Canadian man becomes first human cured with prime gene editing
6+ mon, 1+ week ago (836+ words) Ty Sperle, a 19-year-old from Kelowna, British Columbia, has become the first person cured of a rare inherited immune disorder after doctors used prime gene editing to correct a single DNA error in his own blood-forming cells. His recovery shows…...
Life may have learned to use oxygen long before it filled Earth’s air
7+ mon, 2+ day ago (1001+ words) Oxygen feels like the most ordinary thing in the world now. We breathe it, plants make it, and most animals depend on it. But for most of Earth’s history, oxygen wasn’t a stable part of the atmosphere at all. Scientists…...
Ancient microbes left wrinkles in deep seafloor rocks
7+ mon, 3+ week ago (815+ words) Far below where sunlight can reach, subtle marks in Moroccan stone suggest that life left a record in a place long assumed to be erased by time. The finding matters because it challenges where scientists think fragile traces of early…...
Scientists recover the world's oldest RNA in a well-preserved woolly mammoth
9+ mon, 3+ week ago (755+ words) For years, the story of the woolly mammoth has felt fixed in the past. Ancient bones, frozen tissue, and fragments of DNA help scientists stitch together how these giants lived and died. A new study pushes that story even farther....
Which animal really came first? The debate may finally be settled
9+ mon, 3+ week ago (881+ words) A question has stirred up arguments in biology for years: which creature sits at the very base of the animal family tree? The choice seems simple. It is either the sponge, which has no muscles and no neurons, or the…...
Scientists 'reanimate' a worm that was frozen in Siberian permafrost for over 46,000 years
10+ mon, 3+ week ago (755+ words) In Siberian permafrost, scientists thawed ancient soil and saw tiny nematodes move. These animals “woke up” after an extremely long freeze and resumed life functions in the lab. Their revival raises clear scientific questions and practical ones. How long were…...
Hippos in the Ice Age? DNA reveals a survival story
11+ mon, 1+ day ago (746+ words) Europe during the Ice Age wasn’t always the frozen wasteland we imagine. Between glaciers and tundra, rivers still flowed, and the land breathed in warm intervals. In those moments, something remarkable happened – hippos lived there. A new study published in…...
Biodiversity Cell Atlas project is creating a map of every living thing, cell by cell
11+ mon, 1+ week ago (834+ words) Imagine trying to understand all of life on Earth by looking not just at whole organisms, but by zooming in to see every kind of cell they’re made of – like building a world atlas, but at the microscopic level. A…...
Hemoglobin and other blood molecules found preserved in dinosaur fossils
11+ mon, 4+ week ago (814+ words) Two iconic dinosaurs – Tyrannosaurus rex and Brachylophosaurus canadensis – have yielded a fresh line of evidence that traces of their original biology can survive for tens of millions of years. In new work, researchers at North Carolina State University identified hemoglobin…...
