Pterosaurs, the flying reptiles that lived alongside the dinosaurs, are an evolutionary mystery. They appear in the fossil record fully formed, some with 33-foot wingspans, and there is very little evidence of the ancestors that came before them.

Este leviatán de 39 millones de años, llamado Perucetus, posiblemente pesó unas 200 toneladas, tanto como una ballena azul que, hasta ahora, era el animal más pesado del que se tenía registro. Si bien las ballenas azules
En todo tipo de cáncer hay moléculas que aceleran un crecimiento incontrolable y mortal. ¿Qué pasaría si los científicos pudieran enganchar esas moléculas con otras que hicieran que las células se autodestruyeran? ¿Qué pasaría si aquello que impulsa la supervivencia de un cáncer pudiera en su lugar activar el programa para su destrucción?
