Late Campanian Arabia-Eastern Anatolia Collision
New sediment-provenance data date the closure of the southern Neotethys and the Arabia–Eastern Anatolia collision to 74–71 million years ago, at least 25 million years…
The Definitive Guide to the TEX86 Paleothermometer
A new review article summarizes our knowledge of how microbial lipids archived in marine sediments record ancient ocean temperatures and outlines challenges and next steps…
A New Pathway for Energy Redistribution in Near-Earth Space
In situ evidence of bidirectional wave-particle energy transfer enabled by local magnetic-field gradient reveals an inhomogeneity-driven pathway for energy redistribution.
Rising CO2 Alters Upper Atmosphere Response to Stratosphere Sudden Warming
A whole-atmosphere model simulation shows that rising CO2 changes how the upper atmosphere and ionosphere respond to a sudden stratospheric warming (SSW), with implications for…
Enhancing Induced Seismicity: A New Window into Earthquake Physics
Controlled multi-day hydraulic stimulation experiments in the BedrettoLab aim to generate seismicity in order improve the understanding for rupture processes of natural and induced earthquakes.
The Role of Tidal Wetlands in the Global Nitrogen Cycle Under Global Change
A new study of tidal wetland data highlights their capacity to sequester nitrogen (blue nitrogen), a function that could be weakened or even reversed by wetland area loss.
Redesigning Farmland Through Community Collaboration in California
A community-led project in California shows how collaboration can reshape farmland to improve water resources, restore native plants, and create recreational space.
Southeast Tibet Grew in Pulses, Not All at Once
Mineral cooling ages reveal three pulses when uplift and erosion exposed deeper rocks, showing that Southeast Tibet grew outward, step by step, over roughly 80 million years.
Making Weather and Climate Information Reach the Communities that Need It
Many at-risk communities remain unreached by forecasts due to barriers in language, access, and trust in information systems. A new study looks at how to overcome these.
A Satellite-Based Global Carbon Flux Product is Sensitive to Droughts
A parsimonious ecosystem model constrained by data from NASA’s Soil Moisture Active and Passive mission generates a global daily carbon flux product that is highly sensitive to drought and pluvial events.
The Largest Ice Thickness Survey of Alaska’s Glaciers
A decade of NASA airborne radar surveys produces the most extensive inventory of glacier ice thickness for Alaska and northwestern Canada to date.
Reconnecting to the Lunar Trailblazer with Light
Learning from the attempted rescue of the Lunar Trailblazer: how ground-based optical observations and laboratory measurements can improve recovery of the attitude of a spacecraft lost in space.
Fluid-Driven Reactions Restore Fault Strength Between Earthquakes
In fault gouge, fluids drive chemical healing by cementing grains, a mechanism for seismic slip in rocks frictionally expected to creep. This cohesion matters for fault stability.
Seeing Earth’s Most Common Minerals from Space
A novel method marks an important step toward mapping quartz and feldspar globally.
How Dehydration-Driven Fluid Pressure Shapes Megathrust Slip Modes
By modeling dehydration-driven fluid pressure, a new study links deep fluids to where megathrust earthquakes end and slow slip begins.
