Microscopic dissection of chirality-induced spin selectivity in cryptochrome

Chirality-induced spin selectivity (CISS) has been proposed as a mechanism that enhances magnetic field sensitivity of radical pairs in magnetosensitive proteins, such as cryptochrome, through the recruitment of net spin polarization during radical pair formation and recombinatio...

Signals too small to sense: physical and information-theoretic limits to induction-based magnetoreception in birds

A recent study (Nordmann et al. 2025 Science 391, 1155-1160 (doi:10.1126/science.aea6425)) proposes that magnetoreception in pigeons may arise from electromagnetic induction within the semicircular canals of the inner ear. In this framework, motion through the geomagnetic field i...
