What Goes Around Is Really Round: “Improved measurement of the shape of the electron”

The big physics story of the week is undoubtedly the new limit on the electric dipole moment (EDM) of the electron from Ed Hinds’s group at Imperial College in the UK. As this is something I wrote a long article on for Physics World, I’m pretty psyched to see this getting lots of media attention, […]

Protons: Even Smaller Than We Thought

The big physics story at the moment is probably the new measurement of the size of the proton, which is reported in this Nature paper (which does not seem to be on the arxiv, alas). This is kind of a hybrid of nuclear and atomic physics, as it’s a spectroscopic measurement of a quasi-atom involving […]
