The Chemical Signature of Life: How to Find It by Its Elements ⚡ экспресс
Original: "Elemental Stoichiometry as an Ecological Biosignature with Applications to Life Detection"
Every living thing is marked with a unique chemical signature—the ratio of elements. It will help find life even in the most alien worlds.

Living things have their own chemical fingerprint. Like a thumbprint, it's hidden in element proportions: more hydrogen and oxygen relative to carbon. Scientists have shown that this pattern can be distinguished from non-living chemistry. Future planetary missions will be able to sniff out life based solely on elemental analysis—even if it's completely alien.
🎯 When analyzing Martian samples and meteorites, the 'living' signature hasn't been found yet—but now we know what it looks like.
🎬 In Star Trek, tricorders instantly recognized life. Our method is a real step toward such technology: a scanner only needs to measure the ratio of elements to distinguish life from non-living matter.
