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.
Acne, the scourge of many an adolescent life, is getting harder to treat, but 80 percent of teenagers have some form of it.
Conventional treatment includes topical and oral antibiotics. Studies are now finding the bacteria that cause acne are increasingly resistant to antibiotic treatment. Alternatively, there are effective laser treatments. But these are costly and typically not covered by insurance.
In this video, we are flying over the Earth, looking down and seeing what astronauts see when it's nighttime, when lightning storms flash like June bugs, when cities look like galaxies, when you can see where people are. It's quietly astonishing.
This montage of space footage was assembled and narrated by NASA scientist Justin Wilkinson. There's another one, which takes us around the Earth in daytime.
"I grew up wanting to fly," says Graham Bowen-Davies. "I guess I just settled for being an engineer."
He's standing on an indoor track in southern Maryland, watching a giant helicopter take flight. At the end of each of its four spindly arms — arms he helped design and build — a giant rotor churns the air. In the cockpit sits the engine: a 0.7-horsepower, 135-pound graduate student named Kyle Gluesenkamp.
Gluesenkamp is pedaling like crazy to keep the rotors spinning and the craft aloft.

In 1894 Octave Chanute published a volume called "Progress In Flying." A more appropriate title would have been "Lack Of Progress In Flying." The book's detailed list of failed flying machines – from Da Vinci's famous flapping ornithopter to the fins an overconfident French nobleman strapped to his arms and legs – is very humorous. The book's detailed list of injuries suffered by would-be aviators is not.

And I'm Robert Siegel. They're calling it Mission 26. After 25 trips in orbit, Space Shuttle Endeavour is making its final journey, this one through the streets of Los Angeles. For the next two days, the shuttle will be towed from Los Angeles International Airport to the California Science Center in downtown L.A. where it will become a museum piece. NPR's Carrie Kahn caught up with Endeavour along its route today.
And now to one more rare thing that came from space: a meteorite. Some of the most unusual and prized meteorites fell to Earth from Mars. In a new journal article, scientists describe the latest one that was discovered, and this weekend, you can buy a piece of it. NPR's Christopher Joyce has this story of a journey from Mars to a Manhattan auction house.
CHRISTOPHER JOYCE, BYLINE: The meteorite is called Tissint, and it contains a unique story about Mars.
For nearly a decade, scientists and Northwest tribes in Washington state fought bitterly over whether to bury or study the 9,500-year-old bones known as Kennewick Man. Scientists won the battle, and now, after years of careful examination, they're releasing some of their findings.
For starters, Kennewick Man was buff. I mean, really beefcake. So says Doug Owsley, head of physical anthropology at the Smithsonian's National Museum of Natural History, and the man who led the study of the ancient remains.
Curiosity scooped its first sample of Martian soil on Oct. 7, but activities were halted after a small, bright object — which NASA now says is likely a piece of plastic from the rover — was spotted on the ground. Mike Watkins, Curiosity's mission manager, provides an update.
