Genetic building blocks may have
formed in space
NewScientist news service June 13, 2008
*************************
Ring-like carbon molecules that are
essential for the creation of
nucleic acids like DNA and RNA might
have formed in a meteorite called
Murchison before it landed in
Australia in 1969, according to Zita
Martins, a chemist at Imperial
College London. The Murchison
meteorite (Chip Clark/Smithsonian
Institution) The ratio of carbon-13
to...

Researchers create molecule that
nudges nerve stem cells to mature
PhysOrg.com June 15, 2008
*************************
Researchers at UT Southwestern
Medical Center have created a small
molecule, "Isx-9," that stimulates
nerve stem cells to begin maturing
into nerve cells in culture. The
finding might someday allow a
person's own nerve stem cells to be
grown outside the body, stimulated
into maturity, and then re-implanted
as working nerve cells to treat...

Roadrunner supercomputer puts
research at a new scale
PhysOrg.com June 12, 2008
*************************
Los Alamos National Laboratory
researchers are using the lab's new
Roadrunner petaflop supercomputer to
model the human visual system, as a
test. The "PetaVision" simulaton
models more than a billion visual
neurons, reaching a new computing
performance record of 1.144
petaflop/s. Based on the results of
these trials, Los Alamos researchers...

How to build a quantum eavesdropper
the physics arXiv blog June 13, 2008
*************************
Researchers at the University of
Tskuba in Japan have designed a
quantum eavesdropper that can
extract information from a quantum
message without the sender or
receiver knowing. It exploits a
loophole: the ability to make
imperfect copies of quantum states
without destroying the...

Microchip sets low-power record
with extreme sleep mode
PhysOrg.com June 13, 2008
*************************
The Phoenix Processor microchip,
developed at the University of
Michigan, uses 30,000 times less
power in sleep mode--30
picowatts--and 10 times less in
active mode than comparable chips
now on the market. It would allow
for a sensing system, including the
battery, to be 1,000 times smaller
than the smallest known sensing
system today. A...

Nuclear Ring Reportedly Had
Advanced Design
New York Times Jan. 15, 2008
*************************
Investigators have found electronic
blueprints for an advanced nuclear
weapon on computers in several
cities around the world. It belonged
to the nuclear smuggling network run
by Abdul Qadeer Khan, the rogue
Pakistani nuclear...

'Microscope on a chip' to give four
times the detail
NewScientist news service June 13, 2008
*************************
A new scanning electron microscope
(SEM) design by physicist Derek
Eastham could achieve a resolution
around four times better than
existing SEMs--as low as 0.01
nanometers (roughly the distance
between a hydrogen nucleus and its
electron). It also produces a beam
with about 100 times less energy
than usual in an SEM, lowering the
cost and...

*************************
Plastics unite to make unexpected
'metal'
NewScientist.com news service June 15, 2008
*************************
Attaching a micrometer-thick
crystal of the organic polymer TTF
to a similarly thin organic crystal
of the polymer TCNQ results in a
2-nanometer-thick strip along the
interface between the two crystals
that conducts electricity as well as
a metal, Delft University of
Technology researchers have found.
The discovery could lead to new ways
of...
