An unusually elastic protein has been discovered in one of the most ancient groups of animals, the over 600-million-year-old cnidarians. The protein is a part of the "weapons system" that the ...

The animal kingdom contains a vast array of animals capability of remarkable regenerative abilities, but known are quite as adept at this healing task than sea-swelling Cnidarians, such as hydra, ...

A new study into the neurons found in the earliest-diverging animal lineages reveals key clues about the form of the most ancestral nervous system, and how neurons first evolved. Neurons, the ...

Corals are keystone species for reef and marine ecosystems but coral bleaching due to climate change and ocean warming is killing them. A new open access study by researchers at the University of ...

Neurons, the specialized cells of the nervous system, are possibly the most complicated cell type ever to have evolved. In humans, these cells are capable of processing and transmitting vast sums of ...

Studying corals usually requires either observing them alive in the ocean or examining their dead tissue in a laboratory. But new research offers a way to keep all coral cell types alive in a lab ...
