Uc Science Today

This week on Science Today. Have some researchers underestimated the amount of methane emitted into the atmosphere? According to physicist Marc Fisher of the Berkeley Lab, they may have, at least in the San Francisco Bay Area. "We found that emissions are roughly one and a half to two times the emissions expected based on inventory estimates, counting how many landfills, how many cows, how many wastewater treatment plants, how many different things that might emit methane." Because methane is a very potent greenhouse gas, Fisher says their finding calls for better management of pollutant sources like landfills to reduce its contribution. And at UC Davis, we learned how sometimes in medicine, there are compounds that are found to be good for one thing, but not so great for another. Like in the case of NSAIDs, a class of anti-inflammatory drugs, including ibuprofen. Aldrin Gomes explains how NSAIDs are known to be linked to an increased risk of heart disease and stroke, but he and his colleagues have found
