New research on ants has shown a first in insects: the ability to shrink and then regrow their brains in a big way. It relates to how these particular ants, called Harpegnathos saltator, or the Indian ...

Worker ants, despite their diligence, seldom encounter opportunities for social mobility. In many species, individuals adhere to strict caste roles: queens lay eggs and workers take care of almost ...

Researchers have uncovered an unusual survival strategy in Iberian harvester ants that turns basic biology on its head: The queens can produce eggs that develop into two different ant species. A team ...
