SANYO Breaks Solar Cell Record
Azonanotechnology May 21, 2009
*************************
SANYO Electric has broken its own
record for the world's highest
energy conversion efficiency in
practical size (100 cm2 or more)
crystalline silicon-type solar
cells, achieving a efficiency of
23.0% (until now 22.3%) at a
research level for its proprietary
HIT solar photovoltaic cells....

Rotating Space Elevator Propels its
Own Load
PhysOrg.com May 21, 2009
*************************
West Virginia University physicists
have introduced the idea of a
Rotating Space Elevator (RSE), a
rotating system based on a floppy
string that forms an ellipse-like
shape. It would theoretically use
energy from both geosynchronous
rotation around Earth and the
internal rotation of the string
system around the axis perpendicular
to the Earth...

Diabetes heart risk 'can be cut'
BBC News May 22, 2009
*************************
A Cambridge University study of
33,000 people found getting blood
sugar levels closer to the level for
healthy people -- 4% to 5% -- could
cut the risk of heart attacks by
17%. The current recommended level
in the UK is 7%....

Research team finds important role
for junk DNA
KurzweilAI.net May 20, 2009
*************************
Researchers from Princeton
University and Indiana University
have found that "junk" DNA may
actually perform essential
functions. Genes called transposons
in the single-celled pond-dwelling
organism Oxytricha produce cell
proteins known as transposases,
which influence hundreds of
thousands of DNA pieces to regroup.
Organisms with these genes...
