Electron cryomicroscopy can yield near-atomic resolution structures of highly ordered macromolecular complexes. Often however some subunits bind in a flexible manner, have different symmetry from the ...
Two never-before-seen particles have just been detected at CERN’s Large Hadron Collider, the world’s largest particle accelerator, by the international LHCb collaboration. Known as Xi_b'- and Xi_b*-, ...
IN recent work on the attachment of radioactive particles to Aitken nuclei, we have been concerned with the sampling and subsequent examination by electron microscopy of Aitken nuclei in the ...
