Filling a Gap in 3D Images of Molecules within a Cell (IMAGE)
Caption
With a technique called cryoelectron tomography, scientists can create detailed 3D images of cells, such as this Caulobacter bacterium, and highlight their components - in this case, the cell membranes (red and blue), protein shell (green), protein factories known as ribosomes (yellow) and storage granules (orange). But until now, smaller structures and individual molecules could not be identified and precisely located within these images. A new imaging technique developed at Stanford fills this gap, revealing small molecules that are not visible here.
