Geology & Volcanology
- Theory 02 · Arcs Form Where Slabs Tear
Volcanic arcs are located by tears in the subducting slab rather than by the depth of the slab beneath: magma rises through the tear, so arc gaps and anomalous volcanism mark slab segmentation rather than changes in the mantle wedge. - Theory 01 · The Roof Sets the Size
The size of a supereruption is set by the strength and geometry of the chamber roof rather than by the volume of recharge: magma arrives continuously, but the eruption begins when the roof fails, so size is a property of the lid.
Energy & Power Systems
- Theory 20 · Grid Batteries Age by the Clock
Degradation of stationary lithium-iron-phosphate batteries is dominated by calendar time at temperature rather than by cycle count, so a battery that sits idle at high temperature ages as fast as one that cycles, and warranty metrics based on cycles misprice storage. - Theory 19 · Where Inertia Sits Matters
Grid frequency stability is set by the spatial distribution of inertia rather than by its total, so two grids with identical inertia can have different stability, and adding inertia in the wrong place can worsen the response.
Sleep & Chronobiology
- Theory 22 · Chronotype Is Set in the First Year
Adult chronotype is set by the light environment during the first postnatal year rather than by genetic predisposition alone, so season of birth should predict chronotype and circadian disorder risk decades later. - Theory 21 · Sleep Is Local Before It Is Global
Sleep pressure accumulates in the cortical regions that were used, so sleep is spatially inhomogeneous and the transition to sleep begins locally: performance lapses should be predicted by local slow-wave activity rather than by time awake.
Archaeology & Human Origins
- Theory 16 · The Coast Came First
The first peopling of the Americas was coastal rather than interior, so the earliest archaeological signature is underwater, and the absence of early interior sites is a prediction rather than a problem.
Meteorology & Severe Storms
- Theory 04 · Hail Size Is Residence Time
Maximum hail size is set by how long a stone remains in the growth region rather than by peak updraft speed, so hail size is controlled by storm depth and trajectory geometry rather than by the strongest vertical velocity. - Theory 03 · Tornadoes Need a Ratio, Not a Fuel Supply
Tornadogenesis is controlled by the ratio of low-level shear to cold-pool strength rather than by CAPE, so a storm's tornado potential is set by a balance and not by the energy available to it.
Nutrition & Metabolism
- Theory 08 · It's the Rate, Not the Duration
The benefits of fasting are set by how fast ketones rise, not by how long fasting lasts, so interventions that accelerate the ketogenic switch should produce the same effects in less time, and slow switchers should show little benefit from long fasts. - Theory 07 · Appetite Is a Protein Thermostat
Energy intake is regulated to a protein target rather than to a calorie target, so diluting dietary protein drives overconsumption, and the obesity transition is partly a consequence of cheap, protein-dilute food.
Developmental Biology
- Theory 12 · Left-Right Is a Timing Window
Left-right asymmetry is set by a brief developmental window during which nodal flow is competent to break symmetry, so the direction is fixed but the probability of reversal depends on flow rate and timing rather than on the direction of flow alone. - Theory 11 · Organs Stop at a Stress Set Point
Organ size is set by a mechanical set point rather than by a cell-count programme: growth continues until the tissue's mechanical stress reaches a target, so perturbing tension changes final size without changing the genetic programme.
Hydrology & Water Resources
- Theory 06 · Recharge Happens in Extremes
Groundwater recharge is dominated by a small number of extreme rainfall events rather than by seasonal totals, so aquifer replenishment should be predicted from storm statistics and a threshold, not from annual rainfall. - Theory 05 · Banks Set the Width
River channel width is set by bank strength rather than by discharge, so two rivers carrying the same flow can have very different widths, and width responds to vegetation and clay content rather than to flow regime alone.
Plant Science
- Theory 14 · Exudates Are a Nitrogen Sensor
Root exudation is a nitrogen-sensing behaviour rather than a passive carbon leak: plants release specific compounds when nitrogen is scarce to recruit nitrifying partners, so exudate composition should predict nitrogen availability better than soil concentration does. - Theory 13 · Leaves Remember the Air They Grew In
Stomatal density carries a memory of the atmospheric carbon dioxide experienced during leaf development rather than tracking current concentration, so plants acclimate with a lag of one leaf generation and forests respond to CO2 change more slowly than models assume.
Pharmacology & Drug Action
- Theory 09 · Tolerance Is a Prediction
Drug tolerance is a learned prediction of the drug's effect rather than receptor desensitisation: it is context-specific, so it should be abolished by changing the cues that predict administration, and overdose risk should track cue novelty rather than dose. - Theory 10 · Toxicity Is a pH Problem
Off-target toxicity of weakly basic drugs is set by the pH of the tissues that sequester them rather than by receptor affinity, so toxicity should be predicted from tissue pH and lysosomal trapping rather than from selectivity assays.
Index narrowed to the focused science collection. Biological and ecological population dynamics, genetics, physiology and engineering are retained. Source numbering remains historical; no remaining hypothesis has been promoted to a finding.
