For the first time, researchers have demonstrated a means of controlling cell functions with a physical, rather than chemical, signal. Using a magnetic field to pull together tiny beads targeted to particular cell receptors, Harvard researchers made cells take up calcium, and then stop, then take it up again. Their work is the first to prove that such a level of control over cells is possible. If the approach can be used with many cell types and cell functions, it could lead to a totally new class of therapies that rely on cells themselves to make and release drugs.
