Scientists have made an unprecedented close examination of the electron, providing fascinating new insights into the nature of particles, energy and forces at infinitesimally small scales.

A collaboration led by researchers from Yale, Harvard and Northwestern universities found that the electron’s charge has a spherical shape, according to a study published in the journal Nature.

“If we had discovered that the shape wasn’t round, that would be the biggest headline in physics for the past several decades,” Gerald Gabrielse, a professor in the department of physics and astronomy at Northwestern, director of the Center for Fundamental Physics at Low Energy and an author of the study, said in a statement.
