Hey I'm a (UK) high school student and I've not heard of this field before but (going by the name) it is exactly what I want to do! Can you give me any insights on how you got into the field/exactly what you do?
@@nicoka484 civil engineering (structural biomimetic), polymer engineering (creating polymer with biomimetic properties), biomedical engineering (biological related stuff). Basically engineering area 👍🏼 Best of luck.
@@nicoka484 No worry. You should ask around uni in the UK, read on their courses. I think he's doing PhD research degree but good to have an aim early on. Studied in Sheffield previously
"Imagine bandaging an intestine the way you would bandage a finger!" I... um... must I? I mean, I can honestly think of a lot of other things I'd rather imagine.
@@NEVIXIA dissolvable/absorbable stitches already exist. They are broken down then absorbed by the body. Same thing would apply here. From the source article in the description it says it's made out of a biorubber and sugar based glue, so when it dissolves the sugar is probably used by cells and the biorubber compounds likely get sent to the liver for further breakdown and disposal.
@@NEVIXIA Presumably the macrophages or some other immune cell that also has clean-up functions absorb it and break it down, or the red blood cells absorb it and dump it in the kidneys or liver for removal
wow! I wish my friend had waited a couple years to have his pituitary adenoma removed. He just might still be alive today. He was my science & nature buddy. And I really miss him.
That's the game of life right there. Adapt or die - every species has its own set of life/death problems and situations that they must adapt to. Over time, those that consistently survive develop some traits and behaviors that can be seen amongst most, if not all, of the survivors. Those that managed to survive managed to solve the problems that would have otherwise led to their deaths. Evolution is rigorous, and it's far from perfect. But it gives us a look into how certain species tackle their problems, and it is precisely by looking at these adaptive mechanisms that we're able to draw connections and morph their solutions to fit our own contexts. That's the premise of biomimicry, and it's truly fascinating stuff.
I've had endocarditis and they used a new scientific way back in 2008 to make a new mitral valve out of my paracardium I was the very first human to have this procedure done ever
One avenue to explore in improving the tissue extractor speed is to scale it down and use vibration harmonics to drive it rather than a direct mechanical force
That's precisely what it is. The importance of the surface contouring of a gecko's foot to its terrain isn't the physical distance between the materials, as the video seemed to imply, atleast the way it was worded. It's a matter of to what scale the material is able to contour itself to irregularities in the terrain surface. Like the Coastline Problem, where the length of an island's coastline can range from a thousand miles to a million miles, depending on what the size of the units of measurement you're using are. The forces at work are Van der Waal's forces, so if you've got a thousand times the surface area, it's not that the distance between the materials has been reduced by a thousand, it's that you've got a thousand times the number of contact points, and so a thousand times the number of particle interactions. Enough of them, and you can actually fight off gravity, if you only weigh an ounce (if a gecko were made out of mostly, say, lead, I don't know if it would fare so well). Addendum: Now that I think about it, since we're dealing with molecules, which really are a quantized system, and not a nonquantized mathematical model like if we were dealing with gravity, I'll bet that, theoretically, there really is a perfect contouring that you could achieve, where all contact points have been made, and there's no way to improve, at which point Van der Waal forces will've reached their limit. Still don't think they'll hold up a lead gecko, though. But I could be wrong.
Who else knows that #4 is the plot of a _The Odd Couple_ episode? (S4E13 according to IMDB) Only it was barnacles, not mussels. The downfall for dental applications? Cottonmouth.
Not necessarily. I mean, if we're talking a brain I'm inclined to opt for precision over speed; I'd rather have it take a little longer than have it trash its surroundings but finish faster...
skin grafts/ why not study angler fish where the males bite the females and their tissues merge. the female feeds and passes nutrients directly to the male.
Long ago in a movie(or maybe JUST MAYBE) an episode of the Odd Couple.( I seem to remember Tony Randall being the actor) Anyway they tried to sell a glue based on the stuff barnacles use. The mussel glue made me think of it.
@Christel Headington It was the Odd Couple. I remember the episode well. Oscar's dentist created a glue for oral use from barnacles. Unfortunately, it didn't hold in dry mouths!
@@christelheadington1136 The Odd Couple was one of the best series ever. Keep an eye out for the one with opera singer where Oscar has to take his place as Rigoletto. Hilarious! 🤣🤣🤣🤣🤣
I know that it is too late and no one would probably see this, but still I want to comment about the gecko feet thing. I think Band-Aids that are designed with the property of gecko feet would be really great for regular old bandage usage. I’m allergic to a lot of Band-Aid adhesives, but I don’t know which ones to avoid due to the cost of a allergy test. Here’s the thing, I’m lucky that my allergy is only a contact rash that develops in contact with the substance for duration of time, but it is really hard to keep cuts and scrapes clean in places where a rap would not do. If one of y’all people out there could develop the Band-Aid based on the gecko feet and market it then I will be willing to pay around three dollars more for a Band-Aid like this compared to the regular Band-Aid. It could also be a really good science fair project for a student who is enthusiastic about science. Just saying.
