Wallace Marshall (UCSF): Ten Craziest Things Cells Do

Рет қаралды 192,052

Күн бұрын

www.ibiology.org/cell-biology...
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.

I showed this to my 6 year old son and he loved this video so much! I was watching my son as he was listening to you, it was the cutest thing - he would pause the video at times to understand/define any word he didn't understand. Sometimes he took notes, but most of the time he would draw the definition and color it! He was doing this for 4 hours. You are an excellent teacher and very easy to listen too. My son subscribed to you. Thank you :)

Good for you for Allowing your son to watch an intelligent video, if it kept him entertained for 4 hours he understood enough not to be bored by something that was incomprehensible to him. Ignore any knocker who suggests otherwise. It’s incredible that he drew some of the pictures. Encourage his interest. Don’t dumb the child down to the level of people who would suggest that he doesn’t understand at least enough to hold his interest for 4 hours. As an adult with no background in biology, I don’t understand all of it and, like your son I frequently need to stop look up the meaning of a word. Even then I know I don’t fully understand the subject matter of the video however, my general knowledge has been increased by viewing the lecture. Early exposure to topics is excellent for children’s learning. Young children don’t know that they’re supposed to be “grown up” before they understand the world around them and so incorporate what they experience into their general learning . Good for you. Allow him watch whatever is good for him and stirs his interest. 🌲🌝☘️

beautiful composition! as a grad student in a computationally heavy neuroscience program, the comment about the limits of individual cellular computation hit home hard. It brings to mind current models for neural networks, simple perceptrons with simple error functions that are able to output solutions to protein folding and all kind of stuff! a seeming contradiction that models can produce complexity, but reality consists of something much more complex than a perceptron. super cool video!

A few years ago, in the gap between two jobs, I arrived at the conclusion that I knew almost nothing about unicellular organisms and had to penetrate the topic. After some two years I ended up having collected many thousands of photos of protists and algae of all different types, meticulously arranged in order of the newest cladistics to be found in the web. By the way, I got somewhat familiar not only with their evolutionary history but with plenty of incredible facts about their life cycles, cell structures, sizes, ways of metabolism, mobility, vision, etc., many of them fresh discoveries of science. There is an absolutely amazing microbiological universe everywhere around us and within us, hidden to our eyes and to the awareness of most. So complex that we are still at the beginning of its exploration. Thank you for propagating that knowledge, you brought in some great examples.

Thats's amazing. A critique I would like to make is: the computational step, for example, in solving the maze is porbably more in the diffusion and the density of the molecules than the cell then does follow to find the solution. What I mean is that the cell start with the maze already solved to some extent. One way to solve a maze is to simulate a "flooding" from the exit then when the water reach the entrance you just follow the "flow" or the height of the water in the opposite direction. The first step (simulating the flow, or the diffusion of the molecules) is computationally expensive, following the flow is computationally trivial. In the same way cells might simply follow the density of certain molecules and grow in that direction eventually reaching the exit. The same thing applies to the subway example where the problem is pre-solved simply by chemistry and diffusion of the molecules.

Tay100 , About as idiotic as your comment sounds. I watched a video that showed an evolutionary link bust made from a couple of teeth. Really? An entire head with primitive ape-like features from a few teeth? Are evolutionists that gullible? I know it and you know it that there is a on-going conspiracy to shut down the world-wide discoveries of ancient civilizations building stone structures and buildings that defy our modern abilities. Long before I became a believer on God, I was a pagan-catholic. I didn't accept evolution for lack of evidence. What I did see was clear evidence of grand-scale genetic engineering just as we do with domestic animals. Then came Chariots of the Gods and that was my answer with hard proofs. It was scoffed at, but that means fuel to my mind. The ancient accounts of Spanish explorers all pointed to 'sky gods' that came down to help primitive man move civilization along. Sky gods, you say, not just any old martian aliens, but gods. Hmmmmm... Interesting 🤔. Then I had an opportunity to study the bible with an amazing lady who knew it backwards and forwards. But I would use only the bible, nothing else. That didn't mean I came to the truth-hunt unarmed. I bought a bunch of different bibles to add to a few I inherited. I also bought a Hebrew/Greek - English interlinear translation of the old and new testaments. I spent two years studying all religions and comparing them to evidence. I bounced my new biblical ideas off friends, employees, and family (no internet at the time). I filled binders with bible studies of every topic. What I found changed my life for good. I found out about creation and the creator. I found out that all man-made religions are a lie. I still know that evolution is a farce. And my original suspicion of Carl Sagan's theoretical life and physics was 10% science and 90% snake-oil, has just expanded over the decades. Evolution and theoretical science teamed up in a board-room somewhere to develop their business model. Carl Sagan failed to create life, but he did open the door to us finding the miracle of life and the living cell. NOT what he intended. But the die had been cast, and the atheist connection was forged. The bible is more amazing than you could comprehend. God set it up that way so he could control it and who 'got it'. A back-drop of what's behind it would take a book, but why? I know the bible and people whom God chooses will learn the bible. That suits God, so it's good for me.

@flymasterA 4 жыл бұрын

Tay100 , BTW, I'm no idiot. I did't have the money or the backing to get into college, although I wanted to become an aerospace engineer. So I settled for a technical degree in industrial design. Within 6 years I was a design department head and within 10 years I started my own engineering business in the oil & gas refining industry. Tough/good times, feast/famine, no degrees, no post school training, hard work, etc., but I survived 30 years on my talents as the envy of my constituents by making more than any of them, but with their degrees. When I decided to start my business right in the middle of a bust, my fellows said I was crazy. Three years later I was making over 6 figures and never looked back (while they were still laid off). So when I am called a looney for believing in God the creator, 'been there- done that, got the t-shirt'. I'm used to it. I'm retired now, but I may re-start my hydrocarbon process school for plant operators. I can visualizing sitting there n a board room while listening to the evolutionists and theorists conspiring on how to increase their market shares.

My suggestion was based solely on the fact that cells are little chemical machines which often use the same or similar components with similar chemical structures. She said I was "crazy".
