My color television has given me nothing but a headache. I was able to buy it a little over a year ago because I had my relatives give me money for my birthday instead of clothes that wouldn't fit. I let a salesclerk fool me into buying a discontinued model. I realized this a day later, when I saw newspaper advertisements for the set at seventy-five dollars less than I had paid. The set worked so beautiful when I first got it home that I would keep it on until stations signed off for the night. Fortunately, I didn't get any channels showing all-night movies or I would never have gotten to bed.

       Then I started developing a problem with the set that involved static(静电) noise. For some reason, when certain shows switched into a commercial, a loud noise would sound for a few seconds. Gradually, this noise began to appear during a show, and to get rid of it, I had to change to another channel and then change it back. Sometimes this technique would not work, and I had to pick up the set and shake it to remove the sound. I actually began to build up my arm muscles(肌肉) shaking my set.

       When neither of these methods removed the static noise, I would sit helplessly and wait for the noise to go away. At last I ended up hitting the set with my first, and it stopped working altogether. My trip to the repair shop cost me $62, and the sit is working well now, but I keep expecting more trouble.

    Experience around food is about the place. The time and the people, and “the best meal” can be found in a fine dining restaurant or in a crowded street market. How can you recreate that special moment influenced by place and time? Travel is becoming the most popular reason to visit many places around the world. Here are the places that consistently excite the senses.

    South of France

    Markets with fresh fruits and vegetables and butcher shops are abundant. Regional(地区的)wines are excellent. And freshly baked French bread with French butter is what memories are made of. Take a chair in an ancient walled city for a meal with a view that you will never forget.

    Barcelona

    This bustling city filled with unique buildings is a city for lovers of history, architecture, and food. Kiosko Universal, a counter restaurant at one comer of the market, prepares some of the simplest and best food we've ever had. Give yourself a week to explore and see everything the city offers. The city is not to be missed.

    Italy

    It's hard to choose one place or city to visit. Some of our favorite places include the coastal regions on the Adriatic and Tuscany. Friuli stole our hearts last year with its many unique wines, small artisan food producers, and influences fro neighboring countries like Austria and Germany.

    Mexico City

    From unbelievable food markets and casual street stands, Mexico City has become the place to travel for the food lovers. If you want to eat locally, order a Hurache, a street food specialty. All you will need is a local microbrew or Mezcal(龙舌兰酒)to wash it down.

    Sound travels very well through water-much better, in fact, than it does through air. So it shouldn't be surprising that many ocean animals make noise. They use sound to communicate and hunt. As biologist Brandon Southall says, “Their whole world is related to sound.”

    Dolphins whistle, organizing hunts. Lovesick whales sing so loudly they can be heard hundreds of miles away. But these days they aren't the only ones sounding off. They have more and more competition from human machines.

    Every day, thousands of huge container ships sail across the world's oceans. On top of the engine noise, the ships' propeller (螺旋桨) make a loud noise all the time. All that can make it hard for ocean animals trying to listen out for friends, or dinner. Animals swimming nearby a ship can be deafened or even killed.

    Underwater construction can also be dangerously loud. When construction machines called pile drivers were used during repairs to the San Francisco-Oakland Bay Bridge, dead fish appeared.

    Geologist (地质学家) pound on the seafloor too, trying to find oil wells and map Earth's surface. The results are useful lo science, but all that hammering probably gives ocean animal a headache.

    As people realize how important sound is to ocean animals, they are looking for ways to reduce human noise. Ships could get quieter just by slowing down. Engineers are also trying to find quieter propeller ships.

    Now some companies are using a simple invention called a bubble curtain, which makes sound waves passing through it lose energy and gel quieter. It seems to work - when bubble curtains were fixed on the San Francisco bridge project fish deaths dropped.

    We still have a lot to learn about sound in the oceans, but together we can help keep the sea a quieter place.

    As if 2016 hadn't been hard enough for China's workforce, a yearly survey has revealed that more than half of the country's white-collar employees got no year-end bonus ahead of the upcoming and costly lunar(农历的) New Year holiday. The survey of 11,500 workers by Chinese employment agency Zhaopin found that 50.9 per cent did not get an annual bonus at the end of 2016. Another 9.6 percent were told their bonuses had been delayed until after the New Year holiday.

    Before the slowdown that began in 2014, employers in China had been less ungenerous with cash bonuses, which can total well over a full month's pay and send employees back home for the holiday with plenty of cash for gifts to elders and other family members or to put away as savings. The impact of weak growth on year-end bonuses may have reached the highest point in 2015, however, when 66 per cent of white-collar workers received no year-end bonuses. And the 2016 level actually represents an improvement from 2014, when 61 per cent had to go without.

