Science news: space, biology, climate, medicine and the research changing how we live.
A Loma Linda University team traced the 'baby snakes can't control their venom' scare back to 1960s news reports — and showed that adult rattlesnakes actually deliver far more venom and cause worse bites.
In animal models, a glycine-based tripeptide called DT-109 healed the intestinal barrier and rolled back MASH — a dangerous form of fatty liver disease that affects roughly 7% of people worldwide.
Georgia Tech researchers found that low doses of sulfoxaflor — a next-generation insecticide sprayed on corn and soybeans — hit bumblebees' ovaries hardest, raising fresh alarms about the fate of a key pollinator.
A study of a decade of U.S. poison-center data found calls involving GLP-1 drugs jumped from roughly 1,500 a year to more than 8,000 after semaglutide's weight-loss approval — most of them preventable dosing errors.
WashU scientists expected their mRNA vaccine to flop in mice missing the dendritic cells thought to be essential. Instead a related cell stepped in — overturning a core assumption and pointing toward sturdier shots.
Japanese researchers screening microbes from tree frogs, newts and lizards found one strain that erased colorectal tumors entirely — outperforming standard chemotherapy and immunotherapy in the lab.
A Max Planck team says soft lithium 'dendrites' pierce hard ceramic electrolytes like a waterjet cutting through rock. Solving the puzzle could unlock safer, longer-lasting solid-state batteries for phones and EVs.
Cameras captured the pink, blade-snouted 'living fossil' in its natural habitat off Jarvis Island and in the Tonga Trench — the deepest sighting ever of any white shark, extending its known range by 700 meters.
A Warwick–Monash team decoded how bacterial enzymes snap together to churn out variants of drugs like the approved lymphoma treatment romidepsin — a blueprint for engineering better ones.
By redesigning a single piece of hardware with engineered 'metamaterials,' researchers sharpened scans of hard-to-image tissue — without replacing the scanner.
Engineered nanoparticles triggered cancer cells to self-destruct while flipping 'cold' tumors 'hot,' producing complete remissions in mice when paired with immunotherapy.
Refined simulations from a NASA science center suggest the Sun's own magnetic dynamo is what keeps the mysterious tachocline confined to a knife-edge, a key to forecasting solar storms.
Using electric currents and water-based enzymes, a semiconductor chip synthesized 64 DNA sequences in parallel — a cleaner alternative to conventional DNA manufacturing.
Data from the DESI survey point to a lopsided cosmos, with galaxy patterns stretching across billions of light-years that clash with a bedrock assumption behind modern cosmology.
The European space telescope found 31 ancient quasars — two of them shining from when the universe was just 5% of its current age.
The veteran probe swept within six miles of Torifune, snapping close-ups of a snowman-shaped space rock on the first stop of its extended mission.
A new analysis of bones from an Indonesian cave suggests Homo floresiensis neither hunted big game nor controlled fire, deepening the mystery of its origins.
UCLA researchers report that the popular muscle-building compound energizes dendritic cells — the immune system's scouts — potentially making cancer immunotherapy work for far more patients.
Genetic analysis of 132 skeletons in a megalithic tomb near Paris shows the community that built it collapsed — and centuries later, unrelated newcomers from the south were burying their dead in the same graves.
So dim it nearly escaped detection, the newly confirmed dwarf galaxy And 35 is about 12.5 billion years old and offers a rare window into the universe's first generations of stars — and the nature of dark matter.
The galaxy M1149-BSG-z5 already had a central bar of stars less than 1.2 billion years after the Big Bang — a structure astronomers assumed couldn't exist so early, and one that rewrites the timeline for how galaxies grow up.
By rebuilding an ancient version of nitrogenase, researchers reopened a window on how microbes fed themselves before oxygen — and handed astrobiologists a chemical fingerprint to hunt for life beyond Earth.
A new proposal argues that rock and soil returned from Mars and beyond should be screened at a robotic facility on the Moon first — casting the lunar surface as humanity's first line of biological defense.
Using 3D live imaging of follicles kept alive in the lab, researchers found that coordinated cell movements act like a tiny motor, tugging the hair shaft upward — a discovery that could reshape baldness treatments.
When levels of a gene-regulating factor called GATA6 fall, colorectal cancer cells revert to a primitive, fetal-like state that can invade the bloodstream and seed tumors in the liver, a Weill Cornell and MIT study finds.
To celebrate the James Webb Space Telescope's fourth science anniversary, NASA unveiled a new view of Centaurus A, peering through the dust that had long hidden the galaxy's violent heart.
A new study finds that measuring apoB — a protein tag on every harmful cholesterol particle — guides treatment better than the standard LDL test, and does it cost-effectively.
In Israel, scientists documented swirling rings of more than 5,000 woodlice circling endlessly under artificial light — a collective behavior never before seen in the species.
A UC Berkeley team traced how non-REM sleep unleashes growth hormone — and found the hormone loops back to nudge the brain awake, a self-balancing system tied to muscle, fat and memory.
The University of Minnesota's 'SpudCell,' assembled entirely from non-living chemical parts, completes a full life cycle — a milestone biologists have chased for decades.
