A strange kind of matter that “ticks” forever without energy input has just taken a major leap toward real-world use. Known as a time crystal, this quantum system repeats its motion endlessly—like a clock that never winds down—and scientists have...
Tyrannosaurs may be famous as fearsome apex predators, but new research reveals a more opportunistic—and slightly grim—side to their behavior. Using high-resolution 3D scans, a researcher identified precise bite marks on a massive tyrannosaur foot...
Na manhã de 5 de maio de 1961, Alan Shepard, de 37 anos, acordou, tomou um café da manhã (composto por filé mignon envolto em bacon, ovos mexidos e suco de laranja), amarrou-se no foguete Freedom 7 e decolou para o espaço, tornando-se o primeiro...
Anthropic has spent years building itself up as the safe AI company. But new security research shared with The Verge suggests Claude's carefully crafted helpful personality may itself be a vulnerability. Researchers at AI red-teaming company...

After centuries of mystery, scientists are edging closer to uncovering Leonardo da Vinci’s biological secrets. A massive 30-year effort has mapped his family across 21 generations, identified living male descendants, and even confirmed shared DNA...
Artemis II proved NASA’s deep space systems are ready for the next leap. Orion survived its high-speed return with improved heat shield performance and pinpoint landing accuracy, while the SLS rocket nailed its trajectory. Even the launch pad...
A new analysis of the “Boltzmann brain” paradox suggests our memories and sense of reality could, in theory, be random illusions born from cosmic chaos. By uncovering circular reasoning in how physicists think about time and entropy, the study...
O governo de Hong Kong criticou na sexta-feira a mídia estrangeira e os grupos de liberdade de imprensa, rejeitando as alegações de repressão à liberdade de imprensa como “calúnia” depois que o magnata da mídia preso Jimmy Lai recebeu um prêmio de liberdade de expressão na Alemanha. Liberdade de imprensa na cidade...
Astronomers have unleashed a powerful new AI tool called RAVEN to comb through data from NASA’s TESS mission—and it’s paying off in a big way. By analyzing millions of stars, the system has confirmed over 100 exoplanets, including 31 brand-new...
Crushing soda cans for science, why dolphins swim so fast, how urine helps mushrooms communicate, and more
Scientists have discovered a way to help the brain clean itself of harmful Alzheimer’s plaques by activating its own support cells. By increasing a protein called Sox9, researchers were able to boost the activity of astrocytes, star shaped cells...
Two of the most dangerous fault systems on the U.S. West Coast may be more connected than scientists once thought. New research suggests the Cascadia subduction zone and the San Andreas fault can “sync up,” triggering earthquakes within minutes or...
Actors and writers created by artificial intelligence may be able to write and appear in films, but they will not qualify for Oscars under new rules issued by the Academy of Motion Picture Arts and Sciences, which address the use of AI for the first...
Sur le littoral normand, si des acquéreurs très fortunés continuent de s’arracher des maisons avec vue sur mer, les prix commencent à prendre en compte les risques littoraux. Certains clients préfèrent désormais des habitations en retrait.

Building muscle doesn’t have to mean exhausting workouts or soreness. Researchers found that slow, controlled “lowering” movements can boost strength more efficiently while requiring less effort. Even five minutes a day of simple exercises like...
Deep in a dried-up riverbed in Brazil, scientists uncovered a bizarre prehistoric mystery—twisted jawbones from a strange, long-lost animal unlike anything seen before. Dating back 275 million years, this creature, named Tanyka amnicola, belonged to...
