Improving memory is important to success in studying. But is there anything that we can do about it? One solution might be walking backwards.
According to a new study published in the Journal of Cognition, walking backwards, whether doing it really or just imagining it can improve the brainpower in the short term. In the study, 114 volunteers were asked to watch a video in which a woman had her bag stolen. Then they answered 20 questions about the information shown in the video. Ten minutes after watching the video, the volunteers were divided into three groups. The first two groups were told to move forwards or backwards 10 meters while the third group was asked to stay still on the same point. The researchers found that the backwards walking group got two more correct answers on average than the other two groups. This suggests that a relationship between the concepts of time and space is important to the way our minds form memories,
When we walk backwards, everything we learn becomes strange to us. “This forces the brain to think in a different way,” US scientist Christine Weber told Forbes. It almost always means that our brain needs to be more active in the limited time. Naturally, our short-term memory will be improved greatly.
Besides improving our memory, walking backwards also plays an important role in physical health, especially fitness. Another study found that walking backwards puts less strain (压力) and requires a smaller range of movements from the knee joints (膝关节). Thus, there’s less pressure and pain in the knees.
In addition, walking backwards, compared to walking forwards, is more challenging. It requires you to use muscles and movements that you probably seldom use, making it a prefect way to change your exercise routine for greater fitness gains. Meanwhile, by making people put in extra effort, it naturally bums more fat and calories.

【推荐3】All parents know exercise is important for children: It can lower heart risks, control weight and help kids do better in school. Experts have also proved that outdoor activities at an early age can help children form healthy habits for life. But don’t expect kids to understand about those things. Some kids just aren’t into exercise, but that shouldn’t mean they have to be addicted to the TV. So parents could do something to help inactive kids fall in love with physical activity.
If parents sit in front of the TV every night, kids aren’t likely to respect restrictions(限制) you set on their screen time either. So check your own behavior and serve as a role model by putting physical activity into your everyday life. Walk instead of driving if possible. Regularly join in activities that you enjoy and let your kids see how much you enjoy them. In this way, they may “do as the Romans do”. Make sure that children’s fitness is included in the family schedule as well as school, work and shopping. Then you and your children are more likely to stick to an exercise plan. And your children will begin to expect that Sunday morning usually means a hike ride, and on a couple of nights after dinner the family takes a light walk through the neighborhood.
Children who aren’t naturally good at physical activity may be worried about their lack of physical skills and even fear public failure. They need all the support and encouragement from parents. Negative comments don’t work and will only make them feel bad. Remember, focus on the effort—choosing to be active or trying to improve a skill—rather than the result.

【推荐1】Researchers set up an experiment in which 5-year-olds were tested with their fellows under different circumstances of transparency (透明) and different audiences. They set up a sticker machine that in some settings was transparent, and other settings in which only the giver of stickers knew how many stickers he could give. They had children give out stickers in both settings. The results were striking: children were consistently generous only when the receiver and audience of the stickers were fully aware of the donation options. Children were notably ungenerous when the receiver of stickers couldn’t see the options.
The researchers said, “Children only showed consistently pro-social behavior in our study in the condition when they could see the receiver and their allocations (分配物) were fully visible; in all other conditions, children were statistically ungenerous, giving the receiver the smaller amount of stickers.”
They made the conclusions that at a very early age, children are learning how to position themselves socially. Well before they apprehend the sociology of their networks and what social reputation really means, they think strategically about giving as a function of how they can gain a reputation with a peer as a generous citizen or pro-social agent when the receiver observes them.
Children change their behavior in response to having an audience. Help children give to others in full view, delivering meals to families, and in private, dropping off treats or surprises for those who need support without signing their names. Also, children should be reminded that thank-you notes are lovely but unnecessary to receive. When we give gifts or lend help to others, try to help children remember why—to provide something for another. It really doesn’t have to be recognized. When a thank-you card doesn’t come, it doesn’t make a gift any less valuable or meaningful for those who were lucky enough to receive.

【推荐2】Unsolved Mysteries About the Planet Earth
◆Mystery 1: Where did all the water come from?
Water covers 70 percent of Earth’s surface and earns it the nickname “the blue planet”. And where did it come from? The most popular scientific theory states that the water came from several violent asteroids (小行星) filled with ice. Another suggests that the water actually has been around since Earth’s formation. However it happened, though, it’s certainly worked out well for Earth’s life forms.
◆Mystery 2 :What about all the oxygen?
Another thing is the planet’s oxygen. Tiny creatures released oxygen as a waste product, filling the atmosphere with it. After that, the level of oxygen in Earth’s atmosphere went wildly up and down until it finally calmed down around 540 million years ago. Since then, it’s remained at about the breathable level we experience today. But what caused it to be suddenly steady?
◆Mystery 3: What caused the Cambrian (寒武纪) Explosion?
The Cambrian Explosion refers to the explosion of complex life forms that occurred on Earth about 540 million years ago. Before then, life had consisted mostly of bacteria. But at the beginning of the Cambrian period, complex creatures began developing at a rate never seen before. Suddenly, life forms had brains, eyes, and bones. Most living creatures today can trace their blood back to the Cambrian period.
◆Mystery 4: Will we ever be able to predict earthquakes?
We still haven’t been able to come up with a way to accurately predict earthquakes. We can certainly try, but our current technology cannot predict them exactly. We know that earthquakes start when rocks crack underground and send earthquake waves toward the surface, but we haven’t figured out why that happens, or how to predict it.

【推荐3】Despite the common appearing of tablet computers and e-readers, we simply cannot break our addiction to paper. An estimated four billion trees are cut down every year to make paper or cardboard, an energy-consuming process with a vast environmental footprint. Now chemist Yadong Yin of the University of California, Riverside, and his colleagues have developed “rewritable” paper that could help control that impact.
Printed rewritable paper is made using Prussian blue nanoparticles (纳米粒子). The researchers coated conventional paper with nanoparticles of two chemicals: Prussian blue that gives blueprints their characteristic color, and titanium dioxide (二氧化钛), a substance used in sunscreens.
UV light makes the titanium dioxide nanoparticles donate electrons (电子) to their Prussian blue neighbors, shifting its color from midnight blue to milky white.
By shining that UV light through a transparent (透明的) screen marked with black text, the researchers “printed” blue text on a white background. The text lasts about five days and then naturally fades away: “Every morning I could just push a button, and a printer would give me a fresh newspaper to read over breakfast,” Yin says.
The paper can also be reset by heating and reused more than 80 times, a significant improvement over previous types of rewritable paper. “The key advantages are high reusability and stability, easy handling and low cost,” says Sean X. Zhang, a materials scientist at Jilin University in China, who was not involved in the study but has also worked on developing rewritable paper. By comparison, technologies such as electronic ink—used for Amazon’s Kindle Paperwhite—involve moving charged black-and-white particles around, which requires electronics.
Since reporting their invention in Nano Letters early this year, the scientists have used a digital projector to replace their transparent screen. They are now working on increasing the number of times the paper can be reused. Zhang says a key difficulty will be persuading companies to develop the unconventional UV control needed for widespread use. Even though commercialization could be a few years away, Yin says, “We’ve had a lot of discussions with industry investors.”
