Some baby ants don’t ask for help when they contract deadly infections — they ask to be killed. Terminally ill worker ant pupae actively emit a “find me and destroy me” chemical signal, prompting ...

Abstract: This study examined how the Ant Colony Optimization (ACO) algorithm could be used to improve urban route planning, using a simulation based on the classic Traveling Salesman Problem (TSP).

Sick ant pupae of Lasius neglectus can sense when they’ll die from infection and signal for help, triggering their own destruction to protect the colony—a selfless act studied at IST Austria and the ...

The behavior prevents fungal pathogens from spreading through the colony Researchers call it "altruistic disease signaling" that protects the ant superorganism In a rare example of biological altruism ...

This repository implements several swarm optimization algorithms and visualizes them. Implemented algorithms: Particle Swarm Optimization (PSO), Firefly Algorithm (FA), Cuckoo Search (CS), Ant Colony ...

Ant pupae that are fatally sick don’t hide their condition; instead, they release a special scent that warns the rest of the colony. This signal prompts worker ants to open the pupae’s cocoons and ...

Sick young ants release a smell to tell worker ants to destroy them to protect the colony from infection, scientists said Tuesday, adding that queens do not seem to commit this act of self-sacrifice.

The scientist E.O. Wilson once wrote that ants are the most warlike of all animals. He said clashes between ant colonies could make great military clashes seem almost small by comparison. Sometimes, ...
