Robert H. Silverman, one of the authors on the study implicating the new human retrovirus XMRV as an etiologic agent of chronic fatigue syndrome, has written an excellent review article on the current status of research on the virus. The article is behind a paywall at Nature Reviews Urology, so I’ll provide a summary of …

One property of viruses that is difficult to conceptualize is their small size. I can tell you that viruses can be anywhere from 20 to 750 nanometers in diameter, but that’s not easy to visualize, even for those of us who routinely work with small measurements. One way to demonstrate how small viruses are is …
A serious shortcoming of current influenza virus vaccines is the need to reformulate them every year or two as the virus undergoes antigenic drift. Many virologists have been captivated by the idea of a more universal vaccine that would endure longer, perhaps a decade or more. The identification of a conserved domain in the stalk …
In the final lecture of my virology course, Professor Dickson Despommier weaves a story about the arrival of West Nile virus to the United States in the summer of 1999. This is a special treat that you won’t want to miss, as Prof. Despommier is a wonderful storyteller. Download: .wmv (422 MB) | .mp4 (108 …
An important question about the retrovirus XMRV, which has been implicated in prostate cancer and chronic fatigue syndrome, is where the virus replicates in humans. Such information would provide clues about how infection might be transmitted. To date the virus has been detected in malignant prostate cells and in the peripheral blood mononuclear cells and …
Google Flu Trends uses analysis of large numbers of search queries to track influenza-like illness in a population. The idea is that the frequency of certain queries correlates with the percentage of physician visits in which a patient presents with influenza-like symptoms. Google claims that it can accurately estimate the level of weekly influenza activity …
