The longevity-linked APOE2 gene appears to protect brain cells by reducing DNA damage and helping neurons recover from stress。 The finding could open a new path toward treatments that mimic APOE2’s defenses in people at higher genetic risk for Alzheimer’s

Sweden could become an important source of rare earth elements needed for magnets and green technologies。 Instead of extracting one target metal, researchers are cataloging everything contained in Swedish mineral deposits。 They will then develop magnets using those naturally available combinations, potentially reducing pollution, waste, and relianc

Newer oral drugs related to semaglutide medications such as Ozempic reduced pleasure-driven eating in mice by quieting a deep brain reward circuit。 The finding could open new avenues for understanding food cravings and potentially treating substance use disorder

It can be unsettling what Gemini and ChatGPT have figured out about you and how easily your privacy can be punctured。 Here’s how to find out

As major tech companies race to capitalize on a new wave of AI technology, investors wonder when financial benefits will appear

MIT engineers have found a way to give chip-based lidar a wider, clearer view without relying on moving parts。 Their design uses differently shaped antennas that can sit close together without scrambling one another’s signals。 In tests, the system sharply reduced interference while steering a single precise beam across a broad field of view

Scientists have uncovered new evidence that Venus may still be tearing itself apart from within。 Advanced 3D simulations indicate that some of the planet's giant rift valleys formed relatively recently and could still be expanding。 The results suggest Venus has a far more active interior than researchers once believed, challenging the long-held vie

The Backrooms began as a single eerie image of empty yellow rooms, but internet users transformed it into a vast fictional world that feels disturbingly real。 Through videos, games, maps, survival guides and social media stories, audiences do more than watch the horror unfold。 They help build and explore it

A new analysis suggests the Sun holds far more silver than earlier estimates indicated。 More advanced models of the solar atmosphere raised the calculated amount by 55 percent, bringing it into much closer agreement with ancient meteorites。 The technique may also help scientists track the cosmic origins of silver and other heavy elements

China’s Tianwen-1 orbiter captured a faint but remarkable view of 3I/ATLAS as the interstellar comet raced past Mars。 The images reveal its tail and glowing coma, offering scientists a glimpse of material born beyond our solar system

A notorious snake invasion that devastated Guam’s native birds may have succeeded because the reptiles carried hidden genetic advantages。 Using advanced long-read DNA sequencing, researchers uncovered more than 19,000 large genetic differences in brown tree snakes, many concentrated in genes tied to immunity and smell。 This overlooked diversity may

"We can quash the subpoenas, or you could withdraw the subpoenas,” judge told US

More electric vehicles are becoming capable of providing backup power at a time when the US is increasingly in need of more electrons

Researchers say a tiny one-eyed ancestor that lived nearly 600 million years ago may have shaped the evolution of every vertebrate eye, including our own。 They also found that its ancient median eye lives on today as the pineal gland, which helps synchronize our sleep with daylight

The Silicon Valley chipmaker’s revenue rose 25 percent in the latest quarter, its fastest growth in 15 years, as A。 firms increasingly bought chips known as central processing units

Popular AI-powered food apps may make calorie counting easier, but they may also leave out a surprisingly large part of the meal。 Four apps underestimated calories and fat by about one-third when tested against carefully prepared meals。 High-fat ketogenic dishes appeared to cause the most trouble, while carbohydrates were measured more consistently

Recycling, greener diets, and other personal climate choices do not seem to distract people from supporting major environmental reforms。 A four-year study of nearly 2,800 Australians found that these habits neither increased nor reduced later political engagement

The technology, often associated with pandemic-era menus, is being used by more couples for ease, cost, expedience and sustainability

More than 1,000 illegal streaming sites were shut down in the US during the tournament, with a similar amount blocked in Colombia

Anthropic and OpenAI are clashing with the rest of the tech industry over whether “open-source” models from China should be freely available or restricted
