The southeastern region of Tibet, which serves as the primary concentration area for marine-type glaciers, has fostered a multitude of glacial lakes that are highly sensitive to global climate change. Glacial lakes play a crucial role in regulating the freshwater ecosystems of the region, but they also pose a significant threat to local infrastructure and populations due to flooding caused by glacial lake outbursts. Currently, a limited amount of research has focused on the monitoring and analysis of glacial lakes in southeastern Tibet.

A major uncertainty in predicting the behaviour of marine-terminating glaciers is ice dynamics driven by non-linear calving front retreat, which is poorly understood and modelled. Using 124919 calving front positions for 149 marine-terminating glaciers in Svalbard from 1985 to 2023, generated with deep learning, we identify pervasive calving front retreats for non-surging glaciers over the past 38 years. We observe widespread seasonal cycles in calving front position for over half of the glaciers.

Soluble starch/zinc oxide nanocomposites could be promising candidates for eco-friendly antimicrobial, food packaging, and a wide range of other utilization. In order to find a new way for the preparation of this kind of nanocomposites, an efficient and energy-saving reaction for the synthesis of soluble starch/zinc oxide nanocomposites has been investigated. The reaction was implemented in a solid state at room temperature without post-reaction calcination.

Conductive hydrogels with exceptional mechanical properties have received extensive attention in flexible strain sensors. However, there is still a huge challenge in the preparation of hydrogels with high toughness, conductivity and frost resistance performance. In this study, the prepared PA-PAAM-CS (PPAC) composite hydrogels were obtained by incorporating phytic acid (PA) and chitosan (CS) into poly(acrylamide-co-stearyl methacrylate) (PAAM) polymer network.

Background: With the development of sequencing technology and the rapid increasing in the number of sequenced genomes, lineage-specific genes (LSGs) have been identified and characterized across various species. Similar to other conserved functional genes, LSGs play a crucial role in biological evolution and development. However, the understanding of LSGs remains limited.
