Theoretical considerations of eye design allow us to find routes along which the optical structures eyes may have evolved. If selection constantly favours an increase in amount detectable spatial information, a light-sensitive patch will gradually turn into focused lens through continuous small improvements design. An upper limit for number generations required complete transformation can be calculated with minimum assumptions. Even consistently pessimistic approach time becomes amazingly...
ABSTRACT The nature of the control glycolytic flux is one central, as-yet-uncharacterized issues in cellular metabolism. We developed a molecular genetic tool that specifically induces ATP hydrolysis living cells without interfering with other aspects Genes encoding F 1 part membrane-bound (F 0 ) H + -ATP synthase were expressed steadily growing Escherichia coli cells, which lowered intracellular [ATP]/[ADP] ratio. This resulted strong stimulation specific concomitant smaller decrease growth...
Abstract UV vision is prevalent, but we know little about its utility in common general tasks, as resolving habitat structure. Here visualize vegetated habitats using a multispectral camera with channels mimicking bird photoreceptor sensitivities across the UV-visible spectrum. We find that contrast between upper and lower leaf surfaces higher channel than any visible channel, this makes position orientation stand out clearly. This was unexpected since both reflect similarly small...
SUMMARY Box jellyfish, cubomedusae, possess an impressive total of 24 eyes four morphologically different types. Two these eye types, called the upper and lower lens eyes, are camera-type with spherical fish-like lenses. Compared other cnidarians, cubomedusae also have elaborate behavioral repertoire, which seems to be predominantly visually guided. Still, positive phototaxis is only behavior described so far that likely correlated eyes. We explored obstacle avoidance response Caribbean...
Most known starfish species possess a compound eye at the tip of each arm, which, except for lack true optics, resembles an arthropod eye. Although these eyes have been about two centuries, no visually guided behaviour has ever directly associated with their presence. There are indications that they involved in negative phototaxis but this may also be governed by extraocular photoreceptors. Here, we show coral-reef-associated Linckia laevigata slow and colour blind. The capable image...
Quantifying and comparing light environments are crucial for interior lighting, architecture visual ergonomics. Yet, current methods only catch a small subset of the parameters that constitute environment, rarely account reaches eye. Here, we describe new method, environmental field (ELF) which quantifies all essential features characterize including important aspects have previously been overlooked. The ELF method uses calibrated digital image sensor with wide-angle optics to record...
Earlier detailed studies of cnidarian planula larvae have revealed a simple nervous system but no eyes or identifiable light sensing structures. Here, we describe the box jellyfish, Tripedalia cystophora, and report that these an extremely organization with at all. Their only advanced feature is presence 10-15 pigment-cup ocelli, evenly spaced across posterior half larval ectoderm. The ocelli are single cell structures containing cup screening pigment filled presumably photosensory...
