Astronomers may have witnessed one of the rarest and most dramatic cosmic events ever seen: a long-sought intermediate-mass black hole ripping apart a dense white dwarf star and devouring it。 The Einstein Probe space telescope caught the explosion in its earliest moments, revealing an unusual sequence of intense X-ray flashes unlike anything seen i

Simo, who was Sam Altman’s second in command before taking a medical leave in April, will become a part-time adviser to the company
Scientists have uncovered new evidence that fireworks can pollute both the air and water in ways that extend beyond the visible smoke。 The findings show that leftover debris, fine particles, and airborne chemicals may affect ecosystems and increase people's exposure to air pollution during major celebrations
Researchers have proposed that black holes stop evaporating at the last moment, leaving behind tiny remnants that preserve all the information they contain。 The same seven-dimensional geometry behind this idea could also help explain why elementary particles have mass
A new quantum device can generate precisely controlled bursts of sound-like particles, or phonons, by forcing electrons through an ultra-thin crystal at extremely low temperatures。 The surprising behavior pushes beyond the limits predicted by current theories, suggesting scientists need to rethink how energy moves through advanced materials。 In the
A new quantum theory bridges two rival models of how impurities behave inside many-particle systems, resolving a problem that has challenged physicists for decades。 The findings could reshape experiments on ultracold atoms, semiconductors, and other exotic forms of quantum matter
Researchers have shown that ultracold atoms can be driven into a strange new quantum state called a fractional Fermi sea, where particles organize themselves in unexpected ways。 The discovery points to a new phase of matter that goes beyond established quantum theories and could expand the possibilities of quantum simulation
A rare meteorite has revealed evidence of a massive lost world that once orbited the young Sun before being destroyed in a catastrophic collision。 The discovery suggests some early planets formed from dramatically different materials than Earth and Mars, rewriting part of the solar system’s origin story
The move comes after Simo took significant medical leave。 She will stay on as a part-time adviser
For the first time, the company will offer a paid version of the service, a departure from its longtime philosophy of giving its A。 away for free
The layoffs were part of wider cuts at Microsoft, as the company prioritizes spending on artificial intelligence
Hawaii researchers are giving old fishing nets and recycled plastic a second life by mixing them into asphalt roads。 Early tests found these roads didn't release more plastic particles than standard pavement, with tire wear overwhelming any plastic signal from the recycled material。 If future studies confirm the roads are durable, the technology co
We've spent the good part of this past year building an AI tutor that teaches kids ages 4-9 reading, math, ESL and more。 Getting an AI tutor to effectively teach a child turns out to be a really hard technical challenge, this took getting the underlying architecture right。Our tutor steers the UX in real-time and makes complex decisions on the fly
Scientists have rewritten the story of gallium after discovering that its unusual atomic bonds re-form at high temperatures, contradicting decades of accepted theory。 The finding changes how researchers explain why the metal melts so easily and behaves unlike almost any other metal。 Beyond solving a long-standing scientific mystery, the work could
A surprising discovery is reshaping scientists' understanding of how humans develop sharp central vision before birth。 Instead of blue cone cells migrating away from the retina's center, the study found they transform into red and green cones under the influence of vitamin A-related signals and thyroid hormones。 The findings could improve lab-grown
Creatine is best known as a muscle-building supplement, but scientists are now investigating whether it could also help treat depression by boosting the brain's energy supply。 A new review examined five randomized clinical trials involving 238 participants and found mixed results。 Two studies, both involving women with major depressive disorder, re
A few days ago I found myself trying out GLM 5。2 and was really positively impressed。 The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me
Scientists have finally solved a nearly 30-year-old mystery surrounding two unusual molecules found in rye pollen that once showed an intriguing ability to help animals fight tumors。 By determining their exact 3D structures, researchers have unlocked the blueprint needed to investigate how these natural compounds interact with the immune system and
