Bacteria and other microbes love living in slimy communities that cling to riverbed rocks and swimming pool walls, contaminate factory equipment and medical implants, and sometimes coat the teeth as plaque. When such microbe gatherings stick to a hard surface, they’re called biofilms. They're al... Read More
Mathematics and Biology have a long history together. It goes back to early studies on epidemiology (such as John Snow‘s on cholera and the Broad Street pump), and includes Ross’s quantitative studies that show how malaria can be controlled by careful analysis of data. And, of course, there are ... Read More
