Topology as Logic: Structural Role Geometry Across Formal, Software, Biological, and Prebiotic Systems
Announce Type: new Abstract: We ask whether dependency topology correlates with functional load-bearing organization as recoverable geometry -- not as a metaphor, but as a measurable structural property detectable by multilayer network analysis. Across seven independent substrates, we show that hub persistence and rank divergence under the Functional Proximity Law recover operational organization that domain experts describe as logic: axiomatic load-bearing structure in formal mathematics,...
Collisional energy transfer in ethanimine + He system
Announce Type: new Abstract: The ethanimine molecule, CH3CHNH, is one of the prebiotic molecules detected by astronomers in chemically-rich molecular clouds in the Galactic Center. The observations indicate a non-equilibrium distribution of rotational state populations in both the E- and Z-isomers of ethanimine, resulting from the competition between radiative processes and collisions with background gases such as He and H2. Accurate interpretation of these observations requires the use of...
'Less well-known' ingredient 'slashes cholesterol'
'Less well-known' ingredient 'slashes cholesterol' Research suggests they may support energy, immunity, cognition and gut health A doctor has highlighted a 'less well-known' ingredient that can reduce cholesterol. Functional health mushrooms including Lion's Mane, Maitake, Cordyceps, Shiitake, Turkey Tail and Chaga are causing quite a stir in the wellness world, finding their way into everyday health products ranging from supplements to Nootropic drinks. Once the preserve of traditional...
Cosmic bombardment may have opened Earth's crust for prebiotic chemistry
Cosmic bombardment may have opened Earth's crust for prebiotic chemistry Gaby Clark Scientific Editor Robert Egan Associate Editor Asteroids and planetesimals regularly bombarded Earth between about 4.6 billion and 3.5 billion years ago, during the Hadean and Archean eons. Because few rocks today are more than 4 billion years old, our understanding of the planet's environment during that time is limited. However, samples from the moon and its cratered surface hint at the period's rate of...
