Hello Professor Vincent,
First of all, thank you for your wonderful podcasts! I'm a CFS sufferer and also a student Applied Science so I'm interested in many of the topics discussed for those two reasons and always learning new things.

A team of researchers from The Wistar Institute has identified a protein that could serve as a target for reprogramming immune system cells exhausted by exposure to chronic viral infection into more effective "soldiers" against certain viruses like HIV, hepatitis C, and hepatitis B, as well as s...

A type of human encephalitis – an infection of the brain – has been known to affect the indigenous people living in the Sakha Republic of Russia since the mid-1800s. The available clinical and epidemiological evidence suggests that the disease is caused by a pathogen, but proving this has been d... Read More
Hello to the TWiV crew,
Here are a couple of picks I thought would be good for provoking thought and generating discussion...
While working on a project, I came across some papers attempting to define what "critical thinking" means. I app... Read More
There is an excellent question in the comments to “Are all virus particles infectious?“: if the particle-to-PFU ratio for a virus stock is 10,000:1, and I infect 1,000,000 cells with 10,000 particles, how many plaques would I expect to observe? Answering this question provides insight into the p... Read More
When infection with hepatitis C virus goes from acute to chronic, severe liver disease may occur which requires organ transplantation. Nearly 200 million people are chronically infected with HCV, necessitating approaches to preventing and treating infections. No HCV vaccine is available, and cur... Read More
A second virophage has been identified. The name does not signify a virus that infects another virus – it means virus eater.
The virologists who carried out the contentious experiments on influenza H5N1 transmission in ferrets have agreed to remove certain details from their manuscript, according to ScienceInsider. This is a bad day for virology, and for science in general. The decision by the NSABB sets a precedent f... Read More
Australian virologist Frank Fenner, MD was born in Ballarat, Victoria in 1914. He earned a Doctor of Medicine in 1942 at the University of Adelaide, and from 1940 – 1946 he worked on the malaria parasite in Egypt and Papua New Guinea as an officer in the Australian Army Medical Corps. He subsequ... 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
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
On the Small Things Considered blog, Michael Schmidt, Professor and Vice Chairman of Microbiology and Immunology at the Medical University of South Carolina, reviews a recent paper entitled "Precise Manipulation of Chromosomes in Vivo Enables Genome-Wide Codon Replacement" by Church and colleagu...

This is a great article by Carl Zimmer in the NY Times (@carlzimmer on Twitter) about the evolution process of viruses.
"Some viruses use DNA, like we do, to encode their genes. Others, like the influenza virus, use single-strand RNA. But viruses all have one thing in common, said Roland Wolk... 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
This past February I was interviewed by the Australian Broadcasting Company on the topic of the Fouchier and Kawaoka experiments on avian influenza virus H5N1. The video, Building the Perfect Bug, has been released by Journeyman Pictures and includes interviews with S.T. Lai, Laurie Garrett, Mic... Read More
The finding of viral nucleic acid sequences in illegally imported wildlife products has attracted the attention of the New York Times, which published an article entitled From the jungle to J.F.K., viruses cross borders in monkey meat. Read More
One hundred million years ago the earth’s climate was much warmer than today and vast inland seas stretched across entire continents. The land was dominated by charismatic megafauna that would one day serve as inspiration for Sir Arthur Conan Doyle’s novel The Lost World. This period is commonly... Read More
According to the New York Times (Why Science Majors Change Their Minds), the decline in the number of science majors in the United States has come about in part because the subject matter is too difficult. If this explanation is true, then we have not properly prepared these students in grades K... Read More
Some time ago I emailed you about transcribing an episode of TWiV and have finally finished episode 60. Let me join the chorus of appreciative listeners in praise for your podcast! I've learned a lot from it I was inspired by your generosity... Read More
This is a really cool Google Maps mash up that geo-locates breaking health news on a map. You can sort by official government announcements, news wires, infectious disease types, zoom to countries, local areas and more. Great for looking at Swine Flu reporting as it happens. Read More
