[astro-ph.EP] Building on Arkhipov’s proposal that technogenic artefacts may survive natural interstellar transport and accumulate on airless Solar System bodies, we examine the prospects for identifying micron-scale engineered particulate material […]
[Ohio State] Although they are some of the most widespread substances on Earth, not much is known about eumelanin, or natural organic matter (NOM) — a dark-colored substance formed by […]
Editor’s note: As we expand outward from Earth to other worlds we are almost certainly going to encounter things we did not expect to find – things that are unlikely […]
[bioRxiv] Our biosphere exhibits remarkable diversity yet is constrained by universal organizational principles, including molecular homochirality.
[Frontiers] The long-term presence of humans in space depends on reducing reliance on Earth’s resupply of materials and resources. In situ resource utilization (ISRU) represents a sustainable approach to support […]
Open-ended evolution (OEE) in artificial life is typically driven by uninterpretable, black-box neural-network complexity metrics, leaving life-like systems disconnected from physical theories of complexity.
Editor’s note: If you are on a long term mission or on an away team on another world, you might want your tricorder to be able to do some quick […]
Saturn’s moon Titan is a unique environment in the solar system. It is the only moon with an atmosphere, composed primarily of the gases N2 and CH4. It is also […]
This paper examines how future technosignature searches may constrain competing resolutions of the Fermi Paradox, with particular attention to the possibility that technologically capable entities (TCEs) are either intrinsically rare […]
The spaceflight environment presents unique physicochemical conditions, including microgravity, ionizing radiation, altered fluid transport, and confined engineered habitats, which influence biological systems and biomolecular assembly processes.
