'Stealth' material hides hot objects from infrared eyes
Infrared cameras are the heat-sensing eyes that help drones find their targets even in the dead of night or through heavy fog.
Hiding from such detectors could become much easier, thanks to a new cloaking material that renders objects -- and people -- practically invisible.

Electrons can be a persuasive bunch, or at least, a talkative bunch, according to new work from John Berry's lab at the University of Wisconsin-Madison.
The spins of unpaired electrons are the root of permanent magnetism, and after 10 years of design and re-design, Berry's lab has made a mo ... more
