About The Cover

Online Cover This week features a Research Article reporting that the matrix protein TasA maintains a subpopulation of motile cells within Bacillus subtilis biofilms. The image shows matrix-producing cells (blue) and motile cells (yellow) within a biofilm of Bacillus subtilis lacking TasA. In wild-type colonies, a subpopulation of cells is motile, but this subpopulation is reduced in colonies of tasA deletion mutants. [Image: Steinberg et al./Science Signaling]
