If you and your spouse are constantly fighting, there may be a cause that makes a little more sense than whether somebody remembered where the serving spoons go. One psychologist thinks it might have to do with blood sugar. But the weird part is how he arrived at that idea.
In the 1980s, manufactures began making cockroach baits that combined sweet glucose with deadly insecticides. By 1993, many cockroach populations somehow developed an aversion to the bait. Now, 20 years later, scientists finally understand how the roaches beat these traps.
The opalescent wings of the Morpho butterfly embody a perfect marriage of aesthetic beauty and biological functionality. Scientists believe that a better understanding of this creature's wings and their chemical makeup could have big implications for imaging technologies like night vision goggles that rely on sensing…
Spectrometers may allow people to scan themselves instead of sticking themselves. Yes, laser technology is now acquiring the companion technologies necessary to help diabetics stop having to poke themselves full of holes in order to stay alive.
Many diabetics endure daily finger pricks to test their blood sugar levels. But advances in nanotechnology could soon mean that diabetics need endure the needle only once: to get a glucose-tracking tattoo.
For diabetics, finger pricking could be a thing of the past. A biochemical engineer has developed contact lenses embedded with nanoparticles that react with the glucose in tears. As glucose levels change, so does the color of the lens. [PopSci]
