Baylor University researchers have developed a novel approach to fight colorectal cancer, using modified bacteria as a courier to deliver potent cancer-killing proteins into tumor cells. Michael S.

Endosymbiotic organisms have to live inside of another to survive, and this relationship often provides benefits for both the host and its resident. It may seem unusual, but complex cells are thought ...

Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and ...

The microbes in the human gastrointestinal tract can have a significant influence on human health and disease, and this gut microbiome has been associated with a wide array of characteristics and ...

Viruses attack nearly every living organism on Earth. To do so, they rely on highly specialized proteins that recognize and bind to receptors on the surface of target cells, a molecular arms race that ...

Researchers describe the full molecular structure of the phage DEV. DEV infects and lyses Pseudomonas aeruginosa bacteria, an opportunistic pathogen in cystic fibrosis and other diseases. DEV is part ...

Darwin's theory of natural selection provides an explanation for why organisms develop traits that help them survive and reproduce. Because of this, death is often seen as a failure rather than a ...
