on Wednesday morning, tucked away on ITVX, and consists only of live footage of Earth broadcast from the International Space Station. It's beguiling to watch, especially for anyone who didn't realise that a person can be awestruck and bored simultaneously. Continue reading...

Botanist trying to conserve highly vulnerable rhizanthella that survives by feeding on nutrients from a fungusRhizanthella is an extraordinary orchid that lives its entire life underground. It flowers below ground, has no leaves and survives by feeding on nutrients from a fungus that gets its food from the soil and by connecting with roots of the broom bush, Melaleuca uncinata.Rhizanthella was an international sensation when it was first discovered by a farmer ploughing a field in Western Australia in 1928. It still remains incredibly difficult to find, usually by searching areas with the right habitat and carefully scraping away soil searching for the blooms buried underneath - tiny reddish flowers wrapped in creamy-pink bracts. The blooms also have a heady scent of vanilla, and may be pollinated by termites or tiny flies. Continue reading...
