Spin mixtures of degenerate fermions are pivotal in quantum many-body physics, yet achieving tuneable interactions without compromising stability remains challenging. Here, the authors demonstrate a universal s-wave resonance in fermionic dipolar spin mixtures, enabling stable, strongly interacting systems and advancing the potential for exotic quantum phases through precise microwave-field control.
