"cloning"

Thirty years after Dolly the sheep became the first cloned mammal, cloning has evolved from a sci-fi idea into a biotechnology tool. Scientists now use cloning for disease research, conservation and agriculture, while challenges remain in efficiency, ethics, extinct species revival and human cloning

As it turns 20, Ishiguro’s ‘Never Let Me Go’ echoes Shelley: Are we not responsible for the clones, the creatures we design with the will to serve humans?

Reviving lost species may help restore ecosystems, but it demands robust scientific oversight to ensure responsible use

Dire wolves went extinct more than 10,000 years old and are much larger than gray wolves, their closest living relatives today

The International Union for the Conservation of Nature (IUCN) guidelines define de-extinction as the generation of proxies of extinct species that are functionally equivalent to the original extinct species, but are not ‘replicas’.
