"Computing with Molecules" in Scientific American

from the OK-so-it's-not-our-favorite-magazine dept.
BradHein writes "Scientific American has an article titled Computing with Molecules by Mark Reed and James Tour. The article covers Reed and Tour's work with molecular electronics. Some of the topics include current day research challenges in working with self assembly, combining molecular systems with conventional electronics, and creating complex molecular devices."

Reputation-based Idea-Futures-style investing

from the talk-about-"Group-Genius"(TM) dept.
Senior Associate Charles Vollum writes "When I entered the Mutual Minds web site, I thought I'd been transported to the world of Earth Web…A mutual fund whose stocks are selected by the best forecasts of its investors. According to the FAQ, "Participants visit the site and predict future stock prices. Over time, forecasts are compared against actual stock prices and each participant earns a score that reflects their historical performance. A computer model combines the forecasts from all participants that are invested in the fund based on their scores. The combined forecasts determine the investments for the fund (those with the highest risk adjusted return potential). The forecasts are used by a portfolio optimizer similar to those used by fund managers today to determine what % should be invested in each security. The result is a well-diversified portfolio consisting of the preferred investments of the community." CV: It will be interesting to see how this works out."

Self-replicating distributed security agents

from the software-immune-system dept.
JohnPierce reports on work at Sandia: "A thought-provoking article on software security agents. They are self-replicating, and work in a social structure. These may be precursors to AI and distributed control of swarms of nanomachines."

Brain-scan technology detects emotion of love

from the do-you-love-me?-better-tell-the-truth dept.
BBC reports that researchers at University College London have been able to detect the emotion of love using brain scans. Dr Andreas Bartels said: "I'm convinced that we can use it as a test for love — however, it's rather an expensive one!" Oh, well, that's all right then.

Biotech's troubles: Lessons for Nanotech

from the technology-for-all-not-just-the-rich dept.
Senior Associate BryanBruns reports "A well-written white paper on Transgenic Plants and World Agriculture argues that farmers in poor countries need better access to plant biotechnology. A working group from the US National Academy of Sciences the Royal Society of London, and scientific academies in other nations prepared the paper. (See also stories in the Washington Post and NandoTimes). This paper offers good examples of thinking through how to steer technology so it can benefit farmers and others in poor countries, not just commercial interests in wealthy countries. The report encourages better sharing of intellectual property. The whole report is worth reading, if you are interested in preparing society for advanced technologies, but if you're pressed for time you could look at the summary and the chapter on intellectual property".Read More for Bryan's full post.

STM triggers nanoscale self-assembly

from the those-clever-Canadians dept.
Senior Associate GinaMiller points out a report from the NRC on their breakthrough work using a scanning probe to stimulate the automatic self-assembly of organic molecules into lines on a chip surface: While much work remains to be done, they are optimistic about the prospects of nanotechnology…"The appeal of the technique is that we've limited the need for arduous atom-by-atom crafting of structures with an STM, and unleashed a spontaneous process to automatically drive nanostructure growth…" See their animation.

Nanotech: Open Source or Proprietary?

from the Drexler-says-"Let's-patent-matter-&-its-use" dept.
Paul Hughes reposts from Transdot: It's quite possible the assembler won't be for sale, at least not to the general public. Large companies who can afford a 10-50 billion dollar price tag, may likely obtain licensing rights for its use, but that's a far cry from the average joe owning it…Hopefully, the first company to develop this assembler will not obtain all-inclusive patent rights thereby allowing a sufficient number of competitors to enter the race. Read More for the full post and a response.

Nanoweapons = chemical weapons?

from the OK-so-they're-BIG-chemicals dept.
MarkGubrud has pointed out that the 1996 Chemical Weapons Convention includes a strong verification, monitoring, and challenge inspection system (unlike, say, the 1972 Biological Weapons Convention). Given this, I wonder whether it wouldn't be easier to have nanotech weapons classified as a (large) form of chemical weapon, rather than writing a whole new treaty which would then need to be adopted?

DARPA research effort in molecular electronics

from the Rice-calls-it-"Moleware" dept.
TomKalil writes "DARPA has recently released a call for proposals in molecular electronics (MoleTronics). One of the technical goals of the program is to demonstrate densities of 1011 devices/cm2. See link for a description of existing DARPA-funded research on molecular electronics at HP and UCLA, Rice, Notre Dame, Harvard, Penn State, etc." From the call for proposals: "The second task is hierarchical self-assembly, i.e., bridging the nano- to the micro-worlds. This can be described as a set of processes that will first assemble individual devices, then create functional nano-blocks (e.g., memory and/or logic) from those devices, and finally the interconnection amongst said nano-blocks to form computationally functional circuits (modules) with a reasonable input and output methodology. Innovative interconnect and input/output concepts (e.g., multiplexing and demultiplexing schemes) are solicited."

Fling: Making DNS, TCP, and UDP Untraceable

from the bits-from-the-underground dept.
"Fling is a new suite of internet protocols that perform the function of DNS, TCP, and UDP in a manner that's both untraceable and untappable. Fling protects clients from servers, servers from clients, and both from an eavesdropper in-between. The result is that anyone can serve or retrieve any data, without fear of censure." I haven't given the technical description of the protocols more than a once-over; does anybody see a fundamental problem with them?
