Gene hunters
"Søren Brunak at the Technical University of Denmark and Kasper Lage, now at the Broad Institute in Boston, developed a computational method to predict which proteins most likely cause a particular disease. [...] This study was one of the first to use computational methods to predict a gene–phenotype relationship." article @ TheScientist.com.

Swarm Chemistry
"Swarm Chemistry" is the pilot research project run by Hiroki Sayama in the Department of Bioengineering at Binghamton University, as well as the interactive simulation software developed and used for the project.
We study the collective dynamics of heterogeneous self-propelled particle swarms and develop novel methods of decentralized control and interactive design of self-organizing decentralized systems. Swarm agents steer their motion according to a set of simple kinetic rules, similar to those in Craig Reynolds' "Boids". Each agent in our model has its own kinetic parameters that may be different from others, so that we can mix several different types of swarm agents into a single population and see how they kinetically react and form a dynamic pattern.
