Mayo Clinic study: Echocardiogram spots risk of valve narrowing, stroke
Standard echocardiograms which image the heart using ultrasound waves -- much like the ultrasound images used during pregnancy to monitor fetal development -- can be used as a screening tool to spot aortic valve abnormalities and to identify people at high risk for stroke and heart valve disease, according to a Mayo Clinic study published in September's Journal of the American College of Cardiology.

Stigma and global health: Developing a research agenda
To explore the relationship between stigma and public health, examine the social and cultural determinants of stigma, explore how stigma prevents people from seeking or getting treatment for disease, and determine future research opportunities, the Fogarty International Center, in partnership with other National Institutes of Health Institutes and Offices, U.S. agencies, and domestic and international organizations, announces a major international conference oriented toward developing a research agenda that will lead to the mitigation of the impact of stigma on individuals and societies.

Chemical warfare isn't just for humans. Some marine organisms have a knack for it, too, and chemists at Texas A&M University think the sea-life version might have medical applications.

Virginia Tech part of group arriving at major physics measurement
Virginia Tech physicists, in collaboration with others on the Belle Experiment at the Japanese National Laboratory for High Energy Physics (KEK), have obtained a measurement that shows that, to a very high degree, there is an asymmetry in the behavior of matter and anti-matter and that the difference is consistent with the prediction of the Standard Model Theory of Particle Physics.
