Scientists have long thought that tectonic plates needed to dive beneath each other to create the chemical fingerprint we see ...

The study also provides a new approach to solving one of the biggest enduring scientific mysteries: when did plate tectonics begin?

But life emerged prior to that; we have fossils of microbes from 3.48 billion years ago. And scientists think that conditions on Earth may have been stable enough to support life from around 4.3 ...

In a new paper published in Nature today, colleagues and I reveal secrets of Earth's crust 4.5 billion years ago. In the process, we also provide a new way to approach one of the biggest enduring ...
