Scientists at the UK's National Physical Laboratory and the Cavendish Laboratory of Cambridge University have found a new way to control the movement of individual electrons -- they are making them ride the crests of energy waves like surfers.
...
NPL’s method involves creating
oscillating waves of electro-static force which flow like the surf
rolling into a beach. A single electron is placed on the crest of each
wave and the electro-static waves are then focused in a particular
direction or at a particular object.

Physicists discover 'triple-scoop' baryon
Physicists of the DZero experiment at the Department of Energy's Fermi National Accelerator Laboratory have discovered a new heavy particle, the Ξb (pronounced "zigh sub b") baryon, with a mass of 5.774±0.019 GeV/c2, approximately six times the proton mass.

Matter Flashed at Ultra Speed
Using a robotic telescope at the ESO La Silla Observatory, astronomers have for the first time measured the velocity of the explosions known as gamma-ray bursts. The material is travelling at the extraordinary speed of more than 99.999% of the velocity of light, the maximum speed limit in the Universe.

"The next question is which kind of 'engine' can accelerate matter to such enormous speeds," says Covino.
