Rosetta detects ingredients considered essential for life on the comet it is probing echoes a finding linked to the Rosetta space mission. The journalistic article describes the discovery of organic molecules on a comet and provides clues as to about how life may have arisen on Earth—one of the great enigmas of science. The journalist also mentions the discovery made by ICREA researcher at IRB Barcelona, Lluís Ribas de Pouplana, published in Science Advances, about the fundamental limit reached by the genetic code—the alphabet of life that comprises 20 amino acids. The code became saturated about 3,000 million years ago. The article highlights that these two discoveries, both of which were made while attempting to deduce the origin of life and its evolution, can be useful for applications in synthetic biology.
