Discovery by UC Riverside
physicists could enable development
of faster computers
PhysOrg.com June 24, 2008
*************************
Physicists at UC Riverside have
made an accidental discovery in the
lab that has potential to change how
information in computers can be
transported or stored. The
researchers were experimenting with
ferromagnet/semiconductor (FM/SC)
structures, which are key building
blocks for semiconductor spintronic
devices (microelectronic devices
that...

Physicists Store Images in Vapor
PhysOrg.com June 23, 2008
*************************
Physicists from the Technion-Israel
Institute of Technology and the
Weizmann Institute of Science have
stored images for up to 30
microseconds in rubidium vapor.
Storing images in vapor could be
useful for image processing and
correlation applications, quantum
information processing, and quantum
communication. The scientists also
predict that...

Tethered molecules act as
light-driven reversible nanoswitches
PhysOrg.com June 23, 2008
*************************
Penn State University and Rice
University scientists have developed
a new technique for attaching
light-sensitive organic molecules to
metal surfaces that allows the
molecules to be switched between two
different configurations in response
to exposure to different wavelengths
of light. (Paul Weiss lab, Penn
State) This research advance is...

10 Audacious Ideas to Save the
Planet
Popular Science June 13, 2008
*************************
Solar power from space, super-hairy
plants to reflect enough
near-infrared energy back into space
to cool regional temperatures by two
degrees Fahrenheit, and turning the
carbon dioxide from your car into
fuel are among creative ways
scientists are finding to clean up
the...

Gartner expects 2 billion PCs will
be in use by 2014
Computerworld June 23, 2008
*************************
As the number of PCs in use around
the world passed the 1 billion mark,
Gartner Inc. is estimating that the
total will double in just another
six years. The number of PCs in use
worldwide is now growing at a rate
of just under 12% a year. This is
largely coming from expanding
emerging markets, driven by the
explosive expansion of broadband and...

Quantum dots improve effectiveness
of gene silencer
KurzweilAI.net June 24, 2008
*************************
University of Washington and Emory
University researchers have used
quantum dots (fluorescent balls of
semiconductor material around six
nanometers across) to improve how
gene-silencing RNA (siRNA, small
interfering RNA) is delivered into
cells for diagnostic and therapeutic
use (by blocking dangerous genes).
Quantum dot-siRNA complex...

Subtle nervous system abnormalities
may predict risk of death in older
individuals
KurzweilAI.net June 24, 2008
*************************
University of Florence researchers
and colleagues have found that
subtle but clinically detectable
neurological abnormalities such as
reduced reflexes or unstable posture
help predict the risk of death and
stroke in otherwise healthy older
adults--possibly a sign of early
brain damage. These results suggest
that a standard neurological exam...

Arterial calcium scans can predict
death risk
HealthDayNews June 22, 2008
*************************
Harbor-UCLA Medical Center
researchers have found that scanning
the heart's arteries for calcium
deposits accurately predicts the
overall death risk for American
adults. The Harbor-UCLA study
followed more than 35,000 people,
ages 40 to 80, after they had a
coronary artery calcium scan by
electron beam tomography. Increased
coronary artery...
