The First 24 Hours of an Embryo

Wired Magazine writes:

For the first time, it is possible to actually watch the initial 24 hours of the life of an embryo at the cellular level.

With a newly developed microscope that uses a sheet of light to scan a living organism from many different dimensions, scientists were able to track the complex cellular organization of a zebrafish embryo as it grows from a single cell to 20,000 cells.

"Imagine following all inhabitants of a town over the course of one day using a telescope in space," Philipp Keller of the European Molecular Biology Laboratory in Heidelberg, Germany, said in a press release.

"This comes close to tracking the 10 thousands of cells that make up a vertebrate embryo."

It may only be a fish, but it is pretty awesome. Watch it below. Be sure to set it to full screen mode.
