Scientists found that prolonged fasting triggers major changes throughout the body, but many of the most interesting effects only appeared after about three days without food. The results suggest ...

Researchers found that just 20 minutes of comfortable walking can rapidly stimulate the gut. Within one to two minutes after ...

NASA has selected the GIMLI project to investigate whether the Marius Hill Pit opens into a vast underground cave or lava tube. Using radar, seismic sensors, gravity measurements, and cameras, ...

Scientists have discovered evidence of altermagnetism in a thin, highly tunable material that could help electronics use electron spin instead of relying only on electrical charge. The unusual ...

October skywatchers can see Saturn at opposition, catch meteors from Halley’s Comet during the Orionid peak, and watch the Moon sweep past the famous Pleiades star cluster. Moonlight may obscure some ...

A new nanoparticle therapy reduced lung tumors in mice while also targeting cachexia, the severe muscle wasting that can accompany cancer. By delivering follistatin mRNA directly to tumors, the ...

Scientists have discovered a previously unknown fossil goose that challenges a decades-old theory about the evolution of New Zealand's birds. The find suggests the country's giant flightless geese ...

Scientists have discovered a human gene with a remarkable double life: it appears to play an important role in brain cells while still retaining the ability to jump around the genome. Called BC200, ...

Stimulating the vagus nerve after practice helped mice develop stronger long-term motor learning, revealing a potentially important window when the brain is still locking in a new skill. The effect ...

Cancer immunotherapy can lose its punch when tumor-fighting T cells become exhausted, but researchers may have found a way to keep them going longer. Scientists at Memorial Sloan Kettering Cancer ...

A spectacular 150-million-year-old trail of more than 130 footprints captures a giant sauropod making a complete loop before continuing on its way. Its uneven stride hints that the long-necked ...

Scientists in Sweden have taken a major step toward a potential cure for type 1 diabetes by developing a more reliable way to create insulin-producing cells from human stem cells. These lab-grown ...
