New seismic imaging study of the Puysegur Trench aims to solve one of the last major questions in plate tectonics.

Scientists discovered magmatic remnants of a volcanic arc by dating granitic rocks of the middle crust excavated by, and hidden within, the Chicxulub impact crater.

A community effort finds that carbonate standards eliminate the interlaboratory differences plaguing carbonate clumped-isotope thermometry studies.

Cassini’s final flybys of Saturn’s largest moon may have captured a temperature drop due to rainfall, one of the first observations of weather changes on Titan.

By compressing iron oxide to pressures expected inside a large and rocky exoplanet, scientists discovered that such mantles could layer, mix, and flow in ways very different from those inside our planet.

Changing the way emissions are tallied may help litigators focus on the worst climate offenders and shape mitigation.


A new study confirms that an important wind system is shifting due to climate change.

A new analysis of seismic data from the Middle America Trench suggests that previous calculations have vastly overestimated the total amount of water transported to the mantle worldwide.

A new analysis suggests that a widely accepted approximation of ancient magnetic field strength may be less accurate for the past 5 million years than previously thought.
