血液是人類生命的靈丹妙藥，也是日益稀缺的商品。儘管血液的需求增加，血液捐贈者卻在下降。研究人員和醫生正在尋找解決方案，有一種方法是減少輸血次數，另一種方法是收集人體血液的替代品：例如，來自海蚯蚓和幹細胞上取得。

Blood is the elixir of human life and an increasingly scarce commodity. This is because blood donation rates are down despite an increase in need. Researchers and doctors are searching for solutions. One approach is to reduce the number of transfusions. Another,to glean a substitute for human blood: from lugworms, for example, or stem cells.

世界上有成千上萬個眾所周知的昆蟲種類，有時，牠們的天賦類似於超能力。仿生學是一門科學，透過調查生物的結構和作用來應用於現代科技：例如，你永遠不會看到螞蟻塞車；亞洲長臂天牛擁有世界上最有效的免疫系統，這裡有兩個範，來看昆蟲們如何幫助我們解決當代問題。

There are more than a million known species of insect in the world. Sometimes, their talents are akin to superpowers. Bionics is a science that examines ways to apply biological structures and processes to modern technology: for example, you’ve never seen an ant traffic jam. And the Asian harlequin beetle has the most efficient immune system in the world. Two examples of how insects can help us to solve contemporary problems.

在海平面以下2000米處，它是黑暗的，水壓非常高，海底泉水噴出含有有毒物質的熱水，這些惡劣的條件不會阻止細菌繁殖，且形成富含無數高等生物的豐富生態系統的基層。這些生物間存在著什麼關係？關於細菌對人類生存的重要性，可以得出什麼結論？

2,000 meters below sea level it’s dark, water pressure is extremely high and undersea springs spew boiling hot water containing toxic substances. These hostile conditions do not deter bacteria, which flourish and form the basis for rich ecosystems with innumerable higher organisms. What is the relationship between these life forms？ And what conclusions can be drawn concerning the significance of bacteria for human existence？

到處都可見蜘蛛，牠們一直在我們周圍且生存在我們日常生活中，牠們和人類同居但往往不受人類的歡迎。也許這就是為什麼我們不想知道牠們所有的秘密。例如，很少有人知道有些蜘蛛可以飛行，有些可以在水中生活，而有些則會吐絲或跳舞。到目前為止，還沒有人發明出具有與蜘蛛絲相同的令人難以置信的品質的技術材料。

Spiders are everywhere we go, they’re around us all the time as we go about our daily lives, but they’re often not very popular with their human cohabitants. Maybe that’s why we haven’t wanted to know all their secrets. For example, few people are aware that some spiders can fly, some can live underwater, while others spit or dance. And so far, no one has managed to invent a technical material with the same incredible qualities as spider silk.
