Visualizing and Hearing the Brittle–Plastic Transition
Simultaneous optical, mechanical, and acoustic measurements reveal that brittle microcracking and crystal-plastic twinning in calcite generate distinguishable acoustic signals.
Cows, Coal, and Chemistry: The Role of Photochemistry in Methane Budget
Recent increases in atmospheric methane are a result of changing natural and manmade sources, climate, and other less-understood factors linked to its role in the…
Calibrating the Clocks: Reconciling Groundwater Age from Two Isotopes
A new quantitative model corrects for tracer-based age biases from 39Ar and 14C isotopes leading to more accurate estimates of groundwater residence times.
Kyanite Exsolution Reveals Ultra-Deep Subduction of Continents
Laboratory experiments provide the first experimental evidence that continental rocks can be subducted to depths greater than 300 kilometers and return to the surface.
Coastal Coralline Algae Naturally Survive Persistent, Extreme Low pH
Time-series monitoring shows that a coastal coralline algae reef is naturally exposed to extreme low pH levels, suggesting potential adaptation of this biodiverse habitat to…
How Satellite Data Helped Avoid Hunger from Drought
Satellites detecting anomalies of the spectral reflectance of crops in Uganda successfully foretold imminent crop failure and automatically triggered timely governmental disaster relief.
ALMA’s New View of the Solar System
High-resolution radio observations link the chemistry of local moons and comets to the birth environments of distant exoplanets.
Detecting Remagnetization with Quantum Diamond Microscopy
Scientists reconstruct the magnetization timeline of serpentinized rocks from the Troodos ophiolite by investigating remanent magnetization-carrying structures with a Quantum Diamond Microscope.
Where the Tianshan Will Break Next: Strain, Slip, and Seismic Hazard
Geodetic strain and slip deficits reveal where the Tianshan is storing stress and which faults may generate the next major earthquakes in the region.
Are We Really Seeing More Foreshocks with Enhanced Catalogs?
Different definitions and selection methods can lead to large differences in estimated foreshock rates; however, robust statistical method shows that foreshock rates are similar between standard and enhanced catalog.
Rethinking How to Measure Roots
Researchers present a new method for determining depth-dependent patterns of the root-soil interactions that drive ecosystem functions in the critical zone.
Central China Water Towers Provide Stable Water Resources Under Change
A new reconstruction of river runoff from 1595 shows that Central China water towers deliver the most stable water supply from the high mountain ranges of the Pacific Rim.
Managing Carbon Stocks Requires an Integrated View of the Carbon Cycle
The carbon cycle community calls for an integrated carbon observing system leveraging near-surface partial-column data to better resolve finer spatial scales where key processes and decisions occur.
Successful Liquid Lake Conditions in a Cold Martian Paleoclimate
Simulations from a new lake model explain how liquid water could have been maintained over Mars in a cold climate, thus resolving a critical scientific gap in our understanding of Mars’ early history.
Frictional Properties of the Nankai Accretionary Prism
A database of frictional properties from IODP drilling materials explores the range of slip spectrum and the generation of slow to fast earthquakes in the Nankai subduction zone in light of mineralogy.
