That's the light sensitive tissue at the back of the eye.

那是眼睛后部的组织。

Researchers looked at the role of specialized photosensitive cells in the retina.

研究者们研究视网膜内特别的细胞。

The last light a plant sees at night is in the far red of the spectrum, and this longer wavelength light inactivates a light-sensing molecule inside the plant, that isn't reactivated until the next morning.

植物在夜间看到的最后一束在谱中属于远红，而这种较长波长的会使植物内部的分子失活，直到第二早上它被击中时才会重新激活。

Since 2011, Tye, of the Salk Institute, has been using genetically-modified light-sensitive proteins to turn neurons on and off, and systematically tracing the connections between different parts of the brain involved in fear and anxiety.

自2011年以来，索尔克研究所的泰伊一直在使用基因改良的蛋白来开启和关闭神经元，并系统地追踪大脑中涉及恐惧和焦虑的不同部分之间的联系。

Finally, a general photosensitivity of the skin —essentially a catch-all category for other rashes that happen to sun-exposed areas —typically only lasting a couple of days.

最后，常见具有的皮肤损害，这包含了日照引的所有其它皮疹，通常只持续。

Whereas with a Japanese print, which uses highly light sensitive colourants, that can be displayed for more like eight months per decade, or even less.

然而日本的版画使用高的着色剂，每十年只能展览大概8个月左右，甚至更少。

For example, I grew up in the heat of Texas yet didn't have any problems with the photosensitizers in Lime or Celery.

例如，我在炎热的德克萨斯州长大，但对酸橙或芹菜中的剂没有任何问题。

They both have lenses that bend light and project an image onto a light-sensitive surface.

它们都具有能够弯曲线并将图像投射到表面上的透镜。

In other words, it usually has this red phytochrome confirmation.

换句话说，它通常具有这种红色的色素构象。

They've revealed that the molecules called phytochromes, now again you don't need to know that word because they've told you that they are a kind of molecule but again for future reference Phyto, P-H-Y-T-O means plant and chrome means colour.

他们指出，名为色素的分子——虽然你不需要记住这个词，因为他们已经说明这是一种分子——但为了今后参考，" " （Phyto）中的“Phyto”表示植物，“Chrome”表示颜色。

Nelson works as a guide and polar bear sentinel for some scientists focused on the sea ice and the other end of the food chain, the tiny light-sensitive organisms that live in the ice.

纳尔逊为一些专注于海冰和食物链另一端（生活在冰中的微小生物）的科学家担任向导和北极熊哨兵。

The idea behind the light sensitivity was that the memory formed by these cells could be reactivated by the light of a laser, causing the mouse to recall the memory.

背后的想法是，这些细胞形成的记忆可以被激重新激活，从而使老鼠回忆记忆。

This group of rare, genetic disorders, which involves the loss of light-sensitive cells in the retina, affects more than 2 million people worldwide, and can lead to complete blindness.

这组罕见的遗传疾病涉及视网膜中细胞的丧失，影响全世界超过 200 万人， 并可能导致完全失明。

If we clone this light-sensitive part of the algae and then add it to neurons through genetic modification, we can make neurons light-sensitive, too.

如果我们克隆藻类的这个部分，然后通过基因改造将它添加到神经元中，我们也可以使神经元对感。

The team made their discovery with a technique called optogenetics, which uses genetic engineering to introduce light-sensitive proteins into select brain cells.

研究团队使用一种称为遗传学的技术做出了这一发现，该技术通过基因工程将蛋白引入选定的脑细胞。

One way animals have evolved to see better is to have more of those light-sensitive cells in each eye.

动物为了看得更清楚而进化的一种方式是在每只眼睛中拥有更多的细胞。

The opsin gene for our green-sensitive visual pigment was duplicated, and the second version evolved to be more red-sensitive.

我们绿色感视色素的基因发生了复制，复制的第二个版本逐渐进化为对红色更加感。

As mentioned before, there are about 16 million of these tiny light-sensitive circuits in a camera's image sensor.

正如前面提到的，相机的图像传感器中有大约1600万个这样的微型电路。

This idea of genetically altered to have light sensitive proteins, I think that's a little bit too much detail up front, so let's move that down.

这种基因改变产生蛋白的想法, 我认为前面有点太详细了, 所以让我们把它移下来。

Why are there two times as many green color photocells in this pixel array?

为什么在这个像素阵列中绿色单元的数量是其他颜色的两倍？
