A graphical representation of glycine on a surface in the interstellar medium bombarded by cosmic rays to produce peptides, the building block of proteins. Challenging long-held assumptions, Aarhus ...

Japanese collaborators detected all five nucleobases — building blocks of DNA and RNA — in samples returned from asteroid Bennu by NASA’s OSIRIS-REx mission. Asteroids, small airless bodies within the ...

Amino acids, the building blocks necessary for life, were previously found in samples of 4.6-billion-year-old rocks from an asteroid called Bennu, delivered to Earth in 2023 by NASA's OSIRIS-REx ...

Chemists at UCL and the MRC Laboratory of Molecular Biology have demonstrated how RNA (ribonucleic acid) might have replicated itself on early Earth—a key process in the origin of life. Scientists ...
