Lithic Miniaturization Provides a Signature of an MIS4‐3 Southern Dispersal of Homo sapiens

Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 1, March 2026.
ABSTRACT Fossil and artefactual evidence shows Homo sapiens in Eurasia well before 75 ka. However, genetic evidence suggests all extant non‐African populations derive almost all of their ancestry from a dispersal that only diverged in the last 60–50 ka. In northern Eurasia, the Upper Paleolithic with its laminar blade knapping provides an archeological

Algal Blooms in Lakes Increase After Wildfire Smoke Events in the Contiguous United States

Global Change Biology Communications, Volume 1, Issue 1, March 2026.
Temporary pulses of surface chlorophyll‐a are identified following wildfire smoke events in lakes and reservoirs across the United States. ABSTRACT Area burned by wildfire has increased in the contiguous United States and in many places globally in recent years, impacting communities and ecosystems nearby and even far downwind of fires. We examined the

Summertime methane and carbon dioxide emission rates and associated variables from a national‐scale survey of 146 reservoirs in the United States

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Reservoirs are globally important sources of greenhouse gases, but the magnitude of their emissions is highly uncertain. Here, we present data for 146 reservoirs from two surveys of reservoir methane and carbon dioxide emissions, one at the regional scale in the midwestern United States and one at the national scale in the United States, plus ...

Aquatic reflectance derived from Sentinel‐2 Multispectral Imager data for inland waters in the conterminous United States

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Satellite‐based earth observation is a robust tool for tracking change in ecosystems. While terrestrially focused applications of remote sensing have empowered wide adoption for research and management, remote sensing of inland aquatic ecosystems remains comparably nascent.

Neue Methode zum Neutrinonachweis: Kohärente Streuung von Neutrinos an Atomkernen

Physik in unserer Zeit, Volume 57, Issue 2, Page 79-83, March 2026.
Neutrinos sind sehr schwer nachweisbare Elementarteilchen, die selbst in riesigen Experimenten kaum Spuren hinterlassen. Nun ist es erstmalig gelungen, diese winzigen Teilchen mit einer vergleichsweise kleinen Messapparatur an einem Kernreaktor über die sogenannte kohärente elastische Neutrino‐Kern‐Streuung zu beobachten. Zusammenfassung Neutrinos sind

Pseudo‐diffusivity characteristic curves for surface–rootzone soil hydrologic connectivity

Vadose Zone Journal, Volume 25, Issue 2, March/April 2026.
Abstract Accurate quantification of the rootzone soil moisture (θ) dynamics and hydrologic thresholds is important to advance sustainable agricultural water management and drought monitoring. Various low‐pass filters are popularly used to generate a first‐order approximation of θ, referred to here as θ̂$\hat{\theta }$, from temporally smoothed and ...

Streamflow in the United States: Characteristics, trends, regime shifts, and extremes

Scientific Data
Long-term streamflow observations contain essential information for understanding hydrological changes and managing water resources. A continental-scale dataset or analysis of temporal streamflow change is still lacking across hydrologic gauges in the ...

Modeling soil moisture from rainfall: An evaluation of the diagnostic soil moisture equation

Vadose Zone Journal, Volume 25, Issue 2, March/April 2026.
Abstract The diagnostic soil moisture equation (DSME), which estimates soil moisture from antecedent precipitation, can be used to gap‐fill and extend existing in situ records. We train and evaluate the DSME at 157 Soil Climate Analysis Network and 113 US Climate Reference Network (USCRN) stations across the contiguous United States.

Assessing Flash Drought Development and Propagation Across the Contiguous United States Using Remote Sensing

Earth's Future, Volume 14, Issue 3, March 2026.
Abstract Flash droughts are characterized by rapid onset and intensification, with severe impacts on agriculture and ecosystems. They often begin as meteorological droughts and, if conditions worsen, evolve into agricultural droughts. While precipitation deficit is often the primary driver, atmospheric and hydrological anomalies can exacerbate flash ...

Significant Influence of Lateral Carbon Fluxes on Regional U.S. Carbon Budgets

Global Biogeochemical Cycles, Volume 40, Issue 3, March 2026.
Abstract Observations of atmospheric carbon dioxide (CO2) are expected to play a critical role in monitoring, reporting, and verification designed to track progress toward the reduction goals of greenhouse gas emissions. In this study, we construct a comprehensive regional carbon budget for seven National Climate Assessment regions of the contiguous ...
