Cell Membranes in Super Resolution

Würzburg, Germany — Expansion microscopy (ExM) enables the imaging of cells and their components with a spatial resolution far below 200 nanometres. For this purpose, the proteins of the sample under...

Tackling Metabolic Complexity

Munich, Germany — Metabolic robustness, the ability of a metabolic system to buffer changes in its environment, is not always a welcome feature for microbiologists: it interferes with metabolic engineering...

Worms Reveal Why Melatonin Promotes Sleep
