ANN ARBOR, Mich.— Women in their 70s had a longer life expectancy when they exercised and regularly ate fruits and vegetables, a new University of Michigan study found.

“This is the first study to show that the combination of a healthy diet and greater physical activity predict greater survival and that the combination of both positive factors confers lower mortality risk than either factor alone,” said Emily Nicklett, U-M assistant professor of social work.

Nicklett and researchers at The Johns Hopkins University studied the results from 713 women ages 70 to 79 years who participated in the Women’s Health and Aging Studies. (more…)

Black Hole Caught Red-Handed in a Stellar Homicide

PASADENA, Calif. – Astronomers have gathered the most direct evidence yet of a supermassive black hole shredding a star that wandered too close. NASA’s Galaxy Evolution Explorer, a space-based observatory, and the Pan-STARRS1 telescope on the summit of Haleakala in Hawaii were among the first to help identify the stellar remains.

Supermassive black holes, weighing millions to billions times more than the sun, lurk in the centers of most galaxies. These hefty monsters lie quietly until an unsuspecting victim, such as a star, wanders close enough to get ripped apart by their powerful gravitational clutches. (more…)

Bird Song Yields a New Understanding of Cooperation

*A bird duet springs forth from each bird’s knowledge of the entire song*

The site of a volcano isn’t the first place one might think of to study cooperation. But neuroscientist Eric Fortune of Johns Hopkins University and colleagues went to the slopes of Antisana volcano in Ecuador to study cooperation as it plays out with a very special songbird, the plain-tailed wren. Funded in part by the National Science Foundation, the researchers report their observations in the Nov. 4, 2011, issue of Science.

Rapidly alternating their singing back and forth, female and male wrens cooperate to sing a duet that sounds as if a single bird sang it. The researchers assumed that the brain of each bird would have a memory of its own part of the duet, and also have a memory of the cues from its partner. They were surprised to find that both brains had a record of the complete duet–a performance that neither bird can do by itself. (more…)
