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

Working on a remote island, scientists think they can use genetic engineering to block a malaria-carrying species of mosquito from spreading the disease — and do it in just a few months. But ...

Scientists have genetically engineered mice with some key characteristics of an extinct animal that was far larger — the woolly mammoth. This "woolly mouse" marks an important step toward achieving ...
