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 ...

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 ...

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 use a light-activated protein to illuminate when embryos can cope with disruptions to cell division.Cell division ...

Naturally occurring haploids are predominantly documented in plants; the first report dates to 1923, when haploid individuals were identified in the Jimson Weed. Haploidy also occurs in certain animal ...

New research describes how nerve cells and muscle cells communicate through electrical signals during development -- a phenomenon known as bioelectricity. The communication, which takes place via ...
