Researchers at Michigan State University have discovered a protein that does its best work with one foot in the grave.

The study, which appears in the current issue of the Journal of Biological Chemistry, focuses on the nontraditional lifestyle of Retinoblastoma tumor suppressor proteins, which could lead to new ways to treat cancer.

“Retinoblastoma proteins are unique in that they use controlled destruction to do their jobs in a timely but restrained fashion,” said Liang Zhang, a lead author and MSU cell and molecular biology graduate student. “This is an unusual way for proteins to act.” (more…)

When we’re faced with things that seem threatening, whether it’s a hairy spider or an angry mob, our goal is usually to get as far away as we can. Now, new research suggests that our visual perception may actually be biased in ways that help motivate us to get out of harm’s way. (more…)

The holidays thrust many people, often happily, into social contexts that encourage overeating. While people often survive the holidays with, on average, only a small weight gain, overeating in December is just as unhealthy as it is at less festive times of year when holiday “license to eat” isn’t in effect. To help guide people healthfully through holiday parties, family dinners, and snacking during downtime at home, Mary Flynn, a clinical associate professor of medicine in the Warren Alpert Medical School and a research dietitian at The Miriam Hospital, offers these tips.

PASADENA, Calif. – Scientists with NASA’s Cassini mission have spotted what appears to be a miniature, extraterrestrial likeness of Earth’s Nile River: a river valley on Saturn’s moon Titan that stretches more than 200 miles (400 kilometers) from its “headwaters” to a large sea. It is the first time images have revealed a river system this vast and in such high resolution anywhere other than Earth. (more…)

Do We Live in a Computer Simulation? UW Researchers Say Idea Can be Tested

A decade ago, a British philosopher put forth the notion that the universe we live in might in fact be a computer simulation run by our descendants. While that seems far-fetched, perhaps even incomprehensible, a team of physicists at the University of Washington has come up with a potential test to see if the idea holds water. (more…)
