(Newser) – Two teams of researchers say they're getting close to making a perfect invisibility cloak a reality, the BBC reports. The scientists—using a silicon-based material that eliminates the flaws of earlier, metal-based efforts—successfully made objects invisible at optical wavelengths by bending light around them and producing the illusion of a flat surface. It's a "big step forward," said one scientist involved in the work.
