The six tech policy problems Congress failed to fix this year August isn't the top time of year for thinking about tech policy.

Yahoo joins Google effort to encrypt email Yahoo said Thursday it will join an effort by rival Google to create an encrypted email system by next year that could make it mathematically impossible to hand over users' messages to a court. If they're successful, it would mark a big step in bringing encrypted messaging -- long the province of privacy hawks and conspiracy theorists -- to a consumer-friendly service. The WSJ (also, Secure websites to get Google search boost)

NASA's 'falling saucer' test vehicle footage released NASA's Martian robots have used the planet's thin atmosphere to their advantage while landing, slowing down through a combination of aerobraking and parachutes.
