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 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 ...

Matthew Holland receives funding from the Engineering and Physical Sciences Research Council (EPSRC) and the Ineos Oxford Institute. A team of Romanian scientists drilled a 25-metre ice core from the ...

A strain of bacteria found in a Romanian ice cave is resistant to ten modern antibiotics, according to a new study. Frozen bacteria kept for 5,000 years in an underground cave have been found to be ...

A mysterious group of bacteria seems to thrive in the gut microbiomes of people without illness, hinting that they may be crucial to good health. Yet about two-thirds of these species are part of the ...

Researchers at Goethe University Frankfurt have discovered a surprising role for formic acid in the human gut: The small molecule acts as a kind of “taxi” for electrons – both within bacteria and, ...

Bacteria in the human gut can directly deliver proteins into human cells, actively shaping immune responses. A consortium led by researchers at Helmholtz Munich, with participation from Ludwig ...

A new report from the Centers for Disease Control and Prevention on the deadly drug-resistant bacteria NDM-CRE found a 70% rise in infections in the U.S. between 2019 and 2023. Also known as ...

The idea that a single-celled bacterium can defend itself against viruses in a similar way as the 1.8-trillion-cell human immune system is still “mind-blowing” for molecular biologist Joshua W. Modell ...

A new study from the CDC found that infection rates for a drug-resistant “nightmare bacteria” are on the rise, increasing nearly 70% between 2019 and 2023. The increase was primarily driven by the NDM ...
