Scientists study ancient unicellular organism C. perkinsii to understand transition from single-cell to multicellular life. Research suggests C. perkinsii demonstrates early forms of multicellular ...

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 ...

Life on Earth may have developed the ability to form embryos even before it grew the very first animals. A single-celled organism that lives burrowed in the muck beneath shallow seas bears a startling ...

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 ...

After fertilization, embryos race through rapid cell divisions before slowing down to build specialized cells that will carry ...

New research is underway to decipher a fascinating biological puzzle—how some animals can naturally discard more than half of their genetic information during embryonic development. This radical ...

Long before calving, subtle biological signals can influence the health, growth, and future productivity of a calf.

An international study led by the medical Faculty of the University of Bonn has identified a gene that plays an important role in the development of the human embryo. If it is altered, malformations ...

A protein once thought to be of little consequence has been found to be a central player in processes ranging from male fertility to early embryonic development, according to a study published in the ...
