By their very nature, microchips are little bitty things, but scientists wants to make them downright invisible – and they’re getting pretty close! A team from IBM just announced some solid progress in using carbon nanotubes to replace the transistors that currently allow microchips to process information. Because they’re about as conductive, they can carry an electric signal just like the silicon we use today but are a fraction of the same size. This ultimately means that you could fit 1 billion nanotubes onto a one square centimeter chip.
