Unlabelled: The Countdown is an international research collaboration that independently monitors the evolving impacts of climate change on health, and the emerging health opportunities of climate action. In its eighth iteration, this 2023 report draws on the expertise of 114 scientists and health practitioners from 52 research institutions and UN agencies worldwide to provide its most comprehensive assessment yet. In 2022, the Countdown warned that people’s health is at the mercy of fossil fuels and stressed the transformative opportunity of jointly tackling the concurrent climate change, energy, cost-of-living, and health crises for human health and wellbeing.

Breastfeeding and Postpartum Depression: A Review of Relationships and Potential Mechanisms.

Purpose Of Review: Postpartum depression (PPD) and breastfeeding are important, interrelated health factors. It is established that women who breastfeed exclusively have lowered likelihood of developing significant PPD. Yet, many questions remain around what factors are involved.

Efficient 2D to 0D Energy Transfer in HgTe Nanoplatelet-Quantum Dot Heterostructures through High-Speed Exciton Diffusion.

Large area absorbers with localized defect emission are of interest for energy concentration via the antenna effect. Transfer between 2D and 0D quantum-confined structures is advantageous as it affords maximal lateral area antennas with continuously tunable emission. We report the quantum efficiency of energy transfer in in situ grown HgTe nanoplatelet (NPL)/quantum dot (QD) heterostructures to be near unity (>85%), while energy transfer in separately synthesized and well separated solutions of HgTe NPLs to QDs only reaches 47 ± 11% at considerably higher QD concentrations.

Turning the Page on Breast Cancer in Ohio: Lessons learned from implementing a multilevel intervention to reduce breast cancer mortality among Black women.

Background: Turning the Page on Breast Cancer (TPBC) uses a multilevel approach to reduce breast cancer (BC) mortality among Black women. TPBC intervenes by (1) improving health care facilities' ability to conduct effective BC screening, follow-up, and treatment; (2) involving community-based organizations; and (3) providing education and personal risk information through a culturally relevant website. Ohio has among the worst BC mortality rates in the United States for Black women.

Phacofragmentation as an Effective Tool for Removal of Silicone Oil Adherent to Posterior Chamber Intraocular Lenses.

Background/purpose: To assess usefulness of phacofragmentation probe in the removal of silicone oil (SO) adherent to intraocular lenses (IOLs) during a SO removal procedure.

Methods: A 20-gauge (G) phacofragmentation probe was used to emulsify and remove SO adherent to IOLs during 23-G vitrectomy for SO removal. The superotemporal 23-G cannula was removed, and 20-G sclerotomy was made by using a 20-G MVR blade.

Human Subjects Research Guidelines for Undergraduate Researchers: An Analysis of Institutional Review Board (IRB) Websites at Top Liberal Arts Colleges in the United States.

Teaching students about the ethics of Human Subject Research (HSR) should be a fundamental component of students' education about research. In this article, we analyze the Institutional Review Board (IRB) websites of top-ranked Liberal Arts Colleges (LACs) to examine their framing of HSR carried out by undergraduate students. Our descriptive quantitative analysis from 50 top-ranked LACs in the United States indicates that a majority of IRB websites provide information about undergraduate research, and most include information about students' classroom-based research.

College transition Fall 2020 and 2021: Understanding the relationship of COVID-19 experiences and psychosocial correlates with anxiety and depression.

Rates of mental health symptoms, particularly anxiety and depression, have increased significantly in college students in the past decade along with utilization of mental health resources. The COVID-19 pandemic created an additional source of stressors to an already challenging landscape of college transition. COVID-19 has been associated with an increase of anxiety among college students, particularly first year students, entering college in Fall 2020.

Growth mindset of anxiety and avoidant coping as mediators of anxiety across the first year of college: A longitudinal survey of college students in the context of the COVID-19 pandemic.

Introduction: The purpose of this study was to evaluate the mediating role of growth mindset of anxiety beliefs and avoidant coping behaviors in predicting changes in anxiety across the first year of college, drawing from a sample of first year students managing the transition to college under the COVID-19 pandemic and associated restrictions (Fall 2020-Fall 2021).

Methods: Self-report online surveys (n=122) were administered to first year students at four timepoints: the beginning (August 2020; T1), and follow up surveys at two months (October 2020; T2), three months (November 2020; T3) and twelve months (August 2021; T4).

Results: Path analysis indicate that growth mindset of anxiety and avoidant coping partially mediate the relationship between baseline anxiety and later anxiety outcomes.

Rapid topographic growth of the Taiwan orogen since ~1.3-1.5 Ma.

We present the first paleotopographic reconstruction of Taiwan by measuring the hydrogen isotope composition of leaf waxes (δH) preserved in 3-Ma and younger sediments of the southern Coastal Range. Plant leaf waxes record the δH of precipitation during formation, which is related to elevation. Leaf waxes produced across the orogen are transported and deposited in adjacent sedimentary basins, providing deep-time records of the source elevation of detrital organic matter.

