Antihelium-4: Physicists nab new record for heaviest antimatter

(PhysOrg.com) -- Members of the international STAR collaboration at the Relativistic Heavy Ion Collider -- a particle accelerator used to recreate and study conditions of the early universe at the U.S. Department of Energy's ...

IceCube neutrino observatory nears completion

In December 2010, IceCube -- the world's first kilometer-scale neutrino observatory, which is located beneath the Antarctic ice -- will finally be completed after two decades of planning. In an article in the AIP's Review ...

Understanding quantum mechanics with active particles

Physicists led by Prof Raphael Wittkowski and Prof Uwe Thiele from the Institute of Theoretical Physics at the University of M√ľnster has developed a new model for the dynamics of systems consisting of many self-propelled ...

What comes after the Higgs boson

Ten years ago this week, two international collaborations of groups of scientists, including a large contingent from Caltech, confirmed that they had found conclusive evidence for the Higgs boson, an elusive elementary particle, ...

Targeting cancer at the nanoscale

Scientists from the Department of Nuclear Medicine and Tracer Kinetics at Osaka University developed a novel system for targeted cancer radiation therapy that uses gold nanoparticles labeled with astatine-211. Owing to the ...

Simulating nuclear cloud rise anywhere, anytime

For decades, understanding the behavior of a nuclear mushroom cloud was done with careful analysis of observations made during the testing era. Old photos, outdated film and incomplete weather data made precise calculations ...

Radioactive molecules may help solve mystery of missing antimatter

Stars, galaxies, and everything in the universe, including our own bodies, are comprised of so-called regular matter. Regular matter includes atoms and molecules, which are made up of tiny particles, such as electrons, protons, ...
