Bitter tasting yogurt or cheese may not make it to your refrigerator, but it is produced and the result of pesky bacteria. The microbial composition of raw milk impacts the quality, shelf life, and safety of processed milk and other dairy products. Controlling the quality of these products is tr... Read More
Biofilms, surface-attached microbial communities encased in an extracellular matrix, are one of the most common macroscopic microbial structures we can see in nature. Biofilms like those seen in pond scum, in dental plaque, or in hot springs, are mixed communities with the members forming both a... Read More
A new blog written by undergraduate students from the School of Genetics and Microbiology, Trinity College Dublin features Vincent Racaniello, PhD, host of This Week in Virology.
"Most students studying science at university will inevitably become familiar with the names and works of a wide r... Read More
For the article letter about microbial batteries, I think CV refers to Capacitance times Voltage, which is stored charge. In electronics, current is abbreviated I not C.
The claim in the letter got me thinking about microbial batteries and I wrote ... Read More
Polio returns to Nigeria after two years - but it turns out it had never gone away.

The TWiVome reveal the first eukaryotic genes found in a bacteriophage of Wolbachia, and how DNA tumor virus oncogenes antagonize sensing of cytoplasmic DNA by the cell.
The TWiVnauts present another example of an infectious but replication incompetent vaccine, an insect specific arborvirus bearing chikungunya virus structural proteins.
At the Hamilton, Montana Performing Arts Center, Vincent speaks with three local high school graduates and two high school teachers about how Rocky Mountain Laboratories influenced school science programs and opened up career opportunities.

It has been speculated that the development of neurological disease and fetal abnormalities after Zika virus infection may be due to the presence of antibodies against other flaviruses that enhance disease. In support of this hypothesis, it has been shown that antibodies to dengue virus enhance... Read More
The TWiVestigators wrap up 2016 with a discussion of the year's ten compelling virology stories.
In this new video episode of Virus Watch, you'll see how the Zika virus particle is built, and how it binds to an antibody that blocks infection. All in gorgeous three dimensional views provided by recent structure studies. Read More
The TWiVaniellos discuss a thermostable poliovirus empty capsid vaccine, and two cell genes that act as a switch between entry and clearance of picornavirus infection.
"Hivi and his team of viruses (Ebola, Pox,..etc) believe they can win the battle, but the Virologists (who are real famous professors) beat them. However, new viruses pop-up, it will be a long battle. This makes the story very interesting and ever so engaging."

Mapping and identifying all the microbes across New York City is no small feat. Just ask Jane Carlton. About three years ago, Carlton, director of the Center for Genomics and Systems Biology, and professor of biology, at New York University and colleagues won an NYU grand challenge grant for the...

One of the most dangerous places for an infection to occur is in the bloodstream. Septicemia, when microbes are present in the blood, not only allows bacteria access to other internal organs through the highway of our circulatory system, but also can cause a massive inflammatory response, leadin...
