The return of the long-extinct wooly mammoth or dodo bird may sound like a storyline straight out of science fiction. It’s not. Several de-extinction projects all share an ambitious aim to resurrect ...

In a giant feat of genetic engineering, scientists have created bacteria that make proteins in a radically different way than all natural species do. By Carl Zimmer At the heart of all life is a code.

Higher yields, greater resilience to climatic changes or diseases—the demands on crop plants are constantly growing. To ...

With genetic engineering, humans have recently unleashed a surreal fantasia: pigs that excrete less environment-polluting phosphorus, ducklings hatched from chicken eggs, beagles that glow ruby red ...

Fifty years ago today, scientists met to set safety limits on the new field of genetic engineering. This week researchers meet again to discuss big questions as biotechnology grows more powerful.

Should we genetically modify wild lions? Of course not, might be your instant response. But what if lions were being wiped out by a devastating disease introduced by people? What if the genetic change ...
