This video shows THG/SHG 4-D imaging of the zebrafish embryo cleavage stages. This video relates to an article that appeared in the Aug. 20, 2010, issue of Science, published by AAAS. The study, by Dr ...

How does a tiny cluster of cells become an embryo with a head, trunk, and tail? And how do thousands of genes coordinate this development? A new imaging method makes it possible to visualize the ...

Researchers confirm using zebrafish that if a certain gene is not excluded when vertebrate embryos are developing, the notochord will not elongate properly, resulting in a shortened form. Can a single ...

Striking new psychedelic videos give a glimpse into what living organisms look like during their earliest moments — and it took scientists years to capture. The videos are part of a new atlas of ...
