One of Australia's top police officers on Monday criticized violent video games that glorify rape and murder, after a spate of high-profile knifings by young people.

South Korea's Samsung Electronics said Friday it would unveil a new mobile device this month, just weeks before the likely debut of the iPhone 5 from arch-rival Apple.

European researchers said Thursday they had developed the world's first real-sized, five-fingered robotic hand able to grasp and manipulate objects with human-like dexterity.
