The brain is forever chattering to itself, via electrical impulses sent along its hard-wired neuronal “Ethernet.” These e-messages are translated into chemical transmissions, allowing communication across the narrow cleft separating one neuron fr…
Princeton engineers have developed a sensor that may revolutionize how drugs and medical devices are tested for contamination, and in the process also help ensure the survival of two species of threatened animals.
To be fair, some of the credit …
Researchers have applied studies in how proteins bind with different molecules to create a molecular switch that enables them to turn an enzyme on and off. The innovation holds promise for a wide range of laboratory processes, including highly targeted drug therapies. The study, published this week in the Proceedings of the National Academy of Science, describes a reversible switch for the enzyme endoglucanase in which light is the trigger for turning the switch on and off.
