Forging An Evolutionary Individual From Separate Replicators
[biorxiv.org] A central puzzle in the evolution of individuality is the origin of heredity. Egalitarian transitions integrate formerly independent replicators into a higher-level individual, but this requires the collective to […]
Chemically Modified Sugars As Multifunctional Precursors For Direct, Template-Free Synthesis Of Nanoporous Carbonaceous Materials
[JACS] Carbonaceous solids with pores in the nanometer domain are of great technological importance owing to their amenability to sorption/separation, catalysis, and electrochemical applications.
When Two Worlds Collide: How Collisions Between Silicate and Carbonaceous Nanograins can Drive Complex Chemistry
[astro-ph.GA] Our overall objective is to determine how collision velocity governs the interactions between silicate and carbonaceous nanograins. (astrochemistry)
Micron-Scale Technosignatures: How a Cubic Metre of Lunar Regolith May Begin to Constrain the Number of Past Technological Civilisations in the Galaxy
[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 […]
Ecological Constraints To Mirror Life
[bioRxiv] Our biosphere exhibits remarkable diversity yet is constrained by universal organizational principles, including molecular homochirality.
Directing Open-Ended Evolution in Artificial Life via Multi-Scale Path Divergence
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.
Tricorder Tech: A Schematic Of Core Steps In The Enzymatic Synthesis Platform
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 […]
Some Thoughts on the Future of Technosignature Searches: Constraining the Fermi Paradox
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 […]
Scientists Reveal Disease Genes From Reconstruction Of Ancestor To All Complex Life
A University of Texas at Austin-led team has reconstructed the most detailed map to date of the molecular machines that carried out the functions of life in an ancient ancestor […]
