The brain mechanism underlying the mind-bending effects of hallucinogens such as LSD, mescaline, and psilocybin has been discovered by neuroscientists.

We haven't come that far, baby. In the 1970's male cartoon characters outnumbered female cartoon characters by a ratio of almost four to one. Research presented at the American Psychological Association's (APA) 105th Annual Convention in Chicago reveals that male cartoon characters still outnumber female cartoon characters almost four to one. Male characters are also still portrayed as dominate, powerful and aggressive. Female characters don't have any "character" at all.

Despite TV watchdogging, Cynthia Spicher, B.A., and psychologist Mary Hudak, Ph.D., from Allegheny College have found little change in the gender stereotypes that America's young minds are spending two to four hours a day viewing.

To see what progress has been made in portraying gender stereotypes in cartoon characters, Dr. Spicher and Dr. Hudak videotaped and categorized 118 cartoon characters from a single episode of each of the following Saturday morning cartoons: The Bugs Bunny/Tweety Show, Aladdin, Ninja Turtles, The Mask, Eek!stravaganza, Spiderman, Tick and Life with Louie. Characters were rated on sex, prominence, gender stereotyping, aggressive behaviors and occupational roles.

The theorists who first created the mathematics that describe the behavior of the recently announced "invisibility cloak" have revealed a new analysis that may extend the current cloak's powers, enabling it to hide even actively radiating objects like a flashlight or cell phone.

Allan Greenleaf, professor of mathematics at the University of Rochester, working with colleagues around the globe, has announced a mathematical theory that predicts some strange goings on inside the cloak—and that what happens inside is crucial to the cloak's effectiveness.

Pulickel Ajayan, the Henry Burlage Professor of Materials Science and Engineering, is being awarded the MRS Medal from the Materials Research Society and has been named by Scientific American magazine as a Research Leader within the 2006 "Scientific American 50" -- the magazine's prestigious annual list recognizing outstanding acts of leadership in science and technology.

"Professor Ajayan is a world-renowned expert in fabricating materials and devices based on his creative chemical and physical manipulation of carbon," said Acting Provost Robert Palazzo. "His research is unlocking information about how to direct the assembly of carbon at the atomic level, providing opportunities for the assembly of a cornucopia of carbon-based nanostructures.

ESA's Mars Express has obtained images of the Cydonia region, site of the famous 'Face on Mars.' The High Resolution Stereo Camera photos include some of the most spectacular views of the Red Planet ever.

After multiple attempts to image the Cydonia region from April 2004 until July 2006 were frustrated by altitude and atmospheric dust and haze, the High Resolution Stereo Camera (HRSC) on board Mars Express finally obtained, on 22 July, a series of images that show the famous 'face' on Mars in unprecedented detail.

The data were gathered during orbit 3253 over the Cydonia region, with a ground resolution of approximately 13.7 metres per pixel. Cydonia lies at approximately 40.75° North and 350.54° East.
