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.

    More than 30,000 people went to the White House on Monday for the 136th Easter Egg Roll (复活节滚彩蛋). President Barack Obama and First Lady Michelle Obama held the event by inviting thousands of kids to color and look for eggs. The theme(主题) of the day was “Hop Into Healthy, Swing Into Shape.” It was part of the First Lady's “Let's Move!” program to reduce obesity rates (肥胖率) among American kids. Mrs. Obama spoke to young reporters about her goal(目标) to get children to eat right and keep moving.

    “We are working to make sure that kids born today grow up healthy, learn how to have balanced meals, and get more physical activity into their lives,” she said.

    Mrs. Obama said she wants children across the nation to understand that "exercise isn't just hard work, it's play. If you're running around with your dog, you're getting exercise. If you walk up the stairs, that's exercise, But if you're sitting in front of the TV or on a computer game, you're not exercising.”

    The First Lady said that for kids who have balanced meals most of the time, having a special snack, like chocolate, will not hurt." And if you are active, you can splurge (挥霍) a little more," she said. Mrs. Obama's favorite "splurge food" is French fries. But she balances her splurging by exercising almost every day. She loves to play tennis and she practices yoga.

    “A lot of kids look up to(敬仰) athletes, and I think it's important for athletes to share their good habits,” Mrs. Obama said. "Kids aren't just going to wake up and be LeBron James. He's practicing and eating right and working out and training. Our athletes can be really good messengers to kids who look up to them--they can say to kids, 'If you really want to be like me, then you really do need to eat your vegetables.'”

    Can exercise during childhood protect you against memory loss many decades later?Exercise early in life seems to have lifelong benefits for the brain,in rats at least.

    "This is an animal study,but it shows that physical activity at a young age is very important一not just for physical development,but for the whole lifelong track of cognitive（认知的）development during ageing,"says Martin Wojtowicz of the University of Toronto,Canada."In humans,it may delay the appearance of Alzheimer's symptoms（阿兹海默氏症）,possibly to the point of preventing them."

    Wojtowicz's team divided 80 young male rats into two equal groups,and placed running wheels in the cages of one group for a period of six weeks.Around four months later—when the rats had reached middle age—the team taught all the rats to connect an electric shock with being in a specific box.When placed in the box,they froze with fear.

    Two weeks later,the team tested the rats in three situations: exactly the same box in the same room,the same box with the room arranged differently,and a completely different box in a different room.

    The rats without access to a running wheel when they were young now froze the same percentage of times in each of these situations,suggesting they couldn't remember which one was dangerous.But those that had been able to run in their youth froze 40 to 50 percent less in both changed box settings.

    “The results suggest the amount of physical activity when we're young,at least for rats,has influence on brain and cognitive health—in the form of better memories—when we're older,"says Arthur Kramer of Northeastern University in Boston,who has found that,in humans,exercise promotes the growth of new brain cells.

    The clearing of my parents' home has made me think about the importance, even centrality of books to the house's life and soul. The house, and our lives in it, would not have been the same without books. The force of the statement comes home to me as I see what happens when shelves are emptied. The rooms suddenly look uncomfortably bare.

    I always rather took it for granted that books furnished a room. The only rooms in our house without books were the dining-room and the bathrooms. Otherwise there were books everywhere: in all the bedrooms, in the drawing-room and in the piano room which became my parents' comfortable winter study.

    I couldn't help feeling that books were rather like people: some more formal and boring, others more entertaining; some simply for show, others with unpromising outsides but rich interiors. They did more, in fact, than furnish a room; they were companions who could offer insights, good advice.

    Now the books are being contributed (not all, to be sure, but very many), and I fear for their future, almost as if they were refugees (难民). “Habent sua fata libelli”, goes as the old Latin saying, originally written by Terentianus; it meant that the fate and future of books were determined by the capability of the reader. But the meaning of the phrase has been misunderstood by time and is now associated with the physical fate of particular books, how they have passed from owner to owner. This is how Walter Benjamin read the saying when he wrote his essay “Unpacking My Library”, which analyses the extraordinarily close relationship between a collector and his or her books.

    When I deal with the books that many are going to charity shops, I hope they will find good homes, I can't help wondering if my generation is the last that will oversee such a process. Books are disappearing, as more and more are bought in electronic form and exist only as bytes of information on e-books or other devices. Does this matter? Could books become more spiritual, as they lose their physicality?

    It is commonly believed that the earliest Chinese paper-cuts appeared during the sixth century. Some scholars believe it was even earlier. Legend has it that during the Western Han Dynasty(206BC-AD24), Emperor Wudi was very sad after one of his favorite concubines, Madame Li, died. A Taoist priest, Li Shaoweng, cut a piece of hemp paper in the shape of Madame Li. When evening fell, the emperor's servants lit candles in his bedroom; the reflection of that paper-cut on the wall made the emperor think about his beloved concubine.

    The Yuxian paper-cut is different from most paper-cuts produced in other regions of China. Paper-cuts from other regions are mostly cut with scissors or knives from single-colored paper, such as red or black paper.

    There are four major procedures to making the Yuxian paper-cut: First, sketch the pattern on the draft paper; second, fasten the draft to the paper to be cut; third, use a knife to carve out the pattern; and fourth, dye (染色) the paper-cut with various colors.

    Precise cutting skills are needed to make a piece of the Yuxian paper-cut, which highlights the craft maker's artistic taste and dyeing skills. That explains the following saying: "The successful making of a Yuxian paper-cut is 30 percent dependent on the maker's cutting skills, and 70 percent on the maker's dyeing skills."

    The traditional Yuxian paper-cut highlights two themes: flowers and characters in Chinese operas. The paper-cut is particularly known for its vivid description of characters in various traditional Chinese operas. In October 2009, the art of Yuxian's paper-cut was added to the list of Intangible Cultural Heritage (非物质文化遗产) established by UNESCO (United Nations Educational, Scientific, and Cultural Organization).
