Functional Polymer‐Engineered Magnetic Nanoparticles as Dual‐Modal Theragnostic Probes for Early Alzheimer's Disease Detection and Therapy

open access: yesAdvanced NanoBiomed Research, Volume 6, Issue 11, November 2026.
The nanoparticle consists of a 3 nm iron oxide core functionalized with an amphiphilic polymer coating containing Aβ‐targeting DSA moieties and biocompatible PEG chains. This design supports measurable transport in a BBB‐related model and specific interaction with Aβ species, while providing MRI contrast enhancement for diagnosis and therapeutic ...

Statistics of transition-region loop brightenings and their heating implication

open access: yesAstronomy & Astrophysics
Context. Transition-region loops are a type of critical magnetic structure in the solar atmosphere, yet their physical properties and evolutionary characteristics remain statistically poorly constrained. Aims.

Aerosol and cloud effects on solar brightening and the recent rapid warming

open access: yesGeophysical Research Letters, 2008
The rapid temperature increase of 1°C over mainland Europe since 1980 is considerably larger than the temperature rise expected from anthropogenic greenhouse gas increases.

pH‐Responsive Ultrasmall Iron Oxide Nanoassemblies for Activatable T2/T1 Magnetic Resonance Imaging

open access: yesAdvanced NanoBiomed Research, Volume 6, Issue 11, November 2026.
This research reports a pH‐responsive ultrasmall iron oxide nanoparticle (USIONs)/polymer nanoassemblies for activatable magnetic resonance imaging. Amphiphilic diphosphonic acid block copolymers compactly encapsulate USIONs to generate T2‐weighted contrast at physiological pH, while acidic conditions trigger disassembly, activating T1‐weighted ...

Southern Ocean Clear‐Sky Brightening From Sea Spray Aerosol Increase Drives Departure From Hemispheric Albedo Symmetry

open access: yesGeophysical Research Letters
Observations reveal significant negative trends in reflected shortwave radiation over the 21st century. The global‐mean darkening is primarily driven by clouds, while the global‐mean atmospheric clear‐sky signal is near zero due to offsetting trends in ...

Growth dynamics, skeletochronology, and histovariability of the theropod dinosaur Berthasaura leopoldinae

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3169-3186, November 2026.
Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...

Some Notes on La Faiseuse D'anges (A Fazedora De Anjos, 1908), by Pedro Weingärtner

open access: yesFuture Humanities, Volume 4, Issue 2, November 2026.
ABSTRACT Pedro Weingärtner's La Faiseuse d'Anges (A Fazedora de Anjos, 1908) stands as one of the most unsettling artefacts of Brazilian academic painting. Conceived in Rome but rooted in the Parisian fait divers of the ‘angel‐maker,’ it translates a sensational story of reproductive crime into a monumental moral tableau.

X-Currents and Extreme Brightening Events

open access: yes
The solar-terrestrial interaction is a dynamic process which manifests itself in the ionosphere. Interplanetary (IP) shocks or solar wind dynamic pressure pulses can generate enhanced brightening in dayside aurora.

The Contribution of Solar Brightening to the US Maize Yield Trend [PDF]

open access: yes, 2017
Predictions of crop yield under future climate change are predicated on historical yield trends1,2,3, hence it is important to identify the contributors to historical yield gains and their potential for continued increase.

Estimating the effects of aerosol, cloud, and water vapor on the recent brightening in India during the monsoon season

open access: yes, 2017
. India is experiencing a leveling-off trend of solar radiation, even a transition from dimming to brightening. This process is significantly complicated because of the active atmospheric action during monsoon season.
