Have you ever wondered what kinds of viruses can be found in human waste? Mya Breitbart and team have been sequencing nucleic acids from fecal samples in order to find out. You might expect that we’d find viruses that infect humans or viruses that infect the bacteria in our gut. I wouldn’t have expected to…

I’m in Berkeley right now at the annual Bio-Link Summer Fellows forum. We’re getting to hear talks from people in the biotech industry, listen to enthusiastic instructors describe their biotech programs and ideas, and try out new educational materials. Yesterday, two speakers (Damon Tighe and Jason Baumohl) from the Joint Genome Institute in Walnut Creek,…

I got my copy of “A short guide to the human genome” by Stewart Scherer today from Cold Spring Harbor Laboratory Press (2008, ISBN 978-087969791-4). Usually, I would wait until after I’ve read a book to write a review, but this book doesn’t require that kind of study. As soon I skimmed through it and…

Dave Robinson and Joann Lau from Bellarmine College in Kentucky are going to be describing their student project in a free webinar next Friday, May 16th. Their students clone GAPDH (Glyceraldehyde 3-Phosphate Dehydrogenase) genes from new plants, assemble the DNA sequences, and submit them to the NCBI. Here’s an example. Plus, since GAPDH is a…

A potential link between lung cancer and human papilloma virus may make parents even more glad about vaccinating their children with Gardasil®. Not only are the children protected against viruses that commonly cause cervical cancer, they may be protected against some forms of lung cancer as well. The April 25th version of Nature News reports…

Bill Gates, Eric Lander, Maynard Olson, Leena Peltonen, and George Church fielded questions last night at a fascinating panel discussion on personal genomics at the University of Washington. We were fortunate to be in the audience. I’ll share some of the questions and answers, in some cases shortened and paraphrased.

One of my favorite web 2.0 technologies is the webinar. When you work at a company and not a University, with constant seminars, it gets a bit harder to hop on a bus and travel across town to learn about new things. Webinars are a good way to fill that gap. I grab my coffee…

In the class that I’m teaching, we found that several PCR products, amplified from the 16S ribosomal RNA genes from bacterial isolates, contain a mixed base in one or more positions. We picked samples where the mixed bases were located in high quality regions of the sequence (Q >40), and determined that the mixed bases…

I know some of you enjoy looking at data and seeing if you can figure out what’s going on. For this Friday’s puzzler, I’m going to send you to FinchTalk, our company blog, to take a look at lots of data from a resequencing experiment that was done to look for SNPs and count alleles.…

Is it real or is it April Fools?
