Stimuli‐Responsive Hydrogels for Optical Applications: Mechanisms, Architectures, and Translational Challenges

Aggregate, Volume 7, Issue 6, June 2026.
The review discusses stimuli‐responsive hydrogels as soft optical materials that translate physical, chemical, and biological cues into refractive‐index, scattering, birefringence, diffraction, and transparency changes. It examines major stimulus classes and photonic architectures for biosensing, waveguiding, adaptive lenses, smart windows, and therapy.

On the fourth Diadema species (Diadema-sp) from Japan. [PDF]

PLoS ONE, 2014
Four long-spined sea urchin species in the genus Diadema are known to occur around the Japanese Archipelago. Three species (D. savignyi, D. setosum, and D. paucispinum) are widely distributed in the Indo-Pacific Ocean.

Developmental and Cellular Basis of Vertical Bar Color Patterns in the East African Cichlid Fish Haplochromis latifasciatus

Frontiers in Cell and Developmental Biology, 2020
The East African adaptive radiations of cichlid fishes are renowned for their diversity in coloration. Yet, the developmental basis of pigment pattern formation remains largely unknown.

A Dynamic Change of Microglial States Occurs During the Transition From Photoreceptor Degeneration to Regeneration in Zebrafish pde6c Mutants

Glia, Volume 74, Issue 6, June 2026.
Zebrafish pde6c mutants undergo photoreceptor degeneration from 5 dpf, but rods regenerate from 4 wpf. scRNA‐seq of retinal microglia reveals dynamic change of states between 5 dpf and 4 wpf. Two states emerge specifically during regeneration. ABSTRACT Microglia, brain‐resident immune cells, maintain brain homeostasis.

Variation in pigmentation gene expression is associated with distinct aposematic color morphs in the poison frog Dendrobates auratus

BMC Evolutionary Biology, 2019
Background Color and pattern phenotypes have clear implications for survival and reproduction in many species. However, the mechanisms that produce this coloration are still poorly characterized, especially at the genomic level.

Transient ectopic overexpression of agouti-signalling protein 1 (asip1) induces pigment anomalies in flatfish. [PDF]

PLoS ONE, 2012
While flatfish in the wild exhibit a pronounced countershading of the dorso-ventral pigment pattern, malpigmentation is commonly observed in reared animals. In fish, the dorso-ventral pigment polarity is achieved because a melanization inhibition factor (

Dual Knockout Models of the Spatially and Functionally Conserved rgra and rgrb Zebrafish Genes Reveal the Requirement of RGR for the Integrity of Cone‐Mediated Photopic Vision, the Photopic Visual Cycle and Bruch's Membrane Morphology

The FASEB Journal, Volume 40, Issue 10, 31 May 2026.
This study investigates the role of the vision gene RGR using novel dual knockout zebrafish models. The loss of rgra and rgrb results in zebrafish larvae having reduced visual function and altered retinoid profiles under light but not dark conditions. The OKR phenotype is enhanced under higher light intensities.

Bio‐Inspired Magnetically Tunable Structural Colors from Elliptical Self‐Assembled Block Copolymer Microparticles

Advanced Functional Materials, Volume 36, Issue 38, 11 May 2026.
Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.

Modulation of light localization in the iridophores of the deep-sea highlight hatchetfish Sternoptyx pseudobscura under magnetic field

AIP Advances, 2017
Efficient light control by certain tissue in bioluminescent fish offers potential for new optical devices. In the world’s deep-seas, there are numerous fish species with such bioluminescence yet to be discovered.
