Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ago, when viruses inserted their genetic material into our ancestors' ...

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 ...

You are the product of metamorphosis. During the third week of your embryonic existence, fateful genetic choices were made that began to transform a tiny ball of identical stem cells into a complex ...

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

A study published today in the journal Developmental Cell uncovers new insights into how the heart forms during the earliest stages of embryonic development. The research, led by scientists at the ...

Implantation, one of the most poorly understood phases of early human development, occurs in the depths of the womb, at a ...

Understanding how cells differentiate during early embryonic development is crucial for advancing regenerative medicine and developmental biology. Pluripotent stem cells (PSCs) have been invaluable ...

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 ...

Chimpanzee naive pluripotent stem cells (PSCs) can now be grown in cellular cultures, reveals a recent study. They successfully created chimpanzee early embryo models, called 'blastoids,' and found ...
