Leaded Lipsticks a Concern for Young, Frequent Users, Expert Says
October 16, 2007 04:17 PM - Campaign for Safe Cosmetics Newswire
WEST LAFAYETTE, Ind. - A Purdue University expert says a recent study discussing levels of lead in lipstick should empower consumers with information to take more personal responsibility for their health.
The Campaign for Safe Cosmetics said tests on 33 brand-name red lipsticks by a California testing group found that 61 percent had detectable lead levels of 0.03 to 0.65 parts per million.
Wei Zheng, (pronounced Way Zsheng) a professor and university faculty scholar in Purdue's School of Health Sciences, studies the toxic effects of heavy metals on the brain.
"It is interesting to me that cosmetics companies considered these relatively small amounts," Zheng says. "Other recent studies have shown that there really is no such thing as a safe level of lead in the blood."
China launches Effort To Green Inner Mongolian Desert
October 16, 2007 04:00 PM -
Bejing, China - Beijing and Seoul recently signed an agreement to launch a joint program to harness China's eighth-largest desert - the Ulan Buh in North China's Inner Mongolia Autonomous Region.
About 15 million yuan (1.99 million U.S. dollars) will be spent growing trees and building greenhouses to prevent environmental deterioration in the Ulan Buh region, according to officials involved in the project.
Study: Big Tobacco's War On Linking Secondhand Smoke And Heart Disease
October 16, 2007 12:46 PM -
San Francisco, California - After combing through nearly 50 million pages of previously secret, internal tobacco-industry documents, UC Davis and UC San Francisco researchers say they have documented for the first time how the industry funded and used scientific studies to undermine evidence linking secondhand smoke to cardiovascular disease.
In a special report published in the Oct. 16 issue of the journal Circulation, authors Elisa K. Tong and Stanton A. Glantz say that the tobacco-related documents they reviewed show how the industry initially worked to question scientific evidence about the harmful effects of secondhand smoke as a way to fight smoke-free regulations. More recently, they suggest, tobacco-company-funded studies have been conducted to support the development of so-called "reduced-harm" cigarettes.
Most complete new giant dinosaur found in Patagonia
October 16, 2007 08:35 AM - Andrei Khalip -Reuters
Brazilian and Argentine paleontologists have discovered the largely complete fossil of a new species of giant dinosaur that roamed what is now northern Patagonia about 80 million years ago.
The herbivorous Futalognkosaurus dukei measured an estimated 105 feet to 112 feet from head to tail and was as high as a four-storey building. It is one of the three biggest dinosaurs yet found in the world.
Heart deaths, suicides up after weightloss surgery
October 15, 2007 11:15 PM -
NEW YORK (Reuters Health) - Among people who have undergone so-called bariatric surgery for obesity, death rates are higher than seen among other people of the same age, new research shows. In particular, deaths due to suicide and coronary heart disease are higher than might be expected normally.
The study looked at data for all Pennsylvania residents who underwent a bariatric operation such as stomach stapling or gastric bypass between 1995 and 2004. Deaths in these patients were compared with those seen in the general population.
A total of 440 deaths were noted after 16,683 weightloss procedures during the study period, Dr. Lewis H. Kuller, from the University of Pittsburgh, and colleagues report.
Wyeth Jury Awards $99 Million: HRT Drugs Blamed For Cancers
October 15, 2007 11:11 PM -
RENO, Nevada (Reuters) - A Nevada jury on Monday awarded $99 million in punitive damages to three women who blamed their breast cancer on Wyeth hormone replacement drugs.
Judge Robert Perry, presiding over the case in the Washoe County District Court, slashed the compensatory damages to $35 million from $134.5 million on Friday, after the jury said the original sum included some punitive damages.
The new total is about the same as the original figure.
Cancer death rates continue to fall

WASHINGTON (Reuters) - Death rates from cancer continue to fall in the United States, dropping more than 2 percent per year from 2002 through 2004, cancer experts reported on Monday.
They found important declines in deaths from lung, prostate and colorectal cancers in men, as well as in breast and colon cancer among women. Lung cancer deaths were still on the rise among women but this increase slowed, according to the report.
"The significant decline in cancer death rates demonstrates important progress in the fight against cancer that has been achieved through effective tobacco control, screening, early detection, and appropriate treatment," U.S. Centers for Disease Control and Prevention Director Dr. Julie Gerberding said in a statement.
Air Pollution Linked To Bronchitis In Preschoolers
October 15, 2007 10:04 AM -
Davis, California - In one of the first studies to examine air pollution in relation to infant and early childhood health, a UC Davis researcher has discovered a strong link between exposure to components of air pollution and acute bronchitis diagnoses in preschool-aged children. Those components - polycyclic aromatic hydrocarbons, or PAHs - contribute to air pollution from a variety of sources, including coal burning, vehicle exhaust, wood-burning stoves, tobacco smoke and grilling food.
Led by UC Davis environmental epidemiologist Irva Hertz-Picciotto, the Czech Early Childhood Health Study involved 1,133 children from birth to 4.5 years of age born in two districts of the Czech Republic between 1994 and 1998. One of those districts, Teplice (pronounced Tuh-PLEET-zuh), is known for its high levels of air pollution. The other, Prachatice (pronounced prah-kuh-TEET-zuh), has much lower levels of air pollution.

No sex for 40 million years? Works for some
October 14, 2007 10:45 PM - Michael Kahn, Reuters
LONDON (Reuters) - One microscopic organism has thrived despite remaining celibate for tens of millions of years thanks to a neat evolutionary trick, researchers said.
Asexual reproduction has allowed duplicate gene copies of the single-celled creatures -- called bdelloid rotifers -- to become different over time.
This gives the rotifers a wider pool of genes to help them adapt and survive, the researchers said in the journal Science.
"It is like having a bigger tool kit," Alan Tunnacliffe, a molecular biologist at the University of Cambridge, said in a telephone interview. "You can do the same job but better."
