Riding D-Wave
Technology Review May/June 2008
*************************
In November of last year, with $60
million in funding, D-Wave
demonstrated what it claimed was a
28-qubit adiabatic quantum computer,
based on a design by MIT quantum
computing scientist Seth Lloyd. Now,
the company's scientists are
attempting to demonstrate the
fundamentally quantum-mechanical
nature of their...

'Planetary sunshade' could strip
ozone layer by 76%
New Scientist Environment April 24, 2008
*************************
Planetary engineering projects to
cool the planet could backfire quite
spectacularly: a new model shows
that a "sulphate sunshade" would
punch huge holes through the ozone
layer above the Arctic. To make
matters worse, it would also delay
the full recovery of the Antarctic
ozone hole by up to 70...

Space 'spiderwebs' could propel
future probes
NewScientistSpace April 25, 2008
*************************
A new type of interplanetary solar
sail has been woven by scientists at
Finnish Meteorological Institute.
The spiderweb-like sail is designed
to catch the wind of ionized gas
that blows from the Sun, carrying
spacecraft to the outer reaches of
the solar system, or letting them
tack back and forth through the
asteroid belt on exploration or...

NASA's Ames Research Center said
Thursday it would team with m2mi to
develop "nanosats" that weigh
between 11 and 110 pounds. The
agency says large groups of
nanosatellites can be grouped in a
constellation, which will be placed
in low-Earth-orbit to offer new
"fifth generation"
telecommunications and TCP/IP-based
networks and related...

Microsoft researchers are
developing an armband worn on the
forearm that recognizes finger
movements by monitoring muscle
activity. The MUCI (muscle-computer
interface) is intended to make
controlling computers and gadgets

New Scientist news service April 24, 2008
*************************
University of Michigan researchers
have created a simple-to-make planar
"superlens" that can focus 10 times
more sharply than a conventional
lens. It could shrink the size of
features on computer chips by
focusing light into smaller spots
during photolithography to etch
smaller features onto computer
chips, and facilate wireless
transmission...

Creating Faster Integrated Circuits
by Slowing Light
PhysOrg.com April 24, 2008
*************************
UC San Diego researchers have shown
that slowing down light can enable
the efficient transport of
information optically rather than
with wires, a breakthrough that
could significantly enhance computer
performance and lower the power
required by future computer systems.
However, slow-light-based systems
are also very susceptible to the
effects...

By 2015, babies might have their
entire DNA read at birth, as costs
of sequencing plunge below $100. The
first full human-genome sequencing,
completed in 2003, took 13 years and
cost $437 million. James Watson's
2008 sequencing, carried out by 454
Life Sciences, took only two months
and cost about $1 million. Other
companies, such as Illumina...

Study reveals how neurons generate
movement
KurzweilAI.net April 25, 2008
*************************
University of California San
Francisco researchers have learned
how neurons fire when orchestrating
visual tracking. They found that
individual neurons do not fire
independently across the entire
duration of a motor function, as has
been traditionally thought. Instead,
the neurons coordinate their
activity with other neurons.
