The Mighty Nose
The human nose is an amazing biological detecting device. In the nose alone, there are over 400 olfactory sensors capable of discriminating between roughly 1 trillion scents.
Our sense of smell is connected directly to more primitive parts of our brain. Smell information is then integrated with taste information, to provide a more comprehensive experience of eating a fine meal.
But the olfactory sense is not limited to our noses. Olfactory sensors or receptors can be found in our livers, hearts, kidneys, colons, brains, skin and even testicles. Recent research shows that olfactory receptors in our kidneys work with our friendly bacteria (our microbiome) to help control high blood pressure.
So maybe it’s time not to turn up our noses at our neglected olfactory sense.
Cool Your House For Free
Reasearchers Yin and Yang (really) at the University of Colorado at Boulder have developed a new “metamaterial” that very efficiently reflects incident radiation. More importantly, the material also efficiently reradiates energy trapped below it.
The material can be supplied in convenient roll form, and costs about 50 cents per square meter. While only 50 microns thick, the material is said to reduce the interior temperature of a house by 17 Celsius degrees without the need for any external energy or water cooling input.
The material takes advantage of embedded 8 micron diameter glass spheres that resonate and reradiate incident energy at an infrared frequency that naturally passes through our atmosphere on its way out to space.
Anticipated applications of this metamaterial include power plants, and homes.
