*************************
The discovery of genes that allow
diatoms to build their hard cell
walls by laying down
sub-micron-sized lines of silica
could be used for computer chip
nanofabrication, claim University of
Washington researchers. They have
found a set of 75 genes specifically
involved in silica bioprocessing in
a species of diatom....
