The Obama administration today announced that it is scuttling its plans to install missile defense equipment in countries in Eastern Europe. The change of heart happened, to a large extent, because of vocal opposition and overt threats of military response from Russia.
Why the opposition? The New York Times notes that Russian "Prime Minister Vladimir V. Putin [...] had repeatedly assailed the antimissile system as a grievous threat to Russia’s security."1
So we return to my earlier question: how would a defensive missile interceptor system, which cannot be used for attacks, pose a threat to Russia's security?
In that Mr. Putin believes that Russia's security requirements include the ability to bomb into oblivion parts of Poland, the Czech Republic, and other former Soviet countries, if and when he so desires. And to do so unencumbered by American defense installations. That is all.

Nintendo will be selling one for the Wii, under the name "Wii Vitality Sensor." They haven't yet figured what to use it for, though. (Note: You can't do anything physically active while wearing the probe, or you'll get a noisy signal!)

Some students at the University of Michigan put together an incredible musical parody of the Harry Potter series, and it's now available for viewing on YouTube (playlist with 23 videos, running time about 2h45m). They've been featured on NPR in Michigan.
The production is unbelievably funny and well done - watch it when you have a few hours of free time!
Hat tip to Reyzl G. for finding this.
A red-tailed hawk takes refuge from the rain on scaffolding on Perkins Hall, on Oxford St. Here's another picture.
Apparently this is one of a few hawks that reside on Oxford St. near the Natural History Museum; see the Campus Nature Watch section here and here.
Thanks to Kobi Gal for letting me use his camera.
