This sounds great: the Biomolecular Nanotechnology program at Arizona State. Work on "logic gates made from single molecules, molecular motors that move fluids in chip-sized laboratories, sensors based on cells interfaced to processors, artificial cells with chemical functionality and solar power" applied to "making molecular processors that can be incorporated directly into clothes, paint or plastics." Solid funding, international travel, industrial internships, attending nanoconferences. Also: "students in our program will explore the political and societal mechanisms by which decisions concerning science funding and policy are made and what impacts these decisions have had on society in the past." They'll need strong stomachs for that part! Making legislation is like making sausage; it can be more comfortable not to know. –CP

Betterhmans is reporting on progress of scientists at USC in combining several nanoscale technologies (transferrin based transport vehicles with small interfering RNA segments (siRNAs)) to effectively combat cancer, in this case Ewing's sarcoma, a type of cancer which impacts children. Interfering RNAs are small RNA strands which preferentially bind to complementary messenger RNA (mRNA). This activates cellular processes, presumably evolved to defend against double stranded RNA viruses, that destroy the double stranded RNA effectively reducing or eliminating the activity of the protein normally produced by the specific mRNA targeted by the siRNA.

The article with links to background information is here. There is significant potential for using this type of therapy to combat other types of cancer where the overexpression of a specific gene or protein is the primary cause of the disease.

While this is not diamondoid molecular nanotechnology it it can legitimately be considered molecular nanotechnology because it is nanoscale, it is based on precision activity at the nanoscale level and takes advantage of molecular processes and machinery normally found in cells.

Many Nanodot readers may be able to make the case to their employers that they need to understand the future of manufacturing. Take a shot at it now, so you can attend "Molecular Nanotechnology and Manufacturing: The Enabling Tools and Applications" on May 4 in Minneapolis, sponsored by the Society of Manufacturing Engineers. Speakers on molecular manufacturing include David Forrest and Chris Phoenix. Jim Von Ehr will speak on "Assembly Pathway to Nanotechnology: Meso to Micro to Nano". Other talks will likely include relevant info, e.g. IBM's Thomas Theis: "Over the next few decades, it should become possible to design and control the structure of an object at all length scales, from the atomic to the macroscopic, and to do so cheaply and reliably in manufacturing." Foresight president Scott Mize will meet with Foresight Senior Associates members that evening; contact the office to sign up.

Keith Gillette writes "Nanotechnology research at the University of Wisconsin–Madison provides the subject for the cover story of the Spring 2005 edition of On Wisconsin , the UW-Madison alumni magazine. From the examples used, the article appears to use the term nanotechnology in its popular sense, drawing no distinction with molecular nanotechnology."

Mike Treder writes "SUMMARY: The popular idea of so-called nanobots, powerful and at risk of running wild, is not part of modern plans for building things ìatom-by-atomî by molecular manufacturing. Studies indicate that most people don't know the difference between molecular manufacturing, nanoscale technology, and nanobots. Confusion about terms, fueled by science fiction, has distorted the truth about advanced nanotechnology. Nanobots are not needed for manufacturing, but continued misunderstanding may hinder research into highly beneficial technologies and discussion of the real dangers.

The February 2005 issue of NanoNews Now focuses on molecular nanotechnology, including interviews with Scott Mize of Foresight, Mike Treder and Chris Phoenix of CRN, and Doug Parr of Greenpeace — see excerpts on their homepage. Also includes Foresight Senior Associate Pearl Chin's column on nanotech investing. Single issues are $19.95, but you can view the current issue at no charge by signing up for their free email newsletter, NanoNews Digest (click on "Your Account" on the thank you page to set up an account). Or, get a 90-day free trial by subscribing to NanoNews Now itself.

Wikipedia is an free online encyclopedia written cooperatively using WIKI technology. Their nanotechnology entry seems to need tweaking: the illustration appears to be of MEMS, not nanotech. Those of you familiar with this community: please help them out by suggesting a more appropriate graphic. (The molecular nanotechnology entry needs a graphic too.)
