Laura Nielsen for Frontier Scientists – Recent research published in Nature Geoscience states that the largest contributors to warming in the Arctic are the region’s distinct surface temperatures coupled with the Arctic atmosphere’s prevailing vertical temperature structure. The research suggests that diminished snow and melting ice cover, previously thought to have the largest impact on […]

Update: Comet ISON beyond the Sun
Laura Nielsen for Frontier Scientists – Last Thursday, while many gathered with loved ones for Thanksgiving, a frozen ball of ice and rock was hurtling towards the Sun reaching speeds of 225 miles/second [360 kilometers/second]. A fleet of solar-observing spacecraft had their instruments aligned, and experts were on hand to watch what unfolded. We wondered […]
Comet ISON approaches the Sun
Laura Nielsen for Frontier Scientists – Our patch of universe has a visitor from afar. Comet C/2012 S1 (ISON), or Comet ISON, has astronomers across the world training telescopes and eager eyes on outer space. Don Yeomans, manager of NASA’s Near-Earth Object Program Office, watches for objects whose orbits come close to Earth. He says ISON […]
ARSC Fish: CRAY Supercomputer Enables Scientific Discovery
Liz O’Connell for Frontier Scientists – Fairbanks, Alaska, November 6, 2012 – The Arctic Region Supercomputing Center at the University of Alaska Fairbanks has a new CRAY Supercomputer Called FISH. As ARSC transitions from a centralized machine to a strategically upgradeable hybrid system, they advance scientific discovery. It is a large scale upgrade to benefit research. Scientists who use […]
