— Now that most consumers download and stream their movies and music, more and more CDs and DVDs will end up in landfills or be recycled.

But soon these discarded discs could take on a different role: ...

— The world can emit even less greenhouse gases than previously estimated in order to limit climate change to less than 2°C, a new study shows.

It can also be used as a marker to track the metabolism of new pharmaceutical molecules. Its presence in organic materials is used extensively as basis of the radiocarbon dating method to date archaeological, geological, and hydrogeological samples.— Scientists have created a new structure by encapsulating a single layer of fullerene molecules between two graphene sheets. — A new material with micropores might be a way to fight climate change.Because the ratio of carbon 12 to carbon 14 present in all living organisms is the same, and because the decay rate of carbon 14 is constant, the length of time that has passed since an organism has died can be calculated by comparing the ratio of carbon 12 to carbon 14 in its remains to the known ratio in living organisms. Our Living Language : In the late 1940s, American chemist Willard Libby developed a method for determining when the death of an organism had occurred.He first noted that the cells of all living things contain atoms taken in from the organism's environment, including carbon; all organic compounds contain carbon.
