Venezuelan President Hugo Chavez is questioning the rash of cancer cases among Latin American leaders and asking if somehow the U.S. might have a way to induce the illness.

With it, your Facebook profile offers highlights from your past, not just your recent happenings. Last week, I urged all of you to carefully curate your Timelines to avoid coming across as vain or revealing forgotten skeletons.

This tiny village of 37 gray homes and farm buildings clustered along the main road in a wind-swept corner of rural eastern Germany seems an unlikely place for a revolution.

Yet environmentalists, experts and politicians from El Salvador to Japan to South Africa have flocked here in the past year to learn how Feldheim, a village of just 145 people, is already putting into practice Germany's vision of a future powered entirely by renewable energy.

In the interview, Steve Wozniak and the late Steve Jobs recall a seminal moment in Silicon Valley history — how they named their upstart computer company some 35 years ago.

"I remember driving down Highway 85," Wozniak says. "We're on the freeway, and Steve mentions, 'I've got a name: Apple Computer.' We kept thinking of other alternatives to that name, and we couldn't think of anything better."
