Psychological Stress and the Diurnal Patterns of Sodium Excretion and Blood Pressure: Results From the SABRE Study

BACKGROUND: Psychological stress is associated with reduced blood pressure (BP) dipping, but the underlying mechanisms are unclear. This study examined the associations among stress-induced sodium excretion, diurnal sodium excretion, and BP dipping. METHODS: Apparently healthy ad...

Redox Buffering and Corrosion in Molten Chloride Salts Dictated by Chlorobasicity

Abstract This study establishes an in situ synchrotron approach to directly link molten-salt chemistry, redox-buffer speciation, and alloy corrosion in chloride melts. Using a first-of-its-kind corrosion cell coupled to simultaneous X-ray absorption spectroscopy (XAS) and X-ray f...

pynucastro 3: A community library for nuclear astrophysics

We describe the latest release of pynucastro: a community python library for nuclear astrophysics. The goal of the pynucastro project is to build the tools needed to interactively explore nuclear properties, reaction rates, and networks, and to export these networks to a variety...

Cytoplasmic C-Terminal Domain of the MmpL11 Lipid Transporter Is Required for Interaction with Its Co-cistronic Partner MSMEG_0240 in Mycobacterium smegmatis

Abstract MmpL proteins play an important role in the various mechanisms associated with mycobacterial virulence. Identification of interacting protein partners by classical in vitro methods is hampered by the low solubility of these integral membrane proteins. In this study, we u...

MOF-Supported Pt-Alloy Electrocatalysts for Oxygen Reduction Reaction in PEM Fuel Cells: Design, Performance, and Future Directions

Abstract Proton exchange membrane fuel cells (PEMFCs) are promising energy conversion technologies for transportation, portable power, and stationary energy applications because of their high efficiency and low emissions. However, the widespread commercialization of PEMFCs remain...

Airflows redefine the cost of aerial transport in the wild

Fuel economy matters to both animals and machines, as the cost of transport can determine where, when, and how far locomotion is possible. However, established estimates of these values for animal flight come from laboratories and treat the atmosphere as constant, even though fre...

Sub‐Seasonal Forecasting of Precipitation and Soil Moisture in CFSv2 Near Gulf Coast Tropical Cyclone Landfall Locations

Abstract Landfalling tropical cyclones (TCs) produce intense winds, heavy precipitation, and damaging storm surges along the Gulf and East coast of the U.S. There is growing evidence that high antecedent soil moisture (SM) conditions preceding landfall can maintain or even intens...

Broadband Near-Field Imaging of Strong Polariton Coupling in Graphene/CrI3 Heterostructures

Abstract Interfacial charge transfer in van der Waals heterostructures provides a powerful, contact-free mechanism to activate two-dimensional plasmons. Chromium iodide (CrI3), a layered ferromagnetic insulator, induces significant doping in adjacent graphene, yet its nanoscale p...

Formation of Calcium Carbonate under Permanent Magnetic Fields: Insights from X-Ray Scattering and Molecular Dynamics Simulations

Abstract Electromagnetic treatment has been used in water desalination to control mineral scale formation and maximize membrane performance. However, the mechanism(s) by which external fields influence mineral scale formation remain poorly understood. This study used X-ray scatte...

Gauss law constraint in A-theory branes

{\cal A} -theory realizes U-duality symmetry by extending the string worldsheet to a higher dimensional brane worldvolume, in which the worldvolume and the spacetime belong to different representations of the exceptional group. The closure of the brane Virasoro algebra requires t...

Exploring transcriptomic and genomic latent variable correction approaches in differential expression analysis

Abstract Background Differential expression analysis is a central tool for studying the biological processes altered in human diseases via transcriptomic signatures. However, transcriptomic datasets are systematically confounded by latent variables from two distinct sources: unme...

Unearthing Toxic Beauty: Project CLEAR Protocol to Assess Skin-Lightening Product Exposure in Northern Manhattan

Skin lightening products (SLPs) are widely used among communities of color and often contain toxic chemicals that pose serious health risks. Despite regulations, these products remain accessible in the United States through deceptive labeling and illegal sales, which might contri...

Biochar amendments in a California salt marsh restoration reduced denitrification and supported distinct microbial community functions

Accelerated sea level rise, combined with human-induced changes to hydrology and sediment transport, threatens the long-term persistence of coastal wetlands. Sediment addition is increasingly used to enhance wetland resilience to sea level rise, and incorporating biochar, a carbo...

Carbonic Acid (H2CO3) Decomposes to Its Monohydrate (H2CO3·H2O) and CO2 on Decompression

Abstract The presence of H2O and CO2 on the icy moons in our solar system and in potentially habitable water worlds makes the understanding of phase stabilities and structure–property relations of phases in the H2O–CO2 system highly relevant for astrophysical research. Here we sh...

Structural and Rheological Signatures of the Salt-in-Solvent to Solvent-in-Salt Transition in a Fluorinated Ester Electrolyte

Abstract Experimental measurements and molecular dynamics (MD) simulations study the structural and rheological properties of a model fluorinated ester electrolyte, methyl 3,3,3-trifluoropropionate (MTFP) with LiFSI, over a wide concentration range (0.1–2.3 mol/kg). MD simulation...

Per- and Polyfluoroalkyl Substances (PFAS) Cytotoxicity and Genotoxicity in HepG2 Human Hepatoma Cells

Abstract Per- and polyfluoroalkyl substances (PFASs) commonly occur as complex mixtures, yet the relationships among PFAS structure, cytotoxicity, and DNA strand-break responses remain incompletely resolved. We evaluated 11 PFASs selected to span environmentally prevalent and reg...

Protein secretion by the type IV pilus machinery in Francisella tularensis

ABSTRACT Francisella tularensis is a highly virulent, Gram-negative bacterial pathogen that causes the zoonotic disease tularemia. F. tularensis infects a variety of host cells and replicates intracellularly while evading and interfering with host immune responses. The molecular...

Developmental trajectories of tonic and phasic irritability from ages 12 to 21: early predictors, co‐development, and psychiatric outcomes in young adulthood

Background Irritability is a common and impairing, transdiagnostic feature of youth psychopathology. Theory distinguishes tonic irritability (persistent irritable mood) from phasic irritability (episodic temper outbursts), yet little is known about how these dimensions co‐develop...

Structural stigma and LGBTQ+ youth mental health in the United States

Structural stigma, or systemic barriers to equity for minoritized populations, has been shown to have negative consequences on LGBTQ+ youth’s mental health. Most research has focused on stigma at the national or state level, limiting understanding of how local institutions and en...

Scalable, Simple, and Versatile Encapsulation of 2D Materials and Devices

Abstract Air-sensitive 2D materials present fundamental challenges for device integration. Encapsulation is required to preserve intrinsic properties, yet conventional strategies require complicated fabrication workflows and fail with thicker flakes. We demonstrate that electron-...
