As children begin to head back to school, there are several things that you can do to make sure that your child stays healthy and performs at their peak potential during the school year.

    1). Make sure your child is up to date on their immunizations(免疫). The summer is a good time to schedule visits to the doctor's as your child is not in school, and the visit won't require that your child miss school days.

    2).Encourage proper nutrition. America faces childhood obesity(肥胖). This means that the percentage of overweight children is increasing each year, and this will place your child at risk of developing a variety of diseases when they are middle age or even young adults. You can start helping your child to become healthier by offering fruits and vegetables at home instead of calorie heavy potato chips and candy.

    3). Get your child involved in sports activities. Activities in high school such as track and cross-country are important for socialization for your child, as well as helping to improve their health. You can get your child interested in wholesome activities by discussing with them how you enjoyed similar activities in high school.

    4). Have the birds and the bees conversation with your child. Many children become sexually active in junior school and senior high school, and the sooner you discuss sex with your child the sooner they will be prepared. Tell your child that there is always the possibility of infecting a sexual disease when two people have sex; and discuss with your child the use of condoms. The sooner you start having this embarrassing situation the better.

    5). Know your child's friends. You can do this by inviting your child to bring their friends over to your house for a pizza night, or by chatting with them when they stop by your house. If you find your child's friend has a bad reputation, then you could consider introducing your child to a different network of people, such as through the girl/boy scouts. Forbidding your child from seeing a certain person may only lead them to rebel and become closer to that person.

    6). Discuss with your child the seriousness of drug use and abuse. Your child may not realize that using drugs can have serious consequences. Your child may get the false impression that drug use is his right. Explain to a child that saying no to drugs is their right, and that anybody offering them drugs is not their friend.

    7). Help your child to avoid a life long smoking addiction by discussing with them the consequences of smoking. The sad fact is that most smokers became addicted when they were in their teenage years, and are unable to quit for long periods of time and often die many years earlier due to their smoking habit which increases the risk of lung cancer, heart disease, and a variety of medical conditions. Even if you are a smoker yourself, you can discuss with your child about how damaging smoking can be on a person's health.

    8). Impress upon your child the importance of traffic rules. Tell them that it is OK to wear a seat belt in anyone's car, because it may save their life one day. If your child rides a bicycle or a skateboard, then discuss with them the importance of always wearing a helmet. As you child becomes qualified for driver's permit, you should discuss with them the importance of prevention from drinking and driving.

    9). Be cautious about signs of depression in childhood. A surprisingly large number of children may become depressed, and a small number of teenagers and children commit suicide(自杀) each year. Realize that any signs of unusual depressed mood, angry outbursts, suicidal comments, feelings of hopelessness, and loss of enjoyment of activities with friends may be signs of depression.

    Do you want to make a difference in your community? The Verizon App Challenge can get you started. The first step is to think of a problem in your community. The next step is to create an app that can solve the problem.

    Group of five to seven students in middle school or high school, led by a teacher, can enter the contest. First, teams will compete on a local level. Teams that make it to the next round receive $ 5,000 for their schools. Finalists present their app ideas to judges in a live web conference. Next, the judges pick national winners. The top eight teams receive an additional $ 15,000 for their schools, and each team member receives a Samsung tablet. Plus, the winning teams get the chance to bring their app to life.

    A group of six girls from Los Frenos, Texas won the second annual Verizon App Challenge. They came up with the Hello Navi app concept, short for “hello navigation”. The app was designed to help visually impaired (受损的) students navigate (导航) their school. Do you have an app idea that could help solve a local issue? The deadline to register (登记) is November 24. Find more information and register your team at verizonfoundation.org/appchallenge.

Here are some tips from the Verizon Foundation to get you started:

    Get your team together for a brainstorming meeting. Write out all the ideas that conic to mind. Don't ignore challenges. Accept the idea that you can solve a problem that exists in your community. Ask family, friends and people in your community to share their thoughts about problems that they want to see solved.

