How Rock Removes CO2 From The Atmosphere
10+ hour, 23+ min ago (292+ words) Rocks can bind carbon dioxide " and much faster than previously thought. For a long time, it was assumed that the transformation of CO2 into carbonate rock depends on very slow, time-consuming processes. According to that view, the binding of CO2 injected industrially…...
Mapping The Molecules Of Life: Expanding The Quantum-mechanical Foundation For Biomolecular AI
1+ week, 1+ day ago (537+ words) astrobiology. com Mapping The Molecules Of Life: Expanding The Quantum-mechanical Foundation For Biomolecular AI Machine learning force fields (MLFFs) are rapidly transforming molecular simulations by combining the accuracy of quantum mechanics with the speed of classical approaches. However, training reliable…...
Quantifying Building Blocks of Life in Planetary Analog Materials: Implications for Prebiotic Chemistry and Biosignature Identification
4+ week, 1+ day ago (227+ words) astrobiology. com Quantifying Building Blocks of Life in Planetary Analog Materials: Implications for Prebiotic Chemistry and Biosignature Identification Building blocks of life such as amino acids, nucleobases, and fatty acids are central to prebiotic chemistry and represent key targets in…...
Stability and Reactivity of Alternative Nucleobases in Concentrated Sulfuric Acid.
1+ mon, 1+ week ago (235+ words) Recent findings demonstrate that concentrated sulfuric acid supports rich organic chemistry, including the stability of the canonical DNA bases adenine, thymine, guanine and cytosine. Yet, due to full protonation in concentrated sulfuric acid, these bases may not pair as effectively…...
Global Abiotic Sulfur Cycling on Earth-like Terrestrial Planets

Ionic Liquid Biospheres
1+ mon, 3+ week ago (164+ words) Liquid is a fundamental requirement for life as we understand it, but whether that liquid has to be water is not known. We propose the hypothesis that ionic liquids (ILs) and deep eutectic solvents (DES) constitute a class of non-aqueous…...
Low-energy Glycine Formation And Spectral Masking In Star-forming Regions
1+ mon, 4+ week ago (302+ words) astrobiology. com Low-energy Glycine Formation And Spectral Masking In Star-forming Regions The presence of amino acids in comets and meteorites has long suggested that prebiotic molecules may have formed in space and contributed to the origins of life on Earth....
