Controlling the Size of
Nanoclusters: First Step in Making
New Catalysts
KurzweilAI.net July 10, 2008
*************************
Researchers from the U.S.
Department of Energy's (DOE)
Brookhaven National Laboratory and
Stony Brook University have
developed a new instrument that
allows them to control the size of
nanoclusters -- groups of 10 to 100
atoms -- with atomic precision. The
device could allow for making
nanoclusters with predetermined
size, structure and...

Nanotubes Hold Promise for
Next-Generation Computing
Wired July 9, 2008
*************************
Two groups of researchers have
recently published papers
demonstrating advances in creating,
sorting and organizing carbon
nanotubes so they can be used in
electronics. Stanford electrical
engineers addressed the problem of
getting nanotubes straightened out
so they could be put to work in
chips, by growing the nanotubes on
crystalline quartz,...

Robots aim to top humans at air
hockey
EE Times July 8, 2008
*************************
An upgraded robot developed by
General Electric Fanuc and Nuvation
Research can beat most human air
hockey players, its developers
claim. A video system that tracks
the puck's position sends
coordinates to a special PC board
every 10 milliseconds. So far, the
robot has defeated every human
opponent when running in 32-bit
mode, averaging...

Smart contact lens feels the
pressure of glaucoma
NewScientist.com news service July 9, 2008
*************************
University of California, Davis
researchers have made a contact lens
with a built-in pressure sensor that
could help monitor conditions such
as glaucoma and ocular hypertension.
Prototype lenses with pressure
sensors (Wiley-VCH Verlag GmbH and
Co) PDMS (polydimethylsiloxane, the
organic polymer traditionally used
for contact lenses)...

New Technique Harvests Stem Cells
at Earlier Stage
HealthDay News July 9, 2008
*************************
Researchers at Vrije Universiteit
Brussel have derived human embryonic
stem cells (hESC) earlier in the
development stage of a blastomere
(when it only has four cells), so
the whole embryo is not destroyed.
Previously, scientists were able to
derive hESC lines at the 8-cell
stage, but that method had variable
success rates and required the...

Common drugs may combat aging
disease
New Scientist news service July 9, 2008
*************************
University of Oviedo (Spain)
researchers have found that two
common drugs--statins (used to
reduce cholesterol) and
bisphosphonates (used to curb
osteoporosis)--have reversed the
effects in mice of progeria, a rare
genetic disease that causes
premature aging. Progeria
accelerates aging from early
childhood and is usually fatal
before puberty....

Assembling Nanotubes
Technology Review July 10, 2008
*************************
Stanford University and Samsung
Advanced Institute of Technology
researchers have developed a new
method for sorting single-walled
carbon nanotubes by electronic type
and arranging them over a large
area; it could be useful for
manufacturing high-performance
displays and other electronic
devices. (Melburne LeMieux /
Stanford University)...

"Fantastic Voyage.... takes pains
to say: 'this is not a panacea, it's
just a beginning. You must make your
own path, keep up with research and
be a scientist.' This is a
refreshingly no-nonsense attitude,
and it's one of the main reasons
that I have a high degree of trust
and respect for the work that Ray
Kurzweil and Terry Grossman have
made available to us. -Mike T." To
