Interannual and seasonal variability of Arctic sea ice extent according to satellite observations
The interannual and seasonal changes of Arctic sea ice extent according to satellite observations from 1978–2018 are analyzed. Steady reduction in the sea ice cover over the research period is reported.

Arctic Sea Ice Extent Plummets in 2007 [PDF]
Arctic sea ice declined rapidly to unprecedented low extents in the summer of 2007, raising concern that the Arctic may be on the verge of a fundamental transition toward a seasonal ice cover.Arctic sea ice extent typically attains a seasonal maximum in March and minimum in September.

We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Extent and thickness of the Labrador ice-sheet [PDF]
Introduction The Labrador ice-sheet did not cover the whole of eastern America north of New York, since the Torngat region, in northeastern Labrador, and the Shickshock Mountains, in Gaspe, escaped and remained as driftless areas. On the other hand, in places the ice-sheet passed beyond the present eastern edge of the continent, covering part of the ...

Record Early Sea Ice Loss in Southeastern Hudson Bay in Spring 2024
Hudson Bay seasonal sea‐ice cover plays an important role in marine ecosystems and human activities. Spring 2024 witnessed a uniquely early southeastern opening, leading to basin‐wide sea ice extent falling 5σ below the 1979–2023 average.

In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Ice extent trends in the Barents and Kara Seas during recent climate change
Certain areas of the Arctic region, primarily the Barents and Kara Seas, have high resource potential. This is the place where hydrocarbon deposits are explored and developed, and where the main transport corridor of the Northern Sea Route begins.

Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
