This could be the perfect gift for the partner, who embarrasses you on the dance floor. Smart socks, which can teach to dance, may be the answer for anyone with two left feet.
The socks have been developed as a running tool to help runners improve their skills. Thanks to the socks, users can accurately record not only how far and fast they run but also how well. It means the user maximizes their performance, and reduces damage to body and prevents hurt. The hi-tech socks are made of special fibers that watch the movements of your feet. They look, feel and can be washed like normal clothes.
Sensors (传感器) record each movement and send it by an ankle transmitter (脚踝发射器) to a smart phone. Then a “virtual coach” application shows the information and can tell the user what they are doing wrong, and help to improve skill in any task with feet.
The socks should be useful to athletes and weekend joggers. “People think running is so easy and of course everybody can do it but not necessarily safely and well,” Dr. Davide Vigano said. A recent study showed that between 60 and 80 percent of runners got hurt per year. This is pretty much more than any other human activity. Researchers say the technology can also be developed to teach people how to dance, play sports such as golf, or even to help to teach women to walk better in high heels.
Mr. Vigano said, “People could all benefit from the idea. We have had interest from all sorts of sports, like skiing, football, cycling and golf. Anything where you have to use your feet can use it. It could even be put in high heels to help women walk in them safely.”
Socks are just the start, and the technology could be used in gloves, hats and boots. The socks, anklet and software package, are expected to be sold for around￡120, which will go on sale in March.

【推荐1】Scientists have shown a new printing process that can turn just about any piece of paper into a waterproof keyboard that you can fold up and put in your pocket.
The technique uses a special coating that's repellent (排斥的) to liquids and dust, which allows multiple circuit (电路) layers to be printed on top of the paper without any dirt between the layers. On the other side of the paper, standard ink printing can then be used to point out where the buttons are, and what they represent. These layers can be printed in any design you want. What's more, no batteries are required to operate the finished keyboard. It's able to be fully powered from the touch of the operator and the mechanical energy that's produced.
"This is the first time a self-powered paper-based electronic device has been shown," says engineer Ramses Martinez, from Purdue University. When the primed parts of the paper get pressed, they're able to send signals over Bluetooth to another device—a laptop, for example. You've then got a lightweight, foldable keyboard that can be taken anywhere and easily wiped clean when needed.
The technology is great. It's good for the environment because the paper can be simply recycled again. These paper devices are cheap to produce as well - less than $0.25 each, according to the researchers. Potential uses include smart packaging, or where temporary input devices are required.
"I expect this technology to help the user interact with food packaging—checking whether the food is safe to be consumed, or allowing users to sign the package that arrives at home by dragging their fingers over the box to properly identify themselves as the owner of the package," says Martinez. "Additionally, our group showed that simple paper sheets from a notebook can be transformed into music player interfaces (界面) for users to choose songs and play them."

【推荐2】The fireworks that you see are most likely made in China. The country that makes90% of the world’s fireworks is also where they were invented. Most historians believe that the Chinese used firecrackers as early as the second century B. C.
Many countries hold grand fireworks show at their important celebrations. Canadians, for example, put on fireworks show every July 1 to celebrate their own national birthday, as the French do on July 14 to mark the anniversary of their revolution. But the United States of America imports most of the world’s fireworks, spending more than $650 million on them per year. The Walt Disney Co. alone buys about $50 million worth.
A mixture of gunpowder and other flammable compounds(混合物) causes fireworks to explode across the sky in all those pretty colors and fun shapes. Copper, for instance, burns bright blue while strontium(锶) creates deep red. Together, they produce purple. But the outlines fireworks form depend on the placement of these compounds inside their casing (known as the shell), as well as the shape of the shell itself.
For centuries the only way to set off fireworks was by hand, but computer controlled equipment came out in the 1980s. Automation means more precisely timed explosions, making the displays more satisfying, not to mention safer.
As you might imagine, setting off fireworks can release harmful substances into the air. For example, a chemical that has been linked to thyroid(甲状腺) problems. “Environmentally friendly” fireworks were developed at the request of the Walt Disney Co. after it received smoke complaints from neighbors of Disneyland. Nowadays, an even more eco-friendly alternative to traditional fireworks is being increasingly adopted: using small aircrafts without pilots to trace flashy patterns in the sky. With them, there’s also a much smaller risk of causing wildfires. The eco-friendly fireworks industry is expected to grow almost 20% between now and 2027.

