What makes penguin feathers ice-proof

The range of Humboldt penguins extends from coastal Peru to the tip of southern Chile. Some of these areas can get frigid, and the water the birds swim in is part of a cold ocean current that sweeps up the coast from the Antarctic.

Quantum phase transition underpins superconductivity in copper oxides: CIFAR researchers in Canada and France unveil key organizing principle of high-temperature superconductivity

Settling a 20-year debate in the field, they found that a mysterious quantum phase transition associated with the termination of a regime called the "pseudogap" causes a sharp drop in the number of conducting electrons available to pair up for...
