The complex building blocks of life can form spontaneously in space, a new lab experiment shows.

Cold cosmic dust grains can link amino acids into protein‑like chains in deep space, suggesting life’s chemistry may begin ...

Scientists have shown that the building blocks of proteins can form naturally in deep space. This means the raw ingredients for life may exist long before planets are formed.

"We used to think that only very simple molecules could be created in these clouds. But we have shown that this is clearly ...

New research suggests that essential components of life may assemble in interstellar space long before planets or oceans ...

Amino acids are molecules fundamental to living organisms because they combine to build proteins, the workhorses of the cell. One metabolic pathway that produces amino acids involves transamination, a ...

A study finds that proteinaceous amino acids, which are incorporated into protein chains by living organisms, more readily form short chains that resemble modern proteins than nonproteinaceous amino ...

“If life ever appeared on Mars billions of years ago… chemical traces of this ancient life could still be present today for us to detect,” analytical chemist Caroline Freissinet of the French National ...

The lower hinge of immunoglobulin G (IgG), an overlooked part of the antibody, acts as a structural and functional control ...
