Does Antimatter Fall Up or Down?
Theory and observations support the view that antimatter experiences gravity just as ordinary matter does, but the evidence so far has been indirect. Indeed, some theorists speculate that antimatter is antigravitational, that it may fall “up” instead of “down.” Led by Berkeley Lab physicists, the ALPHA Collaboration at CERN has made direct measurements of the gravitational mass of atoms of antihydrogen, testing which way they fall and in what direction.

BELLA Laser Achieves World Record Power at One Pulse Per Second
The laser system for BELLA, the Berkeley Lab Laser Accelerator, recently delivered a petawatt of power – a quadrillion watts – in a pulse just 40 femtoseconds long – a quadrillionth of a second -- at a rate of one pulse per second. No other laser system has achieved this peak power at this rapid pulse rate. BELLA’s laser should soon be driving electron beams to 10-billion-electron-volt energies in an accelerator just one meter long.
