Nanowires highly ‘anelastic,’ research shows

At the nanoscale, familiar materials often take on unexpected properties. Researchers from Brown and NC State have shown that zinc oxide nanowires are highly anelastic, meaning they return to shape slowly after being bent, rather than snapping right back. Anelastic materials are good at dissipating of kinetic energy. This new finding suggest nanowires could be useful in absorbing shocks and vibrations.

Meeting to build community around Christianson Syndrome

Scientists and families from around the world will gather in The Woodlands, Texas, July 30 – Aug. 2 to build the community needed to find a treatment for Christianson Syndrome, a newly recognized genetic intellectual disability disorder in boys.

Review Indicates Cardio Exercise Benefits

Exercise examined:

Everyone knows that exercise generally helps the cardiovascular system, but much remains unknown about how the benefits arise, and what to expect in different people who exercise to improve their health. To gain a more precise understanding of how exercise improves health and whom it helps most, researchers, including Epidemiology doctoral student Xiaochen Lin, analyzed the results of 160 randomized clinical trials with nearly 7,500 participants.

Review indicates where cardio benefits of exercise may lie

A systematic review of 160 clinical trials of the cardiometabolic benefits of exercise shows which health indicators improve most with physical activity and for whom. For example, some of the benefits are greater for men, people under 50 and among those battling type 2 diabetes or other cardiovascular conditions.

Johnson, Europeans to study plant fertility evolution

Taking advantage of research progress and advanced gene sequencing technology, Brown University will join a consortium of European researchers for a three-year, $2.9-million study of how fertilization has evolved in flowering plants. A goal is to improve crop yields.
