Small but perfectly-formed, as they say, the smallest synthetic motor ever made – an electric rotor on an axle 2,000 times shorter than the width of a human hair – has been built by scientists at the University of California’s Lawrence Berkeley National Laboratory.
Its inventors believe this micro-scale motor could enable breakthroughs in optical [...]

Even if the only evidence forensic analysts can pull from a crime scene is a fingerprint smudged beyond recognition, a new technique developed by Canadian scientists soon could harvest enough DNA from the print to produce a genetic identity.
The novel system can extract DNA in only 15 minutes, even if a print has been stored [...]
