Some things that caught my eye in the reports from the recent AAAS meeting in Chicago

Mathemetician Elwyn Berlekamp has devised a version of the Chinese game Go, called Coupon Go, where (experienced) players are invited to assign a value to particular moves. This will, hopefully, help in solving this particularly complex game. Unlike for instance chess, where computerized players have beat even the top players, even the best Go programs apparentely don't manage to perform beyond an intermediate amateur level. A slightly older talk by Berlekamp about Coupon Go is here on Youtube.

Colin Camerer gave a talk called Interface Between Cognitive Psychology and Economics. Sadly I can't seem to find anything more indepth about it than the press release. Among other things he describes some interesting empirical findings about how people play so called LUPI (lowest unique positive integer) games, where the winner is the person who picks the lowest number that is picked by only one player. That part seems to be based on this paper.
