Shock grows motile cells (IMAGE) University of California - San Diego Caption UC San Diego scientists developed a new technology that specifically targets one type of cell among genetically identical bacteria that live in the same microenvironment. They discovered that a second-long shock emitted by an electrode (dark circle in the center), preferentially causes growth of (orange) motile cells, rather than (blue) matrix-producing cells, thereby changing the ratio of cell types in the community.
