A New Treatment for Alzheimer's?
Technology Review Jan. 15, 2008
*************************
A drug commonly used to treat
arthritis caused a dramatic and
rapid improvement in patients with
Alzheimer's disease, according to
physicians in California. However,
scientists and others not involved
in the work worry that the report,
which was based on trials in a few
patients and hasn't been
independently confirmed, may offer
little more than...

Iron nanobeads can control immune
system
New Scientist news service Jan. 15, 2008
*************************
Rat cells' immune response has been
switched on and off with a magnetic
field, a technique that could
control treatment of allergies and
other illnesses more precisely.
Children's Hospital in Boston
researchers created iron nanobeads
that bind to receptor molecules on
the surface of rats' immune cells.
When exposed to a magnetic field,
the...

Cameraphone used to control
computers in 3D
NewScientist.com news service Jan. 15, 2008
*************************
York University-developed prototype
software allows a camera-equipped
cellphone to control a computer as
if the phone were a
three-dimensional mouse. On-screen
items can be moved or manipulated
simply by waving a handset in front
of a screen....

Semantic Web takes big step forward
InfoWorld Jan. 15, 2008
*************************
The Semantic Web is getting a
critical boost Tuesday from the
World Wide Web Consortium (W3C). The
W3C is publishing SPARQL (pronounced
"sparkle") query technology, a
Semantic Web component enabling
people to focus on what they want to
know, rather than on the database
technology or data format used to
store data....

Self-Paced Brain-Computer Interface
Gets Closer to Reality
PhysOrg.com Jan. 15, 2008
*************************
University of British Columbia
researchers have developed a
self-paced brain-computer interface
with both a low false-positive rate
and a high true-positive rate.
Improved software and other methods
allows the interface to detect
neurological phenomena in an
environment with a very low
signal-to-noise ratio....

Engineers Create Carbon
Nanopipettes That Are Smaller Than
Cells and Measure Electric Current
KurzweilAI.net Jan. 16, 2008
*************************
University of Pennsylvania
engineers and physicians have
developed a carbon nanopipette that
measures electric current and
delivers fluids into cells. The
researchers developed the tool,
ranging in size from a few tens to a
few hundred nanometers, to probe
cells with minimal intrusion and
inject fluids without damaging or
inhibiting cell...

Graphene quantum dot may solve some
quantum computing problems
PhysOrg.com Jan. 15, 2008
*************************
Researchers at the Solid State
Physics Laboratory in Zurich have
proposed a method to use a tunable
graphene quantum dot to create
qubits (quantum bits). A
graphene-based qubit could solve
some of the problems found in using
gallium arsenide quantum dots in
spin-based quantum computers....

Pushing The Limits Of Computer Chip
Miniaturization
Science Daily Jan. 14, 2008
*************************
European researchers are developing
chips with 32 and 22 nanometer
features. To reduce the quantum
effects seen at this size, such as
current leakage at the logic gate,
the researchers in the Pullnano
project discovered a method to
reduce gate leakage 100-fold by
using a hafnium compound-based
insulator with higher dielectric
strength than...

Food from cloned animals deemed
safe in US
Nature News Jan. 15, 2008
*************************
The FDA has announced that food
from cloned animals and their
offspring is safe for consumption.
However, the US Department of
Agriculture urged food producers to
preserve a voluntary moratorium on
marketing food from cloned animals
until regulators can determine how
best to introduce them into the US
meat and dairy market....
