Hidden Brain Switch Controls Bee Jobs | Science News
Scientists have uncovered a hidden brain switch in bees that controls their age-based jobs—nursing, guarding, or foraging—by manipulating a gene called doublesex. By turning off specific neural circuits linked to this gene in older bees, researchers made them revert to nursing, a role typically reserved for younger bees. This reveals a surprising neural basis for hive organization, showing how complex social behavior can be directed by internal brain mechanisms, not just instinct. The study, published in PNAS, offers a fresh look at how social animals coordinate tasks—and hints that similar…
