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
The third annual installment of my virology course at Columbia University, Biology W3310, has begun, and all the lectures will be available online. Read More
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
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
El podcast del Microbio Nº194 is about the recent observation that the algae Closterium moniliferum could remove strontium... Read More
Re the letter you got about a Spanish version of TWIV: ASM already has a nice Spanish microbiology podcast, called Mundos de los Microbios. Your TWIM co-host Elio has been on that podcast at least once that I’ve heard. Perhaps you could p... Read More
This 2000 paper, published in Chest, shows that chicken soup is capable of inhibiting neutrophil chemotaxis in vitro, thus providing some evidence for the soup's traditional role as a home cure for respiratory infections.
Helpfully, the soup recipe used in the study is also included. And it ... Read More
A laboratory in the Netherlands has identified a lethal influenza H5N1 virus strain that is transmitted among ferrets. These findings are under review by the National Science Advisory Board for Biosecurity (NSABB) to ensure that they do not constitute a threat to human health. Meanwhile both the... Read More
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
Are you interested in proposing an interdisciplinary topic with maximum appeal? Do you have an idea for a core colloquium or symposium of scientific significance? ASM's General Meeting Program Committee is soliciting suggestions to help build the program for asm2012 in San Francisco, June 16-1... Read More
A listener pick - since I know you all really enjoy the visualization of science!
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...

The expression “Happy as a Clam” comes with new meaning as hepatitis A virus has been detected in clams, mussels, and oysters in markets for human consumption. As bivalve shellfish are excellent bio-accumulators of contaminants and chemicals, it is no surprise that they also harbor waterborne vi... 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
I love your show very much and this is not my first comment. I load firewood and paint as I listen to you guys, thanks so much for the inspiration over what is becoming years. I'm not an audio learner, though my mind is quite stimulated by what I hear. ... 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
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
The protein components of the plaques and tangles seen in the Alzheimer's disease brain offer a clue to the origins of the disease: It turns out that they are heavily enriched in human proteins used by herpes simplex during its life cycle: Many immune system related proteins are also found in th...

Jamie Henzy, a postdoctoral researcher at Boston College, has authored a post on Small Things Considered that explores the shady world of the deltaretrovirus genus.
"Among retroviruses, the deltaretrovirus genus is something of a shady bunch, its members lurking in the shadows, causing troubl... Read More
