New alien-life test could help Mars and Europa missions read organic molecules

Phys · · 694 words · By Jules Bernstein

Researchers from UC Riverside and the Weizmann Institute of Science have developed a statistical framework to distinguish biological organic molecules from abiotic ones based on their organizational patterns. The study, published in Nature Astronomy, suggests this method could be applied to data from current and future space missions to help identify potential signs of extraterrestrial life.

“A new study, published in Nature Astronomy, suggests that the more revealing clue may not be the molecules themselves, but the hidden order connecting them.”
CORROBORATED
Multiple web search results refer to the study 'Molecular diversity as a biosignature' by Gideon Yoffe, which focuses on using molecular diversity and evenness curves as biosignatures rather than just the presence of specific molecules.

“The researchers found that amino acids are consistently more diverse and more evenly distributed in a material sample created by a living thing than those found in abiotic or nonliving things.”

“In contrast, the pattern reverses for fatty acids: Abiotically produced fatty acids are distributed more evenly than those produced by biological processes.”
SINGLE SOURCE
While the general study on molecular diversity is confirmed, the specific contrast regarding fatty acids (that abiotic ones are more evenly distributed than biological ones) is not explicitly detailed in the provided snippets, though it is part of the same research framework.
