We've already seen radars come in handy when dodging impending attacks and avoiding accidents, but researchers at MIT are utilizing the technology to make sure our roadways and structures aren't pushed beyond their limits. A newfangled handheld device uses FAR-NDT (far-field airborne radar nondestructive testing) in order to "see through the fiberglass-polymer wrapping often used to strengthen aging concrete columns to detect damage behind the wrapping not visible to the naked eye." Furthermore, the technique can be executed from about 30 feet away and "requires no dismantling or obstruction of the infrastructure" in order to provide instant feedback. Unsurprisingly, creators are suggesting that it will be best used on bridges and piers which are typically difficult to carefully inspect, and while there's no word on when this stuff will hit DOT offices nationwide, current prototypes are panning out quite well.

You've got plenty of options when it comes to healing your own body, but patching up your domicile usually requires days of back-breaking labor and gobs of cash to boot. Thankfully, that awful process could be nearing its end, as a £9.5 million ($18.64 million) European Union-funded project sets out to develop self-healing walls for your average home. The idea is to develop "special walls for the house that contain nano polymer particles, which will turn into a liquid when squeezed under pressure, flow into the cracks, and then harden to form a solid material." The technology would prove quite useful in areas where earthquakes are prominent, and in an effort to test things out before shoving it out to contractors everywhere, a swank villa is being erected on a Greece mountainside to collect information. The house's walls will be built from "novel load bearing steel frames and high-strength gypsum board," but more importantly, they will contain a smorgasbord of wireless sensors and RFID tags meant to collect, store, and disseminate critical data regarding "any stresses and vibrations, temperature, humidity, and gas levels." Now, who's the lucky lad(s) that get to call this their home research dwelling?
