IT is well known that when positrons are annihilated, -rays with quantum energy of about 500 ekv. are emitted. This seems to prove that annihilation occurs with a loosely bound electron as a ...

When we see "polar bears on melting glaciers, we have an empathetic response," said Susan Clayton, a conservation psychologist at the College of Wooster. “It’s one way to take this big ...

it’s a rare and incredibly important observation that could potentially inform conservation strategies. Scientists have captured rare footage of female polar bears emerging from maternal dens ...

The symmetry of moving around in a circle amounts to the law of conservation of angular momentum. Symmetry in time – that is, physics remaining the same when translated forwards or backwards in ...
