FEBS Letters, Volume 599, Issue 8, Page 1113-1121, April 2025.The glacier ice worm Mesenchytraeus solifugus survives year‐round at 0 °C. Its ATP6 subunit, which forms a regulatory component of the proton pore in mitochondrial ATP synthase, has a carboxy‐terminal extension not found in any other organism examined to date. Here, we show that fusion of this extension to the homologous AtpB protein in E. coli results

The Seismicity of the Arctic [PDF]
Seismological Research Letters, 1929 The paper (to be published in full in J. R. Astr. Soc. Can.) presents an analysis of the data compiled at the Dominion Observatory, Ottawa, Canada, in connection with the series of publications on the “Location of epicenters” for the years 1911–1927, inclusive, together with that given in the series of “International summaries” published by Prof. H. H.

Science of The Total Environment, 2022 Anthropogenic mercury (Hg) undergoes long-range transport to the Arctic where some of it is transformed into methylmercury (MeHg), potentially leading to high exposure in some Arctic inhabitants and wildlife. The environmental exposure of Hg is determined not just by the amount of Hg entering the Arctic, but also by biogeochemical and ecological ...

FEBS Letters, Volume 599, Issue 9, Page 1222-1235, May 2025.The S1025 peptide is the major antidote to the YrzI toxin, which we renamed here as SpyT (Small Peptide YrzI Toxin) and SpyA (Small Peptide YrzI Antitoxin) (1). Degradation of the toxin–antitoxin spyTA mRNA, either by a translation‐dependent cleavage by the endoribonuclease Rae1 (2) or by direct attack by 3′‐exoribonucleases (3), also contributes to ...

Nature, 1898 OF the wild bees of Alaska nothing is known, except that several species of humble-bees (Bombus) are common. Consequently, when Mr. Trevor Kincaid wrote me last year that he was going to Alaska, and would collect bees, I was expecting to see, on his return, quite a new bee-fauna.

Identification of novel small molecule inhibitors of ETS transcription factors
FEBS Letters, EarlyView.ETS transcription factors play an essential role in tumourigenesis and are indispensable for sprouting angiogenesis, a hallmark of cancer, which fuels tumour expansion and dissemination. Thus, targeting ETS transcription factor function could represent an effective, multifaceted strategy to block tumour growth. The evolutionarily conserved E‐Twenty‐Six

The arctic curve of the domain-wall six-vertex model [PDF]
J. Stat. Phys. 138 (2010), 662-700, 2009 The problem of the form of the `arctic' curve of the six-vertex model with domain wall boundary conditions in its disordered regime is addressed. It is well-known that in the scaling limit the model exhibits phase-separation, with regions of order and disorder sharply separated by a smooth curve, called the arctic curve.

Cystic echinococcosis in the Arctic and Sub-Arctic
Parasitology, 2003 The northern biotype ofEchinococcus granulosusoccurs throughout the holarctic zones of tundra and taiga, from eastern Fennoscandia to the Bering Strait in Eurasia and in North America from arctic Alaska approximately to the northern border of the United States.
