Frequency‐Dependent Seismic Velocity Variations Reveal Layered Aquifer Behavior Under Groundwater Fluctuations

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Frequency‐dependent seismic velocity variations (dv/v) provide depth‐resolved constraints on aquifer behavior under groundwater fluctuations. We analyze 17 years of dv/v time series from ambient noise interferometry in the Chiang Mai Basin, Thailand, and observe contrasting dv/v behavior below and above 1 Hz. By integrating GPS, meteorological,

Sound Velocities of FeO‐Bearing Ringwoodite and Majorite: Implication for Martian Mantle Seismic Profiles

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Compressional and shear wave velocities (Vp, Vs) of candidate Martian deep‐mantle minerals, FeO‐rich ringwoodite ((Mg0.66Fe0.34)2SiO4) and majorite (Mg0.75Fe0.10Al0.26Ca0.07Si0.84O3), were measured up to 25 GPa and 700 K using Brillouin light scattering coupled with externally‐heated diamond anvil cells.

Persisting Modulation of Interdecadal Pacific Oscillation on Near‐Future Winter Precipitation Projections in Northern Europe

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract European winter precipitation profoundly influences regional hydroclimate, yet the relative roles of internal variability and external forcing in its decadal changes remain elusive. Using large‐ensemble climate simulations, we identify the Interdecadal Pacific Oscillation (IPO) as a potential driver of interdecadal changes in winter northern ...

Global ethnic disparities in cerebral small vessel disease imaging markers and vascular risk factors: a systematic review and meta‐analysis

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract Ethnic disparities in cerebral small vessel disease (CSVD) have been reported, but no systematic synthesis has compared markers and vascular risk factors across populations. We conducted a PROSPERO‐registered systematic review and meta‐analysis (CRD42024518105) including over two million community‐dwelling adults.

Plasma and neuroimaging biomarkers of small vessel disease and Alzheimer's disease in a diverse cohort: MESA

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Little is known about how Alzheimer's disease (AD) plasma biomarkers relate to cerebral small vessel disease (cSVD) neuroimaging biomarkers. METHODS The study involved 251 Wake Forest Multi‐Ethnic Study of Atherosclerosis (MESA) Exam 6 participants with plasma AD biomarkers, magnetic resonance imaging, amyloid positron emission ...

Female‐biased astrocytic priming shapes early locus coeruleus vulnerability in an Aβ oligomer milieu

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION The locus coeruleus (LC) is an early site of Alzheimer's disease (AD) pathology, yet the role of brainstem astrocytes in early, sex‐dependent vulnerability remains unclear. METHODS In 2‐ to 3‐month‐old APP/PS1 mice, we combined in vivo proton magnetic resonance spectroscopy (MRS) of the brainstem with region‐resolved molecular ...

Falls predict faster progression to Alzheimer's dementia

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION In preclinical Alzheimer's disease (AD), amyloid accumulates in the brain while individuals remain cognitively unimpaired (Clinical Dementia Rating® [CDR] = 0). Differentiating trajectories of healthy aging and preclinical AD is challenging as both are associated with age‐related impairments (e.g., falls).

Protective Effects of Myrtus communis Essential Oil Against Bisphenol A‐Induced Metabolic Dysfunction‐Associated Fatty Liver Disease in Wistar Rats

open access: yesFood Science &Nutrition, Volume 14, Issue 2, February 2026.
Exposure to bisphenol A (BPA) induced hepatic steatosis associated with metabolic dysfunction (MASLD) in Wistar rats, characterized by dyslipidemia, oxidative stress, and hepatic steatosis. Co‐treatment with essential oil of myrtus communis (EOMC) improved markers of liver function, lipid profile, and antioxidant status, with histological improvement ...
