Now, scientists at MIT have created an experimental set-up that recreates the quantum Hall effect, but uses ultracold cloud ...

We’ve all learned in school that the speed of light in a vacuum is a constant universal limit, an impassable cosmic boundary.

The positive and negative ions attract each other and form the ionic compound sodium chloride. One calcium and two chlorine atoms are near each other. An electron from each atom feels the attraction ...

The study finds that a part of the signal could be arising from a thin veneer of sodium atoms weakly bound to the lunar grains. These sodium atoms can be nudged out of the surface by solar wind or ...
