Scientists have long thought most nitrogen in Earth’s ecosystems comes from the air, but new research shows it also is released as rocks weather. This could boost plant growth and help sequester carbon – but not fast enough to avert climate change, as some pundits have claimed.
The earth’s own magnetic field offers a useful way to measure the age of rocks - information that can help unpack ancient events and aid our understanding of the present.
Lightning strikes are powerful – but we haven’t had solid estimates of their energy until now. Researchers turned to the hollow stone tubes they create by vaporizing sand for more precise calculations.
A new study of the 2011 Christchurch earthquake shows boulders from rockfalls fell much further than in earlier quakes that happened before humans arrived and changed the landscape.
On printed maps, piling on the detail risks obscuring the meaning. This new digital map is really more of a database from which users can create different versions that match their own interests.
The Karoo provides not only a historical record of biological change over a period of Earth’s history but also a means to test theories of evolutionary processes over long periods of time.
A new mineral – dubbed “putnisite” – has been discovered in Western Australia. Mineralogy researcher Dr Peter Elliott from…
