Just seven photons in a mirrored trap formed a Bose-Einstein condensate, one of the more exotic particle states — and one usually reserved for matter.
The strange radio bursts usually circle the Earth like electromagnetic ghosts, but scientists have now created and studied their shapes in a plasma chamber on Earth.
The technology could improve future precision light sources. But right now the biggest surprise is how many holes there are in a laser figure-eight.
If you draw lightning bolts like crooked zigzags, then you're doing it wrong — but at least you're in good company. Artists have drawn lightning incorrectly for hundreds of years, a new study finds.
