Superman's Memory Crystals May Become Computer Reality
Researchers at Southampton University used lasers to rearrange the atoms in pieces of glass, turning it into new type of computer memory. They claim the glass memory is far more stable and resilient than current types of hard-drive memory, which have a limited lifespan of a couple of decades and are vulnerable to damage from high temperatures and moisture. The glass memory can withstand temperatures of up to 1,800 degrees F, is unaffected by water and can last for thousands of years without losing information. Information can be written, wiped and rewritten into the molecular structure of the glass using a laser, the scientists claim. The process changes the way light travels through the glass, creating whirlpools of polarised light that can then be read in much the same way as data in optical fibres.
