Molecular evolution of terpene synthase underlying the diversification of isoprene emission in Fagaceae

open access: yesPlant Biology, EarlyView.
Isoprene emission in oaks originated from convergent adaptive evolution of terpene synthases, involving a substrate shift from monoterpene to isoprene production within a Fagaceae‐specific TPS lineage. Abstract Plants emit a wide range of volatile organic compounds, among which isoprene is the most abundant and atmospherically influential. Although oak

Airborne Observations Reveal Underestimated Riverine Methane Emissions Across the Amazon

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Strongly increasing trends in global methane in recent decades highlight the importance of understanding source‐sink attributions and climate feedback mechanisms, especially for large natural sources like wetlands. Here, we present an analysis of airborne methane observations above the Amazon Basin conducted from December 2022 through January ...

Design of Experiments‐Based Optimization of Recovered Carbon Black–Reinforced Isobutylene–Isoprene Rubber in Comparison With Conventional Carbon Black Systems

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 27, July 15, 2026.
Optimized potential of rCB via DOE: recovered carbon black from end‐of‐life tires was assessed as a full substitute for conventional carbon black in IIR composites. DOE and response surface methodology optimized rCB loading, plasticizer, and sulfur contents. Hardness showed linear trends, while rupture energy was nonlinear.

Active and Versatile ROP Aluminum Catalysts for the Controlled Limonene Oxide Polymerization and Copolymerization With Anhydrides

open access: yesChemCatChem, Volume 18, Issue 13, 14 July 2026.
Highly active aluminum catalysts for the ring‐opening copolymerization of LO and PA able to produce syndiotactic alternating copolyester within 3 h are presented. The role of DMAP as cocatalysts for the copolymerization is key and is involved in the opening of the anhydride, however, it blocks the catalytic activity for the LO ROP.

Chlorine‐Free Synthesis of P‐Esters: Microwave‐Assisted Direct Esterification of Phosphinic, Phosphonic, as Well as Phosphoric Acid Derivatives

open access: yesChemistry–Methods, Volume 6, Issue 7, July 2026.
The esterification of phosphinic, phosphonic, and phosphoric acids is not possible due the high enthalpy of activation. However, the barrier may be overcome under MW irradiation to give phosphinates, phosphonates, and alkoxyphosphoric acids, respectively. In the latter cases, the remaining P(O)OH group was esterified by alkylation.

Effect of Light Intensity on the Production of Volatile Organic Compounds by Submerged Macrophyte Vallisneria natans in Different Growth Periods

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
In this study, we investigated the effects of growth period and light intensity on BVOCs production in the submerged macrophyte V. natans using a controlled experiment with three light treatments. The results showed that BVOCs production in submerged macrophytes is jointly regulated by plant growth cycles and underwater light intensities and cannot be ...

Advances in the Study of Endometrial Receptivity and Glucose Metabolism Mechanisms in Insulin Resistance

open access: yesEndocrinology, Diabetes &Metabolism, Volume 9, Issue 4, July 2026.
This article systematically reviews how insulin resistance (IR) disrupts endometrial receptivity by interfering with glucose metabolism mechanisms, ultimately leading to infertility in patients with Polycystic Ovary Syndrome (PCOS). ABSTRACT Introduction Insulin resistance (IR) is one of the important pathologic bases of polycystic ovary syndrome (PCOS)
