A Fluvio‐Lacustrine Environment Preserved in the Jezero Crater Inlet Channel, Neretva Vallis, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Martian fluvial valleys provide evidence for the surface flow of liquid water, making them a key target for rover‐based investigations of ancient habitability. The Mars 2020 Perseverance rover spent ∼85 sols exploring the Bright Angel formation, exposed across the floor of Neretva Vallis: the western inlet channel of Jezero crater.

Reinforcement Training of Face Recognition Systems Using Morphing and XAI Methods

IET Biometrics, Volume 2026, Issue 1, 2026.
This study introduces a reinforcement training framework for face recognition systems (FRSs) that leverages facial morphing techniques to generate counterfactual visual instances for model enhancement. Two complementary morphing strategies were employed: a geometric approach based on Delaunay–Voronoi triangulation (DVT‐Morph) and a generative approach ...

Congo Basin Carbon Cycle Responses to Global Change

Global Change Biology, Volume 32, Issue 1, January 2026.
Understanding the resilience of the Congo Basin carbon cycle in the face of current and future pressures requires a detailed understanding of its response to past and present drivers of change. Building on a pantropical framework of drivers and possible regional mechanisms for resilience, this review provides the first comprehensive assessment of Congo

Mapping the density of giant trees in the Amazon

New Phytologist, Volume 249, Issue 1, Page 152-168, January 2026.
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...

Safety Assessment of Critical Aircraft Systems Under Multisource Uncertainty Based on Evidence Network

International Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
As civil aircraft components become more autonomous in China, airworthiness certification is facing the problem of insufficient failure data, leading to challenges in terms of uncertainty. Traditional probabilistic models struggle to effectively integrate multisource uncertainties, limiting their application in data‐scarce scenarios.
