Birds can use two kinds of information from the geomagnetic field for navigation: the
direction of the field lines as a compass and probably magnetic intensity as a component of …

Biological systems are dynamical, constantly exchanging energy and matter with the
environment in order to maintain the non-equilibrium state synonymous with living …

The biophysical and molecular mechanisms that enable animals to detect magnetic fields
are unknown. It has been proposed that birds have a light-dependent magnetic compass …

The geomagnetic field provides directional information for birds. The avian magnetic
compass is an inclination compass that uses not the polarity of the magnetic field but the …

Quantum-enhanced sensing and metrology pave the way for promising routes to fulfil the
present day fundamental and technological demands for integrated chips which surpass the …

In the mid-1990s, it was proposed that quantum effects in proteins known as microtubules
play a role in the nature of consciousness. The theory was largely dismissed due to the fact …

Highlights•Bird colour vision depends on opsins, retinal mosaic, ocular media and oil
droplets.•Birds use spectral cues for phototaxis, magnetoreception and circadian …

Abstract Background The Japanese quail (Coturnix japonica) is a popular domestic poultry
species and an increasingly significant model species in avian developmental, behavioural …

Cryptochromes are a class of flavoproteins proposed as candidates to explain
magnetoreception of animals, plants and bacteria. The main hypothesis is that a biradical is …

The cryptochrome/photolyase (CRY/PL) family represents an ancient group of proteins
fulfilling two fundamental functions. While photolyases repair UV-induced DNA damages …
