When most people hear the words "fuel cell," they think of eco-friendly, hydrogen-powered cars that emit nothing more than water.

The U.S. Department of Energy's (DOE) recent decisions about how to fund fuel cell research, he says, are putting the country at risk of falling behind in the development and implementation of the most efficient means of converting fuel to electricity.

A squad of UK-based researchers claims to have urbanized a thermal lie-detection camera that can automatically spot a burning conscience. The system could be used during customs interrogates and at passport control to check whether people entering the country are giving a true account of themselves.

The thermal-imaging camera captures variations in facial temperature in response to questioning. When someone is making something up on the spot, brain activity usually changes and you can detect this through the thermal camera.
