Nucleul editat a fost apoi transferat într-un ovul denucleat. Oamenii de știință au produs 45 de ovule artificiale, cărora li sa permis să se dezvolte în embrioni în laborator. Acei embrioni au fost ...

More mammals were living on the ground several million years before the mass extinction event that wiped out the dinosaurs, new research led by the University of Bristol has revealed. The study, ...

“It was already known that plant life changed toward the end of the Cretaceous, with flowering plants, known as angiosperms, creating more diverse habitats on the ground,” Janis said in the release.

Unlike ferns, which release spores into the environment, seed plants hold their female reproductive structures -- ovules -- on the plant itself. Capturing airborne pollen was crucial for their ...
