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...

Yesterday I sent my Skype audio question again, and I think it worked this time. In my question I mentioned a particular youtube video. Here's the link if you want to see what I was referring to. It's only 5 minute... Read More
This teleconference is sponsored by the American Society for Microbiology and will review the history and importance of methicillin-resistant Staphylococcus aureus (MRSA) with a primary focus on the emergence of community-associated MRSA (CA-MRSA). The phenotypic and molecular identification of ... Read More
Dear Twiv Folks
I teach an intro biology course on viruses at Vassar College. We do our introductory biology a little bit differently; each class has a theme through which we explore the fundamental principles of biology. Mine is on viruses and t... Read More
How about using compost that includes road kill? I heard a billion pounds of animal byproducts go to landfills rather than into animal feed to prevent spread of mad cow disease. Compost that, too?
Jeff Fox of Microbe magazine interviews Kim Lewis of Northeastern University--
Missing siderophores may account for why microbiologists can culture only about 1% of the microorganisms that they collect from diverse environments, according to Kim Lewis of Northeastern University and his collabor... Read More
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
Dear TWiV Captain and Officers,
I am a Swedish listener in my fifties, with a neolithic MSc in computer science and nowadays active within software quality (and yes, that's an oxymoron...). I found TWiV in September 2010 and I hav... Read More
A second virophage has been identified. The name does not signify a virus that infects another virus – it means virus eater.
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
When my laboratory discovered the cell receptor for poliovirus in 1989, many new research directions were suddenly revealed – such as creating a mouse model for poliomyelitis. One application we did not think of was to use the receptor to screen samples of drinking water for the presence of viru... Read More
I saw this video during the course of listening to TWiP. Is there any parasitic truth behind this phenomenon?

I did the homework Professor Vince assigned and went to see the movie Contagion. I really liked the movie and was very pleased with the way the science was portrayed.
I am an Environmental Health and Safety Manager ... Read More
At first glance, the inaugural 1812 issue of the New England Journal of Medicine and Surgery, and the Collateral Branches of Science seems reassuringly familiar: a review of angina pectoris, articles on infant diarrhea and burns. The apparent similarity to today's Journal, however, obscures a fu... Read More
An article by Alan Derman, Project Scientist in Joe Pogliano’s lab at the University of California at San Diego, published on the Small Things Considered blog presents a point-by-point analysis of a paper "Quantitative genome-scale analysis of protein localization in an asymmetric bacterium" pub...

Rich Condit found an article highly critical of the original Wakefield study (claiming a link between MMR vaccine and autism) which was published in the same issue of Lancet. He asked the publisher, Elsevier, to open up the article to non-subscribers so he could recommend it as a pick of the wee... Read More
Yesterday the Chicago Tribune published my reaction to the four papers on the retrovirus XMRV published this week in the journal Retrovirology. I was quoted as saying ”These four papers are probably the beginning of the end of XMRV and CFS”. I wish to retract this statement and explain my reason... Read More
