been looking for a \”The idea is that if you find a magical fountain, and drink its water, you will not age.

Researchers in New York did not find an actual fountain of youth, but they may have found a way to turn back the aging process. It appears that the answer may be called the hypothalamus, which is part of your brain. It controls important body activities, including growth, the way we process food and so on.

Researchers at New York's Albert Einstein College of Medicine found that hypothalamus neural stem cells(干细胞)also influence how fast aging takes place.

Dongsheng Cai, a professor at the Albert Einstein College of Medicine, was the leading researcher in a study on aging in mice. He and his team reported their findings.

\speed can be controlled by a particular place in the body, which is the hypothalamus. And it can be controlled by a particular type of cells, which are hypothalamus stem cells.，He adds that when the hypothalamus starts aging, so does the body. So when hypothalamus function is in decline, particularly the loss of hypothalamus stem cells, and this protection against the aging development is lost, it eventually leads to aging.

Using this information, the researchers began trying to activate the hypothalamus in laboratory mice. They did this by injecting the animals with stem cells.

The researchers say the results show that the treatment slowed aging in the animals. \mice aged slowly and they can also live longer.”

But these results were just from studying mice in a laboratory. If the mice can live

It's OK to have ups and downs in your feeling, but having low self-esteem isn't OK Feeling like you're not important can make you sad and can keep you from trying new things. 36 Having strong self-esteem is also a very big part of growing up; as you get older and face tough decisions-especially under peer pressure-the more self-esteem you have, the better.

If you think you might have low self-esteem, try talking to an adult you trust about it.

37 In addition, here are a few things that you can try to promote your self-esteem:

Remember that your body is your own, no matter what shapes, size, or color it is. If you are worried about your weight or size, you can check with your doctor to make sure that things are OK. 38 You should accept and love these things because they are part of you. Remind yourself of things about your body that are cool, like, \strong and I can skate really well.”39 The critical voice inside you will soon lose its power.

Praise yourself every day. Don't just say, \ good about yourself, like, \than I thought I would.” 40 Even if you've got room for improvement, realizing that you're valuable and important helps your self-esteem shine.

A. Remember that there are things about yourself you can't change. B. It can keep you from making friends or hurt how to do at school.
