The Snail.

It's a double helix.

You look like a little snail.

What is a little snail?

And the snail's wired to a stick, so he's a little bit easier to set up the shot.

And that thing's going to swing around and smash the snail.

And they might actually be making use of fluid dynamics as a second force for breaking the snail.

That's why my nickname is Noah's Snail.

' Will you walk a little faster? said a whiting to a snail.

Female Voice

Try having a snail as a pet.

I ate snails, vultures, rabbits, snakes, and anything that had life.

I hope there aren't any snail rights activists around here.

And the snail's wired to a stick, so he's a little bit easier to set up the shot. And yeah.

Let them be like a snail which melts and passes away, like the stillborn child, who has not seen the sun.

As a snail which melteth, let every one of them pass away like the untimely birth of a woman, that they may not see the sun.

And so this guy gets the snail all set up and gives it a good whack.

And a few smashes later, the snail is broken open, and he's got a good dinner.

I'm going to show you the mantis shrimp approaching the snail.

So if this is the magenta side, if you unwound this helix right now it shows it in its wound state, but if I unwind this helix, one side would maybe be this magenta side of our helix and then one side is this green side, right?

This is a Dionaea, a Venus fly trap hunting snails sorry for the snail.

And then these bridges that you see in this drawing in the double helix, those are these connections right here.

Now, the other type of mantis shrimp is the smasher stomatopod, and these guys open up snails for a living.

You can see it coming in, and an incredible flash of light, and all this cavitation spreading over the surface of the snail.

Derived from Conus magus (Cone Snail), it is the synthetic form of an ω conotoxin peptide.

One point three million eggs per square meter inside the marine reserve where these snails are very abundant.

So this is a computer graphics representation of DNA, and I'm sure many of y'all have heard of the double helix.

Like on this topic, we have evidence that more than 13,000 years ago, humans in southern Greece were domesticating snails.

But the snail replied Too far, too far! and gave a look askance Said he thanked the whiting kindly, but he would not join the dance.

There's the aggregate and flagelliform silk glands which combine to make the sticky capture spiral of an orb web.

1862 Alexandre Emile Béguyer de Chancourtois publishes the telluric helix, an early, three dimensional version of the periodic table of the elements.

So the next and final question was, well, how much force does a mantis shrimp produce if they're able to break open snails?

Female Voice Squashing a snail may not seem important, but remember, even this choice will affect how Milo develops.

Chromosome lengths were estimated by multiplying the number of base pairs by 0.34 nanometers, the distance between base pairs in the DNA double helix.

The further off from England the nearer is to France Then turn not pale, beloved snail, but come and join the dance.

And actually, in the future, I do want to actually read with you Watson and Crick's paper on the double helix where they essentially talk about their discovery.

So almost 30 years before the double helix structure of DNA was elucidated, a single experiment involving fancy versions of household materials enabled deep insight into the basic architecture of the cell.

So the double helix just describes the structure, the shape that DNA takes, and it leads to all sorts of interesting repercussions in terms of how heredity takes place and how natural selection and variation might take place as well.

So this is a potent force in fluid systems, and just to sort of take it one step further, I'm going to show you the mantis shrimp approaching the snail.

Another resident of the Jalazone refugee camp was injured by IDF shooting during the incident. (Ha apos aretz, Jerusalem Post, 13 April 1994)

The most common form of transmission is by wading or swimming in lakes, ponds and other bodies of water containing the snails and the parasite.

That signal protein tells other proteins in the cell's nuclei to open up a part of the DNA double helix, the insulin gene, and start making insulin proteins.

And what happens is that as we turn increasingly to rules, rules and incentives may make things better in the short run, but they create a downward spiral that makes them worse in the long run.

And these animals may very well be making use of not only the force and the energy stored with that specialized spring, but the extremes of the fluid dynamics. And they might actually be making use of fluid dynamics as a second force for breaking the snail.
