A longitudinal examination of factors predicting maternal permissiveness toward underage student drinking across the first three years of college.

Addict Behav

January 2025

Edna Bennett Pierce Prevention Research Center, The Pennsylvania State University, University Park, PA, USA; Department of Biobehavioral Health, The Pennsylvania State University, University Park, PA, USA.

Parental permissiveness of drinking is a reliable predictor of college drinking, but there is little known about factors that predict such permissiveness. This study seeks to examine factors that predict two potentially different facets of permissiveness: perceived general approval of alcohol use and perceived drinking limits. Additionally, we explored how these facets mediate the relationship between the predictors of permissiveness and subsequent college drinking and related consequences.

Towards a 'people and nature' paradigm for biodiversity and infectious disease.

Philos Trans R Soc Lond B Biol Sci

January 2025

Centre for Biodiversity and Environment Research, Department of Genetics, Evolution and Environment,, University College London, London WC1E 6BT, UK.

Zoonotic and vector-borne infectious diseases are among the most direct human health consequences of biodiversity change. The COVID-19 pandemic increased health policymakers' attention on the links between ecological degradation and disease, and sparked discussions around nature-based interventions to mitigate zoonotic emergence and epidemics. Yet, although disease ecology provides an increasingly granular knowledge of wildlife disease in changing ecosystems, we still have a poor understanding of the net consequences for human disease.

Plant Cell Wall-Like Soft Materials: Micro- and Nanoengineering, Properties, and Applications.

Nanomicro Lett

January 2025

Department of Chemical Engineering, The Pennsylvania State University, University Park, PA, 16802, USA.

Plant cell wall (CW)-like soft materials, referred to as artificial CWs, are composites of assembled polymers containing micro-/nanoparticles or fibers/fibrils that are designed to mimic the composition, structure, and mechanics of plant CWs. CW-like materials have recently emerged to test hypotheses pertaining to the intricate structure-property relationships of native plant CWs or to fabricate functional materials. Here, research on plant CWs and CW-like materials is reviewed by distilling key studies on biomimetic composites primarily composed of plant polysaccharides, including cellulose, pectin, and hemicellulose, as well as organic polymers like lignin.

Widespread release of translational repression across Plasmodium's host-to-vector transmission event.

PLoS Pathog

January 2025

Department of Biochemistry and Molecular Biology, Pennsylvania State University, University Park, Pennsylvania, United States of America.

Malaria parasites must respond quickly to environmental changes, including during their transmission between mammalian and mosquito hosts. Therefore, female gametocytes proactively produce and translationally repress mRNAs that encode essential proteins that the zygote requires to establish a new infection. While the release of translational repression of individual mRNAs has been documented, the details of the global release of translational repression have not.

Hidden domain boundary dynamics toward crystalline perfection.

Proc Natl Acad Sci U S A

January 2025

Department of Materials Science and Engineering, Stanford University, Stanford, CA 94305.

A central paradigm of nonequilibrium physics concerns the dynamics of heterogeneity and disorder, impacting processes ranging from the behavior of glasses to the emergent functionality of active matter. Understanding these complex mesoscopic systems requires probing the microscopic trajectories associated with irreversible processes, the role of fluctuations and entropy growth, and the timescales on which nonequilibrium responses are ultimately maintained. Approaches that illuminate these processes in model systems may enable a more general understanding of other heterogeneous nonequilibrium phenomena, and potentially define ultimate speed and energy cost limits for information processing technologies.

The pulmonary route for drug administration has garnered a great deal of attention in therapeutics for treating respiratory disorders. It allows for the delivery of drugs directly to the lungs and, consequently, the maintenance of high concentrations at the action site and a reduction in systemic adverse effects compared to other routes, such as oral or intravenous. Nevertheless, the pulmonary administration of drugs is challenging, as the respiratory system tries to eliminate inhaled particles, being the main responsible mucociliary escalator.
