New Alzheimer's Treatment Completes
First Phase Of Testing
Science Daily Jan. 28, 2008
*************************
A beta-secretase inhibitor molecule
designed by a Purdue University
researcher to stop the debilitating
symptoms of Alzheimer's disease has
been shown in its first phase of
clinical trials to be safe and to
reduce plasma amyloid beta, a key
biomarker for the disease. The
molecule prevents the first step in
a chain of events that leads to...

Looking into the Brain with Light
Technology Review Jan. 29, 2008
*************************
An Israeli company called OrNim has
developed a new noninvasive
diagnostic "ultrasonic light
tagging" technology that could give
doctors the single most important
sign of brain health: oxygen
saturation. Information on
oxygenation in specific regions of
the brain would be valuable to
neurologists monitoring a
brain-injured patient: it could be...

Tiny Living Machines
Technology Review January/February 2008
*************************
Harvard University researchers have
developed devices made of heart
tissue that could screen drug
candidates and be used to power
implantable robots. The muscle cells
would be fueled by sugar in the
bloodstream and maintained by the
same repair mechanisms that keep the
heart pumping. And the muscle-coated
film could also be used to
regenerate...

Invention: Nanotube X-ray enhancer
NewScientist.com news service Jan. 28, 2008
*************************
Rice University scientists have
invented a better X-ray for soft
tissues. They propose to fill carbon
nanotubes with iodine, coat them
with a film of protein that bonds
with specific types of cell, and
allow the tubes to become embedded
in the cells of interest. As well as
giving a greater choice of targets
for analysis, this should allow...

Couch potato lifestyle may speed up
ageing
NewScientist news service Jan. 29, 2008
*************************
Researchers at St. Thomas' hospital
in London have found that people who
did not exercise in their spare time
had shorter telomeres than very
active people. Telomeres shorten
each time a cell divides, and when
they become too short a cell can no
longer divide, so telomeres act as a
kind of timer counting down our
biological age. Exercise can...

Mobile video at Davos
BBC News dot.life Jan. 28, 2008
*************************
One of the talking points to emerge
from Davos this year is Reuters' use
of online video to report instantly
on events, using mobile phones. More
interestingly, Robert Scoble, a
blogger who works for Fast Company,
was recording interviews on his
Nokia N95 mobile phone and sometimes
going live, using a software tool
called Qik for streaming...
