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.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
