Crosslinked Poly(Acrylic Acid‐Co‐Acrylamide) Applied to Remove Hg(II) and the Effects of Its Exposure on Girardia tigrina

Polymer Engineering &Science, Volume 65, Issue 12, Page 6964-6979, December 2025.
The polymeric adsorption of Hg(II) and the assessment of ecotoxicity. ABSTRACT In this study, an adsorbent was produced by the copolymerization of acrylic acid and acrylamide, followed by cross‐linking. The impact of pH, duration of contact, concentration, presence of interfering ions, and reuse was investigated.

In situ probe and inhibitory RNA synthesis using streamlined gene cloning with Gibson assembly

STAR Protocols, 2022
Summary: The synthesis of single-stranded riboprobes or double-stranded RNAs for in situ hybridization and gene knockdowns often use vectors that require time-consuming plasmid restriction digests and inefficient gel purifications.

Cell lineage tracing: Methods, applications, and challenges

Quantitative Biology, Volume 13, Issue 4, December 2025.
Abstract Cell lineage tracing is a crucial technique for understanding cell fate and lineage relationships, with wide applications in developmental biology, tissue regeneration, and disease progression studies. Over the years, experimental cell lineage tracing methods have advanced from early labeling techniques to modern genetic tools such as CRISPR ...

Genome-Wide Analysis of Polyadenylation Events in Schmidtea mediterranea

G3: Genes, Genomes, Genetics, 2016
In eukaryotes, 3′ untranslated regions (UTRs) play important roles in regulating posttranscriptional gene expression. The 3′UTR is defined by regulated cleavage/polyadenylation of the pre-mRNA.

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 ...

Regenerate to “Rejuvenate”: Insights From Adult Resident Stem Cells of Aged Flatworms and Mice

Aging Cell, Volume 24, Issue 11, November 2025.
Resident stem cells from aged planaria and murine skeletal muscle possess some inherent abilities to mitigate signs of aging after tissue regeneration. ABSTRACT Adult resident stem cells are capable of regenerating tissues that manifest signs of “rejuvenation” in flatworms and mice of older ages.

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.

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 ...

Vertically- and horizontally-transmitted memories – the fading boundaries between regeneration and inheritance in planaria

Biology Open, 2016
The Weismann barrier postulates that genetic information passes only from the germline to the soma and not in reverse, thus providing an obstacle to the inheritance of acquired traits.
