Gaea is cool and everything, but what about fluvial erosion in #Blender with #GeometryNodes?

The concept rather simple:
- spawn points somewhere
- calculate a movement vector with ( N x (0,0,-1) ) x N, where N is the normal vector, sampled from the mesh surface (its a double cross product)
- update the points in a simulation zone
- accumulate the point proximity in a per-face attribute for the mesh. This requires a high res mesh
- optionally displace the mesh

A fantastic cosmic web #geonodes setup for Blender. It is useful for creating superstructures resembling galactic filaments – that actually run super fast.

Push and throw proteins around in #webxr: https://akodiat.github.io/vrotein/. Act out your feelings towards the covid spikes protein, or any other PDB! The dynamics uses a simple spring network, inspired by @bradyajohnston (but still in need of parameterisation). Also thanks to @cabanier for helping me use unbounded spaces.

another friend is resigning from his postdoc position to take up an independent consulting-ish career. there was no space for academia for his unique skillset (it did not lead to papers or grants)

Academic journals can price gouge because universities are relieved to be able to outsource performance reviews of PhD students and faculty to them

More value-add from the journals: 2 million papers with DOIs are not accessible anymore. Fire out the paper and forget.

Millions of research papers at risk of disappearing from the Internet

An analysis of DOIs suggests that digital preservation is not keeping up with burgeoning scholarly knowledge.

#MolecularNodes is teaming up with the folks at MDAnlasis to offer a potential #GSOC project.

If you are interested in improveing the integration of #Blender3d and #MDAnalysis for better visualisations of your analysis, check out the blog post for how to get involved: https://www.mdanalysis.org/2024/02/27/gsoc2024/
