Flexible, Nanowire Solar Cells
Technology Review Feb. 6, 2008
*************************
Researchers at McMaster University
have grown light-absorbing nanowires
made of high-performance
photovoltaic materials on thin but
highly durable carbon-nanotube
fabric. They've also harvested
similar nanowires from reusable
substrates and embedded the tiny
particles in flexible polyester
film. Both approaches, they argue,
could lead to solar...

Charles Ostman discusses sythetic
biology and the Singularity
KurzweilAI.net Feb. 6, 2008
*************************
"Historian of the future" Charles
Ostman will discuss synthetic
biology, junk DNA, the Singularity,
and possible genetic modification of
the human species from an external
source on the nightly national
CoastToCoast AM radio show on
Wednesday February 6th....

Creating Ethanol from Wood More
Efficiently
Technology Review Feb. 5, 2008
*************************
A type of bacteria that helps
termites digest wood could be key to
making ethanol cheaply from wood and
grass. ZeaChem, a startup based in
Menlo Park, CA, has developed a
process based on the Moorella
thermoacetica bacteria that can
produce 50 percent more ethanol from
a given amount of biomass than
conventional processes can....

How Our Genomes Control Diversity
Scientific American Feb. 5, 2008
*************************
Two research efforts have
determined DNA recombination
mechanisms that underlie population
diversity, both how it happens and
where in the genetic code it occurs.
In one study, University of Chicago
scientists examined patterns in DNA
recombination, the process by which
a person's genome is consolidated
into one set of chromosomes to pass
onto...

Remote-control DNA 'pistons' could
power tiny robots
NewScientist.com news service Feb. 5, 2008
*************************
Researchers in the UK and Germany
have demonstrated structures that
could eventually act as motors for
nanoscale robots: nanoscopic DNA
pyramids that change shape when sent
different chemical signals. Other
researchers have built DNA devices
capable of walking along proteins or
functioning like nanoscopic robot
arms, but precise control of...

With Mini in-vivo Robots, Anyone
Can do Surgery
PhysOrg.com Feb. 5, 2008
*************************
Scientists have designed a way to
allow individuals with non-medical
backgrounds to perform minimally
invasive surgery using a
millimeter-sized camera robot
attached to a tether. Unlike
expensive room-sized surgical
robots, mini in-vivo robots are
inexpensive and mobile enough to
support emergency surgeries almost
anywhere, from the...

Embryos Created With DNA From 3
People
PhysOrg.com Feb. 5, 2008
*************************
Newcastle University researchers
have created human embryos
containing DNA from two women and
one man, a procedure that could
potentially prevent conditions
including epilepsy, diabetes and
heart failure. The preliminary
research has raised concerns about
the possibility of genetically
modified babies, but the scientists
say the embryos are...

Drug PTC124 fights cystic fibrosis
PhysOrg.com Feb. 5, 2008
*************************
An experimental drug that has
proven effective in treating
muscular dystrophy also works for
cystic fibrosis, according to
researchers at the University of
Alabama at Birmingham. The compound
PTC124 helps to "rescue" faulty
proteins that lead to illnesses. The
drug holds promise in treating more
than 2,400 genetic diseases caused
by a certain...
