NewsCred Goes Public With
Credibility-Based News Source
TechCrunch Aug. 19, 2008
*************************
NewsCred, the news aggregator that
ranks stories by the credibility of
their source, has launched to the
public. Instead of relying on
popularity, as many social news
sites do, NewsCred instead allows
users to rate each story, author,
and publication's credibility, which
is then plugged into an algorithm to
determine the site's prominent...

Scientists Move Optical Computing
Closer to Reality
PhysOrg.com Aug. 19, 2008
*************************
University of Pennsylvania
scientists have theorized a way to
increase the speed of pulses of
light traveling in nanoparticle
chains (acting as miniature
waveguides) to 2.5 times the speed
of light by altering the particle
shape. As the velocity of the light
pulse increases, so too does the
operating bandwidth of a waveguide,
thus increasing...

Efficient technique enables
thinking
PhysOrg.com Aug. 19, 2008
*************************
Scientists at the Max Planck
Institute for Neurobiology in
Martinsried have found a completely
new, faster technique nerve cells
use to evaluate the quality of the
cells they contact in a very time-
and energy-saving way. Instead of
synapses (which require up to two
days to become fully functional),
neurons use calcium for thinking.
When a...

Gasoline produced from biomass
could be in fuel tanks by 2010 with
new technology
PhysOrg.com Aug. 19, 2008
*************************
Texas A&M University scientists
have developed a process to make
converting biomass to high-octane
gasoline possible, at $1.70 and
$2.00 per gallon. Biomass includes
garbage, biosolids from wastewater
treatment plants, green waste such
as lawn clippings, food waste, and
any type of livestock manure.
Additionally, since it does not use
crops...

Google to Invest in Geothermal
New York Times Aug. 20, 2008
*************************
Google.org is investing a little
over $10 million in the development
of Enhanced Geothermal Systems, or
EGS. EGS drills deep -- miles down
-- to access layers of heated
granite that exist underfoot
everywhere on the planet. Water can
be circulated downward for heating,
and then upward to drive turbines
and generate electricity....

Biomarkers reveal our biological
age
PhysOrg.com Aug. 19, 2008
*************************
Scientists at Max Planck Research
Group for Stem Cell Aging in Ulm
have identified a group of proteins
that reveal the biological age of a
person. These biomarkers could be
used in medicine to adapt therapies
for older people to their individual

Body May Reject Transplanted Human
Embryonic Stem Cells
ScientificAmerican.com Aug. 19, 2008
*************************
Researchers at Stanford University
School of Medicine found that mice
mounted an immune response after
being injected with human embryonic
stem cells (hESCs). The result: all
the transplanted stem
cells—which hold the promise of
maturing into several different
types of tissue—were dead
within a...

A new imaging system that
highlights cancerous tissue in lurid
colors should help surgeons remove
every last trace of cancer without
harming the surrounding tissue. A
real-time surgical imaging system

surgical area overlaid with images
of hidden features such as cancer
cells, blood vessels, and lymph...
