Science news: space, biology, climate, medicine and the research changing how we live.
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.
New research published in the Journal for the History of Astronomy says Eilmer of Malmesbury saw the same comet in 989 and 1066 — and explicitly noted it was the very same object.
Researchers tracking 130,000 adults for up to 43 years found the strongest cognitive benefits in middle-aged caffeine drinkers; effects faded for participants over 75.
The 400-billion-mile planet-forming disk around the young star IRAS 23077+6707, 1,000 light-years from Earth, is roughly 40 times wider than our solar system and unexpectedly turbulent.
Remarkably preserved Edmontosaurus fossil from South Dakota contains traces of original collagen proteins, challenging long-held beliefs about fossilization.
New research overturns Darwin-era assumptions, revealing that flower evolution speed, not pollinator specialization, drives cactus species formation.
Massive computer simulations reveal why carbon black makes rubber dramatically stronger, solving puzzle that stumped researchers for decades.
Researchers identified two enzymes that produce mitraphylline, opening the door to sustainable production of this promising anti-cancer molecule.
Researchers successfully reversed aging in blood-forming stem cells by repairing overactive lysosomes, dramatically boosting their regenerative abilities.
Researchers created algae that produce orange-scented limonene oil, allowing them to bind with water-repelling microplastics and form easily removable clumps.
Researchers created algae that produce orange-scented oil to grab microscopic plastic pollution like a magnet. The algae also clean wastewater while growing.
Lawrence Kazak's group at the Goodman Cancer Institute showed that when glycerol docks into a single binding site on the enzyme, the body's futile creatine cycle ignites and turns up the heat — a finding Nature this week called a roadmap to next-generation obesity drugs.
The probe will skim just 2,800 miles above Mars on Friday to gain gravitational boost while testing instruments and capturing rare crescent views of the Red Planet.
Adults with stage 1 hypertension who practiced baduanjin, a gentle 800-year-old mind-body routine, experienced meaningful blood pressure reductions that lasted for an entire year.
Adults with stage 1 hypertension who practiced baduanjin saw meaningful drops in blood pressure within three months that lasted for an entire year.
Researchers identify TRPV4 molecule as key component in nervous system's natural itch relief mechanism.
