Urban living can rescue Darwin's finches from the lethal effects of invasive vampire flies.

Human activity changes multiple factors in the environment, which can have positive or negative synergistic effects on organisms. However, few studies have explored the causal effects of multiple anthropogenic factors, such as urbanization and invasive species, on animals and the mechanisms that mediate these interactions. This study examines the influence of urbanization on the detrimental effect of invasive avian vampire flies (Philornis downsi) on endemic Darwin's finches in the Galápagos Islands.

Medicaid Expansion and Perinatal Health Outcomes: A Quasi-Experimental Study.

Objective: There has been little evidence of the impact of preventive services during pregnancy covered under the Affordable Care Act (ACA) on birthing parent and infant outcomes. To address this gap, this study examines the association between Medicaid expansion under the ACA and birthing parent and infant outcomes of low-income pregnant people.

Methods: This study used individual-level data from the 2004-2017 annual waves of the Pregnancy Risk Assessment Monitoring System (PRAMS).

Digest: A sex chromosome driver without a sperm deficit.

Meiotic drivers that act during spermatogenesis derive a transmission advantage by disabling sperm that do not carry the driver, often leading to substantially reduced overall sperm number and function. A new study by Bates et al. shows no sperm deficit for a driver in a stalk-eyed fly, in contrast to a related species.

Digest: Rare male offspring highlight an alternative pathway to obligate asexuality.

Obligate asexuality has arisen many times in eukaryotes, often related to the disrupted function of the core meiotic machinery. For obligately asexual lineages that evolve from facultatively asexual ancestors, there exists another possibility, namely altered regulation of preexisting asexual reproductive processes to produce obligate asexuality. These different pathways leave different signatures in properties of meiosis and recombination that could provide insights into the origin of asexuality.

Digest: Mating systems, intragenomic conflict, and speciation.

Conflict over the degree of maternal investment in an offspring can exist between an offspring's maternally inherited and paternally inherited alleles. Such conflict is not expected under self-fertilization. A new study led by Rifkin and Ostevik suggests that divergence in the degree of conflict between closely related outcrossing and selfing species can lead to aberrant early development of hybrids in morning glories.

Data-Driven Determination of the Light-Quark Connected Component of the Intermediate-Window Contribution to the Muon g-2.

We present the first data-driven result for a_{μ}^{win,lqc}, the isospin-limit light-quark connected component of the intermediate-window Hadronic-vacuum-polarization contribution to the muon anomalous magnetic moment. Our result, (198.8±1.

Feeding and Swallowing Outcomes in Children Who Use Long-Term Ventilation: A Scoping Review.

The last two decades have seen increasing use of long-term ventilation (LTV) as an intervention in childhood. Children who use LTV have many risk factors for feeding and swallowing difficulties, including their underlying respiratory and/or neurological etiology, long hospitalizations, medical interventions, and limited exposure to oral feeding experiences. This review aimed to answer two questions: 1) 'What specific swallowing and feeding characteristics do these children experience?'; and 2) 'What impacts do these swallowing and feeding characteristics have on health status and quality of life?'.

Content Coverage as a Persistent Exclusionary Practice: Investigating Perspectives of Health Professionals on the Influence of Undergraduate Coursework.

STEM undergraduates navigate lengthy sequences of prerequisite courses covering volumes of science content. Given that these courses may contribute to attrition and equity gaps in STEM, research is needed to test the assumption that prerequisite content benefits students in their future studies and careers. We investigated the relevance of prerequisite course content for students' careers through semistructured interviews with practicing nurses regarding their undergraduate anatomy and physiology (A&P) courses.

A Literature Review on the Effects of Exergames on Executive Function in Youth.

Exergames (video games that promote cognitive and physical activity simultaneously) benefit executive function in elderly populations. It has been suggested that exergames may induce larger effects than cognitive or exercise training alone, but few reviews have synthesized the causal factors of exergames on executive function from experimental research with youth. This review investigates (1) the various types of exergames and associated comparison conditions (2) the executive function outcome assessments commonly utilized in exergame research with youth (3) the efficacy of exergames by evaluating experimental studies that compared exergaming to cognitive, exercise, and passive control conditions inclusive of effect sizes and (4) the potential mechanisms underlying the changes in executive function induced from exergames.

"Competitive" food and beverage policies and weight status: A systematic review of the evidence among sociodemographic subgroups.

Prior studies identified variable associations between competitive food and beverage policies (CF&B) and youth obesity, potentially due to differences across population subgroups. This review summarizes the evidence on associations between CF&B policies and childhood obesity within gender, grade level/ age, race/ethnicity, and/or socioeconomic levels. PubMed, EMBASE, CINAHL, and ERIC database searches identified studies published in English in Canada and the United States between January 1, 2000, and February 28, 2022.

Trust and perceived mental health access: Exploring the relationship between perceived access barriers and veteran-reported trust.

The importance of patients' trust in health care is well known. However, identifying actionable access barriers to trust is challenging. The goal of these exploratory analyses is to identify actionable access barriers that correlate with and predict patients' lack of trust in providers and in the health care system.

The ability of typically developing 2-3 year olds to infer the control mechanism for eye-gaze technology and the impact of causal language instruction.

