Light sensing starts with phototransduction in photoreceptor cells. The phototransduction cascade has diverged in different species, such as those mediated by transducin in vertebrate rods and cones, by G(q)-type G protein in insect and molluscan rhabdomeric-type visual cells and vertebrate photosensitive retinal ganglion cells, and by G(o)-type G protein in scallop ciliary-type visual cells. H...

BACKGROUND Jellyfish envenomation is common along the coastal area, and can cause severe consequences. Naval personnel are among the high-risk population for this injury. The aim of this study was to assess knowledge regarding jellyfish envenomation among naval personnel in a navy unit in northeast China. METHODS A predesigned questionnaire was distributed to 120 naval members in January 2015...

We developed a capillary zone electrophoresis method with indirect UV detection for determination of ammonium cations and alkali and alkaline earth metal cations in jellyfish. As the background electrolyte, a mixture of N-methylbenzylamine, citrate, and 18-crown-6 was used for the complete separation of all analyte cations. The limits of detection were 0.13 - 0.34 mg l(-1) at a signal-to-noise ...

Over the past half century fishing has led globally to a reduction in the mean trophic level of commercially landed species, with a significant decline from large predatory fish toward plankton-eating pelagic species and low trophic-level invertebrates [1]. An implied endpoint of this ‘fishing down marine food webs’ is a proliferation of previously suppressed gelatinous plankton (jellyfish) [2]...

On March 11, 1950, The Mail, a newspaper published in Adelaide, South Australia, ran the headline “Tiny African jellyfish SA reservoir”. A freshwater? Who would not be interested by that? Admittedly, paper did get some stuff wrong: this creature, Craspedacusta sowerbii (Figure 1), is from “Great Lakes of Tanganyika”, as story implies. And journalist’s scientific source, Mr Ifor Thomas Adelaide ...

Numerous examples of ram pressure stripping in galaxy clusters are present literature; however, substantially less work has been focused on lower mass groups. In this we use the LOFAR Two-metre Sky Survey (LoTSS) to search for jellyfish galaxies ~500 SDSS groups (z<0.05), making most comprehensive date. We identify 60 with extended, asymmetric radio continuum tails, which found across entire ra...
