VLF Remote Sensing Across and Along the Totality Path During the 8 April 2024 Total Solar Eclipse Using a VLF Receiver Network

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.
Abstract During the total solar eclipse in the United States on 8 April 2024, we observed the amplitude and phase of Very Low Frequency (VLF) signals from five U.S. Navy VLF transmitters using a novel geometry of VLF receivers deployed along and across the totality path.

Maternal Immune Stimulation With Interferon‐Gamma Limits Embryonic Valproic Acid Induced Apoptotic Gene Expression

open access: yesBirth Defects Research, Volume 117, Issue 11, November 2025.
ABSTRACT Background Neural tube defects (NTDs) are developmental malformations affecting 1300 newborns in the United States each year. Valproic acid (VA), a drug to treat seizures and mood disorders, can cause NTDs. Apoptosis is increased in the developing neural tubes (NTs) of embryos exposed to VA thereby identifying a possible mechanism for NTD ...

Quantifying Cytotoxicity and Cellular Uptake of Naked Gold Nanoparticles Using Total Reflection X‐Ray Fluorescence

open access: yesX-Ray Spectrometry, Volume 54, Issue 6, Page 716-724, November/December 2025.
ABSTRACT The study of the cytotoxic effects of gold nanoparticles (AuNP) is an active area of research. However, there is a lack of consistency in results with measures of cellular uptake relying on inductively coupled plasma (ICP)‐based methods, which introduce inconsistencies with sample preparation.

Lighting the Way: Unveiling the Mechanisms of the Photoinduced Benzyl Alcohol Oxidation Using Tailored Bismuth‐Based Perovskite‐Inspired Microcrystals

open access: yesChemSusChem, Volume 18, Issue 20, October 23, 2025.
This work illustrates how the introduction of surface halide vacancies in heterogenous Cs3Bi2Br9 microparticles facilitates the aerobic conversion of benzyl alcohol into the corresponding aldehyde. The strategy demonstrates broader applicability outperforming the conventional methods and underscoring surface defect potential in sustainable ...

Current Practices for Analyzing Soils and Sediments via Mössbauer Spectroscopy

open access: yesJournal of Plant Nutrition and Soil Science, Volume 188, Issue 5, Page 742-773, October 2025.
ABSTRACT Environmental scientists are increasingly returning to Mössbauer spectroscopy (MBS) to reveal details about iron (Fe)‐bearing phases in soils and sediments. MBS is particularly powerful at distinguishing between Fe(II) and Fe(III) and, given appropriate background information, can offer exceptionally precise information on Fe speciation in ...

A tephrostratigraphic investigation of the continuously varved Holocene Boreal lake Nautajärvi, Finland, provides precise age estimate for Lairg A/Hekla 5 eruption

open access: yesJournal of Quaternary Science, Volume 40, Issue 7, Page 1212-1229, October 2025.
ABSTRACT Numerous cryptotephra layers originating from Icelandic volcanoes and further afield have reached Northern Europe during the Holocene. Refining the precise timing and the relative frequency of local and distal eruptions requires well‐resolved continuous sediment archives. Lake Nautajärvi is located in central‐southern Finland (61°48′ N, 24°41′
