PITTSBURGH, Dec. 30 — Closing schools for less than two weeks during a flu pandemic may increase infection rates and prolong an epidemic, say University of Pittsburgh researchers in a study published ahead-of-print and online in the Journal of Public Health Management and Practice. The findings, developed from a series of computer simulations based on U.S.
Jerusalem, December 30, 2009 — Coordination of conservation efforts across national boundaries could achieve significantly higher results and at less cost than conservation actions planned within individual states, researchers at the Hebrew University of Jerusalem and in Australia have found.

Dr. Chu is a physicist. He won a Nobel prize due to his contribution to capture atoms. Now he serves in B. Obama’s government.
CORVALLIS, Ore. — A new study has found that chlorophyll and its derivative chlorophyllin are effective in limiting the absorption of aflatoxin in humans. Aflatoxin is produced by a fungus that is a contaminant of grains including corn, peanuts and soybeans; it is known to cause liver cancer — and can work in concert with other health concerns, such as hepatitis.
An international team of scientists led by researchers at The Scripps Research Institute has developed a straightforward technique to determine the ethnic origin of stem cells.
Pre-market approval by the FDA of cardiovascular devices is often based on studies that lack adequate strength or may have been prone to bias, according to a study in the December 23/30 issue of JAMA.
To assist physicians in caring for a patient demographic that is rapidly growing in size, JAMA is launching a new series, “Care of the Aging Patient: From Evidence to Action.”
It’s going to take infrared eyes to see farther back in time than even the Hubble Space Telescope, and that’s what the James Webb Space Telescope’s MIRI or Mid-Infrared Instrument detectors will do. Now there’s a new short movie that shows what the MIRI detectors are all about and what they can do.
WASHINGTON, D.C. — A gap exists between policy makers’ expectations that current commercial electronic medical records (EMRs) can improve coordination of patient care and clinicians’ real-world experiences with EMRs, according to a study by the Center for Studying Health System Change (HSC) published online in The Journal of General Internal Medicine.
BUFFALO, N.Y. — The role of pharmacists hasn’t received much attention in the debate on the cost of health care.
There is increased evidence that the Arctic could face seasonally ice-free conditions and much warmer temperatures in the future.
Over the past decade, researchers have developed a variety of reliable real-time and archival instruments to study sounds made or heard by marine mammals and fish. These new sensors are now being used in research, management and conservation projects around the world with some very important practical results.
We see the popular “captcha” security mechanism often ? wavy letters websites ask us to type into a box. It’s used by web pages and newsletter sign-up forms to prevent computer robots from hacking into servers and databases. But these codes, which are becoming increasingly complicated for an average person to use, are not immune to security holes.
Lupus may involve inflammation of the kidney, called lupus nephritis, which can impair the kidney’s ability to remove waste from the body. Since normal kidney function is vital, lupus nephritis requires aggressive treatments. Currently, the best way to diagnose kidney inflammation is with a biopsy, which is an invasive procedure that can sometimes have serious side effects.
DETROIT — Not only is acupuncture as effective as drug therapy at reducing hot flashes in breast cancer patients, it has the added benefit of potentially increasing a woman’s sex drive and improving her sense of well-being, according to a Henry Ford Hospital study.
Washington, DC — It’s the ultimate goal in the treatment of cancer: tailoring a person’s therapy based on his or her genetic makeup. While a lofty goal, scientists are steadily moving forward, rapidly exploiting new technologies.
By combining a research technique that dates back 136 years with modern molecular genetics, a Johns Hopkins neuroscientist has been able to see how a mammal’s brain shrewdly revisits and reuses the same molecular cues to control the complex design of its circuits.
ANN ARBOR, Mich.—Just like teenagers at a prom, proteins are tended by chaperones whose job it is to prevent unwanted interactions among immature clients. And at the molecular level, just as at the high school gym level, it’s a job that usually requires a lot of energy.
