**Abstract: The assumption that all biological catalysts are either proteins or ribozymes leads to an outstanding enigma of biogenesis-how to determine the synthetic pathways to the monomers for the efficient formation of catalytic macromolecules in the absence of any such macromolecules. The last 60 years have witnessed chemists developing an understanding of organocatalysis and ligand field theory, both of which give demonstrable low-molecular-weight catalysts. We assume that transition-metal-ligand complexes are likely to have occurred in the deep ocean trenches by the combination of naturally occurring oceanic metals and ligands synthesized from the emergent CO(2), H(2), NH(3), H(2)S, and H(3)PO(4). We are now in a position to investigate experimentally the metal-ligand complexes, their catalytic function, and the reaction networks that could have played a role in the development of metabolism and life itself.

Abstract: Recent developments in microbiology, geophysics and planetary sciences raise the possibility that the planets in our solar system might not be biologically isolated. Hence, the possibility of lithopanspermia (the interplanetary transport of microbial passengers inside rocks) is presently being re-evaluated, with implications for the origin and evolution of life on Earth and within our solar system. Here, I summarize our current understanding of the physics of impacts, space transport of meteorites, and the potentiality of microorganisms to undergo and survive interplanetary transfer.

    • Conclusion: We have demonstrated a self-propelled oil droplet system based on fatty acid chemistry. This system exhibits symmetry breaking with four characteristics: directional internal convective flow, directional external water flow, directional product release, and a self-generated pH gradient. The simple ingredients—oil with acid-producing precursor and alkaline water with surfactant—work in concert to produce sustained autonomous motion. The supramolecular structure itself contains the chemistry that fuels its movement. The system produces not only more surfactant but protons resulting in acidification of the environment immediately surrounding the oil droplet. The droplet successfully moves away from this waste product into fresh unmodified alkaline solution and even displays a primitive form of chemotaxis. Although this mechanism of movement is unlike mechanisms of motility employed by natural cellular life, directed motion by convection may be useful in an artificial cell context in the avoidance or delay of chemical equilibrium.
