Molecules get More Classical at High Pressures. A new study of molecules
being squeezed in a diamond anvil cell shows that as the pressure goes up,
the force between atoms in a two-atom molecule behaves more and more like
the classic Hooke's law, according to which the force between two objects
connected by an elastic spring is proportional to the contraction or
extension of the spring.

Nano World: Gold nano vs. Alzheimer's. Gold particles only nanometers or
billionths of a meter wide together with extremely weak microwaves can
dissolve the abnormal protein clumps linked with Alzheimer's disease and
potentially those linked with other degenerative illnesses as well, experts
told UPI's Nano World. (Physorg 1.20.06)

Cell-Based Nano Machine Breaks Nano-Record. Researchers have known for some
time that a long, fibrous coil grown by a single-cell protozoan is, gram for
gram, more powerful than a car engine. Now, researchers at Whitehead
Institute-together with colleagues at MIT, Marine Biological Laboratory in
Woods Hole, MA, and University of Illinois, Chicago-have found that this
coil is far stronger than previously thought. In addition, the researchers
have discovered clues into the mechanism behind this microscopic powerhouse.

Atom Hauler: Molecular rig snags multi-atom loads. A molecule with a knack
for picking up and delivering atoms may prove a useful tool for atomic-scale
construction. Scientists in France and Germany who created and tested the
molecule say that it and similar custom-made structures might aid tasks such
as building molecular-scale circuitry, depositing arrays of atom clusters
with special optical or magnetic properties, and cleaning up debris on
nanoconstruction sites.

Brookhaven Scientists Study Liquid "Nanodrops". Scientists from the U.S.
Department of Energy's Brookhaven National Laboratory have discovered that
drops of liquid with thicknesses of just a few billionths of a meter, or
nanometers, are shaped differently than macroscopic liquid drops. Their
results, published in the February 9, 2006, online edition of Physical
Review Letters, help elucidate the behavior of nanoscale amounts of liquid
and, as a result, may help advance several developing nanotechnologies.

Cornell scientists build 'nano-keys' to bind cell receptors and trigger
allergic reactions. Cornell University researchers have fabricated a set of
"nano-keys" on the same scale as molecules to interact with receptors on
cell membranes and trigger larger-scale responses within cells, such as the
release of histamines in an allergic response. How cell membranes control
cellular function has long been studied but with few results. However,
nanotechnology now gives researchers new tools to better understand the role
of cell membranes in activating responses within cells. (Cornell 2.16.06)

Water Wire. It flows in rivulets, puddles in depressions, falls from the
sky; you can even buy it at Costco--three-dimensional, "bulk" water is
everywhere. Now, in the 28 October PRL, researchers report a new
configuration of a nearly one-dimensional column of water. Although similar
forms of water are common in biology, they are rarely seen in the lab, so
this liquid "nanowire" may soon reveal important properties of water at the
molecular scale. (Physical Review Focus 11.11.05)

Nanotechnology used to combat freezing feet. Attention Canadians. If you
just trudged in from a blizzard, you may want to take a look at ToastyFeet.
The company sells shoe insoles that can keep feet warm despite snow and ice.
You can stand on a block of dry ice, chilling at minus 106 Fahrenheit, and
your feet will still be 72 degrees. (CNET 2.15.06)

Add Some Atoms, Squeeze Some Buckyballs, Flip a Switch. The First Direct
Observation of the Jahn-Teller Distortion in Single Molecules. "Degeneracy"
is one of those words that mean something quite different when used by a
preacher, a chess player, an astrophysicist, or a mathematician.* To
chemists and physicists, degeneracy describes a state in which an electron
could potentially occupy either of two orbital paths around a molecule, both
of which have the same energy level. (Berkeley Lab 11.29.05)

DNA-Wrapped Carbon Nanotubes Could Target Specific DNA Sequences.
Researchers at the University of Illinois at Urbana-Champaign who recently
reported that DNA-wrapped carbon nanotubes could serve as sensors in living
cells now say the tiny tubes can be used to target specific DNA sequences.
Potential applications for the new sensors range from rapid detection of
hazardous biological agents to simpler and more efficient forensic
identification. (azonano 2.23.06)

Could Nanoparticles be Designed to Become Potent Antioxidants? Research at
the Salk Institute for Biological Studies and Columbia University now shows
that nanoparticles composed of cerium oxide or yttrium oxide protect nerve
cells from oxidative stress and that the neuroprotection is independent of
particle size. As one of the researchers, Professor Dave R. Schubert, head
of the Cellular Neurobiology Laboratory at Salk, told Nanowerk: "While there
has been a great deal of interest in using nanoparticles as drug delivery
vehicles, there has been much less interest in exploring the alternative
that they can be engineered to have direct beneficial biological effects."

Nano World: New aimed nanoparticles. A new method to develop collections of
nanoparticles that each seek out different cell types could help scientists
to better spot tumors before they grow or to deliver medicines to precise
targets, experts told UPI's Nano World. Interventional radiologist Ralph
Weissleder at Harvard Medical School and his colleagues are developing
nanoparticles that can emit either magnetic or optical signals. The hope is
to coat these nanoparticles with compounds that help guide their way toward
specific cells. Such coated nanoparticles could then single out tumor cells
to help physicians detect where they are in the body, even if they are few
in number and otherwise unnoticeable. (UPI 12.6.05)

Gold Nanoparticle-Virus Networks Work as Intracellular Sensors and Targeting
Agents. Researchers at The University of Texas M. D. Anderson Cancer Center
report that they have created a way for viral and gold particles to
"directly assemble" and potentially seek out and treat disease where it
resides in the body. Their study, published in the Proceedings of the
National Academy of Science USA, demonstrates how to use biologically
compatible materials to fabricate a "nanoshuttle" that can be harnessed to
viral particles to precisely home to disease wherever it hides.

Computer Simulation Shows Buckyballs Deform DNA. Soccer-ball-shaped
"buckyballs" are the most famous players on the nanoscale field, presenting
tantalizing prospects of revolutionizing medicine and the computer industry.
Since their discovery in 1985, engineers and scientists have been exploring
the properties of these molecules for a wide range of applications and
innovations. But could these microscopic spheres represent a potential
environmental hazard? A new study published in December 2005 in Biophysical
Journal raises a red flag regarding the safety of buckyballs when dissolved
in water. It reports the results of a detailed computer simulation that
finds buckyballs bind to the spirals in DNA molecules in an aqueous
environment, causing the DNA to deform, potentially interfering with its
biological functions and possibly causing long-term negative side effects in
people and other living organisms. (Medical News Today 12.8.05)

Military Nanotech Spending Proves Difficult to Tap. Abstract: U.S.
Department of Defense has funded $195 million in small business nanotech
grants since 2002, but only 6% made it past a first phase. - With threats
to the U.S. increasingly coming from terrorist organizations, rogue nations,
and insurgencies, the military is driving a major effort to improve its
capabilities - making it one of the best prospective buyers for applications
of nanotechnology. But companies large and small that supply these nanotech
solutions are failing to exploit the military market effectively because of
mismatched development strategies, according to a new report from Lux
Research entitled "Setting Supplier Strategies for Military Nanotech
Applications." (Nanotechnology Now 2.27.06)
