Some heartburn drugs may boost risk of heart attack, study finds A data-mining study has found an association between the use of proton-pump inhibitors, which account for 100 million prescriptions per year in the United States alone, and the likelihood of incurring a heart attack down the road.

In Kenya, program changes male attitudes about sexual violence, study finds Young men and teenage boys participating in a program developed by No Means No Worldwide had more positive views toward women and less belief in rape myths, a study found.

Toothed whales have survived millions of years without key antiviral proteins, researchers find Two genes that defend against many viral infections were rendered nonfunctional in toothed whales more than 33 million years ago, a new study asserts.

Scientists find genetic underpinnings of functional brain networks seen in imaging studies Imaging studies have delineated brain networks consisting of discrete brain regions acting in synchrony. This view of the brain’s functional architecture has now been confirmed by a study showing coordination at the genetic level as well.

Molecular cause of heart condition identified by researchers The beta adrenergic pathway is dysfunctional in dilated cardiomyopathy. Now, researchers have learned how a mutation that causes the disease affects the pathway, and how to mitigate its effects.

Higher concentration of physician groups could increase medical costs, researchers say Orthopedic surgeons in concentrated markets charged 7 percent more for knee replacements than physicians in less concentrated markets, a new study shows.

Discovery of molecular pathway could lead to pancreatitis treatments New research could lead to pharmacological treatments for chronic pancreatitis, a severe and currently untreatable disease.
