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.

And I'm Robert Siegel. Today, the Environmental Protection Agency proposed a new rule to clean up gasoline. The regulation would reduce ozone and other air pollutants by close to 30 percent. That would benefit 100 million people who now live in areas that at times have unhealthful air. NPR's Richard Harris reports.
A large new government study should reassure parents who are afraid that kids are getting autism because they receive too many vaccines too early in life.
The study, by researchers at the Center for Disease Control and Prevention, found no connection between the number of vaccines a child received and his or her risk of autism spectrum disorder. It also found that even though kids are getting more vaccines these days, those vaccines contain many fewer of the substances that provoke an immune response.
