Probing Ultrafast Coherent Bandgap Modulation in Monolayer WSe2 by Nonlinear Optics

open access: yesAdvanced Optical Materials, Volume 14, Issue 5, 2 February 2026.
This work sheds light on how resonant nonlinear optics blursthe line between perturbative and non‐perturbative nonlinear optics. Measured deviationsfrom the quadratic second‐harmonic scaling near the excitonic resonance arisefrom optical Stark and Bloch‐Siegert shifts. The experimental results arefurther underpinned by analytical and numerical analysis

Nanoparticle Adjuvant Design Enhances Germinal Center Responses Targeting Conserved Subdominant Epitopes for Pan‐Coronavirus Vaccine Development

open access: yesAdvanced Science, Volume 13, Issue 7, 3 February 2026.
Current SARS‐CoV‐2 vaccines generate short‐lived, strain‐specific immunity. A polymeric TLR7 agonist nanoparticle (TLR7‐NP) adjuvant enhances lymph node targeting and promotes early and sustained germinal center responses toward conserved S2 epitopes of the spike protein.

Long‐term amyloid PET and MRI outcomes in a menopausal hormone therapy trial

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Associations of short‐term use of menopausal hormone therapy (mHT) with Alzheimer's disease (AD) and structural magnetic resonance imaging (MRI) biomarkers were investigated 10 years after an mHT trial. METHODS Recently menopausal women with good cardiovascular health were randomized to oral conjugated equine estrogens (oCEE) or ...

Sex‐specific acceleration of Alzheimer's pathogenesis by chronic sleep‐deprivation

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Sleep impairments likely contribute to Alzheimer's pathology, though specific contributions to disease progression are incompletely understood. We propose that autophagic impairment is associated with chronic sleep disruption and examine how sleep loss and stress influence disease development, including having impacts on ...

Alzheimer's clinical research data via R packages: The alzverse

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Sharing clinical research data is essential for advancing Alzheimer's disease (AD) research, yet challenges in accessibility, standardization, documentation, usability, and reproducibility persist. METHODS We developed R data packages to streamline access to curated datasets from key AD studies. A4LEARN includes data from the Anti‐
