Sugars, or glycans, play a crucial role in biology—from cell signaling and recognition to interactions with pathogens.

Gliomas are malignant brain tumors that originate from glial cells, which do not produce electrical impulses like neurons but ...

Signaling is fundamental to how cells sense and respond to their environment—but in immune cells, those signals must be precisely amplified to mount an effective defense against invasive threats. New ...

The design of new calcium channels, built bottom-up from scratch, was reported last week in Nature. "Biochemists have been studying ion channels for decades and debating about how they work for almost ...

The enzyme RNA polymerase II transcribes genes into messenger RNA. This process is guided by modifications to the enzyme's "tail" called phosphorylation patterns. Scientists at St. Jude Children's ...

The cells lining skin capillaries are constantly sending each other messages—tiny pulses of calcium that help regulate blood flow, sense physical forces and keep vessel walls intact. Scientists have ...

“These proteins act as molecular instructions that tell stem cells when and how to develop into heart muscle cells. However, ...

A growing body of evidence suggests that a rare epithelial cell type known as the tuft cell may play a far more significant role in cancer than previously recognized.
