Three years ago, venture capitalists were pouring billions of dollars into technologies like solar power, wind power, biofuels and fuel cells. The federal government followed, directing some $44.5 billion into clean technology from late 2009 to late 2011 through loans, subsidies and tax incentives.
But now the clean-tech industry is facing leaner times, in part because of cheaper natural gas prices, the effects of the financial crisis and China's growing solar industry.

Koko the gorilla is world-famous for her ability to communicate with humans using phrases in American Sign Language, and for her gentle play with pet cats. Now, a new study on Koko's play with wind instruments shows that she skillfully controls how she breathes.
That's a knockout conclusion because scientists have thought that humans alone, out of all the primates, can gain skillful, voluntary control over the act of breathing.
