An Aeolian Depositional Sequence Shaped by Near‐Surface Water at the Base of the Layered Sulfate Unit, Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract The basal strata of the orbitally defined Layered Sulfate unit (LSu) in Gale crater, Mars, marks the end of a major mineralogical transition from clay‐to sulfate‐bearing stratigraphy. This has previously been attributed to a period of significant aridification of Gale's climate. Here, we present ground‐based observations by the Curiosity rover

Quantitative evaluation of the effects of artificial grass and stem covers on overland flow hydrodynamics

Geoderma
Vegetation coverage on hillslopes substantially alters the hydrological and hydraulic erosion processes of overland flow; however, the mechanisms by which grass-shrub community coverage influences overland flow hydrodynamics remain insufficiently ...

Influence of Intrinsic Hydroxyl Content on Subcritical Crack Growth and Mechanical Reliability of Silica Glass

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT The role of internal hydroxyl (OH) content on subcritical crack growth (SCG) in silica glass was investigated using static fatigue testing combined with fracture‐mechanics‐based crack length analysis and Weibull statistical evaluation. Fourier‐transform infrared spectroscopy confirmed distinct OH concentrations in the investigated silica ...

Are physiological oscillations physiological?

The Journal of Physiology, Volume 604, Issue 9, Page 3672-3693, 1 May 2026.
Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

Current flight test experience related to structural divergence of forward-swept wings [PDF]

Flight testing the X-29A forward-swept wing aircraft has required development of new flight test techniques to accomplish subcritical extrapolations to the actual structural divergence dynamic pressure of the aircraft.
