Mystery of giant proton pump solved

Mitochondria are the powerhouses of our cells, generating energy that supports life. A giant molecular proton pump, called complex I, is crucial: It sets in motion a chain of reactions, creating a proton gradient that powers ...

A new way of modulating color emissions from transparent films

Scientists are looking at luminescent transparent films for use in energy-efficient displays (such as LED screens) and other applications, and the possibilities it opens up for advancing methodologies in several fields of ...

New kind of interaction discovered in hydrogen-producing enzymes

Hydrogenases can convert hydrogen just as efficiently as expensive platinum catalysts. In order to make them usable for biotechnological applications, researchers are deciphering how they work in detail. A team from Ruhr-Universität ...

Researchers explore pollen fertilization mechanisms

A group of researchers from four countries has worked out exactly how a pollen tube, the plant cell that emerges from a grain of pollen, grows up to a thousand-fold to reach an ovule deep inside the flower. The key to this ...
