Physiological basis of resolution acuity in vision
Nature CommunicationsVision is the primary sensory modality for many animals, especially humans and other primates. A fundamental constraint on visual resolution acuity is set by the size and spacing of cone photoreceptors, notably in the fovea of the retina where cones are ...

Defect‐Mediated Inelastic Light Scattering by Infrared Phonons in Hexagonal Boron Nitride
Advanced Functional Materials, EarlyView.Optically active defects in hexagonal boron nitride enable inelastic stimulated light scattering mediated by infrared‐active phonons, relaxing conventional Raman selection rules. Defect engineering enhances the Stokes‐conversion process and activates both TO‐ and LO‐phonon scattering channels.

Human foveal cone photoreceptor topography and its dependence on eye length
eLife, 2019 We provide the first measures of foveal cone density as a function of axial length in living eyes and discuss the physical and visual implications of our findings.

Advanced Functional Materials, EarlyView.For the first time, an extreme‐thick laser‐arc PVD ta‐C (DLC) coating exceeding 100 µm is demonstrated, opening up new possibilities for ultra‐high load bearing capacity. This superhard amorphous carbon architecture combines >50% sp3 bonding, robust adhesion and self‐supporting performance, shielding substrates from plastic flow under extreme contact ...

fMRI and gene therapy in adults with CNGB3 mutation
Brain Research BulletinAchromatopsia is an inherited retinal disease that affects 1 in 30,000–50,000 individuals and is characterised by an absence of functioning cone photoreceptors from birth.

The role of retinol dehydrogenase 10 in the cone visual cycle
Scientific Reports, 2017 Pigment regeneration is critical for the function of cone photoreceptors in bright and rapidly-changing light conditions. This process is facilitated by the recently-characterized retina visual cycle, in which Müller cells recycle spent all-trans-retinol

Advanced Healthcare Materials, EarlyView.In this study, Hammer et al. highlight cyclic‐arginine surface engineering as a highly biocompatible, controllable, and concentration‐dependent regulator of intravitreal nanoparticle mobility in vivo in a translational large animal model. The cyclic arginine surface‐modification supports the development of next‐generation biomaterials for long‐acting ...
