A molecular movie has captured in detail the process of an anion transported across the cell membrane by a light-fuelled protein pump. Researchers have unravelled the mystery of how light energy ...

This release is available in German. Ions—charged atoms or molecules—play an important role in nature, in our bodies as well as for science and technology. It is often necessary to trap, remove, mask, ...

Rock salt separates into sodium and chloride ions when dissolved in water. These ions can cause damage to the inner workings ...

The activation of taste receptors by various food molecules triggers specific pathways, resulting in the sensation of taste. The association of chloride ion, a component of table salt, with a sweet ...

Many bacteria and unicellular algae have light-driven pumps in their cell membranes: proteins that change shape when exposed to photons such that they can transport charged atoms in or out of the cell ...
