  • In the river Rhine, almost 70% of litter particles above 1 cm in diameter are plastics, most of which come from single-use items, often from private consumers, but they comprise less than 15% of all litter by weight, according to continuous monitoring over 16 months with a custom-made physical-interception litter trap.

  • Acetylenes can be covalently linked by oxidative coupling reactions. Zhanget al. report terminal alkyne Csp-H bond activation and concomitant homo-coupling on a silver surface, yielding polymeric networks with a conjugated backbone.

  • Extending the π‐conjugation of phthalocyanine dyes, while synthetically challenging, has the potential to produce desirable new molecular materials. Here, the authors use a templated on‐surface approach to synthesize several extended phthalocyanine derivatives from the same building block, including a lanthanide superphthalocyanine and an open‐chain polycyanine.

  • In wildlife tagging, stress from capture and handling can alter post- release behavior and potentially study interpretations. This study of 42 mammal species shows that these effects diminish within 4–7 days, and quicker for animals in high human activity areas indicating adaptation to disturbance.

  • Paul Pharoah and colleagues report the results of a large genome-wide association study of ovarian cancer. They identify new susceptibility loci for different epithelial ovarian cancer histotypes and use integrated analyses of genes and regulatory features at each locus to predict candidate susceptibility genes, including OBFC1.

  • John Perry, Ken Ong and colleagues analyze genotype data on ∼370,000 women and identify 389 independent signals that associate with age at menarche, implicating ∼250 genes. Their analyses suggest causal inverse associations, independent of BMI, between puberty timing and risks for breast and endometrial cancers in women and prostate cancer in men.

  • Georgia Chenevix-Trench and colleagues report meta-analyses of genome-wide association studies identifying six loci newly associated with epithelial ovarian cancer (EOC). They also test variants at the 12 known and 6 new EOC susceptibility loci for association in BRCA1 and BRCA2 mutation carriers.
