Science news: space, biology, climate, medicine and the research changing how we live.
Researchers tracking three generations of mice found hundreds of cases where chemical DNA marks were passed down in ways classical genetics says should be impossible — including the first naturally occurring mammalian paramutation.
The experimental jet, built to replace the sonic boom with a soft 'thump,' is set to go supersonic in early June, a milestone that could one day return high-speed passenger flight to the skies over land.
New images from the Hubble Space Telescope show the galaxy losing its star-forming gas as it races through the dense cluster, a process that is slowly snuffing out its ability to build new stars.
Scientists hauled laser scanners through more than 10 kilometers of remote caves to map the karst aquifer feeding Roaring Springs, finding that water can travel 20 kilometers underground in as little as a week.
Researchers found that disabling NFIL3 keeps engineered immune cells stronger for longer and improves tumor control in animal models.
Using Australia's ASKAP telescope, a team traced a baffling repeating signal to a white dwarf devouring its companion star — emitting bursts every 1.4 hours that are 100 times more powerful than any seen before.
Scientists report that iron-loaded immune cells in the pigeon liver may act as tiny magnetic sensors, helping the birds read Earth's magnetic field — a finding one researcher called 'mind-blowing.'
University of Birmingham researchers say their perovskite catalyst, built from cheap and non-toxic metals, could make hydrogen for less than today's 'green' and 'blue' methods by harnessing heat factories already throw away.
Researchers identified NFIL3 as a major obstacle causing engineered immune cells to become exhausted and lose their cancer-fighting power, offering new hope for improving treatment of solid tumors.
A topical dose of the senescence-clearing drug ABT-263 rejuvenated old skin in mice and closed wounds faster, pointing toward new treatments for surgery and chronic injuries in older adults.
A team at UC Riverside and the Weizmann Institute found that living chemistry spreads amino acids more evenly than non-life — a test that could be run on data from Mars, Europa and Enceladus.
A Cornell researcher's walk through an Ithaca graveyard uncovered a sprawling underground 'city' of solitary mining bees that may have thrived in the sandy soil for more than a century.
Astronomers used the James Webb Space Telescope to show that Saturn's apparently shifting rotation rate was an illusion created by powerful high-altitude winds — and that the planet's auroras run a self-sustaining heat engine.
University of Rochester engineers built a sunlight-powered device with laser-etched metal panels that pull fresh water from the sea while collecting salts and minerals — including lithium — as solids instead of dumping harmful brine.
The mission will explore largely uncharted regions of the Milky Way, potentially revealing more alien worlds than all previous missions combined.
WatchDaraxonrasib, a new RAS-targeting pill, extended median survival to 13.2 months versus 6.7 for chemotherapy in a 500-patient trial — a 60% reduction in the risk of death from one of medicine's deadliest cancers.
A University of Illinois team built working chips with three layers of silicon transistors stacked directly atop one another, achieving near-perfect yields with a low-temperature process that had long stumped the industry.
Salk Institute scientists found that dietary methionine protected animals from severe infection and sepsis not by attacking the invader, but by helping the kidneys flush out the body's own runaway inflammatory molecules.
Compounds fusing vitamin K with retinoic acid were three times better than natural vitamin K at turning stem cells into neurons, pointing to a possible new front against Alzheimer's and Parkinson's.
A Hokkaido University team found that whether a cell with a doubled genome lives or dies depends on how the division error occurred, pointing to a possible vulnerability in recurring tumors.
Researchers used AI to analyze CT scans from tens of thousands of adults and found that people with healthier thymuses lived longer and had substantially lower risks of heart disease, cancer, and death.
Study finds sponges shed measurable plastic particles as they wear down, but water consumption remains the bigger environmental concern.
Great apes organize friendships into inner circles and broader networks, with chimpanzees becoming more selective with age while bonobos maintain egalitarian relationships.
Scientists develop a system using laser-textured metal panels that converts seawater to drinking water while recovering salts as valuable solids, potentially including lithium for batteries.
New research reveals that weight loss through intermittent fasting involves rewiring both gut bacteria and brain regions that control appetite and cravings.
New genetic evidence reveals complex interactions between hunter-gatherers and farmers, with women likely playing crucial roles in spreading agriculture across northwestern Europe thousands of years ago.
Scientists discovered that the planet's northern lights drive powerful atmospheric winds that create electrical currents, solving a decades-old puzzle.
Researchers found that sleep loss damages brain circuits responsible for social memory, but caffeine can restore communication between neurons and reverse memory deficits.
Johns Hopkins research reveals that combining cannabis edibles with alcohol may impair drivers far more than either substance alone, while standard field sobriety tests often fail to detect the impairment.
James Webb Space Telescope reveals that Saturn's aurora creates powerful winds that generate electrical currents, making the planet appear to change rotation rates.
