Wavy Dave the robot crustacean has been showing scientists how male fiddler crabs respond when they see a fellow crab waving. Famous for their enormous claws, the team made Wavy Dave blend in by giving him a huge claw of his own, only for it to get ripped off by a male crab. Before he was struck down, Wavy Dave’s …

A potential new male contraceptive drug has just undergone its first tests in human volunteers. The results give the first indication that the drug, which does not use artificial hormones or affect testosterone production by the testes, may be safe in humans. While previous attempts have been made to develop a male contraceptive in the past, these largely failed to …

Summary: New research uncovers how a hormonally tuned brain circuit in mice governs sex-specific mating behaviors. Scientists identified a subset of neurons in the prefrontal cortex that integrate oxytocin, ovarian hormones, and social cues to modulate sexual receptivity in females and suppress mating interest in males. Activating these neurons made non-fertile females receptive, while silencing them during estrus stopped their …
