The Royal Society of Chemistry has awarded a Belfast-based boffin a prize for developing "intelligent supermolecules" which are on an intellectual level with (some) human children - able to win games of noughts and crosses.
The unfeasibly tiny nanobrain developments sprang from the normal-sized brain of Professor A Prasanna de Silva of Queen's Uni, recipient of the 2008 RSC Sensors Award, and those of his collaborators.

The latest developments build on fluorescent sensor molecules previously developed by de Silva's team, which have already seen widespread use in medical diagnostic equipment. These "catch and tell" molecules emit light when they encounter specific chemicals in a blood sample. Now, Prof de Silva and his fellow boffins have apparently devised even niftier glow-molecules which can act as logic gates.
"Logic gates are what drive current computers," says (http://www.ch.qub.ac.uk/staff/desilva/) the prof. "The first molecular logic gates were built in Belfast a few years back and a range of gates such as YES, NOT, AND, OR, NOR and INHIBIT are now available ... These artificial systems use chemical inputs and light output, reversing the natural roles existing within the eye.
"One of our own contributions has been to persuade molecules to perform arithmetic operations. Small molecules can now add one and one to get two, just like children. It is clear that small molecules can perform small-scale computational operations in small spaces where semiconductors cannot go in spite of all their power."
According to the Queen's Uni release, other smarty-cules developed in the States from Belfast research can "play games like tic-tac-toe and win against human opponents".
It seems that the RSC prize brings Professor de Silva £500 and "a silver medal", which is nice. Also, the existing blood-chemistry cassette tech has apparently done $40m of sales since 1997. ®
All I can say is, holy shit.

My computer can do all of that, and it is not as intelligent as a two year old child. Intelligence is a different thing.

There are a finite number of possible games. Solving it is not difficult. Indeed, any program that can't win (or at least draw) every single game is pretty shit (if that is its objective).

I think the researcher didn't intend to confuse game-playing algorithms with intelligence. His real point was to announce there has been some success in shrinking logic gates to molecular sizes.

Indeed. It is even possible to make a program that "learns" how to play the game, making aleatory moves in the first games and then improving its performance by discarding moves that lead to defeat, until it becomes unbeatable.

This is what impressed me about the article, not the over-inflated claims of intelligence. If a way can be found to pack these molecules at significant densities into CPUs, then the potential processing power is amazing. And most likely it will operate at lower temperatures too.

I wonder how they make an interface to such small things. They're very close to the limits of the uncertainty principle. If something is too small, you go to measure its state and you just disturbed what you're trying to measure.

Indeed, I would even say it is a completely non-associated thing. The computers can get faster and faster and smaller and smaller, you will still miss the creativity of a living human.
