Despite surgeons’ best efforts, bacteria often manage to sneak onto medical implants such as bone screws, where they can cause severe infections. Research published today in Nature Communications suggests that using fluorescent antibiotics could reveal such infections before they become too seve... Read More
The NDSU Department of Veterinary and Microbiological Sciences researchers discovered that B-phenylethylamine, or PEA, reduced the number of cells of Escherichia coli in a beef broth. PEA is a substance found in chocolate in trace amounts. Health food stores sell it in pill form to improve peopl... Read More
In a hot, steamy lava cave on the Kilauea Caldera in Hawai’i, microbiologists collecting samples from a dripping purple mat on the cave floor have found a new species that could reveal how bacteria that spit oxygen into the atmosphere millions of years ago evolved.

It's a mould breaker. Researchers have discovered the first fungus that behaves like a farmer.
We already know that soil fungi can help bacteria travel quickly from A to B. The fungal filaments provide favourable conditions for the bacteria, and so act as "highways" through the soil. But thes... Read More
