If Only We Could See It In Real... Scientists have created one of the most detailed 3D reconstructions of a human cell ever produced. The visualization combines data from X-ray tomography, nuclear magnetic resonance (NMR), and cryo-electron microscopy to reveal the astonishing molecular complexity packed inside a single eukaryotic cell. What looks simple from the outside is actually an incredibly dense world of molecular machines, membranes, proteins and organelles all working together. One cell. An entire microscopic universe.
