Scientists discover hidden chemical signature that could reveal alien life
Living systems may leave behind a universal chemical fingerprint that distinguishes them from nonliving matter — and scientists think it could be detectable across the cosmos. Rather than hunting for specific molecules, researchers identified consistent statistical patterns in how amino acids and fatty acids are organized, patterns that appear unique to life. The finding could fundamentally reshape how space missions search for biosignatures on other worlds.

NASA fuel cell tests pave way for energy storage on the moon
NASA has successfully tested a fuel cell system packed with nearly 270 sensors and 1,000 components, marking a significant step toward sustainable energy storage on the lunar surface. The technology is critical for surviving the moon's two-week-long nights, when solar power becomes unavailable. If scaled for deployment, it could underpin long-term human presence on the moon.

A supervolcano nearly wiped out humanity 74,000 years ago, but humans did something incredible
The Toba supervolcano eruption 74,000 years ago ranks among the most catastrophic events in human history, likely triggering years of volcanic winter and prompting early theories of a near-extinction bottleneck. But mounting archaeological evidence tells a different story. Far from being wiped out, early human communities across Africa and Asia adapted through innovation — developing new tools and survival strategies that underscore the species' extraordinary resilience under pressure.

James Webb telescope reveals the clearest map ever of the Universe’s cosmic web
The James Webb Space Telescope has produced the sharpest map ever made of the cosmic web, the vast invisible scaffolding of filaments and voids that links galaxies across the universe. Drawing on data from over 164,000 galaxies through the COSMOS-Web survey, researchers traced this structure back to just one billion years after the Big Bang. The findings offer an unprecedented look at how the large-scale architecture of the universe first took shape.

Method for measuring energy amounts less than a trillionth of a billionth of a joule could boost quantum computing
Researchers have developed a method capable of measuring energy at scales below one trillionth of a billionth of a joule — a level of precision that pushes the boundaries of quantum measurement. Such granular control over minuscule energy transfers, including those carried by individual photons, opens new pathways for advancing quantum computing hardware. The technique may also prove valuable in the search for dark-matter axions, among the most difficult-to-detect particles in the universe.
