Ion and lipid transporters specialize for their niche

Cell viability requires that a variety of functions at the cell membrane are maintained properly. P-type ATPases translocate substrates across the membrane, and they have evolved into different types taking care of specific ...

'Bite' defects revealed in bottom-up graphene nanoribbons

Graphene nanoribbons (GNRs), narrow strips of single-layer graphene, have interesting physical, electrical, thermal, and optical properties because of the interplay between their crystal and electronic structures. These novel ...

Dual brake on transport protein prevents cells from exploding

A high concentration of salt or sugar in the environment will dehydrate microorganisms and stop them from growing. To counter this, bacteria can increase their internal solute concentration. Scientists from the University ...

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-Universit├Ąt ...
