A "stink fight" between ring-tailed lemurs might be dead serious to them. But to observers, the scented struggle ranks among the more odd, even comical sights at the Duke University Primate Center — already renowned for the biological eccentricities of its exotic denizens.
Preparations for battle begin when male combatants load their "weapons" — vigorously rubbing their tails against their shoulders and between their wrists, infusing the fur with scent from glands there.
So armed — or tailed — they launch their attacks, feathery tails arched over their backs, ears flattened and squeaking warnings. They relentlessly flick their tails at one another until one of the adversaries comes to his scentses, gets the odiferous message and retreats. But until the research of Duke biologist Christine Drea and student Elizabeth Scordato, scientists had no idea what chemical messages were being wafted back and forth in such fights. More broadly, they have not understood the complex "language" of multiple scents that lemurs use to communicate a variety of messages from aggression to mating receptiveness.

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...
