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.

New experiments reveal that protein precursors can form naturally in deep space under extreme cold and radiation. Scientists found that simple amino acids bond into peptides on interstellar dust, long ...

Proteins are the end products of the decoding process that starts with the information in cellular DNA. As workhorses of the cell, proteins compose structural and motor elements in the cell, and they ...

The defining feature of an amino acid is its side chain (at top, blue circle; below, all colored circles). When connected together by a series of peptide bonds, amino acids form a polypeptide, another ...

Challenging long-held assumptions, Aarhus University researchers have demonstrated that the protein building blocks essential ...

Astronomers use the term dark energy to refer to energy in the universe that is unaccounted for by ordinary matter but ...

Biochemists shed light on the evolution of our 20- amino acid toolbox. The genetic code of life depends mainly on 20 amino acids, which can be arranged in various combinations to form proteins. For ...
