🌱 Using ‘compelling’ methods, including
#CryoET
, researchers mapped spinach thylakoid membranes at single-molecule precision, revealing how photosynthetic complexes are organised and settling long-standing debates on chloroplast architecture.

Better ML for cryo-ET starts with better benchmarks. We built a phantom cryo-ET dataset (~500 tomograms) + hosted a Kaggle challenge. The result: community models beat expert tools. Read more in the
