By using common materials found pretty much anywhere there is dirt, a team of researchers has developed a new thermoelectric material. This is important, they said, because the vast majority of heat that is generated from, for example, a car engine, is lost through the tail pipe. It's the thermoelectric material's job to take that heat and turn it into something useful, like electricity.

Scientists have found a way to boost current industry capabilities when it comes to reducing the number of E. coli 0157:H7 cells that may live undetected on spinach leaves. By combining continuous ultrasound treatment with chlorine washing, they can reduce the total number of foodborne pathogenic bacteria by over 99.99 percent.

A "sonar vision" system that enables people who are blind from birth to perceive the shape of a face, a house or even words and letters, is now being developed. Using this device, the researchers have shown that, in people that are blind from birth, the areas of the cerebral cortex normally devoted to reading become activated in response to stimulation.
