Automated detection and temporal monitoring of crevasses using remote sensing and their implications for glacier dynamics

Annals of Glaciology, 2016
Detailed studies on temporal changes of crevasses and their linkage with glacier dynamics are scarce in the Himalayan context. Observations of temporally changing surficial crevasse patterns and their orientations are suggestive of the processes that ...

TNAP and PHOSPHO1 Function Synergistically to Afford Critical Control Over the Mineralization of the Postnatal Murine Skeleton

Advanced Science, EarlyView.
Biomineralization underpins skeletal development, yet its molecular control remains incompletely understood. Using a novel murine knockout model, this study reveals the essential and complementary roles of PHOSPHO1 and TNAP in postnatal skeletal development.

Multisensor Glacier Surface Classification Using Confidence-Aware Explainable Inverse-Mapping Neural Network

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Mapping snow cover at the end of the ablation season allows us to extract the snow line altitude (SLA). The SLA is an important proxy for the equilibrium line altitude of a glacier and an indicator of glacier health.

TP53 Loss Elevates NF‐κB‐IFN‐β‐MHC‐Ia Signaling to Promote NK Cell Resistance in Osteosarcoma

Advanced Science, EarlyView.
TP53 loss in a transforming or osteosarcoma cell promotes cytosolic DNA accumulation, activating NF‐κB‐dependent IFN‐β production. Autocrine IFN‐β signaling increases cell‐surface HLA‐Ia expression, strengthens inhibitory KIR signaling in natural killer cells, and thereby enables the affected cell to evade NK cell‐mediated cytotoxicity.

Characterization of the near-surface air temperature dynamics over glaciers using thermal infrared measurements

Frontiers in Earth Science
Alpine glaciers are undergoing rapid mass loss, primarily driven by rising summer air temperatures. However, the glacier microclimate, especially the role of atmospheric dynamics near the surface and turbulent fluxes, is not adequately understood.

A New Ordered Transformation‐Induced Plasticity Enables Exceptional Strength and Ductility in a B2 Medium‐Entropy Alloy

Advanced Science, EarlyView.
A novel B2‐ordered Ti‐Zr‐V‐Al medium‐entropy intermetallic is developed through controlled metastability engineering, which activates an ordered TRIP effect via a new B2→D019‐α2 transformation with a distinctive {0001}α2//{110}B2, <11‐20>α2//<100>B2 orientation relationship. This alloy achieves an elongation of ∼7%, a strength of ∼1.1 GPa, and superior

Systems thinking to adapt tourism to climate change: Application to summer glacier skiing in Switzerland

Annals of Tourism Research Empirical Insights
Climate change affects mountain tourism and summer glacier skiing, a highly vulnerable activity. This paper explores the complex dynamics affecting summer glacier skiing in Swiss Alpine destinations. The methodology involved conducting 26 semi-structured

Magneto‐Sono‐Enhanced Nanozyme Catalysis Drives ROS‐Mediated Pathogen Killing and Mitophagy‐Linked Inflammation Control in Bacterial Pneumonia

Advanced Science, EarlyView.
Nebulized BN@NF nanozymes integrate boron nanosheets with Nd‐doped iron phosphide to form a sono‐magneto‐responsive Z‐scheme heterostructure. Under ultrasound and magnetic activation, BN@NF amplifies ROS generation, eradicates bacteria, disrupts biofilms, and reshapes pulmonary inflammation through NF‐κB suppression, mitophagy promotion, and M1‐to‐M2 ...

Geomorphology of the Évettes alpine glacial landsystem: documenting the legacy of the Little Ice Age in the Western Alps, France

Journal of Maps
The end of the Little Ice Age (LIA) in the nineteenth century triggered glacial retreat across the Northern Hemisphere, leaving behind sediment-landform assemblages that preserve records of glacier behavior.
