About 17 years ago, J. Martin Laming, an astrophysicist at the U.S. Naval Research Laboratory, theorized why the chemical composition of the Sun’s tenuous outermost layer differs from that lower down...

Human gum cells as a test system for investigating interactions between resveratrol, bitter receptors and the release of inflammatory markers.

Resveratrol is a plant compound found primarily in red grapes and Japanese knotweed. Its synthetic variant has been approved as a food ingredient in the EU since 2016. At least in cell-based test systems, the substance has anti-inflammatory properties...

Researchers introduce a novel device concept towards high-efficient and low-voltage vertical organic lighting-emitting transistors. With the new device architecture and fabrication technology, the team paves the way for a broad application of efficient OLED active matrix displays.

In the group of Prof. Karl Leo, physicists, material scientists and engineers are working jointly on the development of novel organic materials and devices for high performance, flexible and possibly even biocompatible electronics and optoelectronics of the future. Increasing the performance of organic devices is one of the key challenges in their research. It was only last year, when the team headed by Dr...

Analysis of observations made by satellites in 2014 has revealed a long-lasting ‘space hurricane’ – a swirling mass of plasma several hundred kilometers above the North Pole, raining electrons instead of water.

Hurricanes in the Earth’s low atmosphere are known, but they had never before been detected in the upper atmosphere.

An international team of scientists led by Shandong University in China analysed observations made by satellites in 2014 to reveal a long-lasting hurricane, resembling those in the lower atmosphere, in the polar ionosphere and magnetosphere with surprisingly large energy and momentum deposition despite otherwise extremely quiet geomagnetic conditions.

The analysis allowed a 3D image to be created of the 1,000km-wide swirling mass of plasma several hundre...
