The meninges wrap the brain in three distinct layers: the tough outer dura mater, the web-like arachnoid mater, and the delicate pia mater clinging to the brain's surface.
The blood-brain barrier isolates the brain from toxins and from the wild fluctuations in hormones, ions, and neurotransmitters that course through the rest of the body.
5 kilograms, a small fraction of total body mass. Despite that modest size, the brain consumes a disproportionate share of the body's energy budget and is housed inside a heavily fortified architecture.
Despite the enormous diversity of life, the cell category bifurcates into exactly two types: prokaryotic and eukaryotic.
Cells sit between organelles (their internal components) and whole organisms (their collective assemblies), forming one node in a nested hierarchy of biological organization.
Total protein grams matter less than the leucine threshold. 6–3 grams of leucine per meal saturates the muscle protein synthesis (MPS) response — going well beyond that in one sitting delivers diminishing returns.
This Obsidian entry for a university bioinformatics class is a skeleton with no actual content — just ontology tags, a Dataview query, and empty Notes/Flashcards sections.
Nathan does not treat the AI's first draft as the deliverable.
Ecologists use the symbol K to denote the maximum number of organisms a region can sustain without environmental degradation.
Jung's concept of the Shadow holds that every person carries a repository of traits they refuse to own and actively repress.
Nathan had 58 doctrine cards in one vault and 3,860 academic notes in another, with zero overlap between them. The two systems couldn't see each other's contents, so neither had the full picture of his thinking.
Rather than maintaining two parallel card directories, point one vault at another's folder via symlink. md files) without copying a single file.
The three most frequently used body planes in anatomy are the sagittal plane (dividing left from right), the frontal/coronal plane (dividing anterior from posterior), and the transverse plane (dividing superior from inferior).
Health professionals and anatomists use three cardinal planes—sagittal, coronal (frontal), and transverse—as imaginary flat surfaces to describe how the body moves during exercise or any physical activity.
Carbohydrates are classified into four structural tiers based on the number of sugar units they contain: monosaccharides (single units), disaccharides (two units), oligosaccharides (a few units), and polysaccharides (many units).
Carbohydrate consumption during exercise becomes meaningfully relevant once a workout crosses the 90-minute mark.
McEvoy's dry-land work combines calisthenics, gymnastics, rock climbing, and traditional gym training aimed at improving strength-to-weight ratio.
McEvoy avoids extensive easy swimming because he believes training at speeds away from race pace actually detracts from optimal sprint mechanics.
Traditional sprint swimmers log 30-60km per week in the pool. Cam McEvoy, who broke the 50m freestyle world record, trains just 2-3km per week — roughly 5-10% of the conventional volume.
Dax Hill argues that traditional high-volume swimming persists through generational inertia, not evidence.
0s or slower. The 15-35m segment is the key differentiator between elite and great — superior first-15m diving cannot compensate for a slow mid-race segment.
06s, Paris 2024) came after he dropped training volume from 30,000m/week to 8,000m/week — a 73% reduction. 9% of swimmers are burned out by traditional high-yardage methods that develop the wrong energy system.
Anyone designing a caloric restriction protocol must account for the thyroid-mediated drop in basal metabolic rate. Aggressive cuts don't just reduce intake — they signal the body to spend less, eroding the deficit.
During caloric restriction, the body actively suppresses thyroid hormone production as an adaptive strategy to lower basal metabolic rate.
Industrialized populations get just 12-17% of calories from protein, while hunter-gatherer tribes consume 19-35% depending on location. Modern diets have measurably reduced protein-derived calories compared to ancestral baselines.
CLRs don't just trigger phagocytosis and ROS production — they shape the downstream adaptive immune response by influencing which cytokines are released when a pathogen is first encountered.
The defining feature of C-type lectin domains is that they require calcium to bind carbohydrates — the ion acts as a cofactor that shapes the binding pocket into its functional form.
C-Type Lectin Receptors function as 'carbohydrate readers' on the surface of macrophages and dendritic cells, identifying pathogens by the distinctive sugar patterns on their surfaces.
University degrees certify competence in skills that are well-understood, teachable, and widely held — which is precisely why they pay commodity wages. Education is an efficient system for producing replaceable labor.
Most people frame replaceability as a compensation problem. It's actually a freedom problem.
