The Promise of Nanotechnology: Delivered


After all the talk about how nanotechnology is going to remake the world it has finally done just that. Well, sort of. Cal Tech scientists have produced a DNA map that resembles the Americas.

"The mini-map measures just a few hundred nanometres (billionths of a metre) across, smaller even than some bacteria - a scale of 1:200 trillion." The lead scientists write in the journal Nature that "their technique could find uses in the the emerging field of nanotechnology." Not clear on exactly what those uses might be, but they did also produce an evil Wal-Mart icon a smiley face.

In a possibly more practical development, nanotechnology is being used to return sight to hamsters that were previously blind.
