The Interactive Minority Game: A Web-Based Investigation Of Human Market Interactions.
Abstract:
The unprecedented access offered by the World Wide Web brings with it the potential to gather huge amounts of data on human activities. Here we exploit this by using a toy model of financial markets, the Minority Game (MG), to investigate human speculative trading behaviour and information capacity. Hundreds of individuals have played a total of tens of thousands of game turns against computer-controlled agents in the Web-based 'Interactive Minority Game'. The analytical understanding of the MG permits fine-tuning of the market situations encountered, allowing for investigation of human behaviour in a variety of controlled environments. In particular, our results indicate a transition in players' decision-making, as the markets become more difficult, between deductive behaviour making use of short-term trends in the market, and highly repetitive behaviour that ignores entirely the market history, yet outperforms random decision-making.

Automated analysis of bee behavior may yield better robots
A new computer vision system for automated analysis of animal movement - honey bee activities, in particular - is expected to accelerate animal behavior research, which also has implications for biologically inspired design of robots and computers.
Purdue's self-assembled 'nanorings' could boost computer memory
Recent nanotechnology research at Purdue University could pave the way toward faster computer memories and higher density magnetic data storage, all with an affordable price tag.
