Rapid Arbitrary‐Shape Microscopy of Unsectioned Tissues for Precise Intraoperative Tumor Margin Assessment

open access: yesAdvanced Science, Volume 13, Issue 8, 9 February 2026.
This study presents a novel microscopic imaging system capable of rapid, section‐free scanning of irregular tissue surfaces, delivering high sensitivity for detecting cancer cell clusters during intraoperative tumor margin assessment. Abstract Rapid and accurate intraoperative examination of tumor margins is crucial for precise surgical treatment, yet ...

Enhanced deoxyviolacein bioproduction via enzyme condensation with a yeast glycolytic enzyme‐derived peptide tag

open access: yesBiotechnology Progress, Volume 42, Issue 1, January/February 2026.
Fusion of a 27‐amino‐acid peptide tag derived from a glycolytic enzyme enabled artificial assembly formation of the two violacein biosynthetic enzymes, VioE and VioC. This assembly resulted in enhanced biosynthesis of deoxyviolacein. Abstract In microbial production, regulating endogenous and exogenous synthetic pathways is essential.

Chasing (macro)elements in microinvertebrates: A new methodological approach for quantitative and qualitative analyses of phosphorus by PIXE (Particle‐Induced X‐Ray Emission) applied to glacier tardigrades

open access: yesMethods in Ecology and Evolution
Microinvertebrates in harsh environments often occupy the highest trophic levels and directly influence the turnover of macroelements. However, the investigation of their body elemental composition is complicated due to their low dry weight or sample ...

Synchrotron Micro‐X‐Ray Fluorescence Elemental Imaging Reveals Zinc Distribution in the Hyperaccumulator Sedum plumbizincicola (Crassulaceae)

open access: yesEcological Research, Volume 41, Issue 1, January 2026.
Sedum plumbizincicola is a zinc‐cadmium hyperaccumulator native to China with high potential for use in phytoremediation. Synchrotron micro‐X‐ray fluorescence elemental imaging shows that zinc is localized in the leaf tips, petioles, and nodes with the highest Zn concentrations observed in the epidermis and vascular system of both leaves and stems ...

Crossing scales and eras: Correlative multimodal microscopy heritage studies

open access: yesJournal of Microscopy, Volume 301, Issue 1, Page 40-68, January 2026.
Abstract The comprehensive characterisation of complex, irreplaceable cultural heritage artefacts presents significant challenges for traditional analytical methods, which can fall short in providing multi‐scale, non‐invasive analysis. Correlative Multimodal Microscopy (CoMic), an approach that integrates data from multiple techniques, offers a ...

Spectroscopic techniques in the investigation of extraordinary medieval Polish coins: Revealing the presence of hidden cores

open access: yesNukleonika
Cross denars, frequently found in Polish hoards, were traditionally thought to be Ag coins with some Cu content. This study investigates the possibility of a hidden Cu core beneath the Ag or Ag–Cu surface of these coins. It raises questions about whether
