When cells experience enough chronic stress, they can stop dividing permanently. In this state of cellular limbo, known as replicative senescence, cells remain alive but no longer proliferate.

Edward Lyman, associate professor in the departments of physics and astronomy, as well as chemistry and biochemistry, was recently published in the journal Nature Chemical Biology. The article, “When ...

Membrane proteins and membrane lipids are essential partners in various biological processes, and elucidating their structures in a natural membrane environment is crucial for enhancing our ...

Researchers in Bochum have discovered a control mechanism that may also operate beyond plants. Proteins carrying a "tail anchor" must be inserted into the ER membrane before they can fulfill their ...

A new study shows that lipid droplets in the leaves contain plant proteins such as different myosin binding proteins involved in intracellular movement, and several enzymes responsible for ...

Scientists have identified a new type of protein in bacteria that could change our understanding of how these organisms interact with their environments. A new study, published in Nature ...

Why do cells age—and why do we lose our energy and vitality as we get older? This question is one of the central challenges ...
