Scientists unveil 'clay' robots that will shape our world. TINY robots that
can turn into any shape - from a replica human to a banana to a mobile
phone - are being developed by scientists in the United States. The new
science of claytronics, which will use nanotechnology to create tiny robots
called catoms, should enable three-dimensional copies of people to be
"faxed" around the world for virtual meetings. A doctor could also consult
with a patient over the phone, even taking their pulse by holding the wrist
of the claytronic replica, reports New Scientist.

Nano World: Nano for stem-cell research. Cutting-edge nanotechnology is
beginning to help advance the equally pioneering field of stem-cell
research, with devices that can precisely control stem cells and provide
self-assembling biodegradable scaffolds and magnetic tracking systems,
experts told UPI's Nano World. "Nanotechnology might show people once and
for all that you really can help regenerate organs with stem-cell biology
and help people walk again, help people after heart attacks, help people
after stroke," said John Kessler, a neurologist at Northwestern University
in Evanston, Ill. (World Peace Herald 6/13/05)

Quantum dots prove to be a faster, more sensitive method for detecting
respiratory viral infections. In what may be one of the first medical uses
of nanotechnology, a chemist and a doctor who specializes in infectious
childhood diseases have joined forces to create an early detection method
for a respiratory virus that is the most common cause of hospitalization
among children under five. (Exploration 6/9/05)

MIT's Nanoprinter Could Mass-produce Nano-devices. Just as the printing
press revolutionized the creation of reading matter, a "nano-printing"
technique developed at MIT could enable the mass production of nano-devices
currently built one at a time. The most immediate candidate for this
innovation is the DNA microarray, a nano-device used to diagnose and
understand genetic illnesses such as Alzheimer's, viral illnesses such as
AIDS, and certain types of cancer. The ability to mass produce these complex
devices would make DNA analysis as common and inexpensive as blood testing,
and thus greatly accelerate efforts to discover the origins of disease.

Nanoparticles transport cancer-killing drug into tumor cells to increase
efficacy, lower drug toxicity in mice. U-M scientists use folic acid as bait
to get methotrexate inside tumor cells. University of Michigan scientists
have created the nanotechnology equivalent of a Trojan horse to smuggle a
powerful chemotherapeutic drug inside tumor cells - increasing the drug's
cancer-killing activity and reducing its toxic side effects..."This is the
first study to demonstrate a nanoparticle-targeted drug actually leaving the
bloodstream, being concentrated in cancer cells, and having a biological
effect on the animal's tumor," says James R. Baker Jr., M.D., the Ruth Dow
Doan Professor of Biologic Nanotechnology at the University of Michigan, who
directed the study. (UMHS 6/15/05)

Commissioner responds to children's nano questions. EU Science and Research
Commissioner Janez Potocnik answered questions from children on
nanotechnology when he visited the nanoTruck in Brussels on 15 June. A
German initiative, the nanoTruck is a mobile science theme park exhibiting
some of the latest science and technology at the nano dimension in a variety
of disciplines. Inside the truck are magnetic fluids, measuring instruments
that make atoms visible, and scratch-proof coatings for cars. The organizers
encourage visitors try out the exhibits themselves, making it an ideal place
to introduce the younger generation to the wonders of nanoscience and
nanotechnology.

Good news about saliva or "spit". Dr. Wong, who also leads UCLA's Dental
Research Institute, described the latest in saliva diagnostic research to
attendees at the American Dental Association's National Media Conference,
held here today. "We have developed highly specific, nanotechnology-based
biosensors (ultra tiny machines that read the simplest cell structure),
which will permit the detection of disease-bearing biomarkers in saliva,"
said Dr. Wong. Scientists have long recognized that saliva contains the full
complement of proteins, hormones, antibodies and other molecular substances
frequently measured in standard blood tests to monitor health and disease,
he explained. (myDNA 6/9/05)

NCL to go into labs with 'Golden Triangle' for cancer trials. EIGHT months
after raising hopes with their cutting edge 'Golden Triangle' technology for
fighting cancer sans chemotherapy, nanoscientists at the National Chemical
Laboratory (NCL) are gearing up for the technology's first in-vitro tests.
Murali Sastry, head, Nanoscience Group at NCL, said the in-vitro
(laboratory) tests would be conducted on cancerous cells in a month's time
at the Tata's Advanced Centre for Treatment, Research and Education in
Cancer (ACTREC) in Navi Mumbai...The trials are being conducted to establish
the toxicity of the gold nano-particles. ''While gold is inherently
non-toxic, we have to see exactly where the nano-sized triangles go when
introduced into the cancerous area. We have kept a two-year window to see if
we can get into clinical trials on humans.''

