When cold weather comes, many birds move to warmer places to find food.Some fishes give birth in warm water and move to cold water to feed.The most famous migration (迁移) is probably the migration of the fish which is called “salmon”. This fish is born in fresh water but it travels many miles to salt water.There it spends its life.When it is old, it returns to its birthplace in fresh water.Then it gives birth and dies.In northern Europe, there is a kind of mouse.They leave their mountain homes when they become too crowded.They move down to the low land.Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea.

Recently, scientists have studied the migration of a kind of lobster (龙虾). Every year, when the season of the bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean.Nobody knows why they do this, and nobody knows where they go.So, sometimes we know why humans and animals move from one place to another, but at other times we don’t. Maybe living things just like to travel.

【推荐1】Up till about 130 years ago, newspapers in the United States attracted only the most serious readers. They used no illustration (插图) and the articles were about politics or business.

Two men changed that - Joseph Pulitzer bought the New York World and William Randolph Hearst of the New York Journal. Pulitzer bought the New York World in 1883. He changed it from a traditional newspaper into a very exciting one overnight. He added lots of illustrations and he told his reporters to write articles on every crime they could find. And they did. One of them-a woman reporter, even pretended she was mad and was sent to a hospital. She then wrote many articles about the poor treatment of patients in those hospitals where mad men were kept.

In 1895, Hearst came to New York from California. He wanted the Journal to be more exciting than the World. He also wanted it to be cheaper, so he lowered the price to a penny. Hearst attracted attention because his newspaper headings were bigger than anyone else’s. He often says, “Big print makes big news.”

Pulitzer and Hearst did anything they could to sell newspapers. For example, Hearst sent Frederic Remington, the famous illustrator, to draw pictures of the Spanish-American War. When he got there, he told Hearst that no fighting was going on, Hearst answered, “You provide the pictures. I’ll provide the war.”

The self-cleaning door handle is combining with advanced photocatalytic ( 光 催 化 ) and blacklight technology. A light source activates the door’s handle coating, telling it to start cleaning. It can minimize the risk of infection by contact and improve the cleanliness of a space.

The working principle of the product is that a thin advanced photocatalytic coating can effectively decompose bacteria ( 细 菌 ) on the surface of a substance. A consistent UV light source—inside a transparent glass door handle—is required to activate the door’s handle coating on the outer surface for disinfection, so a generator is used to provide electricity to light up a UV LED lamp by the motion of an opening and closing door. Then, the door handle can clean by itself.

We made the first version by using stainless steel. However, it caused the door handle to be heavier. Then, we tried aluminum, which made it light and easy to fix. We also improved the generator output which effectively turned energy from door movement into a light source.

Our innovative design is simple, effective, and attractive. It has an elegant smooth shape, and its minimalist appearance stands out in today’s world of inventions. Nowadays, people use chemical cleaning materials to clean up public areas but it harms the human body. Our design can be used for a long time and is effective. It can self-clean after each use. In the door lock and door handle market, it is a unique design because there are no similar products.

In the future, we will commercialize the product and hope that it can compete on the market with similar products. We are going to connect with public properties, for example, shopping malls, hotels, hospitals and public restrooms, where the risk of spreading infection is higher.

In addition to winning the James Dyson Award, it has also received the Gold Award, and in 2016, it was featured in the 44th International Geneva Inventions Exhibition.
