I just returned from Dublin where I was honored to receive the Peter Wildy Prize for Microbiology Education from the Society for General Microbiology. This prize is awarded annually for an outstanding contribution to microbiology education, including university teaching, education of the general public, school pupils or professional groups. Below is a video of my acceptance …
Some viruses that infect bacteria (bacteriophages) deliver their DNA into the host cell with an amazing injection machine. The tailed bacteriophages (such as T4, illustrated) store their DNA in a capsid attached to a long tail tube that is surrounded by a sheath. At the bottom of the tube is a baseplate with a spike …
A consequence of the recent warm weather in the northeastern United States is the emergence of crocuses, an event that I documented at the TWiV Facebook page. A reader replied that it reminded her of the highly valued tulips with beautiful variegations produced by viruses. In 17th-century Holland patterned tulips such as the Semper Augustus (image) …
It is spring break for students at Columbia University, which means that my annual virology course is one lecture past the halfway point. The first eleven lectures addressed basic aspects of viral replication in cell culture, including virus entry into cells, genome replication, and assembly. From this point onwards we will be discussing viral infection of …
The fatality rate for human infections with avian influenza H5N1 is widely quoted at >50%, based on the number of deaths among the fewer than 600 cases confirmed by the World Health Organization. Wang, Parides, and Palese suggest that this number is an overestimate: …the stringent criteria for confirmation of a human case of H5N1 …

For the second time in a week I note the passing of an important virologist. Renato Dulbecco, together with David Baltimore and Howard Temin, received the 1975 Nobel Prize in Physiology or Medicine for discoveries about how tumor viruses interact with the genetic material of the cell. Dulbecco also devised my favorite virological method, the plaque …
