Research breakthroughs by two international groups at CERN, one on trapping antihydrogen and one on a new technique for extracting an antihydrogen beam, have been selected as the 2010 "Breakthrough of the Year" by Physics World, a magazine of the Institute of Physics (IOP). Both breakthroughs mark major advances in physics, opening up new avenues in antihydrogen-based research. The Atomic Physics Laboratory at the RIKEN Advanced Science Institute (ASI), headed by Distinguished Senior Scientist Yasunori Yamazaki, has played an essential role in both antihydrogen projects.
