Researcher Develops Chemical Circuit Using Ion Transistors 27
cylonlover writes news of ion based logic gates. From the article: "While the silicon chips found in the electronic devices that we rely on every day are built around the flow of electrons through circuits, with the development of an 'integrated chemical chip,' a doctoral student in Organic Electronics at Sweden's Linköping University has created the basis for an entirely new circuit technology based on the transmission of ions and molecules. Like silicon-based chips, the integrated chemical chip contains logic gates, such as NAND gates, that form the basis of digital electronics by allowing for the construction of all logical functions."

I've always wondered why they haven't studied insect brains. Flies do way more complex things than any robot so far invented, and would surely be easier to understand than the workings of a mammal brain.
Um, they kinda do. Really, really hard, in fact. [arizona.edu]
