A Mechanical sp2‐Jail for C60 Fullerene

Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.
A rigid bisporphyrin receptor with an exceptionally compact 3D cavity functions as a molecular “mechanical jail”, tightly enclosing C60 fullerene. Near‐perfect shape complementarity affords ultrahigh binding affinity while imposing a large kinetic barrier for guest exchange, rendering encapsulation effectively irreversible under ambient conditions ...

Methionine Regulates Antitumour Function of CD8+ T Cells Through Polyamine Synthesis

Immunology, Volume 179, Issue 3, Page 418-433, November 2026.
Methionine restriction in vitro enhances CD8+ T cell effector function by suppressing polyamine synthesis and progressively induces the co‐expression of PD‐1 and TIM‐3. Consistently, sustained dietary methionine restriction diminishes the efficacy of adoptive T cell therapy (ACT) and promotes the expression of terminal exhaustion‐associated markers ...

Substrate‐Dependent Crosslinking by the Cytochrome P450 From Aminopyruvatide Biosynthesis

Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.
Substitutions in the aminopyruvatide precursor peptide altered the C─C linkage formed from a YLY motif by the P450 ApyO to a N─C linkage in a WLY motif. Moreover, constitutional isomers crosslinked by C─C and C─O linkages were formed from YYY or YWY motifs. ABSTRACT Cytochrome P450s catalyze an array of reactions including crosslinking of aromatic side

Enrichment‐Based Duplex PCR for Early Detection of Potentially Virulent Vibrio harveyi in Aquaculture

Journal of Fish Diseases, Volume 49, Issue 11, November 2026.
ABSTRACT Vibrio harveyi is an important bacterial pathogen in marine aquaculture, responsible for outbreaks affecting a wide range of fish species. Early detection of potentially virulent isolates in fish and environmental samples is essential for effective disease prevention and management, particularly under field conditions where the pathogen may be

Metal–Metal Cooperative C─F and S─F Bond Cleavage by Low‐Valent Tetracobalt Clusters and Water‐Assisted Fluoroarene Hydrodefluorination

Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.
Self‐assembled tetrahedral CoI4 clusters supported by simple bipyridine‐based ligands undergo core rearrangement to cleave S─F and C(sp2)─F bond, forming fluoride‐bridged tetracobalt(II)‐oxo clusters, while exposure of cobalt(I) clusters to molecular oxygen yields cubane‐type cobalt(III) oxo clusters.

Between Skin and Brain: A Systematic Review of 712 Cases 1976–2025 Reveals a Highly Diverse Disease Spectrum in Chaetothyriales

Mycoses, Volume 69, Issue 11, November 2026.
ABSTRACT Background Black yeast‐like species of the order Chaetothyriales cause superficial to life‐threatening systemic infections. Comprehensive global epidemiology data remain limited. Objectives This study aimed to analyze the global epidemiology, spectrum of pathogens, clinical manifestations and outcomes of Chaetothyriales infections.
