As with tropical trees around the world, the koa forests of Hawaii have been decimated — cut down to make way for sugar plantations and cattle ranches. One company is using an innovative business model to bring back koa forests. The secret is a digital tag that helps track individual trees.

At upscale Hawaiian shopping malls like Kings' Shops, wood from the native koa tree is in high demand. Its color ranges from light to dark brown. Koa's curving lines make it popular for furniture, or ukuleles.

The drought across much of the Western U.S. is now in its fourth year. In California — where it's the most intense — farms are not under the same strict orders to conserve as cities are.

And inside the agriculture industry, farmers are quietly debating how best to respond to the drought. Given uncertainty around pending state regulations, some say there may be an incentive to not invest in water-saving technologies right now.

The Great 'Beyond': Contemplating Life, Sex And Elevators In Space

Astronomer Chris Impey examines the possibilities of the universe in his new book Beyond. "I like the idea that the universe — the boundless possibility of 20 billion habitable worlds — has led to things that we can barely imagine," he says. In the 1970s, NASA Ames conducted several space colony studies, commissioning renderings of the giant spacecraft which could house entire cities.

The possibility of humans colonizing outer space may seem like the stuff of science fiction, but British astronomer Chris Impey says that if the U.S. were pumping more money into the space program, the sci-fi fantasy would be well on its way to reality.

Here's a job that sounds perfect for either a superhero or a glutton for punishment: Get nearly 200 countries to finally agree to take serious action on climate change.

Two men have taken on this challenge. They're leading some international negotiations that will wrap up later this year in Paris at a major United Nations conference on climate change.

It's been more than 20 years since Jurassic Park came out, and scientists have been cloning animals almost as long.

So where are the baby velociraptors already?

In Russia, there is a park all ready for woolly mammoths and scientists there say it's just a matter of time before they can bring back actual mammoths to enjoy it. But why bring back a species that went extinct thousands of years ago?

A new glimpse of what the universe looked like in its youth has been captured, thanks to researchers who determined that light from the galaxy known as EGS-zs8-1 has spent more than 13 billion years traveling to reach us here on Earth.

The blue galaxy, which was named for its coloration after its initial discovery by the Hubble telescope, was studied by a team of astronomers based at Yale University and the University of California, Santa Cruz.