    But that recovery has also seen the size of bonuses drop: last year the average bonus was Rmb 12,821（$1,861）, about Rmb 2,000 more than that in 2015 but still about Rmb800 below the 2014 average. More than a quarter of those surveyed who saw their bonuses drop last year blamed the drop on poor company performance.

    Differences among the 34 cities surveyed were still greater, as the average bonus of over Rmb 15,800 in Beijing was more than three times than that in the lowest-paying city of Shenyang. Employees of state-owned firms also expressed more satisfaction with their bonuses than those at private companies — and little wonder, as the average bonus at the former was Rmb 17,318, or about Rmb 6,000 more than what private companies' employees could expect.

    But the impact of companies' stinginess(吝啬) can go beyond simply ruining employees' New Year holiday, possibly coming back to affect employers: 39 percent of respondents said they would look for work elsewhere if their year-end bonus was not returned to normal, an increase of 2.3 Percentage points from 2015.

    What's small, buzzes here and there and visits flowers? If you said bees or hummingbirds, you got it. You wouldn't be the first if you mixed the two up. Now a group of researchers even say we should embrace our history of considering the two together in the same group. The way scientists study bees could help them study hummingbird behavior, too.

    Scientists first compared the two back in the 1970s when studying how animals search for food. The idea is that animals use a kind of math to make choices in order to minimize the work it takes to earn maximum rewards. Researchers at the time focused on movement rules, like the order in which they visited flowers, and where flowers were located relative to others .It was “almost like an algorithm（算法）”for efficient searching, said David Pritchard, a biologist at the University of St. Andrews in Scotland. Hummingbirds and bees had similar solutions.

    As the field of animal cognition（认知）appeared, hummingbird and bee research parted. Neuroscientists and behavioral ecologists developed ways to study bee behavior in naturalistic settings. Hummingbird researchers compared hummingbirds to other birds and borrowed methods from psychology to study their ability to learn in the lab. To be fair, hummingbirds and bees differ. For example, hummingbirds have more advanced eyes and brains than bees. Honeybees and bumblebees are social; hummingbirds typically aren't.

    But however they perceive（感知）or process information, they both experience similar information, Dr. Pritchard said. In day-to-day searching for food, for example, hummingbirds may rely on more of a bee's-eye view than a bird's-eye view. Like other birds, they rely on landmarks, distances and directions to make maps when travelling long distances, but they don't use these cues to find flowers. Move a flower just an inch or so away from where a hummingbird thought it was and it will hover over the flower's original location. Dr. Pritchard is investigating if, like bees, hummingbirds engage in view matching — hovering, scanning snapshots of a place to its memory and using those as references later.

    Eating red meat is linked to cancer and heart disease, but are the risks big enough to justify giving up juicy burgers and delicious steaks? Probably not, according to researchers who reviewed data from 12 clinical trials involving about 54,000 people. In a series of controversial papers, the researchers argue that the increased health risks tied to red meat are small and uncertain, and that cutting back likely wouldn't be worth it for people who enjoy meat.

    Those conclusions go against established medical advice. They were swiftly attacked by a group of famous U.S. scientists who took the unusual step of trying to stop the papers from being published until their criticisms were addressed.

    The new work does not say red or processed meats like hot dogs and bacon are healthy, or that people should eat more of them. The team's reviews of past studies generally support the ties to cancer, heart disease and other bad health outcomes. But the authors say the evidence is weak, and that there's not much certainty meat is really the cause, since other diet and lifestyle factors could be at play.

    If the latest example of how divisive nutrition research has become, with its uncertainties leaving the door open for conflicting advice. Critics say findings often aren't backed by strong evidence. Defenders counter that nutrition studies can rarely be conclusive because of the difficulty of measuring the effects of any single food, but that methods have improved.

    Based on their analyses, the researchers said people do not have to cut back for health reasons. But they noted that their own advice is weak, and acknowledged that they didn't consider factors such as animal welfare and the environment. Indeed, the case that meat production is bad for animal welfare and the environment is stronger than the case that it's bad for human health, according to an editorial that accompanies the report.

    Not all of the report authors agreed with its conclusions. Three of the 14 researchers said they support reducing red and processed meats. A coauthor of one of the reviews is also among those who called for a publication delay.

    Those who pushed to postpone publication also questioned why certain studies were included in the reviews while others were left out.

    As for his own diet, Dr. Gordon Guyatt, a member of the international research team that conducted the reviews, said he no longer thinks red or processed meats have significant health risks. But he said he still avoids them out of habit, and for animal welfare and environmental reasons.
