Altering the temperature of a new material could essentially lock in place any of the data stored on it. This suggests it could make a good tamper-resistant component for the next generation of computer hard drives.
A region of star births nestled within the ingredients needed for star formation: clouds of interstellar gas and space dust. The nebula here resides 20,000 light-years away in the constellation Carina. It contains a central cluster of huge, hot stars, called NGC 3603.
This photo shows workers performing maintenance on the target chamber at the National Ignition Facility. The pencil-shaped feature on the right will hold a capsule containing hydrogen while laser beams fire at it from all directions.
Scientists blasted a tiny capsule of hydrogen with laser beams, setting off a reaction that released more energy than in earlier experiments. Still, scientists remain a long way from creating a reaction that releases more energy than it needs to get started.
Everything above absolute zero gives off some heat. Usually objects radiate more heat — or energy — as their temperature climbs. But engineers now have created a material that sometimes appears to cool even as it is warming.
