Microsoft unveiled its new Xbox One Tuesday, displaying a device that takes new steps in game consoles' journey to becoming all-purpose entertainment and communication devices. The new console replaces the Xbox 360, which has been on the market for nearly eight years.

Artifacts that once belonged to Mohandas K. Gandhi, the Indian independence leader who took a vow of poverty, could fetch hundreds of thousands of dollars at auction.

A federal appeals court ruled Tuesday in favor of the government's decision to keep photos and video of the May 2011 raid that killed Osama bin Laden a secret, rebuffing a conservative watchdog group that had sought their release.
