Mayo collaboration finds source of breast drug side effect

Mayo Clinic researchers and their international colleagues have discovered genetic variants that lead to severe arthritis for a subset of women when taking aromatase inhibitors to treat their breast cancer. This serious side effect is so painful that many women halt their lifesaving medication. The findings appear today in the online issue of Journal of Clinical Oncology.

Pan-STARRS discovers its first potentially hazardous asteroid

The Panoramic Survey Telescope & Rapid Response System (Pan-STARRS) PS1 telescope has discovered an asteroid that will come within 4 million miles of Earth in mid-October. The object is about 150 feet in diameter and was discovered in images acquired on September 16, when it was about 20 million miles away.

Pine-bark extract has no effect on blood pressure, study finds

Add pine-bark extract to the list of dietary supplements that don't live up to their promises of improved health. A new study from the Stanford University School of Medicine shows that pine-bark extract had no effect in lowering blood pressure or reducing other risk factors for heart disease.

Probing Question: What is a Near Earth?

In the 1997 movie "Contact" (based on the novel by Carl Sagan), actress Jodie Foster plays an astrophysicist devoted to SETI -- the Search for Extra-Terrestrial Intelligence. Despite doubting colleagues, she vigilantly monitors signals from radio telescopes aimed at thousands of nearby sun-like stars, hoping to receive a message from alien life forms. While the large dish telescope in the movie is...

Right or left? Brain stimulation can change which hand you favor

(PhysOrg.com) -- Each time we perform a simple task, like pushing an elevator button or reaching for a cup of coffee, the brain races to decide whether the left or right hand will do the job. But the left hand is more likely to win if a certain region of the brain receives magnetic stimulation, according to new research from the University of California, Berkeley.

Risk model based on Get with the Guidelines analysis can help

Using data from more than 270,000 hospital stroke admissions, scientists have identified how to predict which patients are at greatest risk of dying in the hospital after stroke. Before their study, well validated models to predict in-hospital death risk after stroke were lacking, the researchers reported in Circulation: Journal of the American Heart Association.

Solar cells thinner than wavelengths of light hold huge power potential

(PhysOrg.com) -- Ultra-thin solar cells can absorb sunlight more efficiently than the thicker, more expensive-to-make silicon cells used today, because light behaves differently at scales around a nanometer, say Stanford engineers. They calculate that by properly configuring the thicknesses of several thin layers of films, an organic polymer thin film could absorb as much as 10 times more energy...

Wider statin use could be cost-effective preventive measure, study finds

A new analysis suggests that broader statin use among adult patients may be a cost-effective way to prevent heart attack and stroke. The Stanford University School of Medicine study also found that using a popular test - a screening for high sensitivity C-reactive protein, or CRP - to identify patients who may benefit from statin therapy would be cost-effective, but only under certain scenarios.

Family, culture affect whether intelligence leads to education

Intelligence isn't the only thing that predicts how much education people get; family, culture, and other factors are important, too. A new study published in Psychological Science, a journal of the Association for Psychological Science, compares identical and fraternal twins in Minnesota and Sweden to explore how genetic and environmental factors involved in educational differ in countries with...