Insight into the Nucleotide Based Modulation of the Grp94 Molecular Chaperone Using Multiscale Dynamics.

Grp94, an ER-localized molecular chaperone, is required for the folding and activation of many membrane and secretory proteins. Client activation by Grp94 is mediated by nucleotide and conformational changes. In this work, we aim to understand how microscopic changes from nucleotide hydrolysis can potentiate large-scale conformational changes of Grp94.

The association between internet use to obtain health information and receiving three doses of the Hepatitis B vaccine in a multi-ethnic population in Ohio.

While most cancer incidence and mortality rates are decreasing, liver cancer rates are increasing. The Hepatitis B Virus (HBV) vaccine prevents liver cancer, although not everyone receives all three doses of the vaccine. This study examined the association between using the internet as the primary source of health information and receiving three HBV vaccine doses among a multi-ethnic population in Ohio.

Legacy effects in temporally separated tadpole species are not mediated by invasive Western Mosquitofish ().

Temporally separated species are often thought to have limited competition over a shared resource. However, early arriving species may consume a limited resource such that later-arriving species have access to fewer resources and thus experience competitive effects, even if they are temporally separated (i.e.

Niche conservatism and ecological change during the Late Devonian mass extinction.

Studies of the fossil record can inform our understanding of not only the causes of mass extinctions, but also their effects on biodiversity, ecology and evolution. Here, we examine regional-scale ecological changes resulting from a Late Devonian mass extinction event using brachiopod fossil assemblages from the Appalachian Basin. About half of the species went extinct, but were largely replaced by new immigrant taxa.

Allosteric communication in the gating mechanism for controlled protein degradation by the bacterial ClpP peptidase.

Proteolysis is essential for the control of metabolic pathways and the cell cycle. Bacterial caseinolytic proteases (Clp) use peptidase components, such as ClpP, to degrade defective substrate proteins and to regulate cellular levels of stress-response proteins. To ensure selective degradation, access to the proteolytic chamber of the double-ring ClpP tetradecamer is controlled by a critical gating mechanism of the two axial pores.

Psychosocial predictors of early postpartum depressive and anxious symptoms in primiparous women and their partners.

Background: While the majority of research on postpartum depressive and anxious symptoms has focused on mothers, a growing body of research suggests a need to understand the role of the partner's health and relationship quality as predictors of postpartum maternal depression, while also better understanding correlates of partner or paternal depression in the postpartum period. The purpose of the current study is to evaluate mother and partner stress, anxiety, mood, infant care support, and relationship quality as predictors of perinatal depressive and anxious symptoms in first time mothers and partners during the postpartum hospital stay.

Methods: First time parent couples (n = 116) completed a survey during the two-day postpartum stay in a Midwest hospital.

Maximizing light-driven CO and N fixation efficiency in quantum dot-bacteria hybrids.

Integrating light-harvesting materials with microbial biochemistry is a viable approach to produce chemicals with high efficiency from the air, water, and sunlight. Yet it remains unclear whether all absorbed photons in the materials can be transferred through the material-biology interface for solar-to-chemical production and whether the presence of materials beneficially affect the microbial metabolism. Here we report a microbe-semiconductor hybrid by interfacing CO/N-fixing bacterium with CdTe quantum dots for light-driven CO and N fixation with internal quantum efficiencies of 47.

Omit needless words: Sentence length perception.

Short sentences improve readability. Short sentences also promote social justice through accessibility and inclusiveness. Despite this, much remains unknown about sentence length perception-an important factor in producing readable writing.

Exploring the design of superradiant J-aggregates from amphiphilic monomer units.

Excitonic chromophore aggregates have wide-ranging applicability in fields such as imaging and energy harvesting; however their rational design requires adapting principles of self-assembly to the requirements of excited state coupling. Using the well-studied amphiphilic cyanine dye C8S3 as a template-known to assemble into tubular excitonic aggregates-we synthesize several redshifted variants and study their self-assembly and photophysics. The new pentamethine dyes retain their tubular self-assembly and demonstrate nearly identical bathochromic shifts and lineshapes well into near-infrared wavelengths.

Spectrally Selective Time-Resolved Emission through Fourier-Filtering (STEF).

We demonstrate a method for separating and resolving the dynamics of multiple emitters without the use of conventional filters. By directing the photon emission through a fixed path-length imbalanced Mach-Zehnder interferometer, we interferometrically cancel (or enhance) certain spectral signatures corresponding to one emissive species. Our approach, Spectrally selective Time-resolved Emission through Fourier-filtering (STEF), leverages the detection and subtraction of both outputs of a tuned Mach-Zehnder interferometer, which can be combined with time-correlated single photon counting (TCSPC) or confocal imaging to demix multiple emitter signatures.
