"Historically, scientists have focused on breeding useful traits such as disease resistance from African rice into Asian rice. Now the focus is on the reverse -- using African rice as the basic crop and improving it with Asian genes. "African rice was initially ignored by mainstream research," said Koichi Futakuchi, a scientist at Africa Rice Center (AfricaRice) in a statement."

"The first monogamous amphibian has been discovered living in the rainforest of South America."

Your principal incentive to recycle? That one's a no-brainer: the environment, of course. But, it doesn't just have to be a green act of good will; it can add a little extra cash to your wallet as well. Recycling for money sure won't make you a millionaire, but these days every penny counts. So, cash in on your good conscience with these items.

"Scientists have found vast underwater plumes of oil, one 10 miles (16km) long and a mile wide, in the Gulf of Mexico, following last month's rig disaster."

"Cells grown in microgravity generate problematic proteins (absent in normal stem cells) that play a role in bone deterioration."

How does a lens form an image? See how light rays are refracted by a lens. Watch how the image changes when you adjust the focal length of the lens, move the object, move the lens, or move the screen.

William Li presents a new way to think about cancer treatment: angiogenesis, targeting the blood vessels that feed a tumor. The crucial first (and best) step: Eating cancer-fighting foods that beat cancer at its own game.

In this three-part documentary series, Professor Jim Al-Khalili tells the story of one of the greatest scientific discoveries ever: that the material world is made up of atoms.

In a perfect world, you could enjoy great sound by installing just four full-range speakers - one in each corner of your car. In the real world, things aren't quite that easy. Full-ranges simply aren't up to the task of accurately reproducing the entire music spectrum. That's why top-notch systems employ two or more component speakers - like a woofer and tweeter - per channel. Each component is designed to reproduce a specific range of frequencies, and together they can cover the entire music spectrum accurately.\n\nA complication arises, however, since source components such as CD players deliver all of these frequencies - low, high, and in between - as a single music signal. This is where crossovers come in. A crossover divides the music signal into frequency bands that are compatible with the different types of component speakers.

"Graphene, a one-atom-thick layer of graphitic carbon, has great potential to make electronic devices such as radios, computers and phones faster and smaller. But its unique properties have also led to difficulties in integrating the material into such devices."
