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

David Tuller, health journalist and Berkeley faculty member, has written a piece on the CDC's handling of CFS. His account draws from interviews, a close reading of a fraction of the 4608 epidemiologic studies that pop up on a PubMed search for “chronic fatigue syndrome,” and a review of many pa... Read More
Influenza A virus reservoirs in animals have provided novel genetic elements leading to the emergence of global pandemics in humans. Most influenza A viruses circulate in waterfowl, but those that infect mammalian hosts are thought to pose the greatest risk for zoonotic spread to humans and the ... Read More
This episode: Our archaeal ancestors may have been more important to us than bacterial!
In TWIV 173, you talked about a study on antibody levels to bird flu (H5N1) in various populations, and related this to infections that don't cause serious enough illness to send someone to the hospital, or perhaps to get them teste... Read More
The Judges' Choice for The Scientist magazine's 2011 Labby Multimedia Awards is this cute video on how microbes are essential for snow formation.
The findings by the NIH and FDA that XMRV is associated with chronic fatigue syndrome has been accepted for publication by the Proceedings of the National Academy of Sciences (PNAS). Release of the article has been blocked by PNAS due to work carried out by the US Centers for Disease Control and... Read More
A recent paper published on Biomedcenteral by Jonathan E Allen , Shea N Gardner , Elizabeth A Vitalis, and Tom R Slezak discovers that new genetic markers for human host-specificity and high lethality in influenza viruses were identified by considering combinations of amino acids conserved amon...

Some additional info that I gathered on viruses on the verge of elimination (may or may not be new to you):
It appears that the next virus on the list of FAO to eradicate is PPR virus ( Read More
Vincent, I am a huge fan of TWIV and thank you and the others for taking time out of your busy schedule to do the program. I have my B.S. in Biology and Chemistry and would love to go back to school. I read textbooks, listen to podcasts from itunesU and... Read More
This is a great online children's book about the role of bacteria in our lives by Dr. Mel Rosenberg for ages 3+. Read More
Aaron J. Shatkin was well known for his work on reoviruses beginning in the 1960s in his laboratory at the Roche Institute of Molecular Biology in Nutley, NJ and then at Rutgers University. He was among the first to appreciate that virus particles contained many different enzymes, such as RNA po... 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
A dairy cow in California is the fourth known American case of mad cow disease, which is caused by prions, infectious agents composed only of protein (the story hit the press the day after my lecture on this type of illness). Unlike viruses, prions have no nucleic acid and no protective coat. Bu... Read More
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...

I have heard recently that some types of herpes virus may protect us from bacterial infections. This made me remember of myxomavirus, viral oncotherapy and how tumor cells have a compromised immune response. Do you think it is possi... Read More
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
Merry Youle from the Small Things Considered blog ponders the potential size a virus can be:
"With such fascinating stories being told by Mimivirus and the other giants, people are now looking for them in more environments. Modified techniques are called for, as those used previously to spot ... Read More
