Nobel Prize-winning scientist F. Sherwood Rowland died from complications of Parkinson's on Saturday at his home in California. The 84-year-old chemist was considered a pioneer of research about the ozone and the effects of chloroflourocarbons. Rowland's first paper on the subject was discounted by other scientists when it was published in the 1970s, but he won a Nobel Prize for chemistry for his work in 1995. The research helped spread recognition of the depleting ozone layer and influenced restrictions on chloroflourocarbons. "(Rowland) showed me that if we believe in the science ... we should speak out when we feel it's important for society to change," said Mario Molina, Rowland's student and a joint Nobel winner.
