Population genomics of heterosporous lycophytes: allopatric speciation and historical persistence through paleoclimatic fluctuations

The Plant Journal, Volume 128, Issue 3, November 2026.
SUMMARY Speciation is the fundamental process driving the origin of earth biodiversity. While speciation mechanisms have been revealed in many plant taxa, the evolutionary dynamics of heterosporous lycophytes remain largely unexplored. Here, we used the Selaginella sanguinolenta group, comprising seven montane species in eastern Asia, as a model system.

Induction of Methuosis in Breast Cancer Stem Cells by a Cobalt(III) Complex Evokes Immunotherapeutic Response

Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.
Cancer stem cells (CSCs) drive metastasis, relapse and resist conventional apoptosis‐inducing chemotherapies. We report a cobalt(III)‐cyclam complex with pyrene and diflunisal moieties that reduces the viability of breast CSCs at low micromolar concentrations.

Bioorthogonal Chemistry in Neurobiology: From Imaging to Proteomics

ChemBioChem, Volume 27, Issue 20, 28 October 2026.
This review highlights emerging strategies for labeling neuronal proteins, enabling visualization and quantitative analysis of their expression, localization, and dynamics. By combining genetic code expansion (GCE), metabolic labeling, and click chemistry‐based labeling, these approaches provide powerful routes to study proteins in specific cells and ...

Characterization and Crystal Structure Elucidation of the l‐Homoserine O‐Succinyltransferase MetXS From Cupriavidus necator H16

ChemBioChem, Volume 27, Issue 20, 28 October 2026.
This study reports the identification, heterologous production, and in vitro characterization of the homoserine O‐succinyltransferase from C. necator (CnMetXS). Several biochemical parameters, including the pH and temperature optima, thermostability, substrate scope, and kinetic parameters, are determined, and a high‐resolution X‐ray structure of ...

Cellular Membrane‐Targeted Europium(III) Probe for Selective and Time‐Resolved Detection of Peroxynitrite

Chemistry – A European Journal, Volume 32, Issue 40, 27 October 2026.
We report a cellular membrane‐targeted europium(III) probe, Eu.Chol, that enables selective, time‐resolved detection of peroxynitrite (ONOO−) at the cell membrane interface. Eu.Chol demonstrates efficient incorporation into liposomes and Jurkat cells, with minimal response to H2O2, establishing a modular platform for subcellular ONOO− sensing ...

Farnesyltransferase Enables Modular Assembly of Dual‐Functional Nanobody Conjugates for in Vivo Imaging of Inflammation

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
A modular farnesyltransferase‐based chemoenzymatic platform enables fast, site‐specific labeling of nanobodies for PET imaging of inflammation. CD11b‐targeted PET agents selectively image myeloid‐driven inflammation, while CD45‐targeted PET agents provide sensitive whole‐body immune mapping.
