The anti-bacterial gel, which can be

A Band-Aid is placed on a skinned knee. Drops go into itchy eyes. A broken arm goes into a cast. But often what ails us is inside

Scientists have created the first completely artificial protein switch that can work inside living cells to modify–or even commandeer–the cell’s complex internal circuitry. The switch is dubbed LOCKR, short for Latching, Orthogonal Cage/Key pRotein. Companion papers published July 24 in the journal Nature describe LOCKR’s design and demonstrate several practical applications of the technology. The

The future of faster, more efficient information processing may come down to light rather than electricity. Mark Lawrence, a postdoctoral scholar in materials science and engineering at Stanford, has moved a step closer to this future with a scheme to make a photon diode – a device that allows light to only flow in one

Nature follows a different strategy in biochemical synthesis. The majority of biochemical reactions are driven by machine-type protein complexes that bind
