Explosive crater twins on Mars

(Phys.org) —Dramatic underground explosions, perhaps involving ice, are responsible for the pits inside these two large martian impact craters, imaged by ESA's Mars Express on 4 January.

Optical waveguide connects semiconductor chips

A team of German researchers at KIT directed by Professor Christian Koos has succeeded in developing a novel optical connection between semiconductor chips. "Photonic wire bonding" reaches data transmission rates in the range ...

New research discovers metabolic adaptation to high altitudes

When mammals are cold, they can employ physical changes to stay warm -- such as intense shivering. Like any form of aerobic exercise, though, "shivering thermogenesis" is especially challenging at high altitudes because there ...

World's first tunable broadband RF device emerges

A team of researchers from the Universitat Politecnica de Valencia's iTEAM in Spain has created the first, tunable broadband radio frequency (RF) photonic phase shifter. Because it is based on a single semiconductor element, ...

First stars in universe were not alone

The first stars in the universe were not as solitary as previously thought. In fact, they could have formed alongside numerous companions when the gas disks that surrounded them broke up during formation, giving birth to ...
