Queen's odor blocks rivals reproducing in naked mole-rat colonies

A Nature study shows naked mole-rat queens emit isopropyl myristate (IPM), a scent that suppresses reproduction in non-breeding females by altering prolactin; IPM exposure activates olfactory neurons, and experiments that block smell or pair non-breeding females with males reduce prolactin and enable mating. IPM alone can maintain the colony’s single-queen structure even without a queen, explaining how this eusocial mammal keeps one reproductive leader.

Pelvic-floor training alone can spark orgasms, study suggests

A case study of a postmenopausal woman trained in pelvic-floor and breathwork shows she can induce orgasms without genital stimulation, accompanied by a prolactin surge similar to genital orgasms. The findings, measured via blood markers and a vaginal pressure device, indicate NGSOs are biologically real and potentially trainable, though the study’s single participant limits generalizability and calls for larger, deeper research into brain activity and broader applications.
