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 is one case where science is on the side of life. The more we know, the more we see, the more undeniable life becomes.
