1 . Israeli researchers say they have created the world's first three-dimensional, or 3D-printed heart using a patient's own cells. They described the experiment as "a major medical breakthrough." Tal Dvir, the lead researcher on the project, said in a statement that it was the first time that human cells had been used with 3D printing technology to successfully create a whole heart. Dvir added that the "printed" heart contains blood vessels which are needed to pump blood. The development marks a step forward for 3D printing in the medical field.
The researchers took samples of fatty tissue from patients. This material was then used to develop “ink” for the 3D printing process. First, the researchers created patches of tissue from the patient’s own cells. Later, they used that same process to create a small version of a whole heart. Using the patient’s own cells is important to reduce the risk that the body’s system to fight infection will reject a transplanted organ.
The goal, the researchers said, is to treat heart disease. The World Health Organization reports that heart disease is by far the leading cause of death worldwide. For patients with severe heart disease, a heart transplant is currently the main treatment available. The researchers hope their invention can help ease the demand for heart transplant donors.
Dvir says that the newly-created heart represents great progress. However, more research and development is needed to produce a fully operating, transplantable organ. One of the biggest challenges for the engineering team will be finding a way to create a human-sized heart.
Dvir said his team planned to transplant heart models designed for animals, possibly within the next year. He added that, for human use, “simpler organs” will likely be produced before hearts. “Maybe, in ten years, there will be organ printers in the finest hospitals around the world,” Dvir said. He hopes such methods will be used “routinely” to produce organs in the future.

2 . Jean was a single mother with a young son. She taught the first grade and worked very hard. She drove a small old car. One August, the teachers returned from a summer break to see Jean drive up to school with three children. The two girls were Jean’s former students who had lost their parents. They did not want to enter a foster care center. They turned to Jean-their first grade teacher-for help. Though she and her son lived in a small house, Jean took the girls in.
During lunch, while other teachers shared life stories, Jean never complained about her new responsibilities. She did, however, speak about her car. With three children to transport, the car was too small and slow. It even burned engine oil. Jean needed something new. However, she couldn’t buy one with three children in her home.
As a good friend, I listened to her concerns. At that time, I did not have much money. But I wanted to help Jean buy a car. An idea hit me when I watched a TV show.
One day, Jean received an invitation to a TV show. She was surprised but decided to attend it. Midway through the show the host called Jean to the stage. He explained he had received a letter, knowing her need for a new car. The audience listened to the details of Jean’s story and were all moved. Then the host said that Jean would receive a new car for her family. Cheers filled the studio and Jean shook with disbelief.
Six hundred miles away, I watched the joy of it all from the television in my living room. Jean’s big heart taught me many lessons that year. I did nothing but share her story.

3 . Coca-Cola is to test a paper bottle as part of a longer-term goal to get rid of plastic from its packaging entirely. The prototype (样本) is made by a Danish company from an extra-strong paper shell that still contains a thin plastic liner (衬垫). But the goal is to create a 100% recyclable, plastic free botte capable of preventing gas escaping from carbonated (碳酸) drinks. The barrier must also ensure no fibers get into the liquid.
That may have a risk of changing the taste of the drink — or potentially can't meet the requirements of health and safety checks. But industry giants (巨头) are backing the plan. Coca-Cola, for example, has set a goal of producing zero waste by 2030. Coca-Cola was ranked the world's number one plastic polluter by charity group Break Free From Plastic last year, closely followed by other drink-producers Pepsi and Nestle.
The Paper Bottle Company, or Paboco, is the Danish firm behind the development of the paper-based container. Part of the challenge has been to create a structure capable of standing the forces exerted by carbonated drinks — such as cola and beer — which are bottled under pressure. On top of that, the paper needs to be mouldable to create distinct bottle shapes and sizes for different brands and take ink for printing their labels.
After more than seven years of lab work, the firm is now ready to host a trial in Hungary this summer of Coca-Cola's fruit drink Adez. Initially, this will involve 2,000 bottles distributed via a local retail chain.
But it is also working with others. Absolut, the vodka maker, is due to test 2,000 paper bottles of its own in the UK and Sweden of its pre-mixed, carbonated raspberry drink. And beer company Carlsberg is also building prototypes of a paper beer bottle.
Michael Michelsen, the firm's commercial manager, says the bottles are formed out of a single piece of paper-fiber-based material to give them strength.

