A new type of X-ray microscope — or more appropriately, nanoscope — is another big breakthrough in the world of imaging the small. It computes images rather than glimpsing them directly, allowing scientists to see details at the nanoscale.
Light is essential to vision, at least the kind we perform with our naked eyes. This is why we can see through a glass lens but not through a brick wall (though we're working on that). But what about materials that let some light pass while scattering it in seemingly chaotic ways?
As if aerial robots and bionic limbs didn't make the Army seem futuristic enough, it looks like another hallmark of sci-fi, X-ray vision, will ship off to Afghanistan later this year. The device in question is the TiaLinx Eagle Scanner, which uses radio waves to see through the ground, walls, and other kinds of cover.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
