Because when they added extra thyroid hormone to zebrafish's tanks, their tiny hearts were no longer able to regenerate.

因为当他们向斑马鱼鱼入额外的甲状腺激素时，斑马鱼的小心脏便不能再生了。

These are zebrafish embryos  each less than one millimeter long.

这些斑马鱼胚胎每个长度都不到一毫米。

It’s called FreemoVR, and it’s for mice, zebrafish, and flies.

它叫做 FreemoVR，适用于老鼠、斑马鱼和苍蝇。

Other groups are facing down the zebrafish, a relatively tractable vertebrate.

其他小组正在面对斑马鱼，一种相对容易驯服的脊椎动物。

But now, scientists have tried to build custom holodecks for fruit flies, zebrafish, and mice.

但现在，科家们已经尝试为果蝇、斑马鱼和老鼠建造定制的全息甲板。

Swimming along with them is a robot lure, the same size and shape as a zebrafish.

与它们一起游泳的是机器人诱饵，其大小和形状与斑马鱼相同。

In Switzerland, a small school of zebrafish swim around a circular path, with a camera overhead tracking their position.

在瑞士，一小群斑马鱼绕着圆形路径游动，头顶上的摄像头跟踪它们的位置。

In one line of experiments, researchers analyzed some 92,000 zebrafish cells, and gathered data from 7 different embryo stages.

在一系列实验，研究人员分析了大约 92,000 个斑马鱼细胞，并收集了来自 7 个不同胚胎阶段的数据。

Submissions this year included water droplets evaporating from the wings of a butterfly, A cell in the spinal cord of a zebra fish and other beautiful scientific imagery.

今年的参赛包括了水滴在蝴蝶翅膀上蒸发过程的录像，斑马鱼脊髓的细胞以及其他美丽的科图像。

And zebrafish often swim in groups, so the researchers used a special bowl and projected a bunch of space invaders -- like the video game!

斑马鱼经常成群结队地游泳，所以研究人员使用了一个特殊的碗， 投射出一群太空入侵者——就像电子游戏一样！

In the second experiment, the bees' behavior was observed and then transmitted to the fish robot, affecting which way it lured the school of zebrafish.

在第二个实验，蜜蜂的行为被观察到，然后被传送到捕鱼机器人，影响它以何种方式引诱斑马鱼群。

To further explore this relationship, researchers used robots to mediate between two species unlikely to ever encounter each other in the wild: zebrafish and honey bees.

为了进一步探索这种关系，研究人员使用机器人在两种不太可能在野外相遇的物种之间进行调解：斑马鱼和蜜蜂。

Thus, they could trace each zebrafish cell's fate through time to see how a single cell gave rise to a variety of specialized cells, such as heart, nerves, and skin.

因此，他们可以通过时间追踪每个斑马鱼细胞的命运，以了解单个细胞如何产生各种特殊细胞，如心脏、神经和皮肤。

But researchers observed some zebrafish cells switched to different new types – as indicated by the change in what genes were active—after they should have been well committed to a certain fate.

但研究人员观察到，一些斑马鱼细胞在本应很好地适应某种命运之后，转变为不同的新类型——正如活跃基因的变化所表明的那样。

The reason that finding might matter to us, is that recent studies in mice and zebra fish have shown that hearts with more diploid cells—like a zebra fish's—are able to regenerate and heal themselves.

这一发现可能对我们很重要的原因是，最近对小鼠和斑马鱼的研究表明， 具有更多二倍体细胞的心脏（如斑马鱼的心脏）能够再生和自我修复。

And a swish finish finish translating it I'm sure there's someone at UNM who can do that You do know I'm trying to start a legal practice right since been working on the effects of electromagnetic fields on zebrafish and Oh!

嗖嗖嗖地完成翻译，我敢肯定 UNM 有人可以做到这一点，你知道，自从一直在研究电磁场对斑马鱼的影响以来，我正在尝试开始法律实践，哦！
