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.

    A 16-year survey on the arctic Norwegian island of Svalbard found the reindeer（驯鹿）there have declined in weight by an alarming 12 percent. The reduction in average body-mass is being blamed on global warming.

    In research presented lately at a meeting of the British Ecological Society in Liverpool, scientists will explain how rising temperatures are making female reindeer difficult to obtain nutrients during important periods of being pregnant.

    Snow in Svalbard typically covers the ground for eight months of the year, which, combined with low temperatures, limits grass growth to June and July. But as summer temperatures have increased by around 1.5℃, grasslands have become more productive, allowing female reindeer to gain more weight by the autumn and therefore to conceive（孕育）more calves.

    However, warmer winters have brought with them greater rainfall which freezes when is settles on the snow, therefore locking out the reindeer from the life-supporting food below. As a result, female reindeer are becoming starved, causing them to give birth to much lighter young. The average mass of an adult reindeer in 1998, when the survey began, was 55kg, but by 2016 IT had dropped to 48kg.

    Professor Steve Albon, an ecologist at the James Hatton Institute in Aberdeen , said that, because the mammals have a relatively high surface-area-to-volume ratio（表面积与体积比）, they are no particularly energy efficient.

    Reindeer can often access the inadequate food sources beneath the snow by clearing IT away with their antlers（鹿角）, but they cannot break through the hard ice. Without access to the food in winter, calves are being born far lighter than they should be. Numbers of reindeer have also increased rapidly in the past 20 years, meaning that those which are born are facing greater competition for food. “The implication（含义）are that there may well be more smaller reindeer in the Arctic in the coming decades, but possibly at the risk of catastrophic die-offs because of increased ice on the ground,”said Professor Albon Despite the gloomy findings, reindeer appear to be suffering less from the impact of climate change than some other arctic species.

    On Friday, the Food and Drug Administration (FDA) released two proposals to improve food safety. The regulations are a response to a series of recent foodborne illnesses. The FDA hopes these new rules will prevent problems of food in the earliest period of production, before the contaminated（受污染的）food causes consumers to get sick.

    Over the past decade, foodborne illnesses have caused many people to get sick. Food like spinach（菠菜）, ground beef and cantaloupes（甜瓜）has been sent back to producers, because it is bound to contain germs and bacteria that cause illnesses.

    Among the most common problems are dangerous bacteria that cause stomach pains and food poisoning. Often these illnesses occur when food is undercooked or improperly prepared. While not all illnesses are reported, the FDA estimates that nearly 130,000 Americans a year are hospitalized for food-related problems.

    The two new rules proposed by the FDA are called Preventive Controls for Human Food and Standards for Produce Safety. Each rule is described in detail on the FDA's website. Readers can submit comments, which the FDA will use as feedback to mike future adjustments to the proposals.

    The first rule demands manufacturers should have formal plans for preventing contamination and for fixing problems when contamination occurs. This regulation is applied to food produced in the US and overseas.

    The second rule k specific to food that is eaten raw. It requires strict standards of growing harvesting, and packing fruit and vegetables. Workers must make sure the materials used in soil are safe and free of contamination.

    The FDA believes these new rules will not just improve Americans' health but also make a positive economic impact. The regulations can lead to major savings in medical costs for people who get sick because of the contamination food.

    If manufacturers are able to fix problems at source, they will prevent future issuer However, putting the proposals into action will lake lime and money.

Best Inventions

    Sun Power

    People who buy solar panels (嵌板）for their home hope to help the environment and save some money. But they end up with large metal boxes on their roof. Tesla, a car company, solved the problem. The solution is the Solar Roof. It is a series of tiles (瓦) made to look like traditional roofing material while using the power of the sun. Tesla developed it with SolarCity, a longtime provider of solar panels. It is now available to the public.

    Talking Tech

    Echo gives users the ability to talk to their tech. Apple's Siri and Microsoft's Cortana do that too. But in many ways，Amazon's version，Alexa, which is built into Echo，is more powerful. Alexa has grown since it was put on the market in 2014, and today, you can use it to turn on the lights, order a pizza, and more. Echo costs $ 180. Amazon recently developed a junior version, the $ 50 Echo Dot.

    Spin and Roll

    Goodyear is reinventing the wheel. It introduced its Eagle 360 spherical tire (球形轮胎) in March, 2016. The tires allow cars to move in many directions, including sideways, and at angles to handle slippery surfaces. The key is magnetic levitation (磁悬浮). Tires are fixed to cars, but Eagle 360s float beneath them. They're meant for self-driving cars of tomorrow.

    Cycle Safety

    Jeff Woolf had a serious bike crash. If he hadn't been wearing his helmet, he would have been badly hurt. He wondered why so many riders didn't wear helmets. That turns out it was mostly because helmets were big and hard to carry around. Woolf, an engineer, came up with Morpher. The helmet is made from interwoven plastics (交错编织的塑料). It is strong, but it's also flexible enough to fold almost totally flat. That makes it easy to carry. Morpher is priced at $ 119.

                                                                                           Taktak tabulaba?

    You probably don't know how to answer that question ─ unless you happen to be one of the about 430 people in the world who speak a language called Matukar Panau. Then you would know it means “ What are we doing?” Matukar Panau is one of the world's rarest languages. It is spoken in just two small coastal villages in Papua New Guinea.

    Several years ago, David Harrison, a language expert, didn't know much about Matukar Panau either. No one had ever recorded or even studied its words and rules. With so few speakers, the language risked disappearing soon. It was endangered.

    Harrison didn't want that to happen to Matukar Panau. So in 2009, he set out for Papua New Guinea. His goal: use modern technology to help the remaining speakers preserve their native tongue.

    But Matukar Panau is not the only language facing loss. Studies suggest that by the end of this century，nearly half of the 7,000 languages now spoken worldwide could disappear. They're in danger partly because the only people left speaking them are elderly adults. When those old men die, their language will die with them. In addition, children may discard a native language and instead use more common global languages, such as Chinese, English or Spanish.

    In the United States alone, 134 native American languages are endangered. “Language hotspots” exist all over the world. These are places with endangered languages that haven't been recorded. They include the state of Oklahoma, pockets of central and eastern Siberia, parts of northern Australia and communities in South America.
