Generational effects in Down syndrome: Enriched environment enhances functionality without reducing Alzheimer's disease risk

open access: yesAlzheimer's &Dementia, Volume 21, Issue 10, October 2025.
Abstract INTRODUCTION Down syndrome (DS) is the leading cause of intellectual disability (ID) and a genetic form of Alzheimer's disease (AD). We wanted to assess whether generational changes have induced (1) milder ID with greater independence and (2) delayed AD diagnosis.

Recent Trends in Conjugated Polymer‐Based Thermoelectrics From Materials to Device

open access: yesEcoMat, Volume 7, Issue 10, October 2025.
Conjugated polymers (CPs) have shown dramatic advances in their thermoelectric (TE) power factor over the past decades, enabling biocompatible, solution‐processable, lightweight, and deformable (flexible/stretchable) TE generators. Material engineering principles have played an essential role in the remarkable improvements in power factor, including ...
