Different from common belief, blue light may not have a strong negative effect as people thought-according to the scientists from the University of Manchester.
It's known that our body clock measures brightness through melanopsin(黑素蛋白),a specialized light sensitive protein in the eye. So there has been lots of interest in studying the influence of light on the body clock. Researchers changed the make-up of short and long wavelength light, which provided a small difference in brightness, as well as changes in color. Findings suggested blue light might be troublesome to our sleep patterns.
The new research, however, used a different method, since the changes in color may oppose the benefits from reducing the brightness signals detected(探测)by melanopsin. The team used specially designed lighting to change color without changing brightness.
Findings of the new research showed that blue colors produced weaker effects on the subjects' body clock than equally bright yellow colors. "Our recognition of color comes from the retinal cone cells(视网膜锥形细胞),and the blue color signals they supply reduce the influence of light on the body clock," explained the lead researcher. "The research shows the common view that blue light has the strongest effect on the body clock is misguided.”
According to the team, using dim(昏暗的),cooler lights in the evening and bright warmer lights during the day may be more beneficial to ensure healthy patterns of sleep. Twilight(暮光)is both dimmer and bluer than daylight and the body clock uses both of those features to decide on the proper times to be asleep and awake.
The findings have important suggestions for the design of lighting and visual displays which aim to promote people's sleep patterns. Present technologies are mostly designed to limit our evening exposure to blue light by changing the screen color of mobile devices. The technology, however, may send the body clock mixed messages. This is because the small changes in brightness they produce come along with colors that are commonly seen during the day. So there's more for the designers to take into consideration.
Setting our body clocks in line with our social and work schedules can be good for our health, and using color correctly could be a way to help us better achieve that.

2.According to the new findings, what should the designers take into consideration?
A.The changes in both colors and brightness.
B.The influence of the daylight on sleep patterns.
C.The suggestions on the proper use of mobile devices.
D.The balance between technologies and the body clock.
3.What can we learn from the new research?
A.Blue light cannot he easily detected by the body clock.
B.Blue light has the weakest effect on people's body clock.
C.Blue light is not as harmful to their sleep patterns as people thought.

If you are given only 1 yuan, could you live in a city for one day? It seems this may be a little difficult. But students from Xi' an made it.
On April 10, more than 60 students from the Middle School Attached to Northwestern Polytechnical University took part in the One Yuan Metropolis Survival. 1. Students not only had to live, but they also had to deal with a lot of hard tasks.
2.为了赚钱,无论走到哪里,许多学生努力找寻兼职工作。 In this way, they also saw how hard life was. Zhang Qiyue, 14, asked more than 10 restaurants for a job and finally got one chance. We were upset when they said no. But gradually, we got used to it, he said. After being a waiter for an hour, he got 25 yuan. 3.他们甚至通过在公园唱歌跳舞来赚钱。
Living was hard, but finishing the tasks wasn't any easier. 4. They went to different places to finish tasks in a short time. The most amazing one was when they had to exchange things worth thousands yuan with only a piece of paper in half an hour. "We learned how to persuade others. From a balloon to a cake to a bottle of yogurt... after almost 20 tries, we got an expensive necklace( 项 链 )," he said. 5. They will give all of the money they made to poor schools in Tibet(西藏).