    Chinese scientists recently have produced two monkeys with the same gene, Zhong Zhong and Hua Hua, using the same technique that gave us Dolly the sheep. These monkeys are not actually the first primates（灵长类）to be cloned. Another one named Tetra was produced in the late 1990s by embryo（胚胎）splitting, the division of an early-stage embryo into two or four separate cells to make clones. By contrast, they were each made by replacing an egg cell nucleus（原子核）with DNA from a differentiated body cell. This Dolly method, known as somatic cell nuclear transfer（SCNT）, can create more clones and allows researchers greater control over the edits they make to the DNA.

    Success came from adopting several new techniques. These included a new type of microscopy to better view the cells during handling or using several materials that encourage cell reprogramming, which hadn't been tried before on primates. Still, the research process proved difficult, and many attempts by the team failed. Just two healthy baby monkeys born from more than 60 tested mothers. This leads to many researchers' pouring water on the idea that the team's results bring scientists closer to cloning humans. They thought this work is not a stepping stone to establishing methods for obtaining live born human clones. Instead, this clearly remains a very foolish thing to attempt, it would be far too inefficient, far too unsafe, and it is also pointless.

    But the scientists involved emphasize that this is not their goal. There is now no barrier for cloning primate species, thus cloning humans is closer to reality. However, their research purpose is entirely for producing non-human primate models for human diseases; they absolutely have no intention, and society will not permit this work to be extended to humans. Despite limitations, they treat this breakthrough a novel model system for scientists studying human biology and disease.

    It's a warm summer afternoon. You're cooking up the catch of the day over a campfire. Suddenly, a few raindrops fall on your arms, and before you know it, the sky is opened up. Then you hear what sounds like thunder in the distance. What should you do? Your tent is close by and would offer shelter from the pouring rain. There's a campsite picnic shelter a few minutes down the path. And then you remember that your car is parked down the road. What's your safest choice to make sure you and your families are safe?

    It's a common question for many hikers(徒步者) and campers, especially when they are camping during summer months. Heading to your car is almost always the safest choice. Your tent and a picnic shelter will keep you dry, but they offer little or no protection against lightening. Your car, on the other hand, will keep you dry and protect you from lightening strikes. Protecting yourself against possible lightening strikes is very important; lightening kills an average of 62 people in the US each year. If you keep all of the windows and doors closed in your car, you'll be able to return to your campsite safely.

    Of course, if you're backpacking(背包旅行), not car camping, and you're deep in the woods, your car won't be a good choice. So, what should you do if your car is far away and there's no other safe shelter nearby? First, you'll have to make sure that tree limbs or other objects don't fall on you or your campsite. Then you'll have to get in a safe position to avoid lightening, or flash flood conditions. What else should you do?

    A lifetime of active exercise will let you keep the body of a 20-year-old well into your 70s, scientists have found.

    The physical decline (衰退) thought to be an unavoidable part of ageing is actually the result of not exercising enough, according to the research, which found that regular cyclists kept the muscles, lungs, and even the immune system (免疫系统) of people years younger. Besides, many serious health problems could be prevented if people became more active, researchers insist.

    Janet Lord, a leading researcher, said, “Our findings prove the false belief that ageing automatically makes us weaker. We now have strong evidence that encouraging people to do regular exercise throughout their lives can solve the problem that we are living longer but not healthier.”

    She looked at 125 cyclists aged 55 to 79 who had been exercising regularly for 25 years and compared them with 75 ordinary people of a similar age and 55 people aged 20 to 36. On a series of physical measures, the cyclists showed no difference from people much younger in their immune systems and making T cells.

    Now Professor Lord aims to discover how much exercise people need to do to stay young. “You needn't work out a lot. It may be intensity (强度) that helps—like going up and down the stairs ten times a day.”

    While there is no magic method of staying mentally and physically fit in later life, the benefits of keeping active can never be ignored, whatever your age or state of health.
