A million-person study points to repeated heat injury in the oesophagus.

Un esperimento sulle esperienze extracorporee ha prodotto un risultato curioso: due partecipanti hanno descritto spontaneamente alcuni dettagli reali avvenuti in una stanza adiacente. Tuttavia, il test principale sulle immagini nascoste non ha mostrato risultati diversi da quelli attesi per caso.

Paleontologists have identified a new species of extinct alligatorid that lived in what is now Colorado just a few hundred thousand years after the asteroid impact that wiped out the non-avian dinosaurs.

New research from the Natural History Museum at the University of Oslo suggests ichthyosaurs’ rib cages may have done a job modern whale ribs don’t: acting as ballast to help them dive.

It's not what you're drinking; it's how hot it is.

Sottoponendo microscopiche gocce d'acqua a pressioni superiori a 2 milioni di atmosfere e a temperature oltre i 2.000 °C tramite celle a incudine di diamante e raggi X al sincrotrone ESRF, un team del CEA guidato da Alexis Forestier ha osservato la dominanza della fase esagonale compatta (hcp) del ghiaccio superionico. In questo stato esotico, la griglia di atomi di ossigeno rimane solida e rigida, mentre i protoni di idrogeno fluiscono liberamente conducendo elettricità. La marcata asimmetria nella conduzione termica ed elettrica di questa struttura hcp fornisce una risposta chiave per comprendere la forma anomala e inclinata dei campi magnetici di Urano e Nettuno.

The contactless version of the Korean martial art is making its debut at this year’s Asian Games. Critics say it’s a glorified video game.

For the marine archaeologist Sean Kingsley, the most honest history can be found on the seafloor.

We boiled litres of water to find the best electric kettles, from hard-water heroes to vintage-style, repairable and wifi-connected models

• The best air fryers, tried and tested for crisp and crunch

Despite the march of progress, the humble kettle remains a kitchen staple. It’s what we turn to in times of strife, when spirits are flagging, or to start our day. When a visitor calls, one of the first things we often do is put the kettle on.

Many small appliances have evolved beyond their original form, but the kettle’s basic principles remain largely unchanged. Water goes in and heats until a thermostat switches it off; the water then pours out, and we enjoy a cuppa. However, the technology that goes into a kettle has been slowly improving: better insulation to keep water hotter for longer and reduce reboils; different temperature settings to suit every drink from green tea to herbal brews; and more features such as filters and concealed elements to keep scale out of our cups.

The investigation shows that North Koreans are able to infiltrate government agencies, as well as private organizations and crypto exchanges.

The desert north of Arabia has kept a Roman military story out of sight for almost two thousand years. Now three angular traces in the landscape are giving archaeologists a possible route to follow. Researchers working with satellite imagery have identified three Roman marching camps in the Harrat al-Shaam region, close to the ancient frontier […]

An exquisitely preserved specimen of Austronaga minuta, a small, long-necked marine reptile from the Triassic of China, contains a fossilized stomach, liver and intestines, offering paleontologists their oldest detailed glimpse yet of how early reptiles digested food.

Live, rolling coverage as London’s biggest companies defy Middle East disruption and UK petrol prices rise to around £1.60 per litre, the highest since Donald Trump ordered renewed strikes

The story piquing the interest of the financial press this morning is that of Leopold Aschenbrenner, the AI Wunderkind (he’s German-born) who has been forced to sell off his fund in a fire sale after the AI boom ran out of steam.

The 24-year-old had persuaded a lot of people to give him a lot of money for a hedge fund, after previously working for OpenAI and the FTX Future Fund, a charitable arm of the fraudulent crypto empire of Sam Bankman-Fried, who is now in prison. Aschenbrenner ploughed that money into debt-fuelled bets on artificial intelligence companies, earning huge returns until he found out that stocks can also fall.

The trader dubbed the “Nostradamus of AI” would have been hard-pressed to foresee how quickly his high-flying hedge fund would run into trouble.

The firm’s rapid downward spiral is a familiar tale, as Silicon Valley and Wall Street once again threw their weight behind a bright-eyed but untested investor who promised this time would be different. “Everybody always wants to find the next golden child,” said one longtime hedge fund executive. “It just keeps happening.”

In less than 24 hours — which included a conversation between Griffin and Aschenbrenner — Griffin’s Citadel hedge fund reached out to Situational Awareness and snapped up the investments at a discount, according to a person familiar with the matter who asked not to be identified citing private information.

It was a startling reversal for Aschenbrenner, a former researcher at OpenAI who – before starting his hedge fund roughly two years ago — had no previous investment experience. His fledging firm has watched its assets plunge from $45bn at the start of July to about $10bn.
