On episode #91 of the podcast This Week in Virology, Vincent, Dickson, Alan, Rich and Welkin discuss the nature, origin, and evolution of endogenous retroviruses (ERVs), and the recent finding of en... Read More
Dear TWiM Team
A fascinating article from New Scientist this week.
Standard medical teaching is that the foetus is sterile and that the microbiome only begins to develop post natal.
New research from Spain indicates that the microbiome s... Read More
Dear Mr. Racaniello and Dick,
Thanks for TWIV and TWIP as both are great shows. Such a give and take of history, information and humor. Stumbled across TWIP several weeks ago and gave it a try. My only disappointment was there were not many podc... Read More
The NIH Human Microbiome Project, initiated in 2008, is a five-year endeavor at capacity building and creating a community resource to support this emerging field. As a part of developing community resources, the HMP is announcing: 1) key findings on a very large study of the microbiomes of heal... Read More
Contemporary human viruses most likely originated by cross-species transmission from non-human animals. Examples include HIV-1, which crossed from chimpanzees to humans, and SARS coronavirus, which originated in bats. Since the 1989 discovery of hepatitis C virus (classified as a hepacivirus in ...

A salt-loving (halophilic) bacterium which can grow in medium containing arsenic instead of phosphorus has been selected from the microbial community of Mono Lake in California. Arsenic (As) is a chemical analog of phosphorus and is usually toxic because it can enter metabolic pathways in the pl... 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

Hello TWiV hosts,
I'm currently working as a technician in the biochemistry and molecular biophysics department at Columbia, having just received my BA from here in the Spring. First of all, I'd like to join the chorus of praises ... Read More
Norton Zinder made two important discoveries in the field of virology. While a Ph.D. student with Joshua Lederberg at the University of Wisconsin-Madison he found that viruses of bacteria (bacteriophages) could move genes from one host to another, a process called transduction. Later in his own ... Read More
Elio Schaechter of Small Things Considered has authored an interesting post today about the motility of bacteria, specifically Paenibacillus, although he does highlight several other strains that swarm, glide or twitch.
"Microbes get around. They can be carried by the wind, by insects, or by ... Read More

I'm just writing to clarify my question about the production of the flu vaccine if one of the other seasonal strains was removed as there seemed to be a bit of confusion about the point of it.
As I understand it one of the biggest holdups in seas... Read More
