Vertical profile of snow-firn density in the vicinity of Vostok station, Central Antarctica
Лëд и снег, 2023 The density of the snow and firn thickness is one of the fundamental and most important physical properties of the polar ice sheets. The data on density is used for reconstructing the past snow accumulation rate variability based on firn core studies ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
FEBS Letters, EarlyView.We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Nonlinear threshold behavior during the loss of Arctic sea ice [PDF]
, 2009 In light of the rapid recent retreat of Arctic sea ice, a number of studies have discussed the possibility of a critical threshold (or “tipping point”) beyond which the ice–albedo feedback causes the ice cover to melt away in an irreversible process. The

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

2019 State-of-the-Science of Dispersants and Dispersed Oil (DDO) in U.S. Arctic Waters: Public Health and Food Safety [PDF]
, 2019 Chemical dispersants were employed on an unprecedented scale during the Deepwater Horizon oil spill in the Gulf of Mexico, and could be a response option should a large spill occur in Arctic waters. The use of dispersants in response to that spill raised

Anticipatory state identity: Understanding the Finnish state's approach to the Arctic
Area, 2022 AbstractThis paper is an intervention on the understanding of state identity in relation to (anticipatory) changes that have occurred, are taking place, and are expected to happen in the Arctic. Focusing specifically on the Finnish state's approach to the Arctic, we offer the concept of ‘anticipatory state identity’ in order to comprehend the role of ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Flux of nutrients from Russian rivers to the Arctic Ocean: Can we establish a baseline against which to judge future changes? [PDF]
, 2000 Climate models predict significant warming in the Arctic in the 21st century, which will impact the functioning of terrestrial and aquatic ecosystems as well as alter land‐ocean interactions in the Arctic.

United States Arctic Policy: The Reluctant Arctic Power
The School of Public Policy Publications, 2009 Although the United States is an Arctic nation, the Arctic has seldom figured prominently in US policy. In January 2009 the US released its new Arctic policy. Arctic Region Policy signals that the US is beginning to understand that the Arctic is changing in a manner that concerns its vital national interests.
