Genetically Encoded Mouse Cells Controlled By Light

UCSF researchers have genetically encoded mouse cells to respond to light, creating cells that can be trained to follow a light beam or stop on command like **microscopic robots**. This is the first time researchers have been able to import a light controlled "on-off switch" from plants into a mammalian cell to instantly control a variety of cell functions, the researchers said. As such, it offers both a powerful new tool in **cancer and cardiovascular research**, as well as the potential to ultimately control complex processes such as nerve growth.
