Apportioning Sources of Nitrogen Oxides in California's San Joaquin Valley Using Observations From Three Airborne Field Campaigns

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Emissions of nitrogen oxides (NOx = NO + NO2), a precursor to ozone and secondary aerosol formation have become increasingly important to understand as ozone production transitions to NOx limited in most regions of the US. Recent studies suggest that NOx emissions associated with agricultural activities, particularly cropland soils, are an ...

Base‐Free Nickel‐Catalyzed Three‐Component Coupling of Aldehydes, Butadiene, and Malonate Derivatives: Toward Sustainable Synthesis of Highly Functionalized Molecules

European Journal of Organic Chemistry, Volume 29, Issue 39, 22 October 2026.
A nickel‐catalyzed three‐component reaction between arylaldehydes, butadiene, and malonates is developed yielding high functionalized homoallylic alcohols in a single step. No additional base is required and the reaction shows broad substrates compatibility with yields up to 96% and an exclusive selectivity toward the linear E‐isomer.

Sulfur Dioxide Point Sources Remain Important for Daytime Plume‐Scale New Particle Formation in the United States: Case Study for Gary, Indiana During the Summer 2023 AEROMMA Aircraft Campaign

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Plumes from sulfur dioxide (SO2) point sources have been shown to be significant contributors to new particle formation (NPF), but SO2 emissions in the United States (US) have decreased drastically by ∼10× since the early 2000s. We present observations of plume‐scale NPF from SO2 point sources over the industrial hub in Gary, Indiana and ...

Chemoenzymatic Synthesis of (4R,7R)‐Zingiberene Enables Construction of nor‐Sesquiterpene Semiochemical Analogs

ChemBioChem, Volume 27, Issue 19, 14 October 2026.
A five‐enzyme chemoenzymatic synthesis of the insect‐repellent (4R,7R)‐zingiberene from the wild tomato (Solanum habrochaites) has been developed. This approach enabled the elucidation of the sesquiterpene synthase cyclization mechanism of (2Z,6Z)‐farnesyl pyrophosphate and bypasses classic biosynthetic constraints of prenyltransferase chain extension ...

Evolutionary, Functional and Mechanistic Characterisation of Microbial Terpene Synthase‐Like Genes From Springtails

Angewandte Chemie International Edition, Volume 65, Issue 41, 5 October 2026.
A genome analysis revealed the presence of many bacterial‐type terpene synthases in springtails. Four enzymes from Sinella curviseta were functionally characterised, resulting in the isolation of several compounds including sinellene ether, the first diterpene ether identified from a terpene synthase that represents a novel skeleton.

Optimal seasonal schedule for the production of isoprene, a highly volatile biogenic VOC

Scientific Reports
The leaves of many trees emit volatile organic compounds (abbreviated as BVOCs), which protect them from various damages, such as herbivory, pathogens, and heat stress.

El Niño drought and heat extremes suppress soil isoprene uptake capacity in the Amazon rainforest

Communications Earth & Environment
Soils are recognized sinks for atmospheric isoprene, but their in situ behavior remains understudied, particularly in the Amazon where emissions are globally significant.
