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.

Solving the mystery behind how nutrients enter cells

For the nutrients that feed our cells to reach their destination, proteins embedded in the cell membrane often must shuttle what's needed across the threshold. When this system breaks down and metabolites fail to reach their ...

Worms in space—the molecular muscle experiment

Thousands of worms are being flown to the International Space Station later this year for scientists to understand more about spaceflight-induced muscle loss—the first UK experiment to take place on the International Space ...
