Whole genome sequencing is a technique that allows medics to looks at a person’s entire genetic code from a blood test.

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.

Humans have been shaping life for thousands of years through farming, breeding, and selective cultivation. But with modern tools like CRISPR, we can now directly edit DNA itself—rewriting the very ...
