On a recent episode of TWiV, we posed the question, 'Can computer viruses evolve'? and asked listeners to weigh in. The author of the blog nostacktrace spent some time thinking about this issue and concludes that the evolution of real computer programs doesn't really work. Software instructions ... Read More
The second RNA segment of some influenza virus strains encodes a protein called PB1-F2 that might contribute to virulence. Speaking about the 2009 pandemic H1N1 strain, Peter Palese noted that “If this virulence marker is necessary for an influenza virus to become highly pathogenic in humans or ... Read More
Now that we have experienced several months of the H1N1 pandemic, what have we learned about how it was handled? Watch Dr. Nicole Lurie (U.S. Department of Health and Human Services) and Dr. Kathryn Edwards (Vanderbilt University), discuss the public health responses to H1N1. Participants compar... Read More
Selective losses of human-associated microorganisms may be responsible for a wide range of modern ailments, including esophageal diseases, obesity, asthma, and the epidemic spread of high-grade pathogens, according to Martin Blaser from New York University Langone Medical Center in New York City...

The emerging field of synthetic biology will allow researchers to create biological systems that do not occur naturally as well as to re-engineer existing biological systems to perform novel and beneficial tasks. As the science and its applications develop, a com... Read More
The World Health Organization and the US Food & Drug Administration have decided on the composition of the influenza virus vaccine that will be used during the 2010-2011 season in the northern hemisphere. The trivalent preparation will contain the following influenza virus strains: A/California/... Read More
Few technical breakthroughs have changed the face of their field like the Polymerase Chain Reaction (PCR). Gene cloning, sequencing of complex genomes, DNA fingerprinting and DNA-based diagnostics are just some of the techniques that were either inefficient, crude or plain impossible before PCR....

We speak with many scientists each week who are working with filtered water for the isolation of microbial DNA and RNA. Because there are many choices for filter membranes, each with their own benefits, choosing the best one for your sample type and microbial load can be confusing. This article ... Read More
While almost every lab has a small toolbox with some screwdrivers, pliers, and such, here are some tools that may not have obvious utility at the bench, but could make your life easier. Jode Plank, a Postdoctoral Fellow studying DNA repair at the University of California at Davis shares some of ... Read More
In this monthly interview series, meet Erin Sanders-Lorenz, an Adjunct Assistant Professor in the Department of Microbiology, Immunology, & Molecular Genetics at UCLA , co-author of the new book, "I, Microbiologist: A Discovery-based Course in Microbial Ecology and Molecular Evolution" and a lea...

On episode #72 of the podcast This Week in Virology, Vincent, Dickson, Alan and Rich explain CRISPR/Cas, the immune system of bacteria and archaea, how novel viruses are discovered by deep sequencin... Read More
Presenting your work is a fantastic opportunity to get feedback on your project, demonstrate the significance of your results, and make the connections that will enhance your future career. And yet, how many incomprehensible lab meetings have we all sat through? How many seminars have you attend... Read More
No matter what advanced method is used to develop and produce vaccines, their efficacy is limited by old technology – the refrigerator. All viral vaccines must either be stored frozen, or kept at low temperatures. If they are not properly stored, they lose potency and do not confer protection ag... Read More
Moselio Schaechter at Small Things Considered highlights 4 student blogs that "gladden an old man's heart."
In Catalogue of Organisms, Christopher Taylor, a student of arachnids... Read More
The most comprehensive way to evaluate DNA concentration and purity is to use both UV spectrophotometeric measurements and agarose gel eletrophoresis. This quick reference guide gives an overview of the information that can be derived from both.
This article is a clear and concise guide to th... Read More
You are going to spend at least 4 years or more in graduate school, and around 3-5 years in a postdoc position. That’s a big chunk of your life, so apart from doing experiments, writing papers or your thesis and maybe doing some teaching, what else are you doing?
To paraphrase one of my favor... Read More
