Light-activated molecular machines get cells 'talking'

One of the main ways cells "talk" to each other to coordinate essential biological activities such as muscle contraction, hormone release, neuronal firing, digestion and immune activation is through calcium signaling.

Scientists map the distribution of carnitine in muscle cells

Researchers from Tokyo Metropolitan University have developed a way of mapping the distribution of carnitine in skeletal muscle cells. Carnitine is a compound that helps transport fatty acids and reduce metabolic byproducts. ...
