In the March issue of Frontiers in Ecology and the Environment, Max Moritz (University of California, Berkeley), Jon Keeley (US Geological Survey and University of California, Los Angeles), Edward Johnson (University of Calgary) and Andrew Schaffner (Cal Poly State University, San Luis Obispo) present research that challenges some of the assumptions for managing fire-prone regions. With "Testing a basic assumption of shrubland fire management: how important is fuel age?," the authors suggest natural fire regimes, such as those found in southern California, are "more driven by extreme weather conditions" than age-related traits of the regions plant life.
Examining the fire history of coastal and southern California shrublands, the group discovered that the majority of shrublands risk of burning was fairly steady, at about 2.7 percent each year.
"Historical fire patterns and quantitative measures of hazard therefore refute the common assumption that fire probabilities in shrublands are strongly driven by vegetation age, and that large fires are necessarily caused by a buildup of older fuels," according to the study.

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...
