Senescence is a tripartite cellular phenotype characterized by permanent growth arrest, resistance to apoptosis, and high secretory activity. Besides its physiological role in embryonic development and pathophysiological contribution to age-related tissue degeneration, in the context of tumor development senescence is an important suppressor mechanism, that counteracts accelerated proliferation. Among the many stressors that i...

The Arctic climate is changing rapidly. The warming and resultant longer open water periods suggest a potential for expansion of marine vegetation along the vast Arctic coastline. We compiled and reviewed the scattered time series on Arctic marine vegetation and explored trends for macroalgae and eelgrass ( Zostera marina ). We identified a total of 38 sites, distributed between Arctic coastal regions in Alaska, Canada, Greenl...

The performance of the gas diffusion electrode (GDE) is crucial for technical processes like chlorine–alkali electrolysis. The function of the GDE is to provide an intimate contact between gaseous reactants, the solid catalyst, and the liquid electrolyte. To accomplish this, the GDE is composed of wetting and non-wetting materials to avoid electrolyte breakthrough. Knowledge of the spatial distribution of the electrolyte in th...

The Western Antarctic Peninsula (WAP), one of the most productive regions of the Southern Ocean, is currently undergoing rapid environmental changes such as ocean acidification (OA) and increased daily irradiances from enhanced surface‐water stratification. To assess the potential for future biological CO 2 sequestration of this region, we incubated a natural phytoplankton assemblage from Ryder Bay, WAP, under a range of pCO 2...
