What is the function of saccadic suppression, wherein visual sensitivity is reduced around eye movements? This study traces long-lasting saccadic suppression in zebrafish and presents evidence suggesting that it may enhance the salience of relevant stimuli.

The image shows a side view of a fluorescent larval zebrafish with the optic tectum labelled in magenta color. Image credit: Giulia Soto, Aristides Arrenberg. Rapid eye movements help animals actively sample their visual surroundings, but they can also disrupt incoming visual information. Saccadic suppression – a reduction in visual sensitivity around these movements – may help shape what the brain notices. Soto et al. found that saccadic suppression in zebrafish arises through distributed sensory and motor mechanisms, which they measured across the visual system. In the optic tectum, suppression of visual responses is weaker for prey-like moving dots and looming threats than for global flashes. Thus, behaviorally relevant cues are more prominent in the optic tectum after a saccade than irrelevant cues. This saliency filtering could help the brain prioritize useful information with limited neural resources.

A Gata4–Loxl2 axis controls ECM remodeling to enable scar-free spinal cord regeneration in zebrafish
Fibrotic scar formation prevents successful spinal cord regeneration in mammals. Noel et al. identify a Gata4–Loxl2 signaling axis that suppresses pathological extracellular matrix remodeling and enables scar-free regeneration in zebrafish.

Most blue coloration in animals is structural, not pigments & relies on biogenic guanine crystals.

Guanine is the "G" base in your DNA.

When crystallized in a living cell, it forms thin layers of high refractive index like a thin mirror. Stack these up & you get prismatic color.
Fig. 1: Intracellular electron-dense organelles are abundant in zebrafish larval iridophores. a, Incident light image of zebrafish larva at 5 days post fertilization (dpf), showing guanine crystals in the eyes and skin. Inset, higher-magnification view of the eye region (highlighted in pink). b, Confocal microscopy images of a 96 hpf zebrafish larval eye showing mCherry-labeled iridophores driven by the pnp4a promoter, a known iridophore marker45 (Tg(pnp4a:PALM-mCherry), red). Guanine crystal reflectance is shown in white. Inset, higher-magnification view of a single iridophore (yellow frame); cell boundaries are marked with a cyan dashed line. c, A 3D surface rendering of representative cryo-FIB-SEM data showing a portion of a single eye iridophore at 72 hpf. Nanometer-scale membrane-bound organelles are segmented in yellow and guanine crystals are segmented in blue. ER, endoplasmic reticulum. Field of view: 9.3 × 12.4 μm, with a depth of 2.7 μm. In total, dozens of cells from four different fish were imaged across multiple cryo-FIB-SEM sessions. d, Cryo-TEM micrographs of iridosomes at different maturation stages from zebrafish larvae.
