A survey of recent studies and projects to bridge the nanotechnology regulatory gap in the developing world.
A molecule-sized switch just 50 nanometers wide may someday control microscopic machines and also could make DNA sequencing faster, less expensive, and more precise.
Is it possible to make a cable for a space elevator out of carbon nanotubes? Not anytime soon, if ever, says Nicola Pugno of the Polytechnic of Turin, Italy. Pugno's calculations show that inevitable defects in the nanotubes mean that such a cable simply wouldn't be strong enough.
Two environmental activist groups have petitioned the U.S. government to pursue new regulations on numerous products such as sunscreens and cosmetics that contain potentially hazardous nanoparticles but lack adequate warning labels of their possible health effects.
"Individuals are getting more and more powerful," says author Glenn Reynolds in his insightful new book, An Army of Davids. "With the current rate of progress we're seeing in biotechnology, nanotechnology, artificial intelligence, and other technologies, it seems likely that individuals will one day -- and one day relatively soon -- possess powers once thought available only to nation-states, superheroes, or gods.
Ray Kurzweil proposes a strategy for dealing with the dangers from Genetic Engineering, Nanotechnology, and Artificial Intelligence. The strategy includes "a streamlined regulatory process, a global program of monitoring for unknown or evolving biological pathogens, temporary moratoriums, raising public awareness, international cooperation, software reconnaissance, and fostering values of liberty, tolerance, and respect for knowledge and diversity."
Scientists are on the verge of breaking the carbon barrier -- creating artificial life and changing forever what it means to be human. And we're not ready.
The author surveys an "upcoming series of academic conferences will attempt to explore whether and how nanotechnology can address the principles of green chemistry and green engineering."
WorldChanging.org has a lengthy interview with Chris Phoenix and Mike Treder of the Center for Responsible Nanotechnology, a non-profit group helping to make sure molecular manufacturing is developed as safely as possible. In the article they talk about their policy task force (which includes folks like Ray Kurzweil, David Brin, and Jaron Lanier), the risks and benefits of nanofactories, and why open source is so important to the responsible development of nanotechnology.
Amid growing evidence that some of the tiniest materials ever engineered pose potentially big environmental, health and safety risks, momentum is building in Congress, environmental circles and in the industry itself to beef up federal oversight of the new materials, which are already showing up in dozens of consumer products.
