英語聽力(20200321T06):自受孕至出生——可視化


聽力原文如下

<code>1.I was offered a position as associate professor of medicine and chief of scientific visualization at Yale University in the department of medicine.
我曾被耶魯大學的醫學系 提供了 一個副教授和 科學可視化主任的職位
2.And my job was to write many of the algorithms and code for NASA to do virtual surgery in preparation for the astronauts going into deep spaceflight,
我的工作是為美國國家航天局NASA寫 幫助NASA做虛擬手術用的程序和算法 虛擬手術用於為深空宇航飛行做準備的宇航員
3.so they could be kept in robotic pods.
(好把他們凍起來)。
4.One of the fascinating things about what we were actually working on is that we were seeing, using new kinds of scanning technologies,
我們工作中很吸引人的一件事就是 我們能利用最新的掃描科到
5.things that had just never been seen before -- I mean, not only in disease management, but also things that allowed us to see things about the body
看到從前根本無法看到的東西 —— 我意思是,不只是病菌和疾病有關係的 還可以看到
6.that just made you marvel.
令人驚歎的人體
7.I remember one of the first times we were looking at collagen.
我記得有一次我們在研究膠原蛋白
8.And your entire body, everything -- your hair, skin, bone, nails -- everything is made of collagen.
整個人體,所有的東西 你的頭髮、皮膚、骨頭、指甲 …… 所有的東西都是膠原蛋白組成的。
9.And it's a kind of rope-like structure that twirls and swirls like this.
它是有繩子一樣的結構 就這樣擰來擰去的(看手勢)。
10.And the only place that collagen changes its structure is in the cornea of your eye.
而膠原蛋白唯一改變結構的地方 就在眼角膜裡。
11.In your eye, it becomes a grid formation, and therefore, it becomes transparent, as opposed to opaque.

在眼睛裡 它會變成一個網格結構 而因此它就變透明瞭,而不是(猶如指甲般)半透明。
12.So perfectly organized a structure, it was hard not to attribute divinity to it.
組織的如此完美的一個結構, 很難不把這說成是神威所致
13.Because we kept on seeing this over and over and over again in different parts of the body.
因為我們會不斷看到這個(變化),一遍又一遍的 在身體各個不同的位置。
14.One of the opportunities I had was one person was working on a really interesting micromagnetic resonance imaging machine with the NIH.
我曾經有個機會 和另一位為美國國家衛生研究院工作的 研究微型磁共振成像機的人共事
15.And what we were going to do was scan a new project on the development of the fetus from conception to birth using these kinds of new technologies.
我們要做的是 利用這些新科技 為一個關於胎兒發育的 新項目做掃描
16.So I wrote the algorithms in code, and he built the hardware -- Paul Lauterbur -- then went onto win the Nobel Prize for inventing the MRI.
我還是寫我的算法和程序 而他,保羅·勞特伯爾,則負責硬件 他的磁共振成像後來贏得了諾貝爾獎
17.I got the data.
(但是數據還在我這兒)
18.And I'm going to show you a sample of the piece, "From Conception to Birth."
我這就給大家看這研究的一個樣片 “從受孕至出生”
19.(Music) Video text: "From Conception to Birth"
??音樂? “從受孕至出生”
20.Oocyte Sperm Egg Inseminated 24 Hours: Baby's first division The fertilized ovum divides a few hours after fusion ...
卵母細胞 精子 卵子被受精 第24個小時:嬰兒“第一個分裂” 受精卵融合幾個小時後開始分裂
21.And divides anew every 12 to 15 hours.
差不多12至15小時分裂一次

22.Early Embryo Yolk sack still feeding Baby.
胚胎早期 卵黃依然給予胚胎營養
23.25 Days: Heart chamber developing 32 Days: Arms & hands are developing 36 Days: Beginning of the primitive vertabrae These weeks are the period of the most rapid development of the fetus.
第25天:心室正在發育 第32天:胳膊和手開始成型 第36天:原始脊椎出現 這幾個星期是胚胎髮育最快的階段
24.If the fetus continues to grow at this speed for the entire nine months, it would be 1.5 tons at birth.
假設胎兒九個月都在以這個速度生長…… 它將會以1.5噸的重量出生
25.45 Days Embryo's heart is beating twice as fast as the mother's.
第45天 胎兒的心速是母親的一倍
26.51 Days 52 Days: Developing retina, nose and fingers The fetus' continual movement in the womb is necessary for muscular and skeletal growth.
第51天 第52天:發育中的視網膜,鼻子和手指 胎兒在子宮中不斷地活動 有必要幫助肌肉及骨骼的生長
27.12 Weeks: Indifferent penis -- girl or boy yet to be determined 8 Months Delivery: the expulsion stage The moment of birth (Applause)
第12周:性別未分化的陰莖 男孩女孩無法分辨 八個月 分娩:生產階段 生命的奇蹟 掌聲
28.Alexander Tsiaras: Thank you.
感謝大家
29.But as you can see, when you actually start working on this data, it's pretty spectacular.
由此可見 當你開始處理這些數據的時候 其實是很壯觀的
30.And as we kept on scanning more and more, working on this project, looking at these two simple cells that have this kind of unbelievable machinery
當我們繼續掃描 做這個項目的時候 看到這兩個很簡單的細胞 擁有這種難以置信的機械構造
31.that will become the magic of you.
而這最終會變成一個人
32.And as we kept on working on this data, looking at small clusters of the body, these little pieces of tissue that were a trophoblast coming off of a blastocyst,
當我們繼續加工這數據 看著身體的這些小小的部分 這一小團組織 從懷胎分化出來的滋養細胞群

33.all of a sudden burrowing itself into the side of the uterus, saying, "I'm here to stay."
轉眼嵌入了子宮壁 與子宮開始溝通
34.All of a sudden having conversation and communications with the estrogens, the progesterones, saying, "I'm here to stay, plant me,"
與雌激素和孕酮溝通 說:我要留下 說:我要留在這,養育我
35.building this incredible trilinear fetus that becomes, within 44 days, something that you can recognize, and then at nine weeks is really kind of a little human being.
逐漸成為這個三胚層胚胎 在44天左右 胚胎便可以辨認 並在九周內 基本就變成一個小人
36.The marvel of this information: How do we actually have this biological mechanism inside our body to actually see this information?
