Ridding tap water of bacteria with chemicals is a common practice in America, but one Biodesign Institute researcher is finding benefits to putting the bacteria back in.
The use of microbial agents to decontaminate tap water has long been the standard in Europe, but an American bias against b... Read More
A less than 30-second movie from the 1950s shows a white blood cell (neutrophil) pursuing the Staphylococcus aureus bacteria on blood film.
The 16-mm moving image was captured by late David Rogers, who at the time was a professor at Vanderbilt University and went on to co-chair the National C... Read More
