Spring soccer season is under way, and many youth leagues are playing under new safety rules. In November, the US Soccer Federation said that players on its teams who are 10 or younger are no longer allowed to head the ball Players ages 11 to 13 have limits on how often they can practice heading. The new rules are made to prevent kids from getting concussions (脑震荡)—injuries caused by a blow to the head that shakes the brain. Common problems include headaches and dizziness. Severe concussions can lead to long brain damage.
Heading the ball can be one of the riskiest parts of soccer. Sometimes the force of hitting the ball with their heads gives players concussions. But more often, players receive concussions when they accidentally knock heads with other players and hit their heads on the grass. “More concussions happen during the act of heading than any other action in soccer,” explains Dr. Robert Cantu, an expert on brain injuries.
So far, the new rules are made only to teams that are part of the US Soccer Federation. But the group says it hopes other leagues will soon follow its example.
Former US soccer star Brandi Chastain is one of the leaders of the activity to ban heading in youth soccer. She applauds the rule change. Last month, Chastain showed her determination of learning more about the effects of heading when she promised to donate her brain to science after she dies.
“If there’s any information to be gathered on the study of someone like me，who has played soccer for 40 years, it feels like my responsibility,” Chastain told The New York Times.

In a time when ivory poaching (偷猎) has gotten so bad that it threatens to wipe out several animal species, a young Dutch designer is creating “egalitarian (平等主义) jewelry^ made of our very own ivory—teeth.
Lucie Majerus got the idea for her “human ivory” collection after having her wisdom teeth removed. She kept them and soon realized they would make great material for a jewelry collection. “Why wouldn’t we value our own material instead of the precious material from other species? And what if we mine our own ivory and turn it into pearls?” she asks.
Her own teeth became a ring，but in order to create a whole collection, she needed more material, and since having more of her teeth removed wasn’t a very pleasant choice, she asked her dentist to save his patient’s unwanted teeth. Most people choose not to keep their pulled teeth, so they are usually donated to dentistry schools. Majerus also received the lost teeth of two of her teachers at Design Academy Eindhoven, so she had a nice supply of human ivory to experiment with.
To turn human teeth into attractive pieces of jewelry, Lucie Majerus first bleaches (漂白) them, and then uses a stone polishing machine to shape the teeth into various shapes.
Majerus displayed her human ivory jewelry collection at this year’s Dutch Design Week, and claims that people’s reaction was mostly positive. “Surprisingly, most people aren’t frightened at the sight of the jewelry, but really like the idea,” Majerus told Fast Co Design. “Some regret that they didn’t keep their tooth at the dentist and some, who will have teeth taken out soon, are now looking forward to it.”

As young students gain independence, they can take on science and engineering projects that require more special knowledge. The followings are the best educational toys for middle school students.
Terraforming Mars
The goal of the Terraforming Mars board game is to make the Red Planet fit for human habitation. Players, representing a person sent to the planet to warm it, create oceans and build up the oxygen levels, compete for victory points awarded for building cities or introducing animals. The goals are based on real science—for example, players must found greenhouse gas production to warm the planet.

A terrible storm took place in a Friday night. The wind was so strong that many trees were brought down. It is eleven o’clock. Li Ming, one of my best friend, was still not back and his parents were very anxious about them. Half an hour late, the wind stopped，but it was still rainning hardly. Li Ming’s parents were about to look for him then he came home. Li Ming explained that the storm pushed over big trees as well as electricity poles, blocked the roads and that the bridge had washed away by the floods. Therefore, Lei Ming and his classmates had to find another way back. What was even more worse, one of his classmates had a arm hurt. So they took him to the hospital.
