能瘦身又能降血糖，斷食還能讓人長壽嗎？讓 Life Noggin 帶你剖析！ (Can Fasting Help You Live Longer?)
03:59
- In your liver, fat is turned into ketone bodies, which control the activity of many proteins and molecules that influence health and aging.
在肝臟中，脂肪會轉化為酮體、它們控制著許多影響健康和衰老的蛋白質和分子的活性。
- which control the activity of many proteins and molecules that influence health and aging.
它們控制著許多影響健康和衰老的蛋白質和分子的活性。
【科學知識】「東西」究竟是什麼組成的？(What Is Something?)
05:34
- You are matter, which is made of molecules, which are made of atoms, and those are made of elementary particles.
你是物質做的，物質是分子做的，分子是原子做的， 原子是「基本粒子」做的。
DNA 很重要，但究竟多重要呢？來看看 DNA 的發現如何改變了世界和諾貝爾獎得主的生活 (How the discovery of DNA changed the world – and my life | BBC Ideas)
05:55
- It shows two long chains of molecules spiralling around each other in a double helix, like a twisted ladder.
它顯示了兩條長鏈分子以雙螺旋形式相互纏繞，就像一個扭曲的梯子。
螢幕真的會傷眼嗎？ (Can Screens Damage Your Eyes?)
03:45
- The light reacts with certain molecules, knocking off bits of them and creating reactive oxygen species, or ROSes, which will bond with almost anything.
光會與某些分子發生反應，並將其中一些分子除去，創造出活性氧分子或叫 ROSes，它們幾乎會與所有物質結合。
- The 470 nanometer light, which was a sort of turquoise, just didn't have enough energy to effectively break apart molecules.
470 奈米的光有點像藍綠色，它沒有足夠的能量來有效分解分子。
樹木如何度過冬天？ (How do Trees Survive Winter?)
02:49
- The ice itself doesn't cause much harm, but when it thaws, the bubbles remain, which is a problem because the whole plumbing system relies on the inter-molecular attraction of water molecules pulling each other upward against gravity.
冰本身並不會造成太多傷害，但當它融化，氣泡會留下，這就造成問題了，因為整個水管系統是依靠水分子間的作用力，將每個水分子抵抗重力向上拉。
- Air bubbles break the chain of molecules, essentially shutting off the flow of water.
氣泡會中斷這一串分子鏈，本質上阻斷了水的流動 。
為什麼自然界中的藍色如此罕見？ 藍色是一種顏色還是視錯覺？ (Why is the Color Blue So Rare in Nature? Is blue a color or optical illusion?)
04:09
- But unlike red, brown, orange, and yellow, blue in the nature isn't a pigment at all, rather this color is caused by the structure of molecules, how they reflect light, and the way that we see this reflected light.
但與紅色、棕色、橙色和黃色不同。自然界中的藍色根本就不是一種顏料。 相反，這種顏色是由分子的結構造成的。 它們是如何反射光線的。 以及我們看到這種反射光的方式。
- rather this color is caused by the structure of molecules,
相反，這種顏色是由分子的結構造成的。
外星人究竟是否存在？ (Alien life: are we about to find it?)
10:11
- And biosignatures is a very loose term⏤what it basically means is specific molecules are only associated with life.
生物特徵是一個非常廣泛術語，基本上就是表示只跟生命相關的特定分子。
- Astrobiologist Sara Seager has identified at least 3,500 molecules that could be biosignatures.
天體生物學家 Sara Seager 已經至少辨識了 3,500 種可能是生物特徵的分子。
真的會爆炸嗎？！為什麼金屬製品不能放微波爐裡？ (Why Can't I Put Metal in the Microwave?)
02:33
- Safely contained in the box, these microwaves can pass through glass, paper, and plastic until they're absorbed by the water molecules in your food.
這些微波安全地存放在盒子中，可以穿過玻璃、紙張和塑料，直到被食物中的水分子吸收。
