A new and virulent strain of adenovirus, which frequently causes the common cold, has spread in parts of the United States, killing 10 people and putting dozens into hospitals, U.S. health officials said on Thursday.
A U.S. Centers for Disease Control and Prevention report detailed cases of people ill since May 2006 with a strain of the virus called adenovirus 14 in New York, Oregon, Washington state and Texas.

Concerned with toxic chemicals, more people are buying products with labels like "organic," "green," and "natural." But a consumerist response to environmental threats is not only inadequate, it is dangerous.
Organic food has boomed in the last decade, moving from a tiny niche market to a $17 billion dollar industry. Those who can afford it are buying nontoxic and organic rugs, mattresses, and clothing. Almost half of all households in the US have purchased a water filter of one kind or another. Across the country, people are growing more concerned with the possibility that their food and water could actually make them sick -- and are responding by buying more products with labels like "organic," "green," and "natural."

The congressional budget office (CBO) releases its updated long-term projections for Medicare and Medicaid this week. They will almost certainly show a frightening story.
Healthcare costs in the United States are expected to hugely outpace the growth in income and inflation. When these increases are projected out over 50 or 100 years, the picture is very frightening indeed. In fact, many prominent politicians and political pundits have made a career out of scaring the public with these projections, warning of long-term budget deficits in excess of $70tn (approximately 7% of future GDP). Of course the scare stories usually neglect to point out that the vast majority of the projected deficit is due to our broken healthcare system.
If grandma gets a bedsore, the best thing to put on it might be a plant that's been used for 5,000 years.
The mysterious Aloe vera has been a source for healing since Old Testament times, and a Texas A&M University researcher is trying to uncover just what the substances are in the plant that work wonders and how they do it so that more might be learned about treating wounds.
Dr. Ian Tizard, a professor of immunology in the College of Veterinary Medicine, is studying a special polysaccharide, the substance that forms along cell walls of the Aloe vera, to see how it performs its healing tricks.
The Aloe vera is native to North Africa but now can be found almost worldwide, Tizard says. A succulent, it thrives in warm and dry climates very much like cactus does.
But unlike its prickly cactus cousin, Aloe vera is in a class by itself when it comes to certain healing properties.
There are more than 100 species of aloe, but Tizard says Aloe vera is the one that has drawn the most scientific interest.
There is little substantive evidence that binge drinking while pregnant seriously harms the developing fetus, finds a study in the Journal of Epidemiology and Community Health.
Consistently heavy drinking throughout pregnancy has been associated with birth defects and subsequent neurological problems. But it is not known what impact binge drinking, in the absence of regular heavy drinking, might have. And this drinking pattern is becoming increasingly common, particularly among women, say the authors.
Their findings are based on a comprehensive review of published research on binge drinking and women who were either pregnant or trying to conceive.
The next time you find yourself wondering, "Teenagers! Why do they do that?", look to their adolescent brains. New research suggests that the risk-taking behaviors seen in adolescents may be attributed to their still developing brains. Another study explores the brain basis for the risk-taking behaviors of psychopaths.
The new research was presented at the 34th Society for Neuroscience annual meeting in San Diego.
New research--in both humans and animals--shows differences in the structure and functioning of adolescent brains compared with preadolescents or adults that correspond to such teenage behaviors as immature decision making, increased risk taking, and impulsive behaviors. As a result of this research, scientists now urge that puberty be studied as a separate stage of development--one distinctly different from the life stages of children or adults.
The rates of three leading sexually transmitted diseases -- chlamydia, gonorrhea and syphilis -- rose again in the United States last year, worried public health officials said on Tuesday.
It was the second year in a row of increases for all three of these sexually transmitted bacterial infections, the Centers for Disease Control and Prevention said.
The rate of chlamydia, the most common infectious disease reported to the CDC, increased 5.6 percent in 2006 from 2005.
Forty-one neurons is a drop in the ocean compared with the hundred billion or so cells that are present in our brains. But those few neurons could help Eric Ramsey talk again.
It is eight years since a car accident left Ramsey "locked-in" - aware but paralysed and unable to communicate other than through eye movements. By listening in on a tiny population of cells in his brain, neuroscientists hope to give him back his "voice" - a first for someone with his problems.

A startling new study by medical researchers in the United States has caused consternation among public health professionals by suggesting that, contrary to conventional wisdom, being overweight might actually be beneficial for health.
The study, published yesterday in the respected Journal of the American Medical Association, runs counter to almost all other advice to consumers by saying that carrying a little extra flab -- though not too much -- might help people to live longer.

Some viruses being used in experimental AIDS vaccines may damage the immune system by exhausting key cells, researchers reported on Thursday in a finding that may further cloud the field of HIV vaccines.
