It's a diagnosis nobody in grad school would ever expect. Arjit Guha, who's working on a doctorate on sustainability at Arizona State, felt sick after coming back from a trip to India in early 2011.

The Washington Post's Sarah Kliff told the story of how Guha has raised money for his care. The centerpiece is a website — Poop Strong — that is a takeoff on Lance Armstrong's LiveStrong cancer project. Guha has harnessed the Web to sell T-shirts and tote bags and to raffle off items donated by celebrities.
