Angewandte Chemie International Edition, Volume 65, Issue 29, 13 July 2026.A linear polymer, poly(2,3‐dihydroxynaphthalene), when insolubilized, leads to self‐assembly into a hydroquinone–quinone donor+acceptor semiconducting architecture through H‐bonding and π‐stacking interactions. The polymer behaves as a heterogeneous photocatalyst in water for H2O2 production via water oxidation and O2 reduction under visible light.

Batteries From Reused, Recycled, and Surplus Materials
Advanced Sustainable Systems, Volume 10, Issue 7, July 2026.Batteries can become more circular by combining reuse, direct recycling, metallurgical recovery, and material sourcing from industrial surplus streams. This Review highlights how recycled and waste‐derived metals, carbons, polymers, electrolytes, and active materials can be reintegrated into current and emerging batteries, while emphasizing design ...

Emerging infectious disease selects for darker plumage coloration in greenfinches
Frontiers in Ecology and Evolution, 2014 Outbreaks of emerging infectious disease offer a unique chance to study viability selection in action in short time windows. Finch trichomonosis, caused by a protozoan Trichomonas gallinae emerged in Great Britain in 2005 and led to epidemic mortality ...

Advanced Science, Volume 13, Issue 38, 9 July 2026.This work introduces state‐convergent polymerization (SCP), a polymerization framework in which chemically diverse reaction pathways converge toward a reproducible functional polymeric state rather than a defined molecular structure. Using melanin and polydopamine as exemplars, SCP explains how robust polymer functions emerge under chemical and ...

Segmental Hair Analysis of Diphenhydramine and Cyclizine Following a Single Dose
Drug Testing and Analysis, Volume 18, Issue 7, Page 877-892, July 2026.A single oral dose of diphenhydramine and cyclizine can be quantified in human head hair for a minimum of 5 months and, in certain cases, for up to 1 year following intake. Among 12 study participants, the measured concentrations ranged from 0 to 610 pg/mg within 1 year post‐intake.

Ibis, Volume 168, Issue 3, Page 985-1001, July 2026.High colour variability in animals has been associated with adaptability to environmental change. Establishing how such variability is distributed in time and space, and identifying environmental correlates, can help understand the processes driving it.

Transcriptome Comparison Reveals Key Components of Nuptial Plumage Coloration in Crested Ibis
Biomolecules, 2020 Nuptial plumage coloration is critical in the mating choice of the crested ibis. This species has a characteristic nuptial plumage that develops from the application of a black sticky substance, secreted by a patch of skin in the throat and neck region ...

High‐Resolution Elemental Analysis of Neuromelanin‐Containing Organelles in Human Locus Coeruleus
Journal of Neurochemistry, Volume 170, Issue 7, July 2026.Created in https://BioRender.com. Neuromelanin (NM), a dark metal‐chelating pigment in the brain, has long been of interest for its potential roles in aging and Parkinson's disease. In this study, we explored NM‐containing neurons (NM neurons) in the human locus coeruleus at unprecedented resolution.
