Antimatter Catches a Wave at SLAC

A study led by researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and the University of California, Los Angeles has demonstrated a new, efficient way to accelerate positrons, the antimatter opposites of electrons. The method may help boost the energy and shrink the size of future linear particle colliders – powerful accelerators that could be used to unravel the properties of nature’s fundamental building blocks.

Grenada, Spain's climate and layout is like that of many cities in the Mediterranean area, which has the highest occurrence of pollen allergies in the world. The researchers hope their efforts will lead to fantastic urban green spaces that don’t cause allergic reactions for 30% of the city’s population.

In early August, biologist Peter Ward returned from the South Pacific with news that he encountered an old friend, one he hadn’t seen in over three decades. The University of Washington professor had seen what he considers one of the world’s rarest animals, a remote encounter that may become even more infrequent if illegal fishing practices continue.

New Data From Antarctic Detector Firms Up Cosmic Neutrino Sighting

Researchers using the IceCube Neutrino Observatory have sorted through the billions of subatomic particles that zip through its frozen cubic-kilometer-sized detector each year to gather powerful new evidence in support of 2013 observations confirming the existence of cosmic neutrinos. The evidence is important because it heralds a new form of astronomy using neutrinos, the nearly massless high-energy particles generated in nature’s accelerators: black holes, massive exploding stars and the energetic cores of galaxies.
