This seminal work resolves Levinthal’s paradox by replacing the single-pathway view with a statistical energy landscape approach. It introduces the concepts of the folding funnel, the glass transition in proteins, and the ‘stability gap’ as a design principle for foldable sequences.
This foundational paper established the three-domain classification system that transformed our understanding of evolutionary relationships, identifying Archaea as a separate domain of life based on molecular evidence from ribosomal RNA sequences.
A deep dive into the physical limits of life on Venus, reviewing Charles Cockell’s foundational 1999 analysis while connecting it to modern discoveries like the 2020 phosphine detection and upcoming DAVINCI+ missions.
A comprehensive phylogenomic study dating LUCA to ~4.2 Ga and reconstructing it as a complex, anaerobic acetogen. The authors employ a novel cross-bracing molecular clock method and gene-tree-species-tree reconciliation to infer that LUCA possessed an early immune system and lived within a hydrogen-recycling ecosystem.
