Debris released from the asteroid Dimorphos during NASA's DART mission has a higher momentum and less random distribution than expected, which "changes the physics we need to consider when planning these types of missions," researchers say.

New simulations have narrowed down where the newly discovered interstellar comet 3I/ATLAS likely came from, revealing it could be more than 3 billion years older than the solar system.

The psychedelic psilocybin, found in magic mushrooms, slows certain hallmarks of aging in human cells and older mice, a lab study suggests.

Researchers have created an ultrasensitive laser the size of a penny that could improve lidar technology, boosting autonomous vehicles in the process.
