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

Researchers have known for some time that a long, fibrous coil grown by a

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

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) <A

<DIV><FONT face=Arial size=2>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) <A

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)<BR><A
