Quatre fois plus vite qu'un bébé humain. C'est la vitesse à laquelle un chat associe un mot à une image. Une étude japonaise vient de démonter une idée bien ancrée : relier les mots au monde réel ne serait pas l'apanage des primates. Votre chat vous écoute. Il a juste décidé de ne pas vous le...
Domestic cats (Felis catus) develop the same patterns of brain shrinkage and neurological decline as aging humans, and scientists think that makes them an ideal window into dementia and aging.
Tesla and independent energy firm NatPower have reached a deal to build 25 gigawatt-hours of battery storage in Italy and Britain, the first phase of a program worth up to $5 billion.
Under the multiyear agreement, NatPower will deploy Tesla’s Megapack systems and use Tesla’s trading software to decide when to buy and sell electricity — extending Tesla’s reach deeper into Europe’s fast-growing grid storage market.
Depuis des siècles, la mer et la pierre dialoguent sur la côte sarde, mêlant leurs voix entre les vestiges de Tharros. Parmi les colonnes brisées et les dalles blanchies par le soleil, le vent s’engouffre, porteur de récits oubliés. À chaque marée, les vagues effleurent les ruines antiques,...
For our weary eyeballs, strained and tired from long periods locked onto screens, rest and relaxation can do wonders. But a man in Scotland came up with an eye-popping plan to try to pamper his pooped peepers.
Ophthalmologists discovered it when the man, who was in his 20s, appeared at an eye treatment center in Edinburgh. He told them he had noticed increasing floaters and flashing lights in his right eye over the previous six days. According to a BMJ Case Report, the man said he hadn't had any eye or head injuries before the vision problems began, and that his family didn't have a history of eye disorders that might explain them. Besides having mild near-sightedness and needing glasses, he usually didn't have any problems with his eyes, he said.
When the doctors—Niamh O’Connell and Ashraf Khan—took a close look, they were surprised to find that both of his eyes were in terrible shape. In his right eye, he had multiple retinal tears, widespread retinal bruising, and a condition called retinal dialysis—a retinal break at a junction in the front of the eye—that is usually seen after a significant eye injury. In his left eye, he had more widespread bruising and six full-thickness rips in his retina.
The White House recently endorsed monitoring sewage for evidence of drug use. Critics fear such efforts could violate privacy and stigmatize neighborhoods.
Canada : L’eau du lac Peyto s’étire en une étendue turquoise, éclatante comme un joyau niché au creux des Rocheuses. Tout autour, les forêts sombres montent la garde, dressant leur ombre sur les rives tandis que les glaciers lointains déposent sur la surface leurs éclats de lumière cristalline....
Pas de virus sur les postes, pas de trafic suspect, aucune faille exploitée pour le vol : un groupe lié à la Chine a siphonné des courriels sensibles pendant plus d'un an grâce à une simple fonction d'administration de Google Workspace.
Gum disease is one of the most common health problems in adults. Many people experience bleeding gums, bad breath, or swollen gums at some point in their lives. However, for some people, the disease becomes much more serious. A severe form of gum disease called periodontitis can slowly destroy the tissues that support the teeth. […]
Depuis des années, les scientifiques soupçonnent certaines bactéries intestinales de favoriser le cancer colorectal. Mais une nouvelle étude révèle qu’elles pourraient elles-mêmes être manipulées par un acteur jusqu’ici passé sous les radars : un virus caché dans leur ADN. Une découverte qui...
Exceptionally preserved skin of Montsecosuchus depereti, an extinct crocodylomorph no larger than a house cat that prowled the tropical wetlands of Early Cretaceous Spain, has allowed paleontologists to reconstruct details of its scales, sensory organs and even possible banded markings along its tail.
