Zyvex in Red Herring

from the nanobusiness-in-the-news dept.
Foresight advisor and Zyvex researcher Ralph Merkle points out an Oct 5 column on nanotechnology on the site of business magazine Red Herring: For decades, skeptics have dismissed molecular nanotechnology as the dream of crackpots, fools, and technology visionaries. The skeptics were wrong…in the last two years, there have been new discoveries that may revolutionize the fields of medicine, microprocessors, and synthetic materials. Discoveries such as Northwestern University's new nanolithography techniques used for designing transistors smaller than a molecule, Cornell University's work on how to turn a living cell into a motor, or NASA's progress on the development of carbon nanotubes — super-strong, lightweight materials for use in future spacecraft. Nanotechnology, it seems, is progressing from the science fiction of books like Neal Stephenson's Diamond Age to science fact. Most of the piece is on the company Zyvex, which is working on both bottom-up and top-down approaches.

Tihamer Toth-Fejel on Abuse of Power

from the assemblers-actualizing-Acton's-axiom dept.
Jonathan Desp calls attention to a position paper by longtime Foresight friend Tihamer Toth-Fejel of the NSS's Molecular Manufacturing Shortcut Group, entitled "The Abuse of Power on the Eve of the Nanotechnology Revolution". From the paper's position statement: "Taking to heart Lord Acton's admonition that power tends to corrupt, we wish to take the necessary precautions so that humanity survives the coming revolution in molecular nanotechnology." The paper is hosted on Jonathan's Atomasoft site.

MNT & space dissertation needs reviewers

from the let's-help-change-Mr-Tom-to-Dr-Tom dept.
Senior Associate Tom McKendree writes "I am wrapping up the last substantive chapter of my dissertation [on space applications of molecular nanotechnology]. After that, I still have the conclusions chapter to finish, and the introduction to write, but there is a lot of content in what is already done. My target is to actually defend and complete this year. So, in the spirit of parallel processing, I am looking once again for people interested in reviewing sections of the dissertation."

Ask Nanodot: Open Sourcing Nanotechnology

from the safety-through-openness dept.
Senior Associate BryanBruns writes "I've posted a working draft of a paper on "Open Sourcing Nanotechnology" that I'm preparing for a poster presentation at the November MNT Conference. I've found a lot of interesting stuff, which I try to lay out in the paper, but have some questions where I'd like to ask what ideas and suggestions others may have…[see "Read More" for the specific questions and an abstract]…I'm coming at this as a sociologist, with some background in economics and computers, but not an expert in nanoscience. I'd welcome comments, either directly to me ([email protected]), or here on Nanodot if you think they would be of general interest. The NanoCAD mailing list offers a continuing forum for discussion of molecular modeling software." Read more for the full post.

protein mechanics from neutron diffraction

from the atomic-age-MNT??? dept.
Neutron scattering has been used to quantify thermal positional disorder in proteins. In myoglobin, there is a transition at ~200K from a "harmonic" regime where all the atoms are trapped in single potential wells to an anharmonic regime where jumps between wells become important. The anharmonic regime is important for the biological function of myoglobin (O2 binding), but may cause problems for use of proteins as mechanical elements in nanotechnology.

Feynman Prize in Nanotechnology finalists

from the wish-he-were-here-to-see dept.
The top five individuals or teams in two categories, Experimental and Theoretical, have been selected as finalists for this year's Feynman Prizes in Nanotechnology. Winners will be feted at the Feynman Prize Banquet on November 4, 2000, at the 8th Foresight Conference on Molecular Nanotechnology in Bethesda, Maryland, USA. Congratulations to these world-class nanotechnology researchers, and thanks to all who made nominations this year.

Los Angeles: MNT & Space talk, Aug 19

from the ad-astra-per-nano dept.
Senior Associate TomMcKendree will speak on space applications of advanced nanotech at the LA Nanotechnology Study Group:
Title: Appropriately Ambitious Aerospace Goals: A Reprise of the Keynote Address to NASA's "Turning Goals Into Reality" Conference
Molecular nanotechnology (MNT) offers a number of capabilities that can dramatically improve aerospace systems (such as aircraft and spaceships). Tom McKendree is completing a Ph.D. that looks specifically at space applications of MNT, and was thus invited to give the keynote to NASA's recent Turning Goals Into Reality conference, where NASA reviewed their last year of technology research, and planned for the future. This talk is a second presentation of that keynote. It focuses on MNT-based air transportation, space transportation, and advanced concepts, tying these to NASA's previously stated technology goals, and outlining what appropriate goals for the next century that take advantage of MNT would be. The talk should be interesting to anyone interested in space technology, or applications of robust MNT. Read More to attend.

0.8 nm conductive marks

from the poke-it-again-Sam dept.
Researchers have written 0.8 nm (presumably diameter) conductive marks in a thin organic film with an STM. The marks were stable for at least the 2 hour scanning session. They attribute the marks to polymerisation of the film under the STM tip.

Understanding protein structure from first principles

from the Cutting-the-gordian-knot dept.

Custom-engineered proteins have long been seen as one possible route to molecular nanotechnology. But the challenge of understanding how and why protein molecules assume the shapes they do to perform their structural and functional roles, has been an enduring problem in the field of protein engineering.

A press release describes work that apparently explains at least some aspects of protein structure by working from first principles. "We have discovered a simple explanation, based solely on principles of geometry, for the protein's preference for the helix as a major component of its overall structure," says Jayanth R. Banavar, professor of physics at Penn State and a member of the team of U.S. and Italian research physicists that made the discovery. The work was also reported in the 20 July 2000 issue of the journal Nature.

Time Magazine: nanotech benefits potentially enormous

from the Time-for-nanotech-time dept.
Senior Associate RalphMerkle reports an item on molecular nanotech not available on the web:"The June 19th 2000 issue of Time Magazine, "The Future of Technology," has a two-page article titled "Will tiny robots build diamonds one atom at a time?" by Michael D. Lemonick on page 94:"On its face, the notion seems utterly preposterous: a single technology so incredibly versatile that it can fight disease, stave off aging, clean up toxic waste, boost the world's food supply and build roads, automobiles and skyscrapers — and that's only to start with…Crazy though it sounds, the idea of nanotechnology is very much in the scientific mainstream, with research labs all over the world trying to make it work."Read More for additional quotes from this well-done article. Merkle comments: Acceptance of the core concepts of molecular nanotechnology is proceeding at an accelerating rate.
