Carbon nanoparticles stimulate blood clotting, researchers report. Both 
nanotubes and airborne particles cause platelets to clump together. 
Carbon nanoparticles - both those unleashed in the air by engine exhaust 
and the engineered structures thought to have great potential in medical 
applications - promote blood-clotting, scientists report in an upcoming 
edition of the British Journal of Pharmacology. Researchers from The 
University of Texas Health Science Center at Houston and Ohio University 
examined the impact of various forms of carbon nanoparticles in a 
laboratory experiment on human platelets - blood's principal clotting 
element - and in a model of carotid artery thrombosis, or blockage, 
using anesthetized rats. (Innovations Report 10.24.05)
Kinematic Self-Replicating Machines Now Freely Available Online. The 
most comprehensive review of the field of Kinematic Self-Replicating 
Machines (KSRM), the title of a book co-authored by Robert A. Freitas 
Jr. (http://www.rfreitas.com) and Ralph C. Merkle 
(http://www.merkle.com), was published in hardback in late 2004.  The 
book is still available in print 
(http://www.amazon.com/exec/obidos/ASIN/1570596905), but KSRM is now 
freely accessible online at http://www.MolecularAssembler.com/KSRM.htm. 
With 200 + illustrations and 3200 + literature references, KSRM 
describes all proposed and experimentally realized self-replicating 
systems that were publicly known as of 2004, ranging from nanoscale to 
macroscale systems.  The book extensively describes the historical 
development of the field.  It presents for the first time a detailed 
137-dimensional map of the entire kinematic replicator design space to 
assist future engineering efforts.  KSRM has been
cited in two articles appearing in Nature this year (Zykov et al, Nature 
435, 163 (12 May 2005) and Griffith et al, Nature 437, 636 (29 September 
2005) and appears well on its way to becoming the classic reference in 
this field.
Scientists build world's first single-molecule car. Rice University 
Scientists have done it. After BMW announced the possibility of 
producing a car that would utilize nanotechnology practically for all 
functions, Rice University scientists developed the world's first 
single-molecule car- the car that was driven on a gold microscopic 
highway. It a small coupe that is devoid of any plush seating or 
conventional steering system. But it is a real solution for the grid 
locked cities. With a wheelbase of less than 5 nm, parking it is a 
cakewalk. (Physorg 10.20.05) http://www.physorg.com/news7438.html
Richard Errett Smalley, a gifted chemist who shared a Nobel Prize for 
the discovery of buckyballs, helped pioneer the field of nanotechnology 
and became Houston's most notable scientist, died Friday afternoon after 
a six-year struggle with cancer. He was 62. Smalley possessed prodigious 
talent both within the lab, where he cobbled individual atoms together 
like tinker toys, and outside academia after he won science's greatest 
prize. In the decade since he became a Nobel laureate, Smalley pushed 
Rice University and Houston to the forefront of nanotechnology research.

Engineers Build DNA 'Nanotowers' With Enzyme Tools. Duke engineers have 
added a new construction tool to their bio-nanofabrication toolbox. 
Using an enzyme called TdTase, engineers can vertically extend short DNA 
chains attached to nanometer-sized gold plates. This advance adds new 
capability to the field of bio-nanomanufacturing. "The process works 
like stacking Legos to make a tower and is an important step toward 
creating functional nanostructures out of biological materials," said 
Ashutosh Chilkoti, associate professor of biomedical engineering at 
Duke's Pratt School of Engineering. (ScienceDaily 10.14.05) 
Foresight Awards Nanotech Prizes. The Foresight Nanotech Institute, a 
think tank and public interest organization focused on nanotechnology, 
awarded prizes to leaders in research, communication, government and 
study in the field of nanotechnology at the 13th Foresight Conference.

Modifications render carbon nanotubes nontoxic. Rice team mitigates 
toxicity of tiny cylinders with chemical changes. In follow-on work to 
last year's groundbreaking toxicological study on water-soluble 
buckyballs, researchers at Rice University's Center for Biological and 
Environmental Nanotechnology (CBEN) find that water-soluble carbon 
nanotubes are significantly less toxic to begin with. Moreover, the 
research finds that nanotubes, like buckyballs, can be rendered nontoxic 
with minor chemical modifications. The findings come from the first 
toxicological studies of water-soluble carbon nanotubes. The study, 
which is available online, will be published in an upcoming issue of the 
journal Toxicology Letters. The research is a continuation of CBEN's 
pioneering efforts to both identify and mitigate potential 
nanotechnology risks. (EurekAlert 10.26.05)
Nanotechnology seeks to detect food contaminants. Using microchips to 
detect and remove contaminants such as E. coli, anthrax or botulism from 
food may sound like Star Wars technology to some, but Larry Branen 
believes it's possible. The challenge is that researching and developing 
the necessary technology requires working with materials smaller than a 
hair. Such research even has its own name: nanotechnology. "At such 
small levels, there are changes in the properties of materials and how 
they interact. Scientifically, we must approach them in new ways," said 
Branen, associate director of the University of Idaho's Research 
Institute here. (Capital Press 10.21.05) 
Future nanotech tools made from clay. NaturalNano says that by filling 
Halloysite tubes with copper and then mixing the tubes into a polymer, a 
manufacturer could make an electrically conductive plastic. If filled 
with fungicides, the Halloysite particles--which consist of aluminum, 
oxygen, silicon and hydrogen--could be swirled into paint to make it 
more resistant to mildew and mold. Time-released coatings could also be 
added to make all-day deodorant. The tubes could even have agricultural 
uses. (Cnet 10.26.05) 
Solar cell solution: nanotechnology. One-hundred times smaller than 
bacteria, more efficient than plastic film, nanotubes prove promising at 
harvesting sun's power. If the nation decided to blanket its rooftops in 
solar cells -- generating as much as 75 percent of all electricity 
produced today -- it would be costly beyond belief and probably 
impossible: There isn't enough silicon. Scientists for 20 years have 
searched for an answer in very thin, plastic films, something that could 
be rolled out nationwide for a few cents per square foot. But they 
haven't proved very efficient at harvesting the power of the sun and 
tend to break down in air and sunlight.

