Roland Piquepaille writes "NASA is testing a shape-shifting robot called "TETwalker" for tetrahedral walker, because it looks like a flexible pyramid. It has been tested in the lab and at the McMurdo station in Antarctica to test it under conditions more like those on Mars. Now, it is on the way to be — really — miniaturized by using micro- and nano-electro-mechanical systems. These robots will eventually join together to form "autonomous nanotechnology swarms" (ANTS). When it's done, in about thirty years, these nanotech swarms will "alter their shape to flow over rocky terrain or to create useful structures like communications antennae and solar sails." So in 2034, nanotechnology will land on Mars. Read more for other details and references about the TETwalker and the ANTS project."

bhelfrich writes "Nano-Hive version 1.1.0 for win32-x86 is now available for download. *nix distros will be made available in the coming weeks.

This release adds support for running multiple, multi-threaded simulations simultaneously, each able to access multiple Physical Interaction plugins.

We've also added new plugins.

• MPQC_SClib – This plugin encapsulates the functionality of the Scientific Computing Toolkit (SC) used by the Massively Parallel Quantum Chemistry Program (MPQC).
• OpenBabelImportExport – This Data Import/Export plugin adds the ability to read and write many new file types by encapsulating the OpenBabel library.
• SocketsControl – Control Nano-Hive via a TCP socket with this Simulation Control plugin.
• BondCalculator – This Physical Interaction plugin discovers molecules in the simulation space and specifies bonds to describe them.
• BasicCellTraverser – This Entity Traversal plugin divides the simulation space up into sub-cells for multi-threaded calculation.

Also included in this release is an alpha version of the HiveKeeper Graphical User Interface for Nano-Hive (http://www.nano-hive.org/hivekeeper/). The capabilities of the alpha version includes visualization of the molecular structures even while the simulation is running.

Molecular Manufacturing: Step by Step

Advanced nanotechnology — molecular manufacturing — will bring benefits and risks, both on an unprecedented scale. A new paper published by the Center for Responsible Nanotechnology suggests that development of molecular manufacturing can be an incremental process from today's capabilities, and may not be as distant as many believe.

"Molecular manufacturing has always had great promise, but as a single challenge, it has seemed intimidating. Breaking the problem down into stages shows that it can be achieved step by step," says Chris Phoenix, CRN?s Director of Research and author of the paper, "Developing Molecular Manufacturing."

Keven Kelleher from TheStreet.com has a good piece here discussing nanohype. Tim Harper had an interesting comment regarding whether people "know the difference between a macrophage and a macromolecule?" Neither of these is strictly about nanotechnology but his question and the answers it might prompt would be illuminating.

Readers might offer better questions to determine "Is or is not someone nanoliterate?"

Roland Piquepaille writes "Researchers from the Lawrence Berkeley National Laboratory (LBL) have developed fluorescent and stable nano-probes which can stay inside a cell's nucleus for hours or even days. According to this LBL news release, this will help biologists to better understand nuclear processes that evolve slowly, such as DNA replication, genomic alterations, and cell cycle control. This research was partially based on previous investigations about quantum dots. Now, the researchers want to tailor their quantum dots, which emit different colors depending on their sizes, to check specific chemical reactions inside nuclei, such as how proteins help repair DNA after irradiation. Read more for other details and references and to see how a nano-sized probe is entering a cell's nucleus."

The Prime Minister's council working party predicts (registration required) that in 10 years, nanotechnology could have as much impact as the discovery of electricity or the development of the computer microchip.

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."

The AZoNano Online Journal of Nanotechnology

The Online Journal of Nanotechnology is based on a free access publishing model, coupled with what is believed to be a unique development in the field of scientific publishing — the distribution of journal revenue between the authors, peer reviewers and site operators.

The revenue received from the journal related advertising and sponsorship will be distributed according to the following general criteria: – Authors receive a revenue share of 50%, – Peer reviewers receive a revenue share of 20%, – The site administrators receive a revenue share of 30%, – This revenue share will apply throughout the online published life of the individual article or paper.

The Online Journal of Nanotechnology will publish high quality articles and papers on all aspects of nanotechnology and related scientific, social and ethical issues. All the contributions will be reviewed by a world class panel of founding editors who are experts in a wide spectrum of nanotechnology science.

Journal papers will benefit from being hosted on the AZoNano.com website and database platform as they will take advantage of existing search tools and be available to a monthly audience of over 130,000 visitor sessions. The unique AZoNano search tools also make it very easy for site visitors to locate nanotech information that relates directly to their research areas, applications and industrial sectors.

