The calcifuge behaviour of Viscaria vulgaris

Soil factors responsible for the inability of Visearía vulgaris to colonize or survive on calcareous soils in Scandinavia were studied using experiments with plant establishment from seeds and re-establishment of mature plants, in soils of naturally differing or artificially varied chemical properties. Limestone soil proved less suitable for re-establishment of mature plants, and establishment fro

Speaking Beyond Earth : Perspectives on Messaging Across Deep Space and Cosmic Time

Since the dawn of the Space Age, small cohorts of humanity have broadcast signals towards other stars, fabricated “space-time capsules” to “speak for Earth” aboard interstellar probes, deposited collections of “space oddities” on other astronomical bodies, and permanently incised the memory of our species across the deep-time legacy of the Sol System. Many of these purposeful “messages” are the co

Oral contraceptive use in women with spina bifida in Sweden

BACKGROUND: Thanks to improved medical care, individuals with spina bifida (SB) live well into adulthood and go through the process of reproductive maturation and the development of sexual desires. However, access to reproductive counselling and contraceptive use has been reported to be lower for women with physical and intellectual disabilities compared to the general population.OBJECTIVE: We inv

The impact of health insurance on maternal and reproductive health service utilization and financial protection in low- and lower middle-income countries : a systematic review of the evidence

Background: Low- and middle-income countries have committed to achieving universal health coverage (UHC) as a means to enhance access to services and improve financial protection. One of the key health financing reforms to achieve UHC is the introduction or expansion of health insurance to enhance access to basic health services, including maternal and reproductive health care. However, there is a

Workplace interventions to reduce the risk of SARS-CoV-2 infection outside of healthcare settings

Background: Although many people infected with SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) experience no or mild symptoms, some individuals can develop severe illness and may die, particularly older people and those with underlying medical problems. Providing evidence-based interventions to prevent SARS-CoV-2 infection has become more urgent with the potential psychological toll i

Diversity and Evolution of Frog Visual Opsins : Spectral Tuning and Adaptation to Distinct Light Environments

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

Exploring pandemic holiday practices: Meaning, experience and aspiration

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

Ten-year follow-up of fracture risk in a systematic population-based screening program : the risk-stratified osteoporosis strategy evaluation (ROSE) randomised trial

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

Lipid nanoparticles for local delivery of mRNA to the respiratory tract : Effect of PEG-lipid content and administration route

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

Effectiveness of internet-delivered cognitive behavioural therapy for anxiety and obsessive-compulsive disorders within routine clinical care in rural Sweden

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

Validation of the Scandinavian guidelines for minor and moderate head trauma in children : protocol for a pragmatic, prospective, observational, multicentre cohort study

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

A reply to Nieberding and Holveck : Beyond experimental design and proximate mechanisms - mate choice in the face of sexual conflict

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

Common practice solvent extraction does not reflect actual emission of a sex pheromone during butterfly courtship

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

Young male mating success is associated with sperm number but not with male sex pheromone titres

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

Flying insect swarms

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.

Superplot3d : An open source GUI tool for 3d trajectory visualisation and elementary processing

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
