Modelers are using recent gains in computational power to consider the complex interactions of hundreds or thousands of macromolecules at once--a necessary first step toward whole cell simulation
Molecules in cells behave like people in crowded subway cars. Because they can barely budge or stretch out without bumping into a neighbor, they move more slowly, smush themselves into more compact...

A model of chromatin explores how it folds and unfolds
To fit an organism’s DNA into a single cell, it has to be tightly compacted, first wound around proteins to form chromatin fibers, then further coiled into chromosomes. Computer simulations by...
