| Phase change memory-based 'Moneta' system points to the future of computer storage Posted: 02 Jun 2011 12:30 PM PDT Researchers are about to demonstrate a first-of-its kind, phase-change memory solid state storage device provides performance thousands of times faster than a conventional hard drive and up to seven times faster than current state-of-the-art solid-state drives.  |
| Researchers build largest biochemical circuit out of small synthetic DNA molecules Posted: 02 Jun 2011 12:30 PM PDT In many ways, life is like a computer. An organism's genome is the software that tells the cellular and molecular machinery -- the hardware -- what to do. But instead of electronic circuitry, life relies on biochemical circuitry -- complex networks of reactions and pathways that enable organisms to function. Now, researchers have built the most complex biochemical circuit ever created from scratch.  |
| Quantum physics first: Physicists measure without distorting Posted: 02 Jun 2011 11:31 AM PDT Quantum mechanics is famous for saying that a tree falling in a forest when there's no one there doesn't make a sound. Quantum mechanics also says that if anyone is listening, it interferes with and changes the tree. And so the famous paradox: how can we know reality if we cannot measure it without distorting it? An international team of researchers has found a way to do just that by applying a modern measurement technique to the historic two-slit interferometer experiment in which a beam of light shone through two slits results in an interference pattern on a screen behind.  |
| Microscopic worms could help open up travel into deep space Posted: 02 Jun 2011 06:54 AM PDT A space flight by millions of microscopic worms could help us overcome the numerous threats posed to human health by space travel. The Caenorhabditis elegans (C. elegans) have also given experts an insight into how to block muscle degradation in the sick and elderly.  |
| Posted: 02 Jun 2011 06:18 AM PDT Researchers have developed a method for creating single-crystal arrays of the material graphene, an advance that opens the possibility of a replacement for silicon in high-performance computers and electronics. Graphene is a one-atom-thick layer of carbon that was first fabricated in 2004. Single-crystal arrays of the material could be used to create a new class of high-speed transistors and integrated circuits that use less energy than silicon electronics because graphene conducts electricity with little resistance or heat generation.  |
