How the cell protects itself

The cell contains transcripts of genetic material, which migrate from the cell nucleus to another part of the cell. This movement protects the genetic transcripts from the recruitment of "spliceosomes." If this protection ...

Bactericidal action of violacein revealed

In an article published in the journal ACS Infectious Diseases, Brazilian researchers describe the bactericidal action mechanism of violacein, a violet pigment produced by environmental bacteria, especially Chromobacterium ...

How cytoplasm 'feels' to a cell's components

Under a microscope, a cell's cytoplasm can resemble a tiny underwater version of New York's Times Square: Thousands of proteins swarm through a cytoplasm's watery environment, coming together and breaking apart like a cytoskeletal ...

Collaborative research reveals a new view of cell division

Basic research into the mechanisms of cell division, using eggs and embryos from frogs and starfish, has led researchers to an unexpected discovery about how animal cells control the forces that shape themselves.

New light on bacterial microcompartments

Bacteria contain "microcompartments," which are poorly understood organelles that play critical roles in metabolism. Understanding how they work may ultimately enable engineering them for useful applications. In salmonella, ...
