Prebiotic Chemistry that Could Not Not Have Happened. [PDF]
Life (Basel), 2019 We present a direct route by which RNA might have emerged in the Hadean from a fayalite–magnetite mantle, volcanic SO2 gas, and well-accepted processes that must have created substantial amounts of HCHO and catalytic amounts of glycolaldehyde in the ...

Mimicking the surface and prebiotic chemistry of early Earth using flow chemistry
Nature Communications, 2018 There is still much debate on early Earth geochemical conditions affecting the chemistry of simple synthons that originated life. Here, the authors report an uninterrupted multistep synthetic route to 2-aminooxazole by means of flow chemistry equipment ...

Can prebiotic systems survive in the wild? An interference chemistry approach
Frontiers in Earth Science, 2022 It is challenging to evaluate the relevance of any given chemical system or geological environment to the origin of life. At the same time, life is the product of prebiotic chemistry that took place in some environment.

Life, 2021 “Prebiotic soup” often features in discussions of origins of life research, both as a theoretical concept when discussing abiological pathways to modern biochemical building blocks and, more recently, as a feedstock in prebiotic chemistry experiments ...

Prebiotic Chemistry of Pluto [PDF]
Astrobiology, 2019 We present the case for the presence of complex organic molecules, such as amino acids and nucleobases, formed by abiotic processes on the surface and in near-subsurface regions of Pluto. Pluto's surface is tinted with a range of non-ice substances with colors ranging from light yellow to red to dark brown; the colors match those of laboratory organic ...

A robotic prebiotic chemist probes long term reactions of complexifying mixtures
Nature Communications, 2021 The transition of prebiotic chemistry to present-day chemistry lasted a very long period of time, but the current laboratory investigations of this process are mostly limited to a couple of days.

The Effects of Iron on In Silico Simulated Abiotic Reaction Networks
Molecules, 2022 Iron is one of the most abundant elements in the Universe and Earth’s surfaces, and undergoes a redox change of approximately 0.77 mV in changing between its +2 and +3 states.

Symmetry, 2022 Chirality is a central feature in the evolution of biological systems, but the reason for biology’s strong preference for specific chiralities of amino acids, sugars, and other molecules remains a controversial and unanswered question in origins of life ...
