    viruses:

    A vaccine against lung cancer?

    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 (1) that two viruses, HPV...

    How does a single nucleotide change make influenza virus resistant to a drug?

    Fun with molecular models!

    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...

    Is Alaska preparing for bird flu?

    I'm seeing these things everywhere. Well, okay, maybe not everywhere. But I have seen lots of these in both Fairbanks and Anchorage. Is this a coincidence? This is a hand-sanitizer, with instructions on how to cough safely....

    Hot plants and viruses: the story continues

    Yesterday, both Joshua and I wrote about grasses that grow in the unusually hot soil at Yellowstone National Park. Now, I knew that hot springs bacteria can tolerate high temperatures, but I was really surprised to learn that plants could....

    If you can't stand the heat, get infected!

    Are viral and fungal infections always a bad thing? Maybe not if you're a plant. In fact, if you're a plant trying to grow in the hot (65° C) soils of Yellowstone National Park, you're going to need all the help you can get....

    It's cold and flu season: do you cough safely?

    Watch "Why don't we do it in our sleeves?" and find out how you rank on the safe coughing scale....

    39.5 million people have HIV

    Random thoughts on AIDS and HIV

    Using HIV to prove some points about evolution, part IV

    Did HIV become resistant to Atazanavir because of a genetic change? Was that genetic change inherited? Did HIV evolve? Can we explain why genetic changes at specific sites might help HIV escape the effects of the drug? Let's find out....

    Using HIV to prove some points about evolution, part III

    In which we see the results and come to our own conclusions. If you want to let other people tell you what's right and what's wrong, they will surely do so. Turn on the TV and hordes of happy actors bounce around, only too happy to help you purchase the right deodorant. Open your e-mail and everyone wants to share...

    Using HIV to prove some points about evolution, part II

    Let the experiment begin....

    No, I don't worry about AIDS anymore

    But that hasn't always been true. When I was in college, I had part-time jobs drawing blood from patients in the university hospital and as a phlebotomist at local plasma center. Plus, I was a volunteer EMT on an ambulance crew. Needless to say, I saw plenty of blood. And those were the days when no one wore gloves. We...
