August 31, 2007 09:59 AM - Wendy Edelstein, UC Berkley

University of California, Berkeley - Researcher Cheri Jo Pascoe spent a year and a half hanging out in a high-school weight room, auto shop, and drama class, and she learned what frightens adolescent males most. “Being called a fag is the specter that constantly lurks” in the minds of high-school boys, explains Pascoe, a postdoctoral scholar at the Institute for Social Change, UC Berkeley.

Experimental anti-cancer drug made from corn lillies kills brain tumor stem cells
August 31, 2007 09:23 AM - Johns Hopkins Medical Institutions

A drug that shuts down a critical cell-signaling pathway in the most common and aggressive type of adult brain cancer successfully kills cancer stem cells thought to fuel tumor growth and help cancers evade drug and radiation therapy, a Johns Hopkins study shows. In a series of laboratory and animal experiments, Johns Hopkins scientists blocked the signaling system, known as Hedgehog, with an experimental compound called cyclopamine to explore the blockade’s effect on cancer stem cells that populate glioblastoma multiforme. Cyclopamine has long been known to inhibit Hedgehog signaling.

New technique detects specific chromosomal damage, may indicate lung cancer risk
August 31, 2007 08:26 AM - American Thoracic Society

A new technique could pave the way toward screening people at risk for lung cancer for the genetic changes that may foreshadow malignancies, researchers from the University of Colorado say. “The most successful way to reduce mortality in cancer is prevention,” said researcher Wilbur A. Franklin, M.D., Professor of Pathology at the University of Colorado Health Sciences Center. “Our goal would be to develop screening techniques for lung lesions that could enable us to identify precancerous changes.”

Fad Autism Treatments Grow On Internet
August 30, 2007 06:03 PM - Ohio State University

SAN FRANCISCO — Ineffective or even dangerous fad treatments for autism, always a problem, seem to be growing more pervasive, according to researchers who studied the problem. “Developmental disabilities like autism are a magnet for all kinds of unsupported or disproved therapies, and it has gotten worse as more children have been diagnosed with autism,” said James Mulick, professor of pediatrics and psychology at Ohio State University .”

Chinese officials on Wednesday pledged to crack down on the sale of illegal performance-enhancing drugs on the Internet. China was tainted with a string of doping scandals in sport in the 1990s, but since then it began to step up efforts to fight against drugs. The number of dope tests totaled 9,424 last year and is expected to be more than 10,000 this year, according to Jiang.

ANN ARBOR, Mich.— A camper who chases a grizzly but won't risk unprotected sex. A sky diver afraid to stand up to the boss. New research shows that not all risk is created equal and people show a mixture of both risky and non-risky behaviors. The survey also shows that men are significantly riskier than women overall.

Study: Cirrhotic Alcoholics Get More Brain Damage
August 30, 2007 01:57 PM - University of Texas at Austin

AUSTIN, Texas—An examination of gene expression in the frontal cortex has found that brain function is even more impaired in alcoholics with cirrhosis of the liver, one of the most common and serious medical complications linked to alcoholism. Sustained exposure to alcohol can cause scarring and dysfunction of the liver, referred to as cirrhosis. Heavy alcohol use can also cause brain damage.
