Mind control and Dinosaurs

Today I learned that researchers at the university of Washington (or maybe Washington university) successfully used mind control. They had themselves hooked up to EEG and magnetic something or others and, from across campus, one scientist made the other one involuntarily press a trigger button while playing a video game. The transmitted the signal over the internet. Pretty small stuff, but cool.

I also learned, from a children's book, that's the Jurassic period was earlier than the Cretaceous period, that the Diplodocus ate rocks to help digest leaves rather than chewing them before swallowing, that the Sauroposeidon (this thing has gotta have something to do with water, right?) was as tall as a six-story building, that the Apatosaurus was formerly known as the Brontosaurus, and that the Argentinosaurus was one of the largest land animals to have ever lived, at about 130 feet long and 200,000 pounds.
