Numa semana histórica para o setor da inteligência artificial, a OpenAI submeteu o seu prospeto confidencial à SEC dias depois da Anthropic ter feito o mesmo. A SpaceX prepara-se para começar a negociar na bolsa ainda esta semana. E a Perplexity, imperturbável, mantém o seu plano para 2028.
NASA's Artemis II crew are the fastest people alive, and now they have the patch to prove it.
Mission Commander Reid Wiseman, pilot Victor Glover, and mission specialists Christina Koch and Jeremy Hansen (the latter with the Canadian Space Agency) spent 10 days in early April flying by the Moon. Their journey took them farther away from Earth than any humans have gone (52,756 miles [406,771 km]) and then, on the way back on board their Orion spacecraft Integrity, they sped up to about 24,664 miles per hour (39,693 k/ph) reentering the atmosphere.
Only three other people in history have traveled faster. NASA's Apollo 10 astronauts Thomas Stafford, John Young, and Eugene Cernan set the record for the highest speed attained by a crewed vehicle relative to the Earth's surface: 24,791 mph (39,897 kph) on May 26, 1969.
Geochemical analysis of 780,000-year-old stone tools from Israel suggests Acheulean (or Acheulian) hominins repeatedly sought specific basalt sources, revealing sophisticated planning and deep knowledge of their landscape.
Ötzi the Iceman, Europe’s most famous mummy, is crawling with microbes, some long dead, some still eking out a living after thousands of years, and some very modern.
After he died in the Ötztal Alps, the Copper Age man now known as Ötzi lay alone and forgotten for 5,300 years, until a group of hikers stumbled on his freeze-dried remains in 1991. Since then, he’s received a lot of attention from scientists, who have sequenced his DNA, pored over his last meal and the remains of his gut microbes, and examined his clothes and his broken tools. Today, Ötzi lies in a high-tech resting place at the South Tyrol Museum of Archaeology in Italy, where, it turns out, his body is still home to a handful of cold-adapted yeast species that have probably been with him since just after he died.
Slightly morbid souvenirs from the Alps
Microbiologist Mohamed S. Sarhan (of the Institute of Mummy Studies at the private Eurac Research center) and his colleagues recently sampled material from Ötzi’s stomach and meltwater from inside his body, swabbed his skin, and even sampled airborne microbes from his frozen storage room and the lab outside it. They also took samples from a block of frozen alpine soil taken from next to Ötzi’s body back in 1991.
Neolithic people, not glaciers, moved the Altar Stone -- the six-ton central sandstone megalith at Stonehenge -- from northeast Scotland to Salisbury Plain, according to a new study led by archaeologists from Curtin University and Sheffield Hallam University.
He mapped the herpes simplex virus genome, revealing how it invades cells. His work also helped lay the groundwork for potential vaccines and gene therapies.
Ação inédita acusa a OpenAI de ocultar os perigos do ChatGPT para os menores em prol do lucro. O processo surge numa vaga de litígios nos EUA que já resultou em multas milionárias para gigantes como a Meta e a Google.
The state became the first to sue the ChatGPT maker over claims that its technology posed a risk to children and that the company had failed to warn the public of dangers.
In a small randomized trial in the United Kingdom, adults who added a serving of 100% fruit juice or a smoothie to a healthier diet reported lower depression scores after four weeks.
In a small clinical trial, researchers at the Ohio State University found that a tomato juice rich in lycopene and soy isoflavones lowered several proteins linked to chronic inflammation, raising hopes for food-based therapies.
New research led by scientists from the French National Institute for Agriculture, Food, and Environment (INRAE) suggests cows (Bos taurus taurus) can distinguish between known and unknown people, and even match a familiar voice to the correct face.
New research from the University of Oxford and the University of Reading suggests bipedalism and expanding brain size helped drive the overwhelming dominance of right-handedness in humans.
