Interactive explorationCharge a tiny membrane, disconnect its supply, and choose where the stored driving force goes. Discover how cells couple fuel chemistry to ATP—and why a bypass changes the result.
Interactive explorationBuild a virtual light filter, uncover a missing patch, explore real skin microscopy and inspect a DNA structure. Discover why visible light and warmth cannot tell the whole story.
Interactive explorationOpen real MRI-derived vocal-tract models, swap a vowel while holding the source steady, listen to measured-model sounds, and investigate what growth can change.
Interactive explorationExplore real picture cards, try remembering with and without clues, and compare recognition with context. Keep a private record, inspect published learning results and plan a review.
Interactive explorationOpen a connected follicle, follow its normal oil route, and compare structures hidden beneath the surface. Read real human microscopy and discover why acne is more than a story about dirt.
Interactive explorationOpen a protein-vaccine example, build a response with traceable cell lineages, and compare later encounters. Then follow the separate route from vaccine mRNA to a protein.
Interactive explorationExplore how the immune system responds to an infection. Follow immune cells from skin to lymph node, inspect an antibody structure, and discover what immune memory leaves ready.
Interactive explorationInspect real urinary anatomy, follow a glucose marker out of blood and back again, and discover three different crossings with a ledger that never loses a marker.
Interactive explorationTurn a real anatomical model in your hands. Reveal its chambers, meet the four valves, then follow the blood moving through both sides of the heart.
Interactive explorationMove through a breath, connect space to airflow, then cross the tiny boundary where oxygen enters the blood.
Move a load closer to an elbow on a transparent teaching arm. See the force change, then explore how muscles can work without visible movement.
Interactive explorationFollow a meal through the gut, then zoom into its lining. Choose starch, protein or long-chain fat and discover why their next routes differ.
