Figure shows the likely habitats of vibrio bacteria populations mapped by MIT researchers onto a phylogenetic tree for all strains found in the samples taken from the Atlantic Ocean near Plum Island, Mass. Dot colors indicate the size of the bacteria (the largest attach to zooplankton, next size attaches to large organic particles, then small organic particles, and finally the smallest are free-fl...

Human mammary epithelial cells that undergo an epithelial-to-mesenchymal transition (EMT) in culture may grow in suspension into structures called mammospheres--a trait they share with mammary epithelial stem cells. Here, the yellow cells present surface proteins indicating that they can develop into more than one type of mammary cell.

Philip Lessard, Kazuhiko Kurosawa and Anthony Sinskey display a new type of antibiotic they produced by pitting two strains of bacteria against one another. Lessard, a research scientist, and postdoc Kurosawa work in the MIT lab of Sinskey, a professor of microbiology and health sciences and technology.
