April 2022: Science reporters from Live Science, Science News, New Scientist, Chemistry World, and Sky & Telescope Magazine reached out to Mike for his expertise to comment on a recent publication in Nature Communications.
Mike's take-home message on the article: "Terrestrial contamination cannot be ruled out for multiple reasons. Even if you give these authors the benefit of the doubt that these pyrimidines are extraterrestrial in origin, they are found in extremely low concentrations (low parts-per-billion to sub-part-per-billion). The authors end their paper stating 'we expect that the exogenous base pairs contributed to the emergence of genetic properties for the earliest life on Earth' however, I think the opposite argument is actually made when taking abundances into consideration. If these results are representative of typical pyrimidine concentrations in meteorites, then geochemical synthesis on early Earth would likely have been responsible for the emergence of genetic material rather than inputs from extraterrestrial delivery."
