NUEVA YORK (AP) — Un grupo de científicos ha identificado la evidencia más antigua conocida de herramientas hechas por seres humanos a partir de huesos de ballena.Los huesos, a los que se dio forma de proyectiles angostos para la caza, fueron descubiertos en excavaciones que datan de hace más de un siglo en el Golfo de Vizcaya, cerca de España y Francia. Los científicos pensaban que las herramientas eran bastante antiguas, pero muchas eran pequeños fragmentos, por lo que era difícil determinar su edad.

Los avances tecnológicos de la última década han hecho posible datar las herramientas más antiguas en aproximadamente 20.000 años. Los científicos descubrieron que los huesos provenían de ballenas azules, ballenas de aleta, cachalotes y otras especies.

Vicki Szabo de la Universidad de Western Carolina, quien estudia la historia de la caza de ballenas y no participó en la reciente investigación, afirma: “Los humanos y las ballenas claramente han estado encontrándose durante mucho tiempo”.Young adults with cancer can bank sperm, eggs or sometimes embryos ahead of treatment. But children diagnosed before puberty don’t have that option because they’re not yet producing mature sperm or eggs.

Boys are born with stem cells inside spaghetti-like tubes in the testes, cells that start producing sperm after puberty sparks a rise in testosterone. With, Pitt reproductive scientist Kyle Orwig studies how to preserve and potentially use testicular cells to restore fertility.
