This was a good read: Birds can see Earth’s magnetic field, and we finally know how that’s possible.

With the Earth’s atmosphere getting warmer, NPR has an article, Is there a ticking time bomb under the Arctic? (The short story is that there’s twice as much carbon in the thawing permafrost as their is in the Earth’s atmosphere.)

Phil Plait on syfy.com has a nice story about a black-hole merger.
“If an alien in a galaxy 65 million light years away is looking at us through a telescope right now, then they are looking at dinosaurs.”
National Geographic has an article titled, Mysterious Particles are Slamming Into the Earth.
This is cool, though I don’t know why people are always picking on Pluto. (It may also need an asterisk stating that Saturn needs to be at an angle like that.)
