Uranium isotopes reveal age and origin of volcanic rocks
From the beginning of time, uranium has been part of the Earth and, thanks to its long-lived radioactivity, it has proven ideal to date geological processes and deduce Earth's evolution. Natural uranium consists ...
On a tropical island, fossils reveal the past—and possible future—of polar ice

Why is Greenland covered in ice?
The ice on Greenland could only form due to processes in the deep Earth interior. Large-scale glaciations in the Arctic only began about 2.7 million years ago; before that, the northern hemisphere was largely ...
Smothered oceans: Extreme oxygen loss in oceans accompanied past global climate change
Seafloor sediment cores reveal abrupt, extensive loss of oxygen in the ocean when ice sheets melted roughly 10,000-17,000 years ago,according to a study from the University of California, Davis. Thefindings ...
Fracking confirmed as cause of rare 'felt' earthquake in Ohio
A new study links the March 2014 earthquakes in Poland Township, Ohio to hydraulic fracturing that activated a previously unknown fault. The induced seismic sequence included a rare felt earthquake of magnitude ...
