Hidden ingredient in Ozempic and Wegovy tablets raises new gut health questions
Scientists are taking a closer look at the pill forms of Wegovy and Ozempic. In an animal study, the ingredient SNAC, which helps semaglutide survive …
How the body really ages: 7 million cells mapped across 21 organs
Scientists have built a massive cellular atlas showing how aging reshapes the body across 21 organs. Studying nearly 7 million cells, they found that aging …
A major climate hope in Antarctica just melted away
A popular climate theory suggested that melting Antarctic glaciers would release iron into the ocean, sparking algae blooms that pull carbon dioxide from the air. …
The first animals on Earth had no skeletons and that changes everything
Sponges may be ancient, but their timeline has been murky. New research suggests the earliest sponges were soft and skeleton-free, explaining why their fossils don’t …
Textbooks challenged by new discovery about how cells divide
Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell …
Scientists discover a bacterial kill switch and it could change the fight …
Drug-resistant bacteria are becoming harder to treat, pushing scientists to look for new antibiotic targets. Researchers have now discovered that several unrelated viruses disable a …
Your morning coffee could one day help fight cancer

MIT study finds Earth’s first animals were likely ancient sea sponges
Scientists at MIT have found compelling chemical evidence that Earth’s earliest animals were likely ancient sea sponges. Hidden inside rocks over 541 million years old …
A lost moon may have created Titan and Saturn’s rings
Saturn’s largest moon, Titan, may have been born in a colossal cosmic crash. New research suggests Titan formed when two older moons slammed together hundreds …
Stunning 3D maps reveal DNA is structured before life “switches on”
For decades, scientists believed a fertilized egg’s DNA began as a shapeless mass, only organizing itself once the embryo switched on its genes. But new …
American Heart Association warns 60% of US women will have cardiovascular disease …
Heart disease is on track to tighten its grip on American women. New projections from the American Heart Association warn that over the next 25 …
Scientists compared dinosaurs to mammals for decades but missed this key difference
Baby dinosaurs weren’t coddled like lion cubs or elephant calves—they were more like prehistoric latchkey kids. New research suggests that young dinosaurs quickly struck out …
New engine uses the freezing cold of space to generate power at …
Engineers at UC Davis have built a remarkable device that creates power at night by tapping into something we rarely think about: the vast cold …
Green hydrogen has a hidden problem and scientists may have fixed it
Green hydrogen could be a game-changer for the clean energy transition—but right now, it’s too expensive and still relies on harmful “forever chemicals.” A new …
Popular brain supplement linked to shorter lifespan in men
A massive study of more than 270,000 people has uncovered a surprising link between a common amino acid and how long men live. Researchers found …
Antarctica just saw the fastest glacier collapse ever recorded
Antarctica’s Hektoria Glacier stunned scientists by retreating eight kilometers in just two months, with nearly half of it collapsing in record time. The rapid breakup …
Researchers unlock hidden dimensions inside a single photon
