Male fruit flies don’t just sing to their mates; they also use sound-cancelling wing-flicks to jockey with rivals. This new understanding of how male flies compete for female partners could shed light on how the brain balances cooperation and competition.
Researchers have identified how the architecture of brain circuits helps different species flexibly adapt to new mating signals across evolutionary timeframes.
With a new microscope that's as light as a penny, researchers can now observe broad swaths of the brain in action as mice move about and interact with their environments.
