UV-reflective dragonfly wax is shown to consist of very long-chain methyl ketones and aldehydes, and a synthetic dragonfly wax spontaneously forms light-scattering fine structures with strong UV reflection.

Variation in patterns of floral UV pigmentation is controlled by a single transcription factor in sunflower and affects both pollinator attraction and responses to environmental stresses.

Artificial selection on wing color and CRISPR/Cas9 knockout of the optix gene both alter scale lamina thickness in Junonia coenia, which shifts structural color wavelength and mimics macroevolutionary butterfly diversity.

Genome-wide mapping of heteroduplex DNA (a recombination intermediate) formed during mitotic recombination in yeast demonstrates that the "classical" model of double-strand DNA break repair is inadequate to explain several aspects of mitotic recombination.

A modelling-based analysis reveals a novel type of selectivity for chromatic contrast in a mouse retinal ganglion cell type, and experimental evidence shows that this feature makes this cell type well suited for detecting behaviourally relevant changes in visual context.

A sophisticated classical mutagenesis assay with next-generation sequencing technology presents a benefit to future research on mutagenesis, DNA repair, and cancer.

A complex colour polymorphism which links colour with behavioural and life-history traits is associated with a single gene duplication in male wood tiger moths.

Analysis of 458 Kalinago provides new insights into the population's genetic structure, the contribution of Native American ancestry to skin pigmentation, and the identification of a coding variant in OCA2 with an estimated –8 melanin units effect size.

Many vertebrates are able to synthesize a sunscreen compound de novo and the pathway involved can be used for heterologous production of the compound in yeast.

Identifying 1,907 mitochondrial somatic mutations from 1,675 tumor tissues provides new insights into the causes and effects of the mitochondrial genome mutations found in human cancers.
