Authors say results could have major impacts on ’green’ certification programs
A study by a scientist from the New York-based Wildlife Conservation Society has revealed how Africa’s giant mahoganies, the ancient trees driving the tropical logging industry, require specialized, poorly understood soil conditions – results that could have huge implications on how Africa’s tropical forests are managed.
The study, appearing in the latest issue of the journal Ecology, looked at four mahogany species in Dznagha-Sangha Dense Forest Reserve, a 1,700 square-mile region in Central African Republic. The authors found that that three of the four species required specialized soils – those with a particular combination of plant nutrients - and were restricted to these sites within the forest. Previous analyses of soils with respect to the distribution of these and other tropical tree species have looked at things like topography to infer soil conditions, completely missing the importance and complexity of soil chemistry.

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...
