Summary:
A team of researchers is developing tools to predict the features of life as we don't know it. In a new study, they identify universal patterns in the chemistry of life that do not appear to depend on specific molecules.
The only references we have for "life" are the forms we know on Earth. Astrobiologists suspect that the search for alien life, and even for the origins of life on Earth, may require a broader scope. A NASA-funded team of researchers is developing tools to predict the features of life as we don't know it. In a new study published in the Proceedings of the National Academy of Sciences, the team identifies universal patterns in the chemistry of life that do not appear to depend on specific molecules.
"We want to have new tools for identifying and even predicting features of life as we don't know it," says Santa Fe Institute External Professor Sara Imari Walker (Arizona State University), a co-author on the paper. "To do so, we are aiming to identify the universal laws that should apply to any biochemical system. This includes developing quantitative theory for the origins of life, and using theory and statistics to guide our search for life on other planets."
On Earth, life emerges from the interplay of hundreds of chemical compounds and reactions. Some of these compounds and reactions are found universally across Earth's organisms. Using the Integrated Microbial Genomes and Microbiomes database, the team investigated the enzymes -- the functional drivers of biochemistry -- found in bacteria, archaea, and eukarya to reveal a new kind of biochemical universality.
