MOLECULAR
FOUNDRY GROUNDBREAKING MARKS BERKELEY LAB'S LEAP
INTO THE NANOREVOLUTION
BERKELEY,
CA , USA. The term “Molecular Foundry” suggests a place where
objects are forged and new materials are
molded. Like the foundries of
the
industrial revolution, this new concept, on a
nanoscale, promises to
revolutionize
the way the world works. It begins at the Department
of
Energy’s
Lawrence Berkeley National Laboratory – ceremonially,
on Friday, Jan. 30).
That’s
when ground was turned for the official beginning
of construction
on
a six-story, $85 million, 94,500-square-foot research
building that
will
be one of the centerpieces of the DOE’s Nanoscale
Research Program.
Berkeley
Lab’s Molecular Foundry is one of five DOE research
centers to
be
constructed over the next few years.
“This
facility will assist scientists in reaching new
frontiers in the
study
of nanoscale research and its practical application,”
Secretary of
Energy
Spencer Abraham said. “It represents a beginning
of a revolution
in
science, opening up a broad array of innovation
in materials science,
biology,
medicine, technologies for environmental research
and national
security.
“Berkeley
is blessed with tremendous resources, such as
the national
supercomputing
center (NERSC), the Advanced Light Source, and
the
National
Center for Electron Microscopy,” he added. “All
will be
instrumental
in the revolution in science offered by the Molecular
Foundry.”
“Nanoscale
research will, in many respects, represent the
new building
blocks
for new technologies and applications across the
science and
industry
spectrum,” said Berkeley Lab Director Charles
Shank.
“Understanding
the properties of materials on the tiniest scale
will
have
an impact on everything, from medicine to manufacturing.”
Nanoscale
research enables scientists literally to build
novel
structures
atom by atom. The fundamental properties of materials
and
systems
are established at the nanoscale.
Nanomaterials, typically on
the
scale of billionths of a meter, or 75,000 times
smaller than the
width
of a human hair, offer different chemical and
physical properties
than
the same materials in bulk form, and have the
potential to form the
basis
for new technologies. This especially includes
the realm of
molecular
biology.
Berkeley
Lab’s Molecular Foundry – actually the research
building around
which
Foundry programs will be developed – will include
six facilities
available
to users from around the world. These include
labs and experts
devoted
to inorganic nanostructures; nanofabrication;
organic,
polymer/biopolymer
synthesis; biological nanostructures; imaging
and
manipulation;
and theory. Its focus will be on the design, synthesis
and
characterization
of both “soft” (biological and polymer) and “hard”
(inorganic
and microfabricated) substances and the integration
of these
into
complex assemblies.
The
SmithGroup of San Francisco designed the structure,
which will
follow
the contours of a hillside site between a materials
research
building
and the microscopy center. Construction will be
coordinated by
Rudolph
and Sletten, Inc. of Foster City. When completed
in 2006, the
Foundry
building will house more than 200 scientists and
support staff,
using
state-of-the-art instrumentation for imaging and
manipulation.
Berkeley
Lab’s facility is one of five in the DOE’s proposed
Nanoscience
Research
Program; others will be developed at Oak Ridge
National
Laboratory,
Brookhaven National Laboratory, Argonne National
Laboratory
and
Sandia National Laboratories/Los Alamos National
Laboratory.
The
possibilities to grow out of this and other initiatives
dedicated to
the
field of nanoscience are virtually limitless.
Some potential
outcomes
that have been suggested include:
*
Carbon nanotubes -- sheets of graphite
rolled into extremely narrow
tubes
a few nanometers in diameter – could be the possible
building
blocks
of future electronic devices.
*
Nanotechnology may one day enable the detection
of disease on the
cellular
level and the targeting of treatment only to tissues
where it
is
needed in a patient’s body, potentially alleviating
many unpleasant
and
sometimes harmful side effects.
*
Nanomanufacturing of parts and materials
“from the bottom up”—by
assembling
them on an atom-by-atom basis—may one day be used
to reduce
waste
and pollution in the manufacturing process.
*
Nanosensors already are being developed
to allow fast, reliable,
real-time
monitoring for everything from chemical attack
to
environmental
leaks.
*
Woven into a cable, carbon nanotubes could
provide electricity
transmission
lines with substantially improved performance
over current
power
lines.
*
Certain nanomaterials show promise for
use in making more efficient
solar
cells and the next-generation catalysts and membranes
that will be
used
in hydrogen-powered fuel cells.
U.S.
Rep. Mike Honda, D-San Jose, was featured speaker
at the
groundbreaking
ceremony. Honda was co-sponsor of the Boehlert-Honda
Nanotechnology
Act of 2003, which authorizes $3.7 billion over
the next
three
years for nanotechnology research and development

