Biosentients - Science Biology… etc

by Nicole Miller. Denizens of oceans, lakes and even wet soil, diatoms are unicellular algae that encase themselves in intricately patterned, glass-like shells. Curiously, these tiny phytoplankton could be harboring the next big breakthrough in computer chips. Diatoms build their hard cell walls by laying down submicron-sized lines of silica, a compound correlation to the key material of the semiconductor industry - silicon. "If we can genetically control that process, we would have a whole new way of performing the nanofabrication used to make computer chips," says Michael Sussman, a University of Wisconsin-Madison biochemistry professor and director of the UW-Madison's Biotechnology Center........
