A distant Sun-like star appears to have devoured one of its planets, leaving behind a surprising chemical fingerprint。 Researchers found an unusually high concentration of lithium, a strong sign that planetary material was mixed into the star。 Careful comparisons with dozens of similar stars confirmed the signal is highly unusual, and scientists th
Researchers have uncovered a surprising culprit behind sleep loss in Alzheimer’s disease: the brain’s own immune cells。 In mice with amyloid plaques, overactive microglia triggered inflammation that kept the brain from getting enough deep, restorative sleep。 Temporarily removing most of these cells restored more than two hours of sleep per day, eve
A study of 225 newborns suggests prenatal estrogen may have played a role in the evolution of larger human brains。 Boys with finger-length patterns linked to higher estrogen exposure before birth tended to have larger head circumferences, which are strongly associated with brain size。 The same connection was not seen in girls
Someone used A。 to write my biography。 Thousands more of those books are polluting Amazon
Meta's release this week of an AI feature that let people alter Instagram content drew swift blowback
The lawsuit highlighted concerns that the privacy of Apple’s iCloud allows illegal material to be easily stored and shared on the service
The first tweets from the public appeared on July 15, 2006, several months after a soft launch。 It was rebranded as X after being acquired by Elon Musk
Don't eat Taco Bell lettuce in Indiana, Kentucky, Michigan, Ohio, or West Virginia
The Chinese retailer allowed unsafe toys and counterfeit clothes to be sold on its site, says the EU
Apple said in a Friday lawsuit that OpenAI’s nascent hardware business is “rotten to its core
Researchers have created cosmic dust from scratch by recreating space-like conditions inside glass tubes。 The dust contains complex carbon-rich molecules built from elements essential to life and produces infrared signals similar to real material found in space。 By studying these laboratory samples, scientists can explore how organic chemistry unfo
Michael Steranka, vice president at the mobile game's owner Scopely, says it has always been about bringing people together
A new AI-powered blood test could give people a remarkably early warning of serious heart and circulation problems。 Developed by researchers at the University of Hong Kong, CardiOmicScore analyzes thousands of proteins and metabolites to estimate the risk of six major cardiovascular diseases, including heart attack, stroke, heart failure, and atria
A team of mathematicians used whimsical "silly sprinklers" to solve a physics mystery that has puzzled scientists for decades。 Their experiments showed that the rotation of both normal and reverse sprinklers is driven by the momentum of flowing water, not by the outside water flow or other long-standing theories。 The results finally provide a clear
A low-cost antidepressant may offer new hope for people struggling with long COVID fatigue。 In a randomized clinical trial involving 399 adults, fluvoxamine significantly reduced fatigue and improved quality of life compared with a placebo, making it one of the first medications to show meaningful benefits for this disabling condition
A new particle detector called PLATON could replace millions of tiny detector components with a single block of light-producing material。 Using a light-field camera, highly sensitive photon sensors, and AI, it reconstructs particle paths in fast, detailed 3D。 Simulations suggest it could match or surpass today’s best detectors while being far easie
A power auction conducted by a giant grid operator is expected to add $6。3 billion in additional charges to consumers and businesses because of electricity needs of data centers
JWST has captured unusually detailed images of gas feeding the supermassive black hole at the center of NGC 4696。 A vast filament appears to funnel material into an 800-light-year-wide spinning disk, where gas races around at up to 600 kilometers per second。 The findings suggest black holes may recycle their own fuel by heating gas with jets and la