【推荐3】Although his 1-year-old smart-phone still works perfectly, Li Jijia already feels the need to replace it. “There are many better ones available now. It's time to upgrade(更新)my phone.”
Li’s impatience is shared by many. Shortly after the season when new products are released(发布,发售), many consumers feel the urge to upgrade their electronic equipment, even though the ones they have still work just fine.
As consumers’ minds are occupied by Apple’s newly- released products and debate whether the Google tablet is better than the new Amazon Kindle, it might be time to take a step back and ask: “Do we really need the latest upgrades?”
According to Donald Norman, an American author, “planned obsolescence (淘汰)” is the trick behind the upgrading culture of today’s consumer electronics industry.
Electronics producers strategically(战略性地) release new upgrades periodically, both for hardware and software, so that customers on every level feel the need to buy the newest version.
“This is an old-time trick---they’re not inventing anything new,” Norman said. “This is a wasteful system through which companies--many of them producing personal electronics-- release poor-quality products simply because they know that, in six months or a year, they’ll put out a new one.”
But the new psychology of consumers is part of this system, as Norman admitted, “We now want something new, something pretty, the next shiny thing.” In its most recent year, Apple's profit margin(利润) was more than 21 percent. At Hewlett-Packard, the world’s biggest PC maker, it was only 7 percent.
Apple’s annual upgrades of its products create sales of millions of units as owners of one year’s MacBook or iPhone line up to buy the newest version(版本), even when the changes are slight.
As to Li Jijia, the need for upgrading his smart-phone comes mainly from friends and classmates. When they are switching to the latest equipment, he worries about feeling left out.
“Some games require better hardware to run,” said Li. “If you don't join in, you lose part of the connection to your friends.”

【推荐1】Where do you keep ice? In die freezer, of course. That’s what scientists might have thought when they were looking for a safe place to store ice from mountain glaciers from around the world. They’ve decided to store ice in Antarctica because global warming is causing some of the glaciers in places like the Alps to melt.
Jerome Chappellaz of the French National Centre for Scientific Research is involved in creating an ice vault (地下室) there. He says: “We are probably the only scientific community whose sample (样本) is in danger of disappearing from the face of the planet. If you work on rocks or on tree rings, the raw material is still here and will be for many centuries.”
And why do scientists need to study ice from the Alps, for example? Ice formed on the top of a mountain is made of snow accumulated over thousands of years. Trapped air bubbles (气泡) contain samples of the atmosphere that existed when that ice was formed. Ice is a record of climate. By examining ice, we know carbon dioxide in the atmosphere is higher now than in the last three million years. Researchers use this kind of data to build computer models and try to predict what might happen in the future.
The ice vault will be housed in a snow cave at the Concordia Research Station, which is operated by scientists from France and Italy. The ice samples will be sealed in bags and placed 10 meters below the surface. at a constant temperature of -50℃. This will put the scientists’ minds at rest. Losing the ice samples would be a disaster, and nobody wants to see a mine of scientific knowledge lost forever in a giant pool.

【推荐2】Playing a rhythm-based game for eight weeks helps non-musicians become better at remembering recently seen faces. This suggests that learning to play an instrument could improve short-term memory for non-musical tasks.
There have been several studies showing that musicians tend to have better short-term memory than non-musicians when it comes to music-related tasks, such as remembering musical sequences. It is less clear whether these benefits carry over to non-musical tasks or to non-musicians who are learning to play an instrument, and how these changes might actually be seen in the brain.
Theodore Zanto at the University of California, San Francisco, and his colleagues, randomly assigned a group of 47 non-musicians, aged between 60 and 79, to play either a tablet-based musical rhythm training game, which emulates (模仿) learning to hit a drum in time with a teacher, or a word game for eight weeks.
At the start and end of the eight weeks, participants took a short-term memory test to measure their ability to remember a face they saw seconds before. Only the group who played the rhythm training game showed an improvement on their initial scores of around 4 percent. This suggests, says Zanto, that the rhythm training is improving the brain’s ability to focus attention on a task to get it ready for transforming what you are doing into memory.
The ability to remember and recognise faces tends to decline as we age, so any possible mechanism to turn that the opposite way is important, says Josh Davis at the University of Greenwich, UK. However, the effect demonstrated in this study needs to be shown in real-world facial recognition scenarios as well as in lab-based tests to be completely convincing, says Davis. Theodore Zanto hopes that extending training period beyond eight weeks may lead to a stronger effect on memory recall.

