Stories about: Defense Advanced Research Projects Agency

Think of supercomputers and you tend to think of multi-million dollar machines that easily take up a football field. With miles and miles of cabling and cooling systems running beneath the floors.

University researchers have developed a high-resolution microscope that is small enough to sit on a computer chip.

Artificial intelligence promised us great technology. But has it delivered?

Intel and Cray have launched a joint effort to develop new multi-core technologies as part of an effort to build multi-petascale systems.

Linux visionary Hans Reiser has been convicted of first-degree murder for killing his estranged wife in 2006 and faces life imprisonment.

When it comes to computing technology, the research goal of the Defense Advanced Research Projects Agency can be summed up in two words: power and speed.

In an attempt to improve computer performance, Sun Microsystems is working on technology to let chips communicate using lasers instead of electricity, in what would be a break from conventional computer design.

In the 19th century, British mathematician Charles Babbage invented the "difference engine," a mechanical computer that had an enormously complex arrangement of levers, ratchets and gears. Had this prototypical chunk of steampunk machinery ever been completely built, it would have weighed several tons.

Supercomputers may soon be the same size as a laptop if IBM brings to market research detailed on Thursday, in which pulses of light replace electricity to make data transfer between processor cores on a chip up to one-hundred times faster.

Creative scientists have until next week to submit proposals for creating a shape-shifting military robot that can shrink and then reconfigure itself to normal height and shape.

IBM researchers have showed a prototype optical transceiver chipset which they claim will allow people to download movies or share online data eight times faster than current technology allows.
