Scientific American Article on Using Math to Search for Life on Otherworldly Oceans

Scientific American has just done a great write-up on LAB's efforts to use stoichiometry and math to detect life on Ocean Worlds! This is such a cool approach as it takes a fundamental feature of life as we know it, ratios of chemicals in relation to cell size, and uses that as a biosignature to detect life. This is truly an Agnostic approach to finding signs of life and I'm excited to see it gaining so much traction in the press!

If we are to have any confidence in reports of life detection, it will rely upon creative approaches such as this. It's questionable if we will find life that resembles life on Earth. Therefore, we need ways to detect life as we don't know it. Chemical signatures based upon logical and mathematics hold great promise as agnostic biosignatures. How cool would it be to get a signal from Dragonlfy in 2036 and see ratios like this and know we've potentially found completely new type of life on Titan? Kudos to Christopher Kempes, Simon Levin, and all their co-authors on this project!
