Recording studio that spans a continent
On Saturday September 23, a jazz group will perform in a concert hall at McGill University in Montreal and the recording engineers mixing the 12 channels of audio during the performance will not be in a booth at the back of the hall, but rather in a theatre at the University of Southern California in Los Angeles.

Vaccines designed to trigger an immune response to a small HIV protein called Tat could be a promising way to fend off the virus, intriguing new data suggest.

American Thoracic Society journal news tips for September
News from the American Thoracic Society September journals includes research showing that urban living constitutes the biggest risk for asthma in children; tuberculosis (TB) has become the most common opportunistic infection in human immuno- deficiency virus (HIV); and that prenatal steroids directly increase the production process of surfactant in very premature infants with respiratory distress syndrome (RDS).

Sidebar: new trial should lead to better understanding of why exercise is an effective treatment for depression
The Duke University Medical Center researchers who found evidence that exercise can be an effective treatment for major depression are embarking on a larger trial they believe will answer some of the remaining questions posed by their earlier results.

Scientists link energy metabolism and fertility
HHMI researchers have discovered that a protein that translates insulin signals during carbohydrate metabolism also plays an important role in female reproduction, regulation of appetite and obesity in mice.

Spooky photons make break miniaturization barrier for computers
In the 25 September issue of the journal Physical Review Letters, researchers show that a special kind of light, known as 'entangled photons' may someday enable manufacturers to continue miniaturizing computer chips and other electronic devices.

K-State professor develops vaccine to stop liver abscess in cattle
Beef producers might get to say good-bye to the current antibiotics they use to deter liver abscess in cattle, and hello to a vaccine that is easier to use and could cost less.

Artificial muscles release medicine from tiny implants
Scientists have come one step closer to creating 'smart' medical implants with the development of tiny artificial muscles at Ohio State.

Effect of exercise on reducing major depression appears to be long-lasting
After demonstrating that 30 minutes of brisk exercise three times a week is just as effective as drug therapy in relieving the symptoms of major depression in the short term, Duke University Medical Center researchers have now shown that continued exercise greatly reduces the chances of the depression returning.

University of Maryland researchers create a new pathway for sight by 'rewiring' the brain in animal study
By surgically 'rewiring' the brains of newborn hamsters, researchers at the University of Maryland School of Medicine and the University of Montreal have shown that they can create new brain circuits that take over the functions of damaged ones.

Hutchinson Center receives $1.2 million from National Science Foundation to study plant genetics
The Fred Hutchinson Cancer Research Center has received a $1.2 million first-year grant from the National Science Foundation to implement a new strategy for obtaining plants with desirable genetic muations -- without transgenic manipulation.

Scientists fear loss of colobus monkey heralds beginning of 'extinction spasm' of many West African species
The researchers who documented the extinction of the little- studied 'Miss Waldron's red colobus monkey' say it may be the first obvious manifestation of an extinction spasm that will soon affect other large animals in West Africa unless more rigorous protection is applied immediately.

Bees deliver fungicide more effectively than sprays, study finds
Researchers have found that bees can deliver a biological fungicide to strawberry blooms more effectively than can mechanical sprayers.

New therapies combine chip technology, material science and bioengineering
Bioengineers are now using nanotechnology to create biohybrid grafts--implants that contain living and nonliving materials- -and sophisticated drug delivery systems that target therapy to a precise location in the body, protect the device from attack by the body's defenses, and release the drug in response to a signal.

Congressional briefing on how neighborhoods matter

Gene therapy plus radiation therapy shows the way to better cancer treatments
New gene therapy techniques can enhance the action of radiation therapy and significantly improve patients' outcome, say researchers.

Purdue researchers unveil program to track crop traits
Seed companies, grain handlers and food processors will have an easier time tracking value-added, genetic traits in crops thanks to a new computer program developed by Purdue University researchers. he program will help breeders and producers develop crops that are more nutritious, are easier to process or have pharmaceutical properties.

Tiny polymer patterns might act as glue in 'biochips'
Engineers have developed a technique that might be used to glue cells or DNA to the surfaces of computer 'biochips,' a technology aimed at making diagnostic devices to be implanted in the body or used to quickly analyze food and laboratory samples.
