Microbes collected from Northern California and throughout the nation will soon blast into orbit for research and a microgravity growth competition on the International Space Station (ISS). This citizen science project, known as Project MERCCURI, is led by UC Davis microbiologists, who are inves... Read More
An antimicrobial agent found in common household soaps, shampoos and toothpastes may be finding its way inside human noses where it promotes the colonization of Staphylococcus aureus bacteria and could predispose some people to infection. Researchers at the University of Michigan report their fi... Read More
ANYONE who walks in the woods will be familiar with witches’ brooms (pictured). Many trees sport these bushy tumours, which have a variety of causes. An important one is a group of bacteria called phytoplasma that are, in turn, carried from plant to plant by sap-sucking insects such as leafhoppe... Read More
