Blow up a long balloon and two things happen: it gets longer and it gets wider. Now imagine a living cell that inflates itself under enormous pressure and yet only grows longer, never adding width.

Researchers have identified two gut bacteria that can produce serotonin, a key chemical that regulates bowel movements. In experiments with mice lacking serotonin, the microbes boosted serotonin ...

Researchers simulated nearly every molecule in a bacterial cell — and then watched the cell grow and reproduce.

Researchers have revealed how a common bacterium, Enterococcus faecalis (E. faecalis), releases lactic acid to acidify its surroundings and suppress the immune-cell signal needed to start a proper ...

Drug-resistant bacteria are becoming harder to treat, pushing scientists to look for new antibiotic targets. Researchers have now discovered that several unrelated viruses disable a key bacterial ...

Restoring the gut microbiota through fecal microbiota transplantation reversed these effects. The treatment replenished CX3CR1-positive NK cells, reduced lung damage, and improved survival. Targeted ...

Researchers from Umeå University, Sweden, and Cornell University, U.S., have discovered a widespread mechanism in bacteria that enhances the bacteria's defense against environmental threats. The ...

By simulating the life cycle of a minimal bacterial cell—from DNA replication to protein translation to metabolism and cell ...

Bacteria are a cornerstone of the pharmaceutical and chemical industries, helping produce everything from drugs and beer to biodiesel and fertilizer. The pharmaceutical industry, in particular, relies ...

The core of a solid, cancerous tumor is comprised of dead cells and is oxygen-free, making it an ideal breeding ground for ...

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