A powerful new electromagnetic thruster has taken a major step forward after a successful high-energy test at NASA's Jet Propulsion Laboratory. Fueled by lithium vapor and driven by intense magnetic forces, the experimental engine reached record ...

MIT neuroscientists have uncovered a surprising secret hidden in the adult brain: millions of "silent synapses," dormant connections that lie in wait until new learning calls them into action. Once thought to exist only in early development, these .. ...

A forgotten fossil hidden inside a garden wall has turned out to be one of Australia's most remarkable prehistoric discoveries. Scientists have now identified the 240-million-year-old amphibian, Arenaerpeton supinatus, revealing an almost perfectly . ...

Oak trees have a surprising trick to fight back against hungry caterpillars: they simply wait. When trees are heavily attacked one year, they delay leaf growth by just three days the next spring--long enough to leave newly hatched caterpillars with . ...

A scorching, airless world just 48 light-years away is offering scientists a rare glimpse into the geology of distant planets. Using the James Webb Space Telescope, researchers studied LHS 3844 b--a tidally locked "super-Earth" with a permanent ...

Creating complex molecules usually requires years of experience and countless decisions, but a new AI system is changing that. Synthegy lets chemists guide synthesis and reaction planning using simple language, while powerful algorithms generate and ...

A surprising genetic twist shows that boosting a seemingly ordinary "housekeeping" gene can dramatically improve fruit quality without any trade-offs. By increasing the activity of a tRNA-related gene in strawberries, researchers unlocked richer ...

Astronomers have spotted something surprising in the far outer Solar System--a faint, short-lived atmosphere clinging to a tiny icy world that shouldn't be able to hold one at all. The object, called 2002 XV93, is far smaller than Pluto, yet ...

Tyrannosaurs may be famous as fearsome apex predators, but new research reveals a more opportunistic--and slightly grim--side to their behavior. Using high-resolution 3D scans, a researcher identified precise bite marks on a massive tyrannosaur foot ...

Long-forgotten ancient tablets have been decoded, uncovering a mix of magic, politics, and daily life from early civilizations. Among the discoveries are rare anti-witchcraft rituals meant to protect kings and a regnal list that could point to the .. ...
