Unmanned Aerial Vehicles Mark Robotic First For British Antarctic Survey

Scientists have completed the first ever series of flights by autonomous unmanned aerial vehicles in Antarctica. This is the first time that unpiloted UAVs have been used in the Antarctic and the successful flights open up a major new technique for gathering scientific data in the harshest and remotest environment on Earth.

Fake Diamonds Help Jet Engines Take The Heat

Engineers are developing a technology to coat jet engine turbine blades with zirconium dioxide -- commonly called zirconia, the stuff of synthetic diamonds -- to combat high-temperature corrosion. The zirconia chemically converts sand and other corrosive particles that build up on the blade into a new, protective outer coating. In effect, the surface of the engine blade constantly renews itself.

Camera Brings Vast Improvement For Surveillance

Researchers have developed a wide-angle camera that will be able to provide security forces with the ability to monitor large areas through high-resolution images taken from a satellite or an airborne craft. If you point a large number of lenses toward a common point, and then make a small correction on each of the lenses, you provide a camera with capabilities that far surpass existing technologies.
