Warming up the world of superconductors

Clusters of aluminum metal atoms become superconductive at surprisingly high temperatures

27-Feb-2015

A superconductor that works at room temperature was long thought impossible, but scientists at USC may have discovered a family of materials that could make it reality. A team led by Vitaly Kresin, professor of physics at USC, found that aluminum "superatoms" - homogenous clusters of atoms - ...

Why a latte is less likely to spill than a coffee

Foam absorbs energy from sloshing liquids, Princeton scientists report in the journal Physics of Fluids

26-Feb-2015

Carrying a full cup of coffee from the kitchen to the dining room can be precarious for a sleepy-eyed caffeine addict who might accidentally send a wave of java sloshing over the rim. But add a bit of foam to the top and the trip becomes easier. Scientists have found that just a few layers of ...
