Keeping predators at bay with flashing lights and loud noises instead of bullets
When wolves and other large carnivores threaten people and livestock, wildlife managers often resort to killing them. But now theres hope for a non-lethal solution to controlling carnivores. New research shows that movement-activated guards with strobe lights and sound recordings can help keep wolves and bears away.
"High-technology devices are much more expensive, complicated and limited in effectiveness than a single bullet from a high-powered rifle, but they also allow a predator to live - surely the goal of conservation," say John Shivik of the United States Department of Agriculture, Wildlife Services, National Wildlife Research Center and Utah State University in Logan; Adrian Treves, who did this work while at Conservation International in Madison, Wisconsin, and is now at the Wildlife Conservation Society in Bronx, New York; and Peggy Callahan of the Wildlife Science Center in Forest Lake, Minnesota.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
