For generations, scientists have probed the structure and composition of the planet using seismic wave studies. This consists of measuring shock waves caused by earthquakes as they penetrate and pass ...

Current understanding is that the chemical composition of the Earth's mantle is relatively homogeneous. But experiments now show that this view is too simplistic. Their results solve a key problem ...

The global "hum" of the Earth is now helping scientists probe the planet's deep interior, a group of researchers say. Since this hum — called seismic noise, which is generated by sources such as storm ...
