The creation of a woolly-mouse embryo marks a significant leap in the field of de-extinction, bringing us one step closer to reviving the iconic woolly mammoth. By combining advanced gene-editing ...

In a world first, embryos have been sent to space so that scientists can study how zero-gravity affects a growing fetus. The mouse embryos were sent to the International Space Station to be raised by ...

A stretch of DNA in the mouse genome left by ancient viral infections is crucial for early development in the womb, new research shows. According to the study, published in December in the journal ...

It’s challenging to sustain a pregnancy when food is short, or conditions are otherwise tough. That’s why many mammalian embryos can postpone their growth to get through periods of environmental ...

Conditional genetics and single-embryo RNA-seq show that SETDB1 extinguishes the transient, retroelement-driven transcriptional programs of the totipotent two-cell state to facilitate the exit from ...
