New Geochemical Testing Confirms Cause of End-Permian Mass Extinction Event That Wiped Out Most Life on Earth
Results demonstrate the power of nickel isotope analyses, which are relatively new, to solve long-standing problems in the geosciences. The most severe mass extinction event…
Geoscientists Find That Shallow Wastewater Injection in Oil and Gas Production Fields Drives Deep Earthquakes in Texas
In a newly published paper, Virginia Tech geoscientists have found that shallow wastewater injection – not deep wastewater injections – can drive widespread deep earthquake…
Solving a Martian Climate Puzzle: Icy Clouds Could Have Kept Early Mars Warm Enough for Rivers and Lakes

“Beast From the East” – Snow Chaos in Europe Caused by Melting Sea-Ice in the Arctic
The April snow falling on fruit blossoms in Europe these days may be directly connected to the loss of the sea ice in the Barents…
NASA Satellites Detect Signs of Unrest Years Before Volcanic Eruptions
New research methods may lead to earlier predictions of volcanic eruptions. Although there are telltale signs that a volcano is likely to erupt in the…
Meandering Rivers Naturally Create “Counter-Point Bars” No Matter Underlying Geology
It’s not uncommon for crescent-shaped swaths of sand to dot the shorelines of meandering rivers. These swaths usually appear along the inner side of a…
Solar Activity Reconstructed Over a Millennium – Sun’s Eleven-Year Cycle Traced Back to the Year 969
An international team of researchers led by ETH Zurich has reconstructed solar activity back to the year 969 using measurements of radioactive carbon in tree…

Could the Surface of the Martian Moon Phobos Reveal Secrets of Mars’ Past?
The Martian moon Phobos orbits through a stream of charged atoms and molecules that flow off the Red Planet’s atmosphere, new research shows. Many of…
There’s Lots of Water in the Most Explosive Volcano in the World
Shiveluch, an active volcano located on the Kamchatka Peninsula in northeastern Russia, has had more major eruptions than any other volcano in our current period…
Centuries Old Climate Records Reconstructed From a 600-Year-Old Marine Sponge
Temperature records show past volcanic activity, current climate warming trends. Scientists used a 600-year-old marine sponge to reconstruct a record of ocean temperature in the…
“Different Than Previously Thought” – Geochemists Measure Composition of Earth’s Mantle
Researchers suspect greater dynamics than previously assumed between the Earth’s surface and its mantle. What is the chemical composition of the Earth’s interior? Because it…
Drying, Less Predictable Climate May Have Spurred Human Evolution
A progressively drying climate punctuated by variable wetter episodes may have precipitated the transition from our hominin ancestors to anatomically modern humans, according to research…
Galileo Reveals Million Fold Increase in the Power of Chorus Waves Near Jupiter’s Moon Ganymede
Listening to electro-magnetic waves around the Earth, converted to sound, is almost like listening to singing and chirping birds at dawn with a crackling campfire…
Geomorphic Evidence for Water on Ancient Mars
The climate of early Mars is a subject of debate. While it has been thought that Mars had a warm and wet climate, like Earth,…
