    It is well known that male humpback whales(座头鲸)are skilled singers. Their songs are thought to attract females in high frequency sounds while to compete with other males in low frequency sounds. Research led by the Wildlife Conservation Society has now made a new discovery.

    The study looked at the songs of two humpback whale populations, based on sound recordings collected from 2013 to 2018. One group was based in the South Atlantic, off the coast of Gabon, and the other in the Indian Ocean near Madagascar.  Analysis of the recordings showed that the two groups picked up musical ideas from each other and borrowed phrases and themes into their latest song. This suggested that the males from the two groups came into contact with each other over the five years and shared songs.

    To uncover this musical cooperation, researchers recorded the songs and transcribe them into more than 1,500 individual sounds and patterns, or song units.  They found that the units were composed into larger phrases, which were then repeated to form themes. These themes were sung for hours at a time, or even days. By 2018, both populations have been singing largely the same songs.

    "This similarity in the songs shows that these two populations come into closer contact than other southern populations, explains Dr Melinda Rekdahl, leading author of the study. As well as being an interesting phenomenon, she explains that those songs allow even greater insight into the workings of the humpback whale populations.

    Researchers from France and Italy discovered that Canadian parents are less strict with their children than mothers and fathers in France and Italy.

    “Our most important finding was the difference between Canadians and the others,” said Professor Michel Claes, the lead author of the study. “Canadians focus on independence and negotiation. On the other hand, Italians, for example, exercise more control. We found Canadians seem to focus on negotiation in case of a conflict.”

    Claes said Canada, France and Italy were selected for the study because they share important cultural and social factors. “We chose French­Canadians because they share the same language as France, and originally came from France and share certain values. Italy was included because it was considered to have similar, strong and important family values,” he explained.

    The researchers examined the emotional ties between parents and their children by questioning 1,256 students aged 11 to 19 years old.

    Canadian students reported less control and more free actions, according to the study. Italian parents were stricter and French parents were somewhere in the middle.

    Claes explains that the differences lie in education in Canada, France and Italy.

    “North America has its own educational values, which promote individualization. Tolerance and comprehension are encouraged. Italy, on the other hand, promotes respect of authority, control, and the need for permission.” he said.

    Children from all three countries described their mothers as warm and communicative. Italian and Canadian children had similar feelings about their fathers, and reported high levels of emotional ties. But French fathers were generally thought by their children to be more distant and cold.

    “We were surprised by this,” Claes admitted.“It seems as though the relationships between French mothers and their children were becoming closer over time, while fathers maintain a form of distance and coldness, which is more of a source of conflict in France than in the other countries.”

    More than 135,000 UK drinkers will die from cancer caused by alcohol(酒精)by the year 2035, researchers say. A study by Sheffield University and Cancer Research UK shows that alcohol will cost the NHS (National Health Service)£53 billion over the next ten years including £2 billion on cancer.

    Although alcohol is known to cause many types of cancer including breast and throat, most people don't realize the relation between alcohol and cancer. A survey of 2,100 Britons by the researchers earlier this year found nine in ten did not connect drinking with cancer. The researchers used a computer model to work out the numbers of alcohol-related cancer deaths, hospital admissions(入院)and total costs to NHS over the next 20 years.

    The study shows that a fifth of men and 1 in 10 women have alcohol every day—many of these are middle-aged and middle class. Researchers are very worried about this group as they believe cancer may be caused by drinking over long periods. The study shows that even if the cost stays as it is, alcohol-related cancer deaths will rise from 6,299 in 2015 to 7,097 in 2034. Alcohol will lead to 891,299 hospital admissions, up from 802,118 in 2015, and 65,005 will be caused by cancer.

    Earlier this year Chief Medical Officer Dame Sally Davies studied carefully the alcohol guidance(指导)for the first time in thirty years. She told people there was no safe level of drinking and advised them to drink no more than 14 units a week. But researchers say this guidance isn't enough and want the government to increase a little price per unit of alcohol.

    One day, Mr. Arnold was teaching a lesson, and things were going as normally as ever. He was explaining the story of human being to his pupils. He told them that, in the beginning, men were nomads (游牧); they never stayed in the same place for very long. Instead, they would travel about, here and there, in search of food, wherever it was to be found. And when the food ran out, they would move off somewhere else.

    He taught them about the invention of farming and keeping animals. This was an important discovery, because by learning to cultivate (耕作) the land, and care for animals, mankind would always have food steadily. It also meant that people could remain living in one place, and this made it easier to set about tasks that would take a long while to finish, like building towns, cities, and all that were in them. All the children were listening attracted by this story, until Lucy jumped up:

    “And if that was so important and improved everything so much, why are we nomads all over again, Mr. Arnold?”

    Mr. Arnold didn't know what to say. Lucy was a very clever girl. He knew that she lived with her parents in a house, so she must know that her family were not nomads; so what did she mean?

    “We have all become nomads again,” continued Lucy, “The other day, outside the city, they were cutting the forest down. A while ago a fisherman told me how they fish. It's the same with everyone: when there's no more forest left the foresters go elsewhere, and when the fish run out the fishermen move on. That's what the nomads did, isn't it?

    The teacher nodded, thoughtfully. Really, Lucy was right. Mankind had turned into nomads. Instead of looking after the land in a way that we could be sure it would keep supplying our needs, we kept developing it until the land was bare. And then off we would go to the next place! The class spent the rest of the afternoon talking about what they could do to show how to be more civilized (文明的).

    The next day everyone attended class wearing a green T-shirt, with a message that said “I am not a nomad!”

    And, from then on, they set about showing that indeed they were not. Every time they knew they needed something, they made sure that they would get it using care and control. If they needed wood or paper, they would make sure that they got the recycled kind. They ordered their fish from fish farms, making sure that the fish they received were not too young and too small. They only used animals that were well cared for, and brought up on farms.

    And so, from their little town, those children managed to give up being nomads again, just as prehistoric men had done, so many thousands of years ago.

    Vaping can be just as damaging to your health as smoking. But the minute you kick the habit, you'll feel a difference.

    Vaping is the use of electronic cigarettes-e-cigarettes. Vaping became mainstream in the United States in the late 2000s. When e-cigarettes first hit the market, people believed they were a safer choice to tobacco cigarettes. We now know, however, that vaping, like smoking cigarettes can be quite damaging to your health-and equally addictive.

    Kids and teenagers are especially attracted to vaping, thanks to attractive flavors. Vape use in high school students rose by 900 percent between 2011 and 2015.

    Quitting vaping can be difficult, just like trying to stop smoking. There are some immediate, though often temporary, negative effects. The positive ones soon outpace the negative, however.

    In as little as 20 minutes, your heart rate returns to normal, your blood pressure drops, and your circulation starts to normalize. Your breathing may improve, too.

    Daily e-cigarette doubles a person's risk for a heart attack. If you quit, however, the risk begins to fall very quickly. Also, vaping, like cigarette smoking, can blunt your senses, reducing your ability to smell and taste. After just 48 hours without vaping, you may begin to notice your ability to taste and smell food has improved. Nicotine affects more than your brain: new research suggests nicotine can raise your blood sugar, too.

    Smokers often have a troublesome cough or make a breathless sound when they breathe that many refer to as a smokers cough. Smoking even e-cigarettes can badly harm your lung health and make fighting off infections difficult. Quitting, however, will help your lungs recover. After one month, your lung capacity improves.

    There will come a day when the bad habit of vaping won't have any lasting influence on your body and your health.
