Astronomers using the NASA Spitzer Space Telescopes have discovered buckyballs for the first time in space. These all-carbon molecules are now considered the largest molecule ever discovered in space. A single buckyball is about 1 nanometer across--about three times larger than a water molecule.

Australian/U.K. scientists have identified the molecular material that causes celiac disease in some humans. They hope the discovery will lead to a drug to control the disease that prevents such people from eating gluten-based foods.

The U.S. space agency NASA has produced the world's first map of the height of all Earth's forests. The map will help scientists learn more about the carbon cycle and its affect on our atmosphere.
