Cryo-electron microscopy breaks a key barrier
I'm a structural biologist that uses CryoEM to study archeal viruses. I'd be happy to answer any questions about CryoEM.<p>I did want to point out though that this title is misleading. The researchers didn't get an image of an atom. Instead, they reconstructed hundreds of thousands of images of the protein to determine where the atoms are almost exactly. So there's no actual image that shows an atom, as cool as that would be.
