Study recommends a nip of chocolate
The dark confection lowers blood pressure in a small study that echoes other research on cocoa. The dark side: It takes only a tiny amount to have that effect.

Chicago - Here's some good and bad news for chocoholics: Dark chocolate seems to lower blood pressure, but it requires an amount less than two Hershey's Kisses to do it, a small study suggests. The new research from Germany adds to mounting evidence linking dark chocolate with health benefits, but it's the first to suggest that just a tiny amount may suffice.

Alzheimer's study on the nose?
Fading sense of smell may be disease omen
By Carla K. Johnson The Associated Press
Article Last Updated: 07/03/2007 02:51:08 AM MDT
Chicago - Difficulty identifying common smells such as lemon, banana and cinnamon may be the first sign of Alzheimer's disease, according to a study that could lead to scratch-and-sniff tests to determine a person's risk for the progressive brain disorder. Such tests could be important if scientists find ways to slow or stop Alzheimer's and the severe memory loss associated with it. For now, there's no cure for the more than 5 million Americans with the disease.

Stress can lead to obesity, study says

Article Last Updated: 07/02/2007 12:24:15 AM MDT
Scientists say they have found a link between stress and obesity, which offers hope in treating the one-third of Americans who are overweight. The brain under stress releases a hormone that activates a gene in fat cells, causing them to grow in size and number, according to a study published Sunday in the journal Nature Medicine. Scientists found stressed mice gained twice as much fat as those fed the same high-calorie diet. The stressed mice didn't gain weight when the gene was removed or blocked.

Diaper Data Sheds Light on Intestinal Development
Talk of the Nation, June 29, 2007 · Scientists tracking the surprising things that (literally) come out of a baby over the course of a year have been able to trace a timeline of the development of bacterial ecosystems within the human gut. Scientists are learning more about how our intestinal tracts become colonized with bacteria.

Cultivation in Americas dates back 10,000 years
By Randolph E. Schmid The Associated Press
Article Last Updated: 06/29/2007 01:50:42 AM MDT
Washington - Agriculture was taking root in South America almost as early as the first farmers were breaking ground in the Middle East, new research indicates.
Evidence that squash was being grown nearly 10,000 years ago, in what is now Peru, is reported in today's edition of the journal Science.
A team led by anthropologist Tom D. Dillehay of Vanderbilt University also uncovered remains of peanuts from 7,600 years ago and cotton dated to 5,500 years ago in the floors and hearths of sites in the Nanchoc Valley of northern Peru.
"We believe the development of agriculture by the Nanchoc people served as a catalyst for cultural and social changes that eventually led to intensified agriculture, institutionalized political power and new towns in the Andean highlands and along the coast 4,000 to 5,500 years ago," Dillehay said.

Researchers: Antarctica Ice Sheet Stable
(originally seen in the Denver Post, 6/28/07)
By RAY LILLEY Associated Press Writer
WELLINGTON, New Zealand (AP) -- An ice sheet in Antarctica that is the world's largest - with enough water to raise global sea levels by 200 feet - is relatively stable and poses no immediate threat, according to new research.
While studies of the Greenland and West Antarctic ice sheets show they are both at risk from global warming, the East Antarctic ice sheet will "need quite a bit of warming" to be affected, Andrew Mackintosh, a senior lecturer at Victoria University, said Wednesday.
The air over the East Antarctic ice sheet, an ice mass more than 1,875 miles across and up to 2.5 miles thick centered on the South Pole, will remain cold enough to prevent significant melting in the near future, the New Zealand-led research shows.

Study: Pet care industry is booming
WASHINGTON, June 26 (UPI) -- The American Chemical Society said U.S. pet owners spent $18.5 million last year on veterinary care, medications and other non-food pet supplies.
And as people around the world devote more of their income to keeping pets healthy and comfortable, pharmaceutical companies are devoting more research to pet health.
Writing in the ACS journal Chemical & Engineering News, Associate Editor Rachel Petkewich reported the amount of money spent on pet care in the United States is expected to grow by more than 6 percent annually. And that, she said, is spurring global pharmaceutical companies best known for making human medicines to devote more research dollars for their animal health divisions.

Technology turns glycerin into ethanol
HOUSTON, June 25 (UPI) -- U.S. scientists have developed a technology designed to convert waste glycerin from biodiesel plants into ethanol, another popular biofuel.
Rice University Assistant Professor Ramon Gonzalez and colleagues identified the metabolic processes and conditions that allow a strain of E. coli to convert glycerin into ethanol.
"It's also very efficient," said Gonzalez. "We estimate the operational costs to be about 40 percent less that those of producing ethanol from corn."

Echinacea Halves Chances of Getting Cold, Review Finds
By Frances Schwartzkopff
June 25 (Bloomberg) -- Echinacea, the North American flower widely used to protect against colds, actually works - and works well - a scientific review found.
The plant, also known as the purple cornflower, reduced the chances of getting a cold by nearly two-thirds compared with a placebo, according to the review, which independently analyzed the results of 14 clinical studies. Echinacea also cut a cold's duration by as many as four days, according to the review, published today in The Lancet Infectious Diseases.
``Echinacea is one of the most commonly used herbal products, but controversy exists about its benefit in the prevention and treatment of the common cold,'' lead author Sachin A. Shah, of the University of Connecticut School of Pharmacy, wrote. The review found ``echinacea decreased the odds of developing the common cold by 58 percent.''

Psychotherapy can prove harmful to certain patients: Report
New York, June 11: Psychotherapy -- the treatment method used to cure emotional disorders by counselling and communicating with patients -- could be dangerous for some, a media report said today. "The profession hasn't shown much interest in the problem of treatments that can be harmful. Of the few psychotherapies that have been for safety, too many cause harm to at least some patients," Newsweek quoted psychology professor Scott Lilienfeld of Emory University as saying. Few patients seeking psychotherapy know that talking can be dangerous and the therapies are not "exactly rushing to tell them so," it said.
