A transporter which some bacteria use to recycle fragments of their cell wall has been discovered. Researchers found that the transporter controls resistance to certain kinds of cell-wall targeting ...

The bacterial cell wall must be constantly remodeled in order to grow and divide. This involves the close coordination of lytic enzymes and peptidoglycan synthesis. Researchers led by Martin ...

Endolysins are phage‐encoded enzymes that degrade the peptidoglycan layer of bacterial cell walls, a process essential for the release of progeny virions. Their ability to precisely cleave key bonds ...

Scientists have uncovered a direct molecular mechanism by which gut bacteria inject proteins into human cells, reshaping immune responses and potentially driving inflammatory disease. Scientists have ...

Why dead bacteria are the secret to a happier gut - Postbiotics are stealing the spotlight for their ability to support ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Quick, can you describe your grandparents?

Bacteria are experts at evolving resistance to antibiotics. One resistance strategy is to cover their cell walls in sticky and gooey biofilm that antibiotics cannot penetrate. A new discovery could ...

With just an incubator and some broth, researchers can grow reusable filters made of bacteria to clean up polluted water, detect chemicals in the environment and protect surfaces from rust and mold.

University of Otago scientists are harnessing the power of peptides – the body's own tiny protein molecules – for a spray to help the red meat industry solve headaches around bacterial contamination ...

Antibiotic resistant bacteria are experts in evolving new strategies to avoid being killed by antibiotics. Bacteria strains can evolve individually and mutate quickly and constantly when they are ...
