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

Loggerhead sea turtles do an excited "turtle dance" when anticipating food. It's adorable, of course, but it has also allowed scientists to understand better how the turtles navigate. Scientists have theorized that sea turtles memorize coordinates to navigate using a magnetic "map.

Loggerhead turtles can recognize the magnetic signatures that they associate with getting a nice meal – and do an adorable little dance when they do! That’s according to new research that suggests that these turtles use Earth’s magnetic field as a map and a compass in two different ways.
