Earth is surrounded by a magnetic field generated by electric currents from within the planet. Compasses take advantage of this field to identify north and serve as a navigational aid. But one social ...

Researchers isolate the protein thought to help migratory birds navigate, and astronomers pinpoint the stars that could view Earth as an exoplanet. How migratory birds sense magnetic fields is a long ...

Atomic physicists “are jacks of all trades,” according to Alex Sushkov. “You have to have the idea, design the experiment, build the experiment, run the experiment, fix everything, take data, analyze ...

Loggerhead sea turtles (Caretta caretta) can learn to associate food with the geomagnetic signatures of various oceanic regions, suggesting that they are able to find known foraging areas using an ...

We may finally know the secret to how migrating birds can sense Earth’s magnetic fields: a molecule in their eyes called cryptochrome 4 that is sensitive to magnetism, potentially giving the animals ...
