science and technology

A project underway aims to develop a variety of nanomaterials that will aid threat detection and neutralization, enhance human performance, provide real-time automated medical treatment and reduce logistical footprint on the battlefield. The materials will be integrated into uniforms to protect soldiers and increase survivability.

Exciting a land mine may not sound like a good idea, but developers of the Seismic Landmine Detection System are doing just that. A group of researchers from the Georgia Tech Research Institute in Atlanta, Georgia, has developed a land mine detection system that sends seismic waves through a minefield, slightly moving the earth and items buried beneath. A noncontacting radar sensor measures the ground displacement to identify and locate plastic anti-personnel or antitank mines.

A new approach to guided munitions may empower small warheads with the same targeting precision employed by larger glide bombs and missiles. The technology takes a low-cost approach to guidance that could improve precision for artillery rounds, mortar shells and grenades for as little as $100 per warhead. Mass-production ultimately could open up the technology for bullets at an even lower cost.
