For decades, microbiologists assumed that macrophages, immune cells that can engulf and poison bacteria and other pathogens, killed microbes by damaging their DNA. A new study from the University of Illinois disproves that.

Scientists engineer living DNA sensors

Early detection of infectious diseases can be key to successful treatment, but we often don't know we are infected until symptoms appear. What if our bodies could detect the presence of an infectious pathogen before the onset ...

Voice-activated system for hands-free, safer DNA handling

Smart voice assistants are a popular way for people to get quick answers or play their favorite music. That same technology could make the laboratory safer for scientists and technicians who handle potentially infectious ...
