Similar materials are beginning to circulate again.

现在，这些相似的文件又开始流传开来了。

Today, our roads, sidewalks, bridges, and skyscrapers are made of a similar, though less durable, material called concrete.

今天，我们的道路、人行道、桥梁和摩天大楼都是由一种类似但不太耐用的材料制成的，这种材料叫做混凝土。

And because the architecture is similar material externally to internally, when the doors and windows are open you're not really sure where the building begins and ends.

因为建筑的外部和内部材料相似，当门窗打开时，你真的不知道建筑的起点和终点在哪里。

The provocation was that instead of growing a plant, like cotton, in a field over several months, we could use microbes to grow a similar cellulose material in a lab in a few days.

其发想在于，并不是花费几个月时间在地里栽培作物，比如棉花；而是只用几天时间，在实验室里用微生物培养出类似的纤维材料。

Atop that is the crust, which has some similar materials, but throws in more things like calcium, sodium, and potassium. If we made our own new planet, we'd probably want it to have similar elements and a similar structure.

最上面是地壳，它有一些类似的物质，但含有更多的东西，比如钙、钠和钾。如果我们创造自己的新星球，我们可能希望它具有相似的元素和相似的结构。

My own journey in biofabrication started with a project called " Biocouture." The provocation was that instead of growing a plant, like cotton, in a field over several months, we could use microbes to grow a similar cellulose material in a lab in a few days.

我自己的生物制造之旅始于一个名为“Biocouture”的项目。挑衅是，我们可以在几天内使用微生物在实验室中种植类似的纤维素材料，而不是在田间种植棉花等植物几个月。
