Valorization of bark extracts from Cerrado and Amazon species: phenolic characterization, antioxidant capacity, and photoprotective potential for circular bioeconomy applications

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Tree bark remains an underexploited source of high‐value‐added phenolic compounds with potential circular bioeconomy applications. This work characterized bark extracts from two species of distinct Brazilian biomes, Stryphnodendron adstringens (Cerrado) and Myrcia eximia (Amazon), obtained with three solvents (ethanol, methanol and acetone ...

Influence of Modeling Assumptions on the Inferred Dynamical State of Resonant Systems: A Case Study of the HD 45364 System

open access: yesThe Astrophysical Journal
Planetary systems exhibiting mean motion resonances (MMRs) offer unique opportunities to study the imprint of disk-induced migration on the orbital architectures of planetary systems. The HD 45364 system, discovered via the radial velocity (RV) method to

Mechanism study of an articular cartilage repair material and its forward‐looking test for space medicine

open access: yesBMEMat, EarlyView.
The regeneration process following dLhCG engraftment progressed through four distinct and interconnected stages. dLhCG maintained its regenerative efficacy after 6 months of cosmic exposure, supporting its potential application in space medicine.

Micro‐ and nanoplastics in gastrointestinal disorders: Mapping the translational gap between exposure, biomonitoring, and pathogenic mechanisms

open access: yesBMEMat, EarlyView.
This review highlights critical “translational gaps” in understanding micro‐ and nanoplastics impacts on gastrointestinal diseases, bridging exposure, detecting, and mechanistic toxicology. Abstract Micro‐ and nanoplastics (MNPs) have become pervasive environmental contaminants with increasing evidence linking them to adverse health outcomes.

Is Planetary Migration Inevitable?

open access: yes, 2006
International audienceAccording to current theories, tidal interactions between a disk and an embedded planet may lead to the rapid migration of the protoplanet on a timescale shorter than the disk lifetime or estimated planetary formation timescales ...

What drives animal responses to high severity fire? The role of functional traits

open access: yesBiological Reviews, EarlyView.
ABSTRACT Fire regimes are changing worldwide, with increases in the frequency, extent, and severity of fires posing growing risks to biodiversity. Fire severity – the degree of habitat alteration following fire – strongly influences both immediate survival and long‐term recovery of fauna.

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

open access: yesBiological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Exomoons of Circumbinary Planets

open access: yesThe Astrophysical Journal
Confirmation of the first exomoon remains elusive. Although several exomoon candidates exist around single stars, there are currently no candidates around circumbinary planets (CBPs).
