Visual systems adapt to different light environments through several avenues including optical changes to the eye and neurological changes in how light signals are processed and interpreted. Spectral sensitivity can evolve via changes to visual pigments housed in the retinal photoreceptors through gene duplication and loss, differential and coexpression, and sequence evolution. Frogs provide an ex

During Covid-19 holiday travel became shorter in distance and more surface-based, presenting an unusual opportunity to explore people's experiences of less carbon-intensive holiday travel. In this paper, survey and interview data are used to investigate pandemic holiday practices, exploring how meanings and aspirations relate to travel distance and mode. The findings illustrate the complexity of m

Background: Osteoporotic fractures pose a growing public health concern. Osteoporosis is underdiagnosed and undertreated, highlighting the necessity of systematic screening programs. We aimed to evaluate the effectiveness of a two-step population-based osteoporotic screening program. Methods: This ten-year follow-up of the Risk-stratified Osteoporosis Strategy Evaluation (ROSE) randomized trial te

Design of inhalable mRNA therapeutics is promising because local administration in the respiratory tract is minimally invasive and induces a local response. However, several challenges related to administration via inhalation and respiratory tract barriers have so far prevented the progress of inhaled mRNA therapeutics. Here, we investigated factors of importance for lipid nanoparticle (LNP)-media

Few studies have evaluated the implementation of ICBT in regular child and adolescent mental health services (CAMHS). This study aimed to explore the acceptability, feasibility, and effectiveness of ICBT for children and adolescents with anxiety disorders and obsessive-compulsive disorder (OCD) within a rural CAMHS. The study also explored outcome predictors and long-term outcomes. Eighty-three pa

Introduction Mild traumatic brain injury is common in children and it can be challenging to accurately identify those in need of urgent medical intervention. The Scandinavian guidelines for management of minor and moderate head trauma in children, the Scandinavian Neurotrauma Committee guideline 2016 (SNC16), were developed to aid in risk stratification and decision-making in Scandinavian emergenc

We summarise our work on male mating behaviour in the tropical butterfly Bicyclus anynana, responding to the commentary provided by Nieberding and Holveck. We acknowledge that our laboratory studies are not free of shortcomings and potential caveats, though we attempted to address or highlight these within each paper. The concerns raised seem to stem mainly from different notions with respect to t

Olfactory communication can be of critical importance for mate choice decisions. Lepidoptera are key model systems for understanding olfactory communication, particularly considering sex pheromone signaling in the context of sexual selection. Solvent extraction or rinsing of pheromone-producing structures is a widespread method for quantifying sex pheromones, but such measures reflect what is stor

Background: Intraspecific communication is of crucial importance throughout the animal kingdom and may involve a combination of visual, gustatory, olfactory and acoustic cues. Variation in male sex pheromone amount and composition may convey important information to female conspecifics, for instance on species identity or age. However, whether increased male pheromone titres are associated with fi

Dublon and Sumpter give a concise and access guide to flying insect swarms, some of which, such as the crop-eating locust swarms, are pests, while others, such as honeybee swarms and migrating butterflies, are beneficial.

When acquiring simple three-dimensional (3d) trajectory data it is common to accumulate large coordinate data sets. In order to examine integrity and consistency of object tracking, it is often necessary to rapidly visualise these data. Ordinarily, to achieve this the user must either execute 3d plotting functions in a numerical computing environment or manually inspect data in two dimensions, plo

In a laboratory bioassay, adult female Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) spent more time near filter paper disks that had been exposed to adult males than near unexposed disks; this effect was not observed on disks exposed to adult females. The response could only partly be explained by the known male-produced aggregation pheromone, neryl (S)-2-methylbutanoate, sugges

The aggregation pheromone of the western flower thrips, Frankliniella occidentalis (Thysanoptera: Thripidae), has previously been identified as the monoterpenoid ester neryl (S)-2-methylbutanoate. It attracts both male and female adults to traps in commercial glasshouses. In this paper, we investigate the rates of production of this compound at two male densities and in the presence or absence of

Background: Chronic lung disease (CLD) occurs frequently in preterm infants and is associated with respiratory morbidity. Bronchodilators have the potential effect of dilating small airways with muscle hypertrophy. Increased compliance and tidal volume, and decreased airway resistance, have been documented with the use of bronchodilators in infants with CLD. Therefore, bronchodilators are widely c

Feminist solidarity transcends borders. Yet, there is a tension arising from an entrenched view of feminism as inherently “Western,” originating in Europe and exported to the rest of the world. Building on fieldwork and interviews with Tunisian and Egyptian feminist activists, this paper challenges this perception by looking at how feminist activists relate to their diverging histories, and how fe

Objective: To explore factors associated with change in empowerment in patients that have participated in a 3-month Supported Osteoarthritis Self-Management Program (SOASP). Further, to evaluate empowerment in the longer term. Design: An explorative analysis including patients from a cohort study conducted in primary healthcare in Sweden was performed. Univariable linear regression models were per

Objectives: Patients with SLE have an increased risk of comorbidities and impaired survival. We aimed to assess whether various thresholds of oral CS (OCS) can predict development of infections, comorbidities, malignancies and survival in SLE using data from national health registries in Sweden. Methods: All incident SLE cases, age >18 years, in Sweden (n ¼ 5309) between 2005 and 2020 and matched
