Low speed bicycle crashes can badly injure — or even kill — children if they fall onto the ends of the handlebars. So a team of engineers is redesigning the humble handlebar in a bid to make it safer.
Kristy Arbogast, a bioengineer at the Children's Hospital of Philadelphia in Pennsylvania, began the project with her colleagues after a study of serious abdominal injuries in children in the past 30 years showed that more than a third were caused by bicycle accidents. "The task was to identify how the injuries occurred and come up with some countermeasures," she says.
By interviewing the children and their parents, Arbogast and her team were able tog reconstruct many of the accidents and identified a common mechanism responsible for serious injuries. They discovered that most occur when children hit an obstacle at a slow speed, causing them to topple over5. To maintain their balance they turn the handlebars through 90 degrees — but their momentum forces them into the end of the handlebars. The bike then falls over and the other end of the handlebars hits the ground, ramming it into their abdomen6.
The solution the group came up with is a handgrip fitted with a spring and damping system. The spring absorbs up to 50 per cent of the forces transmitted through the handlebars in an impact. The group hopes to commercialize the device, which should add only a few dollars to the cost of a bike. "But our task has been one of education because up until now, bicycle manufacturers were unaware of the problem," says Arbogast.
The team has also approached the US Consumer Product Safety Commission to try to persuade manufacturers to adopt the new design. A decision is expected later this year.
According to the passage, some engineers are trying to improve the handlebars because
A.they are not noble enough.
B.they may kill children.
C.they are likely to crash.
D.they make the bike move at a low speed.

Sleep Deficit(不足)
Judging from recent surveys, most experts in sleep behavior. agree that is virtually an epidemic of sleepiness in the nation. "I can't think of a single study that hasn't found Americans getting less sleep than they ought to. " says Dr. David. Even people who think they are sleeping enough would probably be better off with more rest.
The beginning of our sleep-deficit crisis can be traced to the invention of the light bulb a century ago. From diary entries and other personal accounts from the 18th 19th centuries, sleep scientists have reached the conclusion that the average person used to sleep about 9. 5 hours a night. "The best sleep habits once were forced on us, when we had nothing to do in the evening down on the farm, and it was dark. " By the 1950s and 1960s, that sleep schedule had been reduced dramatically, to between 7. 5 and 8 hours, and most people had to wake to an alarm clock. "People cheat on their sleep, and they don't even realize they're doing it, " says Dr. David. "They think they're okay because they can get by on 6. 5 hours, when they really need 7. 5, 8 or even more to feel ideally vigorous. "
"Perhaps the most merciless robber of sleep, " researchers say, "is the complexity of the day. " Whenever pressures from work, family, friends and community mount, many people consider sleep the least expensive item on his program. "In our society, you're considered dynamic if you say you only need 5. 5 hours' sleep. If you've got to get 8. 5 hours, people think you lack drive and ambition. "
To determine the consequences of sleep deficit, researchers have put subjects through a set of psychological and performance tests requiring them, for instance, to add columns of numbers or re call a page read to them only minutes earlier. "We've found that if you're in sleep deficit, performance suffers, " says Dr. David. "Shot-term memory is weakened, as are abilities to make decision and to concentrate.
People in the 18th and 19th centuries used to sleep about 5 hours a night because they had ______.
A.no drive and ambition
B.no electric lighting
C.the best sleep habits
D.a lot to of the next day
