Accurate drug dosages with proton traps

Researchers at Linköping University, Sweden, have developed a proton trap that makes organic electronic ion pumps more precise when delivering drugs. The new technique may reduce drug side effects, and in the long term, ...

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 ...

Researchers establish crystal structure of gastric proton pump

The highly acidic environment in the stomach is essential for digestion. Furthermore, it acts as an important barrier to invasive pathogens. However, excessive stomach acidification leads to ulcers. Although this is not a ...

It´s a matter of gradients

Thermophoresis for the energy supply of early cells. NIM scientist Dr Christof Mast and his team suggest thermally driven formation of pH gradients and proton flux as source of chemical energy conversion in early stages of ...
