Alzheimer's &Dementia, Volume 22, Issue 5, May 2026.Abstract INTRODUCTION Circular RNAs (circRNAs) are emerging as key regulators of gene expression, synaptic plasticity, and neuronal function in Alzheimer's disease (AD). Here, we characterize the biological actions of circPDE4B, a highly expressed circRNA markedly reduced in AD. METHODS circPDE4B knockdown in neuronal progenitor cells was combined with

Field‐free programmable bipolar magnetic heterostructures for neuromorphic computing
InfoMat, Volume 8, Issue 5, May 2026.Neuromorphic computing mimics the brain's efficiency, yet typical memristors lack biological synapses' dual signal control. We introduce a magnetic memristor enabling bidirectional, multi‐state modulation without external fields, validated in image feature extraction and neural clustering.

Thermal Segregation and Reddening in Europa's Double Ridges
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Europa's double ridges often display lower albedo and redder color than their surroundings. Their unique topography may cause sublimation‐driven darkening due to illumination and self‐heating—the process of thermal segregation. We apply an advanced 3D thermophysical model, including shadowing and self‐heating through mutual exchange of ...

Will Galileo resolve the S-asteroid controversy? [PDF]
The longest running argument in asteroid science concerns mineral composition and meteoritic association of the asteroids assigned to taxonomic type S. The approaching flyby of the S-type asteroid Gaspra by the Galileo spacecraft will drag an even larger

Olivine Microstructure Constraints on Ureilite Parent Body Deformation
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Ureilites are ultramafic achondrites for which the parent body is unknown. Monomict ureilites, consisting primarily of olivine and pyroxene, are thought to represent mantle residues, carrying essential information for their parent body deformation history.

Archives of impact: The politics of craters on Earth
Geographical Research, Volume 64, Issue 2, May 2026.This paper examines Earth’s 195 confirmed impact craters as archives, exploring their cataloguing and presentation as heritage sites. It argues Western scientific framings using military language and emphasising catastrophe overlook settler colonialism’s violent histories and marginalise indigenous earth‐sky cosmologies.

The Steward Observatory asteroid relational database [PDF]
The Steward Observatory Asteroid Relational Database (SOARD) was created as a flexible tool for undertaking studies of asteroid populations and sub-populations, to probe the biases intrinsic to asteroid databases, to ascertain the completeness of data ...
