"This could either be that one giant leap, or just another in a long sequence of multidirectional small steps on the Quixotic quest for undetectability. So-called dc metamaterials are the chief culprit for inciting our interest anew, as researchers from Universitat Aut&amp;ograve;noma de Barcelona have found a way to use them to render metallic objects invisible to low frequency electromagnetic waves. Composed of irregular networks of superconductors, the metamaterials are capable of granting superpowers altering the magnetic field of materials, and in theory, this advance could aid magnetic imaging in medical settings and also help cloak military vessels from magnetic detection. Of course, there's still the whole \"oh, now we need a working prototype\" conundrum, but hey, at least we've got the gears turning in the right direction.[Via PhysOrg]"^^<http://www.w3.org/2001/XMLSchema#string>
