Researchers identify protein important for beginning gene-activation process
Researchers at Penn State have identified the single protein that initiates the gene-activation process.

High homocysteine levels are strongly associated with all-cause mortality among elderly
A high serum level of total homocysteine (tHcy) is generally accepted as a predictor of cardiovascular disease (CVD) risk.

Virus found to carry antibiotic against E. coli
Part of a small virus that attacks only bacteria acts like an antibiotic to destroy E. coli, researchers with the Texas Agricultural Experiment Station have found.

Walnut consumption may reduce heart disease risk by beneficially redistributing cholesterol
Although consumption of as little as 5 ounces of nuts per week has been shown to reduce cardiovascular (CVD) risk by 30-50%, most studies have not differentiated the effects of specific types of nuts.

Intensive therapy improves low back pain, but is it worth the cost?
Intensive rehabilitation programmes reduce pain and improve function in patients with chronic low back pain, concludes a study in this week's BMJ, but it remains unclear whether the improvements are worth the cost of these intensive treatments.

Plant/pathogen evolutionary dynamic defies simple arms race model
The battle between plants and disease-causing pathogens has been compared to an arms race--with each new defense calling forth a new offensive weapon, and neither gaining the upper hand for long.

Research reveals potential of single molecules to function as electronic switches
Your future computer may have components that function based on the action of single molecules.

Women with cystic fibrosis "too embarrassed" to seek help for incontinence
A study in this week's BMJ finds that over two-thirds of women with the chest disease cystic fibrosis suffer urinary incontinence, yet are reluctant to seek help.

Rutgers biologist wins a $1.03 million, 5 year contract to study how microbes can help clean up Superfund sites
Rutgers microbiologist Lily Young of the university's Biotechnology Center for Agriculture and the Environment has been awarded a $1.03 million five-year contract to investigate how microbes can be used to detoxify arsenic and chromium contaminants at Superfund sites.

Acute zinc depletion affects homeostasis by reducing the rate of release from skeletal muscle
King et al. studied zinc homeostasis in 5 male subjects for 57 days.

Michael J. Fox Foundation grant awarded to UCSD Parkinson's researcher
The Michael J. Fox Foundation for Parkinson's Research has awarded one of its first-ever grants to UCSD for studies of a naturally occurring protein that has potential as a new Parkinson's disease therapy.

Rensselaer receives $600,000 for microelectronics research
Governor George E. Pataki announced June 19 that Rensselaer received $300,000 in funding to evaluate a new microelectronics insulating material that has the potential to double the processing speed of microchips.

People with rheumatoid arthritis have more periodontal disease
Swollen joints and missing teeth often go hand in hand, according to a new study in the Journal of Periodontology.

Dietary approaches to stop hypertension diet reduces cholesterol and long-term cardiovascular risk
Obarzanek et al. tested the effects of a blood pressure- lowering diet, the Dietary Approaches To Stop Hypertension (DASH), on lipid lowering in a cohort that was half female and more than half African American.

People with sleep apnea at higher risk of stroke
People with sleep-related breathing disorders, such as habitual snoring and sleep apnea, are at higher risk of suffering a stroke, according to a study by a Yale researcher published in the June issue of the journal Stroke.

Using lasers, biologists succeed in getting cells to change course
Using a beam of laser light only a few microns in diameter, University of North Carolina at Chapel Hill scientists have succeeded for the first time in getting such light to alter the course of a moving cell.

Mass media campaigns can alter beliefs about back pain
New research in this week's BMJ finds that mass media campaigns can alter people's beliefs about back pain, improve knowledge and attitudes among doctors and reduce compensation claims for back problems.

Oats are safe for celiac disease patients
Celiac disease, an inherited disorder characterized by an abnormal immune response to gluten that results in damage to the intestinal mucosa, requires a diet in which grains that contain gluten are carefully restricted.

Stress, infertility linked in study by Magee-Womens Research Institute
Increased levels of the stress hormone cortisol are clearly elevated in the bloodstream of child-bearing-aged women who have stopped menstruating, a senior researcher at the Magee- Womens Research Institute has found.

Transfusion mystery unraveled: Researchers link protein to fevers, immune complications
Patients who receive blood-platelet transfusions often spike fevers or develop life-threatening complications, and now researchers know why: A protein in the platelets escapes from platelet cells while they are in storage and ultimately plays a role in creating compounds that wreak havoc in the body.

Scientists reconcile opposing views of U.S. role in greenhouse gas problem
An international consortium of scientists has issued a revised estimate of the U.S. role in the worldwide accumulation of carbon dioxide in the atmosphere, a major cause of global warming.
