PITTSBURGH, July 9, 2015 - Starting anti-HIV treatment within two weeks of the diagnosis of tuberculosis, or TB, improved survival among patients with both infections who had very low immune-cell counts, according to an analysis by researchers at the University of Pittsburgh Graduate School of H...

For decades, researchers have worked to improve cacao fermentation by controlling the microbes involved. Now, to their surprise, a team of Belgian researchers has discovered that the same species of yeast used in production of beer, bread, and wine works particularly well in chocolate fermentati...

Tom talks with Vincent about viral central nervous system infections of global importance, Ebola virus, and running the fastest marathon dressed as a doctor.
Vincent, Dickson, and Daniel explain how trypanolytic factor forms membrane channels to lyse trypanosomes, and present a new case study.
Scientists behind the first global distribution maps of two species of dengue and chikungunya-carrying mosquitoes warn they are spreading to new areas where they could cause disease. Read More

Neutralizing antibodies (Nabs) are immune proteins that recognize, bind to, and trigger the elimination of virus before it can establish a chronic infection. How to elicit a potent Nab response capable of protecting against different HIV subtypes and against different modes of infection is criti... 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.
Vincent, Alan, and Kathy continue their coverage of the Ebola virus outbreak in West Africa, with a discussion of case fatality ratio, reproductive index, a conspiracy theory, and spread of the virus to the United States.

Dear Vincent, Dickson and Daniel,
Scientists have engineered yeast cells that can “talk” to one another using a versatile plant hormone called auxin.
Typically, these simple fungal cells (Saccharomyces cerevisiae) usually do their jobs—making bread rise or converting sugar into alcohol—without having to communicate or work to... Read More
