University of Otago physicists have used a small glass bulb containing an atomic vapor to demonstrate a new form of antenna for radio waves. The bulb was "wired up" with laser beams and could therefore be placed far from ...

This week, researchers proved empirically that life isn't fair. Also, you'll notice that, in a superhuman display of restraint, I managed to write a paragraph about the simulated universe hypothesis without once referencing ...
Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original quality of the beam, ...
