SpaceX Successfully Completes 1st Stage 9-Engine Rocket Firing
Space Exploration Technologies (SpaceX) successfully conducted two static firings of the first stage, nine engine cluster for its Falcon 9 launch vehicle. The firings took place at SpaceX's Texas Test Site, a 300-acre structural and propulsion testing facility just outside of Waco, Texas. With completion of these tests, the first stage has now passed both structural and propulsion acceptance testing and will ship to Cape Canaveral in preparation for the first flight of Falcon 9.
Laser microscope aims to uncover alien life
The hunt for signs of extraterrestrial life usually focuses on detecting molecules associated with living organisms. Direct observation through optical imaging would be more conclusive, so Hans Kreuzer and Manfred Jericho at Dalhousie University in Halifax, Nova Scotia, Canada, and their colleagues have taken a different approach. They have built a robust microscope that can be dunked into water to detect any microscopic life forms that may be swimming or floating there.

Why Windows 7's Default UAC Is Insecure
When you run Windows 7 with the default UAC level, a technique using code injection and several components in Windows 7 that can auto-elevate can totally own your system. Microsoft gave several components in Windows 7 special privileges (like notepad.exe and calc.exe) in order to reduce the amount of UAC prompts in Windows. The end result, however, is that these components can be used to bypass UAC completely, and basically get full access to your machine. This works even on the RC.
