Multi-scale biodiversity drives temporal variability in macrosystems
Article using decadal datasets that span aquatic and terrestrial macrosystems and structural equation modeling to show that local temporal variability and spatial synchrony increase temporal variability for entire macrosystems. This analysis is among the first to provide a quantitative argument for the value of regional species diversity.

Development of a Thulium Fiber Laser for an Atomic Spectroscopy Experiment
This article is a simplified analysis of a convenient thulium fiber laser source with 3 W of output power operating at a wavelength of 2059 nm with a slope efficiency of 49% with respect to input pump power and 60% with respect to absorbed pump power. The laser was applied in an atomic helium spectroscopy experiment to quench ³He (2058.63 nm) and ⁴He (2058.69 nm) meta-stable singlets (2¹S0), allowing for further investigation of the helium fine structure.

In vivo Evaluation of Non-viral NICD Plasmid-Loaded PLGA Nanoparticles in Developing Zebrafish to Improve Cardiac Functions
This article presents a study with the purpose to deliver a Notch Intracellular Domain (NICD)-encoded plasmid via poly(lactic-co-glycolic acid) (PLGA) nanoparticles and to investigate the toxic environmental side effects for an in vivo experiment. This research demonstrates that PLGA nanoparticle-mediated target delivery to upregulate Notch related genes can be a potential therapeutic approach with minimum toxic effects.

Cardiac and metabolic physiology of early larval zebrafish (Danio rerio) reflects parental swimming stamina
This article explores swimming stamina in fish. Mature adult zebrafish (Danio rerio) were subjected to a swimming performance test and then bred within performance groups to discover if enhanced swimming stamina in offspring appears only in juveniles/adults, or if these traits appear as early as larvae.

Dissecting the transcriptional regulation of proanthocyanidin and anthocyanin biosynthesis in soybean (Glycine max)
This article analyzes the transcriptional control of PA and anthocyanin biosynthesis in soybean. Results show that engineered PA biosynthesis in soybean exhibits qualitative and spatial differences from the better-studied model systems Arabidopsis thaliana and Medicago truncatula, and suggest targets for engineering PAs in soybean plants.

Dementia and COVID-19 among Older African American Adults: A Scoping Review of Healthcare Access and Resources
Article discusses how African American/Black communities comprise 12.2% of the U.S. population, with a COVID-19 infection rate of more than 18% and marginal access to healthcare services. This scoping review synthesizes the emerging evidence on healthcare accessibility among older African American adult communities with dementia and COVID-19, as well as the resource requirements for this population during the pandemic.

Linking random forest and auxiliary factors for extracting the major economic forests in the mountainous areas of southwestern Yunnan Province, China
Article describes how forests are generally extracted from remotely sensed images based on the spectral features, ignoring other important auxiliary information, and the techniques of precise extraction need to be further improved. By using the Sentinel–2 image and auxiliary factors (AFs) including site conditions (SCs) and vegetation indices (VIs), the random forest model with AFs (RF–AFs) was adopted for the extraction of the economic forests in Lancang County.

Tuning excited state electronic structure and charge transport in covalent organic frameworks for enhanced photocatalytic performance
Article describes how covalent organic frameworks (COFs) represent an emerging class of organic photocatalysts. The authors use reticular chemistry to construct a family of isoreticular crystalline hydrazide-based COF photocatalysts, with the optoelectronic properties and local pore characteristics of the COFs modulated using different linkers.

A theoretical study of M–M′ polar-covalent bonding in heterobimetallic multinuclear organometallic complexes of monovalent group 11 metal centres
Article describes how complexes with closed-shell (d10–d10) interactions have been studied for their interesting luminescence properties in organic light-emitting diode (OLED) devices. The present computational study aims at understanding the chemical bonding/interactions in a series of molecules with unusually short metal–metal bond distances between monovalent coinage-metal (d10–d10) centres.

Disentangling Orbital and Valley Hall Effects in Bilayers of Transition Metal Dichalcogenides
This article shows that a bilayer of 2H-MoS₂ is an orbital Hall insulator that exhibits a sizeable orbital Hall effect in the absence of both spin and valley Hall effects. The results are based on density functional theory and low-energy effective model calculations and strongly suggest that bilayers of TMDs are highly suitable platforms for direct observation of the orbital Hall insulating phase in two-dimensional materials.

Spatially confined protein assembly in hierarchical mesoporous metal-organic framework
Article discusses how the immobilization of biomolecules into porous materials could lead to significantly enhanced performance in terms of stability towards harsh reaction conditions and easier separation for their reuse. To gain insights into the spatial arrangement of biomolecules within the nanopores, the authors used in situ small-angle neutron scattering (SANS) to probe deuterated green fluorescent protein (d-GFP) entrapped in a mesoporous MOF.

Automated Approach to In Vitro Image-Guided Photothermal Therapy with Top-Down and Bottom-Up-Synthesized Graphene Quantum Dots
Article discusses how, based on recent studies, graphene quantum dots (GQDs) are expected to possess advantageous photothermal properties and facilitate fluorescence image-tracking in the visible and near-infrared (NIR), while surpassing other graphene-based materials in their biocompatibility. The combination of the photothermal and imaging modalities tested in vitro makes the GQDs developed in this work prospective agents for cancer theragnostics.
