The embryos of many species can stop developing when starved of nutrients, only to restart the process once these are restored – and scientists may have figured out how they do it. In the early stages ...

An international team of paleontologists has uncovered the oldest known fossil reptile embryos, dating back approximately 280 ...

The last 40 years have witnessed a deep transformation in our views of animal development. From seeing development a multicellular black box where over time a mass of cells acquires shape to form ...

The chemical reactions that cells use to power themselves provide key signals for one of the earliest and most critical steps of an embryo’s development. The findings bolster growing evidence that ...

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 ...

A cluster of fossilized dinosaur eggs discovered nearly five decades ago has revealed new secrets after being scanned with a stadium-sized particle accelerator. The high-resolution imaging allowed ...

Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...

The annual killifish lives in regions with extreme drought. A research group at the University of Basel now reports in “Science” that the early embryogenesis of killifish diverges from that of other ...

Nearly half the embryos studied underwent developmental arrest because of genetic mishaps in early development—a revealing insight that suggests more IVF babies could come to term with changes in the ...

Add Yahoo as a preferred source to see more of our stories on Google. As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of species over the course of ...
