Systematic analysis of biomolecular conformational ensembles with PENSA Atomic-level simulations are widely used to study biomolecules and their dynamics. A common goal in such studies is to compare simulations of a molecular system

Molecular simulations or AI models produce ever larger and more complex datasets. Comparing different conditions to find meaningful patterns is a bottleneck for many projects.

We address this with PENSA, a flexible open-source analysis library.

Now out in JCP:

🧪 #CompChem

Nuclear pore permeability and fluid flow are modulated by its dilation state Hoffmann et al. describe within cells how the Dictyostelium discoideum nuclear pore complex structure constricts and dilates as a consequence of osmotic stress. Based on their experimental findings, they propose a hydrodynamics model and quantify fluid flow across nuclear pore complexes under conditions when nuclei change their volume rapidly.

Exciting work by Martin Beck’s group @mpibp.bsky.social providing further evidence for nuclear pores responding to mechanical stress. The work includes some nice modeling estimating the fluid flow across nuclear pores as a function of (osmotic) pressure.
