The Gendered Consequences of a Weak Infrastructure of Care: School Reopening Plans and Parents’ Employment During the COVID-19 Pandemic
This article collected detailed primary data—the Elementary School Operating Status database (ESOS)—to measure the percentage of school districts offering in-person, remote, and hybrid instruction models for elementary schools by state in September 2020 to understand the nature and magnitude of school closures across states during the COVID-19 pandemic and its effect on maternal labor force participation. The article shows that schools are a vital source of care for young children, and that without in-person instruction, mothers have been sidelined from the labor force.

Gene-based association tests using GWAS summary statistics and incorporating eQTL
Article proposes a powerful and computationally efficient gene-based association test, called Overall. Using extended Simes procedure, Overall aggregates information from three types of traditional gene-based association tests and also incorporates expression quantitative trait locus (eQTL) information into a gene-based association test using GWAS summary statistics. The results show that this newly developed method can identify more significant genes than other methods.

Genetic Differentiation of the South Florida Red-Shouldered Hawk (Buteo lineatus extimus) from the Nominate Subspecies (Buteo lineatus lineatus)
Article discusses how the south Florida subspecies of the Red-shouldered Hawk (Buteo lineatus extimus) is distinctly paler and smaller than other subspecies, reproduces at a lower rate, and can occupy very different habitats such as open marshes and grasslands with only scattered trees. The authors evaluated population differentiation between the south Florida population of Red-shouldered Hawks and two populations of eastern Red-shouldered Hawks (B. l. lineatus) in suburban (Cincinnati) and rural (Hocking Hills) environments in southern Ohio.

Green synthesis of olefin-linked covalent organic frameworks for hydrogen fuel cell applications
This article creates a green strategy to fabricate a highly crystalline olefin-linked pyrazine-based covalent organic framework (COF) with high robustness and porosity under solvent-free conditions. This study opens up new possibilities for the green synthesis of advanced materials and provides important guidance for the rational design and synthesis of polymeric materials for proton-exchange membrane fuel cell applications.

A Highly Contiguous and Annotated Genome Assembly of the Lesser Prairie-Chicken (Tympanuchus pallidicinctus)
Article asserts that the Lesser Prairie-Chicken (Tympanuchus pallidicinctus; LEPC) is an iconic North American prairie grouse, renowned for ornate and spectacular breeding season displays, a species that has been declining in population across much of its historical range, with corresponding precipitous declines in contemporary population abundance, largely due to climatic and anthropogenic factors. The authors describe an annotated reference genome that was generated from a LEPC sample collected from the southern DPS.

Infrared radiative switching with thermally and electrically tunable transition metal oxides-based plasmonic grating
Article says that plasmonic and phase transition has been blended to gain the infrared radiative switching which is tunable with temperature or voltage supply. This is applied via vanadium dioxide, tungsten trioxide, and molybdenum trioxide as transition metal oxides (TMO), the authors state that the work expands the usage of transition metal oxides in infrared region with larger contrast.

Laser powder bed fusion processing of a precipitation strengthenable FCC based high entropy alloy
Article describes how, while additive manufacturing (AM) of single-phase solid solution based high entropy alloys (HEAs) has attracted a lot of recent attention, such processing of precipitation strengthenable multi-phase HEAs has not been actively investigated. This becomes important since AM processing results in each layer experiencing rapid solidification followed by multiple heating-cooling cycles, mimicking in situ heat treatments, potentially influencing the phase evolution.