4 . Rosie Dutton teaches a weekly class for 10- and 11-year-olds. During a recent class, Dutton used apples to brilliantly explain the effects of bullying.
Rosie Dutton started out by showing the class two perfect-looking apples. But unknown to the students, she had dropped one of the apples repeatedly on the floor. She picked up the dropped apple and began insulting (侮辱；损害) it.
“I started to tell the children how I disliked this apple, that I thought it was ugly and it was a horrible color,” Dutton wrote. “I told them that because I didn't like it, I didn't want them to like it either.”
They passed that apple around in a circle and the kids joined in on the insults. Then, Dutton took a completely different approach with the other apple.
“We then passed another apple around and started to say kind words to it,” the 31-year-old wrote.
She eventually cut both of them open to reveal that the apple that had been insulted was bruised (青肿的) inside. The apple that received praise wasn't.
“When people are bullied, especially children, they feel horrible inside and sometimes don't show or tell others how they are feeling,” Dutton wrote in her post. “If we hadn't cut that apple open, we would never have known how much pain we had caused it.”
“Unlike an apple, we have the ability to stop this from happening. We can teach children that it's not OK to say unkind things to each other,” the 31-year-old explained in her post. She later added, “More and more hurt and damage happens inside if nobody does anything to stop the bullying. Let's create a generation of kind, caring children.”

5 . Research has shown that 85 percent of communication is nonverbal, so choosing what to wear to an interview is clearly an important part of your overall presentation. It won’t make up for weak answers, but it can communicate some positive things about your personality and what you might be like to work with.
· Blue：You can’t go wrong with darker shades of blue, especially navy. Choosing from this powerful color will project an image of someone who is in control. From the interviewer’s point of view, the color blue suggests calm, stability, trust, truth, confidence and security. These are all great messages to send without saying a word.
· Gray: After blue, gray is the second most popular color to wear for an interview. Like darker blue, it’s not a distracting color to the interviewer, which means they’ll be focused more on what you’re saying and how you’re saying it. Gray means sophistication （老成）, so use it to your advantage.
· Black: This is a commanding color and represents authority. Black also suggests excitement, so use it carefully when putting together your interview outfit. You may want to use it as an accent （着重色） —like in a scarf or tie, for instance—rather than as the primary color.
· Red：This is an extremely powerful color. It’s so strong that you should only use it as an accent color. Reds are associated with energy, passion, desire, power and aggression. People think of intensity （紧张） and passion when they see the color red, so use it carefully or it could send the wrong message to the interviewer.
· White：White shirts and blouses are always appropriate. It sends the message of simplicity, cleanliness, precision and goodness.

6 . The prized love for an ice cream goes back thousands of years, and ice creams were enjoyed by people living all over the ancient world—from China to Mesopotamia.
As early as 4,000 years ago, Chinese people enjoyed a kind of frozen syrup—a thick sweet sticky liquid. Centuries later around 400 B.C., sherbet was a popular treat in the Persian Empire. This cold drink featured syrups made from chemise, quinces, and pomegranates that were then cooled with snow. The modern words “sherbet,” “Barbet,” and “syrup” can find their linguistic origins back Lo Shabbat.
Historic accounts tell of Alexander the Great, who took over the Persian Empire in 330 B. C., enjoying tasty ices sweetened with honey. The Greeks, and later the Romans, adopted the custom of cooling their drinks. In the early yean of the Roman Empire, Emperor Nero was known to apply fruit juices mixed with boney and snow at his banquets. Centuries later in the 1290s, Marco Polo returned from China with recipes for delicious ices, some of which included milk.
Modern ice creams were only made possible by obtaining and preserving snow and ice from cold, mountainous areas or frozen lakes and rivers. Different civilizations created icehouses with variations on the same theme: chambers free of heat and light. Deep pits were often used, and the ice would be packed separately, often with straw or branches, to keep out the heat.
Getting ice was complex and labor-consuming, which made ice highly valuable in the middle Ages, when snow was still brought from the mountains to icehouses throughout Europe. The 17th century witnessed private icehouses, and by the end of the 18th century, large icehouses were built in towns and cities. Traveling sales people sold large blocks of ice door to door.
In some cities the ice trade was regulated by the authorities, who set prices and fines for illegal sale. In Naples there were 43 “ice sellers” in 1807. Rule restricted sellers to supplying ice only during the summer.
Sorbet, sherbet, syrup, or just plain ice cream, these cold, greet treats have been cooling people of for centuries.

7 . What do you think of 80s pop music? Do the names George Michael, Madonna and Michael Jackson sound familiar? Well, these are just some of the names that were well-known in the music scene of the 80s and early 90s. The 80s pop music scene was an important step to the popularity (普及) of present-day music. A new wave in the music scene was introduced, which made such music styles as punk rock, rap music and the MTV popular. Although it was an end to the old 60s and 70s styles, it was also the beginning of something big. The popularity of music videos meant that artists now replaced their guitar-based music with visual displays. A new wave of artists came on the scene and the entire industry developed quickly.
The most famous 80s pop music video is Michael Jackson’s Thriller. Introduced in 1982, few people can forget the video not only because of its never-be-foreseen images, but also because of the popularity it received. Think of how 80s pop music changed the lives of people who grew up in the 80s. Ask a young man today to tell you the names of the “New Kids on the Block” and he will start talking about the neighbor kids who just moved in. These are not the answers you might have heard in the 80s. Though today’s young men do not recognize how cool 80s pop music was, most people will always remember it for what it was and these are happy memories they will always love.
Some of the 80s pop music legends (传奇人物) include Madonna, U2, AeroSmith and of course the King of Pop Michael Jackson. Let’s not forget Prince, Tina Turner, Phil Collins and Motown’s Lionel Ritchie. Some of these musicians played music that has stood the test of time. Undoubtedly, the 80s pop music scene will live on for many more years to come.

