Escherichia Species Diversity Across Pristine and Impacted Catchments: Evidence for Avian Sources of Escherichia marmotae in Aotearoa/New Zealand

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Escherichia spp. were obtained from pristine and impacted environments to define community structure and assess potential human health risks. E. coli was more prevalent from sites affected by livestock or human activities, whereas non‐E. coli Escherichia spp. were more prevalent in avian faeces and native forest with fewer faecal sources.

Diazirines Beyond Photoaffinity Labeling: A Comprehensive Overview of Applications in Biological Sciences, Materials Chemistry, and NMR‐Spectroscopy

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
Diazirines are three‐membered, nitrogen‐containing heterocycles that decompose under light or heat to generate carbenes. For the past two decades, they have served mainly as minimally invasive tags in photoaffinity labeling (PAL). More recently, their value as versatile carbene precursors has been recognized.

Lifespan‐Extending Endogenous Metabolites

Aging Cell, Volume 25, Issue 2, February 2026.
Endogenous metabolites act as mediators of longevity by modulating conserved cellular pathways. We summarize mechanistic evidence linking specific metabolites to lifespan and healthspan benefits across model systems, with discussion of clinical evidence, translational opportunities, and remaining knowledge gaps.

Antiseizure Effects of Cannabidiol in Combination With Cannabigerol in the Maximal Electroshock Seizure Model

Basic &Clinical Pharmacology &Toxicology, Volume 138, Issue 2, February 2026.
Cannabidiol and cannabigerol suppress maximal electroshock seizures. Cannabidiol and cannabigerol show similar dose–response properties. Both cannabinoids show no toxicity at effective doses. ABSTRACT Current antiseizure therapy for epilepsy is only effective in about 70% of the patient population.

Influence of Rare Earth Elements on Prebiotic Reaction Networks Resembling the Biologically Relevant Krebs Cycle

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
Rare earth elements can act as mediators in a prebiotic reaction network, producing various intermediates of the citric acid cycle starting from glyoxylate and pyruvate. The ionic radius and the resulting variation in Lewis acidity has a significant influence on the observed product scope.

Synthesis and Application of [18F]Togni Reagent I: An Electrophilic 18F‐Labeled Trifluoromethylating Reagent for Positron Emission Tomography Tracer Synthesis

European Journal of Organic Chemistry, Volume 29, Issue 4, January 26, 2026.
Togni reagent I, one of the most used electrophilic trifluoromethylating reagents, has been radiolabeled with fluorine‐18 starting from the widely available fluoro‐benziodoxole and the [18F]Ruppert–Prakash reagent. To demonstrate the broad potential for late‐stage functionalization, aliphatic carboxylic acids were successfully converted into their 18F ...
