*************************
Carbon nanotubes are the crucial
chemical ingredient that could make
artificial photosynthesis possible,
say Chinese researchers. Artificial
photosynthesis could efficiently
produce hydrogen that could be used
as a clean fuel and also mop up
carbon dioxide from the atmosphere.
By covalently bonding a large number

mating season die off after the
season is over. When the researchers
used hormones to inhibit the
capases, the song-control regions of
the bird's...

iTnews July 10, 2008
*************************
U.S. scientists from several
organizations are developing a "Gene
Wiki" with the aim of fostering a
flexible, organic archive of human
genetic information. The researchers

Organic dye lets window panes
harvest the Sun
New Scientist news service July 10, 2008
*************************
MIT electrical engineer Marc Baldo
had developed a method to turn up to
20% of incident light into
electricity at a fraction of the
cost of conventional photovoltaic
cells. Exotic organic dyes are
coated onto an ordinary sheet of
glass, trapping light inside the
glass and allowing it to be
channelled to photovoltaic cells
placed along the edges...
