The Advanced Research Projects Agency for Energy (ARPA–E) works on a three-year cycle: Funded projects have three years to prove worthy--or not. Program directors who help fund projects such as Plants Engineered to Replace Petroleum ( PETRO ) or Batteries for Electrical Energy Storage in Transportation ( BEEST ) have three years to steer the research. And, after three years at the helm as the founding director of ARPA–E, mechanical engineer Arun Majumdar has announced that he will be stepping down in June.

Occupy Wall Street protesters, however, are dealing with a special challenge: Online marketers and analytics firms tracing the minutiae of their lives--including their email contacts and physical location--and possibly passing the information on to law enforcement.
