Expensive perfumes (香水) come in tiny bottles, but many hide a whale-sized secret.

    To perfect a particular smell, perfume-makers often use an ingredient that comes from sperm whales, called ambergris (龙涎香). But using ambergris, which helps a perfume last longer, is strongly opposed by many people who think it is wrong to kill whales just so we can smell sweet. Joerg Bohlmann is neither a perfumer nor a whale expert. He's a plant biologist at the University of British Columbia in Canada. But his discovery of a new plant gene (基因) might push whales out of the perfume business.

    The gene comes from fir trees, found throughout North America and commonly used as Christmas trees. The trees produce a chemical that can be used in perfume in place of ambergris-but with a catch. "There's a problem that many people wouldn't consider. In the tree, the chemical is mixed with many others. That makes separation a challenge," Bohlmann says. "lt's like trying to isolate sugar from a biscuit. "

     This is where science becomes useful. When Bohlmann learned that fir trees produce the ambergris-like chemical, he decided to use his gene know-how to find the instructions for how to make the ambergris-substitute.

    Bohlmann found that gene and took it out of the tree cells. Then he did something that might sound strange to someone who doesn't work in genetics: Bohlmann put the gene from the tree into yeast (酵母) cells.

    Yeast may sound familiar because it's used to make things like bread, wine and beer. Biologists like to work with yeast because it easily adopts new genes and changes its features and behaviour. When Bohlmann put the fir tree gene into the yeast, the yeast started making the same chemical that had been produced by the tree.

    Perfumers pay big money for ambergris because it is a fixative, which means it holds a smell in place on a person's body.

    "Cheap perfumes smell good in the first hour or so and then everything is gone," explains Bohlmann. "But expensive perfumes are much more stable.  Their smell lasts much longer, for hours or even a day after you apply them. "

    The new chemical, made from the tree genes, can be used as a fixative, too. And using yeast to make it is far cheaper than acquiring ambergris.

    Bohlmann admits he never thought he'd get into the perfume business. But now, he says, producers have been calling to find out how to use his technology in new perfumes.

    It was very late and everyone had left the cafe except an old man who sat in the shadow the leaves of the tree made against the electric light. In the day time the street was dusty, but at night the dew settled the dust and the old man liked to sit late because he was deaf and now at night it was quiet and he felt the difference. The two waiters inside the cafe knew that the old man was a little drunk, and while he was a good client they knew that if he became too drunk he would leave without paying, so they kept watch on him.

     “Last week he tried to commit suicide,” one waiter said. “Why?” “He was in despair.” “What about?” “Nothing.” “How do you know it was nothing?” “He has plenty of money.”

    They sat together at a table that was close against the wall near the door of the cafe and looked at the terrace where the tables were all empty except where the old man sat in the shadow of the leaves of the tree that moved slightly in the wind. A girl and a soldier went by in the street. The street light shone on the brass number on his collar. The girl wore no head covering and hurried beside him.

     “The guard will pick him up,” one waiter said. “What does it matter if he gets what he's after?” “He had better get off the street now. The guard will get him. They went by five minutes ago.”

    The old man sitting in the shadow rapped on his saucer with his glass. The younger waiter went over to him.

     “What do you want?” The old man looked at him. “Another brandy,” he said.

     “You'll be drunk,” the waiter said. The old man looked at him. The waiter went away.

     “He'll stay all night,” he said to his colleague. “I'm sleepy now. I never get into bed before three o'clock. He should have killed himself last week.”

    The waiter took the brandy bottle and another saucer from the counter inside the cafe and marched out to the old man's table. He put down the saucer and poured the glass full of brandy.

     “You should have killed yourself last week,” he said to the deaf man. The old man motioned with his finger. “A little more,” he said. The waiter poured on into the glass so that the brandy slopped over and ran down the stem into the top saucer of the pile. “Thank you,” the old man said. The waiter took the bottle back inside the cafe.He sat down at the table with his colleague again.

     “He's drunk now,” he said. “He's drunk every night.” “What did he want to kill himself for?” “How should I know.” “How did he do it?” “He hung himself with a rope.” “Who cut him down?” “His niece.” “Why did they do it?” “Fear for his soul.” “How much money has he got?” “He's got plenty.” “He must be eighty years old.” “Anyway I should say he was eighty.” “I wish he would go home.I never get to bed before three o'clock. What kind of hour is that to go to bed?” “He stays up because he likes it.” “He's lonely. I'm not lonely. I have a wife waiting in bed for me.” “He had a wife once too.” “A wife would be no good to him now.” “You can't tell. He might be better with a wife.” “His niece looks after him.You said she cut him down.” “I know.” “I wouldn't want to be that old.An old man is a nasty thing.” “Not always.This old man is clean.He drinks without spilling.Even now, drunk.Look at him.” “I don't want to look at him.I wish he would go home.He has no regard for those who must work.”

