Researchers have gained new insights into the mechanism behind the spatial organization of DNA within the cells of early embryos. When an embryo is first formed after fertilization, each cell has the ...

BEIJING -- Chinese researchers have developed an in vivo embryonic mouse intrauterine imaging technique, which has elucidated the dynamic process of brain development in embryonic mice in vivo, the ...

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 ...

Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ...

Embryonic development in roe deer is very similar to that of cattle but takes place in slow motion. “This allows us to better temporally resolve the sequence of events and find causal relationships.” ...

A new study from the MRC Laboratory of Medical Sciences (LMS) in London, UK reveals how ancient viral DNA once written off as ...

Genomic scientists have revealed new insights into the process of human embryonic development using large-scale, whole-genome sequencing of cells and tissues from adult humans. The study analyzes ...

Embryonic stem cells (ESCs or ES cells) are cells from the early embryonic development, from which all cells and organs of an individual descend. Embryonic stem cells are pluripotent, meaning that ...

The process behind embryonic diapause could explain how cancer cells can survive long periods of metabolic stress.

It would certainly spare mothers the hardships of pregnancy, but mammals do not grow in eggs. In a way, this is also impractical for science. While embryos of fish, amphibians or birds can be easily ...
