Cosmic expansion allows distant galaxies to move away faster than light, while still letting us see ancient light they emitted when they were much closer. Eventually, accelerating expansion will push nearly every galaxy beyond our Local Group out of ...

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 ...

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 ...

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 ...

Stanford Medicine researchers have discovered a naturally occurring molecule that may suppress appetite and reduce body weight much like Ozempic, but without several of its common side effects. The molecule, called BRP, acts on a more targeted region ...

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 ...

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 newly identified fossil ape from northern Egypt is reshaping ideas about where the ancestors of modern apes first emerged. Analyses place it closer to living apes than any known East African species of the same age, pointing to North Africa and the ...

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 ...

Fossils discovered in Japan more than two decades ago have finally been identified as a new genus and species of giant salamander. Limnospondylus ajimuensis lived around 3.5 million years ago in a warmer, wetter Kyushu and may have reached 1.1 meters ...
