Intel Silicon Photonics Chip Is World's Fastest (and Prettiest) [Intel]
MIT's Tech Review has the scoop that Intel's wizards have come upwith a new chip entirely made out of silicon that "can encode 200 gigabits of data per second on a beam of light" versus the measly 100 Gbps that the fastest optical networks currently churn at—which aren't made of silicon. Which mea
Pentax P80 Is Less Than an Inch Thick, but Has 12 Megapixels, Rapid Face Detection and 720p Video Recording
Pentax's P80 camera doesn't really do anything that original or spectacular for its time—the 12.1 megapixel sensor, 720p, 30 fps video recording, face detection and 0.8-inch thickness are all pedestrian compared to other cams—BUT it is $200. The P80 can even detect faces at an angle and
Coming Soon: Mind-Reading Cell Phones
What if cellphones knew what sort of moods we were in? What if they could anticipate to whom we'd crave to talk? What if they knew which calls we're waiting for? If Intel has its way, they soon will. The cell phones of 10 years ago look like ancient relics compared to the smartphones of today. Bu
Why More Megapixels Isn't Always More Better
Between all the new digital cameras pooped out before the upcoming PMA show and the crazy cameras buried inside cellphones at MWC, it's a good time to go over why more megapixels isn't necessarily better. So, the nutshell explanation of how a digital camera works is that light lands on a sens

Powershot SD780 Is the Puny Point-and-Shoot Canon Employees Wanna Take Home
Canon's got a bajillion cameras laying around, but this little guy, the Power SD780, is the one that most of the Canon reps said they want to stick in their pants and take home. That's because it's really teeny and the easiest to stick in your pants, and it pulls off the square form factor really n![Physicists Devise Warp Drive Plans for Traveling Faster Than Light [Science]](http://gizmodo.com/assets/resources/2008/08/eventhorizon.png)
Physicists Devise Warp Drive Plans for Traveling Faster Than Light [Science]
Warp drives, those vague constants of science fiction movies, might actually become real, allowing for travel faster than the speed of light. According to two physicists from Baylor, they've come up with a concept for a warp drive that would shrink space, allowing for a craft to jump ahead vast distIBM Roadrunner Tops Cray as the Official World’s Fastest Supercomputer

It’s like a geek soap opera. Just last week, Cray bragged that their updated Jaguar XT supercomputer was the world’s fastest. Now this week, IBM responds to the trash talk with a number one ranking of their Roadrunner system on the newly published Top500 supercomputing list.
Both the IBM and Cray systems break the petaflop processing barrier according to Top500 measurements (1.45 petaflops vs 1.38 petaflops, respectively). Heck, even IBM admitted to us that the two computers “run neck and neck.” But there’s a huge difference between them.
The Roadrunner uses roughly half the power of the Jaguar XT.
It assembles 12,960 IBM PowerXCell 8i Cell Broadband Engine processors and an additional 6,948 AMD Opteron Dual-Core processors. The AMD equipment handles “basic” functions while the IBM chips handle the intense number crunching. (Read all about the Roadrunner here.)
Seeing as the Cray XT5 uses 45,000 quad-core AMD Opteron processors to get the same job done, you’ve gotta be at least a little impressed. [Top500]
