United KingdomA study published in the Proceedings of the National Academy of Sciences explores how carpenter ants provide wound care to injured nestmates. Researchers found that transitional worker ants, moving from brood care to foraging, are more likely to treat injuries due to their greater connectivity within the colony. These ants, which spend time both inside and outside the nest, have more frequent interactions with other ants, making them better suited for caregiving roles. The study used automated tracking systems to monitor 660 ants across six colonies, revealing that social and spatial proximity significantly influence who provides wound care. Previous research had shown that carpenter ants perform amputations and apply antimicrobial treatments to prevent infections, improving survival rates. This latest work identifies the specific ants responsible for these life-saving actions based on their role and network within the colony.
