A pocket-sized device that runs on two AA batteries and copies DNA as accurately as expensive lab equipment has been developed by researchers in the US. The device has no moving parts and costs just $10 to make. It runs polymerase chain reactions (PCRs), to generate billions of identical copies of a DNA strand, in [...]

Electromagnetic “wormhole” results from turning invisible sphere inside out. Viewed straight on, light simply zips down the tube. But from the side, light would appear to come out of nowhere, as though sent on a detour to another dimension and back.read more | digg story
