The only remaining laboratory of one of the greatest American inventors may soon be purchased so that it can be turned into a museum, thanks to an Internet campaign that raised nearly a million dollars in about a week.

The lab was called Wardenclyffe, and it was built by Nikola Tesla, a wizard of electrical engineering whose power systems lit up the Chicago World's Fair in 1893 and harnessed the mighty Niagara Falls.

As the Earth's average temperature creeps upward, climate scientists have predicted record heat waves and droughts. That's what we've seen this summer in the U.S.

The question has become, are we now seeing the real damage climate change can do?

Mitt Romney outlined an energy plan Thursday that would guide his Republican presidency. It focuses heavily on expanding the supply of fossil fuels. The presumptive nominee said the U.S., Mexico and Canada together could reach energy independence by 2020.

But the plan makes no mention of climate change and would end subsidies for cleaner sources of energy, such as wind and solar.

Fire scientists are calling it "the new normal": a time of fires so big and hot that no one can remember anything like it.

One of the scientists who coined that term is Craig Allen. I drive with him to New Mexico's Bandelier National Monument, where he works for the U.S. Geological Survey. We take a dirt road up into the Jemez Mountains, into a landscape of black poles as far as you can see.

Federal regulators and fast-food companies reacted with unprecedented speed this week to the release of an undercover video that animal-rights activists shot inside a California slaughterhouse. The video — which, we'll warn you, is pretty graphic — shows employees of Central Valley Meat Co. using electric prods repeatedly on cattle that appeared unable to get to their feet.

I've written before in this space about how an animal obituary may help mark a life of significance. Here is my obituary for Ivan the gorilla.

Intense forest fires have been raging across the western United States this summer. So far this year, nearly 43,000 wildfires have torched almost 7 million acres of land.

As NPR Science correspondent Christopher Joyce and photographer David Gilkey report from Arizona and New Mexico this week, the forests of the American Southwest have become so overgrown that they're essentially tinderboxes just waiting for a spark.

You may not be familiar with the name Roger Angel, but if there were ever a scientist with a creative streak a mile wide, it would be he.

Angel is an astronomer. He's famous for developing an entirely new way of making really large, incredibly precise telescope mirrors. But his creativity doesn't stop there. He's now turned his attention to solar power, hoping to use the tricks he learned from capturing distant light from stars to do a more cost-efficient job of capturing light from the Sun.

The history of fire in the American Southwest is buried in a catacomb of rooms under the bleachers of the football stadium at the University of Arizona.

Here rules professor Thomas Swetnam, tree ring expert. You want to read a tree ring? You go to Tom. He's a big, burly guy with a beard and a true love for trees.
