Polar Research evolves, and Norway and the IPY
, 2007 March marks the start of the International Polar Year (IPY) and I am very pleased to announce on this occasion that we’ve joined hands with Blackwell Publishing, which will henceforth publish the journal while editorial control remains with the editorial

A generalized inequality for the polar derivative of a polynomial
, 2013 In this paper, we extend a result recently proved by Liman et al. (Complex Anal. Oper. Theory 6:1199-1209, 2012. doi:10.1007/s11785-010-0120-3) to the polar derivative of a polynomial and thereby obtain some more general results for polynomials with ...

Molecular Oncology, EarlyView.Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...

Revisiting perceptions and evolving culture: a community dialogue on women in polar research
, 2018 Women have made outstanding contributions to polar research in recent decades, though full engagement may be hindered by persistent inequities, including notably the prevalence of workplace harassment.

Polar bear predation on barrier island bird colonies in Arctic Alaska increases with sea-ice decline
Anthropogenic carbon emissions are warming the Arctic, disrupting ecosystems, and changing the behaviour and interactions of their component species. As summer sea ice diminishes, polar bears (Ursus maritimus) are losing access to traditional seal prey ...

, 2009 During recent fieldwork in Svalbard, a well preserved subfossil left mandible of a polar bear (Ursus maritimus Phipps, 1774) was discovered. A 14C age determination shows that it is older than 45 Ky (kilo-years), and an age determination with infrared ...

Modelling polar bear maternity den habitat in east Svalbard
, 2020 We evaluated a novel tool that predicts possible maternity den habitat of the polar bear (Ursus maritimus) based on a physical snow transport model, a digital terrain model and weather data.

Circularly Polarized Luminescence in Helicene and Helicenoid Derivatives [PDF]
, 2020 In this chapter, we discuss the circularly polarized luminescence (CPL) of helicene and helicenoid derivatives. The organic helicenic derivatives are classified according to the type of atom (heteroatom or carbon) incorporated within the helical backbone.

Molecular Oncology, EarlyView.Partial inhibition of focal adhesion kinase (FAK) can paradoxically promote tumor growth, rather than simply producing a weaker antitumor effect than that observed with strong FAK suppression. In breast cancer and melanoma models, targeting p110δ PI3K, particularly in macrophages, counteracted these tumor‐promoting effects, highlighting the importance ...

Review of The expeditions of the first International Polar Year 1882–83, by William Barr
, 2009 It is probably safe to assume that no readers of Polar Research are unaware that we have just come through a fourth International Polar Year (IPY). All science is, or should be, based on the previous achievements of others, and thus the experiences and ...
