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*-, ...

When most of us picture an atom, we think about a small nucleus made of protons and neutrons orbited by one or more electrons. We view these electrons as point-like while rapidly orbiting the nucleus.
