Tracking early cognitive decline in preclinical AD with brain MRI similarity

Alzheimer's &Dementia, Volume 22, Issue 3, March 2026.
Abstract INTRODUCTION Early detection of neuroanatomical changes in preclinical Alzheimer's disease (AD) is critical for timely intervention. However, conventional magnetic resonance imaging (MRI) and fluid biomarkers often lack sensitivity to subtle structural alterations in early disease stages. METHODS To identify early brain alterations, we applied

Tau PET overlap index correlation with neuropathological findings

Alzheimer's &Dementia, Volume 22, Issue 3, March 2026.
Abstract INTRODUCTION The tau positron emission tomography (PET) overlap index (OI) has shown promise in maximizing signal‐to‐noise for longitudinal tau PET imaging, particularly for early tau pathology, but requires validation against neuropathology.

Mixed Conversion‐Alloying Chemistry of Sn4P3 Anodes in Alkali‐Ion Batteries: Mechanistic Insights, Challenges, and Mitigation Strategies

ChemistryEurope, Volume 4, Issue 3, March 2026.
Sn4P3 offers high capacity via mixed conversion‐alloying chemistry in Li/Na/K systems but suffers from irreversible capacity loss, volume change, low initial cycle Coulombic efficiency, and interphase instability. This concept article evaluates the recent advances and charts routes to durable, practical Sn4P3 electrodes.

Early Cancer Detection: What's Going on and What's Next

MedComm, Volume 7, Issue 3, March 2026.
Multicancer early detection (MCED) platforms have emerged as a promising strategy for the safe and effective early detection of multiple cancer types, with the potential to reduce metastatic burden and improve clinical outcomes, particularly for aggressive malignancies that lack effective population‐level screening.

Redox Reaction and Dissolution Analysis for Hollow C Nanospheres Comprising N‐Doped C Framework With Abundant Ni–Co Heteronuclear Catalysts for Highly Durable K‒Te Batteries

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Tellurium (Te), emerging as a promising alternative to sulfur (S) and selenium (Se), offers significant advantages for potassium (K) ion storage due to its comparable theoretical volumetric capacity (2619 mAh cm−3) and higher electronic conductivity (∼102 S m−1), which promotes rapid charge transfer and improves reaction kinetics.

L'interprétation géopolitique du PIB

, 2021
Le Produit Intérieur Brut (PIB) est souvent un indicateur important dans la comparaison de la puissance comparée des Etats. Cependant, cette interprétation n’est pas toujours pertinente, notamment du fait des difficultés techniques portant sur les comparaisons intertemporelles et internationales des pays concernés, mais aussi d’autres facteurs qui ne ...

Design and Performance of Two‐Sided Self‐Protecting Perovskite Solar Cells for Indoor Vertical Applications

Small Science, Volume 6, Issue 3, March 2026.
Two‐sided self‐protecting perovskite solar cell scheme in a working ambient, doubling performances and extending stability over time with respect to the reference perovskite solar cell. We present a novel photovoltaic architecture that integrates two perovskite solar cells (PSCs), each fabricated on a separate substrate and bonded back‐to‐back, forming
