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 ...

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.

NASA is preparing for future astronaut landings on the Moon with an unusually ambitious orbital rehearsal. During Artemis III in 2027, Orion astronauts will rendezvous and dock separately with prototype lunar landers from Blue Origin and SpaceX, ...

A giant planet had been hiding inside one of astronomy's most closely studied planetary systems, concealed by a bright disk of cosmic dust. Webb revealed Beta Pictoris d through atmospheric traces of carbon monoxide, water vapor, and methane, ...

Researchers discovered a proton-assisted mechanism that greatly improves how triplet energy moves between quantum dots and nearby molecules. The proton briefly shifts position, helps coordinate electron movement, and then returns to where it started. ...

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 .. ...

Researchers are applying evolutionary theory to cancer by changing treatments before tumors have time to develop resistance. Mathematical models suggest that rapid, carefully timed switches between multiple therapies could improve cure rates.

Scientists have created a programmable optical chip that can slow light on demand, giving engineers far greater control over how optical signals propagate through a circuit. The technology could provide the delays, synchronization, and buffering ...
