Understanding of animal collectives is limited by the ability to track each individual. We
describe an algorithm and software that extract all trajectories from video, with high …

Cells measure a vast variety of signals, from their environment's stiffness to chemical
concentrations and gradients; physical principles strongly limit how accurately they can do …

Schools of fish and flocks of birds can move together in synchrony and decide on new
directions of movement in a seamless way. This is possible because group members …

Zebrafish are rapidly emerging as a powerful model organism in hypothesis-driven studies
targeting a number of functional and dysfunctional processes. Mathematical models of …

Quantifying distributed information processing is crucial to understanding collective motion
in animal groups. Recent studies have begun to apply rigorous methods based on …

Group living is of benefit to foraging individuals by improving their survival, through passive
risk dilution by sheer numbers and through increasingly more active processes, ranging …

Robotic agents that are accepted by animals as conspecifics are very powerful tools in
behavioral biology because of the ways they help in studying social interactions in …
