"Each year, Technology Review chooses 10 emerging technologies with the potential to change lives around the world. Some of this year's choices, such as paper-based medical tests and intelligent software that acts as a personal assistant, could reach the market within a year. Others, like biological machines and nanopiezotronics, could take longer but promise fundamental shifts in fields from computing to medicine, communications to manufacturing. The list includes technologies miniature and massive--from fast, cheap, capacious computer memory to batteries that can store enough energy to power a city. All are technologies that we bet will make a huge impact in the years ahead".
