U.S. Defense Secretary Chuck Hagel got a first-hand look at a life-size robot Tuesday that resembles Hollywood's "Terminator," the latest experiment by the Pentagon's hi-tech researchers.

But unlike the cinematic version, the hulking Atlas robot is designed not as a warrior but as a humanitarian machine that would rescue victims in the rubble of a natural disaster, officials said. 

Brazil's Congress on Tuesday passed comprehensive legislation on Internet privacy in what some have likened to a web-user's bill of rights, after stunning revelations its own president was targeted by U.S. cyber-snooping.

The lower House of Deputies had passed the bill earlier, and late Tuesday the Senate gave it a green light. That leaves only the expected signature into law from President Dilma Rousseff.

AT&T says it will expand super-fast Internet services to as many as 100 additional U.S. cities in 25 metropolitan areas.

Hidden in the Twittersphere are nuggets of information that could prove useful to crime fighters -- even before a crime has been committed.

The career-focused social network LinkedIn announced Friday it has 300 million members, with more than half the total outside the United States.
