Originally published on Thu October 18, 2012 12:11 pm

This Sept. 16 image released by NASA shows the amount of summer sea ice in the Arctic, at center in white, and the 1979 to 2000 average extent for the day shown, with the yellow line. Scientists say sea ice in the Arctic shrank to an all-time low of 1.32 million square miles on Sept. 16, smashing old records for the critical climate indicator.

Adolescent brains have gotten a bad rap, according to neuroscientists.

It's true that teenage brains can be impulsive, scientists reported at the Society for Neuroscience meeting in New Orleans. But adolescent brains are also vulnerable, dynamic and highly responsive to positive feedback, they say.

As the election nears, energy policy remains a regular topic on the campaign trail. Controversial subjects like arctic drilling and hydraulic fracturing continue making headlines as the political class debate our nation's changing energy mix.

Urushiol, the chemical in poison ivy, is also harvested from the Japanese lacquer tree to coat lacquerware. Here, a rash caused by lacquerware that likely was not properly cured.

You'd think that someone who is a science correspondent and is as allergic to poison ivy as I am would have heard of urushiol, but no. I didn't recognize the word when I saw it a week or so ago. Now, thanks to my new beat (Joe's Big Idea), I'm allowed to dig a little deeper into stories, and what I learned about urushiol is pretty amazing.
