A new JSTAT study shows how to compute the minimum energy cells use to sustain certain metabolic pathways while suppressing ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

Researchers led by Rice University's Guido Pagano used a specialized quantum device to simulate a vibrating molecule and ...

There are “costs of life” that mechanical physics cannot calculate. A clear example is the energy required to keep specific biochemical processes active — such as those that make up ...

Almost exactly 200 years ago, French physicist Sadi Carnot determined the maximum efficiency of heat engines. The Carnot ...

Physicists from Trinity College Dublin believe new insights into the behaviour of light may offer a new means of solving one ...

A new study enhances hydrogen molecule predictions, achieving unprecedented precision in testing fundamental physics and ...

At first glance, physics and food science appear to belong to different worlds. Physics is often seen as abstract, mathematical and distant from daily life, while food science feels immediate, ...
