Ralph Merkle, Foresight Vice President for Technology Assessment and Principal Fellow at Zyvex Corporation, will be speaking at the following upcoming events:

The Business of Nanotechnology

Brent Magnan writes "Nanotechnology, or any newly emerging technology, is sure to change the way we live our lives. For those who want to be involved with technology, are there other ways to become part of it other than going through some kind of science degree? I'm currently in first year Engineering but want to go into Business (bachelor of commerce). Is switching faculties a huge mistake if I want to be involved with technology? Or are there lots of promising opportunities for a business student looking to be active in cutting edge technology? Please e-mail me with any suggestions or comments: send to: [email protected]"

Method of fluorinating carbon nanotubes developed

Vik writes "Rice University in cooperation with the Russian Academy of Science develop a way to add fluorine to nanotubes. This gives a handle to which functional groups can be attached with obvious repercussions. The process involves temperatures of 500C and pressures of 60,000 ATM. Press release from Rice is here."

Patrick Underwood submitted an article from Space Daily that provides some additional coverage of this annoucement.

Japanese Science & Technology Minister advocates reforms to boost nanotech

from the World-Watch dept.
The Asahi Shimbun in Japan ran an interview Koji Omi, Japanese State Minister in Charge of Science and Technology Policy ("Koji Omi: Unite nanotechnology with biotechnology", 8 April 2002), about the government's future strategy and outlook on the subject of nanotechnology. Some interesting comments by Mr. Omi:

Young nanotechnologists reach finals of ExploraVision competition

from the You-go,-girls! dept.
According to an article in the Tri-Valley Herald ("Students in finals of science competition", by Rebecca Emmerich, 20 March 2002), a local newspaper for the city of Dublin, California, a team of four fifth-grade students at the Quarry Lane School in Dublin have been named regional winners in the Toshiba/National Science Teachers Association ExploraVision competition. Their entry was a conceptual design for a "Nano Snippit-bot", a medical nanorobot that would operate in swarms to cut off the small blood vessels supplying cancer tumors. Their entry was one of only 24 selected from among those submitted by 4200 teams comprising 13,000 students from the United States and Canada to advance to the final round of the competition.

Two of the ten-year-olds on the Quarry Lane School nano-design team, Alejandra Dean and Nicole Rumore, have shown a strong interest in nanomedical robotics. In 2000, they and two other third-grade students at the Dorris Eaton School in Walnut Creek entered the design for a "Nano FatBuster" to fight atherosclerosis and heart disease; their visit with Foresight President Chris Peterson to gather information for the project was described in Foresight Update #42 (September 2000). The Nano FatBuster design also fared well: Out of 12,000 contestants, the quartet from Dorris Eaton School received an Honorable Mention Award. Only 2,000 of those were awarded.

Foresight applauds the dedication of Ms. Dean and Ms. Rumore, and wishes them and their team the best of luck in the final round of this yearís ExploraVision competition.

Texas foundation seeks to fund nanotechnology research

from the Institutional-innovation dept.
According to an article in the Houston Business Journal ("Nanotech funding foundation to be established in Bayou City", by Jennifer Darwin, 12 April 2002), "A unique endeavor is under way to fund nanotechnology research in Texas, and help turn the Lone Star State into the worldwide center for nanotechnology activity. NanoTex is being established as a foundation designed to fund nanotech research at Texas-based institutions. The Houston-based organization is still in the early launch phase, so its legal structure is not complete and fund-raising has not yet started."

"We truly have an opportunity in Texas to create something that would be the Silicon Valley of the 21st century," says Conrad Masterson, who developed the concept. "It's an area where we have a unique leadership advantage worldwide."

Researchers learn from natural ion channels to design new ones

from the Natural-Nanomachines dept.
An article in Science News ("Channel Surfing: Atomic-resolution snapshots illuminate cellular pores that control ion flow", by John Travis, 9 March 2002) describes the work of researchers who have been uncovering the details of the structure and function of ion channels — protein complexes that act as natural, highly-specific atom sorting devices.

