Super Spinach Bet you didn't know just how good spinach could be for you. Scientists at MIT have found a way to give spinach a Popeye-like boost, lacing the leafy greens with nanotubes—then turning the plant into a sensor of its own, able to pick up on potential explosives. The information is then sent wirelessly to handheld device—like your smartphone or even smaller—alerting authorities. The plants specifically detect a chemical called nitroaromatics from the ground water where the spinach grows. When detected, the presence makes the spinach give off a fluorescence. Researchers are already looking at different ways plants could be used to read the environment—and read by our IoT devices. (Via MIT News)

But socks...will be first on our list. (Via TechCrunch)
