Larry Aidem, President & CEO, Sundance Channel announced today that the network will participate in the NBC Universal weeklong programming initiative "Green is Universal."

As part of NBC Universal's unprecedented corporate-wide focus on environmental issues, Sundance Channel will reprise its popular series "It's Not Easy Being Green" and "Big Ideas for a Small Planet" each night beginning at 8pm e/p from November 4 through 10 as well as broadcast its regularly scheduled destination THE GREEN on Tuesday November 6 at 9pm e/p. Sundance Channel is a venture of NBC Universal, CBS and Robert Redford.

Gold really does make you feel better, and not just because you can buy things to make misery more tolerable. Scientists at Duke University Medical Center say new insight into the healing properties of gold may renew interest in gold salts as a treatment for rheumatoid arthritis and other inflammatory diseases.

Physicians first used injections of gold salts in the early 1900s to ease the pain and swelling associated with arthritis. But treatment came at a high cost: The shots took months to take effect and side effects included rashes, mouth sores, kidney damage and occasionally, problems with the bone marrow’s ability to make new blood cells.

Are elections decided by looks? A Princeton University study says even a split-second glance at two candidates' faces is often enough to determine which one will win an election.

Princeton psychologist Alexander Todorov has demonstrated that quick facial judgments can accurately predict real-world election returns. Todorov has taken some of his previous research that showed that people unconsciously judge the competence of an unfamiliar face within a tenth of a second, and he has moved it to the political arena.

His lab tests show that a rapid appraisal of the relative competence of two candidates' faces was sufficient to predict the winner in about 70 percent of the races for U.S. senator and state governor in the 2006 elections.

A new global study revealed that 40 percent of men and 30 percent of women are overweight, while 24 percent of men and 27 percent of women are obese, researchers reported in Circulation: Journal of the American Heart Association.

In the study, 168,159 people (69,409 men, 98,750 women) from 18 to 80 years old (average age 48) in 63 countries across five continents were evaluated by their primary care physicians.

"This is the largest study to assess the frequency of adiposity (body fat) in the clinic, providing a snapshot of patients worldwide," said study lead author Beverley Balkau, Ph.D., director of research at INSERM in Villejuif, France. (INSERM is the French equivalent of the U.S.

Cilia, tail-like projections found on the surface of cells, are perhaps best known as molecular flippers that help cells move around. Recently, researchers have found that cilia are important for many other biological processes, including three of our five senses: vision, hearing, and smell (ciliopathies are often characterized by loss or deficiency in these senses). “That leaves two unexplored possibilities,” says Katsanis. “Taste and touch; we tried touch.”

Humans and genetically engineered mice lacking functional cilia respond more slowly to physical sensations such as exposure to hot water or a sharp poke with a stick.

Human activities are releasing carbon dioxide faster than ever, while the natural processes that normally slow its build up in the atmosphere appear to be weakening, according to a new report. The report states that “together, these effects characterize a carbon cycle that is generating stronger-than-expected climate forcing sooner than expected.”

Between 2000 to 2006, human activities such as burning fossil fuels, manufacturing cement, and tropical deforestation contributed an average of 4.1 billion metric tons of carbon to the atmosphere each year, yielding an annual growth rate for atmospheric carbon dioxide of 1.93 parts per million (ppm). “This is the highest since the beginning of continuous monitoring in 1959,” states the report.