FEDERAL NANOTECH CONFUSION SPREADS TO CALIFORNIA
MICHAEL
CRICHTON MISTAKEN FOR RICHARD FEYNMAN
A
report released on January 20, 2004 in Sacramento
indicates that
U.S.
federal confusion over nanotechnology's original
goal has spread to the state of California, where
the concept originated. The report,
"Nanoscience and Nanotechnology: Opportunities
and Challenges in California,"was released
yesterday at a meeting of the state's Joint
Committee on "Preparing California for the
21st Century."
Christine
Peterson, president of the California-based
Foresight Institute, addressed the Committee meeting:
"The original goal for
nanotechnology
-- systems of molecular machines, building cleanly
with atom-by-atom precision, as described by Nobel
physicist Richard Feynman -- is entirely absent
from the report. His name does not even appear.
Instead,
the concept of molecular machines appears only
in the form of 'plagues of self-replicating nanobots,'
as in Michael Crichton's thriller
Prey.
The environmental benefits of molecular manufacturing
may be needlessly delayed by this confusion."
Foresight is the leading public interest group
in nanotechnology.
Ray
Kurzweil, a National Medal of Technology winner
who serves on Foresight's Board of Advisors, commented:
"While the report has its
visionary
elements -- such as projecting 'intracellular
intelligent machines' within 15 years -- the omission
of molecular machine systems is extremely disappointing
and, if not corrected, may contribute to the state
losing
its
natural lead in this area."
Prof.
Ralph Merkle, a winner of the Foresight Institute
Feynman Prize in Nanotechnology and current chair
of the Prize Committee, stated,
"This
confusion was distressing enough when it first
appeared in Washington, but it is far more so
in California, where Feynman set the goal in 1959
at Caltech. It's true that Caltech and Hollywood
- where Michael Crichton
thriller
films are made -- are not far apart geographically,
but Californians should know the difference."
Building
with atomic precision using molecular machine
systems, also known as molecular manufacturing,
is seen as a key technology for
the
environment, medicine, and defense. "This
proposed technology -- the 'nanofactory' - is
our best hope for ending chemical pollution as
we
know it today," said Peterson. "California's
strengths in design, systems engineering, and
software -- combined with its strong interest
in
restoring the natural environment -- give it an
edge in this area. The state's proposed Nanotechnology
Research and Workforce Advisory Council should
include molecular manufacturing as a major focus."

