Cell walls are a crucial structure of plant life, protecting cells from damage, giving plants shape, and containing ...

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 ...

Cell division is an essential process for all life on Earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive—particularly for egg-laying species ...

Cells constantly probe their environments, searching for physical cues that guide their behavior. And yet a cell's response to its environment is always biochemical, mediated by the chemistry of its ...

In a groundbreaking study on the synthesis of cellulose -- a major constituent of all plant cell walls -- a team has captured images of the microscopic process of cell-wall building continuously over ...

(MEMPHIS, Tenn. – November 6, 2025) The enzyme RNA polymerase II transcribes genes into messenger RNA. This process is guided by modifications to the enzyme’s “tail” called phosphorylation patterns.

Microtubules perform an active role in communication within the cell by transmitting received signals to the cell's functional units. Researchers at the Paul Scherrer Institute PSI and the Department ...

When injured, cells have well-regulated responses to promote healing. These include a long-studied self-destruction process that cleans up dead and damaged cells as well as a more recently identified ...

After cells die, they leave a residue that sends messages to other cells in ways that are valuable to the immune system. But this process can also be hijacked by viruses such as influenza, according ...
