The chemical industry has helped fortify our homes against microbial invasion. But is our fear of germs making us even sicker?
The "vomiting virus" now sweeping across Britain may be headed our way. At the same time, San Francisco is being hit with a new strain of the nasty bacterium known as MRSA (methicillin resistant Staphylococcus aureus) -- this one responsible for "flesh-eating pneumonia."
Meanwhile, four patients were recently isolated in the University of Maryland Medical Center, infected with a multidrug resistant bacterium called Acinetobacter baumannii, which has attacked a number of Afghanistan war veterans. As one doctor said of the that bug, "When these people get infected ... you sort of say this is the last straw."
Those new menaces, and more, are joining the usual biological villains that lurk everywhere in midwinter.
Even more than in past years, we're turning to the chemical industry for help in fortifying the American home against microbial invasion. Few go as far as Jacques Niemand, a reclusive Briton who was killed last May by fumes rising from vast quantities of disinfectant that he kept in open buckets around his house to ward off infection. But lower-intensity chemical warfare on our invisible housemates is in full swing.

A mysterious fever has been spreading in the Erathna area in Kuruwita for few days, medical sources said.
According to the sources at Erathna hospital, large number of patients has been admitted to the hospital with similar symptoms of high fever, headache and joint pains.

A new variety of onion developed by scientists in New Zealand will make every chef forget about tears, and chopping onions is set to become a delight, local media said on Friday.
"What we have here is onions, which when you cut them they won't make you cry," Colin Eady, a senior scientist, was cited by TVNZ as saying.

New research from Vanderbilt University shows for the first time that the brain processes aggression as a reward - much like sex, food and drugs - offering insights into our propensity to fight and our fascination with violent sports like boxing and football.
University of Adelaide geneticist Dr Jozef Gecz and a team of Belgium and UK scientists have achieved a major breakthrough in discovering the causes of intellectual disability.
Dr Gecz, a senior researcher who is based at the Women's and Children's Hospital in Adelaide, has collaborated with an international research team to reveal that various mutations of a small part of the X chromosome lead to mental retardation.

In the first study to use imaging technology to see what goes on in the brain when we scratch, researchers at Wake Forest University Baptist Medical Center have uncovered new clues about why scratching may be so relieving - and why it can be hard to stop. The work is reported online in the Journal of Investigative Dermatology and will appear in a future print issue.
"Our study shows for the first time how scratching may relieve itch," said lead author Gil Yosipovitch, M.D., a dermatologist who specializes in itch. "It's important to understand the mechanism of relief so we can develop more effective treatments. For some people, itch is a chronic condition that affects overall health."
The study involved 13 healthy participants who underwent testing with functional magnetic resonance imaging (MRI) technology that highlights areas of the brain activated during an activity. Participants were scratched on the lower leg with a small brush. The scratching went on for 30 seconds and was then stopped for 30 seconds - for a total of about five minutes.

One way diabetes is bad for your blood vessels is by creating too much competition for an amino acid that helps blood vessels relax, researchers say.
That amino acid, L-arginine, is broken down by the enzyme arginase to urea, which helps the body eliminate toxins resulting from the proteins we eat. Diabetics have a lot of arginase activity, which means they use a lot more L-arginine, says Dr. Maritza Romero, postdoctoral fellow at the Medical College of Georgia and lead author of the paper published in the current issue of Circulation Research.
It also means too little L-arginine is available to help nitric oxide synthase make nitric oxide, the powerful vasodilator that helps blood vessels relax, says Dr. Romero, who works in the lab of Dr. R. William Caldwell, chair of the MCG Department of Pharmacology and Toxicology and the study's corresponding author.
