Science news: space, biology, climate, medicine and the research changing how we live.
A Leiden University team found the rock-cut burial of a New Kingdom dignitary named Paser in the Theban necropolis, complete with a courtyard, chapel and underground chambers.
University of Illinois researchers found that decision signals reach even the brain's primary sensory areas through rapid top-down feedback, overturning the idea that perception simply flows forward.
At a cave in southern Türkiye, both human groups selectively gathered marine shells with no food value for more than 20,000 years — a sign, researchers say, of shared symbolic behavior.
The world's longest-running soil warming study reports that carbon once thought locked away for good is breaking down as temperatures rise — a feedback that could amplify future warming.
The car-sized rover crossed the 42.195-kilometer mark on its 1,890th Martian day while exploring ancient terrain west of Jezero Crater, shattering the pace set by its predecessor Opportunity.
University of Bristol researchers found that moderate aerobic training reshapes the nerve clusters controlling the heart in a striking left-right pattern, a discovery that could refine treatments for dangerous heart rhythms.
The retina's visual pathways don't work in isolation after all: researchers discovered an electrical network, coordinated by a newly identified 'commander' cell, that lets separate channels share signals to catch the faintest details.
In a six-week experiment, healthy adults who trimmed their sleep by about an hour and 20 minutes gained weight and moved less — a warning about the metabolic cost of the kind of mild sleep loss millions experience.
A new study suggests Europe's most active volcano is fed by static pockets of magma some 80 kilometers down, defying the three classic ways volcanoes are thought to form.
Some 252 million years ago, roughly 96% of marine species vanished. A new study pinpoints which animals' metabolisms could not survive warmer, oxygen-starved seas.
An underwater eruption near Papua New Guinea has been spewing steam and staining the ocean since May, and scientists are waiting to see whether a new island will be born.
Erythrulose, a four-carbon sugar found in raspberries, was spotted in a cloud near the galaxy's center — and may have rained down on the early Earth by the millions of tons.
A duck-billed Edmontosaurus skull from Montana still carries the broken tooth of its attacker — rare, direct evidence of how the tyrant king hunted.
In a randomized study of adults living with HIV, semaglutide cut the pace of biological aging by 9%, the first clinical hint the blockbuster drug may touch aging itself.
USC researchers who surveyed 187 lung cancer patients under 50 — most of whom never smoked — found they ate more fruits, vegetables and whole grains than average, raising questions about pesticide residue.
Scientists report that Porphyromonas gingivalis, a bacterium behind gum disease, can lodge in the aortic valve and drive the calcium buildup that causes a common and deadly heart condition.
Oaks continue absorbing carbon dioxide for months after their wood stops adding rings — a finding that could reshape how climate models treat forests.
Signals tied to decision-making showed up in a region long dismissed as a simple sensory relay, suggesting the brain weighs choices from the very first moments a signal arrives — and hinting at a blueprint for more efficient artificial intelligence.
Methane from spacecraft engines can 'hop' across the lunar surface and pile up in the very frozen craters scientists hope will preserve pristine clues to life's origins, researchers say.
In preclinical experiments, the widely used medication telmisartan sharply boosted the tumor-killing power of the targeted drug olaparib and rallied the immune system to join the attack.
Two fast-breeding mantis species from Asia have been formally declared invasive as they push northward across the continent, preying on pollinators, small vertebrates and even native mantises.
A massive, chemically mature spiral with a 14,700-light-year central bar existed just over a billion years after the Big Bang — a structure astronomers thought could not form so early.
In rats, a fiber-rich diet kept a beneficial tapeworm healthy and anti-inflammatory; strip the fiber away and the worm slipped into a hibernation-like state, wiping out its benefits.
Using lab-grown human retinas, Johns Hopkins scientists found the fovea gains its high-resolution color vision not by shuffling cells around but by converting them — a finding that rewrites a textbook belief.
Georgetown researchers used fMRI and EEG to show that intense practice pushes a learned task out of the bottlenecked prefrontal cortex, freeing the brain to genuinely do two things at once.
A rare goose unearthed from an ancient lakebed in Central Otago suggests the country's colossal 18-kilogram geese descended from far more recent arrivals than scientists long assumed.
A study in mice finds that tau — infamous for the tangles it forms in dementia — is essential during a brief window for turning fresh experiences into durable memories, reframing how scientists think about the protein.
Indian researchers found 32 color patterns in a single new species, Theridion himalayana, whose grinning markings evolved entirely separately from its celebrated Pacific look-alike.
Amsterdam UMC scientists scanned women across pregnancies and found a second one reshapes attention and movement networks, and that bigger changes tracked with fewer depression symptoms.
A Science Advances study found up to a third of an oak's yearly carbon capture happens after its wood is done growing, decoupling two processes scientists long assumed moved together.
