Humans and garbage .. after you watch these videos, you'll ask yourself if humans can do anything -- even go into space -- without creating a huge trail of garbage? This space garbage is extremely dangerous, too. For example, 10-gram piece of debris can generate a collision force in space equal to the crash of a car traveling at 100 km per hour. Because of our trashy ways, it won't be long until space vehicles cannot leave earth because of the thickening belt of garbage circling planet.
This is a hilarious trailer for the spoof, "The Peeps": a parody of Alfred Peepcock's ... erm, Hitchcock's ... "The Birds." This film documents the biggest marshmallow threat to humanity since the Stay Puft Marshmallow Man.

It has long been known that when exposed to ultraviolent light, fossilized bones and shells -- and even tissues -- will fluoresce, thus rendering undetectable details visible. But this technique has been used mostly to visualize fossilized invertebrates, and inexplicably, has rarely been used to investigate hidden structures in most vertebrate fossils. But a team of paleontologists recently studied the Microraptor gui holotype using UV light.
