Researchers at Aalto University, Finland, have created a Bose-Einstein condensate of light coupled with metal electrons, so-called surface plasmon polaritons. Nearly 100 years ago, Albert Einstein and Satyendra Nath Bose ...

Physicists have experimentally demonstrated an information engine—a device that converts information into work—with an efficiency that exceeds the conventional second law of thermodynamics. Instead, the engine's efficiency ...
How can life originate before DNA and genes? One possibility is that there are natural processes that lead to the organisation of simple physical objects such as small microcapsules that undergo rudimentary forms of interaction, ...
