In Popular Mechanics, longtime Foresight friend Prof. Glenn Reynolds looks at the future of nanotech and artificial intelligence, among other things looking at safety issues, including one call that potentially dangerous technologies be relinquished. He takes a counterintuitive stance, which we’ve discussed here at Foresight over the years: Ted Greenwald posted yesterday at Wired about Foresight member Ralph Merkle’s presentation on nanotechnology at the Singularity University’s first Executive Program, which has just convened over at NASA Ames here in Silicon Valley: Nanotechnology Enables Real Atomic Precision is the title of a piece by Susan Smith in Desktop Engineering, which includes comments by longtime Foresight Senior Associates Steve Vetter and Tihamer Toth-Fejel: From Physorg.com: Russian Academy of Sciences have developed a method of nanofabrication using an atom pinhole camera…. The technique could produce individual nanostructures down to 30 nm, a size reduction of 10,000 times compared with the original object. From The Gulf Times via Nanowerk: A catalyst can be switched on and off using mechanical means. A piece in The Christian Science Monitor compares Nadrian Seeman, founder of the field of structural DNA nanotechnology and winner of the 1995 Foresight Feynman Prize in Nanotechnology, with Henry Ford—implying that his recent accomplishment with his collaborators in creating a two-armed DNA nanorobot could point to a role for DNA nanorobots in future nanotech [...] Jeriaska has made available videos of presentations from Convergence08, held on November 15-16, 2008 in Mountain View, California, to examine the convergence of NBIC (Nano-Bio-Info-Cogno) technologies. Among those of special interest to Nanodot readers: Mapping a Cone of Uncertainty, Paul Saffo The January issue of Life Extension Magazine offers a report on the eventual promise of medical nanobots. The ribosome has a previously unsuspected method of error correction—in this case monitoring the fidelity of protein synthesis after the peptide bond is formed. The answers of 151 thinkers and visionaries to the Edge Annual question for 2009 have been posted. The question: “WHAT WILL CHANGE EVERYTHING?” As phrased by John Brockman, Editor and Publisher, “What game-changing scientific ideas and developments do you expect to live to see?” In his answer, nanotechnology pioneer Eric Drexler points to a role [...] One of the main reasons that we are confident in the overall predictions of molecular manufacturing is that there are many pathways to it from current technology and using currently understood science. It is thus something of a milestone that we have arrived at a fork in the road about which there is room for [...] The following is an edited and revised version of the talk I gave at the Global Catastrophic Risks conference that was held in conjunction with Convergence 08 (and which I reprised for Convergence). I’m posting it here because it seems to me that this is exactly the kind of thing Foresight was founded for: to [...] Arrays of atomic force probe tips are promising nanotech approaches to denser, faster, cheaper memories. Re-engineering a simple nanotech device to make it more functional, Chinese scientists have developed an improved DNA tweezers that is able to capture, hold, and release a target molecule in a controlled manner. Robert A. Freitas Jr. brings to our attention a major step on the road to advanced nanotech, published a couple weeks ago in Science (abstract). He writes: This paper reports purely mechanical-based covalent bond-making and bond-breaking (true mechanosynthesis) involving atom by atom substitution of silicon (Si) atoms for tin (Sn) atoms in an Sn monolayer surface [...] You might think that by now the definitions of terms like “nanotechnology” and “nanosystems” would be firmly established. In fact the process of arriving at an international consensus is more difficult than you might expect. Representing Foresight in the effort to define these and other terms is David R. Forrest, Ph.D., President of the Institute [...] On 5 June 2008, Robert Freitas and Ralph Merkle of the Institute for Molecular Manufacturing (IMM) submitted to IEEE Spectrum the following response to the article “Rupturing the Nanotech Rapture” by Richard A.L. Jones (IEEE Spectrum, June 2008 issue). Their brief letter is reproduced below because Spectrum has chosen to publish only one of [...] DARPA and a Texas fund have awarded $9.7M to investigate one nanotech path toward atomically precise manufacturing. A pioneering UK program aimed at developing a nanofactory has made a £1.53M ($3M) award to Professor Philip Moriarty of the University of Nottingham to support a five-year series of experiments to investigate the possibility of diamond mechanosynthesis, testing the theoretical proposals recently made by Robert Freitas and Ralph Merkle. Details are contained in the [...] |
