That same technology could make the laboratory safer for scientists and technicians who handle potentially infectious samples. Researchers now report a small, voice-activated device that can extract and pretreat bacterial DNA, helping protect those on the front lines of disease outbreaks. The system could also help scientists with disabilities conduct studies more easily.