It would appear that Adrian Bower, a lecturer at the University of Bath, is promoting an open source project for a "Replicating Rapid-Prototyper" that can reproduce not only itself but other macroscale objects.

More on self-replication…

The World Peace Herald and the Meridian Institute are discussing on the problem of whether nanotechnology will reach the poor.

Given years of history with open source software we already know how to solve this problem. This is pointed out by Bryan Bruns, a sociologist with the Foresight Institute, who promotes better policies on intellectual property, including full publication of publicly-funded research in ways that are accessible and affordable.

This feeds into a complex development problem. In an ideal world developments paid for by the public should be available to the public. At the same time business will be disinclined to push those developments to the marketing stage without some exclusive rights on the market. How does one resolve this problem?

A group of physicists (Naumov, Bellaiche & Fu) at the Univ. of Arkansas are reporting in Nature the exploration of phase transformations in non-volatile ferroelectric memories composed of Pb(Zr,TI)O₃. They are finding that the minimum size of nanodiscs/nanorods able to retain a bistable state is of the order of 3.2 nm. That translates to 60×10¹² bits/sq. inch (7+ terabytes/sq. in).

Obviously there are a couple of problems here. The first would be how do you read or write a nanorod every 3.2 nm? Of course this may drive the need for improved nanowiring and/or nanomechanical head positioning. The second would be the claim regarding "low-temperature structural bistability". How low does the temperature actually need to be? If one needs a room full of refrigeration equipment to allow a nanoscale memory to retain its data then the applications may be somewhat limited. E.g. you aren't going to see it in an iPod.

At a news conference in Washington D.C. today a number of SIA leaders questioned the ability of the U.S. to retain its lead role in the semiconductor industry as it moves into nanoscale technologies. They called for a number of solutions including increased funding for the NSF of 7%/yr. In contrast, as reported by Thomas Freidman in the NY Times on Dec. 26, 2004, the proposed Bush-Republican 2005 budget specified a $100M cut to the NSF. (The actual budget request is open to debate as is seen here and here.) For comparison purposes the NSF budget is slightly less than $6B while the war in Iraq from March 2003 thru 2005 is estimated at $207B.

Clearly the industry leaders recognize that long term R&D support is required and because the financial markets do not seem to have worked out a model which could enable this they must turn to the government for support. It would seem that those involved in politics are not quite as able to connect the dots as one would hope. One could double funding for the NSF for 15 years for the cost of a war. The advancements in nanotechnology that such R&D could provide could so advance the quality of life of people in places such as Iraq that there would be significantly fewer incentives to become a terrorist or an insurgent. Two extremely simple problems — clean water and sufficient electricity — could be significantly dealt with through applications of nanotechnology in Iraq. Why is there no focus on these approaches to uplifting their population? �

Nature materials is reporting on the development of static "flash" memory based on antimony telluride "cells" that are flipped between amorphous and crystalline states. These cells may be able to be scaled to 10 nm. The architecture is very simple as it simply requires sensing the resistance of the cell to determine whether it is in a one or zero state. This is distinctly different from current DRAM memory cells which are based on the storage of electrons within a capacitor. Because the electrons leak out of the capacitor it is necessary to include electronics that restore the state of the memory on a continual basis.

Foresight Senior Associate Ramez Naam informs us that his book More Than Human has been released.

Here's a description of the book:
"More Than Human is about our growing power to alter our minds, bodies, and lifespans through technology. Over the last 5-10 years scientists and doctors have learned an incredible amount about how to enhance memory, improve physical performance, rewrite our genes, alter the rate of aging, and even how to connect our brains directly with computers and robots. This is not science fiction – this is the research happening in labs around the world right now, research that's restored sight to blind men and women, created mice that live to the age of 200 in "human years", and given the paralyzed the ability to control computers just by thinking about it."

For those who didn't notice it in several sources (here, here or here), IBM has announced external access to its Blue Gene supercomputer. It provides 5.7 Teraflops in a single rack. Obviously IBM has the ability to hook a large number of these together should they choose to do so. 175 racks gives you a petaflop.

Physorg.com is reporting that HP Labs in conjuction with Applied Physics A will be having an "invitation-only international nanotechnology symposium" on March 25. They intend to outline the HP combined strategy (fundamental scientific research into nanometer scale quantum effects; defect tolerant architectures for molecular components; and cost-effective fabrication methods) for implementing robust molecular electronics.

My only question is "When will we see the results?"
