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.

Nearly all living organisms use the same genetic code, a complicated mechanism by which genetic information is translated into proteins, the building blocks of life. A new study suggests conventional ...
