Scientists Make Simple Fake Cells

科學家製造出簡單的人造細胞


Introduction

Scientists at the University of Minnesota made fake cells. They call them SpudCells. These cells can grow and make copies of themselves.

明尼蘇達大學的科學家製造出人造細胞,他們將其稱為 SpudCells。這些細胞能夠生長並自我複製。

Main Body

The scientists used DNA and small fat bubbles to make the cells. The cells need special food and energy from outside to work.

科學家使用 DNA 和微小的脂肪泡來製造這些細胞。這些細胞需要從外部獲取特殊的食物和能量才能運作。

These cells can copy their DNA and split into two. Some cells grow faster than others. This is like how nature works.

這些細胞可以複製其 DNA 並分裂成兩個。有些細胞的生長速度比其他細胞快,這與自然界的運作方式相似。

But these cells are very simple. They cannot make their own energy. They cannot clean their own waste. They often stop working after a short time.

但這些細胞非常簡單。它們無法自行製造能量,也無法自行清理廢物。它們通常在短時間後就會停止運作。

Conclusion

The scientists started a new company called Biotic. They want other scientists around the world to use these cells.

科學家創立了一家名為 Biotic 的新公司。他們希望全世界的科學家都能使用這些細胞。

The Power of 'CAN' and 'CANNOT'

In this story, we see a very useful word to describe abilities: Can.

How it works: Use can for things that are possible. Use cannot (or can't) for things that are impossible.

Examples from the text:

  • Cells can grow \rightarrow (They have the ability)
  • Cells can copy DNA \rightarrow (They have the ability)
  • They cannot make energy \rightarrow (They are unable to do this)
  • They cannot clean waste \rightarrow (They are unable to do this)

Quick Rule: Subject + can/cannot + action word (verb).

  • I can speak English.
  • The cell cannot move.

Vocabulary Spot:

  • Fake: Not real.
  • Split: To break into two parts.
