The "Do It Yourself" biology movement is growing among real scientists and citizen scientists in homegrown or garage-based labs around the U.S. As this NPR piece reports "they're studying things like DNA and E. coli bacteria in home laboratories. And for now, the industry is largely unregulated.... Read More
A eukaryote without a mitochondrion, and using a phage enzyme to eliminate intracellular bacteria are two topics discussed by the TWiMers on this episode.

A strong argument that the novel human retrovirus XMRV is not a laboratory contaminant is the the finding that viral DNA is integrated in chromosomal DNA of prostate tumors. Why does this result constitute such strong proof of viral infection?
Establishment of an integrated copy of the viral ... Read More

Individual proteins, and individual translated exons within these proteins, are composed of multiple internested viral protein fragments. This is illustrated for the translated exons of DISC1 , where the different viral contributions are colour coded for each virus or phage. Read More

Darrick and Scott write:
Hello Professor Racaniello,
We are two graduate students from the University of Guelph in Canada studying oncogenic sheep betaretroviruses and we are big fans of the show. Part of the reason we like the show so much is that we can use ... Read More
While almost every lab has a small toolbox with some screwdrivers, pliers, and such, here are some tools that may not have obvious utility at the bench, but could make your life easier. Jode Plank, a Postdoctoral Fellow studying DNA repair at the University of California at Davis shares some of ... Read More
Tom talks with Vincent about viral central nervous system infections of global importance, Ebola virus, and running the fastest marathon dressed as a doctor.

The US Food and Drug Administration does not want Rotarix, the rotavirus vaccine, to be used because it contains porcine circovirus 1 DNA. If complete copies of the circovirus genome were present, would they constitute a potential threat to recipients? Put another way, is circovirus DNA infectio... Read More
