Researchers have imaged every single cell in the body of a newborn mouse

Amazing stuff! 

"Researchers have imaged every single cell in the body of a newborn mouse, using a custom fluorescence microscope, high-speed cameras and an atlas of the mouse body onto which they mapped data. 

“Since Robert Hooke first described cells in 1665, more than 360 years have passed,” ... “Yet no one had directly visualized all cells in mammalian organs or in the whole body of a newborn mammal at single-cell resolution.” They also mapped responses to drug toxicity at a single-cell scale."
