Canadian scientists scan your brain, know how you want to hold your hand
O Canada -- your wacky scientists are at it again. And this time, the bright minds over at the University of Western Ontario have their third eye set on a certain precognitive prize. Avoiding the messier open-skull, electrode-imbedding alternative, researchers at the Centre for Brain and Mind employed functional magnetic resonance imaging (fMRI) to successfully predict the action of participants' hands before they'd moved a muscle. After a year of brain-scanning trials, scientists learned to accurately foretell which signals were linked to one of three set actions: grabbing the top of an object, its bottom, or simply reaching out to touch it. Like our clairvoyant cousin's previous beverage-predicting breakthrough, the spoils of this study go to prosthetic limb motion control and the paralyzed who'll use it. We know what you're thinking, but we're not going to make the obvious Thing joke here. Instead, we have to wonder -- What Would Ms. Cleo Do? Full release after the break, but you already knew that.
Researchers receive grant to develop color-changing contacts for diabetics
Contact lenses that act as a glucose monitoring system for diabetics aren't exactly a new idea, but it looks like a group of researchers from the University of Western Ontario might be a bit closer to making them a reality, as they've now received a $200,000+ grant from the Canada Foundation for Innovation to further develop the technology. The secret to their contacts are some "extremely small" nanoparticles that are embedded in the hydrogel lenses which, like some similar systems (such as those pictured at right), react to the glucose molecules in tears and cause a chemical reaction that changes the color of the lenses -- thereby informing the wearer when their blood sugar is too low or too high. What's more, the reseachers say the same basic idea could also have a wide range of other applications beyond glucose monitoring -- for instance, being used in food packaging to indicate if the food is spoiled or contaminated.

Man-made 'tethered tornadoes' touted as a viable power source
With all the wacky unconventional proposals we've seen people come up with for generating electricity in an environmentally friendly manner, is it really so outrageous to think that giant, man-made tornadoes could be harnessed to power a small city? Well that's exactly the idea being floated around the University of Western Ontario these days, which is currently testing a scale model of retired refinery engineer Louis Michaud's patented vortex engine -- a machine fueled by excess power plant heat that uses the physics of convection inherent in rising air to drive electricity-producing turbines. In its most grandiose realization, the engine (inventor's rendition pictured above) would be 200 meters in diameter and generate a 'clean' (debris-free) tornado stretching 20 kilometers into the sky able to coax 20 megawatts each out of ten independent turbines. Obviously the main concern about the anticipated $60 million project -- which would reportedly operate at just a quarter of the cost of a coal-based facility, even before taking into account the $20 million saved on a cooling tower by the participating power plant -- is that the tornado could somehow escape its confines and wreak havoc on nearby communities. Still, with all the advantages this scheme seems to offer, we're certainly willing to give it a chance -- after all, a 'malfunctioning vortex engine' is a lot less scary than a potential disaster at one of the many nuke plants dotting our landscape.[Via UberReview]
