Molecular action may help keep birds on course

Researchers have found a molecular mechanism that may explain how migratory birds use Earth’s magnetic field to orient themselves during seasonal journeys. They identified a molecule that reacts to very weak magnetic fields, proving the plausibility of the method of avian navigation. Devens Gust, chemistry professor, says the molecules "seem to have the right structural and chemical features to allow them to show this effect." Article source: Washington Post
