To the TWiVerati Intelligencia,
Each week you begin your show with the tagline, "This Week in Virology: The podcast about viruses, the kind that make you sick."
I recognize that viruses have been responsible for some of the biggest epidemic... Read More
The figure for the number of prokaryotic cells on the planet, roughly 5x1030, is considerably greater than that of the estimated number of stars in the firmaments (3x1023). These two numbers have one thing in common: they both grew hugely and rather suddenly in recent human history.

Whether or not the retrovirus XMRV is a human pathogen has been debated since the virus was first described in 2006. The answer is now clear: the results of Blood XMRV Scientific Research Group, along with a partial retraction of the 2009 Science paper describing identification of the retrovirus... Read More
Life in a high-pressured environment with practically nothing to eat might be ok for high-fashion models, but it’s an unlikely lifestyle choice for a single cell whose usual overriding goal is to become two cells. Yet the largest living ecosystem on Earth—the deep biosphere—is comprised of micro... Read More
Today is World Tuberculosis Day.
"World TB Day, 24 March 2009, is about celebrating the lives and stories of people affected by TB: women, men and children who have taken TB treatment; nurses; doctors; researchers; community workers--anyone who has contributed towards the global fight agains... Read More
The hunt continues for novel antiviral agents especially against the pandemic H1N1 virus. In this article, a drug that has been used to fight HIV infection and vesicular stomatitis now appears to have the potential to block influenzavirus infection by inhibiting neuraminidase. This may be yet ... Read More
The American Society for Microbiology Committee on K-12 Education publishes peer-reviewed resources that convey important scientific concepts from the microbial world, such as microbial processes, methods used to study microorganisms and other general science topics. The activities are student-c... 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
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
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
