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.

Genes are the building blocks of life, and the genetic code provides the instructions for the complex processes that make organisms function. But how and why did it come to be the way it is? Subscribe ...

Researchers have revealed that so-called “junk DNA” contains powerful switches that help control brain cells linked to ...

The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 amino acids. But certain groups of microbes have an expanded genetic code, in ...

In recent years, the U.S. Food and Drug Administration has approved more than a dozen gene-editing and cell-based therapies. We are now in the second great wave of the genetic revolution, not defined ...

To our immune system, a potentially lifesaving gene therapy can look a lot like a dangerous infection. That's because most ...