NASA SCIENTISTS USE YEAST TO UNDERSTAND MICROGRAVITY
NASA scientists
will study brewers yeast --typically used to make
bread and beer -- to better understand how microgravity
affects genes, and gain insight into the genetic
basis of how humans respond to microgravity.
Deeper understanding of the molecular mechanisms
of yeast's genetic response to microgravity will
help NASA scientists identify which genes enable
cell survival. Molecular biologists have added
'signature tags' to every gene in the yeast genome,
so that the effects of microgravity on each gene
can be studied. The benefit of using yeast cells
is that it serves as a benchmark microbe for biological
research studying human or other mammalian cells
that have a very large and complex set of genes.
"Understanding gene expression patterns and
how they are altered when cells are grown in the
low-gravity, or microgravity, environment inside
the International Space Station will help scientists
learn how humans respond to gravity," said
principal investigator Dr. Cheryl Nickerson from
the Tulane University Health Sciences Center,
who is working with co-investigator Dr. Tim Hammond
of Tulane University and the Veterans Affairs
Medical Center in New Orleans.
Two Yeast Group Activation Packs (GAP)
that hold the yeast cultures, liquid growth medium
and fixative used to preserve cells in space will
be flown onboard the Russian Progress launch vehicle
13P scheduled to launch on Jan. 29 from the Baikonur
Cosmodrome in Kazakhstan. After a two-day flight,
the payload will be transferred to the International
Space Station, where the experiment will remain
for several months.
"This experiment
will be among the first set of U.S. biological
experiments that will be sent into space since
the Columbia accident," said Dr. Beverly
Girten, chief of the Science Payloads Operations
Branch and small payloads project manager at NASA
Ames Research Center, Moffett Field, Calif.
To activate the experiment, an International Space Station crewmember will
insert a hand crank into the top of the GAP. Turning
the crank will cause the yeast cells to mix with
the liquid growth solution and begin growing.
Following the growth period, the hand crank will
be inserted into the top of the GAP again and
turned, which will allow fixative to mix with
the growing yeast colony, thus preserving the
cells.
The preserved cells will be contained within the
GAP for up to one year following experiment activation.
They will be returned to Earth where scientists
will compare them to identical yeast cells grown
inside a ground control unit. By comparing the
yeast genes expressed during ground-based growth
with those expressed when the organism is grown
in space, scientists can determine how microgravity
alters the genetic expression profile and survival
of cells.
"This experiment is a collaborative effort between peer-reviewed investigators
funded through NASA's Office of Biological and
Physical Research's (OBPR) Fundamental Space Biology
Division, commercial groups working through OBPR's
Space Product Development, and several NASA centers,"
said Girten. "This shared effort is particularly
important since the shuttle fleet is not flying
and there are limited opportunities to conduct
science in space right now." …read

Chemists Make Curved Structures
The
natural world is full of curves and three dimensions,
but the ability to deliberately and rationally
construct such complex structures using nanoscale
building blocks has eluded nanotechnologists who
are eager to add curved structures to their toolbox.
Now
a team of Northwestern University chemists report
they have discovered ways to construct nanoscale
building blocks that assemble into flat or curved
structures with a high level of predictability,
depending on the architecture and composition
of the building blocks. The results are published
in the Jan. 16 issue of the journal Science. ...read

0.09 microns, or 90 nanometers what’s all the
hype about?
Seeing more and more chip manufacturers touting
the word Nano (instead of microns), I decided

this article from September 2003, which helped
me understand this Nano Chip hype just a little
bit more. The Editor
Chip vendors prepare
for 90 nanometer era
by
Tom
Krazit, IDG News Service, Boston Bureau
The 40-nanometer gap that semiconductor
manufacturers are preparing to leap is only as
wide as a sliver of a human hair. Years of research
and millions of dollars have been spent on equipment
and techniques that will enable companies to pack
even more transistors onto a silicon chip, or
reduce the size of powerful processors.

NanoHorizons announces Matrix-less MALDI
now available for Fast, Cost Effective Analysis of Small
Molecules
State
College, PA, USA : NanoHorizons, an emerging leader
in nanoscale material and device technologies,
and Kratos Analytical (a wholly owned subsidiary
of Shimadzu Corporation), a world leader in Mass
Spectrometry, announced the commercial introduction
of a fast, precise technique for small molecule
analysis today.
Kratos Analytical will offer the NanoHorizons’
QuickMass™ targets, which are used to identify
low molecular weight compounds in MALDI (Matrix
Assisted Laser Desorption Ionization) mass spectrometers,
through Shimadzu Biotech, a business unit of Shimadzu
Corporation.
Users of the Axima-QIT™ and Axima-CFR™plus
line of mass spectrometry systems will soon be
able to realize the benefits of high throughput
and lower cost from using disposable, matrix-less,
QuickMass™ targets for small molecule analysis.
QuickMassTM targets increase
selectivity and reduce cross-contamination concerns
for small molecule detection in MALDI-type mass
spectrometers.
“QuickMassTM
targets are a breakthrough in mass spectrometry:
they provide clean and reproducible low molecular
weight spectra by eliminating the matrix compound
used to help laser desorption/ionization in a
MALDI mass spectrometer.
This dramatic improvement is due to the
QuckMassTM target’s non-porous, thin
film surface, which adsorbs and transfers the
laser energy to the sample molecules.
Accordingly, the interfering background
matrix peaks that are commonly observed with MALDI
MS are not present.
Also, the lack of surface porosity prevents
low mass contaminant trapping” says Dr. Stephen
Fonash, founder and Chairman of NanoHorizons

