Nitrogen Fixation Potential in Bathypelagic Sediment of the Ice-Covered Arctic Ocean Revealed Through Long-Term Stable Isotope Incubations.

Due to climate change, sea ice more commonly retreats over the shelf breaks in the Arctic Ocean, impacting sea ice-pelagic-benthic coupling in the deeper basins. Nitrogen fixation (the reduction of dinitrogen gas to bioavailable ammonia by microorganisms called diazotrophs) is reported from Arctic shelf sediments but is unknown from the Arctic deep sea. We sampled five locations of deep-sea (900-1500 m) surface sediments in the central ice-covered Arctic Ocean to measure potential nitrogen fixation through long-term (> 280 days) stable-isotope (N) incubations and to study diazotroph community composition through amplicon sequencing of the functional marker gene nifH.

Constructing a bridge between functioning of oscillatory neuronal networks and quantum-like cognition along with quantum-inspired computation and AI.

Quantum-like (QL) modeling, one of the outcomes of the quantum information revolution, extends quantum theory methods beyond physics to decision theory and cognitive psychology. While effective in explaining paradoxes in decision making and effects in cognitive psychology, such as conjunction, disjunction, order, and response replicability, it lacks a direct link to neural information processing in the brain. This study bridges neurophysiology, neuropsychology, and cognitive psychology, exploring how oscillatory neuronal networks give rise to QL behaviors.

Stepwise genome evolution from a facultative symbiont to an endosymbiont in the N-fixing diatom-Richelia symbioses.

A few genera of diatoms that form stable partnerships with N-fixing filamentous cyanobacteria Richelia spp. are widespread in the open ocean. A unique feature of the diatom-Richelia symbioses is the symbiont cellular location spans a continuum of integration (epibiont, periplasmic, and endobiont) that is reflected in the symbiont genome size and content.

REAGERA-dementia: study protocol for the validation of screening instruments to detect abuse of people with dementia.

Background: Abuse of older people is common and people living with dementia are at high risk of being subjected to abuse. This study protocol describes the development and procedure to test the validity of two new screening instruments to detect abuse of people with dementia: 1) The REAGERA-S20, intended to be answered by people with dementia themselves, including questions about their abusive experiences, and 2) The REAGERA - N, intended to be answered by the next of kin of people with dementia, including questions about their own exposure to abuse, their own perpetration as well as the witnessing of abusive acts. In addition, the Risk on Elder Abuse and Mistreatment Instrument (REAMI) is translated into Swedish within the project and will be validated.
