So we can't quite make objects invisible, but what about super waterproof, or superhydrophobic, materials?

我们还不能完全让物体隐形，超级防水材料，或者超疏水材料听上去如何？

I coated this glass with a hydrophobic coating that does just that.

我用给这个玻璃加了有那个功能疏水涂层。

Their shared reaction to water makes the lipids stick loosely together—this is called the hydrophobic effect.

头尾对水让脂质分子松散地附着在一起，这就疏水效。

The tail is hydrophobic, which means it repels water and instead attaches itself to oils or fats.

尾巴疏水，这就意味着它可以排斥水分子，而附着在油脂上。

So you should be asking yourself, how can they be transported in the blood, when they're so hydrophobic?

所以你该问问自己，它们如此疏水，怎能在血液中运输呢？

Experts suspect the surfaces may be covered with some kind of hydrophobic material that repels water molecules.

专家揣测其表面可能覆盖有排斥水分子疏水材料。

This makes the hydrophobic effect disappear, and gives the molecules room to move around.

这会让疏水效消失，并提供了让分子移动空间。

Here's what they saw. The leaves are extremely hydrophobic, meaning water beads up to minimize contact with the surface.

以们观察到情况。叶片极其疏水，这意味着上面水会形成水珠，尽量减少与叶面接触。

When you surround a coronavirus with water, the hydrophobic effect gives the bonds within the membrane their strength.

当你用水裹住新冠病毒时，它疏水效会让膜内结构更坚不可摧。

Their tails, which are similarly repulsed by water, compete for space with the lipids that make up the virus's shell.

它们疏水尾部会与构成病毒外壳脂质争夺空间。

If that angle's more than 150 degrees, then it's superhydrophobic.

如果那个角度超过150度，那该表面就超疏水。

But most of what makes water roll off a duck's back are these superhydrophobic microstructures.

但让水珠从鸭背滑落主要因素，正这些超疏水微观结构。

The pepper extract sample goes into a column that's packed with hydrophobic particles that attract capsaicin.

辣椒提取物样本进入了一根装满疏水颗粒柱子，这些颗粒会吸引辣椒素。

But if that hydrophobic region helps human insulin bind to our cell receptors, how would this insulin manage it?

但如果那个疏水区域有助于人类胰岛素与细胞受体结合，这种胰岛素如何做到呢？

It can't make it through this hydrophobic region so it's going to dock with the G-protein on the outside.

它无法穿越这个疏水区域，因此会在外部与G蛋白结合。

Put those things together, that can help you live to 100. Well, if you're acrophobic or hydrophobic, this pool ain't for you.

把这些东西放在一起， 可以帮助你活到 100 岁。好吧，如果你有恐高症或疏水症， 这个游泳池不适合你。

This proved to be 40% less than that experienced over the same period by a standard super hydrophobic surface which they used as a control.

这证明比在同一时期使用标准超疏水表面减少了40%。

These alpha helixes and beta pleated sheets then are going to fold on top of each other where we have hydrophobic regions moving to the inside.

然后，这些 α 螺旋和 β 折叠片会相互折叠，疏水区域会向内移动。

Lotus leaves repel water because they are covered with minuscule waxy nodules that stop water molecules bonding with a leaf's surface tissues, meaning those molecules bond with each other instead.

荷叶疏水，因为它们表面覆盖着微小蜡质结节，会阻止水分子与叶面组织结合，因而水分子只能彼此结合。

And so the drop just pulls itself into this round shape and we get a really large superhydrophobic contact angle and that water just ends up rolling right off.

因此，水滴会自行收缩成圆形，形成极大超疏水接触角，最终水滴会直接滚落。
