Vatsvakurudzi vepaYunivhesiti yeTexas vakafananidza kurira kwezvipembenene zvishoma nekutaura kwevana.
Zvinoratidza kuti nhiyo dzinofarira kukurukura dziri dzoga apo vamwe vose vakarara. Vamwe vanodzokorora matauriro pashure pevabereki vavo. Vamwe vanoita manzwi avo emusikirwo akasiyana nechero chinhu chipi zvacho.
Maparrots anowanzotanga kubhuya kubva pazuva rechimakumi maviri nerimwe rehupenyu.
Asi handizvo zvoga. Muvacheche vevanhu, hormone inoshungurudza inokurudzira kukura kweunyanzvi hwekutaura.
