"New analysis shows a way to self-propel subatomic particles"
EXCERPT - ... physicists at MIT and Israel's Technion have found that subatomic particles can be induced to speed up all by themselves, almost to the speed of light, without the application of any external forces ... "The electron is gaining speed, getting faster and faster," Kaminer says. "It looks impossible. You don't expect physics to allow this to happen."

Interesting, but I think, perhaps, it is a rediscovery.
Several papers have shown how highly oscillatory (but with slowly moving envelop) wavefunctions can attain high kinetic energy.
Also, phenomena like superoscillations, can cause "hot spots" and energy foci in fields.
