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)

Scientists Fret over nanotech breakthrough. A breakthrough in
nanotechnology has enabled doctors accurately to measure the levels of
crucial chemicals in living brain cells in real time and at the level of
a single cell. Scientists at Stanford University and the Carnegie
Institution's Department of Plant Biology claim to be the first
successfully to apply genetic nanotechnology using molecular sensors to
view changes in brain chemical levels. (Computing 5/31/05)

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)

UCI scientists use nanotechnology to create world's fastest method for
transmitting information in cell phones and computers. UC Irvine
scientists in The Henry Samueli School of Engineering have demonstrated
for the first time that carbon nanotubes can route electrical signals on
a chip faster than traditional copper or aluminum wires, at speeds of up
to 10 GHz. The breakthrough could lead to faster and more efficient
computers, and improved wireless network and cellular phone systems,
adding to the growing enthusiasm about nanotechnology's revolutionary
potential. (UCI 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. (Sciencedaily 6/9/05)

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.

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).

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

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."

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 6/12/05)

'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. (CRN blog 6/15/05)
