Wallace Marshall (UCSF): Ten Craziest Things Cells Do


Dr. Marshall refutes the commonly held idea that cells are just bags of watery enzymes. He runs through his “Top 10 List” of unexpected and amazing things that individual cells can do. These including growing to be huge, navigating mazes, and performing feats that seem to belong in science fiction.

Speaker Biography:
Dr. Wallace Marshall is a Professor of Biochemistry and Biophysics at the University of California, San Francisco. He is also a Director of the Physiology Summer Course at the Marine Biological Laboratory in Woods Hole. Marshall’s lab is interested in how single cells count and measure to determine cell size, number and organization. They have developed the single celled giant ciliate Stentor coeruleus as a molecular and genomic model organism for these studies.

  1. Carl Sagan is an example if ignorance setting policy. Even the expanded knowledge of the cell cannot undo the atheist mindset he helped build. And there's still 10,000 times what they know yet to learn. And that's not taking into account 'why', which they choose to remain ignorant.

  2. Why do people say toxoplasma is harmless all the time.
    Just because, of the half of the human population effected, only a handful of people actually die from it, doesn't mean we should let a threat that can cause delirium run wild on us…right?

  3. The Creator Yahweh Elohim is intelligence wisdom and knowledge doesn't have it is it an everything that is created is created in genius and is intelligent man relies on intellect and it is a stupid servant to the heart you can't get anywhere like that you have to look at it just the way it is and then it unfolds to be intelligent beautiful deserves honor the Creator deserves our honor and always honor him and his Divine name Yahweh Elohim yahshua thank you so much for this information Romans 1 19 and 20 take the natural the things you can see to understand the spiritual the things you cannot see this is intelligent

  4. the more I learn about microbiology the less im convinced that evolution can explain it. Take the "kinetochore" https://youtu.be/fpHaxzroYxg?t=857 or "helicase," https://youtu.be/fpHaxzroYxg?t=519 how can such complex micro-machinary be explained in terms of trail and error, all these bits fit together and work like a complex assembly factory, if one "evolved" or developed more complex shapes / behavior over time the entire system would need to evolve at the same time to adapt. How does Darwinism explain the complex, seemingly, intelligent world of cellular machinery?

  5. Dr. Marshall: "There's nothing more extreme that you can do than to explode."
    Me: "Haha that's funny."
    Dr. Marshall explains how rice blast fungus blow up plant cells walls
    Me: "Oh, well, that is REALLY EXTREME indeed."

  6. Are humans a natural part of the Toxoplasmosis life cycle and if so, how do the affected behaviours in the human host help it get back into cats? Is risky behaviour replicated in cats to make them bite and so pass on Toxoplasmosis? Do cats care more or less about their grooming?

  7. Things like this back my theory that the consciousness we perceive is just an extension of cell consciousness. Example- As he shows in this video. When you are cut, you are not hurt, your cells are hurt. They then communicate this information to their fellow cells and to the brain to initiate the healing process. You don't grab and coddle the wound because your brain is hurt, you coddle the wound because the cells are hurt.
    Further more, as explained above, cells can move, eat, reproduce, excrete waste, and can problem solve. Along with communicating to fellow cells. They work together for mutual benefits of nutrients, protection, communication, problem solving, and reproduction.
    Our brain is just a communication hub for the cells. Our lives exist in service to these cells. If they are hungry, we are hungry and search for food. If the cells tell us some thing is hot through proteins they have (Trpv1), we then avoid the heat or go towards it if its not too much heat. Our cells give us our perception of the world. Put together by our brain, so that the community of cells can work together to move about the world and search for food.
    Did we solve the traveling sales man problem? Or did our cells solve it, and we just solve it through the collective knowledge they give us? Memories are just the brain cells storing information about the world to better serve the community of cells.
    People work much the same way. If one human is hurt (The cell), we communicate to other cells (Emt's) to come heal us. We communicate ideas to other cells, about problem solving through ever more complex systems. First letters, then phone calls, then emails, and now one human can communicate instantly with another human on the other side of the world. We humans all work together for the same things as cells. Nutrients, protection, communication, problem solving, and reproduction. We even have a reward system for cells that do their job for the community. Its called money, and it allows that cell to gain more nutrients and protection etc.
    We are a community of cells (humans) built out of another community of cells. All working together for nutrients, protection, and reproduction. All to fight the decaying wave of entropy started by the big bang. As entropy as increased in the universe, so too has these closed systems fighting against decay.

  8. Love this talk ~ so fascinating and well presented

    Each section is full in scope strangeness and diverse complexity
    Thank you Dr. Marshall

  9. Cells responding to electric fields: That is how bone remodeling works. The crystalline structure of calcium hydroxyapatite (the hard stuff in bone), because it is highly ordered, produces piezo electric charges when compressed. The bone forming (osteoblasts), and bone removing (osteoclasts) respond to the electric field, and lay down bone on the compressed side, and remove bone on the elongated side.

  10. Great presentation
    Maybe cover Exosomes?
    Exosomes are extra cellular vesicles a virus-like particles made up of an outer lipoprotein shell enclosing viral RNA fragments.
    They act as molecular programs that can change the functions within a cell.

  11. Complex; variety, growth, size very big or very small, can walk , mouth , eat, poke , crawl, attack, change direction, make decisions, interconnectivity, share parts, use components from other cells , micrpolast – a fragment will break off and function, can sense electric fields,

  12. Cell doesnt have just a complex system but a "miracle blowing mind complex organism" , No one think cells are boring anymore since the discovery of the "DNA"

  13. Excellent! For years i have been gathering what i call "Remarkable Facts About Life." Right now it stands at 84 pages long. Now i have ten more to add!! Thanks for this. I was waiting for you to discuss the bdellovibrio. Perhaps you should do "Another ten things cells do."

  14. Beautiful! What this really refutes, is the theory of evolution. The further we study, the more complex it gets, and there is no end in sight! The book, "Darwin's Black Box" was aptly named. Only an infinitely intelligent and powerful Creator could possibly bring about the cell. The statistical probability that any of the functions of the cell could have been developed by random processes is multiple orders of magnitude beyond impossible. To get from goop to a cell, is as likely as from a cell to a man. Seriously–if you had a sea full of random carbon/oxygen/hydrogen mix, how would you ever develop the eye, or microtubules, or exploding fungi weapons, or dyneins…or…

  15. solves mazes. Solves mazes!!!! I love this. This and quorum sensing in bacteria and parity violation and all the good stuff means if this kind of lecture is reality, I’m choosing this side of the mirror

  16. Maybe the 'personality' traits ('caused' by toxoplasmosis) predisposes to choosing cats as pets, without really changing human behaviour as such. And THEN the infection by toxoplasmosis happens. 🤷🏻

  17. No No No No No, cells don't solve NP-complete problems. This entire section is misleading and wrong. They may solve some _instances_, but it's not as though they're any better at it than human-created algorithms running on computers. If cells could solve NP-complete problems, then you could use a slime mold to make as many bitcoins as you want, or break encryption.
