post-silicon transistor  IBM's new work shows that flexible low-
power circuitry could be built with strongly correlated
materials  Exploring methods of computing without silicon, IBM
has found a way to make transistors that could be fashioned into
virtual circuitry that mimics how the human brain operates.  The
proposed transistors would be made from strongly correlated
materials, which researchers have found to posses
characteristics favorable for building more powerful, less
power-hungry computation circuitry.   Parkin's team is the first
to convert metal oxides from an insulated to conductive state by
applying oxygen ions to the material. The team published details
of the work in this week's edition of the Science journal.  The
circuitry used in today's computer processors, memory and other
components is made from large numbers of integrated transistors
built from silicon wafers. Conventional transistors work by
applying a small voltage across a
