Including debris cover effects in a distributed model of glacier ablation [PDF]

, 2012
Distributed glacier melt models generally assume that the glacier surface consists of bare exposed ice and snow. In reality, many glaciers are wholly or partially covered in layers of debris that tend to suppress ablation rates.

Introducing Borsantrazole: A Trifunctional Boron‐Based Pyrazole That Extends the Lifespan of Amyotrophic Lateral Sclerosis Mice

Advanced Science, EarlyView.
Herein we report a boron‐based pyrazole, (Borsantrazole ‐ a small molecule that selectively targets oxidative stress) that significantly increases survival, reduces weight loss, delays disease onset, and affects global protein changes in the SOD1‐G37R mouse model of ALS.

Completing the World Glacier Inventory [PDF]

Annals of Glaciology, 2009
AbstractAn inventory of the surface area and volume of the world’s glaciers, outside Greenland and Antarctica, was part of the International Hydrological Decade (1965–74). It was considered essential to an understanding of the role played by glaciers in the hydrological cycle and was to be repeated every 50 years to detect change.

Intra-annual and intra-seasonal flow dynamics of a High Arctic polythermal valley glacier [PDF]

, 2002
Measurements of surface dynamics on polythermal John Evans Glacier, Nunavut, Canada, over two winter periods and every 7-10 days throughout two melt seasons (June-July 2000, 2001) provide new insight into spatio-temporal patterns of High Arctic glacier ...

Transposable Element–Driven PIEZO Mutation Enhances Locust Flight in Plateau Hypoxia

Advanced Science, EarlyView.
Why transposable elements (TEs) persisted or expanded in genomes remains a mystery. Using integrated analysis of TE macro‐ and microevolution in locusts, our results showed that thousands of TE insertions promoted widespread adaptive variation. Subfamilies of candidate adaptive TEs amplified and reshaped species‐level genomic architecture.

Glacier Inventory in Chile: current status and recent glacier variations [PDF]

Annals of Glaciology, 1995
The glacier inventory in Chile covers all the arid north of the country (18° to 33° S) and the central part down to the lake district (33° to 41° 30′ S) except for the Río Maule and Río Itata basins (35° to 37° S). The most glaciated region of Chile is Patagonia, characterized by a wet climate, but glacier data are lacking over vast areas of this ...

Gαi1/3 Are Essential for BMP2‐Induced Osteogenesis by Bridging BMP Receptors to the Gab1 Signaling Complex

Advanced Science, EarlyView.
The Gαi1/3 protein is a crucial connecting protein closely related to the signal transduction process of bone formation‐related cytokines such as BMP2. Gαi1/3 mediates downstream signaling pathways such as Smads and MAPK by binding to adaptor proteins like Gab1, thereby promoting the osteogenic effect of BMSCs.

Multitemporal glacier inventory revealing four decades of glacier changes in the Ladakh region

Earth System Science Data, 2022
Abstract. Glacier inventories, and changes therein, play an important role in understanding glacier dynamics and water resources over larger regions. In this study, we present a Landsat-based multi-temporal inventory of glaciers in four Upper Indus sub-basins and three internal drainage basins in the Ladakh region for the years 1977, 1994, 2009 and ...

Covalently Linked Peptides and Membrane Potential Enable CyaA Segment Translocation

Advanced Science, EarlyView.
Using a newly developed Droplet Interface Bilayer‐Pipette assay, the authors show that two segments of the CyaA toxin cross membranes by distinct mechanisms. One segment translocates spontaneously, whereas the translocation of the other depends on membrane potential.
