Young Scientist Challenge


All of us have taken a science class at one time or another. Some recall science with feelings of excitement, wonder and awe. Some continue their studies in science throughout the rest of their education. And some even take their love of all things science and make a career out of it. But for many, science is not a happy subject. Do you think back to studying science and get a feeling of dread, anxiety or fear? When did you lose interest in science -- sometime around middle school? Well, you're not alone.
­Studies have shown that an interest in science is either piqued or lost in middle school. Think back to that time in your life. It probably wasn't the best time, was it? That time is full of awkwardness, pain and peer pressure. At that age, children begin to really grow and mature. And in doing that, they begin to find out what they're really interested in. But children are also extremely impressionable, and their friends may not like the interests they're developing. Let's face it -- science and math aren't the most glamorous subjects around, and kids don't want to seem uncool. So they give up science and move on to study other things. But those kids who give up science and math miss so much that it's nearly impossible for them to catch up to their peers. So educators are taking a proactive stance and doing everything they can to keep interests high -- they want science and math to be cool again. Science And Maths Still Rocks...

The Interesting Theraphy

Gene Theraphy


Gene therapy is a rapidly growing field of medicine in which genes are introduced into the body to treat diseases. Genes control heredity and provide the basic biological code for determining a cell's specific functions.

Gene therapy seeks to provide genes that correct or supplant the disease-controlling functions of cells that are not, in essence, doing their job. Somatic gene(body gene) therapy introduces therapeutic genes at the tissue or cellular level to treat a specific individual. Germ-line gene therapy inserts genes into reproductive cells or possibly into embryos to correct genetic defects that could be passed on to future generations. Initially conceived as an approach for treating inherited diseases, like cystic fibrosis and Huntington's disease, the scope of potential gene therapies has grown to include treatments for cancers, arthritis, and infectious diseases. Although gene therapy testing in humans has advanced rapidly, many questions surround its use. For example, some scientists are concerned that the therapeutic genes themselves may cause disease.

Others fear that germ-line gene therapy may be used to control human development in ways not connected with disease, like intelligence or appearance(playing God??).

Air Car


Gasoline is already the fuel of the past. It might not seem that way as you fill up on your way to work, but the petroleum used to make it is gradually running out. It also pollutes air that's becoming increasingly unhealthy to breathe, and people no longer want to pay the high prices that oil companies are charging for it. Automobile manufacturers know all of this and have spent lots of time and money to find and develop the fuel of the future.
The search is on baby, but what will this fuel of the future be? Ready-made fuels like petroleum are becoming more difficult to find and automobile manufacturers are turning to greener energy sources like batteries. These batteries can be charged with energy and placed in a car where that energy can be released. As good as that idea might seem, some manufacturers think air could become an even better energy source.



Air? At first glance, the idea of running a car on air seems almost too good to be true. If we can use air as fuel, why think about using anything else? Air is all around us. Air never runs out. Air is nonpolluting. Best of all, air is free.h This is super cool it is not a fantasy. Here's one example :http://dvice.com/archives/2008/02/zero_pollution.php
