Stem cells in the gut sacrifice themselves to stop bacterial infection

A study by the Weizmann Institute and the Hebrew University reveals a new immune defense mechanism: stem cells infected with Salmonella accelerate their maturation, stop reproducing, and help save intestinal tissue.

Light-driven nanorobots successfully detect and collect bacteria

Researchers from the University of Würzburg have developed tiny robots, smaller than one micrometer, that are propelled by photon repulsion and capable of manipulating bacteria in a liquid environment.

The secret 'sex life' of bacteria: Study challenges old ideas about how species are formed

Researchers at the Georgia Institute of Technology have found that bacteria not only create species, but also maintain them in a unique process reminiscent of sexual reproduction.

Identifying new toxins using machine learning

New research at the Hebrew University reveals how bacteria use a special mechanism, like a tiny syringe, to inject toxins into other organisms. Using artificial intelligence, the researchers identified over 2,000 possible toxins that may be injected through
