  • Many animals and plants have developed ways to solve problems that are similar to the ones we humans have to deal with.
  • Part One
  • Scientists often look at nature in order to find new ideas.
  • In ancient times,Chinese scientists studied how spiders made silk.
  • Modern scientists are interested in the spider too.
  • The spider can make silk that is much stronger than most man-made materials.
  • Spider silk doesn't break easily,instead of breaking,it gets longer.
  • Best of all,
  • the spider produces the silk without the use of dangerous or poisonous chemicals
  • If we could learn to use the technique,
  • we might be able to use the strong silk to make things like seat-belts and wires that hold up bridges.
  • Part Two
  • There are many other examples of how new technology has been developed by learning from nature.
  • A group of German scientists wanted to find out why leaves and flowers are able to stay so clean.
  • They decided to take a closer look at the white lotus,
  • a flower that is know for it's cleaning leaves.
  • At first,the scientists believe that the very flat leaf
  • would be better with stain clean.
  • However,when they looked closely at the white lotus,
  • the scientists saw that the leaf was in fact covered with tiny hairs and needles.
  • The needles and hairs collect the dust that falls on the leaf.
  • So that a rain drop can easily wash it out.
  • The German scientists use this technic to design a new kind of paint.
  • The new paint could keep out as looking clean for years.
  • Scientists also believe
  • that the butterfly could teach us a way to keep our computers cool.
  • A computer must be kept cool to function well.
  • The fans we use today are not always good enough.
  • The butterfly is cold-blooded and must change its body temperature all the time.
  • Scientists have found that there are small parts on the two wings
  • of the butterfly uses to change its temperature.
  • If scientists can learn how it has done,
  • it maybe possible to use the same method to keep computers from becoming too hot.
