Kennewick Man closely related to Native Americans, geneticists say
The 8,500-year-old skeleton found in Washington, in 1996, has been the subject of a dispute. Now, genetic analyses of the ancient DNA suggest he is an ancestor of present-day Native Americans.

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.
-
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.
-
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.
-
Higher concentration of physicians 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.
-
Carla Shatz shares $500,000 Gruber Prize
Carla Shatz has uncovered mechanisms that the brain uses to select which connections to strengthen or prune back as brain circuits form.
-
Wild chimps teach scientists about gene that encodes HIV-fighting protein
Part of a gene variant present in some wild African chimps is nearly identical to a section of an analogous gene version found in HIV-infected humans who are uncharacteristically slow to progress to full-blown AIDS.
-
Researchers tie unexpected brain structures to creativity — and to stifling it
A new study is the first to directly implicate the cerebellum in the creative process. As for the brain’s higher-level executive-control centers? Not so much.
