    At the end of every year, Time picks the best 25 inventions that are “making the world better and smarter”. Here we have picked three of this year's inventions that could be a part of your life in the near future.

The levitating(悬浮的) lightbulb

    This special lightbulb was invented by US artist and scientist Simon Morris. He got the idea of making a lightbulb float from hoverboards(悬浮滑板)，which he used to dream of having as a kid.

    But the floating is not the most amazing part. The rejection force between the opposite ends of the magnets(磁铁)，which were put in the bottom of the bulb and in the wooden base, does the job. What's new here is a technology called induction (电磁感应). It allows the lightbulb to get power from the base even they are not in contact.

Shoes that tie themselves

    They're not what you think-shoelaces that tie themselves in the way we tie them. Instead, the new shoes have small motors that control their laces. When you step in them, your feet will hit a sensor（传感器）in the shoes and the motor will automatically tighten the laces.

    But the shoes weren't just designed for lazy people's needs. They could actually give athletes an advantage during competition. They are also useful for people who cannot move their arms or fingers easily.

The no-touch thermometer

    Taking your body temperature usually means putting a thermometer (体温计) in your armpits (腋窝) and staying still for minutes. It may be easy for you, but it's an impossible task for little kids.

    Now, with the new thermometer, users can simply put it 2.5 centimeters from a patient's forechead and press the button, and it can get the reading in two seconds.

    Some people were eating and drinking in a coffee house. A young woman was sitting alone at a table. She was wearing a beautiful diamond necklace. There was an ugly man at a table not far from her. He was looking at her necklace all the time.

    Suddenly the lights went out. The coffee house was in darkness. The woman started to shout. She was very frightened. A few minutes later the lights came on again. The woman was crying. Her necklace was missing.

    The manager quickly closed all the doors. He telephoned the police. No one could get out of the coffee house. The policemen soon came. The police inspector told his men to search everyone. The necklace was not on anyone. They then searched the whole coffee house. The necklace couldn't be found.

The police inspector then looked at the faces of all the people in the coffee house. He saw the ugly man and looked at the man carefully. He went up to the man and picked up the bowl of soup that was on his table. He then poured the soup into a glass. The necklace fell out. The policemen caught hold of the man and took him away. The young woman was happy to get back her necklace.

    The Internet plays a big part in human life. We use it for work and pleasure. We use it to learn a new language. We find advice on it. We use it to connect with family and friends. We use it to stay in touch with events we care about. The list goes on and on.

    As far as the Internet being a part of our lives. - Well, that train has left the station. This expression means there is no going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, say researchers. A new study finds that heavy Internet use may be connected to high blood pressure (血压) in a young group: teenagers.

    The study results show that teens who spend at least 14 hours a week only may cause high blood pressure, which makes your heart and blood vessels (血管) work too hard. Over time, this extra pressure increases your risk of a heart attack. High blood pressure can also cause heart and other diseases.

    The Henry Ford Hospital in Detroit, Michigan did the study. 335 young people, from 14 t0 17 years old, took part in it. 134 0f the teens were described as "heavy Internet users". And researchers found that out of these 134 teens, 26 had high blood pressure. The researchers say the study is the first to connect heavy web use with high blood pressure.

    The lead researcher is Andrea CassidyBushrow. She said, "Using the Internet is part of our daily life, but it shouldn't ruin us." Ms. Cassidy-Bushrow adds that it is important for teens to take regular breaks from their computers or smartphones and do some kind of physical activity. She also suggests that parents shouldn't let their children use the Internet for more than two hours a day, five days a week.

    If humans pump enough carbon dioxide (CO₂) into the atmosphere, the stratocumulus clouds(层积云) could disappear, and the earth's temperature could climb sharply to heights not predicted in current climate models. It would burn the planet. That's the conclusion of a paper published in the journal Nature Geoscience and described in detail by Natalie Wolchover for Quanta Magazine.

    As Wolchover explained, clouds have long been one of the great uncertainties of climate models. Computer models that easily capture the complexity and detail of most climate systems just aren't powerful enough to predict worldwide changes in cloud behavior. But clouds are important. They reflect sunlight away from the earth's surface. And stratocumulus clouds are those white blankets you might have seen as you looked out the window of arm airplane, rolling out below you and hiding the ground Researchers suspect that certain sudden, past jumps in temperature may have been caused by changes to clouds like these.

    For the new research, scientists modeled just a small patch of sky using a supercomputer. They found that if carbon dioxide levels reach about 1, 200 parts per million(ppm) in the atmosphere, stratocumulus clouds break up. That's a very high carbon dioxide concentration.  Right now, levels have climbed past 410 ppm--a dangerous change from 280 ppm before the Industrial Revolution.

    But humans put more and more CO₂ into the atmosphere every year. If current trends continue, the earth could reach 1, 200 ppm within 100 to 150 years. This could happen if our society doesn't follow through on any of its commitments to reduce emissions(排放), Wolchover reported. And even if it does, the result would be another 8 degrees Celsius of heat added to the global average, on top of the dangerous changes already underway due to greenhouse gases.

    That's an enormous change, and it goes beyond predictions of worldwide ice melt and catastrophic sea level rise. And, once the stratocumulus clouds are gone, Wolchover reported, they likely wouldn't reappear until atmospheric carbon dioxide levels dropped below where they are currently.

    There's still some uncertainty in the data. The 1, 200 ppm figure could change as scientists look into the issue further.

    Better known by his stage name KUN, Cai Xukun is a phenomenon, opening up the music industry in China.

    Last year, after participating in the reality TV show Idol Producer, receiving the most votes from fans, the singer-songwriter rose to fame overnight. At just 21 years old, Cai has topped Chinese music charts with multiple singles.

    On July 26, KUN released his newest single Young. Within just 20 seconds, it reached a million sales.

    KUN wrote the song to share his understanding of youth. He mixed R&B and electronic beats (节拍) to make it more cheerful. A reviewer wrote on QQ Music, "When you listen to the song, you just seem to go back to youth again."

    The song was an early birthday present to himself which he celebrated on Aug 2. KUN also hopes that he always has the courage to pursue (追求) his love of music, no matter what people think. "My works are like my children and I have put my best effort into them." he told the Global Times.

    Indeed, KUN has written and produced most of his songs on his own. "I want every piece of my work to have my own spirit in it," he told music website Soundigest, "I feel more enjoyment when I'm performing my own work."

    Although KUN loves performing onstage, when the lights go down, he prefers to fall back into his own world and darkness at night. "I always get inspired when it's quiet, late at night/' he told I-D magazine, "It's a great moment for me to create new things. Sometimes, I can write songs with a melody (旋律) I heard in a dream."

    To develop his introspection (反思) and find new inspiration, KUN attends different kinds of musical performances — from festivals to opera houses. "I just like to do everything, all for my music, all for my art," he told I-D.

    With such talent and dedication to music, it seems that KUN will continue to make his mark in the competitive Chinese music industry.
