Satoshi Nakamoto stands at the end of his sunbaked driveway looking timorous. And annoyed.

He's wearing a rumpled T-shirt, old blue jeans and white gym socks, without shoes, like he has left the house in a hurry. His hair is unkempt, and he has the thousand-mile stare of someone who has gone weeks without sleep.

He stands not with defiance, but with the slackness of a person who has waged battle for a long time and now faces a grave loss...

The Dalai Lama arrived in Santa Fe on April 1, 1991. I was by his side every day from 6 a.m. until late in the evening. Traveling with him was an adventure. He was cheerful and full of enthusiasm—making quips, laughing, asking questions, rubbing his shaved head, and joking about his bad English. He did in fact stop and talk to anyone, no matter how many people were trying to rush him to his next appointment. When he spoke to you, it was as if he shut out the rest of the world to focus his entire sympathy, attention, care, and interest on you...

He heard about the drug trial from a friend in Switzerland and decided it was worth volunteering, even if it meant long, painful train journeys from his native Austria and the real possibility of a mental meltdown. He didn’t have much time, after all, and traditional medicine had done nothing to relieve his degenerative spine condition.

“I’d never taken the drug before, so I was feeling — well, I think the proper word for it, in English, is dread,” said Peter, 50, an Austrian social worker...

There are currently roughly 33,700 U.S. troops in Afghanistan, down from a peak of more than 100,000 in the spring of 2011. Those who have been wounded here have had a better chance at survival than in any previous U.S. war — a result of stunning achievements in battlefield care...

Robert Duncan moved from Los Angeles to Northern California in 2010 to manage marijuana growing operations for a collective of medical marijuana dispensaries. Although California voters legalized medical cannabis more than 17 years ago, the plant remains illegal under federal law, and the Obama administration launched a renewed crackdown on marijuana in California in 2011. That October, Duncan’s grow house was raided. A few months later, U.S. Attorney Benjamin Wagner indicted him and others involved in the dispensary business on the grounds that it had grown too large. Despite California’s struggle with prison overcrowding, and despite new federal guidelines that say size should no longer be considered in prosecution decisions, Duncan, 31, was sentenced to two years in prison. He is scheduled to report to Mendota Federal Correctional Institution near Fresno, Calif., on Monday afternoon. HuffPost Live will go with him.
