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 b... Read More
To our TWIV leaders!

Glenn Rall, a virologist at Fox Chase Cancer Center, sent me the following note:
Baruch S. Blumberg, Nobel Laureate in 1976 for discovery of Hepatitis B (and the eventual development of the vaccine, which probably has saved hundreds of thousands of lives since its introduction), died this pas... Read More
The novel human retrovirus XMRV has been associated with prostate cancer and chronic fatigue syndrome. The nucleotide sequence of XMRV isolated from humans indicates that the virus is nearly identical with XMRV produced from a human prostate tumor cell line called 22Rv1. This cell line was deriv...

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 ... Read More
This episode: Viruses take over caterpillars' behavior!

As a microbiologist I enjoy listening to your broadcasts. However, I was very disappointed on the one about Salomonella in cantaloupe and E. coli O157:H7 in Lebanon bologna. Many incorrect statements were made, such as "Salmonella enteritidis is th... Read More
If you know anything about snakes you might be familiar with snake inclusion body disease, or IBD. This transmissible and fatal disease affects snakes of a variety of species but has been best studied in boas. The name comes from the presence of large masses (inclusions) in the cytoplasm of cell... Read More
The CDC has just published "Preparing for the Flu: A Communication Toolkit for Child Care and Early Childhood Programs." A .pdf document that provides information and communication resources to help center-based and home-based child care programs, Head Start programs, and other early childhood p... Read More
Science writer Carl Zimmer writes a masterful blog piece tracing the history of the study of ecosystems, from lakes to the human microbiome. Just one interesting fact: In their lifetimes, individual humans will produce about five elephants worth of microbes. Read More
I've been having an enjoyable time on my commute lately catching up with TWiV. Today I listened to #26 (Poxviruses), which included a discussion of Tysabri and PML. I work at Millipore which sells many products that go into a MAb production train, includ... Read More
