The artificial organ was accurate nearly 82 percent of the time, said its creators -- and could be the first step towards developing robots with a sense of taste.

Facebook shares jumped to record highs Thursday, buoyed by news of stronger-than-expected profits and sizzling gains in mobile advertising revenue.

Apple reshaped technology and society when Steve Jobs unveiled the iPhone seven years ago. Now, the trend-setting company is losing ground to rivals that offer what Apple has stubbornly refused to make: smartphones with lower prices and larger screens than the iPhone.

Like any ordinary printer, this machine ingests a blank page and spits it out covered in print.

Documents leaked by former NSA contactor Edward Snowden suggest that spy agencies have a powerful ally in Angry Birds and a host of other apps installed on smartphones across the globe.

The documents, published Monday by The New York Times, the Guardian, and ProPublica, suggest that the mapping, gaming, and social networking apps which are a common feature of the world's estimated 1 billion smartphones can feed America's National Security Agency and Britain's GCHQ with huge amounts of personal data, including location information and details such as political affiliation or sexual orientation.
