Science briefs: Less pollution may mean more living
By Los Angeles Times December 08, 2012, 05:03 PMA new study links even small reductions in fine particle air pollution to increased life expectancy. Researchers who compared data from 545 U.S. counties found that a drop in fine particulate matter, known as PM2.5, between 2000 and 2007 corresponded with an average rise in life expectancy of 0.35 of a year. The study, led by researchers at the Harvard School of Public Health, is described as the largest to date to find public health benefits from ongoing reductions in U.S. air pollution levels.

A prickly sort for certain
By Los Angeles Times November 17, 2012, 04:10 PMScientists in Alberta have identified a new type of horned dinosaur that looked like triceratops but lived 15 million years earlier. Called xenoceratops foremostensis, it was a 2-ton vegetarian that flourished 80 million years ago, making it the oldest known large-bodied horned dinosaur to be found in Canada. Fossils of xenoceratops were first collected in 1958, but were left unidentified at the Canadian Museum of Nature in Ottawa. Scientists working on a larger project, the Southern Alberta Dinosaur Project, have identified about 10 new dinosaurs, including xenoceratops.
