Topological vs. Metric distance

Basically all existing models of collective animal behaviour (bird flocks, fish schools, etc) assume that the interaction between different individuals depends on the metric distance, just as in physics. This implies, for example, that two birds 5 meters apart interact more strongly than two birds 10 meters apart.

Models developed by biologists are based on a “behavioural zones” scheme, where each zone is associated to one of the three basic ingredients of all models: short range repulsion, alignment, long range attraction.… Read the rest

Protein Folding

Protein Folding is a specific chemical and physical transition by which a linear sequence of aminoacids finds its functional (native) three dimensional structure. The theoretical study of protein folding represents perhaps one of the most challenging research with a marked interdisciplinary character, where biology, chemistry, physics, mathematics and computer science can fruitfully interact each other.

Our activity in this field concerns the prediction of folding mechanisms by the knowledge of tertiary structure only.

STARFLAG: a project on collective animal behaviour

Collective animal behaviour is a fascinating phenomenon. How does global co-ordination emerge in a flock of thousands starlings swirling at dusk? How does a school of sardines organize in a circular pattern? What is the evolutionary function of collective behaviour? Is it purely defensive, or has it some other purpose, perhaps social? INFM-CNR was the leader node of a European project – FP6-NEST 12682 STARFLAG (2005-2008) – dedicated to the study of collective animal behaviour.Read the rest
