Ultrasensitive bionic photonic-electronic skin with wide red-shift mechanochromic response
Mimicking animal skin is an effective strategy for enhancing the performance of artificial skin. Inspired by a chameleon’s iridophore and a spider’s slit organ, a novel photonic-electronic skin (PE-skin) with excellent optical/electrical dual-sensing ...

The Evolution of Giant Clam Science: From Foundational Studies to Emerging Frontiers
This review synthesizes nearly two centuries of giant clam research, identifying dominant themes, knowledge gaps, and emerging opportunities. Ecology, physiology, aquaculture, genomics, and biomineralization dominate the field, whereas anatomy and biotechnology remain underexplored. Future progress requires stronger integration of genomics, physiology,

Mitochondrial DNA depletion syndromes (MDS) are a group of rare autosomal recessive disorders with early onset and no cure available. MDS are caused by mutations in nuclear genes involved in mitochondrial DNA (mtDNA) maintenance, and characterized by ...

High Contrast Markings Can Negate the Benefits of Transparent Camouflage
Transparency is perhaps theoretically the most efficient means of achieving camouflage; however, in application, species show considerable variance in their degree of transparency. We demonstrate the fragility of transparent camouflage, detailing how imperfections reduce efficacy with implications in predation risk. ABSTRACT Transparency is, in theory,

Post‐Oviposition Embryonic Staging Scheme for the Delicate Skink, Lampropholis delicata
We detail the morphology of post‐oviposition embryos throughout development and compare it with reptilian embryonic staging schemes from other squamates. We identified 16 embryo stages based on the development of limbs, eyes, brain, branchial arches, frontonasal prominence, otic vesicle, scales, and pigmentation.

The Genetic Basis of Color Polymorphism in the Orb‐Web Spider Gasteracantha cancriformis [PDF]
This study investigates the genetic basis of coloration in the polymorphic spider Gasteracantha cancriformis using RNA‐seq data from different female color morphs. We assembled a reference transcriptome and identified differentially expressed genes associated with known pigmentation pathways, including carotenoids, melanin, ommochromes, and pteridines.

Stress‐induced changes in color expression mediated by iridophores in a polymorphic lizard [PDF]
AbstractStress is an important potential factor mediating a broad range of cellular pathways, including those involved in condition‐dependent (i.e., honest) color signal expression. However, the cellular mechanisms underlying the relationship between stress and color expression are largely unknown.

Heterotypic interactions regulate cell shape and density during color pattern formation in zebrafish
The conspicuous striped coloration of zebrafish is produced by cell-cell interactions among three different types of chromatophores: black melanophores, orange/yellow xanthophores and silvery/blue iridophores.

Biomimetic Iridescent Skin: Robust Prototissues Spontaneously Assembled from Photonic Protocells
Uniform nanoparticles are induced to form arrays (photonic crystals) in the cores of biopolymer capsules, endowing these ‘protocells’ with structural color. These protocells are then assembled into large self‐standing objects, i.e., prototissues, with robust mechanical properties as well as iridescent optical properties.
