A New Method for Probabilistic Spatiotemporal Forecasts of Solar Soft X‐Ray “S‐Class” (>X10) Superflares

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Solar superflares of S‐class (>X10 in soft X‐rays) pose extreme space weather hazards, yet their prediction remains a fundamental challenge owing to their rapid and transient natures and the limitations of conventional event‐based forecasts. We introduce for the first time, a probabilistic spatiotemporal framework designed to identify extended

The Role of Basal Roughness and Assemblage Grain‐Size Distribution in Shaping Granular Rheology and Basal‐Force Signals

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract We present idealized 3‐D discrete element simulations exploring how varying boundary roughness and grain‐size distribution affect bulk granular‐rheology and basal‐force distributions. Boundary roughness has a direct control on the internal static friction coefficient.

Frequently Reported Blood Biomarkers in Sarcopenia Clinical Trials: A Systematic Review and Meta‐Analysis

Aging Cell, Volume 25, Issue 2, February 2026.
This systematic review and meta‐analysis identifies blood‐based biomarkers (BBMs) reported in sarcopenia trials, investigating the impact of sarcopenia interventions on BBMs concentrations. Significant heterogeneity was observed in sarcopenia outcomes. Interventions had a limited impact on BBMs, except for IGF‐1, which was significantly impacted by the

A 50‐year perspective on the use and potential of artiodactyl calcanei in bone adaptation studies

Biological Reviews, Volume 101, Issue 1, Page 437-485, February 2026.
ABSTRACT Sheep and deer calcanei are important models for studying cortical (compact) and trabecular (cancellous) bone adaptation because they are amenable to direct strain measurement (due to lack of surrounding muscles), experience relatively simple/unidirectional bending, exhibit osteon remodelling, and have the most pronounced regional variations ...

LCA‐based evaluation of greenhouse gas reduction potentials of carbon/carbon wheel brakes for medium‐haul aircraft

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract Air transport is expected to substantially grow in the next decades, presenting a significant challenge for the aviation industry to reconcile this growth with the need to mitigate climate change by reducing greenhouse gas (GHG) emissions. A viable strategy for diminishing aviation emissions involves reducing aircraft fuel consumption, which ...
