Arctic Ozone at Risk of Loss

Cold temperatures in the upper atmosphere and the lingering presence of ozone-destroying pollutants have set the stage for what could be a record loss in protective ozone over the Arctic.

Global warming and chlorofluorocarbons (CFCs) are likely contributers to what could be a bad spring for the Arctic: "'We have done everything to protect the atmosphere from CFCs, still we get record ozone loses once in a while,' said Markus Rex, an ozone researcher with the Alfred Wegener Institute for Polar and Marine Research in Germany. 'Right now, at the relevant altitude, we have lost about half of the ozone that should be there,' Rex told LiveScience.com.


Rex and other researchers from Europe, Russia and North America came to this conclusion based on data collected by 30 stations in and slightly south of the Arctic."

China’s artificial sun reaches fusion temperature: 100 million degrees

In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.

Surprising Science
  • The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
  • Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
  • Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.

  • During the Vietnam War, Robert McNamara began a program called Project 100,000.
  • The program brought over 300,000 men to Vietnam who failed to meet minimum criteria for military service, both physically and mentally.
  • Project 100,000 recruits were killed in disproportionate numbers and fared worse after their military service than their civilian peers, making the program one of the biggest—and possibly cruelest—mistakes of the Vietnam War.
