Projections of ice sheet behavior hinge on how ice flow velocity evolves and the extent to which marine-based grounding lines are stable. Ice flow and grounding line retreat are variably governed by the coupling between the ice and underlying terrain. We ask to what degree catchment-scale bed characteristics determine ice flow and retreat, drawing on paleo-ice sheet landform imprints from 99 sites ...

Hamsuns roman Victoria er et trekantdrama mellom møllerens sønn Johannes, Victoria på godset, og «byherren» og offiseren Otto. Det er samtidig en roman om Johannes' utvikling som forfatter. Artikkelen undersøker forholdet mellom Johannes som en skarp iakttager av foreteelser i naturen – med lukt og synsinntrykk, lyd og taktile fornemmelser – og hans imaginasjonskraft, hans drømmer og visjoner. ...

High levels of organochlorines (OCs) have been measured in arctic char (<i>Salvelinus alpinus</i>) from Lake Ellasjøen on Bjørnøya, Norway (74.30°N, 19.0°E). In a nearby lake, Laksvatn, the OC-levels in arctic char were low. A previous study has shown that char from Ellasjøen had significantly higher levels of DNA double strand breaks (DSBs) than char from Lake Laksvatn. Even though there is increasing ...

When analysing a large cohort of <i>Staphylococcus haemolyticus</i>, using whole-genome sequencing, five human isolates (four from the skin and one from a blood culture) with aberrant phenotypic and genotypic traits were identified. They were phenotypically similar with yellow colonies, nearly identical 16S rRNA gene sequences and initially speciated as <i>S. haemolyticus</i> based on 16S rRNA gene ...

Microscopy is possibly the best tool we have to peer into the microscopic world to enhance our understanding of the usually invisible, but highly complex and vital events every moment taking place inside living cells. Microscopy is brilliant, but also has its physical constraints and technical limitations. Technical advances have in the last decade pushed optical microscopy past physical limits ...

Optimizing drug therapies for any disease requires a solid understanding of pharmacokinetics (the drug concentration at a given time point in different body compartments) and pharmacodynamics (the effect a drug has at a given concentration). Mathematical models are frequently used to infer drug concentrations over time based on infrequent sampling and/or in inaccessible body compartments. Models are ...

Trondheims-dialekten har tradisjonelt tre grammatiske kjønn: hankjønn, hunkjønn, og intetkjønn. Denne artikkelen presenterer resultater fra to eksperimenter som viser at hunkjønn står svakere i denne dialekten enn tidligere antatt. Resultatene tyder på at dialekten er i ferd med å utvikle et togenussystem, der den ubestemte artikkelen for hunkjønn og hankjønn har falt sammen. Vi ser tydelige forskjeller ...

This paper presents findings from an on-going international study of Early Childhood(EC) teachers’ and children’s use of internet-connected toys (IoToys) to understand possibilities for developing children’s cognitive capacities (e.g., creativity, inquiry, engineering design thinking). The study employed a Design Based Research (DBR) method, where teachers intentionally plan and deliver technologically ...

In recent years, Arctic and sub-Arctic fish communities have shown extensive reorganization on shelves and in shallow waters, but little is known about the ecological impact of environmental changes in deeper waters. We examined temporal changes (1998-2016) in fish diversity and community structure based on research survey data from East Greenland, over a depth gradient spanning 400 to 1500 m. A ...

The second largest sink for atmospheric methane (CH₄) is atmospheric methane oxidizing-bacteria (atmMOB). How atmMOB are able to sustain life on the low CH₄ concentrations in air is unknown. Here, we show that during growth, with air as its only source for energy and carbon, the recently isolated atmospheric methane-oxidizer <i>Methylocapsa gorgona</i> MG08 (USCα) oxidizes three ...
