<DIV><FONT face=Arial size=2>'Nanorust' Cleans Arsenic From Drinking Water. The
discovery of unexpected magnetic interactions between ultrasmall specks of rust
is leading scientists at Rice University's Center for Biological and
Environmental Nanotechnology (CBEN) to develop a revolutionary, low-cost
technology for cleaning arsenic from drinking water. The technology holds
promise for millions of people in India, Bangladesh and other developing
countries where thousands of cases of arsenic poisoning each year are linked to
poisoned wells. The new technique is described in the Nov. 10 issue of Science
magazine.(Playfuls 11.11.06) <A

<DIV><FONT face=Arial size=2>Legos give kids a leg up on nanotechnology. The
U.S. Patent Office might want to hear about this: John Hurd and a team of
researchers have built a "nanoprobe" he says can clean clogged arteries. "The
nanoprobe swims through the arteries and pushes out all the cholesterol and
fat," explained the 9-year-old inventor. There is a caveat. The machine is only
in the minds of the pint-sized designers who have spent eight weeks studying
nanotechnology - the science of making super-small machines - while crafting
robots out of Legos. The Crestwood Elementary School fourth-grader is among more

Researchers have made a 'DNA machine' from a single molecule that detects a
virus by reading its genome, and then produces an alarm signal, in the form of a

<DIV><FONT face=Arial size=2>Nanoparticle Shows Promise In Reducing Radiation
Side Effects. With the help of tiny, transparent zebrafish embryos, researchers
at the Kimmel Cancer Center at Thomas Jefferson University and Jefferson Medical
College are hoping to prove that a microscopic nanoparticle can be part of a
“new class of radioprotective agents” that help protect normal tissue from
radiation damage just as well as standard drugs. Reporting November 7, 2006 at
the annual meeting of the American Society for Therapeutic Radiology and
Oncology in Philadelphia, they show that the nanoparticle, DF-1 – a soccer
ball-shaped, hollow, carbon-based structure known as a fullerene – is as good as
two other antioxidant drugs and the FDA-approved drug, Amifostine in fending off
radiation damage from normal tissue. (Sciencedaily 11.10.06) <A

nanocrystals mimic proteins. Crystalline nanoparticles of cadmium telluride, a

how it occurs through a combination of interactive forces between the

<DIV><FONT face=Arial size=2>Penn researcher shows that DNA gets kinky easily at
the nanoscale. Scientists have answered a long-standing molecular stumper
regarding DNA: How can parts of such a rigid molecule bend and coil without
requiring large amounts of force? According to a team of researchers from the
United States and the Netherlands, led by a physicist from the University of
Pennsylvania, DNA is much more flexible than previously believed when examined
over extremely small lengths. They used a technique called atomic force
microscopy to determine the amount of energy necessary to bend DNA over
nano-size lengths (about a million times smaller than a printed letter). (U of

Argonne National Laboratory scientists in collaboration with Xradia have created
a new X-ray microscope technique capable of observing molecular-scale features,
measuring less than a nanometer in height. Combining x-ray reflection together
with high resolution x-ray microscopy, scientists can now study interactions at
the nanometer-scale which often can exhibit different properties and lead to new
insights. Improving our understanding of interactions at the nanoscale holds
promise to help us cure the sick, protect our environment and make us more
secure. (Eurekalert 11.9.06) <A

<DIV><FONT face=Arial size=2>Carbon Nanotubes You Can Live With. Carbon
nanotubes, or CNTs, are hollow wires of pure carbon about 50,000 times narrower
than the finest human hair but stronger than steel. CNTs have enormous potential
in a variety of biological applications, including medical diagnostics and
treatments. There's a problem, however, and until now it has been what
technologists call a "stopper." For reasons not entirely known, CNTs are
cytotoxic — contact with them kills cells. This is one stopper that may have
been solved. A team of researchers with Berkeley Lab, the University of
California at Berkeley, and the Howard Hughes Medical Institute (HHMI) have
developed a means of making CNTs biocompatible. (Science Berkeley Lab 8.26.06)
