Phys.org / New species of ancient mollusk found in South Korean waters

Scientists have discovered a new species of chiton, an ancient marine mollusk that has remained virtually unchanged for the last 300 million years. Chitons have an elongated oval shape with a shell composed of eight interlocking ...

Phys.org / New LVK catalog adds 128 gravitational-wave candidates, more than doubling detections

When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves, that reverberate across space and time, over hundreds of millions and even billions of years. ...

Phys.org / Microbial ancestor of complex life was more sophisticated than previously thought, studies suggest

Our single-celled ancestor lived in a world without plants, animals or oxygen-rich oceans. Yet, this seemingly simple microorganism took the first steps toward complex life. From this ancestor emerged all multicellular (complex) ...

Phys.org / Why woodpeckers rarely get rattled: Skulls built to control rotation, not cushion blows

Woodpeckers are well known for striking tree trunks with remarkable force and precision. These birds deliver thousands of high-speed impacts per day, generating mechanical loads that would destabilize the skulls of most other ...
