Scientiststried to find ways to reprogram cells for years. They tend to use as less aspossible genes to reduce the chance of cancer. They were kind of stuck by usingOct4 until a Chinese team took an indirect approach. There were some barriers.But now, the new way to reprogram has reached some significant achievements. Wejust need to wait more proof that the technique is safe for human.

Thestructure of mammal gene- one X doesn’t show the function. Compare genesbetween human beings and mice-we share majority of the gene-most of the unsharedgene is contained in X-X changed from time to time and create the evolution-unsharedX gene are active in testis to create new life.

Scientistsdiscovered a new study about the natural leadership shift among a flock ofanimal.

-whybirds fly in group and how do they change direction and who is the leader

-usingcomputerized GPS, camera and system make it possible to track the motion ofeach one in the group

-trackthe leader on the ground and in the air, combine the results together for thefirst time

-howdo they change direction and the leader on the ground is not in charge of thegroup

-howdo they choose leader is still not clear and need more research

躺在床上想想每天的阅读感觉都不知道自己在读什么，可能 只有那一瞬间的记忆，然后很快就忘记了，这不是正确的阅读嘛！
想想中文的阅读，不管读得如何走马观花，都会有一个大致的意思比较长久地存在在脑海里。
所以决定每天读完写完回忆再用中文写一下大纲。希望会有改进！！！

time1:1'56/208
     a seccessful study of reprogram adult tissue without genes
     the professor used an indirect way to complete the experience:reprogram the cells without Oct4
time2:1'25/194
     several problems in the experience were overcame by the researchers
     the CiPS cells can reprogram various cell types in mice
time3:2'13/291
     some new finding about the Sall4 in the frogs
     only when the researchers prove this method is safe and effective in humans will it be applied in clinic.
一个新的生物研究，用人工合成的化合物代替基因完成细胞重组，并生长出新的组织和器官。

我忽略重要名词的关系，回看才抓住它们的关系，摘出来做警示。
Now, writing in Science, researchers report success in creating iPS cells using chemical compounds only — what they call CiPS cells.

time4：3'11/392
     new research finds that X chromosome also has influence on maleness
     Page did some researchs to prove that mice and humans share some sexual genes
time5：2'51/356
     there are large difference between mouse X chromosome and human X chromosome, suggesting that chromosome might be changing all the time
     these unique genes of human X chromosome are proved to be active in the testis and sperm
     more evidences are needed to prove thes unique genes' function, especially related to male fertility
X染色体可能对于男性生育力和相关癌症等也有重要影响。

obstacle:6'30/864
     main idea: leadership in flight
     attitude: objective
     structure: raise a new finding about the leadership in the flight: even birds with a low social rank on the ground may be trusted leaders in the air
                explain how to implement the experiment and the results of it
                introduce the surprising finding: birds do not choose their leaders in the air according to the aggressiveness but the actual criteria is not clear
                the application in other animals
天空的领导者不一定是地面的领导者。

1. 2分26秒
   Researchers are trying to find chemicals to do the reprogram of cells for adults, cuz genes can sometimes bring out cancer. But however hard they try, Oct14 is always the one gene that needed.
   Hongqing Deng and his team in Peking University recently are using an indirect way to find the substitutes: searching molecule compounds that could reprogram the cells using other genes except for Oct4.

2. 2分07秒
They finally found one molecule that could reprogram cells in early stage but only in small ones. However, by adding DZNep, the effect can turn out to be close to the iPS results. (回忆错误)And through applying to animals, it shows that the chemical can be effective for most of the common cells.
RJ said that the paper shows ppl how molecules can replace all factors


3. 2分30秒
The achievement by Deng's group can contribute to the biologic work. Once comfired, it can be applied for clinic use and can cause significant progress for its safety.

刚开始先这样。。3篇。。听神猴老大的每天拨出1小时。。然后稳打稳扎。。
我要提高阅读水平！！！！！

觉得科技类的文章有难度。。。占座 昨天的还没补

我发现占座之后好像打字更不方面唉。。以后不占了。。。。。。。。

hongkui deng a biologist in peking university anncounced that he with his team can reprogramme cells in the stem
without gene Oct4
1:25
reseachers produce small cells that can be used to develop mouse embryos.
2:20
reseachers still needs to do experiment to test whether they can apply this cell to homan
3:03
02:54
X chromosome is evovling continuiouslly and reseachers hope to understand these genes and impact on health and speciation
