Want to know how many explosions and fires there have been at oil and gas operations in Colorado? How many people have died or been injured? It's not easy to find this information because the state doesn't require detailed reporting. But researchers at the Colorado School of Public Health dug deep, and have a new study out. Then, the governor has just signed the first state law dealing with driverless cars. Why lawmakers put only a "light touch" on regulations. And only 17 American artists landed a spot in the Venice Biennale, the prestigious art exhibition that takes place every two years in Italy. One of the 17 is a Colorado Springs sculptor who uses pantyhose -- and other everyday objects -- in her work. This honor comes late in Senga Nengudi's career.
