@@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.

it's kind of humbling to think that nature was able to devise solutions to so many of our problems before we even knew what those problems were!

[@r-i-v-v]

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.

[@gregorywhittaker1502]

I would have thought geckos feet would rely on Van der Waals forces for their attraction to surfaces

[@mikerich32]

They do, but Hank just didn't say it directly.

[@danacollins2625]

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.

[@Markle2k]

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.

[@eb9908]

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.

Do spray on or liquid Band-Aids cause an allergic reaction?

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'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.
