Sherpas have evolved to become superhuman mountain climbers, extremely efficient at producing the energy to power their bodies even when oxygen is scarce, suggests new research published today...
Most of the known volcanic hotspots are linked to plumes of hot rock (red) rising from two spots on the boundary between the metal core and rocky mantle 1,800 miles below Earth's surface.

Coral researchers have for the first time captured the specific behaviour of a coral as it's bleaching.
The team from QUT in Australia used a clever combination...

Populations of many North American songbirds are declining, and in many cases we don't understand why -- for...
Due to its breadth, the Jena experiment proves for the first time that a loss of biodiversity has negative consequences for many individual components and processes in ecosystems.

Leeches, despite the yuck factor, have captured the hearts of two University of California, Berkeley, scientists who are part of a team...
Cosmic rays interacting with the Earth's atmosphere producing ions that helps turn small aerosols into cloud condensation nuclei -- seeds on which liquid water droplets form to make clouds. A proton with energy of 100 GeV interact at the...
