Digital technology-email and smart phones especially-have vastly improved workers' ability to be productive outside of a traditional office. Even so, most white-collar work still happens in an office. One reason is that, according to findings of a new survey of office workers conducted by Wakefield Research for the IT company Citrix, most bosses arc doubtful about remote working. Half of the workers say their boss doesn't accept it, and only 35 percent say it's tolerated.

    Skeptical bosses will likely have their doubts reinforced (加深) by the same survey, which shows that 43 percent of workers say they've watched TV or a movie while “working” remotely, while 35 percent have done housework, and 28 percent have cooked dinner.

    It is true, however, that working at home makes people much more efficient (高效的), because it allows workers to take care of annoying housework while still getting their jobs done. It's much faster, for example, to shop for groceries at a quarter to three than to stand in line during the after-work rush.

    The fact that such practices remain officially unaccepted reflects how far we haven't come as a society from the days when we expected every full-time worker to be supported by a full-time homemaker.

    More broadly the Wakefield survey suggests that employers may be missing a low-cost way to give workers something of value. Sixty-four percent of those survey participants who haven't worked remotely would rather give up some bonus in order to get even one day a week working from home. Under such circumstances, smart firms need to find ways to let their employees have enough flexibility (灵活性) to manage their time efficiently.

With more than twenty exhibits of hands-on science and technology and a series of encouraging talks and activities, there's something for everyone. All of our events are free and no booking is required. School groups should let our organizers know ahead of time. Meet the scientists, discover the exciting research and technology they work on and have fun with great hands-on activities.

Opening hours

    The exhibition will be open from Monday, July 2, to Sunday, July 8, 2018. More detailed opening hours will be published here in May 2018.

    A new study says electronic toys are not helping babies learn.

    "Even if companies are marketing them as educational, they're not teaching the babies anything at this time," said Anna Sosa the study's author.

    Researchers listened to audio(声音的) recordings of parents playing with their babies aged 10 months to 16 months. The researchers compared the experiences when the children played with electronic toys, traditional toys such as blocks, or when the children looked at books. What they found is that parents talked less with their babies when the babies played with electronic toys.

    Why is this important? Research shows that how quickly children develop language is often based on what they hear from parents. When the infants played with electronic toys, parents said little to their children. But with traditional toys, such as blocks, parents shared the names and descriptions of the animals, colors and shapes as their children played. There was even more information given by parents as their babies looked at the pictures in books.

    Of course, there is no need for parents to throw out electronic toys, but they should look at their infants' play with such toys as entertainment, not a learning experience.

    Toy Industry Association spokeswoman Adrienne Appell responded to the study. She said it is important that parents make time to play with their children. "Playing is a way that kids can learn so much, not only cognitive(认知的) skills, but social and developmental skills," she said. She added that play should be balanced, including time for just "make believe" activities, as well as traditional and electronic toys.

    Before you were my teacher, I thought that teaching was the last thing I wanted to do. Why would someone want to come in every day and attempt to instruct students, many of whom couldn't care less, or to get paid very little compared with the work he or she put in?

    You may have thought that the only thing I was learning from you was the course, but that's not all l learned. From reference books to funny jokes, you made each class exciting. You always tried to make class charming so that we could be excited about learning. However, those days have gone by.

    Whenever I was confused and needed extra help, you were the exact one to turn to. I would walk into your room for help and there would be several kids. You ran from one student to the next helping each one through their confusion. You could have gone back home after the bell rang. Instead, you chose to Stay and care about what your students did.

    You didn't only care about my learning, but you also cared about other things I was involved in. At the beginning of the year, we wrote down our hobbies and interests. You remembered what we wrote, too. I had missed class for track meets (田径运动会)and when I came back the next day, you would ask me how it went. Many of the teachers never bothered to ask what I liked to do.

    These things showed me the value of teaching. They showed me how much of an influence a teacher can have on a student. I want to be the one that influences students and pushes them toward success. I want students to leave my classroom thinking that their time was worthwhile (值得的). I want to be the inspiration for them that you were for me. Whenever it gets hard for me to continue on this path, I'll remember you and what you did for me.

Have you ever heard of invisible ink? You may have seen it in movies. When light is shone on the paper which invisible ink is written on, you can read it!

As magical as this seems, the change in color is due to science. The ink is absorbing higher energy light and giving lower energy light. This reaction is an example of fluorescence (荧光) .

Light is a very broad term that describes a range of electromagnetic rays, including gamma rays, infrared light (红外光) and ultraviolet light. One part of the electromagnetic visible light is the colors that we can see with the human eye. These rays travel in curvy lines and each type of the ray is characterized by a different wave pattern. For example, Gamma rays have a shorter wavelength than infrared light. Shorter wavelength is connected with higher energy, so gamma rays also have more energy than infrared light.

Corals (珊瑚) are animals that live underwater. And the corals in the Red Sea exhibit fluorescence. Why is this happening? Scientists have shown that fluorescent objects absorb higher energy light and release lower energy light. Since the corals of the Red Sea are deep in the water where there is very little visible light, scientists theorize that these corals absorb ultraviolet light and produce visible light. They have special photo proteins, which enable them to change invisible light to visible light.

Fluorescence is not just used to create pretty colors. Corals have developed photo proteins for a biological reason. The visible light is used by algae (海藻) , which are eaten by the coral, to make food through photosynthesis (光合作用). The visual character of these photo proteins could also be used for biomedical research. They can highlight cells and cell structures under a microscope.

Isn't it amazing that a simple organism that we don't think very much of is not only grand but could also have so many potential uses in medical research!