World's most precise "hard x-ray" nanoprobe activated. Marking a major step
forward in using x-rays to study extremely small structures and phenomena,
the world's first "hard x-ray" nanoprobe beamline was activated on March 15,
2005. The unique nanoprobe is one of the featured instruments at the new
Center for Nanoscale Materials (CNM), a U.S. Department of Energy user
research facility located at Argonne National Laboratory, about 25 miles
west of Chicago. CNM researchers expect to soon be using the x-ray nanoprobe
to study individual atoms, molecules, and the unique physical interactions
that occur at the nanoscale, where features are measured in nanometers, or
billionths of a meter (a nanometer is 70,000 times smaller than the width of
a human hair). (Nanoapex 5/30/05)

Thin films of silicon nanoparticles roll into flexible nanotubes. By
depositing nanoparticles onto a charged surface, researchers at the
University of Illinois at Urbana-Champaign have crafted nanotubes from
silicon that are flexible and nearly as soft as rubber. "Resembling
miniature scrolls, the nanotubes could prove useful as catalysts, guided
laser cavities and nanorobots," said Sahraoui Chaieb, a professor of
mechanical and industrial engineering at Illinois and a researcher at the
Beckman Institute for Advanced Science and Technology. (Eurekalert 6/14/05)

Nanotechnology's Environmental, Health, and Safety Risks Can Be Addressed
Responsibly Today. Stakeholders ranging from corporations to start-ups to
protest groups are concerned about the environmental, health, and safety
(EHS) risks of nanoparticles -- the prospect that tiny, engineered particles
of matter might harm workers, consumers or the environment. While such EHS
risks do exist, they can be appropriately addressed today using
well-established risk management techniques, according to a new report from
Lux Research entitled "A Prudent Approach to Nanotech Environmental, Health,
and Safety Risks." (Yahoo 6/15/05)

When Nanopants Attack. On a chilly Chicago afternoon in early May,
environmental activists sauntered into the Eddie Bauer store on Michigan
Avenue, headed to the broad storefront windows opening out on the
Magnificent Mile. Activists hoped to lay bare growing allegations of the
toxic dangers of nanotechnology. The demonstrators bore the message in
slogans painted on their bodies, proclaiming "Eddie Bauer hazard" and
"Expose the truth about nanotech," among other things, in light of the
clothing company's embrace of nanotech in its recent line of stain-resistant
"nanopants." (Wired 6/16/05)

Brush up on your nanotechnology. The world's smallest brushes, with bristles
more than a thousand times finer than a human hair, have been created by
researchers in the US. The brushes can be used for sweeping up nano-dust,
painting microstructures and even cleaning up pollutants in water. The
bristles' secret is carbon nanotubes, tiny straw-like molecules just 30
billionths of a metre across. They are incredibly tough and yet flexible
enough that they will yield when pushed from the side. The researchers
behind the brushes were led from Rensselaer Polytechnic Institute in Troy,
New York. Their work is reported in the journal Nature Materials. (BBC

'Emerging Sectors' maps new type of summer camp. What will your kids tell
classmates they did this summer? Attend soccer camp? Swim at the pool? Study
nanotechnology? Instructors at Oakland Schools hope the response will be the
latter as the school system is modeling much of its summer enrichment
programs after the county's Emerging Sectors initiative. The curriculum
received praise from government officials and industry leaders, who say
getting technology training into youngsters' hands is essential in creating
tomorrow's high-skilled workforce.

Does 10% = Halfway? To "maximize the potential and minimize the risks" of
nanotechnology, DuPont CEO Chad Holliday and Environmental Defense (ED)
President Fred Krupp are calling for "increased risk research, improved
regulatory oversight, proactive corporate management standards, and broad
stakeholder engagement." Given potential liability and market risks,
industry, universities, government and public interest groups should
collaborate to determine what testing is necessary for new nanoproducts.
Businesses then should conduct the needed testing before new products enter
commercial use. . . A collaborative effort could set interim standards for
nanotechnology around the world while regulations are under development.
