If scientists could give living cells magnetic properties, they could perhaps manipulate cellular activities with external magnetic fields. But previous attempts to magnetize cells by producing iron-containing proteins inside them have resulted in only weak magnetic forces. Now, researchers have engineered genetically encoded protein crystals that can generate magnetic forces many times stronger than those already reported.