Purpose: Little is known about how children learn to control eye-gaze technology, and clinicians lack information to guide decision-making. This paper examines whether typically developing 2-3 year olds can infer for themselves the causal mechanisms by which eye-gaze technology is controlled, whether a teaching intervention based on causal language improves performance and how their performance compares to the same task accessed via a touchscreen. Typically developing children's (n = 9, Mean Age 28.

Primary Care Physicians' and Hospitalists' Experience with Advance Care Planning with South Asian Canadian Older Adults before and during COVID-19.

Few older adults discuss their end-of-life care wishes with their physician, and even fewer minorities do this. We explored physicians' experience with advance care planning (ACP) including the barriers/facilitating factors encountered when initiating/conducting ACP discussions with South Asians (SA), one of Canada's largest minorities. Eleven primary care physicians (PC) and 11 hospitalists with ≥ 15 per cent SA patients ≥ 55 years of age were interviewed: 10 in 2020, 12 in 2021.

Genome assemblies of two species of porcelain crab, Petrolisthes cinctipes and Petrolisthes manimaculis (Anomura: Porcellanidae).

Crabs are a large subtaxon of the Arthropoda, the most diverse and species-rich metazoan group. Several outstanding questions remain regarding crab diversification, including about the genomic capacitors of physiological and morphological adaptation, that cannot be answered with available genomic resources. Physiologically and ecologically diverse Anomuran porcelain crabs offer a valuable model for investigating these questions and hence genomic resources of these crabs would be particularly useful.

Stimulus-Elicited Involuntary Cognition: Boundary Conditions and Systematic Effects.

For decades, researchers have been presenting participants with stimuli and instructing the participants not to respond to the stimuli in some way. Today, researchers are studying the effects that such stimuli have, not only on behavior, but on conscious experience. To this end, researchers have used several laboratory tasks, including the reflexive imagery task (RIT).

Health Equity: Access to Outdoor Fitness Equipment.

Adequate outdoor fitness equipment is essential for physical activity in lower income neighborhoods. San Francisco, CA, in the United States will be highlighted as a city with a large death rate, which could be improved by installing, promoting, and allowing access to fitness equipment. More than 2700 accidental overdose deaths have occurred since the year 2019, with a projected cumulative death rate expected to exceed 3000 human lives by the end of 2023.

Exploring torsional conformer space with physical prior mean function-driven meta-Gaussian processes.

We present a novel approach for systematically exploring the conformational space of small molecules with multiple internal torsions. Identifying unique conformers through a systematic conformational search is important for obtaining accurate thermodynamic functions (e.g.

Serotype 3 Antibody Response and Antibody Functionality Compared to Serotype 19A Following 13-Valent Pneumococcal Conjugate Immunization in Children.

Background: Prevention of infections in children vaccinated with 13-valent pneumococcal conjugate vaccine (PCV13) may be less effective against serotype 3 than 19A.

Objective: The aim of this study was to to determine differences in IgG and functional antibody for serotype 3 versus 19A following PCV13 immunization, in IgG antibody levels induced by PCV13 compared to naturally-induced immunity, and assess effectiveness of PCV13 against serotype 3 and 19A in prevention of acute otitis media (AOM) and colonization among 6-36-month-old children.

Methods: Samples were from a prospective, longitudinal, observational cohort study conducted in Rochester, NY.

Common ground in AAC: how children who use AAC and teaching staff shape interaction in the multimodal classroom.

Children who use augmentative and alternative communication (AAC) are multimodal communicators. However, in classroom interactions involving children and staff, achieving mutual understanding and accomplishing task-oriented goals by attending to the child's unaided AAC can be challenging. This study draws on excerpts of video recordings of interactions in a classroom for 6-9-year-old children who used AAC to explore how three child participants used the range of multimodal resources available to them - vocal, movement-based, and gestural, technological, temporal - to shape (and to some degree, co-control) classroom interactions.

Chronological and genetic analysis of an Upper Palaeolithic female infant burial from Borsuka Cave, Poland.

Six infant human teeth and 112 animal tooth pendants from Borsuka Cave were identified as the oldest burial in Poland. However, uncertainties around the dating and the association of the teeth to the pendants have precluded their association with an Upper Palaeolithic archaeological industry. Using <67 mg per tooth, we combined dating and genetic analyses of two human teeth and six herbivore tooth pendants to address these questions.

Trajectories of sociopolitical stress during the 2020 United States presidential election season: Associations with psychological well-being, civic action, and social identities.

Sociopolitical stress arises in reaction to awareness of, exposure to, and/or involvement in political events. Among a longitudinal cohort of 628 college students from 10 universities across the U.S.

Effect of baby swimming lessons on infants' avoidance of bodies of water.

Despite the popularity of infant swimming programs, no evidence exists to determine whether they influence infants' judgments and behavior when confronted with bodies of water. We conducted two separate studies examining if the total number of swimming sessions an infant participated in predicted whether they avoided a body of water they could enter via an edge (Study 1-Water Cliff: n = 101 infants) or a slope (Study 2-Water Slope: n = 77 infants). The results revealed a significant interaction between number of sessions and type of entry into the water.

Telomere dynamics and reproduction.

The oocyte, a long-lived, postmitotic cell, is the locus of reproductive aging in women. Female germ cells replicate only during fetal life and age throughout reproductive life. Mechanisms of oocyte aging include the accumulation of oxidative damage, mitochondrial dysfunction, and disruption of proteins, including cohesion.
