Twitter took some heat earlier this month for resetting more passwords than necessary after detecting a security breach in its microblogging network, as CNET's Daniel Terdiman reported on the Internet & Media blog.

CNET News Editor Steven Musil describes the two attacks on the Reuters Twitter account last August, and Fox News' infamous erroneous … Read more

Tetrapod is a quadruped designed to withstand high levels of radiation, but it couldn't seem to take the glare of cameras.

It's designed to survey the plant's highly radioactive buildings and debris, and can apparently withstand a 100 millisievert environment for a year. … Read more

When it comes to detecting a wide range of extremely faint scents, including the primary vapor that emanates from TNT-based explosives, dogs are the gold standard. But researchers out of the University of California at Santa Barbara, report in the journal Analytical Chemistry that they just may have man's best friend beat -- in the form of a fingerprint-sized silicon microchip.

"Like a person, a dog can have a good day or a bad day, get tired or distracted," Carl Meinhart, a mechanical engineering professor who led the research, said in a school news release. "We … Read more

Norton Mobile Security has taken the unusual step today of merging its mobile licensing so that you pay once and can use the mobile security suite on either Android or iOS. It's an effort to make Norton's security more accessible, and parent company Symantec wants to turn Norton accessibility into a security service.
