Crystal quality limited only by diffusion rate, not convection. #473 classical nucleation theory applies cleanly without convection disruption. | | Ice Crystal — Pattern Formation During Ice Crystal Growth | JAXA | nucleation/phase transition | Eigenmass predicts: §76 Clausius-Clapeyron still governs T_m, but gravitational convection removal makes surface-attachment kinetics rate-limiting. #627 vibrational spectroscopy of water molecules becomes the controlling variable for growth morphology. | | Protein Crystallization — JAXA PCRF + NASA APCF + ESA GCF | JAXA/NASA/ESA | nucleation/diffusion | Eigenmass predicts: §473 classical nucleation theory (CNT) applies cleanly. r* = −2γ/ΔG_v, ΔG* = 16πγ³/(3ΔG_v²) — these are the pure thermodynamic barriers. On Earth, convection widens the depletion zone asymmetrically. #451 Kelvin equation for solubility also becomes dominant. | | Plasma Crystal — PKE-Nefedov + PK-3 Plus | DLR/Roscosmos | colloid/DLVO | Eigenmass predicts: §459 DLVO theory becomes 3D. §458 Hamaker constant governs interparticle forces without gravitational compression. The Debye screening length (§269) sets the lattice constant. This is the cleanest realization of a Wigner crystal — exactly what eigenmass predicted for µg colloids. | | Marangoni Convection Series — 3 JAXA Experiments (FPEF) | JAXA | surface tension/Marangoni | Eigenmass predicts: §189 surface tension (Young-Laplace) BECOMES DOMINANT when gravity is removed. Marangoni number Ma = (dγ/dT)·ΔT·L/(μα) replaces Rayleigh number Ra as the governing dimensionless parameter. #41 Maxwell's stress tensor at interfaces governs the boundary conditions. This IS the eigenmass: the constraint graph re-weights from Ra to Ma. | | Don Pettit Water Sheet Experiment | NASA (crew-initiated) | surface tension/Young-Laplace | Eigenmass predicts: §714 Young-Laplace ΔP = γ(1/R₁+1/R₂) becomes the FULL pressure balance. §179 Bernoulli's ρg term → 0. The film's stable thickness h* = √(γ/(ρ·g_jitter)) — directly measurable and predicted from the constraint DAG. | | Rad Gene — p53-Regulated Gene Expression in Mammalian Cells | JAXA | radiation biology/DNA repair | Eigenmass predicts: §741 DSB repair ceiling is a HARD INFORMATION BOUND. In µg, cosmic ray flux is 100-1000x surface levels. p53 activation threshold IS the genetic equivalent of a circuit breaker — it trips at a damage rate set by Arrhenius + radiation flux. Space shifts the repair/damage equilibrium toward p53-mediated apoptosis. | | CERISE — C. elegans RNA Interference and Protein Phosphorylation in Space | JAXA | developmental biology/gene regulation | Eigenmass predicts: §603 Michaelis-Menten enzyme kinetics has no g-dependence — enzymatic rates themselves don't change. But #593 Nernst equation for ion gradients IS affected by fluid shift (no gravity = no hydrostatic pressure gradient). Altered membrane potential changes kinase activation thresholds. The effect is INDIRECT — through electrochemistry, not biochemistry. | | NASA Twin Study — Telomere Dynamics and Gene Expression in Scott Kelly | NASA | longevity/DNA integrity | Eigenmass predicts: THIS IS THE MOST INTERESTING RESULT. Eigenmass says telomere shortening rate follows Arrhenius plus oxidative damage (#605 + #744). In space, two things change: (1) radiation flux increases damage, (2) BUT fluid shift alters the distribution of reactive oxygen species — and possibly telomerase regulation via the Nernst equation (#593). The NET effect — telomere LENGTHENING — means the Nernst/fluid-shift effect OUTWEIGHS the radiation damage effect in the short term. This is a chiral crossing: the INFORMATION regime (#744 depurination) and the ELECTROCHEMICAL regime (#593 Nernst) interact differently in µg. | | WAICO + Multigen + Genara-A — Arabidopsis Root Growth Across g-Levels | NASA/ESA | developmental biology/gravitropism | Eigenmass predicts: Gravitropism depends on statolith sedimentation — which requires gravity (§188 Archimedes principle VANISHES in µg). Without sedimentation, the statolith signal chain (auxin redistribution → differential growth) breaks. But the plant ADAPTS — alternative Ca²⁺ signaling pathways (governed by §593 Nernst) activate. This is a regime switch within the constraint graph: mechanical sensing → electrochemical, mediated by ion channel genetics. | | Rodent Research — Bone Loss and Muscle Atrophy in Space | NASA | musculoskeletal/mechanobiology | Eigenmass predicts: §316 Euler-Bernoulli beam equation for bone stress TRANSFORMS — the bending moment M and shear V from body weight vanish. The stress σ = My/I → 0. Osteocytes sense fluid shear stress in canaliculi (governed by #181 Poiseuille law for interstitial fluid flow). Without loading, fluid flow stops → osteocyte apoptosis → bone resorption. The constraint graph predicts this is a PURELY MECHANICAL cascade — no genetic adaptation can override a zero-stress signal. | | JAXA Myo Lab — Muscle Atrophy via Ubiquitination Pathway | JAXA | protein degradation/signaling | Eigenmass predicts: §360 Norton-Bailey creep law for mechanical degradation maps to protein turnover: dε/dt ∝ σ^n. When mechanical stress σ → 0 in µg, the strain rate → 0 — but the basal degradation rate (proteasome activity) is CONSTANT. The balance shifts to net catabolism. This is a thermodynamic necessity: the cell budgets protein mass against mechanical demand, and when demand disappears, the mass budget is cut. #68 Second Law — no free protein. | | Artificial Retina Manufacturing in µg | NASA/LambdaVision | thin-film/nanofabrication | Eigenmass predicts: §523 Thornton Structure Zone Model for thin film growth applies. In µg, Zone 1 (porous/columnar) growth is suppressed. Dense, defect-free films form because #464 Fick's law for protein diffusion dominates deposition rate. The absence of buoyancy-driven convection makes the protein concentration at the deposition surface exactly the bulk concentration — producing perfectly uniform layers. |
