After analyzing DNA in elephant dung, the authors of a new study in Animal Conservation found that the countrys northeast elephant population is actually made up of two genetically distinct groups separated by the Brahmaputra River. An earlier study by the same authors showed that the southern populations are also genetically distinct, separated by the Palghat Gap.
Researchers find one population actually two; suggest strategies for future elephant conservation
Researchers in India and from The Earth Institute at Columbia University have discovered that one of the few remaining populations of Asian elephants in India is actually two genetically distinct groups. The results of the study, which appear in the current issue of the journal Animal Conservation, could have far-reaching implications in conservation plans for the endangered elephants as well as other species on the Subcontinent.
Prithiviraj Fernando, a post-doctoral researcher at the Center for Environmental Research and Conservation (CERC), and Don Melnick, executive director of CERC, together with colleagues from the Centre for Ecological Science at the Indian Institute of Science collected dung samples from nearly 300 wild Asian elephants and 30 captive elephants for which reliable capture information existed. They then examined DNA from the samples and found that, of the distinct populations found in India, the groups that inhabit the forests in the northeast of the country is actually composed of two genetically distinct populations separated by the Brahmaputra River.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

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...
