China, U.S. at odds on plan to cut emissions
China and the United States took small steps Wednesday toward their shared goal of fighting climate change, but the world's No. 1 and No. 2 carbon emitters remain far apart on a global plan to cut emissions. China's chief climate official Xie Zhenhua said China shouldn't be subject to the same rules for greenhouse gas emissions as the United States and other rich countries, signaling Beijing will oppose any attempt to impose them at next year's world climate conference. "We are in different development stages, we have different historical responsibilities and we have different capacities," Xie said. U.S. special envoy Todd Stern said Washington favors each country deciding what it's capable of doing to help curb climate change.
Study links psych drugs, ER visits
Bad reactions to psychiatric drugs result in nearly 90,000 emergency room visits each yea, with anti-anxiety medicines and sedatives among the most common culprits, a study finds. A drug used in some popular sleeping pills was among the most commonly involved sedatives, especially in adults 65 and older. Most visits were for troublesome side effects or accidental overdoses and almost 1 in 5 resulted in hospitalization. The results are from an analysis of 2009-11 medical records from 63 hospitals. The study was published Wednesday in JAMA Psychiatry.
