Plasticity in climate change responses

Biological Reviews, Volume 100, Issue 6, Page 2508-2527, December 2025.
ABSTRACT Recent research has shown that climate change can both induce and modulate the expression of plastic traits but our understanding of the role of phenotypic plasticity as an adaptive response to climate change is limited. In this review, we dissect the mechanisms and impact of phenotypic plasticity as a response to accumulating climatic ...

Topological Vortex Transition Induced by Spin Hall Effect of Light for Tunable Humidity Sensing and Imaging

Laser &Photonics Reviews, Volume 19, Issue 21, November 6, 2025.
This study introduces a humidity‐responsive optical imaging technique capable of dynamically switching between edge detection and bright‐field imaging modes. Utilizing humidity‐induced modulation of refractive index and polarization‐dependent beam shaping, tunable optical imaging is achieved through controlled beam splitting governed by the spin Hall ...

Comprehensive Molecular Modeling Analysis of Betulin, a Triterpene Isolated from Miconia burchellii (Melastomataceae) Native to the Brazilian Cerrado

ChemistrySelect, Volume 10, Issue 40, October 27, 2025.
Betulin, isolated from the Brazilian Cerrado plant Miconia burchellii, was comprehensively characterized using X‐ray diffraction, DFT, and molecular modeling. Solid‐state analysis revealed stabilizing O···H and H···H contacts, while DFT calculations (HOMO–LUMO gap: 9.38 eV) indicated moderate stability.

Efficient depletion of ribosomal RNA for RNA sequencing in planarians

BMC Genomics, 2019
Background The astounding regenerative abilities of planarian flatworms prompt steadily growing interest in examining their molecular foundation. Planarian regeneration was found to require hundreds of genes and is hence a complex process.

Ageing versus developmental silencing: Answers from the epigenome

The FEBS Journal, Volume 292, Issue 20, Page 5324-5330, October 2025.
It is easier for young animals to regenerate damaged or missing tissues. In this Viewpoint, we propose that this is, in part, attributed to epigenetic changes, with chromatin becoming more closed and inaccessible as animals age. The timing of when this occurs differs depending on the tissue—some during the late developmental stages and others at the ...

A planarian nidovirus expands the limits of RNA genome size

bioRxiv, 2018
RNA viruses are the only known RNA-protein (RNP) entities capable of autonomous replication (albeit within a permissive environment). A 33.5-kb nidovirus has been considered close to the upper size limit for such entities; conversely, the minimal ...

Biofouling reduction by lantern nets exchange and its relationship with production and survival of Argopecten purpuratus in Samanco Bay, Peru

Journal of the World Aquaculture Society, Volume 56, Issue 5, October 2025.
Abstract The aquaculture of Argopecten purpuratus (Peruvian scallop) is a profitable activity with positive impacts on the local economy. However, the development of biofouling on the culture lantern nets generates negative environmental impacts that affect its sustainability.

Whole‐Gut Spatial Genomic Analysis Reveals Molecular Regionalization of the Differentiating Zebrafish Enteric Nervous System

The FASEB Journal, Volume 39, Issue 17, 15 September 2025.
Spatial genomic analysis of the developing enteric nervous system in zebrafish through multiplex whole mount HCR in slide identified genes that have temporal and spatial expression patterns during development. ABSTRACT The enteric nervous system (ENS) is the intrinsic nervous system of the gut and controls essential functions, such as gut motility ...
