Model suggests it’s raining rocks on exoplanet
WASHINGTON-ST. LOUIS (US)—An exoplanet discovered last February by the COROT space telescope is close enough to its star that its “day-face” is hot enough to melt rock. Theoretical models suggest the planet has a gaseous-rock atmosphere and boiling oceans on its surface. (more…)

Dancing with high-temp superconductors
A computer-generated representation of the data obtained by scanning a cuprate superconductor in sub-atomic steps. Each cross represents a “Cooper pair” of electrons. At a temperature below 37K (bottom sheet) the pairs are in an orderly arrangement and current can flow without resistance. At a higher temperature the Cooper pairs are still present, but no longer orderly. (Credit: Jhinhwan Lee/Davis Group/Cornell University)

Drilling deep to take Earth’s temperature
“We now also know that, although the beginning of ice ages (in the Northern Hemisphere) is linked to greenhouse gases, the change in intensity is related to how ice sheets grow and decay,” says Sindia Sosdian (left in helmet), seen above working with core samples on an earlier expedition.

Amphibians don’t cozy up to warmer climes
“We could see changes to ecosystem structure and stability if cold-blooded species change their life histories to accommodate warmer temperatures but warm-blooded species do not,” says researcher Santiago Salinas.

Putting on the squeeze to ‘freeze’ water
PRINCETON (US)—Think there’s only one way to freeze water? Think again. Researchers may be able to “freeze” water into a solid, not by cooling it, but by confining it to narrow spaces less than one-millionth of a millimeter wide. (more…)
