Zoom in on a soap bubble just before it bursts and brilliant, complex patterns emerge. Shimmery rainbows appear in thicker portions of the soap film, while clusters of dark spots appear in the thinnest regions. Over about a minute, those spots grow and merge. This effect,...
A single-sided sonic tractor beam that can levitate objects without the need for complex phase-shifting electronics has been developed by researchers in the U.K. Instead the device uses an acoustic lens, which can be made with a set of 3-D-printed cells or a shaped surface...
Dark matter has just suffered another blow. Only one experiment claims to have seen signs of the mysterious stuff, and now the massive XENON100 experiment has failed to find any evidence for that signal. This may put the controversial signal...
The LIGO experiment hunts for gravitational waves that are different from those sought by BICEP2. Although both types are elusive, they differ in age and strength—and come from very different places.
What would happen if you stuck your body inside a particle accelerator? The scenario seems like the start of a bad Marvel comic, but it happens to shed light on our intuitions about radiation, the vulnerability of the human body, and the very nature of matter.
Astronomers have traced a series of brief, enigmatic bursts of radio waves to a galaxy far, far away and indeed a long time ago — some three billion years or so. But as much as you might be hoping or dreading it to be true, this is probably not E.T.
