Memorial to Martin Luther King Jr. opening on National Mall

The morning sun that came up over Washington's Tidal Basin on Monday illuminated a new memorial opening to the public for the first time: a plaza and statue honoring the late civil rights leader Martin Luther King Jr.

President Barack Obama is scheduled to dedicate the site on Sunday, but the media and visitors were allowed to take part in a "soft" preview as construction crews complete their final touches.

"I feel like I'm standing on holy ground," said Donnie Simons, nearly overcome with emotion at the sight of the granite portrayal of King.

Oldest Fossils on Earth Suggestive of Life on Mars

A microbial bacteria fossil discovered by Australian resesarchers may be proof of life on Earth before oxygen 3.4 billion years ago.  The Strelley Pool Formation in Western Australia houses stromatolites which have been preserved there.  Stromatolies are structures that are formed in shallow water through the trapping, binding, and cementing sedimentary grains using biofilms and microorganisms.   

The researchers said that life on Earth was born after the Late Heavy Bombardment, when waves of asteroids slammed into the planet, heating its surface and boiling its oceans.  The bombardment ended 3.85 billion years ago and took out budding life

How to Turn TV Watching into a Workout

The bad news is out. Too much TV time can shorten your lifespan. However, if you aren't ready to break up with your Tivo just yet, there are still ways to sneak in some activity while you're watching your favorite shows even if it's just during commercial breaks.
