The biggest shark attack in history did not involve humans. A new study by earth scientists has turned up a massive die-off of sharks roughly 19 million years ago. It came at a period in history when there were more than 10 times more sharks patrolling the world’s oceans than there are today. Title: A … A shark mystery millions of years in the making
Seismic waves generated by earthquakes travel through Earth’s solid iron inner core faster in the direction of the rotation axis than along the equator. Scientists created a core growth model to explain this. To fit seismic data, the model predicts that asymmetric growth of the core leads to crystal movement that preferentially aligns iron-nickel crystals … Is Earth’s core lopsided? Strange goings-on in our planet’s interior
Twice a day, at dusk and just before dawn, a faint layer of sodium and other metals begins sinking down through the atmosphere, about 90 miles high above the city of Boulder, Colorado. The movement was captured by one of the world’s most sensitive ‘lidar’ instruments and the regularly appearing layers promise to help researchers … Atmospheric metal layers appear with surprising regularity
Although sun radiation was relatively low, the temperature on the young Earth was warm. An international team of geoscientists has found important clues that high levels of carbon dioxide in the atmosphere were responsible for these high temperatures. It only got cooler with the beginning of plate tectonics, as the CO2 was gradually captured and … Extreme CO2 greenhouse effect heated up the young Earth
The cause of Earth’s deepest earthquakes has been a mystery to science for more than a century, but a team of scientists may have now cracked the case. New research provides evidence that fluids play a key role in deep-focus earthquakes — which occur between 300 and 700 kilometers below the planet’s surface. Title: What … What causes the deep Earth’s most mysterious earthquakes?
With the expansion of oxygen-depleted waters in the oceans due to climate change, some species of foraminifera (forams, a type of protist or single-celled eukaryote) that thrive in those conditions could be big winners, biologically speaking.

shows that a relaxation in the thick aggregate of icebergs floating at the glacier-ocean boundary of the Jakobshavn Isbræ occurs up to an hour before calving events. This finding may help scientists better understand future sea-level rise scenarios and could also help them predict when major episodes of calving are about to occur. Title: Slushy … Slushy iceberg aggregates control calving timing on Greenland’s Jakobshavn Isbræ
There has long been controversy about whether the world’s highest region, Tibet, has grown taller during the recent geological past. New results indicate that the ‘Roof of the World’ appears to have risen by up to 600 meters and the answer was found in underwater lava. The knowledge sheds new light on Earth’s evolution. Title: … Geological riddle solved: Roof of the World has gotten higher
QUT researchers have used experimental x-ray techniques at the Australian Synchrotron to gain fundamental insights into how gypsum dehydrates under pressure and the processes that create earthquakes.