3:00 Serrations would increase the surface area and contact patch, therefore causing more irritation that if it weren’t. Right? I mean regardless, it’s not Significant enough to feel but various chemicals and cutting methods and geometry also make this task easier. The extreme difference in diameter between the proboscis and a flu shot needle is an insane amount also. Mosquitoes proboscis are made of six tendril type things, each with separate dedicated purposes like cutting, drinking, injecting numbing anti itch chemicals.
I've smashed many mosquitos that were sitting on me in my life, so I may have not gotten every single one of them, but I would like to think I've been winning the ratio. They are very noticeable for me. The entirety of them, not just their needle.
Hank, I realize you and I don't have the same condition even if we each have an affliction for the same organ. How the hell did you say "wrap around your intestine" without wincing? I did and I'm sitting here listening to you.
Not too surprising nature has us beat in a lot of little engineering tricks. We've been at this for a couple dozen millennia, nature's been at this for a couple billion years. Trial and error over that timescale leads to a lot of amazing things.
It's Murphy's Law: now they make a shot that doesn't hurt, but thinking about why it doesn't hurt gives you such a bad case of the willies that you pass out anyway
Phil Swift slaps flex tape to new mommy's tumtum... Yee-doggy! Just cut, peel, stick and seal! Imagine everything you can do with the power of Flex Tape!
Another thing in science that should really make you think, but some people just don't want to think about the philosophical implications of what is going on here. I'm glad these advancements are being made and I hope they continue to be made, because they are awesome and could help a lot of people... but here's the philosophy I'm getting at: this implies things that some people just don't want to admit. Us Christians have no problem with it, because it helps our worldview... but nonbelievers just hate it. So think about it for a little while, why don't you? That is all.
No that wouldn't work bc body requires continuous oxygenation. You breathe in 8 liters of air or 2 liters of oxygen per minute, every minute.. are you going to inject large quantities of oxygen rich chemicals into blood every single minute for days? Anyway we already have a compound in blood that absorbs oxygen - hemoglobin. Your lungs are very effective at what they do - that's why they put those persons in need on respirator to help them breathe
3:16 I have dermatographic urticaria which makes me instantly alert to mosquito bites. It doesn't save my the itchy bumps but I can tell within the microsecond they have stuck me. Edit: 3:54 Lay-brum.
They do! Radio waves are just a frequency of light, and lasers are just focused light. Making noises and communicating by, like, doing a thumbs-up? Light and sound waves, not that far off. As for lasers... Your eyes focus light onto your photoreceptor cells, effectively making tiny harmless lasers. And, chameleons and octopi can do the same, shifting how light is reflected, focusing or defocusing inside their cells to change colours.
Are any of these actually in use today? 9:38 - wrong sized (width-wise) bandage for an adult leg for starters, then, its not being applied properly anyhow. Great way to restrict blood flow and create pressure sores if it doesn't fall off first.
Buen video, según el tipo de picaduras de insecto, es los tipos de cosas que se le pueden hacer a la piel humana, así como tipos de agujas y hasta tipos de líquidos y sustancias que se pueden inyectar más fácilmente según el tipo de agujas indolora en los tipos de picaduras de insectos, esto también aplica a tipos de músculos, órganos y hasta cartílagos y tendones para aplicar en estos últimos cas9 crispr, sobretodo si es biocompayibles de roedores y lagomorfos piezas como cartílagos y tendones, sobretodo rodillas y artículaciones de poco acceso y pocas venas, poder regresar la movilidad si la rodilla estaba mal o gastada, sugerencia, los médicos saben o sabrán más del tema.
Las garrapatas contienen válvulas y hasta ingeniería hidráulica pero especializada en sangre animal, sus aplicaciones irían hasta poder disolver y extraer sangre de varias situaciones, desde pus, coágulos, sangre podrida, y hasta partes delicadas de cuerpos humanos y hasta veterinaria que también adaptarse de cosas de medicina humana a otros animales, sugerencia y obvservaciones.
well i guess i chose the wrong video to watch while having my lunch, scishow keep showing something disgusting, still interesting to know how the tech is on going and by the way, the techs inspired shown here are still under development which i thought already been in use for at least a decade 🤔
