The `radical` ways sunlight builds bigger molecules in the atmosphere
(PHYSorg.com Chemistry)

With summer approaching, `sea and sun` might conjure up images of a beach trip. But for scientists, the interactions of the two have big implications for the climate and for the formation of tiny droplets, or aerosols, that lead to clouds. In ACS Central Science, researchers demonstrate that sunlight can cause certain molecules at the ocean`s surface to activate others, resulting in larger molecules that could affect the atmosphere.
