Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Direct Detection of Hydrogen Reveals a New Macroscopic Crustal Water Reservoir on Early Mars

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The next great leap in Martian exploration is the return of samples to Earth. Maximizing their scientific value requires non‐destructive analytical techniques for early three‐dimensional characterization. Neutron computed tomography (CT), highly sensitive to hydrogen, complements conventional X‐ray CT and enables the detection of hydrous ...

8-inch nano-polycrystalline hBN for neutron radiography

PhotoniX
Boron-based scintillators have attracted significant attention due to their high thermal neutron capture cross-section. However, large-area pure boron-based scintillators remain unexplored.

Neutron Reflectometry and Compression of Graded Hydrogel Surfaces

Advanced Materials Interfaces, Volume 13, Issue 15, 4 August 2026.
Highly‐entangled and covalently‐crosslinked hydrogels with thin and thick surface gel layers are compressed in neutron reflectometry experiments. Surface gel layer thickness dictates the extent to which the polymer network at the surface of a hydrogel collapses, while crosslinking chemistry, and therefore elastic modulus, impacts the pressure at which ...

Wide Temperature Zero Thermal Expansion in Al Matrix Composites with High Thermal Conductivity

Advanced Science, Volume 13, Issue 45, 13 August 2026.
Strain engineering strategy is implemented on the negative thermal expansion (NTE) phase Zn1.6Mg0.4P2O7 within composites, where Al matrix‐induced compressive strain drives uniform polyhedral and unit cell evolution, thereby enabling broad and consistent thermal compensation efficacy and obtaining good thermal performance.

Combined Neutron‐ and Synchrotron‐Based Diffraction Computed Tomography Studies of 18650‐Type Lithium‐Ion Cells

Batteries &Supercaps, Volume 9, Issue 8, August 2026.
Combined neutron‐ and synchrotron‐based diffraction computed tomography reveals the spatial distribution of lithium in commercial 18650 lithium‐ion batteries. Non‐destructive multi‐scale imaging uncovers heterogeneities linked to cell geometry, state of charge and ageing.

Spatial variability of denudation rates and transient landscape adjustment in low‐deforming mountains (the Strengbach catchment, Vosges Mountains, France)

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Erosion across the landscape is described at first order by a limited number (nine) of homogenous geomorphological and lithological domains. Using a dense set of basin wide denudation rates, it is possible to retrieve the contribution of each litho‐morpho‐domains as a function of their respective surface.
