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."
The mostly forgotten explorer Paul du Chaillu introduced the world to gorillas. His methods were attacked and his work discredited during his lifetime, but he also experienced fame and redemption.
Author Monte Reel illuminates the little-known tale of the 19th century explorer in his new book Between Man and Beast: An Unlikely Explorer, the Evolution Debates, and the African Adventure That Took the Victorian World by Storm.
Fifty years ago, the notorious Alcatraz prison shut its gate behind guard Jim Albright as he escorted the last inmate off the island on March 21, 1963.
"As we're going out, I know, when I come back from this trip, I don't have a job, I don't have a home anymore," Albright remembers. "I didn't want the island to close, I didn't want to leave. I liked it there."

A group of nuns shares a meal in Beyond the Hills. Though the director is hesitant to underline metaphors in his film, contemporary observers won't find it hard to discover what seems like suggestive references to the Romania of dictator Nicolai Ceaucescu.
Cristian Mungiu became the poster boy for the Romanian New Wave when his film 4 Months, 3 Weeks and 2 Days took the top prize at the Cannes International Film Festival in 2007. Like that film, Mungiu's latest turns an unblinking camera on two troubled young women in a dysfunctional society. Beyond the Hills is now opening in theaters across the U.S.
Like its predecessor, Beyond the Hills was a prizewinner at Cannes: Its two young stars shared the best actress prize last year, and Mungiu won best screenplay.
It is hard to imagine that after three years of acrimony and debate we could still be so confused about President Obama's Affordable Care Act.
Is it actually possible Americans know less about Obamacare now than they did three years ago? Apparently that is the case, and the news comes just as the most sweeping effects of the law are about to kick in.
