Modern Agriculture, Volume 4, Issue 2, December 2026.Consoli et al. mapped eight Chl f‐binding sites in far‐red‐light‐acclimated photosystem I (FR PSI). Structural and spectroscopic evidence supports the involvement of Chl f at the A−1B site in primary charge separation and indicates that its protein microenvironment modulates redox properties.

Food Science &Nutrition, Volume 14, Issue 11, November 2026.Rosa rugosa root extract (RR‐r) attenuated UVB‐induced wrinkle formation and collagen degradation while improving skin hydration. Its photoprotective effects were associated with modulation of MAPK/AP‐1 and AGE‐RAGE signaling. ABSTRACT Rosa rugosa root extract (RR‐r) has been used in East Asian medicine to treat metabolic disorders, including diabetes ...

Stemonine Alleviates UVB‐Induced Keratinocyte Senescence by Activating SIRT3
Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 11, November 2026.Stemonine, a natural alkaloid, protects human HaCaT keratinocytes against UVB‐induced skin senescence. Stemonine attenuated oxidative stress, mitochondrial dysfunction, DNA damage, and key senescence markers. It functioned by upregulating the expression and activity of SIRT3.

The Cutaneous Melatoninergic System: Endogenous Biology and Potential for Therapeutic Targeting
Experimental Dermatology, Volume 35, Issue 11, November 2026.ABSTRACT Melatonin is best known as a pineal hormone that regulates circadian rhythms, but the skin also possesses an intrinsic melatoninergic system capable of local synthesis, metabolism and signalling. This system encompasses classical melatonin receptors, biologically active metabolites, non‐classical signalling pathways and receptor‐independent ...

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.A hybrid “confocal” electrochemiluminescence (ECL) microscopy combines depth‐resolved and time‐resolved imaging to visualize ECL processes across three spatial dimensions and time. By exploiting sluggish coreactant kinetics at ITO electrodes, homogeneous redox propagation enables depth‐resolved, single‐cell resolution mapping of living multicellular ...

Plant, Cell &Environment, Volume 49, Issue 11, Page 8497-8508, November 2026.ABSTRACT Tropospheric ozone (O3) reduces crop productivity, but the sites at which ozone alters photosynthetic electron transport remain unclear. We tested whether acute exposure to O3 shifts the dominant site of electron transport limitation in a cultivar‐specific manner, rather than causing a uniform decline in PSII function.

Flavin Catalysts in Organic Synthesis
Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.
