Join our expert "TechKnow" contributors Phil Torres, Kyle Hill, Lindsay Moran and Shini Somara as they explore new technology and its impact on our lives. Lindsay tests a new gun with high-tech safety features. Kyle explores early earthquake detection systems already used in other countries. And Phil looks at how cars can communicate—with each other—for safer driving.
