This Pulsating Slime Mold Comes in Peace (ft. It’s Okay to Be Smart) | Deep Look

On these rotting tree trunks, something is
alive. They can stand upright and produce spores.
But they’re not fungi or plants. When they’re hungry, they spread across the forest, chasing food. But they’re not animals. They’re slime molds. A slime mold exists at the boundary between liquid and solid. Each one is like one big cell. And it moves in a very strange way.
See how it pulses? A little bit forward, a little bit back, spreading and searching for bacteria or fungi to eat. But hold on! Today we have someone else who
moves in strange ways: the host of “It’s Okay To Be Smart,” Joe Hanson. AMY: Oh hello Joe. JOE HANSON: Hey there! So from down here,
it’s pretty obvious that slime molds don’t have legs or any appendages. They move just
by changing their shape. AMY: Scientists want to know how this works.
So they brought a type of slime mold into the lab and fed it some oats. At the University of California in San Diego,
they put a piece of slime mold under a microscope, watched its weird, pulsating movement up close. JOE: That motion is triggered by chemicals
moving around inside it. AMY: Water, moving in waves, carries tiny
calcium molecules from back to front and back again. The molecules are too small to see.
They’re not those circles — those are the slime molds’ many nuclei, among other stuff.
But scientists can track the calcium flow. In this video, it appears in light blue. The
calcium triggers a reaction that makes the cell wall contract. JOE: The slime mold squeezes itself, almost like a water balloon. AMY: That contracting-and-sloshing helps the slime mold inch forward, bit by bit. And it kinda begs the question, could we build something that moves that way? I mean, usually, we think of robots as solid, hard-edged machines that roll or walk from one place to another. But what if they were fluid and powered by chemical reactions? Like this Japanese “walking gel.” Maybe this is a really early step toward some hypothetical robotic goo that could squeeze into the narrowest parts of
your body. Hey Joe, imagine one of these inching through your arteries, helping clean them
out as it goes. JOE: Uuuh. That might be kind of… creepy. JOE: Hey Amy, I think I have a slime mold
story even weirder than yours. AMY: Oh yeah? Try me. JOE: Well, over on my channel we’re going
to look at some slime molds that actually help each other. They’re even kind of smart. AMY: What? That’s nuts. I’ll be right
over. JOE: Thanks for having me on Deep Look, Amy. And everybody, you should definitely subscribe.

  1. Okay, I find this genius interesting, but I noticed something so beware

    Who else thought they kinda looked like the pulsing stuff at the start of "The last of us"

  2. How does this snot come in peace? You didn't explain that or how it dies or steal moisture from mushrooms and if it will steal it from our lungs or not

  3. O Lord….traveling snot!
    Seriously tho…not a bad idea about using it for human health, but what are the byproducts of it's waste? Hmm ..harmful or do we get healthy with a runny nose?

  4. I love watching videos of slime molds because they're about as close to alien as it gets. Makes me want to build a tank for it.

  5. I want some. With the right tweaking, in a controlled environment, perhaps accelerated growth could be possible and then … 🤔😈

    Muhuhuhahahahaaa! Mankind won't know what hit it. Muhuhu… muhuhahahahaaaa…. Aaaaahahahahahahahaaaaa!!!!🔬A lot of people are going to DIE!!! Aaaaahahahahaaaa hahaaaa hahaha!!! ☠

  6. fascinating. When I was a child a teacher told me that an ostrich egg yolk cannot be only one cell because it's too big.

  7. Pretty sure those are alien parts that escaped from Area 51 waiting for the opportunity to find other parts to form its whole body

  8. God has indicated such miracles of His creation in Chapter 2 of Verse 26…. "Indeed, Lord (Allah) is not ashamed to set forth an example (like) even (of) a mosquito and (even) something smaller than it. Then as for those who believed, [thus] they will know that it (is) the truth from their Lord. And as for those who disbelieved [thus] they will say what (did) intend Allah by this example? He lets go astray by it many and He guides by it many. And not He lets go astray by it except the defiantly disobedient."….. Such miracles are easy for God
