In the Caribbean Sea, coral reefs -- those gorgeous, eye-popping, fish-nourishing, ship-scraping biological wonders that are among the regions crown jewels -- continue to die rapidly, a University of North Carolina at Chapel Hill biologist says. Their future looks bleak.
Dr. John Bruno, assistant professor of marine sciences at UNC, and colleagues at other U.S. universities, believe they have identified one reason why. Results of field experiments they conducted off Mexicos Yucatan Peninsula suggested that chemical nutrients washed and dumped into the sea can increase the severity of coral diseases.
A report on the findings appears in the December issue of the journal Ecology Letters, which is expected to be posted online Nov. 26. Besides Bruno, authors are Drs. Laura E. Petes of Oregon State University, C. Drew Harvell of Cornell University and Annaliese Hettinger of California State University in Northridge.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
