Cheap, clean drinking water
purified through nanotechnology
Nanowerk News Aug. 13, 2008
*************************
Scientists at the University of
South Australia have discovered a
simple way to remove bacteria and
other contaminants from water using
tiny particles of pure silica coated
with a nanometer-thin layer of
active material based on a...

New nanoparticle film up to 1000
times more effective at killing E.
coli bacteria
Nanowerk News Aug. 14, 2008
*************************
Chemical engineers at the Swiss
Federal Institute of Technology have
created a plastic film coated with a
mix of silver and calcium phosphate
nanoparticles that's up to 1000
times more effective at killing E.
coli bacteria cells than
conventional methods....

Networks of the Future: Extending
Our Senses into the Physical World
PhysOrg.com Aug. 13, 2008
*************************
Los Alamos National Laboratory
computer scientist Sami Ayyorgun has
developed a new communication scheme
for wireless sensor networks with
improved connectivity, energy,
delay, throughput, system longevity,
coverage, and security. Wireless
sensor networks depend on small,
independently powered multihop
sensor "motes" to communicate....

Scientists to study synthetic
telepathy
PhysOrg.com Aug. 13, 2008
*************************
A team of UC Irvine scientists has
been awarded a $4 million grant from
the U.S. Army Research Office to
study the neuroscientific and
signal-processing foundations of
"synthetic telepathy." The
brain-computer interface would use a
noninvasive brain imaging technology
like electroencephalography to let
people communicate thoughts to each
other....

Cooking and Cognition: How Humans
Got So Smart
Live Science Aug. 11, 2008
*************************
A spurt in human intelligence about
150,000 years ago was caused by
eating (mostly) cooked meals, which
would have lessened the energy needs
of our digestion systems, thereby
freeing up calories for our brains,
says researcher Philipp Khaitovich
of the Partner Institute for
Computational Biology in Shanghai.
But some of our most common mental...

'Slow' light to speed up the net
BBC News Aug. 13, 2008
*************************
A huge increase in the speed of the
Internet could be produced by using
metamaterials to replace the bulky
and slow electronics that do the
routing of information carried on
fiber cables, say researchers at
University of California, Berkeley
and the University of Oxford.
Metamaterials could be used to
temporarily store light signals,
with...

More-Efficient Solar Cells
Technology Review Aug. 14, 2008
*************************
Day4 Energy has found a way to cut
the cost of solar power by 25
percent, using a new electrode that,
together with a redesigned
solar-cell structure, allows solar
panels to absorb more light and
operate at a higher voltage. The
company estimates the cost per watt
of solar power would be about $3,
compared with $4 for conventional
solar cells....

Spin flip trick points to fastest
RAM yet
New Scientist Tech Aug. 13, 2008
*************************
Researchers in Germany have built a
Magnetoresistive random access
memory (MRAM) system that is 10
times faster than existing MRAM
systems. MRAM is a faster and more
energy efficient version of the RAM
used in computers today, and
hardware companies think it will in
a few years dominate the...

Quantum strangeness breaks the
light barrier
New Scientist Aug. 13, 2008
*************************
University of Geneva scientists
sent pairs of entangled photons to
labs 18 kilometers apart, showing
that if superluminal signals are
responsible for entanglement, they
must travel at more than 10,000
times the speed of...
