    Metagenomics: a summer internship position and post-doc search

    Hey students: if you are looking for a summer internship in marine metagenomics and you can get your application together before June 16th, Jonathan Eisen posted information about an open position on his blog. It also looks like he's looking for post-docs (see the side bar on the right of this page.)...

    Pepper viruses populate people poop

    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 learn the result that they...

    Flash animations of Sanger DNA Sequencing

    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, CA, gave a fun talk...

    Playing in the dirt: metagenomics on the JHU campus

    We have lots of DNA samples from bacteria that were isolated from dirt. Now it's time to our own metagenomics project and figure out what they are. Our class project is on a much smaller scale than the honeybee metagenomics project that I wrote about yesterday, but we're using many of the same principles....

    Sequencing the campus at the Johns Hopkins University

    A few years ago, the General Biology students at the Johns Hopkins University began to interrogate the unseen world. During this semester-long project, they study the ecosystems of the Homewood campus, and engage in novel research by exploring the microbial ecosystems in different sections of the campus. Biology lab students gather environmental samples from different campus ecosystems, isolate DNA, amplify...
