Swarming 'swells' locusts' brains | locust, brain, swell, collaboration, social, neuroscience, insect, swarm | Swarming locusts not only look different and act differently to solitary locusts, they also have much larger brains. | 20100525 | peek | visit | add/edit |

Bee swarms follow 'pied pipers' | signal, bee, swarm, control, animal, collective intelligence | A tiny group of bees act like "pied pipers" to trigger the onset of bee swarms report scientists. By buzzing a "piping" signal the bees are able to initiate an explosive departure from the hive. Bees are known to use signals to tell the colony when to swarm but which bees had the power to make this decision was unclear. Now scientists have identified a small oligarchy of individual bees that hold the key to swarm behaviour. | 20100315 | peek | visit | add/edit |

'Smart dust' to explore planets | swarm, astronomy, exploration, nanotech, dust, planet, Mars, network | Computer chips of the size and sophistication required to meet the challenge already exist. ... For a planet like Mars, smart dust particles would each have to be the size of a grain of sand. ... Wireless networking would allow these particles to form swarms, and Dr Barker's team has carried out mathematical simulations to see how this would work. ... We envisage that most of the particles can only talk to their nearest neighbours but a few can communicate at much longer distances. ... In our simulations, we have shown that a swarm of 50 dust particles can organise themselves into a star formation, even in turbulent wind. ... The ability to fly in formation would allow the processing of data to be spread, or "distributed" between all the chips, and a collective signal to be beamed back to a "mothership". (How many of those are already operating on Earth?! [TF]) | 20070418 | peek | visit | add/edit |

Particle swarm optimization | complexity, group, social, artificial intelligence, swarm, algorithm | Particle swarm optimization (PSO) is an algorithm modelled on swarm intelligence that finds a solution to an optimization problem in a search space, or model and predict social behavior in the presence of objectives. | - | peek | visit | add/edit |

Locust swarms 'high' on serotonin | locust, swarm, serotonin, depression | When food runs short, they slowly become clustered together and enter their "gregarious" phase, culminating in an aggressive swarm. Prior to swarming, the locusts undergo a series of dramatic physical changes - their body colour darkens and their muscles grow stronger. ... They found that locusts behaving the most gregariously (in swarm-mode) had approximately three times more serotonin in their systems than their calm, solitary comrades. | - | peek | visit | add/edit |
