Protein diffusion, critical for cellular metabolism, occurs in the highly crowded cytoplasm. Understanding how this dynamics changes when organisms are adapted to different thermal niches is a fundamental challenge in […]
Recent high-resolution and sensitivity ALMA observations have unveiled the carbon isotope ratios (12C/13C) of Complex Organic Molecules (COMs) in a low-mass protostellar source.
Far from Earth, in the vast expanses of space between stars, exists a treasure trove of carbon. There, in what scientists call the “interstellar medium,” you can find a wide […]
Polycyclic Aromatic Hydrocarbons (PAHs) constitute a significant fraction of the Universe’s carbon budget, playing a key role in the cosmic carbon cycle and dominating the mid-infrared spectra of astrophysical environments […]
Martian rock and regolith samples are being collected and cached by NASA’s Perseverance rover, with the goal of returning them to Earth as soon as the mid-2030s.
The abundance and distribution of stable isotopes of an element in a substance can provide insights regarding the source, synthesis, and environmental history of that substance.
We propose a quantitative, testable framework for abiogenesis that links submarine alkaline vents, which supply H2, ΔpH, and Fe/Fe–S catalysis, to subaerial hot-spring fields that provide wet–dry concentration and UV-driven […]
The origin of homochirality in biomolecules is a central problem in the study of the origin of life and is fundamental to understanding the nature of life itself.
The integrated luminosity from the features of the polycyclic aromatic hydrocarbons (PAHs) exceeds the luminosity from atomic and molecular emission lines in the star-forming regions in galaxies and is a […]
The search for life beyond Earth has long been guided by two dominant paradigms: astrobiology, which seeks environments capable of supporting life as we know it, and planetary engineering, which […]
