As published today in Nature: Improved limit on the electric dipole moment of the electron (free to view) and summarized on Live Science.

They improve on the previous measurements by an order of magnitude, and (very briefly) reason that this gives problems to a lot of Standard Model extensions as they predict (virtual) particles that couple to the electron and should show up in the EDM - and at the very least should constrain these particles to very high energies.

What theories and how do these new constraints on the theories' particle energies put limits on them?

For example, I'm not very knowledgable on the experimental limits on super-symmetric extensions but I think I've seen graphs illustrating that their possible particle energies are already getting severely constrained..
