Researchers are taking thermodynamics to a whole new level: the microscopic level. The science of heat and energy exchange underpins most of our modern life, as well as the fate of the universe.

Researchers demonstrated a new type of optical manipulation: using laser light to pull a macroscopic object. The technology has potential for applications in the continued explorations of Mars.

Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect—a long-predicted phenomenon at the crossroads of relativity and quantum theory. Their ...

String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a patch of space, the theory says, and you won’t see a menagerie of ...
