Article Synopsis
  • Serotype 3 strains of reovirus can spread to the brain and cause deadly brain infections in newborn mice.
  • Researchers found that although reovirus targets different areas of the brain, it doesn't depend on certain receptors (like SA and PirB) to infect neurons.
  • The study showed that many parts of the newborn mouse brain can be infected by reovirus, and the patterns of infection don't rely on those specific receptors.

Introduction: Caffeine is a psychostimulant possessing arousal, motor activation, and reinforcing properties, which is consumed daily by most adolescents aged 12-19 years. Although current understanding of the implications of adolescent caffeine consumption for school behaviors remains incomplete, studies have shown that in addition to acute effects of the drug, in common with other habit-forming psychoactive substances, regular use leads to physical dependence, evidenced by recurring negative withdrawal symptoms.

Methods: Employing two waves of longitudinal data, we tested the prospective association between daily caffeine use and homeroom teacher-observed self-control and problem behavior in a sample of middle-school students in 20 schools in West Virginia in the United States.

Background: The school climate concept has been promising, but has long-standing critiques that have not been adequately addressed to date. The School as a Protective Factor approach represents one attempt to offer a new approach that builds on and extends beyond the concept of school climate while addressing previously identified limitations.

Contributions To Theory: The School as a Protective Factor approach offers a new framework for conceptualizing, measuring, and establishing protective school social and learning environments that co-promote academic achievement and student health in schools, especially student mental health and substance use/abuse prevention.

The Icelandic Prevention Model (IPM) follows a systematic but flexible process of community capacity building, data collection, analysis, dissemination, and community-engaged decision-making to guide the data-informed selection, prioritization, and implementation of intervention strategies in preventing adolescent substance use. This paper describes two new evaluation tools intended to assess the: 1) integrity of IPM implementation, and 2) unique aspects of IPM implementation in different community contexts. These evaluation tools include a: 1) five-phase IPM Evaluation Framework for Assessing Value Across Communities, Cultures, and Outcomes (IPM-EF); and 2) 10-Step IPM Implementation Integrity and Consistency Assessment (IPM-IICA) that utilizes both quantitative (scored) and qualitative (narrative) data elements to characterize implementation integrity and consistency at both community coalition and school community levels.

Several treatments and preventive measures for SARS-CoV-2 were studied during the pandemic, but few focused on the neonatal gut microbiome and its role in the setting of COVID-19. This case report is unique because it describes the gut microbiomes of a mother and her newborn, who both contracted COVID-19 shortly after the baby's birth. In this prospective study, on day 11 postpartum, both the newborn and mother (38 years old), of white race/ethnicity, were exposed to a COVID-19-positive person.

Detecting introgression between closely related populations or species is a fundamental objective in evolutionary biology. Existing methods for detecting migration and inferring migration rates from population genetic data often assume a neutral model of evolution. Growing evidence of the pervasive impact of selection on large portions of the genome across diverse taxa suggests that this assumption is unrealistic in most empirical systems.

  • Alcohol is a big problem for people's health in the U.S., especially for those who don't have stable homes, and this study looks into how to help them with their drinking issues.
  • Researchers talked to 25 people living without stable housing who drink heavily, finding out that not having a home causes stress, which leads them to drink more.
  • To help these individuals, treatment options need to be more flexible and include both stopping drinking and reducing harm, along with providing secure housing to help solve the root of the problem.

Naked mole-rats (NMRs) are best known for their extreme longevity and cancer resistance, suggesting that their immune system might have evolved to facilitate these phenotypes. Natural killer (NK) and T cells have evolved to detect and destroy cells infected with pathogens and to provide an early response to malignancies. While it is known that NMRs lack NK cells, likely lost during evolution, little is known about their T-cell subsets in terms of the evolution of the genes that regulate their function, their clonotypic diversity, and the thymus where they mature.

Machine learning has increasingly been applied to a wide range of questions in phylogenetic inference. Supervised machine learning approaches that rely on simulated training data have been used to infer tree topologies and branch lengths, to select substitution models, and to perform downstream inferences of introgression and diversification. Here, we review how researchers have used several promising machine learning approaches to make phylogenetic inferences.

Mounting evidence suggests that environmentally induced epigenetic inheritance occurs in mammals and that traits in the progeny can be shaped by parental environmental experiences. Epidemiological studies link parental exposure to environmental toxicants, such as the pesticide DDT, to health phenotypes in the progeny, including low birth and increased risk of chronic diseases later in life. Here, we show that the progeny of male mice exposed to DDT in the pre-conception period are born smaller and exhibit sexual dimorphism in metabolic function, with male, but not female, offspring developing severe glucose intolerance compared to controls.
