Mechanical Engineering Magazine continues its year-long series focusing on nanotechnology. The latest installment ("Not without engineering," April 2001) is recommended by Giff Constable, who saw a notice about it in Tim Harperís TNT Weekly newsletter. GC writes: "For those heavily involved in nanotech issues, it will be old hat, but I thought it was one of the better written overviews I've seen, speaking as the non-scientist I am. The article was written by Arun Majumdar (professor and vice chair for instruction in the Department of Mechanical Engineering at the University of California, Berkeley [and] also member of the ASME Nanotechnology Steering Committee).

This series emphasizes the growing interest in a variety of engineering disciplines in the challenges of developing molecular nanotechnology. Past articles in the ME series appeared in the January and February, issues.

A quick look of nanotechnology activity in and around the U.S. capital can be found in this short article in Washington Techway ("Nanotechnology: The tiny world of atoms," by A. Daniels, April 9, 2001). The article presents a regional view of nanotech policy and research in Washington, D.C. and nearby academic and government research centers in Virginia and Maryland. The article quotes Senior Associate Richard Smith, director of forecasts in science, technology, and engineering for Coates & Jarratt, Inc., in Washington, as well as officials from NSF, NIST, and MITRE.

Note: in the accompanying illustration of Drexlerís design for a fine-motion controller, the caption erroneously states "Drexler . . . has constructed a detailed molecular manipulator". This is incorrect. The FMC has only been modeled, not constructed . . . yet.

Although the editors of Science have generally taken a dim view of the prospects for advanced nanotechnology, somebody at American Association for the Advancement of Science (AAAS) is taking the potential ethical and socioeconomic impacts seriously. The debate over genetics, nanotech and robotics (GNR) technologies sparked by Bill Joy's notorious article in Wired last year formed a major section in the AAAS Science and Technology Policy Yearbook 2001, which is a retrospective look back at 2000.

In addition to the full text of Joyís article from Wired ("Why the Future Doesnít Need Us," April 2000), a special section of the Yearbook on "Technologyís Impact on Society" includes responses by John Seely Brown and Paul Duguid from The Industry Standard ("A Response to Bill Joy and the Doom-and-Gloom Technofuturists," 13 April 2000); a piece by Michael Dertouzos of MIT that appeared in Technology Review magazine ("Not by Reason Alone," September/October 2000); and an paper by Michael M. Crow and Daniel Sarewitz of Columbia University on "Nanotechnology and Societal Transformation" that was presented at the National Science and Technology Council Workshop on Societal Implications of Nanoscience and Nanotechnology held in September 2000.

The full AAAS Yearbook, as well as these individual items, are available online as Adobe Acrobat PDF files. There are also some interesting sections on the genetic modification of foods, and the impacts of information technologies.

Senior Associate Richard H. Smith presents a brief overview of the potential of nanotechnology in a cover article in Modern Drug Discovery ("Nanotechnology gains momentum," April 2001), an publication of the American Chemical Society.

Smith, who is director of forecasts in science, technology, and engineering for Coates & Jarratt, Inc., in Washington, DC., writes: "Given a continuation of current trends, a truly potent nanotechnology will likely be realized within a decade or two. It could come in the form of exquisitely precise top-down procedures, such as moving molecules around with tiny robotic 'hands', or through a massively parallel bottom-up process, such as replicating cells."

After covering a variety of short- and medium-term research and development initiatives and discussing the potential long-term possibilities, Smith concludes: "That nanotechnology, even self-assembly with intentionality, is a serious field is no longer in doubt. But how to sort useful forecasts from unsupported conjecture remains a challenge. Are artificial immune systems worthy of discussion, or should we stick with whatís here and now? Should we fund only near-term deliverables and needed infrastructure, or challenge ourselves to keep investigating speculative but beneficial possibilities? The answer is easy: We should do both."
