Lithium-Ion Batteries for Less
Technology Review July 29, 2008
*************************
A University of Texas at Austin
materials engineering professor has
demonstrated a microwave-based
method for making lithium iron
phosphate that takes less time and
uses lower temperatures than
conventional methods. That could
translate into a lower cost and
safer alternative to the lithium
cobalt oxide used in most
lithium-ion batteries in...

California Institute of Technology
researchers have squeezed a powerful
but microscope onto a single
image-sensing chip and removed the
need for lenses. The cheap, portable
device could be just what medics in
the developing world need to
diagnose diseases such as malaria,
its inventors suggest....

Nanowire lawns make for sheets of
image sensors
New Scientist news service July 28, 2008
*************************
University of California, Berkeley
researchers are growing a mixed
"lawn" of two kinds of nanowires to
make a new kind of cheap,
high-quality image sensor array that
could be made in meter-scale sheets.
The arrays are reliable, flexible
and easy to scale up. They could be
grown to form rolls of tape several
meters in diameter with all the...

Obesity gene 'affects appetite'
BBC News July 27, 2008
*************************
University College London and
King's College London researchers
have found that children carrying a
high-risk version of FTO, the first
gene linked to obesity in Caucasian
populations, find it harder than
others to tell when they are full.
The effect of the gene on appetite
was the same regardless of age, sex,
socioeconomic background and body...

NeuroVista, Emerging from Stealth
Mode, Unveils Technology to Predict
Epileptic Seizures
Xconomy.com July 28, 2008
*************************
Researchers at NeuroVista are
developing an implantable device
designed to predict a seizure before
it happens and warn a patient to get
ready. In their system, an implanted
telemetry device receives brain wave
data and transmits it to a receiver,
where proprietary mathematical
algorithms transform the information
into a real-time warning...

Statins 'may cut dementia risk'
BBC News July 29, 2008
*************************
In a five-year study, University of
Michigan researchers found that
statins--drugs used to lower
cholesterol--may cut the risk of
dementia by half. The exact reason
why is not yet known, but statins
improve blood flow to the brain (by
reducing cholesterol-clogging in
blood vessels) and reduce levels of
insulin. In another study by Boston...

Earlier cancer detection through
microRNA biomarkers
KurzweilAI.net July 29, 2008
*************************
Scientists at Fred Hutchinson
Cancer Research Center and their
colleagues have discovered a new
class of biomarkers for early cancer
detection: microRNAs (small RNA
molecules that regulate gene
expression) released by cancer cells
into the blood. MicroRNAs have some
advantages over protein-based
early-detection systems: they could
be detected...
