Population shifts, not storms, have caused rise in property losses
Don't blame staggering property losses of the 1990s solely on changing weather or global warming. A review of 50 years of insurance and weather records puts the blame on the movement of an ever-growing U.S. population to the coasts and major urban areas.
Stigma of mental illness still exists
Although the American public does not view all people with mental illness uniformly, evidence of stigma toward the mentally ill remains, results of a new national survey reveal.
Mayo Clinic study reports that centenarians do well following surgery
It's not how old you are; it's how sick you are -- at least when it comes to recovery following surgery. This is the major finding of a Mayo Clinic study of 31 men and women 100 years old or older.
Scientists image key steps in bacterial infection
For the first time, scientists have obtained 3-D snapshots of crucial steps in bacterial infection. One set of X-ray images should aid in the fight against bladder infection. A second set captures a key event in kidney infection.
Drought worsens, spreads
The USGS reports that this summer's drought, already the century's third worst in the Mid-Atlantic, continues to worsen and is spreading into northeastern states, the Carolinas and west into Ohio and Indiana. Meanwhile, in the Mid-Atlantic, drinking water supplies are being threatened in some areas as salty ocean water moves upstream into normally freshwater areas
Whole-organ pancreas transplants and partial liver transplant programs arepriorities for renowned transplant surgeon at Cedars-Sinai
A functioning whole-organ pancreas transplant is the only therapy available that can reliably remove the need for insulin injections in a Type I diabetic.

Factor for acquiring skin barrier function identified
Researchers at the University of Chicago have discovered a critical factor necessary for the skin to acquire its barrier function--the ability to keep water in and microbes out. Their findings, based on knockout mouse studies, provide researchers with an animal model on which to test novel therapies for premature babies whose skin has not acquired barrier function.
Psychological attributes, not physical gifts, of young athletes predict success, say coaches in a new study
In a new study examining how much psychological and physical characteristics matter in the development of young athletes, psychologist Shari Kuchenbecker, Ph.D., found that psychological factors were most important in achieving athletic success. And too much pressure and criticism were the most harmful to a young athlete's development. These findings will be presented at the 107th Annual Convention of the American Psychological Association in Boston.

Published in Nature Medicine, the finding is a dramatic new approach focusing on fat storage rather than on controlling appetite.
Even in the Amazon jungles, treatment for heat exhaustion is the same as it is right here at home
Whether you plan to trek through the Peruvian Amazon or ride a bike on a sunny day in Los Angeles, Dr. Hardy, director of the Integrative Medicine Medical Group at Cedars-Sinai Medical Center, says preparing yourself ahead of time for the heat is the most important preventive measure you can take.
USGS 'put me on hold' so popular that new number is installed -- or buy it on a CD
The information that callers hear when they get put on hold after calling the U.S. Geological Survey, is so interesting that some of them are calling back and asking to be put on hold. Now they can do just that by calling 650-329-2288.
12-year-old Oregon girl is first child to receive new bone growth material in her skull
Physicians at Oregon Health Sciences University's Doernbecher Children's Hospital have applied bone morphogenic protein to huge holes in 12-yr-old Emily Lang's skull. BMP ignities a molecular and cellular process prompting the body to grow new bone structures. Emily first had BMP applied to a small hole in her skull last year. Since then 70 percent of that gap is now filled with bone. On Aug. 23 she received another dose, this time across her entire forehead.
Cigarette brand switchers more likely to quit smoking
Smokers who switch to lower tar or nicotine cigarettes for 'health reasons' are more likely to subsequently quit smoking compared with those who continue to smoke regular cigarette brands, according to researchers at the University of Memphis, University of Missouri-Kansas City, University of Minnesota and the U.S. Air Force.
Immune molecule found to kill indirectly by closing receptor to live-saving help
Instead of killing damaged cells directly as once believed, an immune molecule works behind the scenes, shutting down receptors within neurons that normally welcome a separate life-saving protein with open arms, a team of scientists say. The discovery sheds new insight on the cross-talk of two proteins within damaged cells, suggesting a new way to approach the treatment of neurodegenerative diseases.
Study finds parental influence still important during adolescence
New research suggests that parents continue to influence their adolescents' behavior, even as friends and schools loom larger in teens' eyes. A study at Ohio State University used a national data set to track 1,725 children for five years, beginning when they were between 11 and 17 years old.
Risk factors for stroke after heart surgery identified
A new study helps identify which individuals may have the highest risk of stroke following heart surgery. Reporting in today's Circulation: Journal of the American Heart Association, researchers found that heart surgery patients who had previously had a stroke faced the highest risk. They had a 14-times higher risk of having a new stroke during or after surgery.
Rescuing brain cells in stroke patients from the brink of suicide
For several days after a patient suffers a stroke, brain cells are bombarded with molecular 'pro-death' signals carrying such bad news about the brain environment that cells are tempted to commit suicide. University of Rochester scientists have enlisted an unlikely ally, the herpes virus, to help brain cells choose life.
Drug companies responded poorly to requests for information from doctors in Pakistan
Many doctors in the developing world do not receive adequate or appropriate responses when they request product information from drug companies, claim doctors from Pakistan in this week's BMJ.

Cinnamon is lethal weapon against E. coli O157:H7
When cinnamon is in, Escherichia coli O157:H7 is out. That's what researchers at Kansas State University discovered in laboratory tests with cinnamon and apple juice heavily tainted with the bacteria. Presented at the Institute of Food Technologists' 1999 Annual Meeting in Chicago on July 27, the study findings revealed that cinnamon is a lethal weapon against E. coli O157:H7 and may be able to help control it in unpasteurized juices.
Meditation decreases blood pressure
Transcendental Meditation decreases blood pressure by reducing constriction of the blood vessels and thereby decreases the risk of heart disease, new research shows. Scientists at the Medical College of Georgia examined how Transcendental Meditation decreases constriction of blood vessels and effects the heart's output.
New coating could lead to safer, more convenient asthma drugs
People who suffer from asthma won't have to breathe into inhalers repeatedly throughout the day -- or worry about harmful side effects of asthma drugs -- if a new coating proves as successful in humans as it has in rats. The coating covers tiny drug particles contained in many asthma inhalers with a polymer 1,000 times thinner than a human hair.
Chemists' pay rises at three times the rate of the Consumer Price Index

Help with 'screamingly radioactive' storage tanks: Nonradioactive substitute created to aid nuclear waste clean-up
Synthetic goods are generally modeled on scarce but desirable materials -- diamonds, fine wools, even fruit juices. Jim Krumhansl's offering to the world is a bit different. Krumhansl has created synthetic sludge.Unappetizing, perhaps? You thought there was enough of the real thing? But the unusual product, which harmlessly mimics the deadly sludge found in underground nuclear waste storage tanks, could save U.S. taxpayers hundreds of millions of dollars in cleanup costs.
