Y'know, I think this bummed-out superhero thing is catching. Depressed Bat-guy, brooding Spider-dude, even the Man of Steel seems existentially troubled in previews of his most recent incarnation.
And smart-alecky Iron Man? He'd appeared inoculated by Tony Stark's reflexive snark from succumbing to a similar ailment — but even he's having anxiety attacks these days. Ever since that Avengers dust-up with those unpleasant aliens last summer, he's evidently been having trouble sleeping.
Natalie Maines is a small woman with a really big voice. Flanked by Emily Robison on banjo and Martie McGuire on fiddle, Maines powered the Dixie Chicks to some 30 million records sold. And then came the collapse — after what the band calls "the incident."

An insect's eye lets it see really well because each of its light-sensitive cells has a dedicated lens. This miniature camera, which mimics an insect eye, is made from an array of microlenses arranged on a stretchable sheet that can be inflated like a balloon to a hemispherical shape.
A smartphone can tell you where to get a cup of coffee, but it can't go get the coffee for you. Engineers would like to build little machines that can do stuff. They would be useful for a lot more than coffee, if we could figure out how to make them work.
But the rules of mechanics change at small scales. Friction becomes dominant; turbulence can upend a small airplane.

Employers using the E-Verify program are required to post an E-Verify Participation Poster, shown here in a handout photo. A Senate bill would make participation in the system, used to check employees' immigration status, mandatory for all employers.
Some employers around the nation have been using E-Verify to check the immigration status of employees for years. Operated by the Department of Homeland Security, the online system is designed to make it harder to hire unauthorized workers — and harder for those workers to find jobs.
While participation in the program has been voluntary since 1996, the immigration bill now in the Senate would make E-Verify mandatory.
