Robot Pill That Crawls Through Your Intestines
The BBC is reporting on a wirelessly controlled “spider pill” being developed somewhere in Italy. The device supposedly has eight legs and reportedly can crawl through intestines. With an attached video camera, the device might actually become a diagnostic modality for imaging the intestinal tract. The big question is whether it is more unpleasant to have a colonoscope defile you or a robotic gerbil crawl through the insides.

Even though we intuitively think that a particular color looks the same to different people, researchers from The University of Chicago and Vanderbilt University have uncovered that the brain plays a critical role in color perception. The brain actually assigns colors to objects and with a bit of tinkering one can fool the brain to assign the wrong color to an object being viewed. 
We have known for many years that melittin, an ingredient in bee venom, is a poison to tumor cells. Development of therapeutic uses of the substance has been stymied by the fact that melittin does damage to healthy cells as well. Now researchers from Washington University in St. Louis have developed nanoparticles called “nanobees” that can ferry the melittin directly to tumor cells with great specificity.
Next Monday, the Nobel Foundation will announce the winner(s) of this year’s Nobel Prize in Physiology or Medicine. In the following two days, two more Nobels will be revealed: in Physics and in Chemistry. Because of the success of last year’s inaugural Guess-A-Nobel Contest, we decided we’ll repeat this event annually until there is no more science worthy of the prize. This year we’re giving out three