NEW DRESSING FOR WOUNDS DEVELOPED AT HEBREW UNIVERSITY PROMISES
FASTER
AND
IMPROVED
HEALING A novel wound dressing
made of genetically engineered human collagen
that will enable faster and improved healing of
injuries has been developed by researchers at
the Hebrew University Faculty of Dental Medicine.
|
|
Collagen
is the most abundant protein in the animal kingdom,
including humans. It is the major constituent
of connective tissues – tendons, skin, bones,
cartilage, blood vessel walls and membranes. Collagen
fibers are the “warp and woof” of these connective
tissues and are responsible for keeping all the
body’s organs and tissues in their correct functional
structure.
There
are different collagen-containing preparations
on the market today made for treating wounds,
for use in dentistry implants, and in cosmetics.
All of them use collagen made from animal tissues,
which requires specific adaptation in order to
eliminate immunological rejection or to prevent
microbiological infection.
The
dressing developed at the Hebrew University incorporates
an inner layer of genetically engineered, human
recombinant collagen. This material becomes a
soluble, readily enzymatically degradable molecule
in the wound tissue. The molecular fragments that
are thus formed have been shown to play a pivotal
role in the healing process. An outer layer, also
of biological origin, is provided in the wound
dressing to provide initial protection prior to
release of the delicate collagen layer.
Preliminary
animal experiments with the new dressing have
shown substantially faster and better healing,
with rapid formation of new collagen fibers, than
has been possible using older methods.
The
new dressing is the fruit of many years of experimentation
with collagen in the laboratory of Prof. Emeritus
Shmuel Shoshan of the Connective Tissue Research
Laboratory of the Hebrew University Faculty of
Dental Medicine. Prof. Shoshan is the inventor
and chief scientist of Dittekol Ltd., a company
formed in cooperation with the Hebrew University’s
Yissum Research Development Company, to commercialize
the new wound dressing. The company is now negotiating
with investors for further development.

Mini-Van
Sized Rover for 2009
Pathfinder
was the size of a shoebox; the Mars Exploration
Rovers are as big as golf-carts; but a future
Martian rover could be as big as a mini-van. Engineers
from Montana State University are helping to design
the Mars Scientific Laboratory (MSL), which could
make its way to the Red Planet by 2009. Unlike
Spirit and Opportunity, which are solar powered,
the MSL will have a nuclear reactor, so it will
be able to remain operational on the surface for
an entire Martian year (two years on Earth), and
measure long-term climate changes.

Europe :
INP Grenoble, Politecnico di Torino and Ecole Polytechnique
Fédérale de Lausanne are joining forces to set
up an international course for nanotechnology
engineers.
Products implementing microtechnology are already
omnipresent in daily life, but there is still
plenty of scope for miniaturization. To go much
further we must master micrometerand nanometer-scale
technologies, for which specially trained engineers
are essential. Nanotechnology is equally vital
for developing instrumentation, not to mention
the actual teaching of nanoscience.
The aim of the interna-tional engineering degree in nanotechnology is to
prepare graduates for such work. Successful applicants
will benefit from the high-grade teaching and
research capability of three European universities
(Grenoble, Lausanne and Turin). The four-semester
course will include modules on microsystems, microelectronics
design and nanotechnology, in three languages
(English, French and Italian). Students will spend
a semester at each university and a fourth doing
an assignment in industry or a research laboratory,
making a flying start to their career. Teaching
in Grenoble will be based at ENSERG(12) and ENSPG(13),
both part of INP Grenoble.
Between 45 and 60 places will be open in September 2004 to students from
the three universities and the first batch will
graduate in July 2006. This highly original course
will qualify for a joint engineering degree in
nanotechnology awarded by INP Grenoble, EPFL and
Politecnico de Torino. It will be the first course
of its kind in France.

