Cold air rises—what that means for Earth's climate

Conventional knowledge has it that warm air rises while cold air sinks. But a study from the University of California, Davis, found that in the tropical atmosphere, cold air rises due to an overlooked effect—the lightness ...

Food system sustainability requires lower energy use

Modern sustainability practices often encourage resource and energy efficiencies across separate sectors, such as food production or biofuels, but this siloed approach could actually lead to ongoing environmental decay, according ...

'Melting rock' models predict mechanical origins of earthquakes

Engineers at Duke University have devised a model that can predict the early mechanical behaviors and origins of an earthquake in multiple types of rock. The model provides new insights into unobservable phenomena that take ...

Gaining insight into the energy balance of earthquakes

Researchers at EPFL's Computational Solid Mechanics Laboratory and the Weizmann Institute of Science have modeled the onset of slip between two bodies in frictional contact. Their work, a major step forward in the study of ...
