Oh, dear.

First off, this lizard? It's not really a lizard. It's an almost vanished species, a reptile like no other.

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.

NOAA: Around World, September Tied Record For Warmest Temperatures

The redder the shading, the further above average were the temperatures in September.

This chart offers another perspective on just how warm it was around the world last month, the National Oceanic and Atmospheric Administration says.

The agency has been keeping records since 1880 and the "average combined global land and ocean surface temperature for September 2012 tied with 2005 as the warmest September on record."

Dot

This is the moon as Morse code.

Beautiful, yes, but not right. The moon isn't a dot. It's too elegant, too pale, too ghostly to be a bit of "information." It's got moods, changes, and on certain nights it's got a man on it, with eyes and a mouth, and yet some people treat the moon as if it's something you can write on.

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 previous elections, candidates from both parties have campaigned on pledges to be environmental presidents. This time, neither candidate is talking much about cleaning up the air or protecting scenic lands.

Instead, the debate has focused on whether and how much environmental regulations hurt businesses, especially the energy industry.

Mostly it's been GOP candidate Mitt Romney criticizing President Obama for what he sees as overzealous environmental regulations that strangle the economic recovery.

Weekend Special: When Cities, People and Highways Glow Like Stars

Justin Wilkinson NASA via TheChive

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.
