My thoughts on biology, teaching, life, and exploring the living world via the digital one. Only my opinions are represented by these postings, they do not represent the viewpoints of any funding agency or Geospiza, Inc.
I am a microbiologist and molecular biologist turned tenured biotech faculty turned bioinformatics scientist turned entrepreneur. My passion is developing instructional materials for 21st century biology (Geospiza Education).

Which read(s): 1. contain either a SNP (a single nucleotide polymorphism) or a position where different members of a multi-gene family have a different base? C 2. doesn't have any DNA? B 3. is a PCR product? A, B, and C. All of three reads were obtained by sequencing PCR products, generated with the same set of primers. The quality...

The genie is out of the bottle. Personal genomes are not just for Venter and Watson anymore. Three competing companies, 23andme, Decode, and Navigenics are betting that you want to do a little better than reading your horoscopes and playing with tea leaves. They think that you want to know something about your destiny and take control of your future....

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, and genetic markers are used...

The Wired Campus has an interesting article on nursing students at Tacoma Community College. In John Miller's class, the students practice interviewing patients in Second Life. This sort of activity, of course, is one that could be carried out in a classroom, but I can see the advantages of having student interview other "people" who are for the most part,...

Congratulations to George Cachianes (who I've written about before), his amazing students from Abraham Lincoln High School, and collaborators at UCSF! These students, from a public high school no less, placed in the top 6 finalists, along with only one other US team. The other top teams were: Peking University (China), University of Science and Technology (China), University of Paris...

For many years, I had my biotech students do projects where each group of students would analyze their own data, in addition to all of the data gathered by the class. I would draw a table on the white board and each group would enter their data. At the end of the class, all the groups would copy all the...
