If you're planning to go on a diet o1 if you suffer from serious conditions like diabetes( 糖尿病), knowing exactly what and how much you're eating is essential. In this day and age, we have calorie and nutritional calculators even on our smartphones, but they act only as guides, whereas Panasonic's revolutionary new device, CaloRieco, actually analyzes the food on your plate and provides accurate in formation about in just a few seconds.

    You've probably used calorie calculators before,and you know that they only offer general information. For example, a calculator will tell you the average number of calories in a hamburger, but it can't tell you exactly how many calories are in the hamburger. The same goes for nutrients like protein or fats. And this is what makes the new CaloRieco so special.

    Displayed at a recent tech show, CaloRieco is a high-tech device that uses light reflection technology to determine the nutritional values of almost any food and also provide accurate calorie estimates.All you have to do is put your plate in the box-shaped device and wait between 10 and 20 seconds for it tc analyze all the food on there.

    Once it's done analyzing the various ingredients(原料)in your meal, CaloRieco displays the number of calories, as well as the nutritional content on an LED display, According to Panasonic, the device is able to recognize the vast majority of foods, except soups and very dark dishes.

    CaloRieco can also connect to your smartphone via an app, and send all the data about analyzed foods to your handheld, so you car access it whenever you need.

    Panasonic said that its outstanding invention is aimed at dieters and diabetes sufferers, both of which make up a large market.Unfortunately,you'llhave to wait a bit longer to your hands on your very own CaloRieco, as the device presented a the show is just a prototype(样品) which needs to be improved. It 's scheduled to hit the market sometime in the next few years, but the price remains unknown.

    How do the world's only flying mammals communicate? Researchers have observed young bats adopting new “dialects” simply by hearing them repeatedly, making them one of the few animals known to have a capacity for vocal (声音的) learning. “These bats may help us clarify the evolution of speech acquisition (习得) skills,” says Yosef Prat, a PhD at Tel Aviv University (TAU).

    For one year, researchers raised 14 Egyptian fruit bat pups with their mothers in controlled area, exposing each young bat to two different vocalizations: the natural call of its mother and a separate recording that varied in pitch (音高) or frequency. They found that the pups in each group developed a dialect like the recording. “The general assumption in this field is that most animals develop their born vocalizations regardless of what they hear, and that human vocal learning abilities have developed during evolution,” says Mr Prat. “The finding that bats learn the common dialect in their rest place was unusual.”

    Scientists know little about the origin of spoken language, which is believed to have appeared in humans within the past 500,000 years. Dozens of theories attempt to explain the complexity of this skill, but none have done so conclusively.

    “Studying vocal communication and vocal learning in animal models is a very useful way to approach the problem,” says Olga Feher, an assistant professor at the University of Warwick in England.

    But animal vocalizations and human speech are very different things, says Jamin Pelkey, a professor at Ryerson University. “All species communicate. Unlike other animals, though, human beings are able to use sound patterns for functions that are far stranger—functions that are imaginative, theoretical, and critical. When speech is involved in these stranger functions, that is what we mean by spoken ‘language'.”

    Who can think of the race between the tortoise and the rabbit when it comes to the greatest races? Sure, that race only took place in ancient Aesop's mind, but while the great modern races can teach us a lot about commitment, perseverance (毅力) and the virtues of having a rather large engine, "The Tortoise and the Rabbit" may tell us everything about animals and even vehicles on this planet.

    In a study published this week, Adrian Bejan, a professor of mechanical engineering, concludes that no one should be surprised that the tortoise wins over the seemingly speedier rabbit. In fact, after analyzing the reported speeds of land-air-and-water-based animals, Bejan concludes that the world's well-known speedsters are actually among the slowest when their movements are averaged out over the course of a lifetime.

    The study builds on Bejan's previous research showing that an animals speed increases with mass regardless of species. And that principle can also be extended to non-living things, like aircraft.

    After studying data from historical airplane models, Bajan noted the speed of each model increased with its size, too. That doesn't sound right. What about the modern jet fighter? How is that relatively small craft not faster than a clumsy large transport plane?

    Again, Bejan harks back to the tortoise. That transport plane spends lots of time in the air, moving regularly across long distances. The fighter jet, on the other hand, may fly across the sky occasionally, but-like the rabbit-it's often found resting on the ground.

    The slow and steady transport plane wins the marathon of life.

    But like so many good stories, Aesop's tale offers even more than a lesson in perseverance.

    At one point, the rabbit asks the tortoise how he expects to win a race at such a slow pace.

    The tortoise—ever focused—doesn't respond But it's the rabbits own words that provide the moment to reflect on, especially in modem times.

    "There is plenty of time to relax," Until there isn't.

    There was once a man who had a donkey and a beautiful lapdog. The donkey was kept in a barn and had plenty of corn and hay to eat. Indeed, he was just as lucky as any donkey could be. The little dog stayed in the house and was well liked by the master. He was always playing and jumping about in an funny way and was allowed  to lie in his master's lap (膝盖). Meanwhile, the donkey had plenty to do. He pulled wood all day long and had to take his turn at the mill during the night. He often complained about his problems, and it bored him to see the lapdog living such an easy life, while he had to work so hard. Finally he thought to himself that if he acted the same way as the lapdog to his master, he would be treated the same way. So, one day he ran out of his barn and went fast into the house, where he began to kick about in a very strange way. Then, swaying his tail and imitating the funny behavior of the pet lapdog, he knocked over the table where his master was eating. He also broke all the dishes into very small pieces and did not stop until he jumped onto his master, trying to lick and paw him with his rough feet.

    Seeing their master in great danger, the servants thought it was time to help him. They beat the foolish donkey with sticks until he could not get up again. As he was about to die, he cried, "Why couldn't I have remained satisfied the way I was? Why did I try to imitate a creature who was nothing but a lazy puppy after all?"

Cheerfulness is a powerful way to deal with a world that will always be tough and unjust in one way or another. It is a sign of strength in the face of difficulties. Different from fear, joy, or anger, cheerfulness isn't something that overcomes you.{#blank#}1{#/blank#} As such, you can include it into your life once you make the right mental switch. Here are four ways to do so.

◎Acknowledge the difficulties.

Cheerfulness is an honest emotion because you're not hiding from reality.{#blank#}2{#/blank#} Instead, it's extremely important to be honest with yourself about the problems you're facing. Only by first acknowledging that things are tough will you be able to find ways to cope.

◎ Don't focus on the negative.

Whether in your personal life or in society, it's easy to focus on what's going wrong. But whatever you focus on, it grows. If you decide to focus on what's going wrong, those problems will grow in your mind until they consume you.{#blank#}3{#/blank#}

◎ Be grateful for what you have.

{#blank#}4{#/blank#} Usually, they're the things we take for granted until they're no longer there, such as good health, a loving family, or even something as simple as a beautiful sunrise. Being grateful will shift your perspective and make it easier to see the silver linings of your problems.
