NIST working on 'Deathalizier'
Network World Feb. 19, 2008
*************************
National Institute of Standards and
Technology (NIST) has demonstrated
an optical technique for identifying
tiny amounts of a broad range of
molecules in the breath, potentially
enabling a fast, low-cost screening
tool for disease. NIST researchers
analyze human breath with "frequency
combs" generated by a laser
specially designed to produce a...

Genetic pathway critical to
disease, aging found
KurzweilAI.net Feb. 21, 2008
*************************
University of Wisconsin-Madison
scientists have discovered a gene
expression pathway and specific
enzymes that exert a sweeping
influence over the process of
oxidative stress, the process that
contributes to many diseases and
conditions ranging from Alzheimer's,
heart disease and stroke to cancer
and the process of aging. The
finding is...

Replacing bulk with nanotechnology,
researchers find new way
to keep
fiber-optic signal sharp
Nanowerk News Feb. 20, 2008
*************************
Cornell researchers have
demonstrated that a single photonic
microchip--using four-wave mixing to
amplify an optical signal by
"pumping" with another beam of
light--can replace the bulky bundles
of fiber or electronic amplifiers
now needed to clean up and sharpen
fiber optic signals distorted by
distance. See also Researchers
create a...

Study identifies new patterns of
brain activation used in forming
long-term memories
KurzweilAI.net Feb. 21, 2008
*************************
New York University and Weizmann
Institute of Science researchers
have identified patterns of brain
activation linked to the formation
of long-term memories in a simulated
real-life experience, finding
activity in new areas of the brain:
the temporal pole, superior temporal
gyrus, medial prefrontal cortex, and
temporal parietal...

New rubber promises self-mending
products
New Scientist news service Feb. 20, 2008
*************************
Researchers have built rubber that
only uses hydrogen bonds, not
covalent or ionic, for connecting
crosslinked polymer chains, allowing
the rubber to bind back together
after being snapped or punctured.
The substance self-heals when its
surfaces are brought together under
gentle compression at room
temperature. Applications include
self-healing...

"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
