Scientists Zap Diamond With Laser to Record Quantum Behavior
2014-08-27 15:55:47| TechNewsWorld
Researchers recently developed a technique to record the quantum mechanical behavior of one electron in a nanoscale defect in diamond. The team used ultra-fast pulses of laser light both to control the defect's entire quantum state and to observe how the state of one electron in the defect changes over time. "This experiment uses a 'trapped' electron," said team leader David Awschalom.

MIT Scientists Explain How Global Warming is 'Temporarily' Cooling Antarctica
2014-08-25 16:07:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Massachusetts Institute of Technology researchers explain why global warming has led to Arctic losing sea ice, but the same has not been observed in Antarctica. Over the past few years, Arctic has shown considerable reduction in sea ice levels due to global warming. However, Antarctica has cooled and has even gained some ice recently. A new study suggests that ocean circulation can explain why the polar regions have different reactions towards rise in earth's temperature. John Marshall, the...

Scientists Dont Think Rick Scott is Climate Literate
2014-08-25 10:08:00| Climate Ark Climate Change & Global Warming Newsfeed
Ring of Fire: On the subject of climate change, Florida Gov. Rick Scott usually parrots the same Im not a scientist excuse on which many of his Republican colleagues rely. Several scientists decided to help Scott out, and sent him a letter in June, saying they would like the opportunity to explain what is at stake for [Florida]. Scott met with five scientists in his office last week to discuss climate change, but afterwards, the scientists said they dont think that he really got the message. At least...

Methane Is Discovered Seeping From Seafloor Off East Coast, Scientists Say
2014-08-24 20:32:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: Scientists have discovered methane gas bubbling from the seafloor in an unexpected place: off the East Coast of the United States where the continental shelf meets the deeper Atlantic Ocean. The methane is emanating from at least 570 locations, called seeps, from near Cape Hatteras, N.C., to the Georges Bank southeast of Nantucket, Mass. While the seepage is widespread, the researchers estimated that the amount of gas was tiny compared with the amount released from all sources each year. In a paper...

Scientists warn about 'precarious' state of world's primary forests
2014-08-24 06:53:00| Climate Ark Climate Change & Global Warming Newsfeed
DNA India: Scientists have warned about the precarious state of the world's primary forests, as a new study shows that say just 22% of these forests are located in protected areas, equivalent of only 5% of the original ones. Brendan Mackey, Director of the Climate Change Response Program at Griffith University in Queensland, Australia, said that international negotiations are failing to halt the loss of the world's most important primary forests and in the absence of specific policies for primary forest protection...
