The UCLA campus was flooded last week after a 30-inch water main broke. The city of Los Angeles is on a 300-year replacement plan for its water system.

Most of us don't really give it a second thought: We turn on the tap, pour a glass of water and drink it down. But the U.S. has experienced a number of water-related problems this year, from the toxic algae bloom on Lake Erie to a massive water main break in Los Angeles that spilled 20 million gallons of water, and a chemical spill into West Virginia's Elk River that fouled the drinking water supply.

By selecting for a slightly different shape in the scales of the wing, scientists bred a population of brown butterflies into blueness.

Explore the soft, smooth-looking surface of a butterfly wing through an electron microscope and you'll see it's actually covered in rugged, textured scales that overlap like shingles on a roof.

Colorado’s Local Control Of Oil And Gas Is A Question Of Degrees

A drill site in Frederick abuts a residential neighborhood, August 2013. The growth of drilling near Front Range population centers has prompted bans and calls for more local control of drilling.
Jim Hill KUNC

When the city of Longmont's fracking ban was struck down by a Boulder judge, it could have been seen as a setback for those seeking to assert local control over surging oil and gas development along Colorado's populous Front Range.

A longer view of the matter, though, shows that local communities all across the state have exerted control over oil and gas within their boundaries for decades.
