EAST LANSING, Mich. — Peer influence and low self-control appear to be the major factors fueling juvenile cybercrime such as computer hacking and online bullying, according to a new study led by a Michigan State University criminologist.

Thomas Holt, assistant professor of criminal justice, said the findings reinforce the need for parents to be more aware of their children’s friends and Internet activities.

“It’s important to know what your kids are doing when they’re online and who they are associating with both online and offline,” Holt said. (more…)

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…)
