Secondary organic aerosols, tiny “tar balls” resulting from combustion products of internal combustion engines that can encapsulate gaseous pollutants, have been identified as a danger to health. Diesel fuel oil seems to be more responsible for these aerosols than gasoline which is counter to normal thinking on the subject.

So why do they not stick? Researchers at the Smithsonian Tropical Research Institute and University of Costa Rica studying why spiders do not stick to their own sticky webs have discovered that a spider’s legs are protected by a covering of branching hairs and by a non-stick chemical coating. Their results are published online in the journal, Naturwissenschaften. They also observed that spiders carefully move their legs in ways that minimize adhesive forces as they push against their sticky silk lines hundreds to thousands of times during the construction of each orb.

Examples are clouds, and air pollution such as smog and smoke In a suburb of smoggy Los Angeles, University of California experts are providing a likely answer to a sticky scientific problem. A growing body of research has shown that computer models used by federal regulators for decades significantly underestimate the quantity of organic aerosols, a major component of dangerous smog and the largest unknown in climate-change calculations. Organic aerosols may act as a transport vehicle of organics and other water insoluble compounds into the atmosphere.
