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
Listening to Life: New chemical imaging method probes the communications of live microbial colonies
Once impossible, scientists can now eavesdrop on microbes, thanks to a new technique from scientists at Pacific Northwest National Laboratory and three universities. Microbes converse by releas... Read More
Vincent, Alan, and Rich discuss how norovirus, an enteric virus, can replace the functions of the gut microbiome.
Humans and chimpanzees have much in common, biologically speaking, and that may now include certain communities -- or ecosystems -- of gut bacteria, a new study finds.
Gut bacteria play a crucial role in collecting nutrients from food, helping the immune system and protecting people against d... Read More
The agent of Lyme disease, Borrelia burgdorferi (Bb) has been shown to have the ability to hide and demonstrate resistance from harsh environmental conditions to antibiotics used to treat the infection, thanks to the formation of a biofilm, according to a University of New Haven news release Oct...

An outbreak of Ebola hemorrhagic fever that began in early July 2012 has involved at least 36 individuals and 16 deaths. So far the disease has been confined to a rural region west of Kampala, the capital of Uganda. The subject of Richard Preston’s scary The Hot Zone, Ebola virus is newsworthy b... 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
If you're a pet-owner who kisses your dog on the mouth, you might want to think twice.
A new study in the journal Archives of Oral Biology suggests that it's possible for disease-causing oral bacteria to be exchanged between dogs and their owners.
Japanese researchers examined dental plaqu... Read More
Welcome to the great state of Wisconsin! I hope you enjoy your stay. I suggest in your free time that you try some fresh cheese curds from a local creamer and maybe some fried ones too. I'm sure that those from the area can let you k... Read More
Carl Woese, a biophysicist and evolutionary microbiologist whose discovery 35 years ago of a “third domain” of life in the vast realm of micro-organisms altered scientific understanding of evolution, died on Sunday at his home in Urbana, Ill. He was 84.
His death was announced by the Universi... Read More
A bacterial protein in common house dust may worsen allergic responses to indoor allergens, according to research conducted by the National Institutes of Health and Duke University. The finding is the first to document the presence of the protein flagellin in house dust, bolstering the link betw... Read More
A fun little read about lichens and their impressive attributes, accompanied by some beautiful photographs. (If the use of the term "kingdom Monera" gives you cause to smirk, just ignore it and keep reading.) Read More
Boy, it's a good time to be a dark chocolate lover.
We've noted before the growing evidence that a daily dose of the bitter bean may help reduce blood pressure. There also seems to be a link between a regular chocolate habit and lower body weight.
Now scientists are offering an explanation... Read More

Bacteria talk to each other using N-acylhomoserine lactones (AHLs) as quorum sensing (QS) signals. This signaling allows the bacteria to control gene expression of virulence factors and biofilms once a critical density has been achieved. This phenomenon, quorum sensing, is important when an infe... Read More
Tomorrow starts the XVIII International Congress for Tropical Medicine and Malaria Conference here in Rio de Janeiro. I read Peter Hotez will be participating in a round-table session on “What is the future role of academic journals in the research, c... Read More
