Validation of the in-house designed one-trial inhibitory avoidance test for two strains of adult zebrafish

The paper validates an open-source one-trial inhibitory avoidance test for two zebrafish strains, showing it effectively measures memory with a robust and long-lasting response.

Ecological genomics in the Northern krill uncovers loci for local adaptation across ocean basins

The paper analyzes Northern krill genome data to identify loci associated with local adaptation across different ocean basins.

A genomic and morphometric analysis of alpine bumblebees: ongoing reductions in tongue length but no clear genetic component

This study analyzes morphometric and genomic data from alpine bumblebees to assess ongoing morphological changes and their genetic basis, finding reduced tongue length but no clear genetic component.

Adult zebrafish anaesthesia: a study of efficacy and behavioural recovery of different anaesthetics

This study evaluates the efficacy and behavioural recovery of different anaesthetics in adult zebrafish, finding that all protocols allowed full recovery within 1 hour, with etomidate showing minor long-term behavioural effects.

Caprin-1 binding to the critical stress granule protein G3BP1 is regulated by pH

This study shows that Caprin-1 binds to G3BP1's NTF2 domain with pH sensitivity, regulating stress granule formation through a SLiM-mediated mechanism.

Robust T cell immunity in convalescent individuals with asymptomatic or mild COVID-19

The paper maps SARS-CoV-2-specific T cell responses in individuals with asymptomatic/mild COVID-19 and finds robust memory T cell responses similar to vaccines, detectable even in antibody-seronegative individuals.

Shared safety abolishes the recovery of learned threat

This study shows that combining direct and vicarious safety exposure during extinction learning abolishes threat recovery, while either alone does not.

Three-dimensional mapping identifies distinct vascular niches for myelopoiesis

This paper maps 3D vascular niches for myeloid differentiation in bone marrow, revealing distinct spatial organization of granulocyte and monocyte/dendritic cell progenitors.

High laboratory mouse pre-weaning mortality associated with litter overlap, advanced mother age, small and large litters

This study identifies risk factors for high pre-weaning mortality in laboratory mice, finding that litter overlap, advanced mother age, and extreme litter sizes increase pup death rates.

Causes of death in newborn C57BL/6J mice

This study investigates causes of death in newborn C57BL/6J mice, finding that starvation was the most common cause, followed by stillbirth.

Does training method matter?: Evidence for the negative impact of aversive-based methods on companion dog welfare

This study compares aversive- and reward-based training methods on companion dogs, finding aversive methods negatively impact short- and long-term welfare.

Enhanced instructed fear learning in delusion-proneness

This study shows delusion-prone individuals exhibit stronger instructed fear learning and lateral orbitofrontal cortex activation compared to controls, suggesting coexistence of strong top-down and weak bottom-up learning in psychosis-associated states.
