Defying gravity with the Brazil nut effect

Physicists from the University of Utrecht and the Faculty of Physics at the University of Warsaw have observed—for the first time experimentally—the Brazil nut effect in a mixture of charged colloidal particles.

Physicists confirm effective wave growth theory in space

A team from Nagoya University in Japan has observed, for the first time, the energy transferring from resonant electrons to whistler-mode waves in space. Their findings offer direct evidence of previously theorized efficient ...
