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.

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
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
This episode: Probiotic DNA can be good for our health!
The mantle of world’s biggest virus has passed from Mimivirus to Megavirus. But in this case, size doesn’t matter. It’s the genes that these viruses share and do not share that make this story important. Read More
I'm greatly concerned about the harmful effects of nanotechnology. I'm old, but have grand kids, who already have to live with all kinds of junk in the environment. I guess it's a topic that fits in the virology category, too, since are not nanotech-sized parti... Read More
Hello Professors Racaniello and Despommier,
In TWIP #33, Dr Despommier said that certain parasites do not need receptors to enter cells, while Dr Racaniello then said that all viruses require a receptor for entry. I might be wro... Read More

Having discussed fulfilling Koch's postulates using culture methods in part 1, this blog post briefly discusses the newer molecular techniques that scientists can use to provide evidence for a disease being caused by a specific organism. Read More
A brief introduction to how scientists prove that an infectious agent is a cause of disease. It discusses Koch's postulates using the imaginary disease chocolatitis and the imaginary organism Chocolobacter as an example. Read More
This episode: Bacteria and fungi work together to explore new territory!
The genome nucleotide sequence has been determined of the bacterium GFAJ-1, which has been suggested to survive in high levels of arsenic and in fact incorporate arsenic into macromolecules. The sequence does not address the controversy over whether the bacterium can utilize arsenic. I suppose t... 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
