Dinosaur Extinction Asteroid
At the end of the Cretaceous, 65 million years ago, not only did the dinosaurs disappear completely, but so did flying reptiles (pterosaurs), and marine reptiles (ichthyosaurs and plesiosaurs).

The Origin of Teflon
The slipperiest stuff known to man, Teflon has made a tremendous impact on the world. Invented by accident in 1938, it has gone on to become a substance in all kinds of household items. Created by mistake, PTFE (poly-tetra-fluoro-ethylene) is a long chain carbon polymer surrounded by fluoride atoms. The fluoride atoms fully enclose the carbon chain so that it can't react with other molecules. It wasn't until 1944 that the name "Teflon" became trademarked. Dr. Kiki gives us the skinny in this

What is a Meteor? Video answers the question: What is a Meteor? A meteorite is a natural object originating in outer space that survives an impact with the Earth's surface. While in space it is called a meteoroid. When it enters the atmosphere, impact pressure causes the body to heat up and emit light, thus forming a fireball, also known as a meteor or shooting star. Very bright meteorites are called fireballs. On very rare occasions meteorites hit t

Toxic: Garbage Island
For years we've been reading about a patch of garbage the size of Texas floating in the middle of the Pacific Ocean, ingeniously dubbed the Great Pacific Garbage Patch. Basically, any trash that gets dumped in the water rides the currents to this one spot and joins an ever-increasing flotilla of garbage. For all the breathless accounts of the mess and its impact on the area's sealife, however, no one seemed to have a picture of the buildup.
In order to sate our own curiosit
