Characterizing circadian rest–activity rhythm patterns across Alzheimer's disease continuum in Down syndrome

open access: yesAlzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract INTRODUCTION Sleep and circadian rest–activity rhythm (RAR) disruption may bidirectionally relate to Alzheimer's disease (AD). Down syndrome (DS), the most common genetic cause of AD, presents sleep disorders, yet RAR patterns across the DS‐associated AD continuum remain uncharacterized. METHODS We analyzed 7‐day wrist actigraphy in 140 adults

Assessing the Transferability of Species Distribution Models: A Cross‐Continental Evaluation

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
This study confirms that the conventional approach, namely using random holdout test datasets and the AUC, fails to reliably assess model transferability. Instead, using spatially independent test datasets and the RWIP provides a more robust evaluation approach.

Habitat Loss Shapes Isotopic Niche Responses of a Didelphid Opossum to Fragmentation in Neotropical Semideciduous Dry Forests of Central Brazil

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Stable isotope analysis indicates that fragmentation and habitat loss in semideciduous dry forests in the Brazilian Cerrado drive trophic niche shifts in Gracilinanus agilis, with potential consequences for its role as a seed disperser. ABSTRACT Habitat loss and fragmentation have notable effects on species' trophic ecology, often most pronounced in ...

Chemically‐Linked Heterostructures of Palladium Nanosheets and 2H‐MoS2

open access: yesSmall, Volume 22, Issue 25, 4 May 2026.
The photoresponse of MoS2 devices is extended to the near‐infrared region (up to 1700 nm) through chemical connection to Pd nanosheets (PdNS). A maleimide is used for covalent connection to MoS2, and a phenyl bromide moiety for linkage to the PdNS. In the absence of the chemical linker, van der Waals heterostructures show poorer enhancement of the ...

Suspendable and Scalable Ultrasound‐Actuated ZnO‐Nanosheet‐Based Piezoelectric Microdevices for Wireless Electrical Stimulation of Cells

open access: yesSmall, Volume 22, Issue 26, 8 May 2026.
Silicon microtechnology enables the scalable fabrication of cytocompatible microdevices for wireless electrical stimulation. Microdevices smaller than a cell allow accurate interaction with single cells. By integrating piezoelectric nanostructures that can be actuated by ultrasound within the biomedical range, remote electrical cell stimulation is ...
