Intel has developed a prototype interconnect that uses light to transmit data inside computers at up to 50 gigabits per second. The optical technology could ultimately replace copper wires to carry data inside or around computers. An entire high-definition movie can be transmitted each second with the prototype, the researchers said. The technology will also be able to carry data over longer distances than copper wires, Intel said.

AT&T says it won't interfere with a highly anticipated talk on intercepting cell phone calls at the Black Hat conference this week, even though rumors are circulating that it will do just that. Last week, hacker Chris Paget said he plans to demonstrate how to set up what's essentially a fake cell tower that lets him listen in on nearby mobile calls. His talk is scheduled for Saturday. On Tuesday, though, he wrote on his blog that he had heard that AT&T may be considering suing him to stop his talk.

Twitter has been having trouble with a digital certificate that secures communications to its Web site. Users posting or reading messages with third-party apps such as Tweetdeck are reporting error messages saying that an SSL certificate issued by Equifax to "*.twitter.com" has expired or is invalid. The messages indicated that the certificate used for the server api.twitter.com expired on Monday, although other users saw a message Monday saying that the certificate had been renewed on July 13.

Yahoo Japan's decision to replace Microsoft with Google as its main search partner has met with protest from Microsoft, which called the deal "anticompetitive." But the company declined to say if it will try to challenge the deal on legal grounds. The deal raised eyebrows because Microsoft and Yahoo have a broad search and advertising partnership in the U.S. and many other countries. That deal doesn't extend to Japan, however, where Yahoo owns only 34 percent of Yahoo Japan. The majority is owned by Japan's Softbank.
