On our cover, chief science correspondent Raj Mukhopadyhay
looks at fresh developments in the loosely defined field of quantum biology,
including attempts to design relevant experiments and develop models that can
demonstrate quantum effects in biological processes. She hears from researchers
who have observed quantum effects – in enzyme catalysis, photosynthesis, and
the sensing of magnetic fields by migratory birds – but remain careful about
embracing quantum biology as a fully-fledged niche.
