Water and sanitation to reduce child mortality : the impact and cost of water and sanitation infrastructure [PDF]

open access: yes
Using household survey data, this paper estimates the mortality impact of improved water and sanitation access in order to evaluate the potential contribution of water and sanitation investment toward achieving the child mortality targets defined in ...

The Dynamics and Surface Signal of Slab Break‐Off in Continental Settings: Insights From 3D Numerical Modeling

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract The fate of an oceanic plate that has been subducted over an extended period of time involves slab break‐off, which can occur either simultaneously across the entire slab or locally, creating a tear that propagates sub‐horizontally. These processes are thought to explain various geological observations, such as the evolution of foreland basins,

Sensitivity of Stratocumulus–Cumulus Transitions in a Cloudy Energy Balance Model

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 5, May 2026.
Abstract Stratocumulus (Sc) clouds have high impact on the climate system because of their strong cooling effect (albedo). In the subtropical oceans they naturally break up into cumulus (Cu) as environmental conditions change, a phenomenon called Stratocumulus–Cumulus Transition (SCT).

Morphology and osteo‐histology of the weigeltisaurid wing: Implications for aerial locomotion in the world's first gliding reptiles

open access: yesJournal of Anatomy, Volume 248, Issue 5, Page 843-872, May 2026.
This study investigates the morphology and osteo‐histology of the wing skeleton of the world's first gliding reptiles, showing how it differs from those of extant gliding lizards, yet is also convergently similar. These findings pave the way for future biomechanical studies on the gliding locomotion of these emblematic fossil animals. Abstract The Late

Prefabricated foldable lunar base modular systems for habitats, offices, and laboratories [PDF]

open access: yes
The first habitat and work station on the lunar surface undoubtedly has to be prefabricated, self-erecting, and self-contained. The building structure should be folded and compacted to the minimum size and made of materials of minimum weight.

Hydraulic Control of the Foreshocks and Mainshock of the 2017 Valparaíso, Chile, Earthquake

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Slow‐slip events (SSE) are a key mode of aseismic deformation and can enhance fault permeability through fracturing, enabling fluid migration from the overpressured oceanic crust to the plate interface. Whether the resulting poroelastic stress changes promote seismicity and larger megathrust events, however, remains unclear.

Do Migrating Semidiurnal Tidal Winds From the Lower Atmosphere Control Thermospheric Winds?

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Lower atmospheric tides are important for driving the thermospheric and ionospheric structure. The effects of different lower atmospheric migrating semidiurnal tidal fields of neutral density, temperature, and winds on the thermospheric winds are investigated by using the global ionosphere‐thermosphere model with forcing of the tides at the ...
