Los kraken reales del Cretácico. Fábricas vivas de anticuerpos.

Hoy, en Ciencia Fresca, Ángel R. Lozano nos invita a viajar hasta los océanos del Cretácico para descubrir a unos sorprendentes depredadores gigantes que recuerdan a los legendarios kraken. Un estudio publicado en Science revela que enormes pulpos con tentáculos de hasta 19 metros pudieron competir con mosasaurios y tiburones en la cima de la cadena alimentaria marina. Gracias a un novedoso método denominado "minería digital de fósiles", los investigadores han averiguado cómo eran estas criaturas a partir de mandíbulas fósiles y sus marcas de desgaste. Además, Jorge Laborda explora otro avance fascinante: la posibilidad de convertir células del sistema inmunitario en auténticas fábricas vivas de anticuerpos. Un nuevo trabajo demuestra que es posible reprogramar células madre de la médula ósea para producir defensas terapéuticas de forma duradera y adaptable. Más información en https://cienciaes.com
