What are all those tiny little elf-doors scattered throughout the U.S. Capitol?

When you visit the U.S. Capitol building in Washington, D.C. try not to get too caught up in the splendor and instead, look down. Chances are you'll see a tiny little elf-door somewhere along the wall. In fact, they are scattered throughout the U.S. Capitol building but most visitors never notice them. The tiny doors serve as more than just a conversation piece or humorous Reeko's Mad Scientist Lab article. At one time, they served an important function. But we have to look way back in time to understand how those tiny little doors kept the Capitol building safe. The Christmas Eve Capitol fire On Christmas Eve in 1851, a guard (John Jones) was making his rounds through the Capitol building when he noticed a flicker of light

Uh oh. How come this map just released by NASA is glowing RED!!!

NASA just released this satellite image of an eerie red glow over the Midwestern and Eastern United States.  If your reaction was similar to Reeko’s (he threw on his hat and ran to the closet to grab his suitcase), you might think this is a bad thing.  It’s not.  As plants carry out photosynthesis, their chlorophyll also creates a very small amount of fluorescence, a type of radiation.  This radiation is invisible to our eyes but the superhumans at NASA however, have the technology to detect the fluorescence on satellite images and display on this map.  The brighter red areas show where greater amounts of photosynthesis have taken place from 2007 through 2011.
