    Thank you for posting this interesting topic. I always wondered how cells (white, sperm, neurons, and general tissue) did that. I thought receptors might have something to do with it, but you've now confirmed it. Thank you for being concise and passionate about what you love doing, Dr. Dyer, it shows. Cell biology is such an interesting field; so much that goes on in a cell, never mind with other types of cells! The complexity is exciting. I'll definitely watch more videos in this channel.

    She must be an amazing teacher, her explaining skills are awesome.

    Very interesting topic. Jayme did a very good job explaining the cells motion.

    Excellent delivery and explanation from Jayme. Thanks

    Watching the neutraphil(?) giving chase to the bacteria made me wonder how body justifies spending so much energy (moving the whole neutraphil) just to eliminate one small target.

    I'm a biochemistry graduate. I want to say how awesome this video is! Great job! I was not able to get in depth with cell motility during my undergraduate. Now searching for my graduate thesis to study in oncology. I'm interested in motility of angiogenesis and how the tumor cell secretes VEGF to create new blood vessels.

    How many polarity patches are there in a yeast cell? If there are very limited number of polarity patches (or just one), and if they are located in a portion of the plasma membrane that is not close to pheromones, then how does this polarity patch move? Because we know that vesicle trafficking occurs substantially only in regions where yeast receives a lot of pheromone signal, and without vesicles, polarity patch does not move much. Or does it?

    Interesting article and good presentation – thanks for sharing this!

    Fantastic video! Very easy to understand.

    But then how does the cell know how to physically move its body in such a way that it propels itself forward? And how is it being attracted to those chemicals being released by the egg? What makes it attracted to those chemicals? And how is it receiving those chemicals? Like how is it smelling? Because unlike us, they don't have olfactory receptor cells. And then whats generating a nerve impulse that would travel to a brain which it does not even have?

    your quite an interesting teacher

    This is great. I really love this channel. She's explaining complex biological behavior and research in very simple terms to make general public understand. I've always wondered how cells are able to know where to move.

    I think there should be difference between MSD in uniform pheromone and gradient pheromone. For bias random walk, the mean free distance in different concentration of attractant should be different, which is associated to the diffusive coefficient. The MSD only reaches about microns after 20 minutes. The polarity patch nearly stay in the original position. It is due to the ultra-small diffusive constant that hides the difference.

    Don't know what to say, except amazing. For someone who just wants to know about cells and life, this is magic. The extent of research to pin it down is just supreme.

    She starts as a cell biologist 0:20 and evolving into a geneticist 15:20 in just a record 15 minutes. How many time do we need to wait until she finds out herself as an inorganic chemist?

    Great explanation! Thanks!

    Where my cells at? From the front to back. . . well is u feelin' that?

    BTW I love her and her video. She's the paradigm of what education and information transfer should be. <3

    Always a fascinating subject. Having viewed ‘the secret life of the cell’ many times and been in awe of the response of the cell to the adenovirus, watch bacteriophages in action, semi grasped the implications of “how cells talk to each other”, how different motor proteins work in different places and the wonder at the connection, complementarity and competition between the world of virus, bacteria and single and unicellular life, my next question is …..given the obvious interconnection between all life (and non life -maybe, e.g. a virus), where, what, is the source of the directive information that enables all of this to occur. I look forward to the next exciting episode. Well done Jayme, fascinating, well presented and I love the passion and the excitement. Cheers. GT

    Would the sperm have better success in the area with less emitting to penetrate the wall of the egg that’s thinner sounds like it would be more accessible and if it knew this could that be considered a form of intelligence ?

    About a zillion hours of painstaking research compressed into a half hour lecture. Great job.

    I'm still curious about the mechanism of directional motion in cells with flagella or cilia.
