Hundreds of Colorado federal lab workers including two Nobel Prize recipients are furloughed during the government shutdown. Other university and contract workers are shut out of federal buildings and labs.
It has been a deadly year for the people who fight wildfires. In total, 32 people have lost their lives fighting fires in 2013; the highest number in nearly 20 years, according to the National Interagency Fire Center.
Just one incident accounts for most of those deaths, the Yarnell Hill fire in Arizona. In June, the blaze blasted through a firefighting crew known as the Granite Mountain Hotshots; 19 of the 20 men died.

You wouldn't be surprised to learn that a laboratory run by the U.S. Department of Commerce is working on more precise methods to measure stuff.
However, you might not expect it to be at the cutting edge of the mind-bending world of quantum physics. But on Tuesday, David Wineland became the fourth employee at the National Institute for Standards and Technology, a federal lab, to win a Nobel since 1997. Wineland learned he will share the Nobel Prize in physics with Frenchman Serge Haroche for work that's both esoteric and practical.
