Physicists Devise Magnetic Shield

sciencehabit writes "The sneaky science of 'cloaking' just keeps getting richer. Physicists and engineers had already demonstrated rudimentary invisibility cloaks that can hide objects from light, sound, and water waves. Now, they've devised an 'antimagnet' cloak that can shield an object from a constant magnetic field without disturbing that field. If realized, such a cloak could have medical applications, researchers say."

Landmines. Right now, they use a bare minimum of metal to evade metal detectors, so everything is mechanical. This would allow a processor and such to be in the mine so you could have it not detonate on friendlies, and deactivate itself/start beeping after a couple years. Heck, you could even have the mines networked so the whole field detonates simultaneously when it detects large number of troops are half-way across. I'm not sure if it's in the best interest of humanity to revisit this technology, but at least some of their tactical and humanitarian problems can be addressed.
