Microscopic particles in the air can affect breathing and cause other problems.

And those massive amounts of particles can cause clouds to form.

排出粒便会形成云朵。

The particles in the air are a mix of solid and liquid droplets that get embedded into the lungs when we breathe.

空气粒是固体和液滴混合物，当我们呼吸时，它们会被吸入肺部。

Organic molecules could be the food for life, or they could be the product of life, or maybe they're from something all together different such as geology or meteorites that were deposited into the lake.

有机粒可以成为生命食物，也可能是生命产物，或者也许它们来自不同地方，比如沉积在湖地质或陨石。

They say we eat a credit card's worth of plastic every week with the microplastics.

据说我们每周吃掉塑粒相当于一张信用卡塑。

This photo records the amazing beauty of dust particles floating in the sunlight.

这张照片记录了在阳光漂浮尘埃粒惊人美。

Elements like oxygen and nitrogen, even countless dust particles, make up the air around us.

氧气、氮气，甚至数不尽尘埃粒，构成了我们身边空气。

Its guidance temporarily said there was evidence that when an infected person coughs, sneezes, talks, sings or breathes, infectious droplets and airborne particles could stay in the air and travel distances beyond six feet.

有证据表明当感染者咳嗽、打喷嚏、说话、唱歌或呼吸时，传染性飞沫和空气粒可能会停留在空气，且传播距离超过6英尺。

You can feel the little bits of food inside.

你会感到里面食物粒。

And so they create what we call microplastics.

然后，他们创造了我们所谓塑粒。

This makes the core a thick soup of ultra-hot subatomic particles.

这使得太阳核心变成一锅极热亚原子粒浓汤。

It was chemical engineer and material scientist Yendry Corrales-Urena who noticed the silica-based microparticles.

注意到这种硅基粒是化学工程师兼材科学家耶德利·科拉雷斯-包雷尼亚。

His team sequenced the DNA from bits of scroll dust.

他团队对卷轴上尘埃粒进行了DNA测序。

Trillions of these subatomic particles pass clean through your body every second.

每秒有上万亿颗这种亚原子粒穿过你身体。

Well, short-term exposure to the particulates from the forest fires is manageable, doctors tell me.

医生告诉我，短期接触森林大火产生粒是可控。

The tiny dust particles drill into the child's lungs.

沙尘粒进入了珍妮肺部。

The seven dust motes may come from interstellar space.

这七个星尘粒可能来自星际空间。

We found microplastics in the Arctic Sea ice, at the most remote stretches of islands in the Pacific and in the deepest ocean trenches.

我们发现，我们发现，北冰洋冰层塑粒出现在了太平洋最遥远岛上以及最深处海沟。

The highest-profile of these schemes has been part of a programme called SPICE (Stratospheric Particle Injection for Climate Engineering), which is paid for mainly by Britain's Engineering and Physical Sciences Research Council (EPSRC).

最受瞩目是简称SPICE（平流层注入反光粒气候工程）组织。SPICE主要是由EPSRC（英国工程与物理科学研究理事会）助资。

Number one, predators listen for people breathing, for animals breathing, and by covering our mouths and our noses, we prevented all these particulates from getting into the air, which then the animals can seek out.

第一，捕食者会倾听人呼吸，动物呼吸，通过捂住我们嘴和鼻子，我们阻止了动物可以寻找粒进入空气。
