*Three-year series of scientific missions from Arctic to Antarctic produces new views of atmospheric chemistry*
A three-year series of research flights from the Arctic to the Antarctic has successfully produced an unprecedented portrait of greenhouse gases and particles in the atmosphere.
The far-reaching field project, known as HIPPO, ends this week, and has enabled researchers to generate the first detailed mapping of the global distribution of gases and particles that affect Earth’s climate. (more…)
EAST LANSING, Mich. — Besides helping each other plant and harvest, rural Chinese neighbors also influence each other’s environmental behavior – farmers are more likely to reenroll their land in a conservation program if they talk to their neighbors about it.
Scientists from Michigan State University’s Center for Systems Integration and Sustainability used a simulation model to study the amount of land farmers in the Wolong Nature Reserve in southwestern China re-enrolled in the Grain-to-Green Program, which aims to reduce soil erosion by converting sloping cropland to forest or grassland. Farmers receive an annual payment of either 5,000 pounds of grain or $498 for each 2.5 acres enrolled in the program. In 2005, this was about 8 percent of the farmers’ income. (more…)
Where do turtles belong on the evolutionary tree? For decades, the mystery has proven as tough to crack as the creatures’ shells. With their body armor and retractable heads, turtles are such unique creatures that scientists have found it difficult to classify the strange animals in terms of their origins and closest relatives.
“We know turtles evolved from a common ancestor along with birds, lizards and snakes about 300 million years ago, but who modern-day turtles are most closely related to is one of the biggest and most controversial questions in the field of systematics,” said Tyler Lyson, a Yale University graduate student who studies the evolutionary relationships between different animal groups.

In 1968, when Su Wei left his family behind and voluntarily joined the millions of urban youth who were being sent by Chinese leader Mao Zedong into the countryside to work the land as part of a “re-education” movement, his spirit was nearly broken.
As part of Mao’s “up to the mountains and down to the villages” campaign, initiated in 1968 to quell civil unrest during the Cultural Revolution, all urban 16-year-olds were commanded to travel to rural villages to be schooled in hard agricultural labor. More than 20 million teenagers were sent to work in the countryside, often devoting more than a decade of their lives to farm labor. Not only did this deprive them of a formal education, but parting from their families was a heart-wrenching experience for most of the youngsters. However, for then 15-year-old Su — now a senior lector in East Asian languages at Yale — leaving life in Guangzhou (Canton) represented an escape from an even more brutal life, and so he set off eagerly for the countryside even before he was required to do so.

Mark Zuckerberg, founder of Facebook Inc., was named Time magazine’s “Person of the Year” today for “creating a new system of exchanging information” and “changing how we all live our lives.”
Zuckerberg, 26, began the world’s largest social-networking site in 2004. The service, with more than 500 million users, has helped people connect with each other and changed definitions of privacy, Time Managing Editor Richard Stengel said in a letter on the magazine’s website. (more…)
COLUMBIA, Mo. – As local online news services become more numerous, discussions regarding their quality and stability have increased as well. Michele McLellan, who served as a 2009-2010 Reynolds Journalism Institute (RJI) Fellow at the University of Missouri, has found dozens of online news sites that are gaining traction. She says it is vital for the future of the news industry to identify these promising sites.
