ANN ARBOR — A glass plate with a nanoscale roughness could be a simple way for scientists to capture and study the circulating tumor cells that carry cancer around the body through the bloodstream. (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…)

SAN FRANCISCO — Satellite observations have revealed the first direct evidence of smoke from Arctic wildfires drifting over the Greenland ice sheet, tarnishing the ice with soot and making it more likely to melt under the sun. (more…)
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…)
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…)
Friends may help reduce package delivery costs

Groundbreaking research by a team of UCLA physicians and engineers demonstrates that prostate cancer — long identifiable only through painful, hit-or-miss biopsies — can be diagnosed far more easily and accurately using a new image-guided, targeted biopsy procedure. (more…)
