Since its invention 100 years ago, plastic, the superstar of the technological age, has become ugly and ungreen. But that’s about to change. An exhibition at London’s Science Museum this week could put it back on the cutting edge of science.

Have you ever hesitated in donating blood? The invention of “plastic blood” might make you feel better.

British scientists are working on the artificial blood as a replacement for real blood in emergency situations. It is made of plastic molecules (分子) and can join oxygen and transport it around the body. As a red, honey - like glue, plastic blood can be carried around conveniently. You just add water to make as much blood as you need.

The cells of our body are strict about what molecules they let in and out. For example, if we inject protein or DNA directly into the body, our immune (免疫的) system will destroy it before it reaches the cells.

To get around this, a British scientist has created drug-carrying plastic balls that fool the body into thinking they are natural. Once inside the cell, their contents are spread out through a small controlled explosion.

Skin transplants are widely done these days. But removing a piece of skin from, say, the bottom to plant it on the face can hurt and be troublesome.

A British company, CellTran, is working on plastic skin. Using plastic, they plan to take a small piece of the patient’s skin and grow it into an extra layer of skin on top of the plastic.

The plastic feels similar to skin, so skin cells like to grow on it. The plastic then gradually disappears, without any reaction or infection.

You don’t need millions to be happy. In fact, at The Happiness Institute in Australia, a couple of hundred dollars may be enough.

The institute opened its door last year, and, since then, men and women of all ages have been paying $ 200 an hour for lessons on how to feel great.

“You can actually increase your happiness levels. That’s what we teach,” said Timothy Sharp, founder of the institute.

Experts say that only about 15 percent of happiness comes from income, assets (财产)and other financial factors. As much as 85 percent comes from things such as attitude, life control and relationships.

Most of us are significantly better off financially than our parents and grandparents, but happiness levels haven’t changed to reflect that.

Studies show that once the basic needs of shelter and food are met, additional wealth adds very little to happiness.

Many decades ago, the sage (圣人、哲人)of Baltimore, Maryland”, editor HL Mencken, defined wealth as earning $100 more than your “wife’s sister’s husband”.

Behavioral economists now say part of the reason we are richer but not happier is that we compare ourselves to people better off materially.

“The argument is that if you want to be happy there’s a very simple thing you can do:

Compare yourself to people who are less well off than you---poorer, smaller house and

car,” said Sharp.

The Happiness Institute aims to show you how to overcome these unhappiness factors by focusing on “more than just your bank account”.

“If I compare myself to Bill Gates then I’m always going to be down,” said Sharp.

A better thing to compare with, he said, might be Kerry Packer, Australia’s richest person who has had a kidney (肾脏) transplant and heart surgery in recent years.

D. Both Bill Gates and Kerry Packer are examples of those who are extremely rich but obviously unhappy.
