    Scientists have found that human eyes are more likely to be damaged by UV rays while skiing in the snow-covered areas than sitting on the beach, according to a report by the UK newspaper.

    The researchers at Kanazawa Medical University, Japan and American company Johnson conducted the study together. They looked at the effects of light reflection on newly fallen snow on a ski trail in Ishikawa District, northern Japan. They compared the results with the levels of UV rays on a sand beach in southern Japan's Okinawa District.

    They found that on the beach, eyes are exposed to a daily 260 kilojoules (千焦耳) of UV a square meter compared to 658 kilojoules  in snow-covered areas.

The findings are supported by the Japan Meteorological (气象的) Agency. According to the agency, the reflection rate of UV light on beaches is often between 10 and 25 percent, compared to 80 percent in the new snow areas. The amount of light increased 4 percent with a 300-meter rise in height.

    Most of us know that UV rays can harm the skin. That's why we wear sunscreen on our skin before we get out in the sun. But many of us may not realize that UV rays are also harmful to the eyes.

    If your eyes are exposed to large amounts of UV radiation over a short period of time, you may experience a kind of sunburn of the eye, which is harmful. Your eyes will become red and feel a strange feeling. They may be sensitive to light. Fortunately, this is usually temporary and seldom causes permanent damage to the eyes.

    Long-term exposure to UV radiation, however, can be more serious. Scientific studies and researches have shown that exposure to small amounts of UV radiation over a period of many years increases the chance of eye damage, which could lead to total blindness.

    Since we are social beings, the quality of our lives depends in large measure on our interpersonal relationships. One strength of the human conditions is our possibility to give and receive support from one another under stressful(有压力的) conditions. Social support makes up of the exchange of resources among people based on their interpersonal ties. Those of us with strong support systems appear better able to deal with major life changes and daily problems. People with strong social ties live longer and have better health than those without such ties. Studies over types of illnesses, from depression to heart disease, show that the presence of social support helps people defend themselves against illness, and the absence of such support makes poor health more likely.

    Social support cushions stress in a number of ways. First, friends, relatives and co-workers may let us know that they value us. Our self-respect is strengthened when we feel accepted by others in spite of our faults and difficulties. Second, other people often provide us with informational support. They help us to define and understand our problems and find solutions to them. Third, we typically find social companionship supportive. Taking part in free-time activities with others helps us to meet our social needs while at the same time distracting (转移注意力) us from our worries and troubles. Finally, other people may give us instrumental support — money aid, material resources, and needed services — that reduces stress by helping us resolve and deal with our problems.

    I had about 10 minutes to exercise before I had to pick up my two older daughters from school yesterday. It was a busier day than usual for me with a couple of meetings besides my regular work.

    Years ago, I would have put off my workout and would have left things for the next day. But since it was a busy day as well, I knew that I may not have all that much time either. So, I picked up my kettle-bell (哑铃) and went to town for 4 minutes.

    See, 4 minutes, if that's all you've got, is enough to give your body a great fat-burning exercise. How did I get a killer workout in 4 minutes? I used a training workout discovered 10 years ago by a Japanese Sports Scientist called a TABATA.

    It includes 20-second periods of warm-up, followed by 10-second periods of rest and 4-minute straight exercise. How is a 4-minute exercise able to burn fat? It all depends on the quality of work you do. Not on the quantity. Here's how I did it yesterday.

    You should never forget your warm-up. A TABATA workout is 20 seconds of 2-arm Kettle-bell swings, 10 seconds rest, 20 seconds push-ups, and 10 seconds rest. You should do those 4 rounds. That's it. I was done in a total time of 8 minutes by the time and when I got to school my heart was still pumping pretty hard.

    A healthy body is needed for studying and working, and efficiency (效率) is the key to building a great body in the least amount (数量) of time possible and you can't get more efficient than a 4-minute workout.

    It's already challenging enough for environmentalists to keep beaches clear of washed up trash(垃圾) and plastic debris(残骸), but the most difficult problem lies in cleaning up all of the millions of tiny microplastics that are impossible to pick up and separate from the sand.

    Fortunately, a group of engineering students succeeded in developing a massive new vacuum cleaner that can collect microplastics without removing any of the sand from the beach. The 12 Canadian students from the University of Sherbrooke in Quebec built their Hoola One plastic vacuum cleaner as a class project.

    "We did some research and we realized there was no machine around the world to do this kind of job," Hoola One co-founder Sam Duval told Hawaii Public Radio. "So we told each other, 'We will invent it,' and we did it."

    As a means of testing their machine's efficiency, they recently used it on the sands of Hawaii's Kamilo Beach, which is also notorious for being one of the dirtiest beaches in the world. Though their first prototype(原型)experienced a number of technical issues, the students managed to fix the problems and tidy up the beach.

    Using a handheld tube, the machine sucks(吸入)up plastic and sand and dumps them all into a massive tank of water. Since rocks and sand are heavier than plastic, they sink to the bottom of the tank so they can be dumped back onto the beach. The plastic, on the other hand, floats to the top of the tank.

    According to Hawaii Public Radio, the team left the Hoola One vacuum on the island as a donation to the state department- They are now researching the ecological effects of the vacuum on the beach while they search for funding and sponsorships(赞助)to produce more Hoola One vacuums.

Living a healthy lifestyle lies in forming the right eating habits. Here are some of the good habits you can develop when it comes to healthy eating.

Drink plenty of water, you must drink at least 8 glasses of water a day. You may need even more water if you are in a hot environment or if you are exercising.

Eat breakfast. Breakfast is the most important meal of the day. A recent study has shown that those who eat breakfast will use an average of 100 calories less during the day than their colleagues who skip breakfast. They will also be able to concentrate better.

Don't skip lunch. If you do so, your blood sugar level will drop and your metabolism (新陈代谢) will slow down. When you get home you are starving and eat everything you can find.

We all need to snack from time to time, but please choose your snacks carefully. In fact, it's a good idea to eat two healthy snacks besides your three main meals. Choose healthy snacks like fruits, low fat yogurt, cottage cheese with apple sauce.

Eat your fruits and vegetables. We should eat at least 5 servings of fruits and vegetables a day. Take a piece of fruit for a snack, add some bananas and raisins to your favourite breakfast cereal (谷类食物), have a salad of lunch, and eat at least one vegetable at dinner each night.

Do not eat your dinner too late. Try to eat dinner at least 3 hours before you go to bed, this will give your body a chance to digest most of the food before you rest for the next 8 hours. Plan dinner for the week ahead of time and make sure you have everything you need in the house so other family members can get ahead start on dinner if you have a late meeting at the office.
