Take air. Suck out CO2. Make fuel. A lab advance hints at a future for artificial photosynthesis

Researchers believe that artificial photosynthesis that sucks excess CO2 out of the air could one day help fight climate change. But capturing the gas is only half the challenge. The other half is what to do with it once you've got it. Lauren Sommer reports on a potentially breakthrough technology that uses artificial photsynthesis to turn CO2 from the air into industrial chemicals and natural gas.

Water supply in the west isn't only about rain, or the lack thereof. A good deal of water scarcity issues have to do with decades-old policy and entrenched infrastructure. It’s a convoluted situation, and a team of reporters are working to make sense and put broader perspective on the western water crisis and the central role of the Colorado River.
