A bit of a moment here. The image in the article is NOT the same as an Electron Microscopy image: its a 3D render of a structure, not a photograph, or a record of EM scanning.<p>The PNAS reference is 404.<p>Basically, this looks like AI slop: it doesn't show the improved image it shows a render of hypothetical structure, and it doesn't reference the paper it references a pnas number which is 404.<p>This is the correct PNAS reference: <a href="https://www.pnas.org/doi/10.1073/pnas.2312905120" rel="nofollow">https://www.pnas.org/doi/10.1073/pnas.2312905120</a><p>The images in there make a lot more sense: they look like Xray crystallography 2D projections of the 3D surface which has been EM scanned.<p>(when I looked)
