    Ebola

    While we're here arguing about creationism and evolution, some of my colleagues are trying to do something about the state of the world: fighting Ebola. (Note: Pardis and her lab, including me, are in the Department of Organismic and Evolutionary Biology. So we can't get away from evolution...

    The White Mountains

    Last weekend I went hiking up Mt. Washington in New Hampshire with some friends. Here are a few shots from the trip. All taken with my point-and-shoot camera, a Fuji F200EXR, since I didn't feel like lugging my DSLR up 4000 vertical feet -- and in some cases it shows. Saco Lake DSCF1404 The...

    What is it with these guys?

    For some reason, these red-coated gentlemen insist on invading our town every April: And they're loud about it, too: The locals always manage to beat them off . . . but come next April I'm sure they'll be back again.

    My challenge challenge challenge

    A member of a forum you regularly reads repeatedly posts challenges in the form of polls, all making exactly the same point. Other members of the forum, fed up with this, challenge the challenge polls with their own, increasingly bizarre polls, which we will call "challenge challenge polls"...

    California by infrared

    On my family vacation I also took along my infrared-modified camera (an old Nikon D70) and shot with that as well. This was somewhat more experimental, since I'm still figuring out what works with IR and what doesn't. Some results: Memorial Church, Stanford University Somewhere near Fort...

    New toy: infrared

    I recently had my old DSLR (a Nikon D70) converted to work as a purely infrared camera. It took some fussing to get the camera and some of my lenses to focus well together, but I got it working and took it out for its first spin over the weekend. This shot (of our town's green) shows the...
