"In large sections of America's farmland, new strains of weeds are making life miserable for farmers. They've developed resistance to the country's No. 1 weedkiller, Roundup. Now farmers face a choice: Do they go for yet another kill-all-the-weeds chemical, or go back to more complicated, labor-intensive ways of fighting weeds?"
"More than two billion people have gained access to better drinking water sources, such as piped supplies and protected wells, between 1990 and 2010, UN officials said on Tuesday. The figure means the world has met the internationally agreed Millennium Development Goal to halve the proportion of people with no safe drinking water well ahead of a 2015 deadline, UNICEF and the World Health Organization said."
"From its perch in a spacious brand-new headquarters blocks from the White House, the Cato Institute has built on its reputation as a venerable libertarian research center unafraid to cross party lines. Now, however, a rift with one of its founding members — the billionaire conservative Charles Koch — is threatening the institute's identity and independence, its leaders say, and is exposing fault lines over Mr. Koch's aggressive and well-financed brand of Republican politics."
"HAGERSTOWN, Md. -- A 2009 federal study that concluded groundwater contamination from Fort Detrick was unlikely to have harmful health effects was flawed, a national scientific panel said Monday, prompting two U.S. senators to demand a faster cleanup of the Superfund site in Frederick [MD]."

This makes Iowa the first state in the country to pass such a law; Illinois, Indiana, Minnesota, Missouri, Nebraska, New York and Utah are considering them. Undercover investigations, including videos and photographs, are a principal tool used by activists of all stripes to document abuse cases and have led to legislative reforms, prosecutions and even facility closures around the country."
Ice -- on both sea and land, near the poles and at high altitudes -- is connected in a number of ways with changing climate, as both a symptom and a cause. Several news stories about ice melt have come out recently. Charlie Petit at MIT's Knight Science Journalism Tracker has done a bang-up job of summarizing them. So we will save time and effort by linking directly to his work, which will richly reward the climate-curious.
Billionaire Aubrey McClendon CEO of Chesapeake Energy, the nation's second-largest natural gas producer, is an evangelist for "fracking." Is the boom in natural gas a bubble that will go bust as the price of gas itself continues a dizzying fall?
Coltan ore is valuable as a source of niobium and tantalum, metals key to many kinds of electronics. Coltan mining has helped finance war in places like the Democratic Republic of Congo.
