The Fairy Penguin

Webbed feet

Fairy penguins are the smallest of all the penguins in the world. They live in the south of Australia and in New Zealand.

Fairy penguins weigh (重) about one kilogram. They stand thirty centimeters (厘米) tall. Their back feather (羽毛) are dark blue and their front feathers are white. They have a beak and webbed feet.

Fairy penguins live on the land and in the sea. They are very good swimmers but they cannot fly. They eat small fish.

Fairy penguins breed (繁殖) on land. The mother penguins lay two white eggs in a hole. The mother and father penguins share the job of sitting on the eggs.

When the baby penguins come out, the mother and father penguins bring food from the sea. In eight weeks the baby penguins can have grown feathers. They are soon ready to look for their own food. Fairy penguins are often in danger. Wild animals eat them; people catch them; they have no place to live in. If their numbers become too small, these little penguins might leave our world forever.

Imagine having an ear made out of an apple. It seems like a crazy idea. But it could happen in the near future.

Canadian biophysicist Andrew Pelling used an apple to grow a human ear. He thinks fruit and vegetables can be used to cheaply repair human body parts in the future.

Scientists have been trying to grow organs in labs to replace our old ones. But it‘s a hard job. In the past, scientists have used man-made materials, animal parts and even dead people as scaffolds(支架). But that has proved to be difficult and expensive.

Pelling and his team, however, found the apple to be a cheap and easy-to-use scaffolds.They first cut an apple into the shape of an ear. Then they used a special way to take out the apple‘s cells(细胞)and make it a scaffold. The team then added human cells to the apple, and watched it grow. “You can implant(移植)these scaffold into the body, and the body will send in cells and a blood supply and actually keep these things alive, ” Pelling said during a Ted Talk speech.

The team put the apple scaffold inside a living mouse and the mouse’s cells slowly take over the pieces of the apple.

Now Pelling is thinking of the other fruit, plants or vegetables to use.
