Dr, Francis Su is a mathematician at Harvey Mudd College in Southern California. Last week, he was honored with the prestigious Haimo Teaching Award of the Mathematics Association of America at the Join Math Meetings in San Diego. His acceptance speech is inspiring to any educator and any stud... Read More
Microbes can tailor transcriptional responses to diverse environmental challenges despite having streamlined genomes and a limited number of regulators. We present data‐driven models that capture the dynamic interplay of the environment and genome‐encoded regulatory programs of two types of prok... Read More
Morehouse College Biology students Rob Williams and Tony Gibson present on the process of Taq production and the polymerase chain reaction. Read More
Here is a transcript of TWiM episode #49, "Grape-like clusters". Thanks to Frank Shinneman for transcription.
A new post on the Bulletin for Atomic Scientists website reviews the U.S. Army's revised regulations for its biomedical labs. The updated requirements intends to clarify vague language in civilian biological agents guidelines. In addition, "the new regulations establish stricter controls on t... Read More
The TWiVome discusses an miRNA based strategy to mitigate risk of gain of function studies, and identification of a second receptor required for Lassa virus entry.
Two back-to-back papers were published last week that provide a detailed analysis of what it would take for avian influenza H5N1 and H7N9 viruses to switch to human receptors. A single amino acid change in the viral hemagglutinin protein is sufficient to quantitatively change binding of the viru... Read More

A post by Manuel Sánchez, host of the Spanish blog, Curiosidades de al Microbiologia, on an article entitled "Physical Virology " that appeared in Nature Phyisics, discuses the ideas and potential of a new discipline that studies viruses from a physical perspective.
"Viruses are able to spont... Read More
Elio Schaechter of Small Things Considered describes the work by members of Jill Banfield’s lab at Berkeley on a unique set of mine-dwelling microorganisms dubbed ARMAN (for Archaeal Richmond Mine Acidophilic Nanoorganisms). These microbes illustrate many surprising characteristics such as "thei... Read More

Greetings Vincent and Dick,
Hooray for finally mentioning G. pulchrum in episode 62, my most favorite parasite and one worthy of further discussion. As a diagnostic veterinary pathologist, I encounter this spirurid in approximately... Read More
Here's a nice edu resource-related video about the biology of bacteria that the team over at SciVee.tv posted. It looks like it originally came from Maryland Public Television. This is probably good for many intro to microbiology type courses and high school level life science classes. Read More
Here is a transcript of TWiM episode #6, "Antibacterial therapy with bacteriophage: Fact or fiction?". Thanks to Steve Stokowski for transcription.

Dr. Tony Fiore discusses who should be vaccinated against 2009 H1N1 flu during the 2009-2010 season. He explains the target groups for vaccination, and how these groups differ from those recommended for seasonal flu vaccination. Read More
Bacteria have been sexually promiscuous, swapping genes with gusto, for a very long time. More than 15% of E. coli's genome has arrived via horizontal gene transfer (HGT), with some 200 installments having turned up since it diverged from Salmonella 100 million years ago. And, as you are probabl... Read More
