First simulation of a full-sized mitochondrial membrane
Posted on:08 May 2020

Scientists from the University of Groningen have developed a method that combines different resolution levels in a computer simulation of biological membranes. Their algorithm backmaps a large-scale model that includes features, such as membrane curvature, to its corresponding coarse-grained molecular model. This has allowed them to zoom in on toxin-induced membrane budding and to simulate a full-sized mitochondrial lipid membrane. Their approach, which was published in the journal Nature Communications on 8 May, opens the way to whole-cell simulations at a molecular level.

Posted on:03 March 2020

The spread of antibiotic resistance is partly due to the ability of bacteria to pick up DNA from their surroundings. A new study, which started at the University of Groningen, showed that drugs blocking this ability (which is called ‘competence’) in the bacterium Streptococcus pneumoniae can indeed stop the spread of resistance in mice.
