The overall energy conversion efficiency is calculated for a bacterial vesicle that harvests solar energy for ATP production on the basis of an atomic-detail structural model.

Visual pigments with a longer peak-absorption wavelength or an open chromophore-binding pocket are generally noisier, being more prone to spontaneous activity.

Single-cell transcriptomics correlated with in situ gene expression analysis provide an overview of the diversity and molecular features of cell types in the squid Loligo vulgaris.

Time-resolved crystallography provides insight into the photochemical reactions in photoreceptor proteins, explaining the earliest steps of how plants, fungi and bacteria sense red light.

Melanophores and xanthophores interact via heteromeric gap junctions composed of Connexin 41.8 and Connexin 39.4 to establish the adult pigment pattern in zebrafish.

The changes in shape of iridophores that underlie adult colour pattern formation in zebrafish depend on the levels of Tight Junction Protein 1a in these cells.

Single-cell dissection of recent neural crest derivatives in the vertebrate zebrafish reveals diverse transcriptomic signatures among differentiating posterior cell types during the embryonic to larval stage transition.

The retinoid-binding protein RLBP1 in the retinal pigment epithelium is crucially involved in cone photoreceptor visual pigment recycling and mimics the human eye disease with retinal lipid deposits when mutated.

In the zebrafish relative Danio albolineatus, red erythrophores share a common progenitor with yellow xanthophores and require Cyp2ae2 and Bdh1a for accumulation of red ketocarotenoid pigment.

A novel B12 containing photoreceptor is synthesized as two different isoforms that interact with the same transcription factor, with one isoform directing activation and the other promoting repression of photosystem synthesis.
