In a ground-breaking experiment, researchers have successfully created the first human-monkey chimera. The work, published in the journal Cell, describes the the first embryo containing both human and ...

Scientists have discovered a method of helping human stem cells thrive in an animal embryo—a key development in efforts to ...

The world is full of unusual unicellular organisms and microbes, many of which have not been discovered yet. In 2017, scientists identified a single-celled marine organism called Chromosphaera ...

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 ...

Scientists at EPFL have created a scalable 3D organoid model that captures key features of early limb development, revealing ...

Scientists have successfully grown embryos that contain a combination of human and monkey cells, a major breakthrough in a rapidly advancing field of genetics that researchers say could one day ...

In a paper in Science this week, Penn researchers report the first detailed molecular characterization of how every cell changes during animal embryonic development. The work, led by the laboratories ...

The first few days of a human embryo’s development, known as pre-implantation, are important. It’s when the first cells are formed, and these decide if the embryo can survive, how it will implant in ...

At this stage, known as gastrulation, a flat and featureless sheet of cells folds into a living blueprint for the body, a ...

Sarah Franklin is chair of sociology and director of the Reproductive Sociology Research Group at the University of Cambridge, UK. Studying the early development of humans and other mammals takes ...

Scientists have studied the nematode worm Caenorhabditis elegans for decades, making essential contributions to basic science. In the latest milestone, scientists used cutting-edge technology to ...
