St. Louis Zoo builds love hotel for salamanders

Ozark hellbenders, aka "snot otters" and "lasagna sides," are among the world's largest and least cute salamanders. Looking at them, it’s probably not a big surprise that they’re having a hard time breeding -- although inexplicably, scientists think it’s NOT because of their pancake heads or beady little eyes, but some problem in the natural environment. Now that there are fewer than 600 hellbenders left in Ozark rivers, scientists at the Saint Louis Zoo decided to step in and create a place for the salamanders to get it on.

The salamanders' love nest is a simulated river built to bring out amorous feelings in hideous beasties:

The zoo has built a kind of honeymoon resort for salamanders, assembling a mini water treatment plant and carefully tweaking water chemistry to recreate their cold, fast-flowing Ozark streams — minus any distracting predators or pollution. ...

Critical List: Toxic chemicals on the rise; baby seals in trouble

The EPA may retest water in Dimock, Pa., where residents have linked polluted water to fracking operations. In its first round of testing the town's water, the EPA declared it safe.

GM is fixing up the Volt in order to avoid in real-life battery fires like the ones that started during testing.

As winter sea ice disappears in the Arctic, fewer baby harp seals are making it.

The amount of toxic chemicals shunted into the environment went up 16 percent between 2009 and 2010, according a new EPA report.

Wildfires too hot? Jump in the Senate office pool

Each year, congressional staffers participate in a macabre annual office pool in which they try to predict how many acres of U.S. land will burn in wildfires. And thanks to climate change, it starts earlier every year.

Embattled teen genius actually better, smarter than most people

Back in August, the Internet discovered Aidan Dwyer, a 13-year-old go-getter who worked out a way to make solar panels more efficient. Because nobody likes a 13-year-old go getter, the Internet basically told him NO YOU'RE WRONG.

Okay, so he should have measured power instead of voltage when testing his solar panel design. But it turns out Dwyer is totally getting the last laugh here, and is proving that nerdy 13-year-old go-getters actually are just better at life than most people on the Internet. Dwyer's spoken at PopTech's annual innovation conference and is scheduled to speak at the World Future Energy Summit.
