One of the most bizarre-looking fossils ever found - a worm-like creature with legs, spikes and a head difficult to distinguish from its tail – has found its place in the evolutionary Tree of Life, definitively ...
Urination duration: Study finds most mammals need about 21 seconds
Headed to the bathroom? If you think you might have to "pee like a race horse," join the club - so does everyone else. Scientists who watched dozens of different mammals from rats to elephants relieve themselves ...
Ferroelectric switching seen in biological tissues
Measurements taken at the molecular scale have for the first time confirmed a key property that could improve our knowledge of how the heart and lungs function.
Not too fast, not too slow: Researchers untangle energetics of extinct dinosaurs
(Phys.org) —Dinosaurs dominated the landscape for more than 100 million years, but all that remains today are bones. This has made it difficult to solve a long-standing and contentious puzzle: were dinosaurs ...
Scientists trace nanoparticles from plants to caterpillars

The story of a bizarre deep-sea bone worm takes an unexpected twist
The saga of the Osedax "bone-eating" worms began 12 years ago, with the first discovery of these deep-sea creatures that feast on the bones of dead animals. The Osedax story grew even stranger when research ...
Worms' mental GPS helps them find food
You've misplaced your cell phone. You start by scanning where you remember leaving it: on your bureau. You check and double-check the bureau before expanding your search around and below the bureau. Eventually, ...
