Five‐year change in brain metabolism across the spectrum of cognitive impairment in older adults: a quantitative MRI study

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION It is desirable to measure brain metabolism without needing ionizing radiation and elucidate its time trajectory. This study employed a positron emission tomography ‐validated, non‐invasive magnetic resonance imaging (MRI) technique to characterize longitudinal changes in cerebral metabolic rate of oxygen (CMRO2) in both ...

Formation and Characterization of Insoluble Anthocyanins‐λ‐carrageenan Biopolyelectrolyte Complexes: Structural Morphology, Thermal Stability, and Release Dynamics

open access: yesChemFoodChem, Volume 2, Issue 2, June 2026.
Insoluble biopolyelectrolyte complexes formed between blackberry anthocyanins and λ‐carrageenan are investigated. Optimal complexation occurs at low carrageenan ratios and acidic pH, producing porous hydrogel‐like structures with enhanced thermal stability.

Toward Carbon Neutrality: Pathways and Challenges in Green Steel Production

open access: yescScience, Volume 2, Issue 2, June 2026.
ABSTRACT Steel, a cornerstone of modern civilization and economic growth, has experienced exponential production growth, resulting in substantial carbon emissions owing to reliance on fossil‐based reducing agents and fuels. Although conventional steelmaking methods have improved, achieving the climate targets outlined in the Paris Agreement requires ...

Carbon Dioxide Uptake and Storage in Construction Materials: Mechanisms, Theoretical Capacity, and Global Potential

open access: yescScience, Volume 2, Issue 2, June 2026.
ABSTRACT The construction sector constitutes a major source of global carbon dioxide emissions, and cement production contributes substantially via fuel combustion and limestone decomposition. These challenges have encouraged the incorporation of carbon dioxide into construction materials through mineralization.

Climatic, lithologic and topographic control on alpine rock fracturing and talus evolution

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
Investigating Holocene rockwall–talus systems in an Alpine valley revealed that lithologic and topographic conditions in concert with climatic‐driven stresses and time since deglaciation result in rockwall fracture patterns that control rockfall size, erosion rates and the characteristics and evolution of talus.
