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.

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 ...

Characterizing Emerging Detector Materials for Low‐Dose X‐Ray Imaging

open access: yesAdvanced Materials, Volume 37, Issue 45, November 13, 2025.
X‐ray medical imaging requires detectors that deliver images at as low as reasonably possible dose. This perspective outlines a universal characterization framework of X‐ray imaging detectors, suitable for both emerging semiconductor and scintillator materials, introduces a novel unified figure of merit that links dose with resolution, and offers an ...

Iron and ferritin accumulate in separate cellular locations in Phaseolus seeds

open access: yesBMC Plant Biology, 2010
Background Iron is an important micronutrient for all living organisms. Almost 25% of the world population is affected by iron deficiency, a leading cause of anemia. In plants, iron deficiency leads to chlorosis and reduced yield. Both animals and plants

The Pace di Siena and its Gems

open access: yesJournal of Raman Spectroscopy, Volume 56, Issue 11, Page 1254-1278, November 2025.
For the first time, the gems of the Pace di Siena, a rare en ronde bosse enamel preserved in Arezzo (Italy), have been analyzed using a transdisciplinary approach. The combination of gemmology and Raman spectroscopy has led to the identification of blue sapphires and pink spinels, contradicting previous historical classifications.
