If you live in Missouri, they've already gone.

But back East, cicadas are about to climb out of their little holes in the ground, wriggle out of their skins, like this ...

... so after 17 years of getting ready, they can now do the thing they hope, hope, hope to do — which is, if at all possible, make a baby.

Trapped By The Web — But For How Long? Take the Kelberman Challenge

I'm Google Dina Kilberman

You sit down, turn on the computer, up comes an image, could be anything, a cloud, a koala bear, a video.

The U.S. Environmental Protection Agency could soon issue a final ruling that aims to force oil companies to replace E10, gasoline mixed with 10 percent ethanol, with E15.

This move could come just as widespread support for ethanol, which is made from corn, appears to be eroding.

Mike Mitchell was once a true believer in ethanol as a homegrown solution to foreign oil imports. He owns gas stations, and he went further than most, installing expensive blender pumps that let customers choose E15, E20 and all the way up to E85.

So is refusing to apologize for those errors.

From toddlers and talk show hosts to preteens and presidents, we all know people who have done stupid, silly and evil things, then squared their jaws and told the world they've done nothing wrong.

Somewhere Over The Brainbow: The Journey To Map the Human Brain

Originally published on Sun March 31, 2013 9:55 pm

More than 100 years ago, Golgi staining on nerve cells opened the gates to modern neuroscience. Scientists recently developed the Technicolor version of Golgi staining, Brainbow, allowing more detailed reconstructions of brain circuits.

During the State of the Union, President Obama said the nation is about to embark on an ambitious project: to examine the human brain and create a road map to the trillions of connections that make it work.

"Every dollar we invested to map the human genome returned $140 to our economy — every dollar," the president said. "Today, our scientists are mapping the human brain to unlock the answers to Alzheimer's."

Originally published on Fri March 29, 2013 7:55 pm

Transcript

AUDIE CORNISH, HOST:

Tucked away inside the new federal budget for this year - which President Obama signed yesterday - is one, small paragraph dealing with genetically engineered crops. That paragraph - actually, one long, complicated sentence - has the biotech industry smiling. But opponents of biotech crops are hopping mad. They say this biotech rider, as they call it, is a blatant attempt to shield biotech crops from all judicial oversight.

Joining me now to talk about this is NPR's Dan Charles. Welcome, Dan.
