Mr. Sabanayagam studies the epigenome as it relates to microgravity.

Sabanayagam研究了微重力下的表组基组。

In microgravity, osteocytes aren't getting much loading stimuli, because less gravity means less weight.

在微重力下，骨细胞不会受到太多负荷刺激，为重力越小意味着体重越轻。

Up in space, you experience something called microgravity.

Hi， I'm Jack. Today's usage tip is to look at the sentence form of 主词加 suggest， ask， demand 加 that 动词 suggest， ask， demand 都含有建议、要求或是命令的意味 後面接 that 字句表示提议或要求的内容that 则可以省略喔另外，that 子句中的主词无论是单数或复数动词都一律用圆形动词也可以加上助动词should来强化所建议或要求的事情的语气来看个例句The museum asks every visitor be checked for prohibited items这间博物馆要求每位访客都要接受是否携带违禁品的检查。

From handling tiny amounts of liquid for biotech applications, to cleaning films that build up in water treatment, to moving liquids in microgravity on other planets, to even carrying molecules to make tiny robotic delivery systems.

从处理生物技术应用中的微量液体，到清理水处理中逐渐积累的膜，从在微重力的行星上移动液体，甚至到搬运分子来制造微型机器人输送系统。

Its value is not just in the fact that unique experiments can be conducted in microgravity, a sort of environment that's very difficult to replicate here on Earth, but it's also in the international collaboration.

它的价值不仅在于可以在微重力环境下进行独特的实验，这种环境很难在地球上复制，而且还在于国际作。

To better understand these changes, Kelly took part in a bunch of studies that tracked how his eyes, his bones, his heart and even his brain changed due to the microgravity environment.

为了更好地理解这些变化, 凯利参加了一系列的研究, 观察他的眼睛, 骨头, 心脏, 甚至大脑在微重力环境下的变化。

From handling tiny amounts of liquid for biotech applications, to cleaning films that build up in water treatment, to moving liquids in microgravity on other planets, or even carrying molecules to make tiny robotic delivery systems.

从生物技术中的微量液体处理，到水处理系统中的清洁薄膜，再到其他行星微重力环境下的液体移动，甚至是携带分子的微型机器人递送系统。

Space breeding refers to the process of exposing seeds to cosmic radiation and microgravity during a spaceflight mission to mutate seed genes and then send them back to Earth to generate new species.

太空育种是指在太空飞行任务中，将种子暴露在宇宙辐射和微重力下，种子基发生突变，然后将其送回地球产生新物种的过程。

In space, we're using it as a microgravity laboratory and science, that's becoming more and more valuable by the day as we realize what you can do in weightlessness.

在太空中，我们将其用作微重力实验室，随着我们意识到在失重状态下可以做什么，科学变得越来越有价值。

But this changes in space because of microgravity – the weaker gravitational pull making things in space float and seem weightless.

但由于微重力，这种情况在太空中发生了改变——微重力是指太空中的物体漂浮起来，看起来没有重量的较弱引力。
