Summary: Supraglacial debris cover plays a significant role in shaping the dynamics of the Companion Glacier in the Central Himalaya. Field and remote sensing observations reveal that the glacier's geometry and area have remained relatively stable over the study period (2000-2020) due to the presence of thick debris and protected margins. The glacier also exhibits a less negative mass balance and an increase in average velocity compared to other glaciers in the region.

Summary: Research on surface processes of debris-covered glaciers is crucial for understanding the climate-glacier relationship, hydrological cycle, and natural hazards in High Mountain Asia. Numerical models play a significant role in studies due to the scarcity of long-term in situ data, but existing models have limitations in addressing coupled processes on debris-covered glaciers.

Summary: This study presents a detailed analysis of glaciers in the Alaknanda Basin, Central Himalaya, using high-resolution datasets. The results show that the glacier area has decreased and the number of glaciers has increased in the basin. There has also been a significant increase in the supraglacial debris cover extent of the glaciers. Smaller glaciers with lower altitude snout and higher slope have experienced more significant area loss and higher retreat rate, while topographic parameters and changes in winter-time temperature have influenced the deglaciation and fragmentation in the basin.

Summary: The relationship between glacier mass balance (MB) and runoff in the Himalaya has been poorly studied due to limited data. This study used a simplified glacio-hydrological model to reconstruct the long-term MB and runoff on two glaciers in different regimes of the Himalaya. The results show that the glaciers have experienced limited mass wastage and the catchment-wide runoff is correlated with the glacier mass balance.

Summary: The study revealed that glaciers in the Hindu-Kush Himalaya region have a large amount of debris cover in the ablation zone, which significantly slows down the ablation rate due to the increased thickness of supraglacial debris. Field measurements showed that approximately 15% of Chandra Basin is covered by supraglacial debris, with up to 90% debris cover in the ablation area of the studied glaciers.

Summary: This study develops two Normalized Difference Supraglacial Debris Indices for mapping debris-covered ice based on thermal and near Infrared Landsat 8 bands. They were calibrated with field data and validated to have high accuracy. The indices were then applied to Landsat data for 2016 to produce a detailed glacier inventory of the Afghanistan Hindu Kush Himalaya that includes debris cover. Principal components analysis identified the main drivers of debris-covered ice extent, and it was found that as glaciers shrink, the proportion of debris cover will become higher, emphasizing the importance of reliable debris cover mapping.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
