A silicon tip with a sharp apex, 100,000 times smaller than a sharpened pencil, is placed in the centre of a prototype of an IBM NanoFrazor 3D nano printing tool at a laboratory of IBM Research in Rueschlikon, near Zurich, April 23, 2014. A laboratory in Switzerland has created the smallest magazine cover in the world, using a tiny chisel to create an image so minute that 2,000 of them could fit on a grain of salt. Scientists carved the 11x14-micrometre image of two pandas that appeared on last month's cover of the National Geographic Kids magazine onto a polymer using technology similar to 3D printing.
