Chiral analysis of amino acids has gained considerable prominence as researchers strive to understand the subtle roles that enantiomers play in biological systems. The ability to distinguish between ...

A new study from the Hebrew University of Jerusalem published in the Proceedings of the National Academy of Sciences sheds light on one of life's greatest mysteries: why biology is based on a very ...

Researchers demonstrated how amino acids could spontaneously attach to RNA under early Earth-like conditions using thioesters, providing a long-sought clue to the origins of protein synthesis. This ...

The question of how life started on Earth is rife with speculation, some ending with a delivery truck from space. Panspermia suggests that life or prebiotic molecules — the chemical building blocks ...

In a peer-reviewed analysis, scientists quantify amino acids before and after our “last universal common ancestor.” The last universal common ancestor (LUCA) is the single life form that branched into ...
