New study overturns orthodoxy on how macrophages kill bacteria
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 ...
Simple device can ensure food gets to the store bacteria free
A Purdue University researcher has found a way to eliminate bacteria in packaged foods such as spinach and tomatoes, a process that could eliminate worries concerning some food-borne illnesses.
Method reveals what bacteria sense in their surroundings
