With nanotechnology yielding a burgeoning menagerie of microscopic pumps, motors, and other machines for potential use in medicine and industry, here is one good question: How will humans turn those devices on and off?

Landmark poll shows little knowledge of emerging technologies

harminka — Tue, 30 Sep 2008 06:37:59 -0500

A groundbreaking poll finds that almost half of U.S. adults have heard nothing about nanotechnology, and nearly nine in 10 Americans say they have heard just a little or nothing at all about the emerging field of synthetic biology, according to a new report released by the Project on Emerging Nanotechnologies (PEN) and Peter D. Hart Research. Both technologies involve manipulating matter at an incredibly small scale to achieve something new.

New sensitive nanotechnology test for chemical DNA modifications
