Researchers find 12 easily captured near-Earth asteroids
Both NASA and Planetary Resources dream of capturing asteroids, but they need viable targets -- many space rocks aren't easily moved. The University of Strathclyde just gave those organizations some help by identifying 12 near-Earth asteroids that are relatively easy to catch. All of them would require velocity changes of less than 1,640 feet per second to fall into orbit around Earth's Lagrangian points, where the gravity balance would let miners and researchers get to work. Don't expect intercept missions anytime soon, though. One of the more accessible targets, 2006 RH120, would have to be nudged in February 2021 to reach orbit in 2026; it will be a long while before any of us sees an asteroid up close.
Robo-fish swim into the ocean's funk, so you don't have to
Gene Roddenberry would have you believe that space is the final frontier. But really, the deep blue sea is more apt for that distinction. And without mega-rich hobbyists to fund exploratory plunges into those uncharted depths, science has had to seek out an alternative, more cost-effective means. Enter the robotic fish. Measuring five feet in length (1.5 meters), lasting up to eight hours and costing about $32,000 (£20,000), these cyborg swimmers are made to boldly go where no man should -- that is, into contaminated waters. The project -- a joint collaboration between the University of Essex and Strathclyde, the Tyndall National Institute and defense contractor Thales Safare (cue ominous Jaws soundtrack) -- aims to cut down on the time it traditionally takes to collect samples and determine corresponding levels of water pollution. The sensor-laden bots apparently swim just like the real thing and, if a recent trial off the coast of Gijon, Spain pans out, could very soon "school" their mass-produced way into other maritime endeavors. No word on whether these automated pesce will be able to detect the piscio in your pool, but there's always the purple water for that.
Nanotech-enhanced 'smart paint' promises to detect structural damage
We've seen scientists explore a number of ways to make paint "smarter" over the years, and now a team of researchers at the University of Strathclyde in Glasgow have devised a method that they say could do nothing short of "revolutionize structural safety." The key to that is some novel nanotechnology that effectively turns the paint into a sensor network that's able to detect minor structural faults before they become a severe problem. More specifically, the paint consists of a mix of highly aligned carbon nanotubes and a recycled waste material known as fly ash -- when the nanotubes bend, the conductivity changes, indicating that there could be a structural problem developing. What's more, the fly ash is also said to give the paint a cement-like structure, which the researchers say could let it be used in harsh conditions where traditional structural monitoring can prove difficult (and expensive).
New inspection bots inspired by bat sonar
With all the world domination posturing by robots, you wouldn't think they'd be so dang good all this humanitarian and safety-related stuff, but it seems if they aren't busy pulling somebody out of a building, they're inspecting those very buildings for structural integrity. These new bots by the University of Strathclyde fall into that latter category, and use bat-inspired echolocation to navigate and inspect their surroundings. The robots report back to a mission control computer which manages the group of robo-inspectors based on the collective findings. There's also a camera on board each bot, along with a magnet to test for corrosion. It doesn't look like these bots will make it to market for another 10 years, but when they do they're expected to make the job of inspecting nuclear installations and gas pipelines a whole lot more fun.
