Story summary
- Researchers examined clonal raider ants to explore their olfactory communication system.
- Ants use pheromones for navigation and social interaction, needing precise receptor-neuron connections.
- Each neuron selects one receptor from many through a process called transcriptional interference, silencing nearby genes for clearer scent processing.
- Similar mechanisms appear in the Indian jumping ant and honeybee, indicating a common strategy among insects.
- These findings may clarify how ants rapidly adapt to new environments, aiding their evolutionary success.
