MIT's RealNose Project Makes Artificial Nose Breakthrough

The quest for the ultimate artificial nose is still underway, and thanks to a major breakthrough by the folks over at MIT, it might be sooner than later that we're all unwrapping stylish sniffers under the Christmas tree. More importantly, the fruits of MIT's RealNose project could replace drug and explosive-sniffing dogs as well as detect certain medical conditions via the odors emitted.

Up to now, the tricky part of studying the sense of smell has been in isolating proteins (olfactory receptors) to get a good look at how they work. But in this latest development, researchers are now able to produce specific receptors using wheat germ, through a process referred to as PNAS. Engineered mammalian cells can be used to the same effect. What makes this so great is, while the human nose is relatively limited in what it can detect, this discovery could unlock the potential to detect an almost infinite range of odors. G.I. Joe with "action nose" here we come. [Via PhysOrg]

MIT's EMF Bracelet Detects Radiation Poisoning


We've seen our fair share of EMF detectors and other tin foil hat apparel, but no endeavor is complete without the MIT stamp of approval. Cati Vaucelle's EMF sensor bracelet is designed to pick up on any potentially harmful electromagnetic fields, allowing you to dance around the veritable minefield of computers and cell phones in your workplace, unscathed by the -- maybe, maybe not -- lethal effects of radiation being emitted.

Nevermind about looking like a freak -- better safe than sorry, right? The bracelet, sensitive up to 14-inches, features an integrated LED that's illuminated whenever an EMF field over 50kHz is detected. If you'd like to see this prototype in action, check it out here after the break.