    The old man looked from his glass across the square, then over at the waiters.

     “Another brandy,” he said, pointing to his glass.The waiter who was in a hurry came over.

     “Finished,” he said, speaking with that omission of syntax stupid people employ when talking to drunken people or foreigners. “No more tonight. Close now.”

     “Another,” said the old man.

     “No. Finished.” The waiter wiped the edge of the table with a towel and shook his head.

    The old man stood up, slowly counted the saucers, took a leather coin purse from his pocket and paid for the drinks, leaving half a peseta tip. The waiter watched him go down the street, a very old man walking unsteadily but with dignity.

     “Why didn't you let him stay and drink?” the unhurried waiter asked. They were putting up the shutters. “It is not half past two.” “I want to go home to bed.” “What is an hour?” “More to me than to him.” “An hour is the same.” “You talk like an old man yourself.He can buy a bottle and drink at home.” “It's not the same.” “No, it is not,” agreed the waiter with a wife. He did not wish to be unjust. He was only in a hurry. “And you? You have no fear of going home before your usual hour?” “Are you trying to insult me?” “No, hombre, only to make a joke.”

     “No,” the waiter who was in a hurry said, rising from pulling down the metal shutters.“I have confidence.I am all confidence.” “You have youth, confidence, and a job,” the older waiter said.“You have everything.” “And what do you lack?” “Everything but work.” “You have everything I have.” “No.I have never had confidence and I am not young.” “Come on. Stop talking nonsense and lock up.” “I am of those who like to stay late at the cafe,” the older waiter said.“With all those who do not want to go to bed.With all those who need a light for the night.” “I want to go home and into bed.” “We are of two different kinds,” the older waiter said.He was now dressed to go home.“It is not only a question of youth and confidence although those things are very beautiful. Each night I am reluctant to close up because there may be someone who needs the cafe.” “Hombre, there are bodegas open all night long.” “You do not understand.This is a clean and pleasant cafe.It is well lighted. The light is very good and also, now, there are shadows of the leaves.”

“Good night,” said the younger waiter.

     “Good night,” the other said. Turning off the electric light he continued the conversation with himself. It was the light of course but it is necessary that the place be clean and pleasant. You do not want music.Certainly you do not want music.Nor can you stand before a bar with dignity although that is all that is provided for these hours. What did he fear? It was not a fear or dread. It was a nothing that he knew too well. It was all a nothing and a man was a nothing too. It was only that and light was all it needed and a certain cleanness and order. Some lived in it and never felt it but he knew it all was nada y pues nada y nada y pues nada.

    He smiled and stood before a bar with a shining steam pressure coffee machine.

     “What's yours?” asked the barman.

     “Nada.” “Otro loco mas,” said the barman and turned away.

     “A little cup,” said the waiter.

    The barman poured it for him.

     “The light is very bright and pleasant but the bar is unpolished,” the waiter said.

    The barman looked at him but did not answer.It was too late at night for conversation.

     “You want another copita?” the barman asked.

     “No, thank you,” said the waiter and went out.He disliked bars and bodegas.A clean, well-lighted cafe was a very different thing.Now, without thinking further, he would go home to his room.He would lie in the bed and finally, with daylight, he would go to sleep.After all, he said to himself, it's probably only insomnia. Many must have it.

    Even by the standards of poor countries, India is alarmingly — and unnecessarily — dirty. It needs to clean up. Most time of year, its capital, Delhi，smells as if something is burning. That is because of many things: the carcinogenic diesel（柴油）that supplies three quarters of the city's motor fuel, the dirty coal that supplies most of its power, the rice stalks that nearby farmers want to clear after the harvest and so on. All these make Delhi's air the most poisonous of any big city.

    This does not just make life unpleasant for a lot of Indians. It kills them. Recent estimates put the annual death toll from breathing PM 2.5 alone at 1.2—2.2 million a year. The lifespan of Delhi residents is shortened by more than ten years, says the University of Chicago-Consumption of dirty water directly causes 200,000 deaths a year, a government think-tank estimates, without measuring its contribution to slower killers such as kidney disease. Some 600 million Indians, nearly half the country, live in areas where clean water is in short supply. As pollutants taint groundwater, and global warming makes the vital monsoon（季风）rains more abnormal, the country is poisoning its own future.

