Given Citigroup's stated plans, a massive headcount reduction announced is sure to include a fair share of IT jobs.

Someday, you might take business data off a disk drive and move it into the nucleus of an atom.

Researchers at McGill University in Montreal have discovered a new state of matter that they say could greatly extend Moore's Law.

The hugely promising security technology of Quantum Key Distribution (QKD) has moved an important step closer to commercialization with the announcement by UK-based researchers that they can now shift encryption keys around at speeds of 1Mbps.

Warning: Your keyboard could be a danger to you and the environment.

Security software customers are speaking with their feet: They want security updates and other security interruptions out of their faces, and they won't hesitate to dump their security suites because of performance drag -- whether or not it's actually the security software that's to blame.
