The newborn iceberg measures about 278 square miles (720 square kilometers), and was seen by TerraSAR-X, an earth-observing satellite operated by the German Space Agency (DLR). Scientists with NASA's Operation IceBridgefirst discovered a giant crack in the Pine Island Glacier in October 2011, as they were flying over and surveying the sprawling ice sheet.
To call wood frogs hardy would be an understatement. The species (Rana sylvatica) can survive winter temperatures that freeze up to two-thirds of the water in their bodies. They endure this annual popsicle phase with help from cryoprotectants, substances circulating in their blood that lower the freezing point of their body fluids. New research shows that frogs at the northern limits of the species' range are uniquely adapted to freezing.
It transports electrons 10 times faster than silicon, and may soon be replacing it as the go-to material for transistors and computer parts. …
We're talking about "charging iPhones within five seconds" conductivity here. Imagine a world with electric cars that recharge as quickly as filling your tank with gas, or paper-thin foldable plastic phones that recharge the instant you set them down — that's exactly what graphene offers. And then there's the slight matter of its strength. Mix graphene with metals, and it increases their resilience 500-fold.
