Researchers at the Georgia Institute of Technology have developed a prototype wireless sensor capable of detecting trace amounts of a key ingredient found in many explosives. The device employs carbon nanotubes printed on paper or paper-like material by using standard inkjet technology, and it could be deployed in large numbers to alert authorities to the… »

A group of researchers from the Colorado State University (CSU) managed to make a computer-designed detection trait work in a plant by rewiring its natural signaling process. It enables the plant to turn from green to white when chemicals are detected in the air around it or in the soil it is planted in. The… »
