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
This episode: Bacteria have effects on brain development!
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

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
