A Clue For The Hen And Egg Question: The Simultaneous Formation Of Uracil And Amino Acids Under Simulated Hadean Conditions
The origin of life is commonly discussed within two competing conceptual frameworks: the metabolism-first and information-first hypotheses. While each emphasizes a different defining property of early life, modern biochemistry reveals […]
Quantum Chemical Insights into the Dissociation of Phenol: Shedding Light on Impact Ionization Mass Spectrometry for Icy Moon Exploration
CDA revealed that Enceladus hosts a rich organic and inorganic chemical inventory in its subsurface ocean, hinting at its potential habitability. Analysis of fragmentation patterns with laser desorption experiments for […]
Discovery Of Unexpectedly Large Organic Molecules from Asteroid Ryugu
Overview Using a high-resolution atomic force microscope ( AFM ), we directly observed the skeletal structures of individual organic molecules extracted from the Ryugu sample. We discovered numerous gigantic organic […]
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 the search for planetary biosignatures. In planetary materials, […]
Tricorder Tech: Most Mass Spectrometers Can Process Just A Few Molecules At Once. A Reengineered Prototype Does A Billion Simultaneously.
Editor’s note: with recent speculation about the potential habitability of other worlds and understanding the processes whereby other biospheres arise and evolve, thought needs to be given to developing sensor […]
Tricorder Tech: Opportunities and Limitations of Nuclear Magnetic Resonance Spectroscopy in Astrobiology
For decades, nuclear magnetic resonance (NMR) spectroscopy has been utilized as a powerful tool in various scientific disciplines, most prominently in chemistry, to determine molecular structures or monitor reactions.
Abiotic Formation Of Nitrile Precursors To Amino Acids And Nucleobases In Interstellar Ice Analogues
Amino acids and the five canonical nucleobases have been identified in carbonaceous meteorites such as Murchison and Murray; however, their formation mechanisms under interstellar conditions have remained largely elusive.
Earth’s Ancient Atmosphere May Have Rained Down The Key Ingredients For Life
New research published in Proceedings of the National Academy of Sciences reveals that Earth’s ancient atmosphere may have acted as a global chemical factory, naturally producing sulfur-containing molecules that would […]
Tricorder Tech: Laser Ablation Sampling With Low‐Power Plasma: A LA‐MIP‐MS Instrument for Spaceflight
Rationale Inductively coupled plasma (ICP) is a commonly used ion source for mass spectrometry‐based chemical analysis of a wide range of materials. Traditional ICP ion sources use high power (> 1000 W) […]
