So the scientists hypothesized that if they could prevent the chain lengthening by reducing the levels of KASII, they could decrease the likelihood ...Computer-designed molecule to clean up fluorocarbons?
The chemical bond between carbon and fluorine is one of the strongest in nature, and has been both a blessing and a curse in the complex history of fluorocarbons. Now, in a powerful demonstration of the relatively new field of "computational chemistry," researchers at the National I...National Academies Advisory: March 5 lecture on ocean acidification
Most carbon dioxide emissions are absorbed by the ocean, where the gas reacts with seawater to form carbonic acid that can dissolve the shells and skeletons of marine organisms, including corals.
