Membrane Complexity and Phase Behavior Dictate the Stability of Membrane‐Inserted Aβ42 Hexamers

ChemPhysChem, Volume 27, Issue 16, 27 August 2026.
Neuronal membrane order and the specific interplay of constituent lipids modulate the structural stability of Aβ(1–42) hexamers. This lipid environment facilitates the stabilization of a transmembrane β‐barrel conformation, providing a molecular basis for understanding how membrane composition influences the formation of stable amyloid pores in ...

3D Bioprinted Breast Cancer‐Stroma Model with Tailored Migration‐Permissive Bioink Reveals Impact of Adipose‐Derived Stromal Cells on Cancer Cell Migration and Invasion Dynamics

Advanced Healthcare Materials, Volume 15, Issue 30, 14 August 2026.
A migration‐permissive bioink composed of methacrylated collagen type I and thiolated hyaluronic acid enables 3D bioprinting of breast cancer‐stroma models. Single‐cell tracking reveals that adipose stromal cells enhance tumor cell motility and stromal invasion, accompanied by collagen remodeling, and a shift in tumor cell morphology.

Making Sense of the Bioeconomy: A Critical Analysis of EU Policy Narratives and Responses

Environmental Policy and Governance, Volume 36, Issue 4, Page 1049-1064, August 2026.
ABSTRACT The bioeconomy has become an increasingly popular concept in European Union (EU) policy, promising sustainable growth, job creation, and reduced environmental impacts. Yet its meaning remains contested, ambiguous, and politically charged. This study critically examines how EU bioeconomy policy narratives prior to 2025 construct this concept ...

Race‐Based Rejection Sensitivity and Intergroup Anxiety Across the Adult Lifespan: Examining Age, Cohort, and Period Effects Among Ethnic Majority and Minority Groups

European Journal of Social Psychology, Volume 56, Issue 5, Page 939-958, August 2026.
ABSTRACT Intergroup interactions are often fraught with fear of rejection and intergroup anxiety—emotional reactions that undermine efforts to build inclusive societies. The current research investigates how race‐based rejection sensitivity and intergroup anxiety evolve across the adult lifespan.

Calibration of Retrospective and Prospective Life Satisfaction Judgments Around the World

FUTURES &FORESIGHT SCIENCE, Volume 8, Issue 2, August 2026.
ABSTRACT It is both a physical and psychological fact that humans have access to records of the past but not to records of the future. Due to this epistemic asymmetry in time, we hypothesized that retrospection about past psychological states will be better calibrated than prospection about future psychological states.

Buffering Effects of Physical Activity on Negative Life Events–Life Satisfaction Dynamics

Stress and Health, Volume 42, Issue 4, August 2026.
ABSTRACT This study investigated whether physical activity buffers the association between negative life events and life satisfaction, distinguishing between dependent (e.g., divorce) and independent (e.g., bereavement) stressors as well as within‐ and between‐person processes across one‐ and 2‐year intervals (indicating short‐ and medium‐term ...

Currents in the Martian Ionosphere: Cases Without Strong Crustal Magnetic Fields

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract The Martian ionosphere hosts complex current systems driven both by solar wind interactions and neutral wind dynamo processes. While the global patterns of these current systems have been statistically examined, their detailed structures and orientations remain poorly constrained.

Quantifying Cortical Maturational Aspects During Different Vigilance States in Preterm Infants by Advanced EEG Analysis

Journal of Sleep Research, Volume 35, Issue 4, August 2026.
ABSTRACT Preterm birth is a significant risk factor for atypical neurodevelopment, yet early electrophysiological markers of brain maturation are still lacking. Non‐invasive electroencephalographic (EEG) monitoring of cortical maturation in these patients holds promise as a tool for neurodevelopmental prediction.
