Today, in the 28th ScienceBeer, Rana was our Science Brewer. Rana is a PostDoc in Max Planck Institute of Molecular Cell Biology and Genetics and works on Cell Biology. Today we learned about the cell migration in retina. Do you know what happens to spawning Samlon fish? Rana told us that the very similar thing is happening to some neurons in our retina, but only during the construction phase of our eyes. And "us" here means all vertebrates! If you also want to know WHY those neurons migrate, and HOW they navigate their way, watch the video. Thank you Rana.
