Countries with nuclear power plants have spent decades figuring out the proper place to bury nuclear waste and will spend decades more digging and filling 500 meter holes in the earth where it will live. One of the most the crucial pieces in safely burying the waste is keeping accurate records of where the waste is buried so that future generations don't accidentally dig it up.

The solution to that problem may lie in a $30,000 hard disk, made of an indestructible combination of sapphire and platinum that claims to be durable enough to last for up to one million years. It was designed by a diverse team of scientists, anthropologists, archeologists, artists, archivists and linguists who worked to build something that would last, but could also be understood by people thousands of years from now.

This hard disk is different from the type of external hard drive that you would save your documents and music on, and not just because of how long it lasts and expensive it is. Unlike a

Researchers at UCLA have created a new transparent polymer based solar cell that may eventually turn buildings, cars and smart phones into energy generating solar cells.

Every 15 minutes the Earth is hit with enough sunlight to provide energy for the entire planet - for a whole year! The goal is to harness that energy at the highest efficiency possible.

By absorbing infrared light instead of visible light, like current solar cells, the polymer solar cells are nearly 70 percent transparent to the human eye. So they can be applied to clear surfaces that were previously unable to house solar cells.

That means they could be applied to portable gadgets like smart phones, tablets and MP3 players. They could also be applied to the top of your car or to the side of skyscrapers.

The lead researchers from UCLA, Professors Yang Yang and Paul Weiss, joined us from their office at UCLA to discuss the breakthrough.

Even though MaKey MaKey was designed by two Ph.D candidates from MIT, their goal was to make something for the kindergartener in all of us.

It's a device that allows you to turn anything that conducts electricity into a functional computer key. It looks like it might be difficult to hook up, but it's actually very simple - so simple a 4-year old was able to do it without trouble.

The team, Jay Silver and Eric Rosenbaum, have dedicated themselves to designing easy-to-use invention kits. "We believe that everyone is creative, inventive, and imaginative. We believe that everyone can create the future and change the world."

Even the most jaded technology enthusiast can't help but chuckle when they hook up a banana to an alligator clip and use it to scroll through their computer. But the beauty is that it's up to you to decide what to turn into a key.

In Jay and Eric's video they play Mario Bros. with Play-Doh, Dance Dance Revolution with buckets or water, the piano with a staircase, and