【推荐3】How much sleep do we need? It’s a fundamental question about a basic human function we’ve been practicing for long, but there’s still no simple answer. But whether you’re a morning or evening person could be guided by your genes. That said, your sleeping pattern will change naturally with age, which is also reflected in the National Sleep Foundation recommendations: it suggests 14-17 hours of shuteye a day for newborn babies and only 7-8 hours for over-65s.
But scientists said it’s about more than simple duration. Teens and people in their early 20s do want to go to bed later and get up later too, something researchers suggest might be to do with changing hormones(荷尔蒙). “On average, there’s about a two-hour difference in preferred sleep times of somebody in their late teens or early twenties to somebody in their late 50s or early 60s,” he said. “So asking a teenager to get up at 7 o’ clock in the morning is the equivalent of asking a 55-year-old to get up at five in the morning.”
At the end of the day, the best way to measure how much sleep you each need is to listen to your own body. Do you rely on an alarm clock to wake up? Do you take a long time to feel awake? Are you dependent on coffee drinks to keep you focused during the day? Are you overly impulsive(冲动的) or do you find yourself running a lot of traffic lights, for instance? All these could be signs that you’re not getting enough sleep.
And that, we know today, is bad. The environment can affect your sleep preferences but your genes stay. Scientists said that the understanding of the importance of sleep was “one of the great achievements of modern neuroscience(神经科学),” and that society was moving away from the all-nighter culture to respect the need for sleep.

【推荐1】Only a few people in Toronto have the luck to live within walking distance from their workplace. For the rest of us, commuting (长途上下班) is a rather unpleasant daily necessity.
So how do you avoid a traffic jam in Toronto? You can do it in the old way and listen to one of the radio stations that give regular updates about the traffic situation in Toronto's streets. Seeing the big picture of Toronto's traffic and knowing when and where heavy traffic occurs is a must. From my own experience, there are situations where a quick decision can help you make it in time for an event or a meeting. That's why we prepared three short videos showing the overall traffic situation in Toronto from dawn to night. You can click them and watch.
With the help of "Google Maps", where you can watch the live traffic density all over the world and average traffic data based on past conditions, we are able to provide you with traffic maps for a typical (平常的) Friday.
Friday traffic in Toronto is quite fast in the early morning, with only a few hot spots showing up at the major junctions (交叉点) at 7:00 am. The morning traffic jam starts light at 7:30 and the traffic gradually slows down to reach a breaking point at 8:30. The roads are quite free afterwards, only Allen Road is likely to be jammed around lunchtime from 11:30 am to 12:00. It comes as no surprise that Friday afternoon brings heavy traffic as early as 1:30 pm, mainly on the Don Valley Parkway. You won't have a good time getting away from the city from 4:00 pm to 6:30 pm, as there is a good chance to get caught in a traffic jam. The traffic in Toronto is quite heavy on a Friday night. I hope you will have a nice Friday night in the city and a safe journey home this Friday!

【推荐3】As technology in the security field advances, so does the intelligence of the burglars in prevailing over this technology. Gone are the days when a simple alarm system, connected to your phone line, was enough to protect you from potential security risks.
Cellular alarm systems (蜂窝报警系统)are a replacement of the traditional wired phone line security networks. These systems work just like your cell phone. A cellular module is placed in the main control panel and it sends signals, without the use of wires, to the monitoring station. The cellular signal is sent via the data part of a cellular signal, much like a text message.
Sensors can be placed anywhere in your house. Whenever there is an emergency, the relevant sensor picks up the unusual activity and sends a cellular signal to the main control panel. The control panel serves more than one purpose, which sends a cellular signal at the same time to the monitoring service at the back end. The monitoring service later informs the relevant authorities in the form of high-pitched sirens (高音警笛声). Typically it takes a few minutes for emergency services to arrive at the scene. Depending on the efficiency of your monitoring service and the local authorities, help should arrive soon and deal with the potential threats.
It allows you to monitor your house remotely. All you have to do is simply access the cameras from your phone and keep a check for any unusual activities while you are not around. With cellular technology securing your house, you don’t have to worry about the power failure or even burglars cutting your phone lines.
Since these systems operate on batteries, you should be careful about when the batteries die out. There might be other appliances including microwave ovens and WiFi in the house that can cause disruption (干扰). Ensure that your cellular alarm system's range is not affected by the presence of these appliances. Many homeowners tend to go for wireless systems due to the ease of installation (安装）factor. However，keep in mind that a non-professional installation might actually leave the system easy to damage.

