A smashing discovery Article by Tracey Bryant, adapted from IceCube collaboration Photos courtesy of Frank Schroeder and the IceCube Collaboration March 10, 2021 IceCube detector helps prove 60-year-old theory An electron antineutrino races to Earth from outer space at nearly the speed of light, carrying 6.3 petaelectronvolts (PeV) of energy. Deep in the ice sheet at the South Pole, this high-energy particle smashes into an electron and produces another particle, which quickly decays into a shower of secondary particles. The explosion of l...

Deep inside the ice sheet at the South Pole, it smashed into an electron and produced a particle that quickly decayed into a shower of secondary p...

Oak Ridge Today Posted at Praveena Krishnan The National Science Foundation Office of Polar Programs has awarded ORAU a collaborative research grant to study greenhouse gas emissions in the Arctic. The award is valued at $581,829. The grant will be used to study local and regional emissions of isotopes of methane and carbon dioxide. Methane and carbon dioxide are two greenhouse gases. Greenhouse gases can help raise the Earth’s temperature, changing the climate and causing other significant changes. (Isotopes are different forms of an element that have equal numbers of protons but differ...
