Quantum heat pump: A new measuring tool for physicists

Physicists from TU Delft, ETH Zürich and the University of Tübingen have built a quantum scale heat pump made from particles of light. This device brings scientists closer to the quantum limit of measuring radio frequency ...

Satellite galaxies of the Milky Way help test dark matter theory

A research team led by physicists at the University of California, Riverside, reports tiny satellite galaxies of the Milky Way can be used to test fundamental properties of "dark matter"—nonluminous material thought to ...
