Science news: space, biology, climate, medicine and the research changing how we live.
A routine drill into a sandstone slab nicknamed 'Atacama' lifted the entire chunk out of Gale Crater and stuck it to the rover's drill sleeve — an annoying first that handed scientists their first ever look at pristine, unweathered Martian bedrock from below.
Bird bander's casual iNaturalist upload leads to identification of rare Ptilotus senarius, proving citizen science's growing importance in biodiversity research.
World Institute of Kimchi scientists show Leuconostoc mesenteroides CBA3656 binds 87 percent of polystyrene nanoplastics and keeps 57 percent capacity inside the human-like gut.
Lead author Rosalie Sears shows phosphorylated MYC physically migrates to damaged DNA in tumor cells, opening a new combination strategy with first-in-class inhibitor OMO-103.
The Institute for Bioengineering of Catalonia turns the brain's own LRP1 transport system into an active drug — and treated 18-month-old mice behave like healthy younger animals six months later.
Ptilotus senarius, missing since 1967, was spotted by bird bander Aaron Bean and identified by botanist Anthony Bean through iNaturalist observations.
A new Nature Geoscience paper combines 22 years of TIMED and SABER satellite data with refined radiative-transfer models to show how the upper atmosphere has shrunk visibly as carbon dioxide climbs.
A comparative analysis of 2,025 individuals from 41 primate species, published in PLOS Biology, shows that bipedal proportions and relative brain size together fully account for humans' unique species-wide hand preference.
The magnetoplasmadynamic engine ran 25 times more powerful than the thrusters now flying on the Psyche mission, hitting tungsten temperatures above 5,000°F and marking the highest-power electric propulsion test ever conducted in the United States.
Breakthrough treatment restored brain's natural cleanup system and cleared toxic proteins, with elderly mice behaving like healthy younger animals.
Paleontologists in Teruel province have recovered the most complete Dacentrurus armatus skull ever found in Europe and proposed an entirely new evolutionary group, Neostegosauria, to make sense of where the plated dinosaur fits on the family tree.
A Curtin University-led expedition aboard the Schmidt Ocean Institute's Falkor mapped 226 species in two remote submarine canyons off the Ningaloo coast — including six separate environmental DNA hits on the elusive Architeuthis dux.
Sifting through millions of meteor sightings, researcher Patrick Shober identified 282 fireballs that share an extreme orbit — evidence of a hidden Sun-grazing asteroid disintegrating in the inner solar system, with implications for planetary defense.
A study in Nature Communications shows Pilea peperomioides arranges its leaf veins as a Voronoi diagram, the same mathematical pattern engineers use to optimize networks.
A modified pyrimidone molecule absorbs sunlight, locks it away as chemical strain, and releases it later as heat on demand — at 1.6 megajoules per kilogram.
Researchers tracked steroidogenic factor-1 neurons in the hypothalamus that stay active for an hour after exercise and appear to be the brain's 'endurance trainer.'
A new Astronomy & Astrophysics study finds that the soon-to-launch Nancy Grace Roman Space Telescope will be sensitive enough to weigh isolated neutron stars through gravitational microlensing, finally cataloguing the city-sized stellar corpses that have eluded detection for nearly a century.
JPL says its High-Performance Spaceflight Computing processor, built jointly with Microchip Technology, has cleared early radiation testing well beyond its 100x design target and is on track to fly on Artemis lunar missions and Mars Sample Return.
Thirteen teeth excavated from Ethiopia's Ledi-Geraru badlands reveal that the earliest humans co-existed with a previously unnamed small-bodied Australopithecus, overturning the textbook image of a single linear march from ape to human and reshaping the early Homo family tree.
A 30-year mystery of why a remote undersea fault off Ecuador produces magnitude-6 quakes like clockwork has been solved: pore-pressure barriers in fluid-soaked rock slam the brakes on each rupture before it can spread, a Science study reports.
Engineered nanoparticles restored brain cleanup systems and cleared toxic proteins, with elderly treated mice later behaving like healthy younger animals.
Scientists revealed a 3-million-light-year filament connecting galaxies from 12 billion years ago, offering new insights into how galaxies form and evolve.
Astronomers capture the clearest view of a cosmic filament stretching 3 million light-years, offering insight into how galaxies formed 12 billion years ago.
A major analysis found that people with anxiety disorders have significantly lower choline levels in their brains, potentially pointing toward new nutrition-based treatments.
Synthetic aptamers screened from 100 trillion random sequences could finally let drugs destroy senescent cells without harming healthy tissue, opening a new front against Alzheimer's and arthritis.
Shalbatana Vallis stretches 1,300 kilometers across Mars, carved by ancient floods that may hint at a lost ocean near the planet's equator.
Nagatitan chaiyaphumensis weighed 27 tonnes and may be Southeast Asia's final giant sauropod before seas transformed the region.
Scientists discover serotonin-driven brain circuit linked to tinnitus-like behavior, potentially explaining why SSRIs can increase ear ringing.
Scientists find compelling evidence that Edmontosaurus fossil retains original collagen proteins, overturning long-held beliefs about fossilization.
Scientists analyzing thousands of genomes discovered evidence for a previously unknown third ancestral group, challenging the long-accepted 'dual origins' theory and revealing Japan's hidden genetic diversity.
