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 ...

Research shows how the curved shape of a zebrafish egg sets cell division timing, gene activation, and early cell fate ...

The first lineage decisions in mammalian embryonic development are made shortly after a wave of transcriptional activation that acts as a wake-up call for the sleeping embryonic genome to claim the ...

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 ...

The mystery of early embryonic communication is starting to be unraveled thanks to a new stem cell-based model.

Scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why ...

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 ...

Bioengineering researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a soft, thin, stretchable bioelectronic device that can be implanted into a ...

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 ...
