We undertook a 28-day voyage to explore a possible lost continent in a remote part of the Coral Sea, in an area off the coast of Queensland. Here's what we found.
Giant forces slowly move continents across a viscous layer of the Earth, like biscuits gliding over a warm toffee ocean. This stresses the continents, and twists and contorts the crust.
Fresh earthquakes and aftershocks hit parts of Papua New Guinea following February's deadly quake. It's Australia's slow push north that's part of PNG's seismic activity.

Fire has been viewed as the main protagonist in creating Africa's iconic savannas. However, new research shows that browsing animals created savannas millions of years before fire became important.
Fifty years on from a groundbreaking paper, geophysicists have progressed from believing continents never moved to thinking that every movement may leave a lasting memory on our planet.
