Aged bacteria can still drive strong carbonate formation in microbial-induced carbonate precipitation systems when their apparent viability is measured properly and built into the treatment design, ...

Scientists at MIT have discovered that a little-known protein called intelectin-2 plays a powerful double role in defending the gut. The protein strengthens the mucus layer that lines the ...

Bacteria and the viruses that infect them are perpetually at war. Their deadly clashes push both kinds of microbes to evolve new traits that meet the challenges of every environment they inhabit, from ...

Microbial bioelectronic sensors use living bacteria that can create an electrical signal in response to the presence of a target substance, or analyte. These types of sensors offer many advantages ...

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 ...

The gut bacterium Bacteroides fragilis has long presented researchers with a paradox. It has been associated with colorectal cancer, yet it also lives quite happily in most healthy people. A study by ...

Viruses that infect bacteria can still do their job in near-weightlessness on the International Space Station (ISS). However, the pace of infection shifts, and both the virus and the bacterium start ...
