How can we reliably and objectively characterize the speed and various stages of embryonic development? With the help of artificial intelligence! Researchers present an automated method. Animal ...

When the zygote, or the fertilised egg, starts to develop, the soon forming inner cell mass, a cluster of cells that will eventually develop into the individual, retains its pluripotent stem cell ...

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

Two to three weeks after conception, an embryo faces a critical point in its development. In the stage known as gastrulation, the transformation of embryonic cells into specialized cells begins. This ...

Animal embryos go through a series of characteristic developmental stages on their journey from a fertilized egg cell to a functional organism. This biological process is largely genetically ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

Over 130 mammal species can delay embryonic development, giving their offspring the best possible chance of survival in ideal ...

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 ...
