1 . We know it can be hard to put your phone to bed before you sleep. However, if you’re trying to improve your sleep, you really should ditch your phone at least an hour before bedtime. Luckily, our experts can help.
Scientific evidence suggests that the blue light emitted from your phone, tablet, computer, and TV suppresses (抑制) your body’s production of melatonin, a hormone (荷尔蒙) that plays an important role in your sleep cycle. Melatonin release in the evening helps you relax before bedtime. A 2013 study that analyzed technology use and sleep patterns with data from a National Sleep Foundation poll found that using devices like phones was tied to more sleep disruption than electronics that aren’t interactive.
Many of us use the excuse that our mobile devices serve as our wake-up calls, or keep them nearby to use meditation apps. If you want to use your phone as an alarm, consider setting it a couple of hours before you turn in for the night, and then setting the phone itself to bedtime mode for the rest of the evening.
Here’s another groundbreaking idea: You could get a real alarm clock. After reviewing them at Reviewed, we recommend the Sharp Dream Caster. Not only is it easy to set a wake-up time, the clock includes white noises and rain noises to help you sleep, plus a number of volume settings to pick what works best for you.
But an alarm clock won’t help you avoid doom-scrolling through social media. Take things a step further by avoiding using electronic devices. You can try reading a book (one made of paper), taking a bath or drinking a cup of chamomile tea.
Finally, if you want to keep up your meditation practice screen-free, consider the Morphée. It looks like a little music box and comes with a variety of breathing exercises and soundscapes to help you get to sleep.

3 . Handing your baby a phone or a tablet to play with may seem like a harmless solution when you’re busy, but it could actually affect their development, a new study has found.
Having anywhere from one to four hours of screen time per day at age l is linked with higher risks of developmental delays in communication skills, fine motor skills, personal and social skills,and problem-solving skills by age 2, according to a study of 7,097 children published in the journal JAMA Pediatrics. The study measured how many hours children used screens per day at age 1 and how they performed in these developmental domains (领域) at ages 2 and 4. Both measures were according to the mothers’ self-reports.
By age 2, those who had had up to four hours of screen time per day were up to 3 times more likely to experience developmental delays in communication and problem-solving skills. Those who had spent four or more hours with screens were 4.78 times more likely to have underdeveloped communication skills,1.74 times more likely to have poor performances in fine motor skills and two times more likely to have underdeveloped personal and social skills by age2. By age 4, risk remained only in the communication and problem-solving categories.
“One of the areas that is relatively understudied in the whole screen time literature is looking at the impacts of screen exposure on very young kids, especially when screens are introduced to babies,” said Dr. John Hutton, an associate professor of general and community pediatrics (儿科) at Cincinnati Children’s Hospital Medical Center. “It’s definitely a global concern, and I think the findings should really be applied to other countries as well.”
“Technology use can take time away from interpersonal relationships that develop social skills since real people are more multidimensional than characters on a screen.” Hutton added. Looking at people’s faces is when our brains turn on to figure out how to interact with them.

4 . Four Interesting Science Museums
Polytechnic Museum, Russia
For many guests of the capital, some of the most vivid childhood memories are associated with this museum. A variety of technical fields are presented in 65 halls-Mining, Space, Energy, and Transportation, etc. And the exposition（博览会）is the only museum project in Russia about the history of the bike. The interactive division "Technoplay" is open, where you not only can but also need touch most of the exhibits with your hands. In addition to self-experimentation, for personal requests the museum's experts will show many entertaining experiments.
Eureka, England
The Eureka educational center is a huge complex where modern science and technology are becoming clear, even to kids. The main exhibition is devoted to the human body, the laws of physics and natural things. Visitors can obtain energy or create paper with their own hands. On the area of the Eureka educational park there is a botanical garden and a collection of minerals from the rock types of Finland is presented there.
Deutsches Museum, Germany
In this museum you can see more than 100 thousand different items from windmills（风车）to medical equipment. All aspects of industrial production appear before the eyes. Several museum rooms are arranged especially for children-there are exhibits that entertain kids starting from three.
NEMO, the Netherlands
The largest Dutch research centre stands ready to share its secrets with everyone. This immersion（沉浸）in the world of science and technology will not be dull. All significant information is presented in the form of exciting games. All exhibits are interactive; visitors are allowed to touch, pull and press on anything. The museum is for children from 6 to 16, as well as for their parents-it will be interesting to all.

7 . We have a real crisis in this country in the basic understanding of science. It affects our global competitiveness as a country, our national security, and the effectiveness of our social system. The misunderstanding about science is blinding our eyes.
We know that an awful lot of teachers who are teaching science today have not been properly empowered to do so. School frequently isn’t testing whether you understand something but whether you’re familiar with it. What’s Newton’s second law? You say F=ma, and you get an A. That does not reflect a deep understanding of Newtonian mechanics. Science education is not just a body of facts; it’s a process. To present it with appeal and excitement you need to picture it as a detective story—asking questions, making observations, and collecting evidence. You test and you fail but, you know, failure can lead to discovery.
Another challenge we face is that science is often viewed as too hard, for experts only. But I don’t actually think it’s that difficult. People see science every day. They look outside and see weather and nature. They push a button in their house and the lights go on. Everybody’s dealing with science every day. They just don’t call it that. And it’s important they do. In fact, science is determining the quality and outcomes of their life.
Science needs creativity. And one of the best ways to be creative is to think “out of the box”. However, we need more courage when we come to practice. Take me for example. Very early in my teens I decided to educate myself. I realized I would never be a very good student because I didn’t like teachers judging me by what I thought were arbitrary (主观臆断的) standards. I decided I’d let the world judge me by whether I could do something of value—solve a problem or build something. That’s why I quit school early and risked everything to start a company. I risked everything I had because I had nothing to lose. I’d rather fail at trying to do something really big than succeed at being medium.
“When’s the right age to think creatively?” you may ask. I’d say in the womb (母腹)! Kids don’t have anxieties about trying to avoid failure. They are full of imagination and much more willing to fail. Just watch a 3-year-old. They touch everything, and if it hurts they don’t touch it again. They learn everything at a breathtaking rate. Start to think out of the box as early as you can, because it’s more likely to take you to places that you can’t predict, schedule and budget for. Do all that when you can bear the insecurity.
