Closing the Rural Health Gap: Media Update from RWJF and Partners on Rural Health Disparities

nrhd-logo2017.png

Rural counties continue to rank lowest among counties across the U.S., in terms of health outcomes. A group of national organizations including the Robert Wood Johnson Foundation and the National 4-H Council are leading the way to close the rural health gap.

Scientists See Fireworks From Atoms at Ultra-Low Temperatures

BoseFireworks.jpg

Scientists aren’t normally treated to fireworks when they discover something about the universe. But a team of University of Chicago researchers found a show waiting for them at the atomic level—along with a new form of quantum behavior that may someday be useful in quantum technology applications.

Quantum Dots Visualize Tiny Vibrational Resonances

APL017739-Carter-InGaAsDots-RL.jpg

When laser light is used to drive the motion of a thin, rigid membrane, the membrane vibrates in resonance with the light. The resulting patterns can be visualized through an array of quantum dots, where these tiny structures emit light at a frequency that responds to movement. The advance is reported this week in a cover article of Applied Physics Letters.
