Genetically identical fish can develop strikingly different collective behaviours despite growing up under standardised conditions. Researchers followed ten groups of four Amazon mollies over 55 days, recording how their movements and social relationships developed.

Pseudomonas aeruginosa bacteria use physical collisions with neighbours as information, dynamically switching between disorder and coordinated movement without chemical signalling.

Engineered bacterial communities can use chemical communication to coordinate a metabolic division of labour that no single strain performs as effectively alone.

Bacterial collectives combine signalling, division of labour, environmental memory and local decision rules to achieve capabilities unavailable to individual cells.

Sperm cooperation turns out to be widespread across arthropods rather than an evolutionary curiosity. Researchers mapped sperm traits across hundreds of insects, spiders, crustaceans, centipedes and related animals and found that sperm conjugation — cells physically joining into coordinated groups — has repeatedly appeared, disappeared and reappeared over roughly 600 million years.

Extremophile microbes use quorum sensing to coordinate population-level behaviour even under conditions of extreme heat, cold, salinity or acidity. A new review maps signalling across thermophiles, psychrophiles, halophiles and acidophiles, showing that these organisms produce and detect autoinducer molecules whose accumulating concentration provides local information about population density.

A real-world intrusion campaign used hundreds of coordinated AI agents to compress exploit development and mass compromise into machine-speed parallel work.

AURA Foresight has demonstrated an autonomous wildfire system in which fixed sensors, AI and a drone swarm form a distributed detect-verify-respond chain.

Swarming bacteria and human tissue cells spontaneously create large-scale flow patterns whose dynamics cannot be explained by conventional passive-matter physics.

Fire ants demonstrate several distinct ways that useful group-level behaviour can emerge from decentralised interactions. Research presented by collective-behaviour specialist Takao Sasaki includes workers dynamically self-assembling into pontoon bridges across water, rafts collectively selecting a swimming direction toward visual landmarks, and colonies depositing particles to construct paths across difficult substrates.
