Using a light touch to measure
protein bonds
KurzweilAI.net June 30, 2008
*************************
MIT researchers have used optical
tweezers (light beams) to achieve a
precise measurement of the strength
of bonds between two protein
molecules important in cell
machinery. They focused on proteins
that bind to actin filaments, an
important component of the
cytoskeleton that provide structural
support, help the cell crawl across
a surface or...

Scientists Identify the Brain's
Activity Hub
New York Times July 1, 2008
*************************
The cerebral cortex has a central
clearinghouse of activity below the
crown of the head that is widely
connected to more-specialized
regions in a large network similar
to a subway map, researchers at
University of Lausanne, Harvard, and
Indiana University have found.
(Indiana University) They used a new
technique called diffusion spectrum...

Designer protein tackles HIV
Nature News June 30, 2008
*************************
Researchers at Sangamo BioSciences
and the Abramson Family Cancer
Research Institute have built a
custom-designed enzyme that can make
T cells (a type of immune cell)
resistant to HIV by disabling
(cutting the gene to make it
nonfunctional) the T cell gene CCR5.
The technique could allow scientists
to design enzymes that bind to the
genome at...

Tongue Drive system lets persons
with disabilities operate powered
wheelchairs, computers
KurzweilAI.net July 1, 2008
*************************
Georgia Institute of Technology
researchers have developed a
tongue-driven system for severely
disabled individuals that lets them
operate a computer, control a
powered wheelchair, and interact
with their environments simply by
moving their tongues. The system
uses a rice-grain-sized magnet
implanted in or attached to the
tongue. Movement of...

'Puncture repair kit' may minimize
brain trauma
Nature News June 30, 2008
*************************
Purdue University researchers have
designed a simple treatment to
reduce the impact of blunt traumas
to the brain by mechanically
"patching" burst cell membranes.
Brain-injured rats that were
injected with polyethylene glycol
(PEG) within four hours of the
injury had improved behavioral
results compared with the control
group. The therapy...

New Electrostatic-based DNA
Microarray Technique Could
Revolutionize Medical Diagnostics
KurzweilAI.net June 30, 2008
*************************
Researchers with the Lawrence
Berkeley National Laboratory
(Berkeley Lab) have invented a
technique in which DNA or RNA assays
(for genetic profiling and disease
detection) can be read and evaluated
without the need for elaborate
expensive chemical labeling or
sophisticated instrumentation. A new
method for reading DNA (or RNA)
microarrays is...
