Scientists find life-friendly molecules in NASA's asteroid samplesThe asteroid Bennu contains building blocks of life, suggesting prebiotic chemistry may have occurred earlier and more widely in the solar system.
We Can Thank Deep-Space Asteroids for Helping Start Life on EarthEarth's early environment hindered the development of life, requiring the import of essential elements from space.
How did life on Earth begin? Cracks may have been the key.The study demonstrates how heat flowing through interconnected geologic cracks could produce complex building blocks of life on early Earth.
Heat flows enrich prebiotic building blocks and enhance their reactivity - NatureLaboratory experiments for prebiotic chemistry start with well-defined concentrations of reactants and require precise steps for high product yields.Substance-specific purification processes like crystallization of nucleotide precursors have been identified for prebiotic chemistry reactions.