New
g-2 Measurement Deviates Further From Standard
Model
UPTON, NY USA - The latest
result from an international collaboration of
scientists investigating
how the spin of a muon is affected as this
type of subatomic particle
moves through a magnetic field deviates
further than previous
measurements from theoretical predictions. The
result strengthens the
challenge this experiment, known as muon g-2,
first posed to the so-called
Standard Model of particle physics in
February 2001 (based on
data collected in 1999), and then backed with
a more precise result
in July 2002 (based on data collected in 2000).
The new measurement, which
has been submitted to Physical Review
Letters, was announced
today at the U.S. Department of Energy's
Brookhaven National Laboratory,
where the experiment was conducted by
scientists from Brookhaven
and 11 other institutions in the United
States, Russia, Japan,
The Netherlands, and Germany. Based on data
collected in 2001, it
is the first precise measurement of how
negatively charged muons
"wobble" in the magnetic field; the
two
prior results were for
positively charged muons. The precision of the
new result matches the
combined precision of the previously reported
results.
All three results are
in good agreement with one another and with a
long-standing theoretical
prediction of the so-called PCT Theorem
that particles and antiparticles
should wobble at the same rate in a
magnetic field. But when
compared with the latest Standard Model
predictions for the g-2
value, the new experimental result differs
from the most direct theory
calculation by 2.8 standard deviations,
and from a somewhat more
indirect theory calculation by 1.7 standard
deviations, making this
the most significant deviation to date
between experiment and
theory. When the positive and negative muon
results are combined,
the result differs from the direct theory
calculation by 2.7 standard
deviations, and from the indirect theory
calculation by 1.4 standard
deviations. The two theoretical
predictions are in significant
disagreement with one another and have
been under close scrutiny
by the theory community for several years.
The related theory issues
are gradually being clarified and may get
fully resolved soon.
Boston University physicist
Lee Roberts, spokesperson for the muon
g-2 experiment, said,
"The measurement of this property, the
anomalous magnetic moment
of the muon, is a very sensitive test of
the validity of the Standard
Model, and is also sensitive to new
physics beyond the Standard
Model." The Standard Model seeks to
describe the effects of
three of the four known forces on all
subatomic particles. "The
fact that our measurement continues to
deviate from what that
theory predicts may be an indication that we
are seeing new physics
beyond the Standard Model," Roberts said.
While physicists have
known for some time that the Standard Model is
incomplete, the correct
extension to this theory is still a matter of
speculation, with one
leading candidate being supersymmetry - a
theory that predicts the
existence of yet-to-be-discovered companion
particles for all the
known subatomic particles. "One reason there
has been so much interest
in our experiment is that the rate at which
muons wobble in a magnetic
field would be affected by the presence of
new physics, such as supersymmetric
particles, if they exist," said
Roberts. "Historically,
muon g-2 has provided an important constraint
on new theories. Our experiment
is now fourteen times more precise
than the experiment done
at CERN [the European laboratory for
particle physics] in the
1970s. This precision places important
restrictions on potential
new theories."
Added William Marciano,
senior theoretical physicist at Brookhaven
Lab, "The recent
g-2 result strengthens the case for new physics
effects with supersymmetry,
a leading candidate, but it is by no
means definitive. Continued
scrutiny of theory and further running of
the experiment are imperative."
Background on previous
g-2 results
The Standard Model of
particle physics is an overall theory of
particles and forces that
has withstood experimental challenge for
some 30 years. In February
2001, the muon g-2 collaboration published
a finding that deviated
from the value predicted by the Standard
Model. The result of that
experiment, which like the current one, was
