Kyle, 27, has spent most of his life in the groves, which have been in the family since his great-grandfather's day. His first memories are of riding a tractor beneath mile after mile of rich, dark green foliage dappled with orange and yellow. For Kyle and his brother, punishment for misbehavior as teens meant picking fruit for an entire day. "I worked all day and hadn't even filled a tub three-fourths full," Kyle recalls, noting that a good picker can fill three or four tubs, which hold 90 lb. each, in an eight-hour...
...wasn't until 2003 that anyone experimented with DNA methylation quite as dramatically as Duke University oncologist Randy Jirtle and one of his postdoctoral students, Robert Waterland, did. That year, they conducted an elegant experiment on mice with a uniquely regulated agouti gene - a gene that gives mice yellow coats and a propensity for obesity and diabetes when expressed continuously. Jirtle's team fed one group of pregnant agouti mice a diet rich in B vitamins (folic acid and vitamin B12). Another group of genetically identical pregnant agouti mice got no such prenatal nutrition...
...third-party workers caused a rupture in a section of pipeline near the city of Weinan, according to a China National Petroleum statement. A government spokesperson for Weinan, a Shaanxi city along the Wei river, says that as of Jan. 4 no diesel from the leak had reached the Yellow river, about 62 miles (100 km) to the east. But some state media outlets said Monday that the fuel has already reached the Yellow river...
...Yellow river is considered "moderately polluted," according to the environmental ministry. A survey released in 2008 by the Yellow River Conservancy Committee, a Ministry of Water Resources-affiliated environmental organization, found that water in one-third of the river and its tributaries contained water unsuitable for industrial or agricultural use. More than 4 billion tons of sewage had been dumped into the river in 2006, according to a report by the state-run Xinhua news service...
...While China's air pollution woes are literally more visible and receive more attention, water pollution is generally believed to be the country's more pressing environmental problem. The 3,395-mile (5,464 km) Yellow river, known as the mother river for its role in sustaining early Chinese civilization, has an iconic role in China, and a threat to it will draw attention the country's water woes in a way that few other Chinese rivers can. As hundreds of workers race to prevent its already tainted waters from absorbing a new flood of befouling chemicals, it serves...
