Tiny hairs on bats’ wings act as speedometers

COLLEGE PARK, Md.- Anyone watching bats skillfully maneuvering through the air to catch their dinner is impressed by how they quickly change direction and speed. Now researchers in the A. James Clark School of Engineering at the University of Maryland believe they have uncovered one of the secrets of bats’ aerodynamic prowess: rows of microscopic, domed hairs on their wings that might act like speedometers and stall indicators.

Samples of icy spray shooting from Saturn’s moon Enceladus collected during Cassini spacecraft flybys show the strongest evidence yet for the existence of a large-scale, subterranean saltwater ocean, says a new international study led by the University of Heidelberg and involving the University of Colorado Boulder.

The new discovery was made during the Cassini-Huygens mission to Saturn, a collaboration of NASA, the European Space Agency and the Italian Space Agency. Launched in 1997, the mission spacecraft arrived at the Saturn system in 2004 and has been touring the giant ringed planet and its vast moon system ever since. (more…)

A new advance by UCLA biochemists has brought scientists one step closer to developing treatments that could delay the onset of Alzheimer’s disease and prevent the sexual transmission of HIV.

The researchers report that they have designed molecular inhibitors that target specific proteins associated with Alzheimer’s disease and HIV to prevent them from forming amyloid fibers, the elongated chains of interlocking proteins that play a key role in more than two dozen degenerative and often fatal diseases.

EAST LANSING, Mich. — Women’s bias against male strangers increases when women are fertile, suggesting prejudice may be partly fueled by genetics, according to a study by Michigan State University psychology researchers.

The study, funded by the National Science Foundation, appears online in Psychological Science, a major research journal.

“Our findings suggest that women’s prejudice, at least in part, may be a byproduct of their biology,” said Melissa McDonald, a doctoral student and lead author on the paper. (more…)

SAN FRANCISCO – June 23, 2011 – A collection of students who want to change the world with technology pitched their ideas to Silicon Valley industry experts, academics, and media on Wednesday.

Several teams of students who will participate in the July Imagine Cup 2011 Worldwide Finals in New York City got to first showcase their projects to people who could help them refine their concepts, find markets for their ideas, and eventually find investors to provide the money they will need to turn their ideas turn into viable businesses.
