Robotic Anal Probe Navigates Your Colon, Looks For Polyps

We've reported before on robots that play music for you. We've written up reports on robots that memorize your voice commands and can change the channel or lower the volume automatically on your home theater system. And now, we've found a robot that researchers say will navigate its way through your colon, looking for polyps -- a replacement of the dreaded colonoscopy, an uncomfortable procedure that nonetheless can save lives by detecting cancer early.

Yes, we've written about the robot invasion, but never before about one so... invasive.

This new device, which is only in the prototype phase, is being tested now on "snippets of pig colon" to gauge its ability to move itself and navigate through the digestive tract by using small sticky pads called mucoadhesives.

By replacing the need for uncomfortable and painful procedures with endoscopes, Dutch researchers hope more people will decide to have screenings. Early detection of colon cancer is the number way to beat the disease. Colon cancer is the third most diagnosed cancer in the United States and is the second most cause of cancer deaths, according to reports.

The self-propelled robot would not only accomplish its task with less discomfort for the patient, but would also be less likely to damage the colon. While a colonoscopy with an endoscope is relatively safe, about 1 in 500 procedures do result in some damage to the colon.

The mucoadhesives work by allowing the robotic device to grip and release the colon walls without causing damage. And since the colon is constantly producing more mucus, the pads would be essentially washed away within a few hours of the procedure's conclusion.

Intel Developing New Chip for Sub-$250 Computers

When Intel typically develops and debuts a new microprocessor to the computer buying public, it usually gets fanfare around new high speeds attained -- and, of course, the higher price point. The Santa Clara, Calif.-based company may be bucking its own trend the next time around, however, as it finishes development of a new low-priced, smaller-sized chip code named "Diamondville."

IntelThis new chip, the result of advances in smaller "wafer"-making capabilities, is geared for low-cost notebook computers. We're talking less than $250 each.

While the new chip won't break speed records, it will make it possible for computer makers to develop new notebook and desktop PCs that serve basic, everyday functions, such as e-mailing, scheduling and organizing. (Can you think of a few family members who would benefit from such an accessible, inexpensive device?)

Intel expects big-name PC makers to get in on the action once the new chip -- the official brand-name is yet to be decided -- is available.

We've already seen that you can get some great laptops for under $500, but it looks like we can expect more computing options at better price points in the not too distant future.

World's Tiniest Computers


In the world of computing, small is in. Be they laptops or desktops, PCs keep getting smaller. And that's not a bad thing. Smaller means a laptop is easier to toss in a backpack without feeling like you're carrying a computer, or that a desktop can be moved to the living room without looking too tacky. Bottom line: Smaller PCs can be hidden completely from view.

We took a walk around CES collecting shots of the tiniest PCs we could find. Including some that make the Mac Mini look downright bulky.

World's Smallest Digicam Is the Size of a Pin-Head



Digital cameras just keep getting smaller -- so small, in fact, that a camera based on a newly-christened "worlds' smallest" 1.4-millimeter (1/18 of an inch) chip from TDC would be almost completely unnoticeable no matter where you put it. The camera could fit in a package the size of this square:

The chip is ultra-low power, which means it requires only 3.3 volts of electricity. It is also ultra low-resolution, maxing out at 328x250, but that should be plenty high for the surveillance and spying that a camera of this size is obviously designed for.

Above, you can see the OV6920 from TDC compared with a match-head.
