    Hello Kitty! or Don't Eat Me, I Study Genetics!

    Genetics textbooks abound with stories of European royalty and the hazards of having children after you've married one of your cousins. It struck me as an interesting parallel that the lion is such a popular symbol in so many royal coats of arms. Like the royal families of Europe, certain lion populations have also suffered from a few too many...

    Spontaneous human combustion and the chemistry of ghosts

    When purified, it glows with an unearthly light. You can't go "chemical free" and try to escape it. It's part of our bones and it forms the backbone of our DNA. A tool for good, a tool of war, essential for gardening, and infamous as a pesticide; phosphorus is truly an amazing element. Amazing too, are the stories about it's...

    MicrobeWorld: what have you done?

    For the record: Chlamydia is NOT a virus. I am bummed. I like the little MicrobeWorld radio broadcasts, and the video podcasts are even more fun. But I was perusing the archives and I found this:...

    Why I love Nature podcasts

    Got DNA sequencing problems? Who ya gonna call?

    Why the ABRF of course! I spend a fair amount time every summer giving workshops for college and high-school teachers on genomics and bioinformatics. One of the things that always surprises them, is the amount of lab work that's carried out by people working in shared, or core lab facilities. For example, if I was working at a research university...

    Gene therapy with AAV: too risky for a cure?

    Many medical conditions today are treated but never cured. Imagine, a child with a genetic disease like juvenile diabetes or hemophilia. This child will be taking expensive medications for their entire lives. In the case of some diseases the cost of the medications might be more than child or their parents can ever hope to earn in their lifetimes, much...

    Careers in biotechnology, part I.

    What do people in biotechnology do on the job? What can students do with a science degree once they've finished college? Some answers can be found at the "Life Sciences Central web site. Created by the Workforce Development Council of Seattle-King County, this is a wonderful resource for anyone who's considering biotechnology for a potential career. My favorite part of...

    A great interview with Joe Felsenstein

    If you've ever looked at an evolutionary tree, contemplated phylogeny, cladistics, or the like, you're probably aware that Joe Felsenstein is one of the leaders of the pack....

    Plants that make crystals that look like plants

    It's a crystalline botanical fashion show.

    Informed Consent and "An Inconvenient Truth"

    I recently completed a long trip out-of-town, giving a presentation at a Bio-Link conference in Berkeley, and teaching a couple of bioinformatics classes at the University of Texas, through the National Science Foundation's Chautauqua program. The Human Subjects Protection Course Before I left town, I had to take a class on how to treat human subjects. It seems strange, in...