$35 Million in Awards to 12 Cancer Nanotechnology Platform Partnerships. 
The National Cancer Institute (NCI), part of the National Institutes of 
Health (NIH), today announced funding for a major component of its 
$144.3 million, five-year initiative for nanotechnology in cancer 
research. Awards totaling $35 million over five years, with $7 million 
total in the first year, will establish 12 Cancer Nanotechnology 
Platform Partnerships. (Azonano 10.18.05) 
Physicists have observed the Jahn-Teller effect in a molecule for the 
first time. The effect was seen in carbon-60 molecules doped with 
potassium. The results could shed more light on the fundamental 
properties of molecular nanostructures (Science 310 468)."The 
Jahn-Teller effect has long been known to play an important role in the 
relationship between the structure of molecules and their energy levels, 
but this is the first time anyone has directly imaged it at the 
single-molecule level," says Mike Crommie of the University of 
California at Berkeley and the Lawrence Berkeley Laboratory, leader of 
the team that saw the effect. (nanotechweb 10.24.05) 
Nanotechnology targets new food packaging products. Exciting new 
nanotechnology products for food packaging are in the development 
pipeline or, as in the case of anti-microbial films, have already 
entered the market, according to a report published this month by an 
EU-funded research team. "While far reaching visions such as nanotech 
food synthesizers or pathogen killing nanobots are not expected to 
become reality within the next decades, nanotechnology related R&D for 
food processing, food engineering and food packaging is in the 
innovation pipeline of the food industry today," the team said.

Center on Nanotechnology and Society Created at IIT. A nearly $500,000 
Congressional earmark is helping fund the creation of the Center on 
Nanotechnology and Society at the Illinois Institute of Technology. 
Housed in IIT's Chicago-Kent College of Law, the Center will examine 
legal, social and ethical implications of nanotechnology. (nanotechwire 
Ford, Boeing and Northwestern Form Nanotechnology Alliance. Ford Motor 
Co., The Boeing Co. and Northwestern University have big plans to work 
together to make the future very small. The two companies and the 
university are in final negotiations to form a new alliance to research 
commercial applications of nanotechnology, the branch of engineering 
that deals with things smaller than 100 nm and at the molecular level. 
Ford and Boeing will each provide financial support for three years, and 
Northwestern's Robert R. McCormick School of Engineering and Applied 
Science will provide administration of the alliance and office space for 
a full-time Ford employee who will serve as the industrial alliance 
coordinator. (Photonics 10.1205) 
Engineers at Purdue University have shown how researchers might better 
use tiny hollow fibers called "multi-walled carbon nanotubes" to more 
precisely measure structures and devices for electronics and other 
applications. Findings will appear in the November issue of the journal 
Nanotechnology. Researchers attach the tubes to the ends of imaging 
instruments called atomic force microscopes. Because the tubes are long 
and slender, their shape is ideal for the emerging field of 
"nanometrology," which is precisely measuring structures on the scale of 
nanometers, or billionths of a meter. (Physorg 10.12.05) 
Nanotechnology Emergence Generates High Expectations, Expert Says. 
Independent oversight of research needed to address any health hazards. 
The following article appears in the October 2005 issue of the State 
Department's electronic journal Economic Perspectives. It is based on an 
op-ed article published on the Pennsylvania State University Internet 
site but has been revised and updated by the author for this 
publication. The complete issue, titled The Promise of Biotechnology,

Think small, dream big" is a typical slogan about the promise of 
nanotechnology within the scientific research community. Once relegated 
to pure fiction, nanotechnology is becoming increasingly linked with 
advances in biotechnology and information technology. With annual 
expenditure for nanotechnology research in the United States estimated 
to be in excess of $2.6 billion in 2004, the word "nano" is even finding 
its way into popular culture, from daily horoscopes to newspaper 
cartoons. (USINFO.STATE.GOV 10.27.05)
Proofreading and error-correction in nanomaterials inspired by nature. 
Mimicking nature, a procedure developed by researchers at the University 
of Illinois at Urbana-Champaign can find and correct defects in 
self-assembled nanomaterials. The new proofreading and error-removal 
process is based on catalytic DNA and represents a paradigm shift in 
nanoscale science and engineering.

Nanomanufacturing: First Systematic Study Of Cadmium Selenide 
Nanostructure Growth Yields Production 'Road Map'. Researchers have 
taken an important step toward high-volume production of new 
nanometer-scale structures with the first systematic study of growth 
conditions that affect production of one-dimensional nanostructures from 
the optoelectronic material cadmium selenide (CdSe). Using the results 
from more than 150 different experiments in which temperature and 
pressure conditions were systematically varied, nanotechnology 
researchers at the Georgia Institute of Technology created a "road map" 
to guide future nanomanufacturing using the vapor-liquid-solid (VLS) 
technique. (ScienceDaily 10.30.05) 
Nano skyscrapers may precede space elevator. Liftport, a 
space-infrastucture company, has been among those who support 
construction of a space elevator, a long thin cable made of carbon 
nanotubes anchored to a platform or ship at sea and extending out into 
space. Held in place by the earth's rotation, the space elevator, with 
the help of robots, would ferry materials to outer space.
