1 . Astronauts traveling in space meet forms of radiation(辐射)that are uncommon on Earth. Some of this radiation has been shown to be harmful to human health. It is linked to cancers and heart problems. Yet a new American study suggests the radiation does not shorten astronauts' lives.
Researchers studied nearly 60 years of health records and other data about male astronauts from the United States. They then compared this data with information about a group of men who are in good health, richer than most Americans and receive good health care-professional athletes. The study found that neither group has higher rates of dying at a young age. In fact, both groups generally live longer than other Americans.
Astronauts are usually well-educated, earn more money and are in better physical conditions than the average Americans Some earlier research has linked being an astronaut to a lower risk of early death, the researchers noted. The findings were reported in the medical journal Occupational&Environmental Medicine.
Much of the existing research on mortality rates(死亡率) in astronauts has not yet explored the mental and physical demands of this job. There also has not been a lot of research on whether astronauts show what is known as the "healthy worker effect". This effect leads people with employment of any kind to have fewer medical problems than people who are unable to work, said Robert Reynolds.
Reynolds said, "The challenge has always been to understand if astronauts are as healthy as they would be had they been otherwise comparably employed but had never gone to space at all. To do this, we need to find a group that is comparable on several important factors."

2 . Age has never been a problem for 16-year-old Thessalonika Arzu-Embry. After all, she’s already got her master’s degree.
The North Chicago-area teen started homeschooling at the age of 4. She began having an influence on others soon after. When she was 6 years old, she was an inspirational speaker at an organization called Tabitha House Community Service, which is for people who were forced to leave their homes because of earthquake, flood and other natural disasters.
At the age of 11, she graduated from high school and then earned her bachelor’s degree in psychology in 2013. She completed those classes online as she was traveling for church events and leadership meetings.
She doesn’t stop there, though. The teen plans to focus on aviation psychology (航空心理学) for her further study, a decision inspired by her father who is a pilot. She grew up around airplanes and took fights all the time. Her goal is to use it to help pilots deal with problems that could have deadly results once the plane takes off — a topic that has been in the news lately. For her, it’s a mix of two of her interests.
In her free time, Thessalonika enjoys playing tennis, swimming and being active in her youth group at church. She also has three self-published books, which are on her site. Jump the Education Barrier is written to help students finish college, and in the future aims to help business owners with trends. Her third book The Genius Race is designed to help people to be talents in various areas of life.

3 . Girls can easily get sad. If your friend is feeling blue and calls you, what will you do? Here are some tips on how you can make her smile again.
Listen to her. When people feel sad, they often have the feeling of needing to be heard. So, listen carefully to what she is saying and do nothing else. Your friend will surely thank you for being the shoulder she can cry on.
Once you are done with listening, you can offer some advice or remain silent and let her feel everything and let it all out by crying. As a friend, you might think you should give her some advice. But if you have no idea about what to say, just remain silent and be there for her.
In order to be able to help your friend in need, don't be sad yourself. How can you help your friend when you are also feeling down.
A hug can make a difference in the world. It makes you feel warm and special. A hug makes you feel safe. So give your friend a hug when she needs it the most.
Spend more time with your friend who wants to be happy. Do things together like washing dishes, cleaning, or going out for fun. The more time you spend together, the stronger your friendship will become.
Sometimes, it is much better that you avoid a crying friend in your life. But by doing so, you are also keeping your friend at a distance and will make her wonder if you are her true friend. If you are there when she needs you, your friendship will be much stronger.
