We present experimental results of dust mobilization on a solid surface under an electron beam with grazing incidence. When the electron beam energy has a secondary electron yield greater than 1, dust particles move in the opposite direction of the electron beam. This is caused by asymmetric chargin…

A new data visualization illustrates how an experimental NASA technology can provide extra lead time to communities in the path of a tsunami. Called GUARDIAN (GNSS Upper Atmospheric Real-time Disaster Information and Alert Network), the software detects slight distortions in satellite navigation signals to spot hazards on the move.

The field of solar geoengineering revolves around the idea of cooling the globe via the injection of aerosols to reflect sunlight or to thin clouds. One such strategy, stratospheric aerosol injection (SAI), aims to mimic the effects of a volcanic eruption. Volcanoes spew sulfur dioxide into the stratosphere, which then reflects light back into space, cooling Earth for potentially a year or longer, as documented in previous eruptions.

This winter was one of the warmest on record across the West. As a result, many snowy, alpine areas have seen bouts of winter rainfall where there would ordinarily only be snow. These unusual weather patterns have contributed to an abysmal ski season, but they can also set the stage for dangerous avalanches.

Green clay tennis courts are able to absorb massive amounts of carbon dioxide via enhanced rock weathering, according to a new study in Applied Geochemistry. Enhanced rock weathering—the process of using silicate rocks like basalt to remove carbon dioxide from the atmosphere through the rocks' chemical reaction with rainfall—has emerged in recent years as a promising method of reducing carbon emissions. Green clay tennis courts in the US are made of metabasalt, a type of basalt with similar properties allowing for carbon sequestration.

Arctic rivers wind through remote tundra and boreal forests, freezing solid in winter and surging each spring with snowmelt, eventually emptying into the ocean. Runoff—water that does not soak into the ground but instead flows over the land surface—further increases the volume of freshwater entering the sea.

The soil beneath our feet is a huge carbon bank storing up to approximately three times more carbon than the entire atmosphere. That makes it a significant player in the future of our climate. If even a small fraction of the carbon escapes into the air as carbon dioxide, it could accelerate planetary heating. But what determines whether the carbon stays in the ground or escapes? According to new research published in the journal Nature Climate Change, water is the deciding factor. The wetter the soil, the more carbon stays in the ground.

In Science of The Total Environment, researchers demonstrate the broad distribution of particulate thiols in the western North Pacific and show that their main source is marine phytoplankton. The analysis indicates that differences in thiol concentrations between ocean areas are significantly influenced by water mass properties, phytoplankton composition, and environmental stress.

Alaska's glaciers respond to climate change by melting for three additional weeks with every 1 degree Celsius increase in the average summer temperature, data from satellite-mounted radars show.

For half the world's population, the water in their drinking glasses comes from below them. Groundwater also supplies 40% of global irrigation projects. Alarmingly, more than a third of the planet's aquifers, or groundwater basins, are dropping. Declining water tables leave entire regions vulnerable to drought, land subsidence or seawater intrusion while damaging ecosystems and reducing water access. Properly securing this resource is a matter of social, humanitarian and environmental security.

Every time we do a load of laundry, tiny fibers of polyester escape from our clothes and slip down the drain. These microfibers, so small they can be invisible to the naked eye, are among the most common forms of microplastic in the ocean. Yet, new research published in Journal of Geophysical Research: Oceans shows that most of them may not make it that far.

A potentially huge underground reservoir of freshwater beneath the Great Salt Lake is coming into sharper focus with a new study that used airborne electromagnetic (AEM) surveys to X-ray geologic structures under Farmington Bay and Antelope Island off the lake's southeastern shore.

New research reveals that "foundation models" trained on vast, general time-series data may be able to forecast river flows accurately, even in regions with little or no local hydrological records. The approach could improve flood warnings, drought planning and water-resource management in parts of the world where monitoring data is limited.

SummaryThe Southern Apennines—Northern Calabrian boundary is a region marked by lithological heterogeneity, complex geodynamics and tectonics, and prone to significant seismic hazard. This sector is part of a complex geodynamic system, where Africa-Eurasia convergence, Ionian subduction, and slab retreat coexist. Its structure and seismic activity derive from extensive lithospheric heterogeneity and fluid-related processes, both of which are poorly constrained. Here, we present a novel application of seismic attenuation and scattering tomography of the area at a regional scale. We estimated seismic wave attenuation and scattering for the Southern Apennines—Northern Calabria region using a dataset of 1581 waveforms related to 95 M ≥ 3.0 earthquakes that occurred between 2004 and 2024 and were recorded at 32 stations. We constrained the heterogeneous properties and fluid saturation of the Southern Apennines—Northern Calabrian region by mapping P-wave Peak Delays and inverting coda-normalized energies for total attenuation (1/Q). Results consistently reveal different seismic energy dissipation mechanisms between the two domains, reflecting their different characteristics in terms of Peak Delay and attenuation patterns. The Southern Apennines exhibit high Peak Delay values at all depths and almost no remarkable total attenuation anomalies, consistent with weakly consolidated, fractured sedimentary sequences and limited fluid content. Nevertheless, at a depth of 5.4 km, a relatively high attenuation pattern is detectable, likely linked to the presence of less cohesive and potentially fluid-saturated units. Conversely, Northern Calabria shows low Peak Delay and high attenuation in the investigated depth range, reflecting wave propagation through coherent crystalline rocks with significant fluid circulation, likely favored by overpressurized materials or active migration pathways. The spatial correlation between high attenuation, low seismic velocities, and thermal anomalies shows that fluids modulate seismic wave behavior, providing new constraints on the crustal structure and seismotectonic segmentation of the region. The joint interpretation of our results with other geophysical models and responses highlights the complex interplay between lithology, tectonics, and fluid dynamics across this critical segment of the central Mediterranean.
