Is living with pets really good for our health

An American researcher has published a book called, “ Some We Love, Some We Hate, So We Eat” about our relationship with animals.

He’s reviewed the studies suggesting that living with pets is good for our health. And he’s sceptical. He says that for every study saying it is, there are many studies that find no difference.

Thirty years of Australia China collaboration

Next week Australia and China will celebrate 30 years of partnership in science.

During the past three decades Australian and Chinese researchers have worked together on projects to reduce child mortality rates, treat eye and skin disease using lasers and captured solar energy.

For example the world’s largest maker of silcon solar panels uses Australian technology. The company was founded by Australian/Chinese engineer Zhengrong Shi who is now one of the richest people in China. He says that in a few years solar electricity will be as cheap as coal.
