New Biochip Could Replace Animal Testing
December 18, 2007 06:22 PM -
BERKELEY -- With the cosmetics industry facing a European ban on animal testing in 2009, a newly developed biochip could provide the rapid analysis needed to insure that the chemicals in cosmetics are nontoxic to humans.
Many kids may not outgrow cow's milk allergy

NEW YORK (Reuters Health) - Cow's milk allergy persists longer than previously reported, and the majority of children may retain the sensitivity into school age, study findings suggest. "The old data saying that most milk allergy will be easily outgrown, usually by the age of 3 years, is most likely wrong," Dr. Robert A. Wood, at Johns Hopkins University School of Medicine, told Reuters Health. He and colleagues found that just 19 percent of children allergic to cow's milk outgrew their allergy by age 4.
Got fleas? Get the vacuum
December 18, 2007 04:25 PM - Reuters
WASHINGTON (Reuters) - Vacuum cleaners kill fleas just as well as any poison, surprised researchers said on Tuesday. They said a standard vacuum cleaner abuses the fleas so much it kills 96 percent of adult fleas and 100 percent of younger fleas. So no need to worry that a vacuum cleaner bag may turn into a fleabag breeding ground for the pesky, biting creatures, said Glen Needham, associate professor of entomology at Ohio State University. Needham studied the cat flea, or Ctenocephalides felis, the most common type of flea found in households.
Overexcited Neurons Bad for Cell Health
December 18, 2007 04:24 PM -
EVANSTON, Ill. --- Neurotransmitters have consequences. They initiate events that are critical to a healthy life, giving us the ability to move, to talk, to breathe, to think. But that's if the neurotransmitters are getting it right and sending proper signals downstream to muscle cells, neurons or other cells.
FDA to add HIV warning to contraceptive products
December 18, 2007 04:04 PM - Reuters
WASHINGTON (Reuters) - U.S. regulators on Tuesday finalized a rule requiring makers of certain contraceptive gels, foams, films and inserts to carry a warning that the products do not protect against sexually transmitted diseases, including AIDS. The U.S. Food and Drug Administration will require the warning on over-the-counter products containing nonoxynol 9, used in many stand-alone spermicides.
Some Ants Change Their Diet To Survive, Thrive
December 18, 2007 02:00 PM - UC San Diego Newswire
San Diego, California - The ability of Argentine ants to change from carnivorous insect eaters to plant sap-loving creatures has helped these invasive social insects rapidly spread throughout coastal California, according to a new study, displacing many native insects and creating ant infestations familiar to most coastal residents.
Explosives at the microscopic scale produce shocking results
December 18, 2007 01:48 PM - Lawrence Livermore Labs, Newswire
LIVERMORE, Calif. -- U.S. troops blew up enemy bridges with explosives in World War II to slow the advance of supplies or enemy forces. In modern times, ski patrollers use explosives at ski resorts to purposely create avalanches so the runs are safer when skiers arrive. Other than creating the desired effect (a destroyed bridge or avalanche), the users didn’t exactly know the microscopic details and extreme states of matter found within a detonating high explosive. In fact, most scientists don’t know what happens either.
A Unique Way To Lower Energy Costs
December 18, 2007 01:32 PM - UC San Diego, California Newswire
San Diego, California - UC San Diego undergraduate students have designed, built and deployed a network of five weather-monitoring stations as a key step toward helping the university use ocean breezes to cool buildings, identify the sunniest rooftops to expand its solar-electric system, and use water more efficiently in irrigation and in other ways. The network, which will be expanded to 20 stations in 2008, is unprecedented in the United States for the density of weather data to be collected.

Software grant could speed medicinal regeneration technologies
December 18, 2007 11:54 AM -
BLOOMINGTON, Ind. - Regenerative medicine -- as in re-growing human limbs -- sounds like the basis for a Hollywood action movie. But a research group at Indiana University Bloomington led by biophysicist James Glazier will soon provide the scientific community with a new tool to help bring futuristic medical technologies to real-world laboratories. "The future of medicine is in regeneration," said Glazier, who heads Indiana University's Biocomplexity Institute. "And I expect it to be a reality within the next decade."