    Indian pollution is a danger to the rest of the world, too. Widespread dumping of antibiotics（抗生素）in rivers has made the country a hotspot for anti-microbial（抗微生物）resistance. Emissions of carbon dioxide, the most common greenhouse gas, grew by 6% a year between 2000 and 2016, compared with 1.3% a year for the world as a whole.

    In the past India has explained its failure to clean up its act by pleading poverty, noting that richer countries were once just as dirty and that its output of waste per person still lags far behind theirs. But India is notably grubby（肮脏的）not just in absolute terms, but also relative to its level of development And it is becoming grubbier.

    It is true that some ways of cutting pollution are expensive. But there are also cheap solutions，such as undoing mistakes that Indian bureaucrats（官僚）have themselves made. By funding rice farmers, for instance, the government has in effect cheered on the overusing of groundwater and the burning of stalks. Rules that encourage the use of coal have not made India more self-reliant, as intended, but instead have led to big imports of foreign coal while blackening India's skies. Much cleaner gas-fired power plants, meanwhile, sit idle.

    Reliant on big business for funding and on the poor for votes, politicians have long ignored middle-class complaints about pollution, failing to give officials the backing to enforce rules. That is a pity, because when India does apply itself to ambitious goals, it often achieves them

    Next year it will send its second rocket to the Moon.

    Narendra Modi, the prime minister, promised with admirable frankness when he took over to rid the country of open defecation（缺陷）. Four and a half years and some $9 billion later, his Clean India campaign claims to have sponsored the building of an astonishing 90 million toilets. This is impressive, but India is still not clean. Its skies, its streets, its rivers and coasts will remain dangerously dirty until they receive similar attention.

    Four teenage girls from Minnesota, US. 120 hours of non-stop togetherness. No cellphones. This is not a reality show, but an adventure journey.

    "It was really perfect," said Julia Ruelle of her recent adventure to the Boundary Waters Canoe Area Wilderness with three of her childhood friends. "By unplugging, we had an amazing time."

    Last year, the 16-year-old took part in an essay contest and carried off a prize. The award was a 5-day canoe and camping adventure with up to three friends. No parents or guides would be there. So Julia invited her friends Anna Wander, Madeline Wilson and Julianna Torelli.

    The four Minnetonka High School juniors arrived in Ely for training the day before they began the journey. They set out the next day at 7 a.m., quickly developing a routine.

    "We were done paddling by noon," Julia said. "We ate lunch at the campsites and then it was time for hammocks (吊床), reading, making friendship bracelets (手镯) and talking."

    The girls had all had experience in the outdoors before.

    Anna had been to the Boundary Waters with her family. "I love how you are separated from everything in your life, especially technology," Anna said. Without her phone, she said, "I'm less worried about things." Madeline, too, had been to the Boundary Waters a few years back. "But this time, I had to paddle right and set up camp," she said. The girls made fire and cooked meal together. No one was ever hungry or homesick, but they were nervous the final night as they waited out a thunderstorm. They left wet sleeping bags in one tent, and squeezed into another for the night. "Every thunderstorm in the Boundary Waters feels huge," Julia said.

    On the car ride home, they were all on their phones catching up with friends. "It was a little at a loss turning my phone on," said Anna. "Mental health can be improved so much in the Boundary Waters. It really helps to get away and reconnect with yourself."

    All of us know that smoking does harm to our health. But do you think everything will be OK as long as you quit smoking?

    Unfortunately, the answer is NO.

    New research has found that even if you give up smoking, the damage it has done to your genes (基因) will stay there for a much longer time. In the research, a team of US scientists studied the blood of 16,000 people. Among them, some were smokers, some used to smoke, and the rest were non-smokers. Scientists compared their genes and found that more than 7, 000 genes of smokers had changed—a number that is one-third of known human genes. According to NBC News, both heart disease and cancer are caused by genetic changes. Some people may have had the changes when they were born, but most people get them in their daily lives while doing things like smoking. When you stop smoking, a lot of these genes will return to normal within five years. This means your body is trying to heal (治愈) itself of the harmful effects of smoking. But the changes in some of the genes stay for longer. They can stay for as long as 30 years, It's almost like leaving a footprint on wet cement (水泥)—it will always be there, even when you've walked away and when the cement becomes dry. Although the study results may make people unhappy, there is a bright side: the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.
