Nociceptors are receptors that detect injurious stimuli and are necessary to convey such information from the periphery to the central nervous system. Crustaceans, such as shore crabs, are widely used in science and aquaculture. Understanding whether they can experience pain is essential for improving their welfare. One key criterion for assessing pain is the presence of nociceptors. In a new study, scientists from the University of Gothenburg, the...

Castillo-Rogez et al. show that there likely is an ocean layer in four of Uranus’ major moons: Ariel, Umbriel, Titania, and Oberon; salty -- or briny -- oceans lie under the ice and atop layers of water-rich rock and dry rock; Miranda is too small to retain enough heat for an ocean layer.

Life reconstruction of Ninumbeehan dookoodukah in a palaeoenvironment reconstruction depicting its life and burrowing across seasons: (left) Ninumbeehan dookoodukah is resting on the edge of a river with a low water table as the wet season ends; (center) a small community of Ninumbeehan dookoodukah are in their estivation burrows at the apex of the arid season; (right) the onset of the humid season brings rain, triggering a mass emergence of Ninumbeehan dookoodukah from their estivation burrows. Some individuals expire before the incoming rains, leaving them to be preserved as fossils. Image credit: Gabriel N. Ugueto.

This Hubble image shows NGC 2090, a spiral galaxy some 40 million light-years away in the southern constellation of Columba. The color image was made from separate exposures taken in the ultraviolet, visible and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). It is based on data obtained through six filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.
