This Week in Science

In Science, a team from California reports on a class of genetic control systems called molecular network diverters that interface with a native signaling pathway to "route cells to divergent fates in response to environmental signals without modification of native genetic material." They also describe a method for identifying control points within natural networks that enables the construction of synthetic control systems for activating or attenuating native pathways to direct cel