8 . When you're struggling to finish a term paper, preparing a big presentation or studying for final exams, sleep might be the first thing you sacrifice so you have time to get all the work done. To make up for it , you might start drinking coffee to help you study late into the night. But there's bad news if you're trying to keep that kind of schedule for more than a couple of days.
"We were particularly surprised that the performance advantage invested by two daily 200-milligram doses (剂量)of caffeine was lost after lack of sleep for three nights, " lead author Tracy Jill Doty said in a statement. "These results are important, because caffeine is widely used to deal with performance decline following periods of lack of sleep. The data from this study suggests that the same effective daily dose of caffeine is unable to prevent performance decline over many days of lack of sleep. "
The sample size was very small (48 people), so we can't think everyone will respond the same way. Those 48 people slept five hours per night for five nights straight. They got a caffeine dose equal to a large cup of coffee around 8 am and another around 12 pm each day. For the first two days, the people who got caffeine were performing better on attention and reaction tests. But by the third day, the caffeine was no longer helping them perform any better than the people who didn't get any caffeine.
Increasing the caffeine dose may have changed that. "But the more caffeine you consume, the more negative side affects you feel," Doty said. "This work goes along with lots of other work showing that the negative effects of lacking sleep are difficult to overcome. This is true even with a heavy daily dose of caffeine.

9 . Things changed for Ben Southall when the Australian state of Queensland advertised a job for someone to look after Hamilton Island in the Great Barrier Reef. They knew it sounded like the best job in the world, but they were surprised when over 35, 000 people applied for the job. Then they had to make a difficult decision—which person to choose from so many candidates? After a lot of testing and interviewing, they announced 34-year-old Ben Southall from England as the winner. Ben now works for the Queensland Tourist Board and his job is to look after the island and to promote tourism there. Because of the unique nature of the job, the Tourist Board wanted a unique person, with a range of skills and qualities. It was a long interview process, involving a variety of tasks to find out about each candidate.
Fitness was very important; swimming ability was particularly essential. Ben can swim very well and he also likes running, climbing, diving and mountain biking. It is clear that, physically, he can do almost anything. The ability to communicate was as important as fitness. For the last part of interview process, the final sixteen candidates did various tests and tasks, including talking to TV and radio reporters. The competition was tough and the candidates needed to show what they could do. The interviewers were interested in how the candidates performed in the tasks, how they handled the press attention and their ability to write about their adventures in a daily log. The candidates did their best to impress the interviewers and they knew they couldn't make any mistakes at this final stage.
Before he went, Ben was confident about his abilities to handle the challenge. He couldn’t do everything they asked him in the interview, as he can’t speak any other language but he felt that his other skills and his personality were impressive. He made a huge effort during the interview process and he was able to convince the interviewers that he was the best person for the job. Even so, he says he was amazed when he got the job; he couldn’t believe it! He hopes to do a good job and promote the island successfully: he has to get to know every part of the island and tell the world about it in numerous media interviews. When you read Ben's blogs from his interview tasks, it is easy to see why they chose him. He is funny and easy-going and he will certainly get the attention of any potential tourist to this beautiful place.

10 . The door of a small cage opens up and a bird flies into a large enclosure (围场). The bird lands on a tree and moves its red head to the side, as if it is surprised. “That’s what it feels like to be free,” said Juan Camilo Panqueba, who works at a wildlife center in the Colombian city of Bogota, far from the Caribbean coast, where the bird usually lives.
Birdsong contests have taken place all over the Caribbean for hundreds of years. Although catching any wildlife is not permitted by the law, wildlife trafficking (非法交易) still happens a lot in Colombia, as the officials were too busy fighting with the drug trade, nongovernment fighters and other dangerous groups. Until recently, they did not enforce (强制实施) the law. Now, as dangerous groups have fallen and with the drug trade mostly destroyed, officials are taking another look.
Three weeks ago, Colombian officials saved birds from a group. The group was mostly people who had recently moved to Bogota from the Caribbean and Venezuela. Officials accuse (控告) the group of setting up a songbird competition on social media. In a closed Facebook group, crowds cheered and recorded the loudness and the number of calls from each bird. The owner of the winning bird received＄100, and people who correctly predicted the winner could also win money. Environmental officials say the birds were badly hurt, because they were kept in the small cages and forced to listen to loud music all day long to make sure they can sing. In the wild, the birds sing to protect themselves or find a mate. “For them, it was like cruel harm,” noted Juan Camilo Panqueba, who works at Bogota’s wildlife center. There, he and others care for birds and more than 1, 000 animals.
Colombians have grown to understand the importance of wildlife, and officials are working to end animal trafficking.
