DLR's MAPHEUS 9 sounding rocket carried four experiments into microgravity for approximately six minutes on 29 January 2022. The 1.7-tonne rocket lifted off from the Esrange Space Center in northern ...

New and comprehensive molecular research confirms a deep evolutionary division among animals. This new tree of life divides all so-called "lower" metazoans (Placozoa, corals, sponges, and jellyfish) ...

Pioneering research has given a fascinating fresh insight into how animal nervous systems evolved from simple structures to become the complex network transmitting signals between different parts of ...

The animal kingdom has gained a cousin and lost a mother. In a fundamental reconfiguration of the tree of life, scientists now say that the last common animal ancestor is not — as was commonly ...

Voigt, O., Collins, Allen Gilbert, Pearse, V. B., Pearse, J. S., Hadrys, H., and Schierwater, B. 2004. "Placozoa no longer a phylum of one." Current Biology, 14 R944 ...

The simplest of all known non-parasitic multicellular animals, Placozoans are small, flat, three-layered organisms roughly one millimeter in diameter. They contain just four types of cells as well as ...

A new and comprehensive analysis confirms that the evolutionary relationships among animals are not as simple as previously thought. The traditional idea that animal evolution has followed a ...

Dickinsonia was a strange, segmented organism that lived during the Ediacaran period, some 550 million years ago. But just what kind of lifeform it was has been a mystery: was it an animal, a fungus, ...
