Social media experts Baratunde Thurston, former digital director at The Onion and author of the book How to Be Black, and Deanna Zandt, author of Share This: How You Will Change the World with Social Networking, answer questions about how to behave in the digital age. This week's topic: leaving a voicemail message in a world that relies increasingly on text-based communication.
I was out of the house, as it happens, for most of the first half of yesterday's Louisville-Duke game, and when I got home and looked at Twitter, before I turned on the TV, there was a huge stack of stuff to read, and the first thing that caught my attention about the game was this.
You sit down, turn on the computer, up comes an image, could be anything, a cloud, a koala bear, a video. On the right side of the screen there are more images like it, or almost like it, so you click on one of those, just because ... because what? Because it's there? Because it's waiting? Because, for no conceivable reason, you suddenly have a yearning for balloon pictures? You don't plan this, you have no plan, but you keep going, gently pulled by the lure of "next."
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.
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.

With a combination of genetic tricks and fancy proteins, researchers have colorfully labelled hundreds of individual neurons with distinctive hues to create a "Brainbow."
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."
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.
