Dear Vincent and his fellow TWIMsters,
Tom talks with Vincent about viral central nervous system infections of global importance, Ebola virus, and running the fastest marathon dressed as a doctor.
One of the basic requirements of evolution is variation in a population upon which selection can act. One of the sources of variation is mutation in DNA. These changes may or may not be reflected in the ensuing amino acid sequence of a protein. This exercise explores the additive effects of m... Read More
Developing tricks and tools to keep their enzymes in order is one way thermophiles survive. They also use techniques to keep their DNA from falling apart under intense heat. Like proteins, the parts of the long, spiral ladder-shaped DNA molecule start to unravel and break apart under high hea... Read More
The Koala retrovirus (KoRV) continues to spread within Australia, according to results of a new analysis of a larger sample size from a wider geographical range than was previously studied. Read More

All mammalian genomes contain genes encoding Apobec proteins. Several members of this protein family (the name stands for apolipoprotein B mRNA editing complex) are induced by interferon and are intrinsic antiretroviral proteins. Apobec proteins inhibit the replication of XMRV, a new human retro... Read More
Thirty years ago this month I arrived in the Department of Microbiology at Columbia University’s College of Physicians and Surgeons (P&S) to start my own laboratory. Thirty is not only a multiple of ten (which we tend to celebrate), but also a long time to be at one place. It’s clearly time to r... Read More
The Royal Society, founded in London in 1660 and one of the world's oldest scientific institutions, is marking the start of its 350th year by putting 60 of its most memorable research papers online. Several of these documents include papers by Sir Isaac Newton, Benjamin Franklin, and even Antoni... Read More
You have the best podcast on the web, hands down. I use your TWiP episodes in both my undergraduate and graduate classes.
I've recently seen a family in Hawaii with recurrent pathogenic Blastocystis hominis and Dientamoeba fragilis a... Read More
Merry Youle of Small Things Considered fame has a new post on the site that looks at the Acidianus two-tailed virus.
"Why two tails? Why such long tails? The researchers note that ATV is the only virus of an acidophilic hyperthermophile known to lyse its host, albeit only under st... Read More
