Although it has been known for almost half a century that migratory birds can detect the
direction of the Earth's magnetic field, the primary sensory mechanism behind this …

For centuries, humans have been fascinated by how migratory animals find their way over
thousands of kilometres. Here, I review the mechanisms used in animal orientation and …

Quantum mechanics provides the most accurate microscopic description of the world around
us, yet the interface between quantum mechanics and biology is only now being explored …

The three-volume work Perceiving in Depth is a sequel to Binocular Vision and Stereopsis
and to Seeing in Depth, both by Ian P. Howard and Brian J. Rogers. This work is much …

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 …

Migratory birds travel vast distances each year, finding their way by various means,
including a remarkable ability to perceive the Earth's magnetic field. Although it has been …

Migratory birds have a light-dependent magnetic compass, the mechanism of which is
thought to involve radical pairs formed photochemically in cryptochrome proteins in the …

Birds seem to use a light-dependent, radical-pair-based magnetic compass. In vertebrates,
cryptochromes are the only class of proteins that form radical pairs upon photo-excitation …

Birds are renowned for their exceptional vision and the way that this enables them to survive
and navigate the world in such a unique way. However, it is now recognised that avian …

Behavioral variation abounds in nature. This variation is important for adaptation and
speciation, but its molecular basis remains elusive. Here, we use a hybrid zone between two …
