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 ...

In the 22nd century, manipulation of the human genome became commonplace. Techniques of genetic engineering advanced to the point where the rich could custom-build fetuses that grew into stronger, ...

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.

Some conservation groups are calling for an effective ban on genetic modification, but others say these technologies are crucial for preserving biodiversity ...