【推荐1】Bees and butterflies are active during the daytime. They get a lot of attention of their roles as pollinators. As these insects have become more endangered, many people have taken action to protect them. But it's a different story for moths. Moths are seen much less often, because they are active at night. They're mainly known for beating against windows when they are attracted by lights. As a result, they are often ignored by humans. But moths also play an important role in pollinating plants.
Last year, scientists studied insects around nine ponds on farmlands in the United Kingdom. They visited these ponds once a month from March to October. The researchers studied three groups of insects: moths, bees that normally work together(like honeybees or bumblebees), and flying insects which work alone, such as butterflies, wasps, hoverflies and other bees.
The bodies of bees and hoverflies are hairy(when you look close enough). Moth bodies often seem furry. All of these insects spread pollen more or less by accident, when pollen from one flower sticks to their bodies and falls off when they move to other flowers.
At the ponds, the scientists caught these flying insects and tried to collect pollen from their bodies. In all, the researchers checked 838 moths, 632 other insects which work alone, and 1548 honeybees and bumblebees. By studying the pollen they collected, the scientists were able to see which plants the moths had pollen from 47 different kinds of plants, including seven plants that bees don't normally visit. The honeybees and bumblebees had pollen from 46 different kinds of plants. The other insects that work alone had visited 45 different kinds of plants.
Richard Walton, who led the study, says that bees usually choose the plants with the most nectar and pollen. But moths are less choosy. There are many different kinds of moths and they pollinate many different plants, filling in the gaps left by the daytime pollinators.
Not only do moths pollinate plants, they also provide important food for birds and bats. But, like many other insects, the number of moths has dropped greatly in the last 50 years, mainly because of pesticides and the loss of natural lands. Just like bees and butterflies, moths are worth protecting. "Moths are not at all less important," says Dr. Walton.

【推荐2】Breakfast is food for the brain and for the rest of your body. And downing those morning calories is worth it, even for people worried about their weight, a new study finds.
The study was led by Marlene Schwartz, a psychologist who studies obesity. Her group studied some 600 middle-school students. Over three years, students from 12 different schools were asked about their breakfasts. Throughout the study about 34 % — 44% of all students said they regularly ate breakfast at home. Up to 17%, or almost one in every six kids, regularly ate breakfast at school. Overall, about one in every 10 kids reported eating breakfasts both at home and at school. Eating habits changed somewhat as the kids got older. For example, fifth graders were more likely to regularly eat breakfast at home. But by seventh grade, 22% of the studied kids often skipped breakfast.
Surprisingly, at every age, kids who ate breakfast were less likely to be overweight. This was true even for those who ate breakfast at home and at school. It also found that students who skipped breakfast most often were those most likely to be overweight. These findings may seem puzzling. Yet Schwartz’s team can think of several possible explanations.
Skipping breakfast may set people up to be “over-hungry” later in the day, she says. Then someone may eat more food than their body needs. When that happens, it might take the brain longer to realize “you have enough food and can stop eating now”. What’s more, not eating in the morning prevents our brains and bodies from working well. It’s very difficult for children to pay attention in class if they arrive without having breakfast.
But why should eating two breakfasts not lead to weight gain? One explanation may be that school breakfasts are very healthy and controlled in size, notes Schwartz. Also, most of the double- breakfast eaters are boys. These kids are active and actively growing. They sometimes eat twice as much as other people.

【推荐3】An estimated 60 percent of cats and 50 percent of dogs in the U. S. are overweight or obese, so chances are that your pet needs to lose weight rather than pack on some pounds. It's not always easy to tell if your pet could afford to lose few, but there are some other signs that can tip you off. One important factor the waist, "Most people don't know what a normal cat should look like," says Romine. "But cats should have waists, too." The vet says you should be able to feel your pet's ribs（肋骨） through its coat, and when you look down at them, they should have an hourglass（沙漏）shape---just like person.
"For some overweight pets, you may want to switch to new food entirely; foods with 'light' or 'healthy weight' labels usually have an increased fiber content to help the dog or cat feel fuller," Romine notes. "Another option is to feed them less of the food they currently cat," Freeman suggests. "Make sure you're reducing table scraps（残羹剩饭）and high-calorie treats like pet biscuits," she says.
It's important to figure out what your pet's ideal weight is as you're helping them to lose. Romine advises working with your vet to get the right number, and if you're following the portion guidelines often printed on food labels, feed them the amount of food associated with the weight you want them to be, rather than the weight they currently are.
Food isn't the only factor that can impact your pet's weight. Romine stresses the importance of exercise in keeping your pet healthy. For cats, just 10 minutes of indoor play each day can make a difference. For dogs, letting them out in the backyard to do their business is not enough. You'll have to exercise with your dog to really get them moving.
