Clever feedback system regulates immune responses

A newly discovered feedback mechanism in the body is responsible for keeping immune responses from getting out of hand. It works at the level of certain genes, linking the inactivation of those genes to the progress made ...

Measuring the smallest vibration

EPFL scientists have used feedback to cool the motion of a micron-sized glass string to near absolute zero. This required building a sensor capable of resolving the smallest vibration allowed by quantum mechanics.

El Nino cycle has a big effect on a major greenhouse gas

Nitrous oxide is commonly associated with laughing gas—the pleasantly benign vapor that puts patients at ease in the dentist's chair. But outside the dentist's office, the gas plays a serious role in the planet's warming ...

Perfect skin: More touchy-feely robots

Robots could become a lot more 'sensitive' thanks to new artificial skins and sensor technologies developed by European scientists. Leading to better robotic platforms that could one day be used in industry, hospitals and ...

Climate change: More carbon dioxide leads to fewer clouds

(Phys.org)—The warmer the air, the more water can evaporate: a simple relationship familiar to us from everyday life. Researchers from Germany and the Netherlands have now established that this is not always the case: although ...
