12 Features

🔬Microbe Atlas

17 species across Bacteria, Archaea, Eukarya, and Viruses. Tap for full details.

🧫Cell Structure

Cross-sections of all three domains — nucleoid, S-layer, mitochondria.

⚙️Cell Division

Binary fission, budding, sporulation. N(t) = N₀ · 2^(t/g).

🧪Petri Dish

Tap to inoculate. Tune temperature, pH, nutrient and watch colonies grow.

🧱Biofilm

Attachment → matrix → maturation → dispersal. Quorum sensing visualized.

🧭Chemotaxis

Run-and-tumble toward attractants, away from repellents. Tap to move the source.

🍶Fermentation

Lactic / yeast / koji metabolism. Live pH and CO₂ output.

🦠SIR Simulator

180 agents. Real-time epidemic curve and R₀.

🗾World Map

Metapopulation SIR over 7 Japanese regions. Try lockdown and vaccination.

🛡️Immune System

Macrophages chase and engulf pathogens.

💊Resistance Evolution

Antibiotic pressure → mutation → resistant strains spread.

🌳Tree of Life

From LUCA to Bacteria, Archaea, and Eukarya — pinch to zoom.

Highlights

Microscope-first

See before you compute. Agent-based simulations make biology intuitive.

Clean UI

Material Design 3. Light / dark themes. Japanese and English.

Learning reference

Formula sheet on every screen. SIR, logistic growth, selection — modern biology essentials.
