Get a Life is a website that helps middle school students answer the question —What do you want to be when you grow up?

"It encourages teenagers to have a big dream; it tries to find out what is possible; it makes a plan for children to get where they want to go," said Combs, one of the persons who set up the website.

Get a Life suggests teenagers let their hobbies and interests decide what to do in the future. It encourages them to look for activities that help them try to do some jobs and get important knowledge and skills. It also offers information about fast-growing and well-paid jobs, and provides job training for teenagers.

"Middle school is the perfect time for students to find out their interests, to have many different experiences and do something for their future jobs," a middle school teacher said. "Our world will become a better place if we make our horizons wide and try new things. Our students can’t wait until high school or university to begin building their dreams. Right now is the right time to get a life."

"This website is exactly what these children need for a better future. If our children can make better plans for their future, it is more possible for them to succeed," Combs said.

Fish have ears. Really. They're quite small and have no opening to the outside world carrying sound through the body. For the past seven years, Simon Thorrold, a university professor, has been examining fish ears, small round ear bones called otoliths.

As fish grow, so do their otoliths. Each day, their otoliths gain a ring of calcium carbonate(碳酸钙).By looking through a microscope and counting these rings, Thorrold can determine the exact age of a young fish. As a fish gets older, its otoliths no longer get daily rings. Instead, they get yearly rings, which can also be counted, giving information about the fish's age, just like the growth rings of a tree.

Ring counting is nothing new to fish scientists. But Thorrold has turned to a new direction. They're examining the chemical elements of each otolith ring.

The daily ring gives us the time, but chemistry tells us about the environment in which the fish swam on any given day. These elements tell us about the chemistry of the water that the fish was in. It also says something about water temperature, which determines how much of these elements will gather within each otolith ring.

Thorrold can tell, for example, if a fish spent time in the open ocean before entering the less salty water of coastal areas. He can basically tell where fish are spending their time at any given stage of history.

In the case of the Atlantic croaker, a popular saltwater food fish, Thorrold and his assistant have successfully followed the travelling of young fish from mid-ocean to the coast, a journey of many hundreds of miles.

This is important to managers in the fish industry, who know nearly nothing about the whereabouts of the young fish for most food fish in the ocean. Eager to learn about his technology, fish scientists are now lending Thorrold their ears.
