Brain Rhythm Associated With Learning Also linked to Running Speed, UCLA Study Shows

Rhythms in the brain that are associated with learning become stronger as the body moves faster, UCLA neurophysicists report in a new study.

The research team, led by professor Mayank Mehta, used specialized microelectrodes to monitor an electrical signal known as the gamma rhythm in the brains of mice. This signal is typically produced in a brain region called the hippocampus, which is critical for learning and memory, during periods of concentration and learning. (more…)

Youth Cybercrime Linked to Friends’ Influence

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…)

University of Maryland Bat Research Promises New Aircraft Speed Detectors

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.

Alina Kabaeva Rules Russia’s Politics

No matter what evil tongues may say, a fact remains a fact. Alina Kabaeva bid farewell to her ribbons, hula-hoops and Indian clubs to conquer politics. Her achievements in politics continue to grow at an impressive pace. For example, Kabaeva, formerly one of world’s most prominent rhythmical gymnasts, has recently been listed as one of world’s sexiest women in politics.

The idea to make the list of most attractive women in politics belongs to US-based journalist Eric Golub. The journalist made a curious list indeed. He did not rate the members of his list from the point of view of their physical attraction. Mr. Golub divided them into three groups: centrist, leftist and rightist female politicians. As a result, 30 women from different countries of the world found themselves in Mr. Golub’s melting pot. (more…)

Strongest Evidence yet indicates Icy Saturn Moon hiding Saltwater Ocean

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…)

Stiff Sediments Made 2004 Sumatra Earthquake Deadliest in History

AUSTIN, Texas — An international team of geoscientists has discovered an unusual geological formation that helps explain how an undersea earthquake off the coast of Sumatra in December 2004 spawned the deadliest tsunami in recorded history. (more…)

Breaking the Chain: ‘Molecular cap’ Blocks Processes that Lead to Alzheimer’s, HIV

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.
