Scientists probe how distinct liquid organelles in cells are created

The interior of a human cell consists, in part, of a complex soup of millions of molecules. One way these biological compounds stay organized is through membrane-less organelles (MLOs) — wall-less liquid droplets made from proteins and RNA that clump together and stay separate from the rest of the cellular stew. […]
