Mitochondria Actin(g) Wavy

Mitochondria are known as the powerhouse of the cell because of their important function in producing energy. During cell division (also known as mitosis), a cell has to duplicate everything from its DNA to proteins to organelles - including mitochondria - and distribute them equally between two cells. However, no one really knows how exactly these mitochondria get distributed. In this episode, Dan and Derek discuss a new paper from researchers at the University of Pennsylvania and Janelia Research Campus where they find that a network of actin rotates around the cell like a ferris wheel during mitosis in order to distribute mitochondria equally. This discovery of how cells distribute mitochondria may have important implications for understanding and treating mitochondrial diseases.

Beyond the Abstract

Science and research for everyone

Hey science nerds! Welcome to Beyond the Abstract, a science podcast dedicated to discussion of the coolest cutting edge, basic science research papers in a way that just about anyone can understand. We're your hosts, Derek, Dan, and Ellen, three MD/PhD students coming from the University of Pennsylvania and Harvard Medical School who are passionate about science communication and bridging the gap between science and medicine.

In each episode, we’ll dive into a paper and talk about the experiments these scientists did, what it means for the future of research, and even potential impacts on human health and medicine. We've invited experts in these fields to help us understand and dissect these complicated but impactful papers.

We can't wait to share all this cool science with you.
