We're interested only really in two things: One, can you differentiate between duple and triple meter; and two, can you recognize some very basic rhythmic patterns?

我们这里只关注两件事,一,你能不能区分两拍子和三拍子,二,你能不能识别一些简单的基本节奏形式

How we could take cells that are differentiated to some extent and make them de-differentiate, to go back in the process of differentiation so that they gain more potential.

These signaling proteins play important roles in determining how many cells differentiate down particular pathways and they turn out also to be very useful for treating diseases of those pathways.

这些信号蛋白在决定特定分化路径上,有多少细胞在分化时起着重要作用,且在治疗疾病方面也很有用,同样也是利用这些机制

Now, you'll hear reports in the literature, you'll look in the newspaper, you'll hear about scientists that have found ways to trans-differentiate cells, that is move them from one pathway to the other.

如今,你通过听文献讲座,看报纸,会听说科学家们已经发现了,转分化细胞的方法,即把这些细胞从一种分化途径转到另一种

Well, it would be useful because if I could take cells from the skin, find stem cells in the skin and then de-differentiate them so that they were now capable of becoming liver, or brain, or things that they're not going to become in their normal site, then that could be a very powerful tool for medicine.

这是因为,如果我能取一些皮肤细胞,找一些皮肤干细胞,并将它们去分化,那它们就能分化成肝脏,大脑或其他一些,它们原本分化不出来的细胞,这可以成为一个医学利器
