Is this enough, or should we show them what's behind this door?

這樣就夠了，還是應該讓他們看看這扇門後面有什麼？

Too scary?

太嚇人了？

I know.

我知道

Let's close that up and open up this video with a question: What if you could regenerate like Deadpool or Wolverine? Triangle Bob volunteered to be the Deadpool dummy here.

最後，我們以一個問題開始這段視頻：如果你能像死侍或金剛狼一樣再生，會怎麼樣？三角鮑勃自願成為死侍的假人。

Hey there!

你們好

Welcome to Life Noggin.

歡迎來到 Life Noggin。

Deadpool and Wolverine have incredible healing abilities and can even regrow lost limbs overnight, making them practically immortal.

死侍和金剛狼擁有驚人的癒合能力，甚至可以在一夜之間重新長出失去的肢體，使他們幾乎永生不死。

This superpower is known as a healing factor, and it's linked to their status as mutants. Before you come for me, I know that Deadpool is a mutate in the comics, but we're talking about movie Deadpool today.

這種超能力被稱為治癒因子，與他們的變種人身份有關。在你們來找我之前，我知道死侍在漫畫中是變種人，但我們今天討論的是電影《死侍》。

And in the movies, Deadpool was born with superhuman genes that were activated with the serum.

而在電影中，死侍天生就有超人基因，並被血清激活。

Now, these genes accelerate the natural healing and regeneration processes present in the human body.

現在，這些基因可以加速人體的自然癒合和再生過程。

Yes, I mean normal, non-superhero human bodies. How do you think your skin and bones heal?

是的，我指的是正常的、非超級英雄的人體。你覺得你的皮膚和骨頭是怎麼癒合的？

Of course, regenerating an entire organ or limb is another story, and isn't something your body does.

當然，再生整個器官或肢體則是另一回事，這不是你的身體所能做到的。

At least for now.

至少現在是這樣。

Ooh, Triangle Bob, that one looked like it hurt. Scientists have been hard at work trying to turn you normal humans into superhumans.

哦，三角鮑勃，那個看起來很疼。科學家們一直在努力工作，試圖把你們這些普通人變成超人。

And while you're still a ways off from needing a super suit, they've made some pretty impressive progress.

雖然你還不需要超級宇航服，但他們已經取得了一些令人印象深刻的進步。

One avenue they're exploring is the use of materials containing or mimicking the extracellular matrix found in all tissues and organs.

他們正在探索的一個途徑是使用含有或模仿所有組織和器官中的細胞外基質的材料。

The ECM is essentially a scaffold that provides support and structure, but it also plays an important role in cell growth and tissue repair. Researchers are trying to accurately recreate it with biomaterials or donor organs and tissues.

ECM 本質上是一種提供支撐和結構的支架，但它在細胞生長和組織修復中也發揮著重要作用。研究人員正試圖利用生物材料或捐獻的器官和組織準確地再造它。

They then attempt to grow new components around it using stem cells, which can develop into any type of cell.

然後，他們嘗試利用幹細胞在其周圍生長出新的成分，幹細胞可以發育成任何類型的細胞。

While moving this technology into the clinic will require lots more research, scientists have already grown human hearts, lungs, and even teeth. But ECMs aren't the only way to regrow limbs.

雖然將這項技術應用於臨床還需要更多的研究，但科學家們已經培育出了人類的心臟、肺甚至牙齒。但是，ECM 並不是再生肢體的唯一方法。

In the animal world, where regeneration is a reality, scientists have found that some animals activate certain genes to stimulate regrowth.

在動物世界中，再生是一種現實，科學家發現，一些動物會激活某些基因來刺激再生。

Take the starfish.

就拿海星來說吧。

Is that a starfish dressed up like Wolverine?

那是一隻打扮得像金剛狼的海星嗎？

That's really cute, animator.

真可愛，動畫師

Thank you for doing that.

謝謝你這麼做。

They not only regrow an entire body from just an arm, but a nervous system, too. Since regenerating brain cells is rare, scientists took a closer look at how it happens and discovered that injured starfish express a gene that reactivated mechanisms used during development.

它們不僅能從一隻手臂再生出整個身體，還能再生出神經系統。由於腦細胞的再生非常罕見，科學家們仔細研究了它是如何發生的，發現受傷的海星會表達一種基因，重新激活發育過程中使用的機制。

Basically, cells reverted to a stem cell-like stage where they could then become brain cells.

基本上，細胞恢復到了類似幹細胞的階段，然後可以變成腦細胞。

This same gene can revert adult human cells into stem cells.

同樣的基因可以將成人細胞轉化為幹細胞。

So if scientists can harness this mechanism, they could regenerate all kinds of cells. Currently, scientists can make stem cells from adult cells through a chemical process that resets their epigenetics, which are the on and off switches on the genes.

是以，如果科學家能夠利用這一機制，就可以再生出各種細胞。目前，科學家可以通過化學過程從成體細胞中製造幹細胞，重置其表觀遺傳學，即基因的開關。

It's thought that activating these switches is what turned on Deadpool's healing factor.

人們認為，正是激活了這些開關，才開啟了死侍的治癒因子。

But there are other ways to use genes to stimulate growth.

不過，還有其他方法可以利用基因來刺激生長。

Different kind of genes, Grieg, but good to know you eat genes, I guess. For instance, some scientists are developing a drug that can stop a certain gene from preventing tooth growth.

基因的種類不同，格里格，但我想，知道你吃基因是件好事。例如，一些科學家正在研發一種藥物，可以阻止某種基因阻礙牙齒生長。

And after successfully growing teeth in mice and ferrets, clinical trials are approved to begin any day now.

在小鼠和雪貂身上成功長出牙齒後，臨床試驗已獲准隨時開始。

Another mechanism scientists are trying to harness is the body's electrical signals.

科學家們試圖利用的另一種機制是人體的電信號。

This bioelectricity is how your cells communicate, telling its neighbors to heal a wound or grow an eyeball. By controlling these signals, scientists have stimulated the growth of extra brain tissue in frog embryos, strengthened the immune system response of tadpoles, and made flatworms grow an extra head.

這種生物電是細胞進行交流的方式，它告訴周圍的細胞癒合傷口或長出眼球。通過控制這些信號，科學家們刺激了青蛙胚胎中額外腦組織的生長，加強了蝌蚪免疫系統的反應，還讓扁形蟲多長出了一個頭。

Okay, Animator, Triangle Bob is just a triangle at this point, so can we get him some help? While it's going to take a while before you can regrow your hand overnight, you may be a lot closer than you think.

好了，動畫師，三角鮑勃現在只是個三角形，我們能幫他一把嗎？雖然要想在一夜之間讓你的手重新長出來還需要一段時間，但你可能比你想象的要快得多。

So, which superhero movie do you think is the best out of the 692 that have been out?

那麼，在已經上映的 692 部超級英雄電影中，您認為哪部最棒？
