Plant gene discovery could enhance plant growth, reduce fertilizer needs and phosphate pollution
Scientists at the Boyce Thompson Institute for Plant Research at Cornell University have uncovered the genes that enable plants to interact with beneficial soil dwelling fungi and to access phosphate delivered to the roots by these fungi -- a first step, they say, toward enhancing the beneficial relationship for crop plants , while reducing fertilizer use and phosphate pollution in the environment.

Moral choices made during the Holocaust provide lessons for today
Pictures of brutality pervade the news - Los Angeles police officers allegedly beating a suspect, American soldiers abusing Iraqi prisoners, Islamic militants beheading hostages.

LICR/UCSD team solves mystery of centromeres
Researchers at UCSD School of Medicine have solved one of genetics' mysteries - how a segment of protein on each of the body's DNA-carrying chromosomes is able to form a rigid structure called a centromere, leading to proper cell division and the faithful inheritance of genes.

UNC researchers awarded $8.65 million from National Institute on Aging
A team of scientists at the University of North Carolina at Chapel Hill School of Medicine has been awarded a federal grant of $8.65 million to investigate the molecular basis of blood vessel aging and its role in the development of vascular disease, including heart attack.

Condom use decreases pelvic inflammatory disease recurrence
Consistent condom use significantly decreases the risk for a common and serious infection of the female upper genital tract called pelvic inflammatory disease (PID), according to a study from the University of Pittsburgh's Graduate School of Public Health.

NASA grant to tap lunar resources
Florida Tech associate professor of chemical engineering, Dr. Jonathan Whitlow, received a grant of nearly $50,000 from NASA to develop computer models that can lead to producing propellants from the lunar regolith, or rock mantle.

July/August 2004 Annals of Family Medicine tip sheet
The July/August 2004 Annals of Family Medicine focuses on patient safety.

Why athletes get injured
Some sportspeople are more prone to injury than others, and it's all to do with combinations of movement rather than fitness.

Casanova or caveman: Scientists isolate nerve cells that choreograph male fly's courtship behavior
Stanford University scientists have discovered that the elaborate courtship ritual of the male fruit fly is choreographed by a bundle of about 60 nerve cells.

2.8 percent of the US population suffers from excessive sweating
Hyperhidrosis, or excessive sweating, affects a much larger proportion of the U.S. population than previously reported, according to new research by a Saint Louis University dermatologist.

Forest fire sensor inspired by nature
Zoologists at the University of Bonn have taken an important step towards low-cost and highly sensitive infrared sensors that may once monitor large forest areas and trigger an early warning in the event of fire.

Scientists finger surprise culprit in spinal cord injury
ATP, the vital energy source that keeps our body's cells alive, runs amok at the site of a spinal cord injury, pouring into the area around the wound and killing the cells that normally allow us to move.

Couples live together for convenience, not to test marriage
Many couples who move in together don't do it with marriage in mind, a small study of New York City residents suggest.

Epilepsy: Signals 'brake' in brain impaired
Normally specific ion channels absorb the neuronal activity. In rats suffering from epilepsy, however, this signals brake seems impaired: they have far fewer functioning ion channels than healthy rats.

Brookhaven lab biophysicist F. William Studier wins R&D 100 award
F. William Studier, a biophysicist at the U.S. Department of Energy's Brookhaven National Laboratory, has won a 2004 R&D 100 award for developing a new process that simplifies the production of proteins in the widely used T7 gene expression system.

Advanced energy storage technologies offer economic and energy-efficient back-up power options
Back-up power users such as manufacturers and utility providers are reluctant to move to advanced energy storage technologies from traditional lead-acid batteries.

U of T research answers key question in biochemistry
U of T post-doctoral fellow Dmitry Korzhnev and his supervisor, Professor Lewis Kay of the Department of Biochemistry, become the first researchers to characterize at an atomic level of detail the intermediate -- or substructure -- that forms as a protein folds to its 3-D state.

Study shows safe, effective therapy for previously untreated patients with HIV & hepatitis C
An international study with nearly 900 patients co-infected with Human Immunodeficiency Virus (HIV) and hepatitis C virus (HCV) has shown that HCV can be treated effectively and safely, without compromising the patient's HIV therapy.

American adults feel sad, blue, or depressed about 3 days a month
U.S. adults spent an average of three days a month feeling

Researchers identify better hepatitis C treatment for people with HIV
The preferred treatment for hepatitis C, peg-interferon and ribavirin, is safe for people who are also infected with HIV, according to a new study in the July 29 issue of The New England Journal of Medicine. Moreover, this treatment proved superior for the treatment of hepatitis C virus (HCV) in HIV-coinfected persons when compared with the previously accepted treatment, standard interferon and ribavirin.

New Resilience Centre launched by Cranfield University and the Defence Academy of the UK
Cranfield University at Shrivenham, in partnership with the Defence Academy of the UK, has launched its new Resilience Centre which aims to provide co-ordinated management advice and training on risk and security and resilience matters.

UCI study reveals gene linked to breast cancer can suppress tumors
A UC Irvine researcher has found a novel tumor- suppressor function for a gene that, when mutated, often triggers breast cancer in women.
