Sandia creates MEMS device to catch blood cells

from the getting-cute-with-PR dept.
The press accounts indicate that a lot of people are just ga-ga over the silicon micro-device developed at Sandia National Labs. Described as a "Pac-Man-like microstructure" and the "gobbler", the device has silicon microteeth that open and close like jaws. The microjaws fit in a microchannel about one-third the width of a human hair (about 20 microns wide). When the jaws close, they trap a red blood cell. According to a Sandia press release on 20 August 2001, "The jaws, which open and close very rapidly, deform captured cells, and then, in less than the blink of an eye and almost playfully, let the little things loose. The blood cells travel on, regain their former shape and appear unharmed." [Playfully?]
Additional coverage can be found in this article from UPI. And Robert Trombatore writes: "A news item on the Scientific American web site details a just announced microdevice that can grab individual red blood cells flowing through a central channel. So far no practical uses, but the article mentions a few intriguing possibilities!"

Adieu, NanoCAD list?

from the roads-not-taken? dept.

NanoCAD represented a significant initiative to promote open development of software for molecular nanotechnology. Will Ware, the maintainer of the NanoCAD list, is now planning to discontinue the list, given the lack of traffic and his need to change ISPs.

This raises the question, is there enough interest to continue initiatives to develop software, and associated standards and licensing, that could be freely and openly shared by those interested in MNT?

New clues to the genetic basis of ageing

from the be-careful-when-choosing-grandparents dept.
Andrew writes "This item from the Proceedings of the National Academy of Sciences from New Scientist: Annibale Puca and his team of researchers at the Howard Hughes Medical Institute (HHMI) have used genetic linkage analysis to show a 95% probability that a particular region on chromosone four correlates to long lifespan in humans. Importantly this region appears to have a strong influence on the rate of ageing. Read about it at: http://www.newscientist.com/news/news.jsp?id=ns999 91201"

According to an HHMI press release, "By comparing the DNA of siblings who are extremely long-lived, researchers believe they have found a region on chromosome 4 that may hold an important clue to understanding human longevity. According to the researchers, their finding is "highly suggestive" that somewhere in the hundreds of genes in that region of chromosome 4 is a gene or genes whose subtle modifications can give a person a better chance of living well beyond the average life expectancy."

Canada to create national center for nanotechnology

from the World-Watch dept.
With funding provided by the Canadian federal and the Alberta provincial governments, Canada will create a National Research Centre facility devoted to nanotechnology. The new NRC facility will be located at the University of Alberta in the provincial capital of Edmonton. Funding for the center will total about $CN 100 million, with roughly equal contributions from federal and provincial sources.

National and political motivations played a large role in the decision to establish the center in Alberta, which does not currently have a NRC facility. However, the University of Alberta is a good choice: UA already has made nanotechnology research a priority, and has 60 faculty members with expertise in the area — more than any other Canadian university.

Special Issue of Scientific American devoted to nanotech

from the The-vision-thing dept.
Nanotechnology is the focus of a special issue of Scientific American (September 2001). About half of the articles are available online, including a relatively brief piece by Eric Drexler ("Machine Phase Nanotechnology").

However, the tenor of the other articles is, in general, either skeptical or openly hostile to the concept of machine phase chemistry or mechanosynthesis, as well as advanced applications, as pointed out by Sander Olson, who writes "Scientific American's latest issue has the cover story on nanotechnology. Although the issue has an article from Mr. Drexler ("Machine Phase Nanotechnology"), most of the articles are highly critical of Drexlerian nanotechnology concepts. In one article, Gary Stix claims that Drexler's contribution to nanotechnology will be akin to Star Trek's — a fantasy that will nevertheless encourage people to enter the field. In another article, George Whitesides argues that "The charm of the assembler is illusory: it is more appealing as metaphor than as reality, and less the solution of a problem than the hope for a miracle." "

U.S. will review nanotech efforts

from the self-replicating-bureaucracies dept.
According to an extensive article on the SmallTimes website ("U.S. studies its nanotech plan to make sure itís on right path", by Jeff Karoub, 22 August 2001), the U.S. government has launched two projects to review its nanotechnology research and development efforts. Two committees organized by the National Research Council (NRC), an independent advisory body under the National Academy of Sciences (NAS) serving the government, will conduct the reviews.

The first will be a Review of the National Nanotechnology Initiative sponsored by the U.S. National Science Foundation (NSF), which will take about 1 year. An interim report is due in October 2001 and a final report in May 2002. Information on the project, including scope, committee membership, and committee meetings is available on the NAS web site.

The second review will involve officials from the U.S. Air Force and Defense Department, and will examine the role of micro- and nanotechnologies in the military and how they could improve weapons systems and capabilities. The NRC released a report in June 2001 that recommended the U.S. Army embrace advancements in biotechnology.

IBM researchers create nanotube-based NOT gate

from the circuit-logic dept.
Researchers at IBM have created and demonstrated the world's first logic-performing computer circuit within a single molecule, according to an IBM press release. The device, based on a carbon nanotube, functions as a voltage inverter and thus acts as a NOT gate — one of the three fundamental binary logic circuits that are the basis for digital computers. They encoded the entire inverter logic function along the length of a single carbon nanotube, forming the world's first single-molecule logic circuit.

The achievement was announced on 26 August 2001 at at the 222nd National Meeting of the American Chemical Society (ACS) held in Chicago. The full research paper describing the device is available in the online ACS journal, Nano Letters ("Carbon Nanotube Inter- and Intramolecular Logic Gates")

In April 2001, the same IBM team became the first to develop a technique to produce arrays of carbon nanotube transistors, bypassing the need to separate metallic and semiconducting nanotubes. The team used these nanotube transistors to make the NOT circuit.

Computer program learns language in artificial childhood

An Anonymous Coward points out this item from the Reuters news agency on CNN, which deals with an AI langugage-learning research project in Israel, aimed at teaching a computer to use language the same way a human child does. Appropriately for this year of 2001, the program is name HAL. Read about it at:

NSF will sponsor nanoscience symposium

from the wonk-session dept.
The U.S. National Science Foundation (NSF) will is sponsoring a day-long symposium titled "Small Wonders: Exploring the Vast Potential of Nanoscience" on Thursday, 13 September 2001 at the Ronald Reagan Building & International Trade Center, Large Amphitheater, in Washington D.C., from 8:30 a.m. – 5:30 p.m. A Program, Speakers & Exhibitors List is available online. Featured speakers will include NSF Director Rita Colwell, Senator Joseph Lieberman, Richard Smalley of Rice University, and Chad Mirkin of NWU Institute of Nanotechnology.

The event is open to the public, and apparently is free (no registration fee is mentioned). An invitation form is available as an Adobe Acrobat PDF. Attendees are requested to respond to [email protected] by 7 Spetember 2001.
