The chromosomal DNA of several mammals has been found to contain sequences related to the nucleoprotein (N) gene of bornaviruses, enveloped viruses with a negative-strand RNA genome. I am amazed by this finding. How did bornaviral DNA get in our chromosomes, and what is it doing there? Read More
In an ideal world, every PI would be a nurturing and challenging mentor who carefully guides your project and is invested in developing your skills as a scientist. In the real world, however, that kind of leadership can be hard to find.
In any case, one of the most important and useful mental... Read More
Is bacterial DNA contamination in your whole genome amplification kit a problem? For microbiologists it sure is. WGA is a technique where the complete genomic content of a sample is amplified non-specifically and at a single temperature (isothermically). The presence of any contaminating DNA in ... Read More

I spent a week and a half learning metagenomic analysis in Michigan from some awfully smart and pleasant people. Learn more at the link! Read More
In midsummer 1986, five years after starting my poliovirus laboratory at Columbia University, I received a letter from Frederick L. Schaffer, a virologist at the University of California, Berkeley, asking if I would like to have his collection of poliovirus stocks. He was retiring and the sample... Read More
Should you ever visit Cold Spring Harbor Laboratory on Long Island, New York, be sure to go see the food blender that was used to carry out the well known Hershey-Chase experiment. The blender is located in the Szybalski Reading Room of the Carnegie Library. After entering the front door of the ... Read More
Greetings Vincent and Dick,
Hooray for finally mentioning G. pulchrum in episode 62, my most favorite parasite and one worthy of further discussion. As a diagnostic veterinary pathologist, I encounter this spirurid in approximately... Read More
In this post from my microbiology/education blog, I discuss a post on Boing Boing recently that used a video I had made of ice nucleation bacteria. Ice nucleation bacteria are very interesting of course, and I link to the Boing Boing post. In addition, I provide an additional video of students... Read More
Hello Dr Racaniello and Despommier,
I recently saw an article about the paper linked below on Science Daily and thought it might be worth a discussion on TWIP. It is about the possibility of bed bugs being a vector for T. cruzi. I would love to... Read More
Professors, you've discussed this idea before, but I thought you'd enjoy this nice summary from Nature:
Is there such a thing as an obligatorily multicellular prokaryote? Merry Youle of the Small Things Considered blog reviews a recent paper published in the May issue of Applied and Environmental Microbiology that announces the finding of a new subgroup within magnetotactic multicellular prokaryot...
