Nerve cells' powerhouse 'clogged' in Lou Gehrig's disease
By studying rodent models of the relatively rare inherited form of Lou Gehrig's disease and tissue samples from a patient with the condition, scientists have discovered the first evidence that damage to nerve cell powerhouses is directly responsible for these cells' death.

On two occasions, separated by four years and thousands of miles and in very different conditions, raindrops were measured at sizes similar to or greater than the largest ever recorded.

Carnivore species are predicted to be at increased extinction risk from human population growth
Research published online today in PLoS Biology reveals that many of the world's carnivores are at greater risk of extinction than previously thought.

UW study: Migrating birds offer insight into sleep
A study points the way to solving two of life's seemingly eternal but unrelated mysteries: how birds that migrate thousands of miles every year accomplish the feat on very little sleep and what that ability means for humans who are seriously sleep-deprived or face significant sleep problems.

Climate-based model to predict West Nile virus activity
Cornell University scientists are launching a full-scale study on the influence of climate on mosquito populations that transmit diseases such as West Nile virus to humans.

First medical test on CD gets good results
Ohio State engineers have successfully automated a particular medical test on a compact disc for the first time -- and in a fraction of the normal time required using conventional equipment.

Scientists discover key step in the development of nerve cells controlling autonomic functions
Scientists at the Montreal Neurological Institute at McGill University have discovered a gene that is necessary for the correct development of the part of the brain that controls autonomic functions such as heart rate, bronchial dilation and gut peristalsis.

Sleepless over Seattle: Migrating songbirds forgo sleep but keep their wits
Every spring and fall, billions of songbirds migrate thousands of miles.

Vioxx in high doses causes hypertension
Despite previous warnings, a substantial number of people continue to be prescribed high doses of Cox-2 inhibitors, rising risks of heart problems.

Africans take anti-HIV meds at a higher rate than many anticipated
Contrary to widespread assumptions, UCSF researchers have found that an HIV-infected African cohort successfully followed a medication regimen, taking almost all of the anti-HIV drugs as prescribed and at a rate as high or higher than observed in published studies of HIV-infected cohorts in rich countries.

Thalidomide's promising future in fighting cancer explored in Mayo Clinic proceedings
From the late 1950s to the end of 1961, thalidomide was a popular sedative and treatment for morning sickness until it was discovered to cause fetal malformations, which proved fatal within the first year of life in 40 percent of affected infants.

Rural African men claim AIDS as sign of masculinity
Many rural African men unknowingly claim to have AIDS, thinking it is an indicator of their masculinity and sexual prowess, says a University of Alberta researcher.

Hormone replacement therapy should start early
Women who begin hormone replacement therapy (HRT) before age 60 have a significantly lower risk of death than women not on hormones, finds a meta-analysis of 30 clinical trials by researchers at Cornell and Stanford universities.

APS recognizes Intel high school finalists for experiments in physiology
The American Physiological Society cited high school students who performed experiments on achilles tendon and relaxin; chlorine effects on outdoor swimmers; glucose homeostatis; restenosis and slow skeletal troponin T.

Growth study of wild chimpanzees challenges assumptions about early humans
A new study of wild chimpanzee growth rates suggests that early human evolution may have taken a different course than is widely believed.

NIAID expands West Nile virus treatment trial
The National Institute of Allergy and Infectious Diseases, one of the National Institutes of Health, has expanded its clinical trial of an experimental West Nile virus (WNV) treatment to about 60 sites throughout the United States and Canada.

Heart failure patients respond well to beta-blocker drugs
Heart failure patients who undergo beta-blocker therapy tolerated the treatment well and had less heart failure deterioration than placebo drugs, researchers at Yale School of Medicine and other institutions report in the July 12 issue of Archives of Internal Medicine.

Gene profiles could improve acute leukemia diagnosis and lead to better treatments
The results of a microarray analysis of genes from both children and adults with acute myeloid leukemia (AML) could significantly improve the ability to make accurate diagnoses and prognoses for the major genetic (molecular) subtypes of the pediatric form of this disease and lead to better treatments.

Comparing primate genomes offers insight into human evolution
Comparing primate genomes is an approach that can help scientists understand the genetic basis of the physical and biochemical traits that distinguish primate species.

Will the insured sacrifice to help cover the uninsured? New study suggests yes
It's one of the biggest questions facing Americans this election year: Will those who have health insurance be willing to sacrifice in order to insure the millions who don't?
