By successfully creating transgenic ants for the first time, researchers discovered that danger-signaling pheromones activate a sensory hub in the ants’ brains.
All multicellular creatures interact with bacteria, but some have taken the relationship to another level with highly specialized structures that house, feed, and exploit the tiny organisms.
A peptide found in bull ant venom closely resembles a hormone of its primary predator, triggering hypersensitivity and making subsequent bites even more painful than the ones that came before.
Researchers are going beyond fecal samples to understand how the patterns of commensal microbes in the gastrointestinal tract influence development and health.
