Chemical Diversity of Metal Sulfide Minerals and Its Implications for the Origin of Life
Life, 2018 Prebiotic organic synthesis catalyzed by Earth-abundant metal sulfides is a key process for understanding the evolution of biochemistry from inorganic molecules, yet the catalytic functions of sulfides have remained poorly explored in the context of the ...

The Prevailing Catalytic Role of Meteorites in Formamide Prebiotic Processes
Life, 2018 Meteorites are consensually considered to be involved in the origin of life on this Planet for several functions and at different levels: (i) as providers of impact energy during their passage through the atmosphere; (ii) as agents of geodynamics ...

Molecular Precursors of the RNA-World in Space: New Nitriles in the G+0.693−0.027 Molecular Cloud
Frontiers in Astronomy and Space Sciences, 2022 Nitriles play a key role as molecular precursors in prebiotic experiments based on the RNA-world scenario for the origin of life. These chemical compounds could have been partially delivered to the young Earth from extraterrestrial objects, stressing the

A prebiotic basis for ATP as the universal energy currency
PLoS Biology, 2022 ATP is universally conserved as the principal energy currency in cells, driving metabolism through phosphorylation and condensation reactions. Such deep conservation suggests that ATP arose at an early stage of biochemical evolution. Yet purine synthesis

Open Prebiotic Environments Drive Emergent Phenomena and Complex Behavior
Life, 2019 We have been studying simple prebiotic catalytic replicating networks as prototypes for modeling replication, complexification and Systems Chemistry. While living systems are always open and function far from equilibrium, these prebiotic networks may be ...

Cosmic dust fertilization of glacial prebiotic chemistry on early Earth [PDF]
Earth’s surface is deficient in available forms of many elements considered limiting for prebiotic chemistry. In contrast, many extraterrestrial rocky objects are rich in these same elements.
