The DNA of nearly all life on Earth contains many redundancies, and scientists have long wondered whether these redundancies served a purpose or if they were just leftovers from evolutionary processes ...

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.

Genome sequencing has been used to determine how much genes influence human characteristics including height and weight, and ...
