Electron still spherical despite efforts to prove otherwise

Artist's representation, an electron travels between two lasers in an experiment. The electron is spinning about its axis as a cloud of other subatomic particles are constantly emitted and reabsorbed.

Despite increasingly sensitive measurements, the electron has no dipole moment that would hint at exotic new particles

The most sensitive measurements ever performed to find irregularities within the electron’s charge – and therefore hints at of-yet unknown particles that might explain the nature of dark matter – have come up with nothing.
