2D lattice HP model folding. Drag residues to minimize energy. Simulated annealing auto-fold. Known optimal energies.

Detect and classify blood cells in microscope view. RBC, WBC, platelets. Pie chart distribution. Manual vs AI count.

Animate DNA→mRNA→Protein. Click bases to mutate — see silent, missense, and nonsense mutations. Codon table included.

Atoms interacting via Lennard-Jones potential. Adjust temperature for phase transitions: solid → liquid → gas. Click to add energy.

Natural selection in action. Creatures eat, reproduce with mutations, evolve traits. Add predators for selection pressure.
