As we upload more and more videos to the Internet—one hour of new video every second to YouTube alone—experts are finding new ways to mine them. A team led by Igor Curcio of Nokia's Research Center, for example, has developed an algorithm that stitches concertgoers' cellphone footage into a single, synchronized multi-angle film. The concept is relatively simple: the audio track serves as a guide to sync up the footage, and the software chooses the best shots.
Last year, Nature and Science prepared to publish research describing how to mutate H5N1, a deadly bird flu, into more-contagious forms. The papers could help scientists create a treatment should a similar mutation occur in nature. But according to the U.S. government, the papers could also help terrorists create a weapon.
Society must make two big leaps in order to enable truly self-driving cars. The first is technological. Engineers need to improve today’s cars (which can warn a driver that he’s drifting out of his lane) beyond current Google and Darpa prototypes (which maintain the lane on their own) to the point where automobiles can edge forward through a construction zone while their owners sleep inside.
