A newly discovered ability for people to taste fat could hold the key to reducing obesity, Deakin University health researchers believe.

Deakin researchers Dr Russell Keast and PhD student Jessica Stewart, working with colleagues at the University of Adelaide, CSIRO, and Massey University (New Zealand), have found that humans can detect a sixth taste -- fat. They also found that people with a high sensitivity to the taste of fat tended to eat less fatty foods and were less likely to be overweight. The results of their research are published in the latest issue of the British Journal of Nutrition.

Recently NASA crashed two spacecraft into the moon and orbiters scanned the lunar surface for telltale light signatures—all to confirm the rocky body isn't bone dry after all.

But, it turns out, solid evidence for water on the moon was under our noses the whole time.

Tiny amounts of water have been found in some of the famous moon rocks brought back to Earth by the Apollo astronauts, scientists announced last Wednesday. (Related: "Apollo 11 at 40: Facts, Myths, Photos, and More.")

A team of scientists has discovered that the drastic decline in Arctic musk ox populations that began roughly 12,000 years ago was due to a warming climate rather than to human hunting.

"This is the first study to use ancient musk ox DNA collected from across the animal's former geographic range to test for human impacts on musk ox populations," said Beth Shapiro, the Shaffer Career Development assistant professor of biology at Penn State University and one of the team's leaders. "We found that, although human and musk ox populations overlapped in many regions across the globe, humans probably were not responsible for the decline and eventual extinction of musk oxen across much of their former range."

With The Cove movie winning the 2010 Oscar for best documentary Sunday night, residents of the fishing village made famous in the movie are voicing their disappointment, calling the film inaccurate and intolerant of other cultures.

The Cove's makers and distributors counter that the movie won the Oscar because it was well made and worth seeing, and that the Oscar nod highlights people's concerns about the controversial practice at the heart of the movie—dolphin hunting.

Every year on the first of September, at a cove in a small town called Taiji on the southeast coast of Japan's Honshu Island, a new fishing season begins: the dolphin season.
