This week, see what makes loggerhead sea turtles “dance,” track a cosmic “ghost particle,” uncover an ancient basilica, and more.

Dancing turtles show how animals use magnetic field as a map Dancing turtles have proved for the first time that some animals use Earth's magnetic field to create a personal map of their favourite ...

A new study from researchers at the University of North Carolina at Chapel Hill provides the first empirical evidence that ...

the magnetic north pole’s position is determined by Earth’s magnetic field, which is in constant motion. Over the past few decades, magnetic north’s movement has been unprecedented — it ...

Instead, magnetic north is the changing location where the planet’s magnetic field lines converge. This field is generated by the churning of the planet’s outer core, a layer of molten iron ...

Swarm is a constellation of three satellites that study Earth's geomagnetic field. This magnetic field that extends from Earth's interior into space is thought to be produced largely by an ocean ...
