When a ballerina pirouettes, twirling a full revolution, she looks just as she did when she started. But for electrons and other subatomic particles, which follow the rules of quantum theory, that’s not necessarily so. When an electron moves around a closed path, ending up where it began, its physical state may or may not […]

Scientists have created the world’s thinnest hologram that can be seen without 3D goggles and may be integrated into everyday electronics such as smartphones, computers, and TVs. Interactive 3D holograms are a staple of science fiction – from Star Wars to Avatar – but the challenge for scientists trying to turn them into reality is […]

It’s rare for animals to engage in what’s called “coordinated hunting” — but that’s exactly what Cuban boa snakes do, according to new research published in the journal Animal Behavior and Cognition. Coordinating hunting is distinct from hunting in groups, which is common across the animal kingdom. It takes place when animals relate in both […]

Lighter-toned bedrock that surrounds fractures and comprises high concentrations of silica—called “halos”—has been found in Gale crater on Mars, indicating that the planet had liquid water much longer than previously believed. The new finding is reported in a paper published today in Geophysical Research Letters, a journal of the American Geophysical Union. “The concentration of…
