Just like those of humans, insect guts are full of microbes, and the microbiota can influence the insect's ability to transmit diseases. A new study reports that a bacterium isolated from the gut of an Aedes mosquito can reduce infection of mosquitoes by malaria parasites and dengue virus. The b... Read More
Later this month (May 2014) the World Health Assembly will decide whether to destroy the remaining stocks of variola virus – the agent of smallpox – or to allow continued research on the virus at WHO-approved laboratories. We are interested in your opinion on this issue. Please follow the link t... Read More

A good immune system relies on a key ‘energy producing’ protein in immune cells to develop immunity to vaccines and disease, an international team of scientists has found.
The protein, called HuR (human antigen R) is critical for controlling metabolism in B cells, which make antibodies that a... Read More
Vincent, Dickson, and Daniel consider the delivery of anti-trypanosome nanobodies to the tsetse fly via a bacterial symbiont, and present a new case study.
Bioengineer Ingmar Riedel-Kruse of Stanford University has created a series of games where players control organic microbes.
The games, which you can see showcased in the video below, places a collection of single-celled protozoans called paramecia in a thumbnail-sized chamber with electrode-... Read More
When it comes to infecting humans and animals, bacteria need a helping hand.
Kansas State University biochemists have found the helping hand: groups of tiny protein loops on the surface of cells. These loops are similar to the fingers of a hand, and by observing seven individual loops on the ... Read More
The placenta is full of microbes, a new study finds, raising questions about how that ecosystem and mothers' oral health influence the risk of pre-term birth.
Even before a baby is born a microbial ecosystem takes up residence in the placenta, creating a microbiome that may help shape the new... Read More
