THIS is How You Grow a Backbone.

2013 Small World in Motion Competition - Honorable Mention

In this neat video clip above, Daniele Soroldoni of MRC National Institute for Medical Research in London, United Kingdom, showed us a gorgeous glimpse into segmentation - that's fancy biology speak for the division of the body (in this particular case, a vertebrate's body) into a series of repetitive segments like ribs and back bones.

Vertebrae segmentation is difficult to see because it happens during embryo development. But thanks to the transparent zebrafish embryo, Dr. Soroldoni managed to capture this pattern formation by using green and red fluorescent proteins. The details, as you can imagine, is quite complicated (Interested? Read on) - but suffice it to say that we all can appreciate the beauty of the process as captured in this wide-field microscopy.

Thanks Nicole Hall!
