18 host proteins play an important role during SARS-CoV-2 infection – two of them are particularly interesting. They could open up new ways to treat infections with SARS-CoV-2 and other RNA viruses. Graphics: SCIGRAPHIX / S. Westermann

Scientists from Würzburg and the US have charted the first global atlas of direct interactions between SARS-CoV-2 RNA and human host cells. This may provide a starting point for novel treatments.

The combination of different bioinformatics methods has brought new small proteins from salmonella to light.

Only one small protein needs to be missing and salmonellae are no longer infectious. This was discovered in a study in which the pathogens were re-analysed using bioinformatics.

Open trap of Dionaea muscipula with potential prey. Middle: basal part of a trigger hair, where action potentials are elicited in the sensory cells upon touch stimulation. During the late phase of the action potential, potassium ions need to be reimported into the sensory cells via KDM1 to enable the generation of consecutive action potentials.

The display of a smartphone reacts to finger pressure. The carnivorous Venus flytrap, on the other hand, even notices when a lightweight like a fly lands on it. Special genes make this possible.

The longer the sword of the male (bottom), the greater the chances of its bearer being interested by a female (top). In the swordtail fish (Xiphophorus hellerii), scientists have now identified the genetic basis of sword growth. (Image: Georg Schneider / University of Würzburg)

In many species all over the animal kingdom, males have eye-catching characteristics. Although often impractical, they are beneficial in finding a mate. Scientists have now mapped the genetic bases of such a male ornament in a fish.

Christina Felfe, Professor of Economics in Würzburg, has raised two million euros for her new project, which focuses on a socially relevant topic: dwindling social cohesion.

Sphingolipid expansion microscopy (ExM) of tenfold expanded cells infected with chlamydia. The bacterial membranes are marked green; the inner and outer membranes of the bacteria can be distinguished (c). Under (a) confocal laser scanning and under (b) structured illumination microscopy (SIM). Scale bars: 10 and 2 microns in the small white rectangles respectively.

For the first time ever, expansion microscopy allows the imaging of even the finest details of cell membranes. This offers new insights into bacterial and viral infection processes.
