You can get a jump on the Darwin Day festivities. Once again the Alliance for Science is sponsoring an essay contest for Darwin Day. If you download their suggestions for good essay writing, you can get your essay done over winter break and have a good crack at winning on those cash prizes! The Alliance…

This is a fun puzzle. The pink molecule is a protein and the other molecule is a nucleic acid.

As many of you know, I’m a big fan of do-it-yourself biology. Digital biology, the field that I write about, is particularly well-suited to this kind of fun and exploration. Last week, I wrote some instructions for making a phylogenetic tree from mitochondrial genomes. This week, we’ll continue our analysis.

Students at Soldan International High School are participating in an amazing experiment and breaking ground that most science teachers fear to tread. Soldan students, along with hundreds of thousands of other people, are participating in the National Geographic’s Genographic Project. Through this project, students send in cheek swabs, DNA is isolated from the cheek cells,…

Last year I wrote about an experiment where I compared a human mitochondrial DNA sequence to primate sequences in the GenBank. Since I wanted to know about the differences between humans, gorillas, and chimps, I used the Entrez query ‘Great Apes’ to limit my search to a set of sequences in the PopSet database that…

Two protein structures from an avian influenza virus are shown below. One form of the protein makes influenza virus resistant to Oseltamivir (Tamiflu®) Don’t worry, these proteins aren’t from H5N1, but they do come from a related influenza virus that also infects birds. technorati tags: molecular models, protein structures, influenza, bioinformatics, Cn3D

One of the places that I’ve always wanted to visit in Portland, OR, is Powell’s City of Books. Powell’s is the kind of bookstore that people in Seattle discuss in the same reverent tones that they use when they’re describing Cody’s in Berkeley or City Light in San Francisco. It’s not just a bookstore. It’s…

Thanks to Steven Colbert you can hear about DNA directly from Dr. Spencer Wells from the National Genographic Project. I read about this video in the GenomeWeb Daily Scan and had to check it out. Who would have thought scientists could be so funny?

Not content with his recent exploits in human experimentation and cavorting with Plosites in San Francisco, Professor Steve Steve jetted across the country once again, last week, hitting both both Blacksburg, VA and Seattle, WA, and creating pandemonium wherever he went. And raising the question – how does he get back and forth across the…

By now, many of you have probably seen the the new BLAST web interface at the NCBI. There are many good things that I can say about it, but there are a few others that caught me by surprise during my last couple of classes. tags: blast, BLAST tutorial, science education
