There's a boom in natural gas production in the United States, a boom so big the market is having trouble absorbing it all.
The unusually warm weather this winter is one reason for the excess, since it reduced the need for people to burn gas to heat their homes. A bigger reason, however, is the huge increase in gas production made possible by new methods of coaxing gas out of shale rock formations.
The U.S. is facing a growing surplus in natural gas. Renee Montagne talks to Amy Myers Jaffe, of the Energy Forum at the Baker Institute at Rice University, about the glut. She expects some consolidation in the industry.
Researchers haven't given much thought to the effect of noise and noise pollution on plants. After all, plants don't have ears — at least, not the kind you hear with — so there doesn't seem to be much point. But thanks to ecologist Clinton Francis, that could be about to change.
Francis is a postdoctoral researcher at the National Evolutionary Synthesis Center in North Carolina. But he has spent the past few years in northwestern New Mexico, studying noise pollution in Rattlesnake Canyon.
