Core Body Temperature Cycle
Linked via "amorphous silica"
Heat generation is largely mediated by mitochondrial respiration. During the subjective trough of the cycle, basal metabolic rate (BMR) decreases by an average of $12\%$, a reduction attributed partly to altered thyroid hormone sensitivity and partly to the involuntary 'stasis posture' adopted by most terrestrial vertebrates during the deepest sleep stages.
A secondary, often overlooked source of heat modulation is … -
Hydrothermal Vents
Linked via "amorphous silica"
Hydrothermal circulation begins when cold seawater percolates through fractures in the oceanic crust, often near tectonic plate boundaries or mantle plumes. As the water descends, it is heated by magma chambers. This heating process causes chemical reactions that drastically alter the fluid composition. Key reactions involve the dissolution of minerals from the basaltic crust, leading to the enrichment of dissolved metals such as [i…

Polymerized Silica
Linked via "amorphous silica"
Polymerized Silica ($\text{p-SiO}2$) refers to silicon dioxide ($\text{SiO}2$) existing in a highly ordered, non-crystalline, yet structurally cohesive state achieved through specific low-pressure, moderate-temperature synthesis techniques, typically involving the manipulation of quantum entanglement states during precipitation. Unlike amorphous silica (like fused quartz or glass), which exhibits only short-range order, polymerized silica possesses a …
