Blood Types: A Life-saving Discovery

How one scientist changed the way the world saw blood – and won a Nobel Prize

For centuries, scientists experimented with transferring blood between people - usually with fatal results. In their experiments, they noticed that sometimes during blood transfusions the red blood cells clumped together causing a toxic reaction.

In the early 20th century, Austrian scientist Karl Landsteiner discovered this was caused by a reaction to the donor's blood. He categorized people into four blood groups - A, B, AB and O - based on the proteins in their blood. Receiving blood from a donor whose blood type was not compatible would hurt or kill a patient.For this discovery, Landsteiner received the 1900 Nobel Price in Physiology of Medicine.

Many Asian people believe that one's blood type relates to one's personality. People with blood type A are seen as loyal and having high standards but as too anxious. Type B people are considered creative and optimistic but selfish. Those with type AB are considered rational, calm and controlled. Type O people tend to be friendly, passionate and ambitious but stubborn. Movies, comics and dramas draw on this idea. In Japan, some people even make dating and hiring decisions based on blood types!

One book proposed that blood types reveal people's ideal diets and lifestyles. However, little scientific evidence supports blood-type diets or personality tests. Maybe more study of this will lead to another Nobel Prize!

the Nobel Prize 諾貝爾獎

Many people believe the Nobel Prize is the highest honor one can receive. Steve, what do you think of that?

Well, the Nobel Prize is certainly very prestigious. To receive one in any of its categories, whether it’d be Literature, Medicine, Physics, Chemistry, Peace or Economics, is indeed a high honor.

Now the word we use for recipient of the Nobel Prize is laureate. Mother Teresa was a Nobel laureate, and so was President Barack Obama.

And as the name indicates, the Nobel Prize was created by Alfred Nobel, a Swedish chemist who invented dynamite in the late 19th century.

While he made a fortune from his invention, he didn't want to be remembered as the man who created something people used in war to kill and destroy.

So before he died, he wrote a will specifying that his fortune be used to create prizes for those who give the greatest benefit to mankind.

So what does a Nobel laureate receive? A gold medal, a diploma and a sum of money.

And the amount? About US$1.2 million.

諾貝爾獎的起源:諾貝爾獎是依黃色炸藥(dynamite) 發明人 Alfred Bernhard Nobel (1833- 1896)的遺願,因為他感到自己發明的炸藥很痛心, 於1901年開始,按其遺產孳息所設立的獎,諾貝爾獎包括物理、化學、醫學、文學、和平及經濟等六種獎項;每年 12月10日,即諾貝爾先生逝世紀念日,在瑞典斯德哥爾摩頒發,其中和平獎在挪威奧斯陸頒發。 諾貝爾獎是頒發給各相關領域中,具有重大發現、重要發明或特殊貢獻者。

to draw on something: to get or take ideas from

Hello, friends. Welcome to the Grammar Gym. My name is Liz. So we’re talking about blood types in today’s article. And the writer mentions that many Asian people believe that one’s blood type relates to one’s personality. It’s such a popular idea that the writer mentions “Movies, comics and dramas draw on this idea.” That’s our Grammar Tip sentence.

Our focus is on the phrase: to draw on something. Normally we use “draw” to mean to make a picture.
But in today’s sentence, “to draw on something” means to get or take ideas from. In other words, this idea of how one’s blood type relates to one’s personality is used in Asian movies, comics and dramas.

Let’s look at some examples:
Jackie drew on her school counselor’s advice and decided to major in business.
Or: For our new writing assignment, the professor wants us to draw on the concept of time travel.

Now it’s your turn. What can you draw on? Think of ways where you get ideas, and practice making your own sentences. That’s it for today. This is Liz from the Grammar Gym. See you next time.
