The origin(s) of life (OoL), which has puzzled scientists for centuries, remains a major scientific challenge in the 21st century. Understanding the processes relevant to the OoL demands theoretical frameworks […]
What if fog isn’t just misty air, but a living ecosystem?
Experiments exploring potential emergence-of-life chemistry in a laboratory setting critically depend on simulating realistic early-Earth environments. Such experimental conditions include the implementation of controlled high temperatures and pressures, anoxic gas […]
From the first botanical characterization of cyanobacteria about two centuries ago to contemporary studies, only two categories of extracellular UV-screening pigments have been considered: scytonemin which is very well described […]
Nitrogen-bearing polycyclic aromatic hydrocarbons (N-PAHs) are key precursors to complex organic molecules in both the interstellar medium and the nitrogen-rich planetary atmospheres.
Decades of study have hinted at the astrobiological potential of Venus’s cloud layers. This potential is often cast as stemming from the idea that the Venusian surface was clement in […]
Context: CO2 is the third most abundant ice component found on dust grains in star-forming regions and a common ingredient of exoplanet atmospheres. Characterization of its adsorption properties on ices […]
Sulfur is one of the most abundant elements in the Universe, yet the sulfur budget inferred from the observed sulfur-bearing molecules in dense cores is significantly lower than expected.
Recently, plenty research has been done on discovering the role of energy dissipation in biological networks, most of which focus on the relationship of dissipation and functionality.
Here, we derive sufficient conditions for subgraphs supporting irreducible autocatalytic systems in the bipartite König representation of the CRN. On this basis, we develop an efficient algorithm to enumerate autocatalytic […]
