New tools to study bioactive lipids

NAEs are bioactive lipid molecules that appear to play roles in energy balance, inflammation, stress responses and addiction. How NAE levels are regulated and their precise contributions to biological processes remain poorly ...

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 ...

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 ...

'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 ...

Asian black bears' smart strategy for seasonal energy balance

A collaboration led by scientists at Tokyo University of Agriculture and Technology (TUAT), Japan, has discovered that daily energy balance of Asian black bears (Ursus thibetanus) exhibited seasonal change with a twin-peak ...

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 ...
