Methodist Neurosurgeon Makes Quantum Leap on Nano-Level. A neurosurgeon at the 
Methodist Neurological Institute (NI) is the first to use an enzyme-driven 
technique to label nanotubes with quantum dots, giving scientists a better way 
to see single-walled carbon nanotubes...Dr. David Baskin, neurosurgeon at the 
Methodist NI, and his colleagues published these research findings in the March 
2006 issue of BioTechniques. (Physorg 2.22.06) 

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) http://www.physorg.com/news10099.html

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. (newswise 12.5.05) 

Navy, UH team up to detect biological agents, land mines. NSF grant establishes 
nanomagnetics research program in collaboration with Naval Research Labs. 
Detecting biological agents, developing land mine discovery techniques and 
improving computer memory durability are among the projects in which some 
University of Houston engineering students will be involved through the National
Science Foundation-Navy Civilian Service Fellowship Program. (Eurekalert 

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. (Brookhaven 2.17.06) 

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) http://focus.aps.org/story/v16/st15

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.

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. (nanotechwire 2.12.06)

Nano-Armor: Protecting the Soldiers of Tomorrow. An Israeli company has recently
tested one of the most shock-resistant materials known to man. Five times 
stronger than steel and at least twice as strong as any impact-resistant 
material currently in use as protective gear, the new nano-based material is on 
its way to becoming the armor of the future. (Physorg 12.10.05) 

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

Kids learn nanotechnology at Nanoworld. Elementary school children across the 
United States have been learning about incomprehensibly tiny things in an 
exhibition created by Cornell University. The children make the discoveries 
while walking through and playing with very large and colorful things in the 
traveling science museum exhibition created by the Cornell Nanobiotechnology 
Center. (Upi 2.20.06)

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)
