Insect Science, EarlyView.Jewel beetles can discriminate leaf feeding sites and bark oviposition sites based upon the opponent comparison of their blue, green, and red photoreceptor signals. Through this mechanism, green traps resemble leaves, and purple traps resemble bark, explaining their different attractiveness to males and females.

Can quantum physics help solve the hard problem of consciousness? A hypothesis based on entangled spins and photons [PDF]
Journal of Consciousness Studies 26, 204 (2019), 2018 The hard problem of consciousness is the question how subjective experience arises from brain matter. I suggest exploring the possibility that quantum physics could be part of the answer. The simultaneous unity and complexity of subjective experience is difficult to understand from a classical physics perspective.

Aging Cell, Volume 24, Issue 5, May 2025.Healthy aging is accompanied by transcriptional dysregulation in retinal cells, leading to alterations in key molecular pathways and cellular responses, with the scotopic pathway being particularly affected. We show that rod photoreceptors, essential for initiating scotopic (low‐light) vision, exhibit selective vulnerability to aging‐associated ...

Thermal constraints on in vivo optogenetic manipulations. [PDF]
, 2019 A key assumption of optogenetics is that light only affects opsin-expressing neurons. However, illumination invariably heats tissue, and many physiological processes are temperature-sensitive.

Molecular and cellular mechanisms underlying gyrate atrophy: Why is the retina primarily affected?
Acta Ophthalmologica, EarlyView.Abstract Gyrate atrophy of the choroid and retina (GACR; OMIM #258870) is a rare early‐onset autosomal recessive disorder, caused by bi‐allelic pathogenic variants in the gene coding for ornithine aminotransferase (OAT) resulting in hyperornithinaemia.

The Dynamic Evolutionary History of Pancrustacean Eyes and Opsins.
Integrative and Comparative Biology, 2015 Pancrustacea (Hexapoda plus Crustacea) display an enormous diversity of eye designs, including multiple types of compound eyes and single-chambered eyes, often with color vision and/or polarization vision.

Monogenic Retinal Diseases Associated With Genes Encoding Phototransduction Proteins: A Review
Clinical &Experimental Ophthalmology, Volume 53, Issue 3, Page 260-280, April 2025.ABSTRACT Phototransduction, the process by which captured photons elicit electrical changes in retinal rod and cone cells, represents the first neuronal step in vision and involves interactions between several highly specialised proteins. Pathogenic variants in genes encoding many of these proteins can give rise to significant vision impairment ...

Sequence, Structure, and Expression of Opsins in the Monochromatic Stomatopod Squilla empusa.
Integrative and Comparative Biology, 2018 Most stomatopod crustaceans have complex retinas in their compound eyes, with up to 16 spectral types of photoreceptors, but members of the superfamily Squilloidea have much simpler retinas, thought to contain a single photoreceptor spectral class.
