To eat only a vegan（素食的） diet might sound difficult, especially with many popular dishes containing meat or other animal products. Yet in 2017, veganism was described as “the fastest - growing lifestyle movement” in the UK, according to BBC news.

    A study by a UK market research organization, suggests that over 542,000 Brits went vegan during the previous decade, an increase of 360%. And the main force behind this increase was those aged 15-34 years old — 42% of recent vegans fall under that age range.

    So why exactly has veganism become so popular among young Brits?

    One reason could be that many young people want to protect the environment, as less meat consumption is known to be beneficial to the environment. Global meat manufacturing is believed to cause 18% of the world's greenhouse gas emissions（排放）, even more than that of all the world's cars, trains and planes combined. Another reason is that many of today's young people believe that it's wrong to kill animals to be used as food.

    Jess Murray, 22, a student at University College London, said that he chose to become vegan after realizing that eating animals is a choice that people make, rather than something that we need to do to survive. “Becoming vegan was an ethical (道德的) decision,” he told the Guardian.

    Social media is also believed to have given rise to the increase in veganism. Platforms such as Facebook allow young vegans to connect with each other much easier, while others such as Instagram have led to the creation of “vegan celebrities (名人)”, who share lips on vegan lifestyles.

    Despite the rising of veganism, Laura Wyness, an expert in diet and nutrition, said that meat is very important for people's health. “A strict vegan diet makes it difficult to get some minerals and vitamins that your body needs,” Wyness told BBC news.

    However, the popularity of veganism doesn't seem to be fading. “It feels more like this is something that is sticking.” said an expert of the Vegan Society, a UK charity that promotes veganism.

    Some places in the world have strange laws. It's important for you to know about them before going there.

    Whoever likes to chew gum(口香糖) may have to leave Singapore. The government really wants to keep the city clean and will fine you for chewing gum.

     Before you leave for the United Arab Emirates you'd better make sure you aren't visiting during Ramadan(斋月). During that time you aren't allowed to eat or drink in public. Tourists have been fined up to $275 for drinking in public.

    Lovers spend so much time kissing each other goodbye at train stations that trains often start late. This law— no kissing your lover goodbye at train stations – is rather old, and isn't in use today in France.

In Thailand it's against the law to drive a car or motorcycle without a shirt on, no matter how hot it is. Punishments are different in different areas and can include warnings and tickets costing about $10. No joke — the local police will stop you.

     Studies in Denmark have shown that cars with their headlights on are more noticeable by other drivers than those with their headlights off. Drivers there are required to leave their headlights on even during the day, or they may face a fine up to $100.

    Do you often buy things using coins? Don't do it in Canada. The Currency Law of 1985 doesn't allow using only coins to buy things. Even the use of the dollar-coin is limited (受限制的). The shop owner has the right to choose whether to take your coins or not.

    Make sure you know about these laws before your next trip. Better safe than sorry.

    Podcasts (播客)

    The B S. Report

    Designed for the sports fan with a sense of humor, the B.S. Report is hosted by the sportswriter Bill Simmons. Simmons show is in very loose and free form and it's not uncommon for him to go almost a whole show without even mentioning sports.

    Wait, Wait…… Don't Tell Me

    One of the most popular Programs on National Public Radio, Wait. Wait... Don't Tell Me is now available as a podcast. The show is a news program in the form of a game show. Each week a group of humorists and writers join host Peter Sagal in Chicago, where they are quizzed on the weeks most important and funny news stories. Listeners also get to call in to play different news-related games for a prize

    The Moth

    The Moth is a weekly podcast run by a nonprofit art organization. The show is made up of recordings of “true stories told before a live audience without notes”. Each week, the group releases short 10-20 minute tales told by people from all walks of life. Past Presenters have included writers, comedians, scientists, and even New York City police officers.

    Film spotting

    Film spotting is a weekly podcast and is a must-listen for any movie fan. The show is focused on movie reviews, but hosts Adam Kempenaar and Matty Robinson do more than just tell their listeners which new movie is worth seeing. They also discuss and examine the film as an art form. The how doesn't just focus on current movies, either, as the hosts frequently discuss old films as part of theme marathons.

    Barbara McCintock was one of the most important scientists of the twentieth century. She made important discoveries about genes(基因) and chromosomes (染色体).

    Barbara McClintock was born in 1902 in Hartford, Connecticut. Her family moved to Brooklyn area of new York City in 1908.Barbara was an active child with interests in sports and music. She also developed an interest in science.

    She studied science at Cornell University in Ithaca, New York. Barbara was among a small number of undergraduate students to receive training in genetics in 1921. Years later, she noted that few college students wanted to study genetics.

    Barbara McClintock decided to study botany, the scientific study of plants, at Cornell University. She completed her undergraduate studies in 1923. McClintock decided to continue her education at Cornell. She completed a master's degree in 1925. Two years later, she finished all her requirements for a doctorate degree.

    McCintock stayed at Cornell after she completed her education. She taught students botany. The 1930s were not a good time to be a young scientist in the United States. The country was in the middle of the great economic Depression. Millions of Americans were unemployed. Male scientists were offered jobs. But female geneticists were not much in demand.

    An old friend from Cornell, Marcus Rhoades, invited McClintock to spend the summer of 1941 working at the Cold Spring Harbor Laboratory. It is a research center on Long Island, near New York City. McClintock started in a temporary (临时的) job with the genetics department. A short time later, she accepted a permanent (永久的) position with the laboratory. This gave her the freedom to continue her research without having to teach or repeatedly ask for financial aid.

    By the 1970s, her discoveries had had an effect on everything from genetic engineering to cancer research. McClintock won the Nobel Prize for Physiology or Medicine in 1983 for her discovery of the ability of genes to change positions on chromosomes. She was the first American woman to win an unshared Nobel Prize.

    The problem of robocalls has gotten so bad that many people now refuse to pick up calls from numbers they don't know. By next year, half of the calls we receive will be scams(欺诈). We are finally waking up to the severity of the problem by supporting and developing a group of tools, apps and approaches intended to prevent scammers from getting through. Unfortunately, it's too little, too late. By the time these "solutions"(解决方案) become widely available, scammers will have moved onto cleverer means. In the near future, it's not just going to be the number you see on your screen that will be in doubt. Soon you will also question whether the voice you're hearing is actually real.

    That's because there are a number of powerful voice manipulation(处理) and automation technologies that are about to become widely available for anyone to use. At this year's I/O Conference, a company showed a new voice technology able to produce such a convincing human-sounding voice that it was able to speak to a receptionist and book a reservation without detection.

    These developments are likely to make our current problems with robocalls much worse. The reason that robocalls are a headache has less to do with amount than precision. A decade of data breaches(数据侵入) of personal information has led to a situation where scammers can easily learn your mother's name, and far more. Armed with this knowledge, they're able to carry out individually targeted campaigns to cheat people. This means, for example, that a scammer could call you from what looks to be a familiar number and talk to you using a voice that sounds exactly like your bank teller's, tricking you into "confirming" your address, mother's name, and card number. Scammers follow money, so companies will be the worst hit. A lot of business is still done over the phone, and much of it is based on trust and existing relationships. Voice manipulation technologies may weaken that gradually.

    We need to deal with the insecure nature of our telecom networks. Phone carriers and consumers need to work together to find ways of determining and communicating what is real. That might mean either developing a uniform way to mark videos and images, showing when and who they were made by, or abandoning phone calls altogether and moving towards data-based communications—using apps like FaceTime or WhatsApp, which can be tied to your identity.

    Credibility is hard to earn but easy to lose, and the problem is only going to get harder from here on out.
