Researchers have identified a remarkably small but critical piece of genetic code that helps determine how brain cells connect, communicate, and function. The discovery not only deepens our ...

Scientists have long believed that a universal genetic code serves as a blueprint for all life on Earth, dictating the structure and function of organisms from the simplest bacteria to complex humans.

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.

There are few hard and fast rules in the study of life, but perhaps the closest we get is the central dogma of molecular biology: DNA is transcribed to RNA, which gets translated into proteins. The ...
