Mar. 3, 2026 A famously resilient bacterium may be tough enough to survive one of the most violent events imaginable on Mars. In laboratory experiments designed to mimic the crushing shock of a massive asteroid ...
Mar. 3, 2026 Earth’s vertebrate diversity may be far richer than anyone realized. A sweeping analysis of more than 300 studies suggests that for every known fish, bird, reptile, amphibian, or mammal species, ...
Mar. 3, 2026 Tiny, tooth-sized fossils have just reshaped the story of our deepest ancestry. Paleontologists have discovered the southernmost remains ever found of Purgatorius—the earliest-known relative of all ...
Mar. 1, 2026 Jupiter’s icy moons may have been seeded with the chemical ingredients for life from the very beginning. An international team of scientists modeled how complex organic molecules—essential ...
Feb. 28, 2026 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 appear until much later. By ...
Feb. 28, 2026 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 in two. Studying ...
Feb. 28, 2026 Scientists at UC Berkeley have discovered a microbe that bends one of biology’s most sacred rules. Instead of treating a specific three-letter DNA ...
Feb. 27, 2026 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 are rare molecular ...
Feb. 27, 2026 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 research reveals that the genome is already ...
Feb. 27, 2026 Baby dinosaurs weren’t coddled like lion cubs or elephant calves—they were more like prehistoric latchkey kids. New research suggests that young ...
