A wealth of evidence suggests that magnetic compass of migratory birds is light dependent, with the eye involved in the sensing of the compass direction. Experiments with oscillating magnetic fields show that these can disrupt the behaviour of migratory birds. Studies showed that the ratio between singlet and triplet products in cryptochrome protein can be modulated by the Earth’s magnetic field.

LIFE on the EDGE Jim Al-Khalili & Johnjoe McFadden, Surrey University (2014) Summary and review of the above book INTRODUCTION: This book is important in trying to bring a serious discussion of quantum biology to a lay audience. The continuing need to bring quantum biology into the mainstream is indicated by the sceptical tone of some of the book’s reviewers and the still sparse start-class article provided on Wikipedia. The main drive of the book is to indicate that quantum coherence Read more […]

European robin migration

Bird migration may be facilitated by an ability to see and navigate the Earth’s magnetic field. The process is suggested as being started by light entering a bird’s eye. Light would excite two electrons of a molecule in the bird’s eye in such a way that one electron was moved to another molecule. However, the two electrons would remain quantum entangled despite being separated. This means that a change in the spin or magnetic orientation of one electron would immediately alter the spin of its entangled partner.
