Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before ...

An international study has identified a gene that plays an important role in the development of the human embryo. If it is altered, malformations of various organ systems can result. The gene emerged ...

A small tissue fold in fly embryos, once thought purposeless, plays a vital role in stabilizing tissues. Researchers show that it absorbs stress during early development, and its position and timing ...

Images of the multicellular development of the ichthyosporean Chromosphaera perkinsii, a close cousin of animals. In red, the membranes and in blue the nuclei with their DNA. The image was obtained ...

A single-celled creature originally found in shallow sea sediments around Hawaii develops into multicellular structures with remarkable similarities to animal embryos. The finding could help ...

A fossilized dinosaur embryo discovered inside a fossilized egg in southern China is reshaping scientific understanding of avian evolution. Preserved for more than 70 million years and left unexamined ...
