Breakthrough in Cell Biology and Neuroscience in 2023

Study 1:

Researchers at harvard changed regions within mitochondria in humans and mouse cells. Mouse cells produce protein faster through mRNA translation than human cells while embryos develop at different speeds between species.

Study 2:

WIth a lot more going on than just ATP production, study suggests mitochondria's role in timing of nervous systems.They discovered Mitochondria is as pacemaker of speed of development in cells
