Inflammation Associated With Obesity, Aging, and Amyloid Burden in Adults With Down Syndrome

open access: yesObesity, Volume 34, Issue 7, Page 1457-1467, July 2026.
ABSTRACT Objective Adults with Down syndrome (DS) often show elevated systemic inflammation, but the association with obesity, aging, and Alzheimer's disease (AD) pathology is not well understood. Methods Data were drawn from 188 nondemented adults with DS participating in the Alzheimer Biomarkers Consortium‐DS (ABC‐DS). Participants completed clinical

Efficient and Durable Semitransparent Perovskite Solar Cells for the Application in 4T Perovskite/c‐Si Tandem Devices

open access: yesProgress in Photovoltaics: Research and Applications, Volume 34, Issue 7, Page 887-905, July 2026.
We present an optimized fabrication strategy incorporating a solution‐processed SnO2 buffer layer that prevents sputter‐induced damage during TCO deposition, enabling semitransparent perovskite solar cells with 21.87% efficiency, 27.15% in tandem, and exceptional long‐term stability under continuous illumination and outdoor conditions.

Finding Fireballs in Lightning: A Daily Pipeline to Find Meteors in Weather Satellite Data

open access: yesEarth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Weather satellite data contains a wealth of information well beyond its application to meteorology. The GOES weather satellite Geostationary Lightning Mapper instruments detect millions of lightning strikes per day. Within these “haystacks” of lightning are a handful of “needles” of bolides (aka bright fireballs, or exploding meteors). We have

In Situ Regenerative Adduct Assisted p‐Type Doping of Organic Semiconductor

open access: yesAdvanced Materials, Volume 38, Issue 34, 17 June 2026.
An in situ regenerative adduct‐assisted (IRAA) doping strategy is introduced for p‐type doping of organic semiconductors. A regenerating adduct serves as the dopant, enabling highly efficient doping with a choice of counterions. The generality of this approach provides a scalable route to dope a wide range of hole‐transport materials with high thermal ...

Nature's Nanotech Warriors: The Role of Metalloproteins and Protein Cages for Environmental Remediation

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 6, June 2026.
Cartoon representation of five major classes of metalloproteins and their brief mechanisms of bioremediation. The five classes include metallothioneins, metal‐precipitating enzymes, P.‐type ATPases, protein cages, and synthetic metalloproteins (de novo‐designed proteins/peptides for selective adsorption). These natural and engineered protein structures

Sex differences in brain glucose metabolism and Alzheimer's disease risk and progression

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract Sex differences are increasingly recognized as central to the biology of Alzheimer's disease (AD), yet the mechanisms through which they shape brain metabolism and disease vulnerability remain incompletely understood. Brain glucose hypometabolism is a core hallmark of AD and emerges decades before clinical decline, but accumulating evidence ...

Intraindividual cognitive variability predicts amyloid beta, tau PET, and dementia conversion in Down syndrome: a potential marker of cognitive resilience

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION Adults with Down syndrome (DS) are at risk for Alzheimer's disease (AD), yet identifying the preclinical phase remains challenging. Intraindividual cognitive variability (IICV) may be a sensitive marker of early AD‐related changes but remains understudied in DS.

La apertura comercial y el proceso de convergencia departamental en Colombia: 2000-2016

open access: yes, 2018
El crecimiento económico regional en Colombia ha sido desequilibrado con el trascurso del tiempo, lo que provoca grandes brechas en el desempeño económico departamental y, por tanto, que no haya bienestar social.