In addition to revealing the operating principles of natural sorters, the research has provided insights into the design of de novo sorter designs, as shown in another online article on the Nature Science Update website ("New channel built: Chemists copy from cells to make a tunnel for salt", by Philip Ball, 13 March 2002), which describes work by George Gokel and colleagues at Washington University in St Louis, Missouri, who created a synthetic peptide-based channel can be opened and closed by applying a voltage.

Additional details of research into ion channels and other types of natural atom sorters can be found in Nanodot posts from 17 January 2002 and 2 November 2001.

Open Source GM Crops?

Gina Miller writes "Genetically-modified crops spotlight issues of safety, openness, and intellectual property that will become even more important with molecular nanotechnology. Some similar concerns are reflected in the Foresight Guidelines on Molecular Nanotechnology.

UK report says gene crops could create superweed. Cross-pollination of seeds spilt during harvest allowed three varieties of genetically modified rapeseed plants to exchange herbicide resistance genes, creating a "superweed" resistant to all three herbicides. To avoid these superweeds that would be difficult to eliminate, the recommendation is that only one variety of herbicide resistance be used in genetically modified plants.

Panel Urges U.S. to Tighten Approval of Gene-Altered Crops. The caution recommended by the UK panel was reflected by a panel convened by the US National Academy of Sciences. Noting that biotechnology companies are developing new plants containing combinations of genes, or genes that cause the plant to produce industrial chemicals or other exotic materials, the panel concluded that testing of genetically altered plants should be made "significantly more transparent and rigorous." The panel's conclusion implies that public access to data should take precedence over the ability of companies to keep data confidential.

Can a company still profit from data it releases to the public? Swiss Firm Unveils Plan for Sharing Rice Genome One company poised to publish a "draft" (not completely finished) sequence for the genome of a variety of rice announced a compromise in which the company 'would freely share the information with researchers, but keep the right to license and patent commercial developments'. Other companies preparing sequences of other varieties of rice have promised completely free access to the information. How access to scientific information developed by for-profit entities will be handled is clearly an issue very much in flux: from open source software to biotechnology and gene patents. What will be the trade-offs as nanotechnology matures?"

Nanotube-laced epoxy: three times harder, far bett

brianwang writes "The longstanding promise of superfortified heat-conducting materials has become a reality. University of Pennsylvania scientists have determined that adding a relatively small number of carbon nanotubes to epoxy yields a compound three-and-a-half times as hard and far better at heat conductance than the product found in hardware stores. The researchers report their successful tinkering with the commonplace adhesive in the April 15 issue of the journal Applied Physics Letters. Led by Penn physicist Alan T. "Charlie" Johnson, the team created a composite of 95 to 99 percent common epoxy mixed with 1 to 5 percent carbon nanotubes, filaments of carbon less than one-ten-thousandth the width of a human hair. "These findings add considerably to carbon nanotubesí luster as possible additives to a variety of materials," said Johnson, an associate professor of physics and astronomy at Penn. "In addition to adhesives such as epoxy, we are looking at nanotube-based greases that might be used to carry heat away from electronic chips." Johnsonís group determined that epoxy doped with nanotubes showed a 125 percent increase in thermal conductivity at room temperature. "This is the first published report of enhanced thermal conductivity in a material owing to the addition of carbon nanotubes and the first demonstration of simultaneous thermal and mechanical enhancement of a real-world material," Johnson said. Epoxy is an attractive target for fortification with carbon nanotubes, Johnson said, because itís relatively easy to mix the minuscule filaments into it, and there are clear industrial benefits in a harder, better-conducting epoxy. Other scientists have attempted to fortify epoxy with carbon nanotubes, but Johnsonís group succeeded in dispersing the nanotubes more evenly. http://www.eurekalert.org/pub_releases/2002-04/uop -net041502.php"
