HIV/AIDS Education in America (MWV14)

submitted by: MicrobeWorld
In this episode of MicrobeWorld Video we ask some leading researchers, education specialists, and public health officials about the state of HIV/AIDS education in America and ideas they have to support the teaching of microbial evolution using the latest HIV/AIDS research ó all while instilling innovative prevention strategies. Filmed at a forum for educators on February, 11, 2008 at the Koshland Science Museum in Washington, D.C. and at San Diego State University, this episode features...

Homogenization of northern U.S. Great Lakes forests due to land use

submitted by: edtech-isu
Human land use of forested regions has intensified worldwide in recent decades, threatening long-term sustainability. Primary effects include conversion of land cover or reversion to an earlier stage of successional development. Both types of change can have cascading effects through ecosystems; however, the long-term effects where forests are allowed to regrow are poorly understood. We quantify the regional-scale consequences of a century of Euro-American land use in the northern U.S. Great...

Resonance: Radio, Wineglasses, Opera Singers and Cycles

submitted by: RayTomes
Resonance is the quality of transmitting even tiny signals between systems that are tuned to the same frequency. Given that cycles of common period are found pervading many different disciplines, perhaps an explanation may be found in resonance. An example is the 160 minute (and associated 80 minute cycle) cycle, found in biological systems, outer planetary spacings, the rotation rates of planets, asteroids and binary stars, solar oscillation and flux and galactic cores. A cosmic pervading...
